Meet The Man With Two Functioning Penises
WARNING: There is NSFW material (including pictures) in this post. Please view with discretion. Snakes and lizards have what is called hemipenes, which is essentially a two-headed penis. Two penises on one organism might sound pretty wild, but did you know it can occur on humans as well? About 1 in 5.5 million American men will be affected by a condition known as diphallia, resulting in two penises.Though diphallia is fairly rare on its own, actually finding someone who has the condition is made even more difficult by the fact that it usually accompanies highly deleterious congenital conditions, such as other duplicated organs or spina bifida. When the condition is severe, these defects are insurmountable. The condition isn’t genetic, but could be caused by irregular homeobox gene expression during the 4th week of fetal development. This change in expression is brought upon by mutations in the genes or environmental factors. The degree of the penises’ functionality is entirely dependent on the individual. Some have two penises that are of normal shape, size, and function, while others can have genitalia that is small, malformed, and unable to urinate or ejaculate. One man who has two fully-functional penises goes by DiphallicDude (or DoubleDickDude, which morphed into DDD), as he is committed to keeping his real identity private. He is an American man in his mid-20s, living out on the East Coast. Beyond that, not much is known about who he really is. About a year ago, he did an AMA on Reddit, that turned out to be one of the most popular of all time. He even submitted pictures as proof (obviously NSFW), if you’d like to see what diphallia actually looks like. When he said “Ask Me Anything,” Redditors did not hold back, dying to know what it is like living with that condition. It was revealed that DiphallicDude is bisexual, and has had sex with over 1000 people. While he didn’t go into too explicit of detail about his sexual experiences, he was able to confirm or deny most of the questions he was asked about the mechanics of everything. His book, Double Header: My Life with Two Penises, was released on Christmas Day. It has been holding the title of #1 Bestseller for Kindle in 3 different categories. Upon the book’s release, he has done a series of interviews for radio and web. All of the sexy details left out of the AMA have been described in the book, in addition to all of the other ways diphallia has affected his life. Recently, he gave an interview with BBC Newsbeat, discussing what it was like growing up. His parents cautioned him to keep his condition private and not tell other children. He said that he first thought to keep the secret so he didn’t make other boys feel bad for only having one, and it wasn’t until he was a teenager that he realized that he might have been the one getting ridiculed for being different. When he was in high school, he actually considered having one of the penises removed. He ultimately decided against surgery when he realized that it was something he always had, and it didn’t bother him. NSFW or Humanity in general!! Image: Not Safe for Work

Two black holes to collide!
In a galaxy far, far away, a pair of supermassive black holes appear to be spiraling together toward a cosmic collision of unimaginable scale, astronomers said. The final act of this mating dance, perhaps a mere million years from now, could release as much energy as 100 million of the violent supernova explosions in which stars end their lives, and wreck the galaxy it is in, said S. George Djorgovski of the California Institute of Technology. Most of that energy would go into gravitational waves, the violent ripples of space-time that are predicted but not yet directly detected by Einstein’s theory of general relativity, Djorgovski said. And there could be electromagnetic fireworks as well. According to the theory, he said, the interactions of the black holes would drive nearby stars away, like shingles in a tornado. “However, I think that the nature is never so neat.” Djorgovski is one of the authors of a paper published in the journal Nature. The lead author is Matthew Graham, a computational scientist at Caltech’s Center for Data-Driven Discovery. The merging black holes manifested as a regular flicker in a quasar — a mass of light and energy — in a remote galaxy known as PG 1302-102. The most logical explanation, Graham and his colleagues wrote, is a pair of black holes circling each other less than a light-year apart. If it holds up under scrutiny, the system could be a bonanza for the young field of gravitational wave astronomy. It would also provide a preview of what will happen in our own Milky Way galaxy in a few billion years when it collides with the neighboring Andromeda galaxy. |

Maybe this should have went in the Nope thread. But it's educational kind of...
<div style='text-align:center'><script type='text/javascript' src='http://pshared.5min.com/Scripts/PlayerSeed.js?sid=281&width=480&height=401&playList=518601787'></script><br/></div> DIY Bot Fly Entomologists are not like other people. Lucky enough to score a cool parasitic larva burrowing in your skin after a visit to Central America? The obvious thing to do is to rear your maggot out in your body until it’s an adult fly. For science. In the last week, two entomologists proudly issued bot fly “birth” announcements of their little monsters. For one of them, it was his second try at rearing out the flesh-eating maggots to adults. (His first unsuccessful attempt at bot fly rearing in 2013 did result in a research publication, though, so it wasn’t a wasted effort.) Piotr Nasrecki documented the entire process of his bot fly maggot rearing in a fascinating video. Yes, there is some blood. But you’ll also learn a lot about flies. And entomologists. Below are excerpts from both scientists’ accounts of their maggoty pregnancies; I highly recommend reading both. Both Naskrecki and Wizen have written great explanations of the bot fly life cycle, with beautiful photos. Quote:

I've seen something about that on YouTube once.
Find where the larvae entered the skin, rub some Vaseline around the area then place Saran Wrap over it. The fly apparently gets suffocated in the process and you can pull it out with tweezers as it comes up for air. |

