Studies in Royal Society journals include stress in birds and depletion of medieval fish stocks
... Rat whiskers form a powerful sensory system that works where eyes do not, for instance in dark or smoky environments; the benefits to robotics of reproducing this system are clear. Previously, it has not been understood how the whisker and follicle transform stimuli into nerve impulses, so we have built ...Heart protein could be used to repair damage caused by heart attack
...estern researchers discovered that Thymosin beta-4 works in conjunction with two other proteins to promote survival and migration of heart muscle cells by activating the protein Akt/Protein Kinase B. Akt/PKB, when active, promotes cell survival. After studying the activity of cells in culture, resea...Forensic clock calls time on crime
...l, DOI: 10.1016/j.forsciint.2004.04.071). The test works with just one microlitre of blood and might even be sensitive enough to tell investigators when a fingerprint was left, though the team have not yet tried this. Bishop is not sure why rRNA breaks down more slowly, but he believes it may be because ...New method to measure ancient land elevation developed by Field Museum scientist
...sue. "This is the first paleobotanical method that works globally and is independent of long-term climate change. "The new method will help us to understand the rate at which some of the Earth's most important mountains have uplifted," she added. "It will also show how the process of mountain building infl...Researchers reconstruct parts of the genome of a common mammalian ancestor
...acy. The technique works particularly well for placental mammals, because the rapid radiation of lineages after the time of the common ancestor produced many different versions of the original sequence that can be compared. For common ancestors with fewer living descendant s...Fussy Baby Network answers cries for help in community

... of Molecular Cell . Understanding how DNA repair works is critical to understanding the development of cancer, which often occurs when DNA is not properly repaired. In addition, notes Michael Lieber, M.D., Ph.D., the Rita and Edward Polusky Chair in Basic Cancer Research at the Keck School who heads up t...Scientists discover key egg enzyme for blocking sperm entry after fertilization
...n. The enzyme, named urchin dual oxidase 1 (Udx1), works with other cellular components to produce peroxide and keep it away from the fragile embryo. "Peroxide is what we put on skinned knees to kill germs and on hair to get that summer sun-streaked appearance. It is not something we would expect an egg to...Impulsive behavior may be relict of hunter-gatherer past
...r in the future,'" Stephens said. "Being impulsive works really well because after grabbing the food, they can forget it and go back to their original foraging behavior. That behavior can achieve high long-term gains even if it's impulsive." The work may apply to humans, he said, because taking rewar...Scientists solve the mystery of how Botox attacks nerves and eliminates wrinkles
...A-approved imitation of Botox. The botulinum toxin works by invading nerve cells, where it releases an enzyme that prevents muscle contraction. In recent years, scientists have determined that the enzyme binds to specific sites on proteins called SNAREs, which form a complex in the synapse between nerve an...Strange ocean wave patterns raise questions about beach erosion
... Researchers need to better understand how erosion works in order to develop better mitigation strategies, Lippmann said. That's why researchers from many different institutions have planted special underwater sensors along the beach in Duck, NC. Although the sensors take very accurate measurements of wate...MIT team aims to mend broken hearts
