Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain
UW-Madison scientists have found a new way to sneak drugs past the blood-brain barrier by engineering and implanting progenitor brain cells derived from stem cells to produce and deliver a critical growth factor that has already shown clinical promise for treating Parkinson's disease. Worker Ants Store Fat To Share With Colony Members During Times Of Nee
In a fascinating new study, researchers explore the ability of ants to store excess fat and pass it to colony members through lipid-rich oral secretions or unfertilized eggs. For perennial organisms, such as ant colonies, investing heavily in nutrient stores when food availability is high is a potential bet-hedging strategy for dealing with times of famine. Captain Kidd's Shipwreck Of 1699 Discovered
Resting in less than 10 feet of Caribbean seawater, the wreckage of Quedagh Merchant, the ship abandoned by the scandalous 17th century pirate Captain William Kidd as he raced to New York in an ill-fated attempt to clear his name, has escaped discovery -- until now. An underwater archaeology team has just announced the discovery of the remnants. [Odd] A Romanian couple has named their son Yahoo as a sign of gratitu
Daily Libertatea said on Thursday Cornelia and Nonu Dragoman, both from Transylvania, met and decided they were meant for each other following a three-month relationship over the net.They married and had a baby this Christmas, whom they decided to name after one of the worldwide web's most popular portals."We named him Lucian Yahoo after my father and the net, the main beacon of my life,"Cornelia Dragoman was quoted as saying. Dispersal Or Drift? More To Plant Biodiversity Than Meets The Eye
Although we know how and when Pangaea broke apart, the distribution of fossils of the same species on many different continents, separated by vast ocean waters, challenges us to explain how they got there. Plant life on New Zealand, for example, shares striking similarities to that on other Southern Hemisphere land masses, but scientists have yet to agree on how this came to pass. Free-energy Theory Borne Out In Large-scale Protein Folding
Scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein. The interdisciplinary research appears this week in two back-to-back papers in the Proceedings of the National Academy of Sciences. The study involved pioneering efforts to establish comparable experimental and theoretical data, and Rice's team believes the method can be applied to other proteins. America's Test Kitchen

"All of the recipes from the television show plus variations that ended up on the cutting room floor."In "Equipment Corner"a tester gives advice on kitchen equipment purchases. Science Desk features a food science expert sharing "little-known facts about the foods we eat and enjoy every day."The Tasting Lab tests products such as all-purpose flour, hot dogs, red wines for cooking, and vanilla ice cream. Purdue Study Finds Races React Differently To Dietary Salt, Calcium
African-American and Caucasian adolescent girls handle sodium and calcium differently, which may help explain why the races have different rates of hypertension and osteoporosis, according to research at Purdue University. Nutrition researchers discovered Caucasian girls lose more calcium in their urine than African-American girls, but both races lose calcium at an accelerated rate when they consume a high-salt diet. Physical Inactivity Worsens GI Symptoms In Obese People
Physical activity may help reduce gastrointestinal (GI) symptoms in people who are obese. In a study published today in the American Gastroenterological Association (AGA) journal Clinical Gastroenterology and Hepatology, researchers found that a high body mass index (BMI) and lack of physical activity were associated with an increase in GI symptoms such as stomach pain, diarrhea, constipation and irritable bowel syndrome (IBS). Diet Linked To Cognitive Decline And Dementia
Research has shown convincing evidence that dietary patterns practiced during adulthood are important contributors to age-related cognitive decline and dementia risk.