Explanation: Ten Earths could easily fit in the "claw" of this seemingly solar monster. The monster, actually a huge eruptive prominence, is seen moving out from our Sun in this condensed half-hour time-lapse sequence. This large prominence, though, is significant not only for its size, but its shape. The twisted figure eight shape indicates that a complex magnetic field threads through the emerging solar particles. Differential rotation of gas just inside the surface of the Sun might help account for the surface explosion. The five frame sequence was taken in early 2000 by the Sun-orbiting SOHO satellite. Although large prominences and energetic Coronal Mass Ejections (CMEs) are relatively rare, they are again occurring more frequently now that we are near the Solar Maximum, a time of peak sunspot and solar activity in the eleven-year solar cycle. http://apod.nasa.gov/apod/ |

http://s9.postimg.org/qq797xvin/Moon...rint_22480.jpg There's Poop on the Moon It should come as no surprise that the Apollo astronauts left a few things behind after landing on the moon. Since the lunar module could only lift so much weight off the surface, they swapped out unwanted goods and gear for moon rocks. Among those unwanted goods were all kinds of weird things. What kinds of weird things? There were 96 bags of poop, pee, and puke. I know what you're thinking: That makes total sense. That's super gross! But it makes total sense. The Apollo missions brought back a total of 842 pounds of moon rocks, dust, and core samples on six separate missions between 1969 and 1972. That amounts to who knows how many pounds of poop—not to mention the other excrement as well as boring old stuff like tools, golf balls, photographs, cameras, a gold-plated telescope and random symbolic objects. You can get a peek at the manifests that show what the astronauts abandoned in this video: <iframe width="636" height="353" src="//www.youtube.com/embed/QNP8wy3S_kY" frameborder="0" allowfullscreen></iframe> There is, however, scientific value to the things left behind. Astrobiologists, for instance, hope to one day inspect that half-century-old feces to see if the crap has undergone any genetic mutations while in space. Even more mundane gear on the moon's surface offer a unique perspective on how different materials hold up in extreme environments like the moon, where temperatures oscillate between minus 370-degrees to 250-degrees Fahrenheit. What kinds of mundane gear, you wonder? Well, there's actually an entire website devoted to trash on the moon. However, here's a list of the more interesting and unusual items—aside from the 96 bags of poop, pee, and puke:

Biological evidence cannot give specifics about how animals were originally designed. The ultimate authority is the Bible, which was written by men who were inspired of God. What is your biological evidence that tigers and snakes were designed to be plant stalkers? I know all you scriptural arguments, In the bible we read there is a city of Jerico at such a place, we dig, we find it. We read a Hebrew was a big shot in Egypt, we dig, we find it. The bible states credible findable facts. What evidence do you see that supports your idea that animals were intended and designed to be plant only eaters? Put your self in the place of the modern lost bioligist, what would convince him you are not just presenting a doctrine of your own making? (by the way I want you to be correct, I just don't think the scriptures absolutely support you, though they do to a degree) —R.J., U.S. What is your biological evidence that tigers and snakes were designed to be plant stalkers? Biological evidence cannot give specifics about how animals were originally designed. The ultimate authority is the Bible, which was written by men who were inspired of God. The Bible says: Also, to every beast of the earth, to every bird of the air, and to everything that creeps on the earth, in which there is life, I have given every green herb for food; and it was so Genesis 1:30). These biblical statements need to be embraced and not ignored by the biological community. I know all you scriptural arguments, If we refuse to accept the biblical statements, then we give up the foundation of our belief system. The non-Christian doesn’t want us to use the Bible but wants us to reject it and accept his belief system. They accept biological “evidence” as their supreme authority. We need to be discerning and realize when others want us to give up the Bible and instead use biological (or other) “evidence” as the final authority. We need to refuse to do so, and then show the falsity in doing so (Proverbs 26:5) so that the non-Christian will not assume his position is the only correct one. Why would we want to give up our starting point and accept theirs? It should be the other way around—they need to give up their reliance on man-made ideas about the past and instead use the Bible! In the bible we read there is a city of Jerico at such a place, we dig, we find it. We read a Hebrew was a big shot in Egypt, we dig, we find it. The bible states credible findable facts. Archaeological findings do not provide an absolute authority. As confirmation of the Word of God, they are important, but they are secondary to God and His Word. On the other hand, lack of archaeological evidence (for example, not finding the cursed fig tree Mark 11:13-21) will not invalidate the scriptures. The Scriptures are the Word of God, which is truth and will therefore have evidence of its veracity. What evidence do you see that supports your idea that animals were intended and designed to be plant only eaters? Again, we accept that all animals were originally designed to eat green plants because this is what the Bible teaches in Genesis 1:30. We don’t look to the “evidence” to see if animals were originally vegetarian, and then confirm this with the Bible. That said, there have been examples of meat-eating animals that have survived on non-meat diets (e.g. the lion that refused to eat meat, the vulture that refused to eat meat, and so on). Just because an animal has a carnivorous diet today, doesn’t mean its ancestors only ate meat, or that it can’t survive on a vegetarian diet today. The un-petition I am so glad that AiG is standing strong and growing fast. What I read from Ken's blog about the petitions is actually encouraging. You would not be receiving so much opposition if you did not have any potential...and this also shows just how “dangerous” evangelism is to lost souls—they might be saved!!! Thank you! Thank you! Thank you! —B.C., U.S. Put your self in the place of the modern lost bioligist, All of us were “lost,” before God graciously saved us, so we can sympathize with the biologist (as a matter of fact, some of us are biologists!). However, as Christians, we now have a different foundation (the Bible) from the non-Christian, even though we both study the same “evidence.” When Jesus came in human form to teach mankind, did He give up the Word of God as the authority? By no means! He used it. So, we must not ignore God’s Word, and rely only on the “evidence.” Instead, we should ask the lost biologist to put the Bible in the position it deserves—the supreme authority in all matters on which it touches, including biology. We can also challenge his position, if it is unbiblical, so that he realizes biology makes little sense without the Bible. For example: Why do we observe animals varying within their respective kinds and not changing into other kinds? Why do we observe life giving rise to life (Law of Biogenesis), not abiogenesis, which molecules-to-man evolution requires? Why are laws of nature uniform in the first place? What would convince him you are not just presenting a doctrine of your own making? The doctrine of animals originally being vegetarian is obviously not a doctrine of our own making, as it was given thousands of years ago by the Creator to His creation (Genesis 1:30). We can present what the Bible says to the non-Christian, but it is not up to us to convince him to change his mind. Conviction comes from the Holy Spirit (2 Thessalonians 2:13), who opens hearts. When we witness to others, we can: Pray that God would open that person’s heart. Question the false foundation that the person accepts and show that it is faulty (such questions above help). This will take time. Provide the correct biblical foundation as taught in Genesis and the rest of the Bible. Share the gospel and show how it relates. The point isn’t to just convince someone that creation is true but to present them with the good news of salvation in Christ.

