First clear evidence of organized feasting by early humans
http://feeds.sciencedaily.com/~r/sciencedaily/~3/c9olVNk4aGo/100830152526.htm
Community feasting is one of the most universal and important social behaviors found among humans. Now, scientists have found the earliest clear evidence of organized feasting, from a burial site dated about 12,000 years ago. These remains represent the first archaeological verification that human feasting began before the advent of agriculture.

Researchers develop new laboratory cell lines to study treatment for anaplastic thyroid cancer
http://feeds.sciencedaily.com/~r/sciencedaily/~3/18vkO4WtPP4/100825093251.htm
To their deep dismay, researchers discovered several years ago that laboratory samples of anaplastic thyroid cancer they were using to help them find new treatments for this lethal disease were probably some other kind of cancer. It quickly became evident that the situation in their lab was common throughout the world. Up to half of the cell lines that were supposed to originate from patients with this rare thyroid cancer were either colon or melanoma cancer. So, with the cooperation of many researchers nationwide, the researchers set out to create a new set of laboratory ATC cells, derived from tumors donated by patients.

Research produces tools to study stallions' subfertility
http://feeds.sciencedaily.com/~r/sciencedaily/~3/BSW4oJYeS9c/100826162015.htm
Subfertility of breeding stallions -- meaning the horses are less able to sire foals -- is a well-recognized problem that has caused multi-million-dollar losses in the equine industry, experts say. Researchers believe they are making progress in solving the problem by using an approach that might provide tools and resources necessary to study subfertility without causing stallions the angst of providing testicular samples for testing.

'Stocky dragon' dinosaur, relative of Velociraptor, terrorized Late Cretaceous Europe
http://feeds.sciencedaily.com/~r/sciencedaily/~3/JZxyi7XXnpY/100830152523.htm
Paleontologists have discovered that a close relative of Velociraptor hunted the dwarfed inhabitants of Late Cretaceous Europe, an island landscape largely isolated from nearby continents. While island animals tend to be smaller and more primitive than their continental cousins, the theropod Balaur bondoc was as large as its relatives on other parts of the globe and demonstrated advanced adaptations including fused bones and two terrifyingly large claws on each hind foot.

During field studies, scientists discovered that the oral secretions of tobacco hornworm larvae contain a particular substance that promptly alters a green leaf volatile in tobacco leaves into an odor attractant signal. With this signal, called (E)-2-hexenal, they unintentionally lure their own enemies: carnivorous bugs. These bugs start their piercing attacks not only against freshly hatched caterpillar babies; they also devour eggs laid by the female moths.

Experimental treatments for cocaine addiction may prevent relapse
http://feeds.sciencedaily.com/~r/sciencedaily/~3/bWc1T7lNhAI/100826141341.htm
The drug disulfiram, used for years to deter recovering alcoholics from drinking, also can treat cocaine addiction. Disulfiram prevents rats from seeking cocaine after a break, a model for addicts tempted to relapse. Disulfiram appears to work by inhibiting the enzyme dopamine beta-hydroxylase, which is required for the production of the neurotransmitter norepinephrine. A selective inhibitor of that enzyme, nepicastat, is also effective in the same model of cocaine relapse.

http://feeds.sciencedaily.com/~r/sciencedaily/~3/BpJi-St_eAE/100824110852.htm
A new study shows that male rats prenatally exposed to low doses of atrazine, a widely used herbicide, are more likely to develop prostate inflammation and to go through puberty later than non-exposed animals. The research adds to a growing body of literature on atrazine, an herbicide predominantly used to control weeds and grasses in crops such as corn and sugar cane. Atrazine and its byproducts are known to be relatively persistent in the environment, potentially finding their way into water supplies.

Proof that a gut-wrenching complaint -- irritable bowel syndrome -- is not in your head
http://feeds.sciencedaily.com/~r/sciencedaily/~3/7D2DzEYm7Tg/100819141950.htm
Irritable bowel syndrome makes life miserable for those affected, an estimated ten percent or more of the population. What further irritates many sufferers is that they often are labeled as hypochondriacs, since physical causes have never been identified -- until now. Biologists in Germany have discovered mini-inflammations in the mucosa of the gut, which upset the sensitive balance of the bowel and are accompanied by sensitization of the enteric nervous system.

