Marijuana May Stop the Spread of HIV Researchers may just give you a reason to light up soon. BY DIANE ANDERSON-MINSHALL People with HIV (and other conditions) have used prescription marijuana to treat the side effects of medication, but a new study published in the journal AIDS Research and Human Retroviruses, recently showed that daily doses of may even help combat the disease. According to Leaf Science, the study by Louisiana State University researchers showed that THC (a main component of marijuana) given to monkeys over a 17-month period decreased damage to immune tissue of the gut — an important site of HIV infection — by acting at the gene level. “It adds to the picture and it builds a little bit more information around the potential mechanisms that might be playing a role in the modulation of the infection,” said the lead author of the study, Dr. Patricia Molina. Leaf Science reports that while HIV normally spreads by infecting and ultimately killing immune cells, researchers "observed higher levels of healthy immune cells in animals that received THC – something they noticed in a previous study as well." In 2011, Molina and her team discovered that HIV-positive monkeys monkeys treated with THC had lower levels of viral infection, higher numbers of immune cells, better survival rates, and less weight loss. The results of the study, which was funded by the National Institutes of Health and the National Institute on Drug Abuse, were unexpected. “When we started the study, we thought it was going to increase viral load, we thought it was going to decrease lymphocyte counts much more dramatically, and we did not see that," she told Leaf. "If anything, it looks like there might be some beneficial immunomodulation, particularly at the early stages of infection.” The next stop, she says, will be to try to understand why marijuana might help stop the spread of HIV so that treatments can be developed that are more specific to how THC works. |

The magazine unveiled the photos online and announced them via Twitter @SI_Swimsuit. "One small step for swimsuit, one giant leap for mankind," someone adapting astronaut Neil Armstrong's famous words as he stepped on the surface of the moon for the first time, said at the end of the Sports Illustrated video. ZERO-G passengers experience weightlessness as pilots flying the company's modified Boeing 727 fly in parabolic arcs while thousands of feet above Earth's surface. As the plane tilts its nose and flies on the downslope of the parabola, passengers experience about 30 seconds of weightlessness at a time. For Upton's shoot, the company flew a series of 13 weightless parabolas and four parabolas imitating lunar gravity, according to ZERO-G. Upton floated through the plane in gold and white two-pieces and a gold lamé zip-up one piece. She also posed in droplets of weightless water while floating upside down in the plane for the magazine's 50th swimsuit issue. The weightless shoot was four years in the making, according to a passengerheard speaking in the Sports Illustrated video.

A lung you say? YES! Let me dial it in the computer here.. one moment... TA-DAAH! A replacement lung!
Human lung made in lab for first time (CNN) -- For the first time, scientists have created human lungs in a lab -- an exciting step forward in regenerative medicine, but an advance that likely won't help patients for many years. "It's so darn cool," said Joan Nichols, a researcher at the University of Texas Medical Branch. "It's been science fiction and we're moving into science fact." If the lungs work -- and that's a big if -- they could help the more than 1,600 people awaiting a lung transplant. Lungs are one of many body parts being manufactured in the lab -- some parts, such as tracheas and livers, are even further along. "Whole-organ engineering is going to work as a solution to the organ donor shortage," said Dr. Stephen Badylak, deputy director of the McGowan Institute for Regenerative Medicine at the University of Pittsburgh. The researchers in Galveston, Texas, started with lungs from two children who'd died from trauma, most likely a car accident, Nichols said. Their lungs were too damaged to be used for transplantation, but they did have some healthy tissue. They took one of the lungs and stripped away nearly everything, leaving a scaffolding of collagen and elastin. The scientists then took cells from the other lung and put them on the scaffolding. They immersed the structure in a large chamber filled with a liquid "resembling Kool-Aid," Nichols said, which provided nutrients for the cells to grow. After about four weeks, an engineered human lung emerged. Repeating the process, they created another lung from two other children who'd died. The lab-made lungs look very much like the real thing, Nichols says, just pinker, softer and less dense. Nichols said she thinks it will be another 12 years or so until they'll be ready to try using these lungs for transplants. "My students will be doing the work when I'm old and retired and can't hold a pipette anymore," she said. Before researchers experiment on humans, they'll try out lab-made lungs on pigs, she said. Doctors have already had success transplanting patients with synthetic tracheas. The first procedure was done in 2011, and since then, six more have been done. Two of the patients have died of causes unrelated to their tracheas, said David Green, CEO of Harvard Apparatus Regenerative Technology, which makes equipment used to make engineered body parts. |

