Mice brains shrink during winter, impairing some learning and memory

...ike many mammals, mice need to reduce their energy costs during winter, and the brain is a good place to do that." And while there are obviously many differences between mice and humans, studies like this may one day help researchers gain insight into seasonal brain dysfunctions in humans such as seasonal...

Fungus Effective Against Winged Termites

...dreds of millions of dollars in damage and control costs each year. Emerging in late April through June, the winged adults fly briefly before they drop to the ground, shed their wings and find a mate with which to start a new colony that may grow to hundreds of thousands of wood-destroying termites. The r...

At the molecular level, the predator is the prey

...is to understand if there is a balance between the costs of the changes in the channel pore structure on channel function and the benefits of changes in TTX binding." The evolution of new traits often happens one of two ways, either by altering existing genes or by changing patterns and amounts of express...

Single-donor Islet Transplantation Procedure Shows Promise For Patients With Type 1 Diabetes

Hering, M.D., of the University of Minnesota, Minneapolis, and colleagues conducted a study to assess the effectiveness and safety of islet transplantation from a single pancreas. T...

UCLA study assesses cost-effectiveness of Hepatitis B drugs

...osis and other factors affecting treatment. Health costs included physician visits, diagnostic tests and complications of chronic liver disease. Investigators based the model on average 40-year old patients with the most common type of chronic hepatitis B -- with elevated liver enzymes but no liver cirrho...

Anammox bacteria produce nitrogen gas in oceans' snackbar

...ent nitrogen removal from waste water. The running costs of a waste water treatment system using the anammox process are only 10% of the costs of current treatment systems using conventional methods. Additionaly, the anammox process could redu...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...d in assisted reproduction, it is more complex and costs more than traditional methods. Using mouse oocytes, 80 percent of eggs that had been vitrified became fertilized with ICSI, with a live birth rate of about 30 percent, comparable to conventional IVF when eggs are not frozen. The fertilization and bi...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

The new approach is described in a paper, "Electrochemically Assisted Microbial Production of Hydrogen from Acetate," r...

Light therapy may combat fungal infections, new evidence suggests

...is vital to increase the benefits and decrease the costs that fungi present." The researchers first tested the importance of genes with known roles in light sensitivity of another, distantly related fungus. Yeast strains lacking one of those genes, known as white collar 1 (BWC1), mated equally well in the...

Researchers devise way to mass-produce embryonic stem cells

... cells like this could reduce stem cell production costs by at least 80 percent, Yang said, as it requires less equipment and monitoring. Embryonic stem cells are unspecialized, or undifferentiated, cells that can grow into any of the body's 200 different types of cells. Yang and Ouyang presented their f...
