According to a study conducted at Washington University School of Medicine in St. Louis, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts. Costs of climate change, state-by-state: Billions, says UMD Climate change will carry a price tag of billions of dollars for a number of U.S. states, says a new series of reports from the University of Maryland's Center for Integrative Environmental Research (CIER). The researchers conclude that the costs have already begun to accrue and are likely to endure.

A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts. New study finds advanced liver cancer patients live longer by taking anti-cancer drug sorafenib Researchers at Mount Sinai School of Medicine in New York have found that sorafenib (Nexavar) helps patients with advanced liver cancer live about 44 percent longer compared with patients who did not receive the anti-cancer drug. Cow power could generate electricity for millions Converting livestock manure into a domestic renewable fuel source could generate enough electricity to meet up to three per cent of North America's entire consumption needs and lead to a significant reduction in greenhouse gas emissions (GHGs), according to US research published today. Why eating less can help the environment An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. Study shows parasites outweigh predators In a study of free-living and parasitic species in three estuaries on the Pacific coast of California and Baja California, a team of researchers from the University of California, Santa Barbara, the United States Geological Survey, and Princeton University has determined that parasite biomass in those habitats exceeds that of top predators, in some cases by a factor of 20. Cool! Nanoparticle research points to energy savings Adding just the right dash of nanoparticles to standard mixes of lubricants and refrigerants could yield the equivalent of an energy-saving chill pill for factories, hospitals, ships, and others with large cooling systems, suggest the latest results from National Institute of Standards and Technology (NIST) research that is pursuing promising formulations. Biofilms use chemical weapons Bacteria rarely come as loners; more often they grow in crowds and squat on surfaces where they form a community together. Polarizing filter allows astronomers to see disks surrounding black holes For the first time, a team of international researchers has found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be. You're more likely to do sport if you are white, middle class, and middle-aged The comfortably off, white, and middle aged are the most likely to participate in sporting activities, reveals a 10 year study published ahead of print in the British Journal of Sports Medicine. Parasites Outweigh Predators in Pacific Coast Estuaries In a study of parasites living in three estuaries on the Pacific coast of California and Baja California, researchers have determined that biomass of these parasites exceeds that of top predators, in some cases by more than 20 times. NIST membrane model may unlock secrets of early-stage Alzheimer's Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a neuron's structure and function. 1 missing gene leads to fruitless mating rituals Male fruit flies missing a gene for one particular odor receptor become clueless in matters of love, scientists at Duke University Medical Center have discovered. Autism's social struggles due to disrupted communication networks in brain Picking up on innuendo and social cues is a central component of engaging in conversation, but people with autism often struggle to determine another person's intentions in a social interaction. Limiting fructose may boost weight loss, UT Southwestern researcher reports One of the reasons people on low-carbohydrate diets may lose weight is that they reduce their intake of fructose, a type of sugar that can be made into body fat quickly, according to a researcher at UT Southwestern Medical Center. 'Statins' linked to improved survival in kidney transplant recipients For patients receiving kidney transplants, treatment with cholesterol-lowering "statin" drugs may lead to longer survival, reports a study in the November 2008 Journal of the American Society of Nephrology (JASN). Soy foods are associated with lower sperm concentrations Men who eat an average of half a serving of soy food a day have lower concentrations of sperm than men who do not eat soy foods, according to research published online in Europe's leading reproductive medicine journal, Human Reproduction, today (Thursday 24 July). The association was particularly marked in men who were overweight or obese, the study found. Licking your wounds: Scientists isolate compound in human saliva that speeds wound healing A report by scientists from The Netherlands published online in The FASEB Journal (http://www.fasebj.org) identifies a compound in human saliva that greatly speeds wound healing. Sex and lifespan linked in worms: a family of sugar-like molecules controls both A group of scientists who set out to study sex pheromones in a tiny worm found that the same family of pheromones also controls a stage in the worms' life cycle, the long-lived dauer larva. Slippery customer: A greener antiwear additive for engine oils Titanium, a protean element with applications from pigments to aerospace alloys, could get a new role as an environmentally friendly additive for automotive oil, thanks to work by materials scientists from Afton Chemical Corporation (Richmond, Va.) and the National Institute of Standards and Technology (NIST). No justification for denying obese patients knee replacements There is no justification for denying obese patients knee replacement surgery: They benefit almost as much as anyone else from the procedure, concludes a small study published ahead of print in the Annals of the Rheumatic Diseases. Study shows emergency physicians have good first instincts in diagnosing heart attacks A study out of Wake Forest University Baptist Medical Center demonstrates emergency room doctors are correctly identifying patients who are having a heart attack, even when laboratory tests haven't yet confirmed it. NIST trumps the clumps: Making biologic drugs safer Scientists at the National Institute of Standards and Technology (NIST) have developed a technique to measure the formation of clumps of proteins in protein-based pharmaceuticals. Making Patients Move Requires the Right Exercise Advice It is common knowledge that regular exercise supports physical and mental well-being. Despite this and recommendations from health care providers, the majority of patients with chronic illnesses remain inactive Patient privacy assured by electronic censor Newly developed software will help to allay patients' fears about who has access to their confidential data. Study suggests human visual system could make powerful computer Since the idea of using DNA to create faster, smaller, and more powerful computers originated in 1994, scientists have been scrambling to develop successful ways to use genetic code for computation. Effect of microstructure on the coercivity of HDDR Nd-Fe-B permanent magnetic alloy The School of Physics, Shandong University, has shown that the coercivity mechanism of HDDR Nd-Fe-B permanent magnetic alloy is greatly related to its microstructure defect at the grain boundary. The investigation can provide a clear understanding of coercivity mechanism, and hence will be reported in Science in China Series G-Physics, Mechanism and Astronomy. |
