Submission + - Are gut microbes making you fat? (newsweek.com)

Stonent1 writes: "A recent Newsweek article explains how some scientists have linked body weight to the quantity and type of bacteria in your digestive system and that in experiments in mice they can alter the weight of the mouse by transferring certain bacteria to their digestive system. It is hypothesized that some bacteria are more efficient at converting what you eat into what your body can use for energy and in those cases you would gain weight more easily. Conversely, people who are more slim have a greater abundance of less efficient bacteria so the body is not able to make use of all the food coming in. If further studies support this data, we may at some time be able to alter the balance with dietary supplements."

Submission + - Eat, Drink, and be Monitored

Reservoir Hill writes: "A new restaurant has opened on the leafy campus of Wageningen University in the Netherlands, fitted with a control center and two dozen hidden cameras devoted to exploring the question of what makes people eat and drink the way they do. Over the next 10 years, a team of more than 20 scientists will use the research facility to watch how people walk through the restaurant, what food catches their eye, whether they always sit at the same table and how much food they throw away. Researchers will examine environmental influences on eating behavior by making small changes in the color of the lights, in accompanying sounds, in the scents or the furniture. "We want to find out what influences people: colors, taste, personnel," said one researcher. "This restaurant is a playground of possibilities. We can ask the staff to be less friendly and visible or the reverse." University staff who want to eat at the new restaurant will have to sign a consent form agreeing to be watched."

Submission + - The faithiness of science (nytimes.com)

mlimber writes: The New York Times is running a provocative piece on the faith-based nature of science: "The problem with this neat separation into 'non-overlapping magisteria,' as Stephen Jay Gould described science and religion, is that science has its own faith-based belief system. All science proceeds on the assumption that nature is ordered in a rational and intelligible way.... [B]oth religion and science are founded on faith — namely, on belief in the existence of something outside the universe, like an unexplained God or an unexplained set of physical laws, maybe even a huge ensemble of unseen universes, too. For that reason, both monotheistic religion and orthodox science fail to provide a complete account of physical existence.... [U]ntil science comes up with a testable theory of the laws of the universe, its claim to be free of faith is manifestly bogus."

Submission + - NYTimes Editorial Says Science Is a Religion (nytimes.com) 1

jeffporcaro writes: Paul Davies writes a guest editorial in the NYTimes (sorry, but that's where it is) in which he shares his opinion that science is no better/no different than religion, since it forces its adherents to take items on faith. Examples he gives of faith-based science include our belief that the laws of physics will not change tomorrow and the idea that there are multiple universes — both are non-falsifiable and therefore no better than religious faith. Similarly, the fact that fundamental concepts are not fully explained (Why are the laws that regulate motion the way that they are? Who/what made them that way?) proves to him that science is based on a faulty, "deeply anti-rational" foundation. See here for full story.

Submission + - Medical Breakthrough, Skin Cells to Stem Cells (physorg.com)

eldavojohn writes: "A simultaneous discovery in both Japan and Wisconsin has revealed the possibility of transforming skin cells to stem cells which both eliminates the risk of rejection from the patient to be treated with them and also clears up any ethical problems of using embryonic stem cells. This is being heralded as a monumental breakthrough by the community and may "rapidly advance research in the treatment of cancer, Alzheimer's and Parkinson's diseases, diabetes, arthritis, spinal cord injuries, strokes, burns and heart disease because scientists will have much greater access to stem cells." Good news for all."

Submission + - Microsoft working on "executable biology"

holy_calamity writes: Microsoft Research think they can straighten out biologists by making them think like coders. Struggles with large datasets like the human genome are reduced if you structure models like computer programs, representing components like proteins or genes as subroutines, they say. A full PDF of the Nature paper is here. A new 'executable biology' research group is being set up.

Submission + - Vote to Eliminate Leap Seconds 6

Mortimer.CA writes: As mentionted on Slahdot previously, there is a proposal to remove leap seconds from UTC (nee 'Greenwich' time). It wil be put to a vote to ITU member states, and if 70% agree, the leap second will be eliminated by 2013. There is some debate as to whether this change is a good or bad idea. One philosophical point opponents make is that the 'official' time on Earth should match the time of the sun and heavens. People with appliances that blink '12:00' can probably ignore this issue.