Many of the Bible’s statements about astronomy went against the generally accepted teachings of the past. Modern science, however, has confirmed what the Bible has taught. Taking Back Astronomy Editor’s note: this article is adapted from a chapter of Dr. Lisle’s new book, Taking Back Astronomy. While some people consider astronomy to be a weak area of creation-origins study, this fascinating just-released book contains enough intriguing content to cause even the most hard-hearted of our day to stop and consider the book’s eye-opening findings. It is not commonly known that many of the Bible’s statements about astronomy went against the generally accepted teachings of the time. Undoubtedly, many of these verses would have seemed counterintuitive, and may have been difficult to believe when they were first written. Modern science, however, has confirmed what the Bible has taught. As in all things, the Bible is absolutely correct when it teaches about the universe. The earth is round Consider Isaiah 40:22 which mentions the “circle of the earth.” This description is certainly fitting—particularly when the earth is viewed from space; the earth always appears as a circle, since it is round. Curiously, many astronomy textbooks credit Pythagoras (c. 570–500 B.C.) with being the first person to assert that the earth is round. However, Isaiah is generally acknowledged to have been written in the 700s B.C. The secular astronomers before the time of Pythagoras must have thought the Bible was wrong about its teaching of a round earth, yet the Bible was exactly right. The earth floats in space A very interesting verse to consider is Job 26:7 which states that God “hangs the earth on nothing.” This verse expresses (in a poetic way) the fact that the earth is unsupported by any other object—something quite unnatural for ancient writers to imagine. Indeed, the earth does float in space. We now have pictures of the earth taken from space that show it floating in the cosmic void. Universe expansion The Bible indicates in several places that the universe has been “stretched out” or expanded. For example, Isaiah 40:22 teaches that God “stretches out the heavens like a curtain, and spreads them out like a tent to dwell in.” This would suggest that the universe has actually increased in size since its creation. God has stretched it out. He has expanded it (and is perhaps still expanding it). This verse, too, must have seemed very strange when it was first written. In fact, secular scientists once believed that the universe was eternal and unchanging. The idea of an expanding universe would have been considered nonsense to most scientists of the past. It must have been tempting for Christians to reject what the Bible teaches about the expansion of the universe. Perhaps some Christians tried to “reinterpret” Isaiah 40:22, and read it in an unnatural way so that they wouldn’t have to believe in an expanding universe. When the world believes one thing, and the Bible teaches another, it is always tempting to think that God got the details wrong, but God is never wrong. Today, most astronomers acknowledge that the universe is indeed expanding. The number of stars A stellar guy! You wouldn’t think that an astrophysicist (that’s an astronomer who’s taken a lot more math!) would be able to communicate at a level that even a young person would understand. But with Dr. Jason Lisle (the author of this article), that’s just not the case. Dr. Lisle has been flying all over America, giving superb, well-illustrated talks on astronomy, dinosaurs and biblical authority to groups young and old. When he’s in the office, Dr. Lisle has been putting the finishing touches on the first presentation for the new planetarium inside the Creation Museum, and writing for our new magazine. Although Dr. Lisle will be busier here in the office, he will still be available to speak on a limited basis. To inquire, go to our Request an event page. Genesis 22:17 teaches that God would multiply Abraham’s descendants “as the stars of the heaven, and as the sand which is on the sea shore.” Genesis 32:12 makes it clear that this represents a number which is uncountable by humans: “the sand of the sea, which cannot be numbered for multitude.” These are excellent analogies. Clearly the sand of the sea and the stars in the universe cannot be counted exactly by humans, though of course, they can be roughly estimated. It was not always believed that the stars were so numerous. The astronomer Claudius Ptolemy (A.D. 150) cataloged 1,022 stars in his work The Almagest. The total number of stars that can be distinctly seen (from both hemispheres under ideal, dark sky conditions) with the unaided eye is around 10,000. Powerful telescopes today allow us to estimate that our single galaxy alone contains over 100 billion stars. And astronomers believe that there are more galaxies in the visible universe than there are stars in our own galaxy. Modern science certainly confirms Genesis 22:17. Confirming the Bible Today, the reliability of the Bible is increasingly attacked. Can we really trust it in our modern age of technology and science? As we have seen, science is not an enemy of the Bible. On the contrary, modern science has already confirmed much of what the Bible teaches about astronomy. Many of the biblical teachings are now accepted in science textbooks. As AiG President Ken Ham has written so often (and which is the theme of the year for AiG in 2006), Christians need to take back those fields of science, like astronomy, which have been hijacked by evolutionists in order to promote their secular worldview. |

