Diabetes Drug Shows Promise In Fighting Lethal Cancer Complication
Insulin resistance, the hallmark of type 2 diabetes and a condition often associated with obesity, is paradoxically also an apparent contributor to muscle wasting and severe fat loss that accompanies some cancers, according to new research. Frequent Hemodialysis At Night May Improve Some Outcomes For Patients
Patients who received hemodialysis at night six times a week for treatment of end-stage kidney disease had improvements on certain outcomes, including reduced need for blood pressure medications and improvement in selected quality of life measures, compared to patients who received conventional hemodialysis three times weekly, according to a new article. IPod Shuffle Knockoff Rides Again
Taiwan gadget maker Luxpro is back in business and is countersuing Apple for $100 million in lost revenue. In Gear Factor. Smell-wars Between Butterflies And Ants
Large blue butterflies manage to have their larvae adopted and cared-for by ant colonies. They deceive the ants into feeding them while letting their own brood starve. The caterpillar deception is a matter of smell, and there is an ongoing co-evolutionary arms race in smell similarity between cheaters and their victims. Researchers identify scaffold regulating protein disposal
How does a cell manage to identify and degrade the diverse types of defective proteins and thus protect the body against serious diseases? Researchers have found a crucial piece in this puzzle. In an enzyme complex that plays a critical role in the quality control of proteins, they discovered a scaffold regulating the identification and disposal of various defectively produced proteins. Discovery May Provide New Treatments For Alcohol Dependence
Researchers have discovered a new brain mechanism involved in alcohol addiction involving the stomach hormone ghrelin. When ghrelin's actions in the brain are blocked, alcohol's effects on the reward system are reduced. It is an important discovery that could lead to new therapies for addictions such as alcohol dependence. How Stem Cells Decide To Become Either Skeletal Or Smooth Muscle
Researchers have discovered that a key protein controls how stem cells 'choose'to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels. The results suggest new ways to treat atherosclerosis and cancer, diseases that involve the creation of new blood vessels from stem cell reserves that would otherwise replace worn out skeletal muscle. Scientists use light to map neurons' effects on one another
Scientists have used light and genetic trickery to trace out neurons' ability to excite or inhibit one another, literally shedding new light on the question of how neurons interact with one another in live animals. Eat Less To Live Longer: Calorie Restriction Linked To Long Healthy Li
For nearly 70 years scientists have known that caloric restriction prolongs life. In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive. Researchers have now discovered two genes in mammalian cells that act as gatekeepers for cellular longevity. When cells experience certain kinds of stress, such as caloric restriction, these genes rev up and help protect cells from diseases of aging. Smog Schmog
In his climate-change ain’t happening State of the Union speech of Sept. 25th, Sen. James Inhofe (R-OK) makes the claim that climate change “skeptic” scientists do not get a fair share of media coverage. But, according to DeSmogBlog a quick infomart media search of US papers shows there have been more than 350 mentions of [...]