Submission + - The Muddy Waters of Taser Safety

SoyChemist writes: Many scientists have asked the question: Can Tasers kill people? Yet, the waters surrounding the less lethal weapon remain very murky. The Wired Science Blog has a compilation of some of the more spectacular safety studies. They include case reports of a dart penetrating the skull of a young man, a pacemaker logging cardiac data when an old man was zapped, and conclusions drawn from seventy-five separate investigations. This follows an earlier report in New Scientist which showed that some of the safety studies were funded by Taser International.

Submission + - Peer-to-peer is good for music sales (in Canada): (ic.gc.ca)

xplinuxmac writes: A study about the positive effects of p2p music downloads: Industry Canada undertook a music file sharing study during 2006-07 to measure the extent to which music downloads over peer-to-peer file sharing networks, for which the sound recording industry receives no remuneration, affect music purchasing activity in Canada. The data used for this analysis are from a Decima Research survey conducted between April and June, 2006, on behalf of Industry Canada. The report, prepared by University of London researchers, Birgitte Andersen and Marion Frenz, found that music downloads have a positive effect on music purchases among Canadian downloaders but that there is no effect taken over the entire population aged 15 and over.

Submission + - Ham Radio Operator Finds Cure For Cancer (latimes.com) 5

CirReal writes: "John Kanzius, K3TUP, himself suffering from cancer with nine months to live, used nanotechnology and a radio transmitter to kill cancer cells. "Kanzius did not have a medical background, not even a bachelor's degree, but he knew radios. He had built and fixed them since he was a child, collecting transmitters, transceivers, antennas and amplifiers, earning an amateur radio operator license. Kanzius knew how to send radio wave signals around the world. If he could transmit them into cancer cells, he wondered, could he then direct the radio waves to destroy tumors, while leaving healthy cells intact?" Reseachers "recently killed 100% of cancer cells grown in the livers of rabbits, using Kanzius' method.""

Submission + - Your Brain Knows More than You Do

Hugh Pickens writes: "Have you even "known" something was true that later turned out to be mistaken? Our memories are not always trustworthy but recent research shows that vivid false memories that may seem indistinguishable from true memories may be processed by different parts of the brain. Using an MRI, the study showed (pdf) that when participants had confidence in their answer and they were correct, blood flow increased to the medial temporal lobes containing the hippocampus, important for memory. When subjects had confidence in their answer but were wrong, the frontoparietal region lit up, a region of the brain associated with a "sense of familiarity." The research could one day be used to devise an early test for Alzheimer's disease, or to assess the accuracy of witness testimony and underscores the fact that judges and juries should not use a witness's confidence in their own answers as a signal that the answers are more likely to be true. "It is really surprising, but there is a very weak relation between accuracy and confidence," says Valerie Reyna, a cognitive neuroscientist at Cornell University."

Submission + - Intergalatic Clouds of Missing Mass Missing Again

Ponca City, We Love You writes: "Researchers at the University Of Alabama In Huntsville have discovered that some x-rays thought to come from intergalactic clouds of "warm" gas are instead probably caused by lightweight electrons leaving the mass of the universe as much as ten to 20 percent lighter than previously calculated. In 2002 the same team reported finding large amounts of extra "soft" (relatively low-energy) x-rays coming from the vast space in the middle of galaxy clusters. Their cumulative mass was thought to account for as much as ten percent of the mass and gravity needed to hold together galaxies, galaxy clusters and perhaps the universe itself. When the team looked at data from a galaxy cluster in the southern sky, however, they found that energy from those additional soft x-rays doesn't look like it should. "The best, most logical explanation seems to be that a large fraction of the energy comes from electrons smashing into photons instead of from warm atoms and ions, which would have recognizable spectral emission lines," said Dr. Max Bonamente."
