Individuals that are able to blend in to their surroundings and avoid being eaten are able to survive longer, reproduce, and thus increase their fitness (pass along their genes to the next generation) compared to those who stand out more. This may seem like a good strategy, and fairly common in the animal kingdom, but who ever heard of a plant doing the same thing? http://www.physorg.com/news178382633.html Biology Wed, 25 Nov 2009 14:44:31 EST news178382633 (PhysOrg.com) -- A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week in the journal Science Translational Medicine. http://www.physorg.com/news178382282.html Medicine & Health Wed, 25 Nov 2009 14:38:42 EST news178382282 Imagine the Earth's crust as the planet's skin: Some areas are old and wrinkled while others have a fresher, more youthful sheen, as if they had been regularly lathered with lotion. http://www.physorg.com/news178381626.html Space & Earth Wed, 25 Nov 2009 14:27:50 EST news178381626 (PhysOrg.com) -- Peering through the thick dust clouds of our galaxy's "bulge" (the myriads of stars surrounding its center), a team of astronomers has unveiled an unusual mix of stars in the stellar grouping known as Terzan 5. Never observed anywhere in the bulge before, this peculiar "cocktail" of stars suggests that Terzan 5 is in fact one of the bulge's primordial building blocks, most likely the relic of a dwarf galaxy that merged with the Milky Way during its very early days. http://www.physorg.com/news178377940.html Space & Earth Wed, 25 Nov 2009 13:28:26 EST news178377940 Photosynthetic organisms need to cope with a wide range of light intensities, which can change over timescales of seconds to minutes. Too much light can damage the photosynthetic machinery and cause cell death. Scientists at the Carnegie Institution were part of a team that found that specific proteins in algae can act as a safety valve to dissipate excess absorbed light energy before it can wreak havoc in cells. http://www.physorg.com/news178378035.html Biology Wed, 25 Nov 2009 13:28:05 EST news178378035 When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered. http://www.physorg.com/news178377237.html Biology Wed, 25 Nov 2009 13:14:44 EST news178377237 Scientists at the California Institute of Technology have uncovered evidence of a primitive emotion-like behavior in the fruit fly, Drosophila melanogaster. Their findings, which may be relevant to the relationship between the neurotransmitter dopamine and attention deficit hyperactivity disorder (ADHD), are described in the December issue of the journal Neuron. http://www.physorg.com/news178375764.html Medicine & Health Wed, 25 Nov 2009 13:01:02 EST news178375764 (AP) -- The European Parliament has endorsed new telecom rules that would give phone and Internet users more rights and allow them to appeal to national courts if they are cut off for illegal file-sharing. http://www.physorg.com/news178374890.html Technology Wed, 25 Nov 2009 12:50:02 EST news178374890 Bacteria don't have easy lives. In addition to mammalian immune systems that besiege the bugs, they have natural enemies called bacteriophages, viruses that kill half the bacteria on Earth every two days. http://www.physorg.com/news178375259.html Biology Wed, 25 Nov 2009 12:42:43 EST news178375259 Breathing carbon dioxide can trigger panic attacks, but the biological reason for this effect has not been understood. A new study by University of Iowa researchers shows that carbon dioxide increases brain acidity, which in turn activates a brain protein that plays an important role in fear and anxiety behavior. http://www.physorg.com/news178374999.html Medicine & Health Wed, 25 Nov 2009 12:37:43 EST news178374999 (PhysOrg.com) -- You wouldn't want a car with no brakes.

Their experiments in mice revealed that the daily waxing and waning of thousands of genes in the liver -- the body's metabolic clearinghouse -- is mostly controlled by food intake and not by the body's circadian clock as conventional wisdom had it. http://www.physorg.com/news178369757.html Medicine & Health Wed, 25 Nov 2009 11:09:50 EST news178369757 (PhysOrg.com) -- Several research security firms have reported a new worm attack against jail broken iPhones, dubbed "Ikee.B or "Duh", this worm searches for personal and banking information. http://www.physorg.com/news178368713.html Electronics Wed, 25 Nov 2009 10:52:39 EST news178368713 (PhysOrg.com) -- Research into Alzheimer's disease seems an unlikely approach to yield a better way to fight urinary tract infections (UTIs), but that's what scientists at Washington University School of Medicine in St. Louis and elsewhere recently reported. http://www.physorg.com/news178359416.html Chemistry Wed, 25 Nov 2009 09:20:01 EST news178359416 (PhysOrg.com) -- A new study of adults aged 70 or older found that increased servings of fruits and vegetables were significantly associated with a decrease of cognitive impairment, and that those eating three or more servings of vegetables per day had a 30 percent lower risk of death from heart disease. http://www.physorg.com/news178358737.html Medicine & Health Wed, 25 Nov 2009 08:50:02 EST news178358737 (PhysOrg.com) -- A British team hoping to be the first to get a car to 1,000 mph (1,610 km/h) has made its final design selection.

The paper he submitted described a novel analytical technique that we today call the Fourier transform, and it won the competition; but the prize jury declined to publish it, criticizing the sloppiness of Fourier`s reasoning. According to Jean-Pierre Kahane, a French mathematician and current member of the academy, as late as the early 1970s, Fourier`s name still didn`t turn up in the major French encyclopedia the Encyclopędia Universalis. http://www.physorg.com/news178356724.html Other Sciences Wed, 25 Nov 2009 07:35:16 EST news178356724 (PhysOrg.com) -- Cambridge researchers have identified a group of traders consistently able to outperform the market, even during the credit crisis. http://www.physorg.com/news178349551.html Other Sciences Wed, 25 Nov 2009 07:28:40 EST news178349551 (PhysOrg.com) -- Functional Magnetic Resonance Imaging (fMRI) scans have been used, possibly for the first time, in the sentencing phase of a murder trial in Chicago in the US. http://www.physorg.com/news178354644.html Medicine & Health Wed, 25 Nov 2009 06:58:10 EST news178354644 Australia's venomous redback spiders are on the march in Japan, where they are believed to have arrived years ago as stowaways on cargo ships, a wildlife expert warned Wednesday. http://www.physorg.com/news178349649.html Biology Wed, 25 Nov 2009 05:50:01 EST news178349649