Where’s the best evidence for the Creator? You don’t have to look far! In this new 16-part video series, Dr. David Menton, former anatomy teacher and professor of the year, gives you an insider’s look at the wonders of the human body. You don’t have to look far to find the best evidence for the Creator. In fact, your eyes are a good starting point. Or go a little deeper and check out your heart, lungs, digestive system, bones, blood, and more. With a microscope, you’ll find a billion more powerful evidences that patrol your blood every day—your feisty white blood cells, which could only be the handiwork of a Master Designer. Body of Evidence, a new 16-episode, 8-DVD series on anatomy and physiology, explores the wonders of the human body. Your expert guide is Dr. David Menton, loved worldwide for his humorous and insightful talks that leave audiences in hushed awe at the Creator’s wisdom. An award-winning retired Professor Emeritus who served 34 years at the Washington University School of Medicine, Dr. Menton is joined by two high schoolers and employs an amazing collection of anatomical props, models, and microscopic images to teach them (and us) about God’s amazing designs for life. Geared for teens and adults, Body of Evidence is an excellent resource for homeschool families, Christian school anatomy supplementation, or anyone who wants to show his skeptical friends some of the most amazing designs that point unmistakably to our Creator. You’ll be astounded as you move from organs that you thought were familiar—like the kidney—to electron-microscope views of various complex structures, such as the glomerulus. These bizarre-looking cell structures filter your blood and remove salts, metabolic by-products, and other substances far more efficiently than any filter made by human engineers. Discover how they accomplish this vital mission in concert with an array of blood vessels, hormones, “salt sinks,” and other ingeniously designed cells and processes. As Dr. Menton often says, “The Lord thinks of everything.” Learn how God designed your respiratory system so that air could be heated and filtered before entering your lungs. Somehow unwanted air particles must be trapped and removed. So God designed goblet cells in the upper respiratory tract to produce mucus, which traps particles. God also designed millions of hair-like structures, called cilia, that line the tract and push the mucus up and out. But if the sticky mucus came into direct contact with the cilia, it would gunk up the cilia. So the wise Creator added a water-like substance to protect the cilia, maintaining just the right fluid level so that the mucus can float on top of the liquid. Over 6.9 billion “bodies of evidence” are walking the earth right now, but many of them shut their eyes to any evidence for the Creator. Dr. Menton answers their frequent demand, “What’s the best evidence for the Creator?” with, “Whatever I’m currently looking at.” The helpful images and engaging teaching in this unique new DVD series are sure to inspire awe, leaving no doubt about the origin of these wonders. |
Scientists are 3d printing liver cells....
http://s13.postimg.org/itwfyfa07/109...968203_n_j.jpg Liver-like cells made with 3D printer The exploding technology trend of 3D printing, which has already been used to manufacture everything from food to jewelry, has made its way into the realm of biomedical research, with one California company recently announcing that it had "bioprinted" 3D liver cells. The San Diego-based company Organovo says it has used the technology behind 3D printing to create samples of liver cells that function as they would in a human. The firm presented its findings at the Experimental Biology conference in Boston in April. "We have demonstrated the power of bioprinting to create functional human tissue that replicates human biology better than what has come before," Organovo said in a news release. The company's researchers used a gel to build three types of liver cells and arranged them into the same kind of three-dimensional cell architecture found in a human liver. Although not fully functional, the 3D cells were able to produce some of the same proteins as an actual liver does and interacted with each other and with compounds introduced into the tissue as they would in the body. That means biomedical researchers could potentially use the tissue to test drugs or investigate the effect of certain diseases. Organovo's researchers are not the first to apply 3D printing to biomedicine. Doctors at the University of Michigan last year used a 3D printer to build a synthetic trachea for a child with a birth defect that had collapsed her airway, and as scientists and engineers get more familiar with the technology its uses will no doubt grow. To hear more about how Organovo made its 3D liver, watch the interview above with the company's CEO, Keith Murphy, on CBC's Lang & O'Leary Exchange. |