Monkey Avatar. Seriously you guys... Monkey Avatar...
And this is just the stuff we admit to..... Master monkey's brain controls sedated 'avatar' The brain of one monkey has been used to control the movements of another, "avatar", monkey, US scientists report. Brain scans read the master monkey's mind and were used to electrically stimulate the avatar's spinal cord, resulting in controlled movement. The team hope the method can be refined to allow paralysed people to regain control of their own body. The findings, published in Nature Communications, have been described as "a key step forward". Damage to the spinal cord can stop the flow of information from the brain to the body, leaving people unable to walk or feed themselves. The researchers are aiming to bridge the damage with machinery. Match electrical activity The scientists at Harvard Medical School said they could not justify paralysing a monkey. Instead, two were used - a master monkey and a sedated avatar. The master had a brain chip implanted that could monitor the activity of up to 100 neurons. During training, the physical actions of the monkey were matched up with the patterns of electrical activity in the neurons. The avatar had 36 electrodes implanted in the spinal cord and tests were performed to see how stimulating different combinations of electrodes affected movement. The two monkeys were then hooked up so that the brain scans in one controlled movements in real time in the other. The sedated avatar held a joystick, while the master had to think about moving a cursor up or down. In 98% of tests, the master could correctly control the avatar's arm. One of the researchers, Dr Ziv Williams, told the BBC: "The goal is to take people with brain stem or spinal cord paralysis and bypass the injury. "The hope is ultimately to get completely natural movement, I think it's theoretically possible, but it will require an exponential additional effort to get to that point." He said that giving paralysed people even a small amount of movement could dramatically alter their quality of life. Reality or science fiction? The idea of one brain controlling an avatar body is the stuff of blockbuster Hollywood movies. However, Prof Christopher James, of the University of Warwick, dismissed a future of controlling other people's bodies by thought. He said: "Some people may be concerned this might mean someone taking over control of someone else's body, but the risk of this is a no-brainer. "Whilst the control of limbs is sophisticated, it is still rather crude overall, plus of course in an able-bodied person their own control over their limbs remains anyway, so no-one is going to control anyone else's body against their wishes any time soon." Instead, he said this was "very important research" with "profound" implications "especially for controlling limbs in spinal cord injury, or controlling prosthetic limbs with limb amputees". Realising that goal will face additional challenges. Moving a cursor up and down is a long way from the dextrous movement needed to drink from a cup. There are also differences in the muscles of people after paralysis; they tend to become more rigid. And fluctuating blood pressure may make restoring control more challenging. Prof Bernard Conway, head of biomedical engineering at the University of Strathclyde, said: "The work is a key step forward that demonstrates the potential of brain machine interfaces to be used in restoring purposeful movement to people affected by paralysis. "However, significant work still remains to be done before this technology will be able to be offered to the people who need it." |
A new and daring cosmological model of the universe from a university in Taiwan describes the universe without a big bang – an eternal universe with NO beginning and NO end. This new and insane model for the universe is actually crazier than it sounds, so bear with me here while we delve into details.
Professor Wun-Yi Shu (from the National Tsing Hua University), has completely veered off of traditional cosmological thinking by proposing a universe that hypothetically explains our observations better than the current models. Shu means to do away with dark energy altogether, while at the same time explaining the acceleration of the universe more precisely. Shu proposes this model to answer some of the most puzzling questions in cosmology, such as the flatness problem (a problem pertaining to cosmological fine-tuning), and the horizon problem (which deals with the uneven temperatures in the universe) – all in one encompassing new model. http://www.fromquarkstoquasars.com/w...rd-225x300.png Shu’s cosmology includes a sweeping change of our understanding of the universe. Space, time, mass, and length can all be converted between themselves. The speed of light and the gravitational constant are both variable. Time has no beginning or end (neither a big bang nor a big crunch singularity). The universe is a sphere instead of being flat (a higher-dimensional analogue of a sphere called a 3-sphere) and other seemingly bizarre concepts. At some point in the universe’s history, time converts into space, while mass converts into length. Conversely, the opposite also at some point holds true. Length converts to mass and the universe contracts – eventually causing the conversion to take place again procuring another inflation/expansion event. Shu argues that the big bang cosmological model does not adequately explain the expansion of the universe; thus forcing scientists to propose the existence of things such as dark energy to help fill the voids in our knowledge. According to the tests he has run using observations of Type Ia supernovae, his model of cosmology is a much better match for the available data. The nature of Shu’s cosmological model eliminates problems facing the big bang event because this model simply does not have one. Furthermore, the 3-sphere nature of Shu’s universe automatically eliminates the flatness and horizon problems – although I would be neglectful if I failed to mention that inflation has (for the most part), solved both of these problems. Shu’s ‘steady state’ model of the universe has been published on ArXiv for review from his peers (although ArXiv itself is not a peer reviewed journal). Pending review, Shu’s model might gain some credence– or it will simply remain as an interesting (albeit insane) artifact of mathematics |

