Science: HIV/AIDS Vaccine To Begin Phase I Human Trials on Thursday July 02, @03:21PM
An anonymous reader writes "An HIV/AIDS vaccine developed in Ontario has applied for Phase 1 human trials. Safety and immunogenicity studies of the vaccine, dubbed SAV001-H, have already been completed on animals. Phase 1 human trials will check the safety of the vaccine on HIV positive volunteers. Phase 2 will then test immunogenicity."

Science: Computer Reveals Stone Tablet "Handwriting" on Thursday July 02, @02:41PM
ewenc writes "A computer technique can tell the difference between ancient Greek inscriptions created by different artisans, a feat that ordinarily consumes years of human scholarship, reports New Scientist. A team of Greek computer scientists created the program after a scholar challenged them to attribute 24 inscriptions to their rightful cutter. The researchers scanned the tablets and constructed an average shape for several Greek letters in every tablet. After comparing the average letters between different tablets, they correctly attributed the inscriptions to six stone-cutters."

Science: Japanese Creating "Super Tuna" on Thursday July 02, @01:41PM
motherpusbucket writes "The Telegraph reports that Japanese scientists hope to be breeding a so-called 'Super Tuna' within the next decade or so. They have about 60% of the genome mapped and expect to finish it in the next couple months. The new breed will grow faster, taste good, have resistance to disease and will totally kick your ass if you cross them."

Science: FDA Considers Banning Acetaminophen-Based Pain Killers on Thursday July 02, @12:57PM
Greg George writes "The FDA has determined that Tylenol enhancing pain killers are dangerous enough to potentially be pulled from the market. Drugs including Vicodin, Hydrocodone, Lortab, Maxidone, Norco, Zydone, Tylenol with codeine, Percocet, Endocet, and Darvocet may be permanently banned from the US market, even if the patient has a prescription from a doctor. The problem is the key ingredient — acetaminophen — can easily damage or destroy a patient's liver if more than 2000 mg are used per day. In many cases that means if you take a pain killer and then take two extra strength Tylenol, you may have gone over the maximum dosage per day."

Oracle Goddess writes "According to the US National Institute for Mental Health in Bethesda, Maryland, scientists have discovered a remarkable similarity between the genetic faults behind both schizophrenia and manic depression in a breakthrough that is expected to open the way to new treatments for two of the most common mental illnesses, affecting millions of people. Previously schizophrenia and depression were assumed to be two separate conditions, but the new research shows for the first time that both have a common genetic basis that leads people to develop one or the other of the two illnesses."

destinyland writes "'We're going to have to do extensive robotic exploration,' says the director of NASA's Ames Research Center, suggesting nanotechnology to build self-replicating robots on Mars. Genetically engineering extraction and construction microbes could 'grow' electrical components, and eventually convert carbon dioxide on Mars into oxygen. 'If we really want to settle Mars, and we don't want to have to carry millions of tons of equipment with us to duplicate the way we live on Earth, these technologies will be key.' This interview with Peter Worden, the director of NASA's Ames Research Center, was just featured in the summer issue of H+ magazine, and he also argues that robots will be necessary to first survey Mars for underground microbes and protect the unique Martian biosphere, since it may contain clues about earth's own first life forms. In fact, given the water and carbon that's been discovered on Mars, the possibility of underground microbes is still considered real, and Worden argues that Mars 'may already be supporting life.'"

Science: Comets Probably Seeded Earth's Nitrogen Atmosphere on Wednesday July 01, @11:58PM

KentuckyFC writes "One of the biggest puzzles of astrobiology is the origin of the Earth's oceans and atmosphere. One favored theory is that our water is the leftovers from a bombardment of comets early in Earth's history. But the ratio of hydrogen and deuterium in the oceans doesn't match the ratio in the four comets measured so far (Halley's, Hyakutake, Hale-Bopp and C/2002 T7 LINEAR). Now a new analysis of the ratio of nitrogen-14 and 15 isotopes in these comets and on Earth places new limits on how much of our environment could have come from comets. On the one hand, the astronomers who did the work say that no more than a few percent of Earth's water could have come from comets. But on the other, they say that the ratio of nitrogen isotopes in these comets almost exactly matches the ratio in Earth's atmosphere. That suggests that while Earth's oceans must have come from somewhere else, Earth's early atmosphere was probably seeded by comets."

Deag writes "A mega colony of one family of ants has spread all over the world. Previous mega colonies in California, Europe and Japan have been shown to be in fact one global colony.
Ants from the smaller super-colonies were always aggressive to one another. So ants from the west coast of Japan fought their rivals from Kobe, while ants from the European super-colony didn't get on with those from the Iberian colony.
But whenever ants from the main European and Californian super-colonies and those from the largest colony in Japan came into contact, they acted as if they were old friends."

mmmscience writes "While fertility studies lately seem to have been exclusively focused on in vitro fertilization [IVF], new data coming out of Australia may help with unaided successful conceptions. The study has found that men who have ejaculate daily produce sperm with less damaged DNA. While such actions decrease sperm concentration, it does increase motility, meaning healthier sperm have a better chance of making it all the way to the egg. Good news, as another report has found severe chromosome abnormalities in over 90% of IVF eggs, meaning artificial insemination is just now discovering a whole new field of problems."

Urchin writes "The quality of sunlight varies depending on where you live, but off-the-shelf solar cells are all identical. A new solar cell designed by UK firm Quantasol is easily tuned to adapt to the local light conditions, which boosts its long-term performance. Its short-term performance isn't bad though — the single junction solar cell has a peak efficiency greater than any previous device, beating a world record that's stood for 21 years."
