Given the sharp rise in new cases of diabetes, this finding means that more adults may soon be living with mild but lasting deficits in their thought processes.... Gold Nanoparticles For Controlled Drug Delivery - Using tiny gold particles and infrared light, MIT researchers have developed a drug-delivery system that allows multiple drugs to be released in a controlled fashion.... Gene Expression And Splicing Vary Widely From One Tissue To The Next - Genes talk to themselves and to each other to control how a given cell manufactures proteins. But variation in the control of the same gene in two different tissues may contribute to certain human traits, including the likelihood of getting a disease, said a team of geneticists and neuroscientists.... Grazing Animals Help Spread Plant Disease - Researchers have discovered that grazing animals such as deer and rabbits are actually helping to spread plant disease -- quadrupling its prevalence in some cases -- and encouraging an invasion of annual grasses that threaten more than 20 million acres of native grasslands in California.... Teens Girls Smoke Now, Pay Later With Larger Waistlines As Adults - Remember the cool girls, huddled together in high school restrooms, puffing their cigarettes? Well, here's consolation for the nerds in the crowd: Those teen smokers are more likely to experience obesity as adults, according to a new study from Finland.... Stars Forming Just Beyond Black Hole's Grasp At Galactic Center - The center of the Milky Way presents astronomers with a paradox: It holds young stars, but no one is sure how those stars got there. The galactic center is wracked with powerful gravitational tides stirred by a 4 million solar-mass black hole. Those tides should rip apart molecular clouds that act as stellar nurseries, preventing stars from forming in place. Yet the alternative -- stars falling inward after forming elsewhere -- should be a rare occurrence.... Obesity Linked To Elevated Risk Of Ovarian Cancer - A new epidemiological study has found that among women who have never used menopausal hormone therapy, obese women are at an increased risk of developing ovarian cancer compared with women of normal weight.... Amazon Deforestation Trend On The Increase - Deforestation in Brazil's Amazon forests has flipped from a decreasing to an increasing trend, according to new annual figures recently released by the country's space agency INPE....

Possible Abnormality In Fundamental Building Block Of Einstein's Theory Of Relativity - Physicists have developed a promising new way to identify a possible abnormality in a fundamental building block of Einstein's theory of relativity known as "Lorentz invariance." If confirmed, the abnormality would disprove the basic tenet that the laws of physics remain the same for any two objects traveling at a constant speed or rotated relative to one another.... Defensive Protein Killed Ancient Primate Retroviruses, Research Suggests - Retroviruses are the worst sort of guest. Over eons, these molecular parasites have insinuated themselves into their hosts' DNA and caused a ruckus. The poor hosts can't even be rid of the intruders by killing them, because they stubbornly remain after death.... New Park Protects Penguins And Other Marine Life In Argentina - A new coastal marine park has recently been signed into law by the Government of Argentina. The park protects half a million penguins along with several species of rare seabirds and the region's only population of South American fur seals. It is the first protected area in Argentina specifically designed to safeguard not only onshore breeding colonies but also areas of ocean where wildlife feed at sea.... Alternative Way To Save Brain Cells After Stroke Or Head Trauma, New Finding Suggests - Shredded extracellular matrix is toxic to neurons. Researchers reveal a new mechanism for how ECM demolition causes brain damage. The study suggests that drugs that block KA1, one subunit of the kainate receptor, might provide an alternative way to save brain cells after stroke or head trauma.... Genetic Modification Turns E. Coli Bacteria Into High Density Biofuel - Scientists have successfully pushed nature beyond its limits by genetically modifying Escherichia coli, a bacterium often associated with food poisoning, to produce unusually long-chain alcohols essential in the creation of biofuels.... Early Family Depression Has Lasting Effects On Teens, Young Adults - A new study on 485 Iowa adolescents over a 10-year period (1991-2001) found that early socioeconomic adversity experienced by children contributes to poor mental health by the time they become teens -- disrupting their successful transition into adulthood....

Two financial researchers at BI Norwegian School of Management have identified a target indicator that can predict future return on shares.... Power Of Wilderness Experiences As A Catalyst For Change In Young Offenders - Researchers have been working with young offenders to help them turn their lives around. Findings of the self-reported measures of self-confidence, trust, belonging and connectedness to nature showed that after each wilderness experience, feelings increased and during the months in between levels fell, as participants had less contact with nature. The final value at the end of the project was substantially higher than the initial starting value.... Four, Three, Two, One . . . Pterosaurs Have Lift Off - Pterosaurs have long suffered an identity crisis. Pop culture heedlessly -- and wrongly -- lumps these extinct flying lizards in with dinosaurs. Even paleontologists assumed that because the creatures flew, they were birdlike in many ways, such as using only two legs to take flight.... Physicists Squeeze Light To Quantum Limit - Physicists have demonstrated a way to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next generation atomic clocks, novel quantum computing and our most fundamental understanding of the universe....

Protein That Protects Against Alzheimer's? - Research on the mechanisms involved in neurodegenerative diseases such as Alzheimer's, stroke, dementia, Parkinson's and multiple sclerosis, to name a few, has taken a step forward thanks to the work of researchers who have successfully demonstrated the protective and reparative role of apolipoprotein D, or ApoD, in neurodegenerative diseases. Their discovery suggests interesting avenues for preventing and slowing the progression of this type of illness.... Genetic Mutation Causes Familial Susceptibility For Degenerative Brain Disease - Mutation of a gene that helps proteins migrate in and out of the cell's genetic command center -- the nucleus -- puts some families at higher risk for the degenerative brain disease acute necrotizing encephalopathy.... Obesity: Reviving The Promise Of Leptin - The 1995 discovery of leptin, an appetite-suppressing hormone, generated great hopes for an effective obesity drug. But hopes dimmed when it was found that obese people are leptin-resistant. Now, researchers have, for the first time, re-sensitized the brain to leptin, using oral drugs that are already FDA-approved. In mice, this led to significant weight loss when combined with leptin treatment.... Protein Has Pivotal Role In Obesity, Metabolic Syndrome - COUP-TFII, a protein known to play a role in development and the formation of organs is also an important factor in the control of obesity and diabetes, said researchers in the journal Cell Metabolism.... On A High-fat Diet, Protective Gene Variant Becomes Bad Actor - New evidence in mice bolsters the notion that a version of a gene earlier shown to protect lean people against weight gain and insulin resistance can have the opposite effect in those who eat a high-fat diet and are heavier, reveals a new report in the journal Cell Metabolism....
