Chronic Voluntary Alcohol Consumption Impairs NeurogenesisA new study found that chronic alcohol consumption reduces the number of new brain cells that form in the hippocampus of adolescent rhesus monkeys. This finding suggests these cells are vulnerable to alcohol and their presence may be essential for preventing alcohol dependence.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 3:00 pm Smallest Nanoantennas For High-speed Data NetworksMore than 120 years after the discovery of the electromagnetic character of radiowaves by Heinrich Hertz, wireless data transmission dominates information technology. Higher and higher radio frequencies are applied to transmit more data. Some years ago, scientists found that light waves might also be used for radio transmission. So far, manufacture of the small antennas has required an enormous expenditure. Scientists have now succeeded in specifically and reproducibly manufacturing smallest optical nanoantennas from gold.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 3:00 pm Could Drugs For Mood Disorders, Pain And Epilepsy Cause Psychiatric Disorders Later In Life?Young animals treated with commonly-prescribed drugs develop behavioral abnormalities in adulthood say researchers. The drugs tested include those used to treat epilepsy, mood disorders and pain.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 3:00 pm Arctic Sediments Show That 20th Century Warming Is Unlike Natural VariationThe possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to new evidence. The research reveals that sediments retrieved by geologists from a remote Arctic lake are unlike those seen during previous warming episodes.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 3:00 pm DNA Replication: Messenger RNA With FLASH A Key PlayerA new study has identified a key player in a molecular process essential for DNA replication within cells.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 3:00 pm New Route To Nano Self-assembly FoundBy adding select small molecules to mixtures of nanoparticles and polymers, researchers can direct the self-assembly of the nanoparticles into arrays of one, two and even three dimensions with no chemical modifications.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 3:00 pm Trembling Hands And Molecular HandshakesThe heritable Fragile X tremor/ataxia syndrome is a common neurodegenerative disease. It is assumed to result from a relative lack of the protein Pur-alpha. A new study by a team in Germany provides important insights into the structure and function of this protein, which may lead to the development of a therapy.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 9:00 am Color Differences Within And Between Species Have Common Genetic OriginSpend a little time people-watching at the beach and you're bound to notice differences in the amount, thickness and color of people's body hair. Then head to the zoo and compare people to chimps, our closest living relatives. The body hair difference is even more pronounced between the two species than within our own species. Do the same genes cause both types of variation? New research shows that, at least for body color in fruit flies, the two kinds of variation have a common genetic basis.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 9:00 am Could Some Forms Of Mental Retardation Be Treated With Drugs?Growth factors are the proteins that trigger a countless number of actions in cells. Drugs that increase or decrease certain growth factors have lead to treatments for cancer and cardiovascular diseases. Researchers say a new understanding of a growth factor implicated in some mental retardation disorders could lead to a novel treatment.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 9:00 am Physicists Turn To Radio Dial For Finer Atomic MatchmakingInvestigating mysterious data in ultracold gases of rubidium atoms, scientists have found that properly tuned radio-frequency waves can influence how much the atoms attract or repel one another, opening up new ways to control their interactions.Source: ScienceDaily: Latest Science News | 25 Oct 2009 | 9:00 am Leaders of 16 Asian nations meet in Thailand (AP)AP - Leaders of 16 Asian countries gave high priority Sunday to finding a new economic growth model to free half the world's population from merely serving as producers for the West, the Thai prime minister said.Source: Yahoo!