ESA/Rosetta/NAVCAM </figcaption> </figure> The Rosetta spacecraft has been orbiting the comet 67P/Churyumov-Gerasimenko for the past few months, and in addition to taking stunning photographs and making a historic landing, it's been analyzing the comet with its onboard devices, including COSIMA (COmetary Secondary Ion Mass Analyser). The spacecraft was able to capture grains from the comet’s coma in an aerogel plate. Nonetheless, most of the grains captured this way disintegrated anyway. Although that destroyed the grains, it told us something about the comet's recent history in the process. Aerogel, nicknamed ‘frozen smoke’, is a very soft gel which replaces the liquid in a traditional gel with gas. Because of its softness, aerogel makes a good medium for capturing fast-moving dust, as it has less chance of destroying the grain than with a hard impact. Although the grains that were captured at relatively low speeds—about 1-10 meters per second—this implied that the grains were structurally weak to not be able to survive the soft impact with the gel. <figure class="image center large full-width" style="width:640px">http://cdn.arstechnica.net/wp-conten...ns-640x321.jpg<figcaption class="caption">Enlarge / The grains, collected by COSIMA. Image A) shows the dust particle named 'Eloi' by the researchers, like the post-human creatures in H.G. Wells' novel. Eloi crumbled upon capture. B) shows another particle, named Arvid, which shattered. ESA/Rosetta/MPS for COSIMA Team MPS/CSNSM/UNIBW/TUORLA/IWF/IAS/ESA/BUW/MPE/LPC2E/LCM/FMI/UTU/LISA/UOFC/vH&S </figcaption></figure> It also implies that the grains didn’t have a water-ice component. If they did, they wouldn’t shatter in the gel—rather, the watery component would evaporate, leaving only the rocky component to be studied. And if the grain was entirely ice, the whole thing would have evaporated, leaving nothing behind. The comet therefore has an outer layer of pure dust with no water-ice. The dust is high in sodium and fluffy. (Yes, 'fluffy’ is a scientific term, meaning porous like a sponge). The researchers concluded that the dust originated in a layer of the comet that was built up over the past four years. The comet takes six and a half years to orbit the Sun, and so for the past four years, the comet’s been in the more distant part of its orbit—greater than four astronomical units away from the Sun. When it gets closer to the Sun, 67P/Churyumov-Gerasimenko heats up and begins to outgas, producing the comet’s coma (the atmosphere around the body itself) and its tail. This process ejects the outer dusty layer and in the process pushing the lower material, which contains an ice-dust mixture, closer to the surface. It has been previously suggested that comets might develop such a dusty layer as they spend time far from the Sun before releasing it in the closer part of their orbit. And, on its previous close pass in 2008, this same comet was observed by telescope, shedding the dust layer it had built up. Back then, its dust was entirely lost when the comet was relatively close to the Sun at a little over two and a half astronomical units away. It reached a similar distance earlier this month, and presumably finished losing its outer dusty layer yet again. It will begin building it up again as its orbit shifts and it begins edging further into the Solar System. The study confirms that the comet’s dust originates from the Solar System’s interplanetary dust. And since the dust is high in sodium, it explains why some comets have been observed to be high in sodium. Nature, 2015. DOI: 10.1038/nature14159 (About DOIs) </section> |

Approximately 3.3 million years ago someone began chipping away at a rock by the side of a river. Eventually, this chipping formed the rock into a tool used, perhaps, to prepare meat or crack nuts. And this technological feat occurred before humans even showed up on the evolutionary scene. That's the conclusion of an analysis published today in Nature of the oldest stone tools yet discovered. Unearthed in a dried-up riverbed in Kenya, the shards of scarred rock, including what appear to be early hammers and cutting instruments, predate the previous record holder by around 700,000 years. Though it’s unclear who made the tools, the find is the latest and most convincing in a string of evidence that toolmaking began before any members of the Homo genus walked the Earth.

A few years old but I hadn't seen it:
Archaeology has long associated advanced blade production with the Upper Palaeolithic period, about 30,000-40,000 years ago, linked with the emergence of Homo Sapiens and cultural features such as cave art. Now researchers at Tel Aviv University have uncovered evidence which shows that "modern" blade production was also an element of Amudian industry during the late Lower Paleolithic period, 200,000-400,000 years ago as part of the Acheulo-Yabrudian cultural complex, a geographically limited group of hominins who lived in modern-day Israel, Lebanon, Syria and Jordan. http://www.sciencedaily.com/releases...1017111610.htm |
An interesting article overall, but the first part is the most interesting. It appears that we can fly by Pluto, but it would be extremely difficult to actually land on it or go into orbit around it. You have to go really fast to get there in under a decade, and Pluto's gravity is so low that you can't use it to capture the spacecraft or even slow it down much. You'd have to take an enormous amount of fuel to slow down, which isn't currently feasible.

it could've siphoned some gas from uranus
Hey, I'm not too old for 4th grade humor. Well, if the schedule's right, New Horizons just did that Pluto drive-by. We won't see pics until tomorrow, I guess. I'm thinking, though: What if I were out there in my spacesuit just hanging around with Pluto and Charon, minding my own business, and this half ton thing blows past me at 30,000 mph? There's no shock wave or wake, I would imagine. But would I feel anything? Could I even see it? |

