AnonymousHack writes "New Scientist examines why people are in general more rude and abusive online. 'Psychologically, we are "distant" from the person we're talking to and less focused on our own identity. As a result we're more prone to aggressive behavior' says one psychologist, who also cites research showing messages received by email are always perceived more negatively than on the phone."

  dprovine writes "According to a joint investigation by The Washington Post and 60 Minutes, a forensic test used by the FBI for decades is known to be invalid. The National Academy of Science issued a report in 2004 that FBI investigators had given "problematic" testimony to juries. The FBI later stopped using "bullet lead analysis", but sent a letter to law enforcement officials saying that they still fully supported the science behind it. Hundreds of criminal defendants — some already convicted in part on the testimony of FBI experts — were not informed about the problems with the evidence used against them in court."Read more of this storyat Slashdot.

  Mortimer.CA writes "As discussed on Slashdot previously, there is a proposal to remove leap seconds from UTC (nee 'Greenwich' time). It will be put to a vote to ITU member states during 2008, 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. The proposal calls for a 'leap-hour' in about 600 years, which nobody seems to believe is a good idea. One philosophical point opponents make is that the 'official' time on Earth should match the time of the sun and heavens."Read more of this storyat Slashdot.

  h.ross.perot informs us of research out of the California Pacific Medical Center Research Institute suggesting that a compound found in cannabis may stop breast cancer from metastasizing. Cannabidiol, or CBD, could develop into a non-toxic alternative to chemotherapy some years down the road, if animal and human trials bear out its effectiveness. The article notes that smoking cannabis will not deliver significant quantities of CBD.Read more of this storyat Slashdot.

  pickens writes "In recent years scientists have begun to view the existence of life outside of our solar system as ever-more likely. If life does emerge readily under terrestrial conditions, then perhaps it formed many times on our home planet. To pursue this tantalizing possibility, scientists have begun searching deserts, lakes and caverns for evidence of earth-bound 'alien' life-forms, organisms that would differ fundamentally from all known living creatures because they arose independently. Microbes have already been found inhabiting extreme environments ranging from scalding volcanic vents to the dry valleys of Antarctica. Other so-called extremophiles can survive in salt-saturated lakes, highly acidic mine tailings contaminated with metals,and the waste pools of nuclear reactors. Although 'alien' microbes might look like ordinary bacteria, their biochemistry could involve exotic amino acids or different elemental building blocks so researchers are devising tests to identify exotic microbes. If shadow life is confined to the microbial realm, it is entirely possible that scientists have overlooked it."Read more of this storyat Slashdot.

  An anonymous reader writes "An award-winning science author, Gary Taubes, has written a book that pans the medical community's treatment of the obesity epidemic. What is interesting is that it looks like the medical community is behaving in a very unscientific manner. Taubes points out that the current medical orthodoxy — that consuming fat makes you fat and exercise makes you thin — has no basis in research. In fact, all the available research points in quite another, and more traditional, direction. Here's the (excellent) podcast of an interview with Taubes on CBC's 'Quirks and Quarks.' So, has medicine become a non-science? Is it mostly a non-science? Somewhat?"Read more of this storyat Slashdot.

  MikShapi writes "Skin cells can now be turned into something resembling stem cells. A genetic modification to four genes using a viral vector reverses differentiating, making the cells revert to a stem-cell state, capable for becoming any other cell in the body. The researchers are calling them 'iPS cells' or 'induced pluripotent stem cells.' In their experiments, iPS cells in the lab turned into nerve cells, heart muscle, and other tissues. The research was published in Cell and Nature by teams from the universities of Kyoto and Wisconsin. The article notes that if the new method proves successful, 'we can disconnect the whole stem cell debate from the culture war, from battles over embryo politics and abortion rights.' And, should this technique be adopted, stem cells will henceforth be abundant, easier and cheaper to come by for research and therapeutic purposes."Read more of this storyat Slashdot.

  hereisnowhy writes "A giant fossilized claw discovered in Germany belonged to an ancient sea scorpion that was much bigger than the average man, an international team of geologists and archaeologists reported Tuesday. In a report in the Royal Society's journal Biology Letters, the team said the claw indicates that sea scorpion Jaekelopterus rhenania was almost 2.5 meters long, making it the largest arthropod — an animal with a segmented body, jointed limbs and a hard exoskeleton — ever found. In the report, the authors said the scorpion exceeds previous size records for arthropods by almost half a meter."Read more of this storyat Slashdot.

  An anonymous reader noted that "The Arecibo Observatory funding was slashed. Cut to $8 million from $10.5 million, which will decrease the amount of time that the telescope is operational. "A quarter of its staff was laid off last year," and Arecibo, which is located in Puerto Rico, could possibly be completely closed in four years, according to the "National Science Foundation (NSF), which pays for the operation of the telescope." This comes after "a review panel for the foundation's astronomy division two years ago" suggested cutting Arecibo's financing by 25 percent as a way to pay for new facilities. There has been "[a]n outcry" in response to the "decision, particularly from planetary scientists" who argued that the panel "overlooked Arecibo's role in cataloging potential dangers from asteroids." The Times notes that in Arecibo's favor is the fact that it "may be much cheaper to keep...open" than dismantle, which "could cost hundreds of millions of dollars."" I've been considering a vacation to PR for a few years, and seeing this thing is on my list of awesome things to try to see. Guess I should hurry ;)Read more of this storyat Slashdot.

  coondoggie writes to tell us that NASA has announced a new low-cost satellite that could be ideal for those who wish to get into space quickly and (relatively) inexpensively. "The Fast, Affordable, Science and Technology SATellite (FASTSAT) is 39.5 inches in diameter — not much larger than an exercise ball. It is hexagonally shaped and clocks in at a little less than 200 Lbs. It can carry a payload up to 110 Lbs. [...] NASA said FASTSAT is just the right size for earth observing missions, space science missions, and technology demonstrations. 'We think we can do whole missions for less than $10 million instead of the traditional $100s of millions, and that includes the launch vehicle, the satellite, and the widget you want to test,' said Marshall Space Flight Center's Edward 'Sandy' Montgomery in a release."Read more of this storyat Slashdot.

'By the time the Earth's moon formed, when the Sun was 30 million years old, the planet formation process in our Solar System should have been approaching its end. In the latest study, Dr Gorlova's team looked at the heat signature of stars using the infrared. This allows astronomers to predict how much of that heat comes from the star itself and how much is re-emitted by dusty material encircling it.'"Read more of this storyat Slashdot.