New biological find gives consequences for doping offence
http://feeds.sciencedaily.com/~r/sciencedaily/~3/01rFUVvyLDY/100819074449.htm
Exercise induces the incorporation of nuclei in muscle fibers that may help the fibers regain size upon retraining after a period of atrophy brought on by muscle disuse, according to a study. Exercise enthusiasts know all too well that strength training of muscles leads to an increase in muscle size that is lost when the training is discontinued; the muscle fibers atrophy because of inactivity. But the mechanism by which previous episodes of training help atrophied fibers regain size relatively soon after retraining has long remained a mystery.

Thanks to a single-molecule imaging technique, researchers have revealed the mechanisms of PcrA helicase, an important DNA-regulating enzyme. To prevent unwanted recombination of a damaged or degraded section of DNA, the enzyme binds at the point of the break, where the double- and single-stranded regions meet. Then, it uses its motor function to "reel in" the tail, like a fisherman pulling in a rope, knocking off recombination proteins along the way.

An international study of more than 60,000 women has drawn new light on the relationship between osteoporosis and fractures. Scientists call for more to be done to identify and treat patients at the highest risk of fractures. Osteoporosis is more common in women who have fractured bones when they were younger - and they experience a similar loss in health-related quality of life as those with arthritis, lung disease, diabetes and other chronic diseases.

Ultimately, Charles Darwin's "endless forms most beautiful and most wonderful" can be boiled down to a scant 20 or so amino acids, the basic building blocks of life. From this parsimonious palette, nature paints the proteins that make up the wild diversity of life on earth, from the simplest bacteria to the most complicated structure in the known universe -- the human brain. Now, research reveals a new technique for tagging proteins with non-natural amino acids to scrutinize details about how they function.

At Point Reyes National Seashore in Marin County, Calif., a fierce battle is taking place between an invasive plant and a native plant, but one with a new twist. European beachgrass provides cover that allows a timid deer mouse to get close enough to the lupine to snip off stalks of lupine fruits without being nabbed by overflying birds. The two plants aren't in direct competition, but the beachgrass in this indirect way threatens the lupine's ability to survive.

Red blood cells have a tiny but effective protector -- microRNA
http://feeds.sciencedaily.com/~r/sciencedaily/~3/yMBI4DymGD4/100731210234.htm
Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused by chemicals called free radicals. The microRNA seems to have only a modest role when red blood cells experience normal conditions, but steps into action when the cells are threatened by oxidant stress. The study illustrates how microRNA fine-tunes gene activity.

Proteins linked with Alzheimer's, other neurodegenerative diseases found to clump in normal aging
http://feeds.sciencedaily.com/~r/sciencedaily/~3/O5giwaTfPDQ/100810203551.htm
In neurodegenerative diseases, clumps of insoluble proteins appear in patients' brains. These aggregates contain proteins that are unique to each disease, such as amyloid beta in Alzheimer's disease, but they are intertwined with small amounts of many other insoluble proteins that are normally present in a soluble form in healthy young individuals. For years, these other proteins were thought to be accidental inclusions in the aggregates, much as a sea turtle might be caught in a net of fish. Now, in a surprising new finding, researchers report that many of the proteins present as minor components of disease aggregates actually clump together as a normal part of aging in healthy individuals.

Breakthrough in blinking molecules phenomenon

A new paper offers an important new understanding of an enduring mystery in chemical physics. More than a century ago, at the dawn of modern quantum mechanics, the Noble Prize-winning physicist Neils Bohr predicted so-called "quantum jumps." He predicted that these jumps would be due to electrons making transitions between discrete energy levels of individual atoms and molecules. Although controversial in Bohr's time, such quantum jumps were experimentally observed, and his prediction verified, in the 1980s. More recently, with the development of single molecule imaging techniques in the early 1990s, it has been possible to observe similar jumps in individual molecules.

New insights into how antibodies are made suggests new approach for anti-cancer drug targets
http://feeds.sciencedaily.com/~r/sciencedaily/~3/fxuhH12N-3I/100810082644.htm
While investigating how white blood cells known as B cells develop, researchers have discovered that genes from the Phosphatidylinositol 3-kinase (PI3Ks) family of enzymes are critical in enabling the B cells to produce antibodies in the spleen and lymph nodes. PI3Ks are involved in a diverse range of activities inside cells, generating signalling molecules to control cell growth, proliferation, motility, survival and intracellular trafficking. Faults in these processes can lead to the development of cancer; consequently the PI3Ks are currently among the most hotly pursued drug targets in the pharmaceutical industry.
