Bipolar Disorder More Prevalent And Costly Than Believed; Lithium Coul
Preliminary results of a new survey indicate 4.3 percent of U.S. adults suffer from a bipolar disorder, considerably higher than earlier studies estimating 1 percent prevalence. Its cost comes as a surprise as well, with a near $26 billion annual national price tag. Bipolar disorder accounts for nearly half of all suicidal deaths each year. How best to prevent these suicides? One study finds lithium, one of psychiatry's oldest drugs, the most effective solution. Twins Have Similar School Performance To Single-born Children
Twins have similar academic performance to single-born children, finds a large Danish study published online by the British Medical Journal. These findings challenge earlier research that show twins have considerably lower IQ in childhood than singletons. Breast Cancer May Be 'Uniquely Sensitive' To Inhibitors Of PI3K Pathwa
Because up to 75 percent of breast cancer patients have an abnormality in a specific cell signaling pathway, drugs that target different molecules along that pathway may be especially effective for treating the disease, says a researcher from The University of Texas M. D. Anderson Cancer Center. Check Your Judgments, Eh?
A conference about identity on the internet almost succeeds in squashing the sex-positive optimism that usually permeates Sex Drive. Commentary by Regina Lynn. Climate Pollution From Aviation Increasing
EU environment ministers have failed to seize a key opportunity to curbemissions from the aviation sector through the European Emissions Trading Scheme, WWF said at the conclusion of the EU Environment Council in Brussels. Scientists estimate that the effect of aviation emissions on the climate is up to five times the impact of emissions occurring on the ground. The Evolutionary Triumph Of Flower Power
While flowers originally came on the scene to attract potential pollinators like bugs and birds, it is their appeal to humans that accounts for the incredible variety of shapes and colors we see in domesticated flowers today. Rutgers researchers suggest that nature's prettier flowers got to survive and thrive because people didn't destroy them when they cleared land for agriculture. Instead, they cultivated them and have been doing so for more than 5,000 years. Right Blend Of Microbes And Plants Can Clean Up Toxic Spills
Superfund sites are infamous for their hazardous, stubborn chemical wastes, but one cleanup solution may be to put the right mix of plants and microbes together in the soil, according to a new University of Florida study. Testing Drugs on India's Poor
Pharmaceutical companies rush to try experimental medications on India's never-ending supply of poverty-stricken test subjects. Welcome to the real world of The Constant Gardener. By Scott Carney. MicroRNA Works With Ago2 Protein To Regulate Blood Cell Development
MicroRNAs became the stars of the RNA universe, when scientists found that these short RNAs can control whether or not genes are expressed. Provocative new findings cast new light on the genesis of these key biological regulators and how they carry out their function. Mechanism For Epstein-Barr Virus Protein's Role In Blood Cancers Disco
Earlier this year, researchers at the University of Pennsylvania School of Medicine identified a link between a critical cancer pathway and an Epstein-Barr Virus (EBV) protein. Their findings demonstrated a new mechanism by which EBV can transform human B cells from the immune system into cancerous cells. Now, they have found that the viral protein--called EBNA3C (for EBV nuclear antigen)--mediates the degradation of the retinoblastoma protein, an important molecular brake for cell proliferation.