Wow, Musk has made a lot of progress on his idea of a hyperloop.
http://www.iflscience.com/elon-musks...sort-happening The Hyperloop is a concept for a transportation system whereby a capsule inside a near-vacuum tube can accelerate up to around 1,220 kilometers (760 miles) per hour, providing a rapid transport system for passengers. It’s estimated that a trip from Washington D.C. to New York City would take just 30 minutes. It sounds like the stuff of science fiction – and at the moment, it is. But the company that is aiming to develop this technology has announced they are making significant progress, and will start building a test track next year in Quay Valley, California. SpaceX and Tesla CEO Elon Musk first proposed the idea of the Hyperloop in 2013. At the time, he said he wasn’t looking to develop the idea himself, but was instead releasing the idea for others to develop. Thus sprung up Hyperloop Transportation Technologies (HTT), founded by JumpStartFund, who decided to push ahead with Hyperloop’s development. The company has been looking for volunteers across a range of disciplines – from engineers to technicians – to help make the dream a reality. The company has now revealed they have more than 400 professionals on board, while companies including Oerlikon, Aecom and Hodgetts & Fung were involved to provide support. And they also confirmed 2016 as the year they would start building the first test track. |

Quantum Mechanics Just Got "Spookier" An international collaboration and a newly published paper may have just settled a century old physics debate. Quantum mechanics is spooky. Entanglement – a component of quantum mechanics – tells us that two particles can be directly connected even across vast distances. If you measure the spin of one particle, you immediately know the spin of its counterpart. Physicists have labeled this behavior as “spooky” as it doesn’t follow everyday logic. Common sense tells us that objects across the universe cannot possibly be connected, yet in the quantum realm, they are. Quantum mechanics also says that properties of particles are only fixed when the particle is observed. Some physicists, including Albert Einstein, opposed this notion as it went against the very nature of the real world. In the 1930s when quantum mechanics was an emerging field, Einstein was a proponent of “local realism,” arguing that only close objects could affect each other. Einstein and other physicists developed the ‘hidden variables theory’ to explain the spooky behavior. They argued that our knowledge of quantum mechanics was incomplete and there could be hidden variables that we didn’t yet understand. In the 1960s a physicist named John Bell devised a mathematical expression – called an inequality – to test for these so-called hidden variables. He realized that if these hidden variables did indeed exist, there would be a limit to how connected the particles were. If they exceeded the set limit then the hidden variables did not exist. However, the experiment – known as Bell’s Inequality – did not definitively close the door on local realism. The tests involved entangled photons, which can get lost along the way, and experimenters might not detect all photons produced. In the new experiment, led by Bas Hansen of Delft University of Technology in the Netherlands, we have two researchers – we will call them Alice and Bob – in two laboratories 1.3 kilometers apart. Each laboratory is set up with a diamond chip containing an electron whose spin was entangled with a photon. The photons were then sent to a third lab in between Alice and Bob, where a detector records the arrival time. If two photons arrived at the same time they would be entangled, resulting in the electrons being entangled as well. The experiment took place over a span of nine days. In that time, researchers recorded 245 successful entanglements. While other tests over the last few decades have also supported Bell’s limit, this new experiment learns from their shortcomings to overcome experimental pitfalls. Previous test used inefficient detectors, only measuring a small number of the particles passing through them. Recent experiments used near-perfect detectors, but the entangled particles were close enough to potentially communicate. In the new experiment, the team used high-quality detectors and measurements collected before the electrons could possibly exchange signals with each other, making it the first to close both loopholes. The results of this experiment have big implications for the world of quantum cryptography – meaning entangled photons could potentially create secure encryption keys. Closing the loopholes would ensure that computer systems could detect if anyone tried to intercept the keys, as it would break the entanglement and trigger an alarm. |
Scientists confirm that the Paleo diet is nonsense
http://i.kinja-img.com/gawker-media/...rcnmvn8wdw.jpg The theory behind the very trendy high-protein/low-carb Paleo diet is that we should mimic the diets of our Paleolithic ancestors, eating mainly meat, fish, and a restricted list of pre-agricultural vegetables and fruit. (There is some debate within the Paleo community about which starchy vegetables and how much of them are Paleo-approved, but most recommend limiting them if not barring them entirely.) But according to a new study in The Quarterly Review of Biology, the low-carb interpretation of the paleolithic menu is probably all wrong. The researchers posit that our cavemen and cavewoman ancestors loved—and needed—carbs as much as we do, even if they gathered them instead of cultivated them. Based on a review of archaeological, genetic and physiological evidence, the researchers found that “plant carbohydrates and meat were both necessary and complementary dietary components” in the evolution of humans. Examination of 3-million-year-old teeth and the plant-life in the regions where our ancestors lived also signal that they were eating tubers and other starchy vegetables. The root vegetables many modern Paleo dieters avoid likely played a key role in the original Paleo diet for a number of reasons. Because these plants grow underground, they were likely a key source of nutrition for our gathering forebears, who could dig them up as needed, the researchers say, and probably hunted much less than once thought. “Although meat may have been a preferred food, the energy expenditure required to obtain it may have been far greater than that used for collecting tubers from a reliable source,” the researchers write. (Worth noting: The researchers believe the tubers were collected by postmenopausal women, who shared them with the younger female relatives, which in turn, allowed them to have more babies. Men are not mentioned.) Nutritional requirements and evolutionary evidence also support the idea that cavemen did not live on meat alone. As the brain grew during this period, more energy was needed, and it likely came from carbohydrates, not protein, too much of which can be toxic to the human body and even cause death. This is further supported by evidence of two other major developments at the time: Saliva was evolving to better break down starch-rich plants, and our forebears were learning to cook. Both of these factors converged to make the vegetables tastier and easier to digest, providing the necessary energy for brain growth. These starchy plants also likely supported “improved reproductive functions,” including fetal growth and extra calories for lactating mothers. The upshot? Paleo dieters, go eat some potatoes. |
Detoxes: an undefined scam
Why you feel good during a detox Any diet promising a quick fix is always too good to be true. Good health takes time and dedication. Still, that doesn’t stop fad diets and their marketers from gumming up the airways with advertisements. One kind of fad diet always makes the rounds this time of year: the cleanse, or “detox” diet. What exactly is a cleanse? You’ll be hard-pressed to find a specific definition for either of these interchangeable terms. Presumably, the goal of a cleanse is to eliminate harmful substances from the body by “flushing” them out through a combination of caloric restriction and a liquid-only diet. Many cleanses are supposedly aimed at specific body parts, whether it’s a liver cleanse, a colon cleanse, or the almighty Master Cleanse. Cleanses and detox diets often involve strict food limitations, usually allowing only fruit and vegetable juice, or other drinks. The master cleanse, for example, prescribes a daily six to twelve glasses of lemonade containing maple syrup and cayenne pepper. Supposedly, this concoction will remove toxins from the body, and according to its creator, support the “elimination of every kind of disease.” While minor differences might differentiate one fad cleanse or detox diet from another, no specific one is worth dissecting in detail, since a new one will be around the corner, claiming to be more effective than the others. In simple terms, detox and cleanses hinge on the premise that the human body accumulates “toxins” as a result of exposure to pesticides, pollutants, food additives, or simply from inadequate flushing of metabolic waste. Does the body need cleansing? It is important to understand, however, that the human body is remarkably resilient. The liver, kidneys, lungs, and several other organs work around the clock to remove harmful substances and excrete waste products of metabolism. They don’t need any help from pepper-infused lemonade. Moreover, there is evidence that commercial detox supplements are not based on facts. A 2009 investigation found that not a single company behind 15 commercial cleanses could name the toxins targeted by their treatment, agree on the definition of the word ‘detox’, or even supply evidence that their products work. The fact that no company can name the toxin their product targets reveals just how little of an effect cleanses have. To scientifically determine the effectiveness of a treatment, the toxin being investigated first needs to be identified in order to accurately measure its accumulation in the body. Then, researchers would investigate the effects of pharmaceuticals or supplements on the toxin. Finally, scientists would begin to explore a hypothesis for why the toxin is affected by a particular drug or supplement. For example, scientists researching the effects of organochlorine pesticides, which are known to accumulate in mammals, not only know the name of the toxin they are researching, but they have also determined that accumulation can be limited by the pharmaceutical Orlistat. In fact, the mechanism behind Orlistat’s effect on organochlorine is largely understood: normally, organochlorine pesticides can move between the liver and intestines. Orlistat confines the toxins to the intestines, where they are removed as waste. This is not to say that the human body does not accumulate low levels of toxicants, such as heavy metals or certain fat soluble substances. Rather, the takeaway is that detox diets or cleanses have no demonstrable effect on the removal or excretion of these toxicants. How can you explain apparent cleanse benefits? Fad cleanses often spread through word-of-mouth despite their apparent lack of beneficial health effects. Since a cleanse involves caloric restriction, temporary weight loss often results. This is a result of glycogen loss from the liver and muscles, not fat loss. Under caloric restriction, the body’s glycogen stores can easily be depleted in 24-48 hours, resulting in a weight loss of several pounds (both from the glycogen burnt, and the water weight associated with glycogen storage). Once a regular eating schedule is resumed, however, the glycogen and water come rushing back. Nevertheless, this temporary weight loss leads a lot of people to believe the cleanse they just completed had some beneficial health effects. Not to mention - most people eat poorly. A cleanse usually brings with it vegetable and fruit consumption, which brings a host of nutrients their regular diet is likely severely lacking in. Instead of doing a cleanse for a New Year’s resolution, focus on long-term sustainable health habits, like eating nutritious food on a daily basis. Leafy greens, ample protein, and food chock-full of vitamins is not just tastier than a cleanse, but will actually benefit your body too. |