I suspect this higher dimensional theory captures the different relationships that the parts of existence may have in a multidimentional universe but does not embed the particular relationship of our specific universe. It is sort of like tying a knot. There are all kinds of knots and this new theory expresses the relationships of knots in general but the specific steps and the "knot" that results is our universe is not specified. |

I think in this same Science thread is an article about leaving Feynman's diagrams behind (which try to model individual paths and are nice in simple systems) and go with a higher dimensional geometry that reflects the energy time result and gives us a simpler look at the final answer because there are both restricted states going in and out of a system Quantum Mechanically. You don't get bogged down in the details of trying to follow an ever larger accounting of possibilities to sum to the result. So there are higher dimensional systems that can give us an answer in general questions. And the trick is to knit together well behaved manifolds where each of the parts are well behaved and additionally representative of different physical parts of the system under investigation. I am sure this is what this Physicist has done. The whole 10 and 11 dimensional space and Penrose and his parts in discussing reality all use similar approaches. The inverse deSitter spaces and other inventive well behaved vector spaces or better yet Clifford spaces are being mathematically developed and tried in looking at a multidimensional explanation. (Even in computer games we see 5 dimensional systems with one of the axis set at infinity to be a projective geometry that facilitates following extended relationships lost in three dimensions say when something goes behind a building in line of sight in three dimensions.) The problem is these processes is they need real results as predictions of behavior of some momentum involved items because that is what we really detect in this world in order to be substantiated as reflective of our particular universe. |

Tiny Crystal Is Oldest Known Piece of Earth, Scientists Say
http://www.nbcnews.com/science/scien...sts-say-n36916 Scientists using two different age-determining techniques have shown that a tiny zircon crystal found on a sheep ranch in western Australia is the oldest known piece of our planet, dating to 4.4 billion years ago. Writing in the journal Nature Geoscience on Sunday, the researchers said the discovery indicates that Earth's crust formed relatively soon after the planet formed and that the little gem was a remnant of it. John Valley, a University of Wisconsin geoscience professor who led the research, said the findings suggest that the early Earth was not as harsh a place as many scientists have thought. To determine the age of the zircon fragment, the scientists first used a widely accepted dating technique based on determining the radioactive decay of uranium to lead in a mineral sample. But because some scientists hypothesized that this technique might give a false date due to possible movement of lead atoms within the crystal over time, the researchers turned to a second sophisticated method to verify the finding. They used a technique known as atom-probe tomography that was able to identify individual atoms of lead in the crystal and determine their mass, and confirmed that the zircon was indeed 4.4 billion years old. To put that age in perspective, the Earth itself formed 4.5 billion years ago as a ball of molten rock, meaning that its crust formed relatively soon thereafter, 100 million years later. The age of the crystal also means that the crust appeared just 160 million years after the very formation of the solar system. The finding supports the notion of a "cool early Earth" where temperatures were low enough to sustain oceans, and perhaps life, earlier than previously thought, Valley said. The zircon was extracted in 2001 from a rock outcrop in Australia's Jack Hills region. For a rock of such importance, it is rather small. It measures only about 200 by 400 microns, about twice the diameter of a human hair. http://media2.s-nbcnews.com/j/newscm...ux-720-600.jpg |