Mars has flowing water....
NASA Confirms Evidence That Liquid Water Flows on Today’s Mars New findings from NASA's Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times. “Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water -- albeit briny -- is flowing today on the surface of Mars.” These downhill flows, known as recurring slope lineae (RSL), often have been described as possibly related to liquid water. The new findings of hydrated salts on the slopes point to what that relationship may be to these dark features. The hydrated salts would lower the freezing point of a liquid brine, just as salt on roads here on Earth causes ice and snow to melt more rapidly. Scientists say it’s likely a shallow subsurface flow, with enough water wicking to the surface to explain the darkening. "We found the hydrated salts only when the seasonal features were widest, which suggests that either the dark streaks themselves or a process that forms them is the source of the hydration. In either case, the detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks," said Lujendra Ojha of the Georgia Institute of Technology (Georgia Tech) in Atlanta, lead author of a report on these findings published Sept. 28 by Nature Geoscience. Ojha first noticed these puzzling features as a University of Arizona undergraduate student in 2010, using images from the MRO's High Resolution Imaging Science Experiment (HiRISE). HiRISE observations now have documented RSL at dozens of sites on Mars. The new study pairs HiRISE observations with mineral mapping by MRO’s Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). The spectrometer observations show signatures of hydrated salts at multiple RSL locations, but only when the dark features were relatively wide. When the researchers looked at the same locations and RSL weren't as extensive, they detected no hydrated salt. Ojha and his co-authors interpret the spectral signatures as caused by hydrated minerals called perchlorates. The hydrated salts most consistent with the chemical signatures are likely a mixture of magnesium perchlorate, magnesium chlorate and sodium perchlorate. Some perchlorates have been shown to keep liquids from freezing even when conditions are as cold as minus 94 degrees Fahrenheit (minus 70 Celsius). On Earth, naturally produced perchlorates are concentrated in deserts, and some types of perchlorates can be used as rocket propellant. Perchlorates have previously been seen on Mars. NASA's Phoenix lander and Curiosity rover both found them in the planet's soil, and some scientists believe that the Viking missions in the 1970s measured signatures of these salts. However, this study of RSL detected perchlorates, now in hydrated form, in different areas than those explored by the landers. This also is the first time perchlorates have been identified from orbit. MRO has been examining Mars since 2006 with its six science instruments. "The ability of MRO to observe for multiple Mars years with a payload able to see the fine detail of these features has enabled findings such as these: first identifying the puzzling seasonal streaks and now making a big step towards explaining what they are," said Rich Zurek, MRO project scientist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. For Ojha, the new findings are more proof that the mysterious lines he first saw darkening Martian slopes five years ago are, indeed, present-day water. "When most people talk about water on Mars, they're usually talking about ancient water or frozen water," he said. "Now we know there’s more to the story. This is the first spectral detection that unambiguously supports our liquid water-formation hypotheses for RSL." The discovery is the latest of many breakthroughs by NASA’s Mars missions. “It took multiple spacecraft over several years to solve this mystery, and now we know there is liquid water on the surface of this cold, desert planet,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program at the agency’s headquarters in Washington. “It seems that the more we study Mars, the more we learn how life could be supported and where there are resources to support life in the future.” |
We already know there is ice on the poles. Seems easier to melt ice than desalination of water on a planetary scale.