Watch a Car-Sized Asteroid Slam Into the Moon by NANCY ATKINSON on FEBRUARY 24, 2014 Hey, all you astro-photographers/videographers out there: were you shooting the Moon back on September 11, 2013? You may want to review your footage and see if you captured a bright flash which occurred at about 20:07 GMT. Astronomers say a meteorite with the mass of a small car slammed into the Moon at that time and the impact produced a bright flash, and it even would have been easy to spot from the Earth. According to astronomers Jose M. Madiedo, from the University of Huelva and Jose L. Ortiz, from the Institute of Astrophysics of Andalusia both in Spain, this impact was the longest and brightest confirmed lunar impact flash ever observed, as the “afterglow” of the impact remained visible for 8 seconds.

I'm not convinced that Hawking can do anything other than drool at this point. I saw a History or Discovery Channel show on the guy and he can't even type into his voice machine anymore. Anything Hawking "says" has to be pre-programmed into the voice box prior to an appearance.
He has a full-time theoretical physicist guy that hangs out with him all the time that supposedly interprets his grunts and eye movements to figure out what he's trying to say. So I'm guessing any new theory he puts forth is largely the assistant's theory with Hawking's name attached to give it some kind of weight. |
Quote:
He hasn't typed into a voice machine in well over a decade. He's been using a system that interprets a range of small facial movements. He does program entire presentations sentence by sentence. But any interpretations are done by his complex hardware/software setup custom made from Intel, and not his personal assistant translating grunts. His new theory is absolutely his own, and to suggest otherwise is crazy. I'm really surprised you would suggest that. |

And I'm just going by what the show (which I watched a few years ago) showed in real time. His assistant was writing equations on a board and he was literally trying to translate grunts and eye movement to determine if he had it right, or where he had it wrong. |

Besides that, the idea that he, or his assistant, or the scientific community in general, would allow his assistant to to pass off work under Hawking's name is just crazy for many reasons. |

Quote:
I checked and you are correct, as of 2013 he could get "UP TO" 10 words a minute. I haven't seen it happen. All we see are the pre-programmed sentences. But 10 words a minute sounds excruciating. As far as the "he, or his assistant, or the scientific community in general" not allowing something like that to happen. Well, lets address those one by one. He really can't talk, so it's easy enough to keep him silent. The scientific community in general really doesn't have a hell of a lot more access to Hawking personally than you or I, so they can be bamboozled, and I don't believe they are quite as incorruptible as you do. That leaves the assistant. And I can think of several scenarios where he might benefit, not the least of which is financially. I'm not saying any of that is the case. Just saying that I am not convinced everything is as they say. |
Quote:
<iframe width="560" height="315" src="//www.youtube.com/embed/UxojnylOalM" frameborder="0" allowfullscreen></iframe> There's plenty more recent interview videos and such available. I think it's approaching impossible that Hawking's personal assistant could pass off work for Hawking, either with or without Hawking's permission, or that the rest of the world could be bamboozled as such. |
So Hawking would allow himself to be tried out to present someone else's work as his own even if he disagrees with it? That's ****ing crazy. He's not a prisoner. If he wanted to say "hey, this ain't my work, I don't approve of this theory", he would.

And I readily admit, that notion is pure conspiracy theory. But it isn't impossible.

It really can't be any other way when the guy speaks, at most, 10 words a minute. |
Dude. He had nothing but time in his mind. He had more time to think about these things than literally anyone. Communicating his theory is the easy part.

Quote:
Several years ago, some other astrophysicists came up with the black hole firewall paradox, which says quantum mechanics actually can be applied to black holes if the event horizon acts like a firewall. But that theory violated Einstein's relativity. Hawking then produced his new theory, which actually satisfies both quantum mechanics and the theory of relativity at the same time, by removing the event horizon altogether and instead defining an "Apparent horizon". He's been of the belief that information is shared since the 70s, when he theorized "Hawking radiation". That was the whole point of his Hawking radiation idea. I'm just not understanding why he would be mad at anything. |