Congress Just Gave NASA A Massive Budget For Next Year Good news, everyone. NASA’s latest budget has just been put forward by Congress – and they have allocated the agency $750 million more than they requested. This means the agency’s full budget for 2016 is $19.3 billion, which incredibly – in an age of cutting costs – is almost $1.3 billion more than last year. The budget increases funding to several key programs at NASA, including its Commercial Crew program, its Space Launch System (SLS) rocket, and the Orion spacecraft. "We are going back into space with Americans on American rockets, and we are going to Mars," Senator Bill Nelson said yesterday. Perhaps most interestingly, $175 million of the budget has been set aside for the Europa Multi-Flyby Mission, a spacecraft that will be sent to Europa in the early 2020s, and the budget dictates that NASA must include a lander for the surface of this icy moon of Jupiter. "This mission shall include an orbiter with a lander that will include competitively selected instruments and that funds shall be used to finalize the mission design concept," it reads, reported Ars Technica. A lander has been touted for the upcoming Europa mission before, but NASA has not been keen to firmly commit to anything yet, as there are many unknowns about undertaking such a landing. It remains to be seen how they'll go forward with this request. Nonetheless, the large amount of funding essentially allows NASA to meet most of the other goals it has set itself. Crucially, they were given the $1.243 billion of funding for the Commercial Crew program that they have been pushing so hard for. Administrator Charlie Bolden recently told IFLScience that he counted this – getting SpaceX and Boeing’s manned spacecraft up and running – as one of the key goals of his time in office. <sup></sup> Elsewhere, planetary science has received a boost in the form of $1.631 billion – $270 million above what the President requested. According to The Planetary Society, this "allows both the MER Opportunity rover and the Lunar Reconnaissance Orbiter to continue science operations." The upcoming Mars 2020 rover, meanwhile, gets a $22 million boost. The huge SLS, which Congress seems very keen to overfund, has been given $2 billion, $640 million above the $1.36 billion requested by the President. The SLS, if you aren’t aware, will eventually be used to take humans to Mars with the Orion spacecraft, which has been given an increase to $1.91 billion. Of the areas to miss out on their requested levels of funding, one is the Earth Science Division, which received $1.921 billion – less than the President’s request but $149 million more than last year. Another is the Space Technology Mission Directorate (STMD), which gets $686 million – $39 million less than requested, but $90 million more than last year. The budget still needs to pass a vote in Congress this week, which seems likely at the moment, although a controversial surveillance bill was snuck in along with it. If it gets by this test, the White House will almost certainly sign it into law. Onto Europa, then. |

Excellent way to spend money. Hopefully NASA can reignite the dreams of our kids for space.
|
I honestly feel that the vast majority of that money should be used to develop "warp drives", space time bending, worm hole generation, or what ever the hell the most promising theory is for solving the distance vs speed hurdle.
It will eventually be done, and all these rockets that have been sent on the furthermost missions will have been a complete waste because we will be able to get to the destination and back before the original mission even makes it there. I believe we will shrink space within 25 years. |
