Helpful B cells lend a hand to developing neurons

http://ift.tt/eA8V8J Neuron myelination is critical to early mental development, and defects in myelination have been linked to neurodevelopmental disorders. Researchers found that B immune cells reside in the brains of developing mice, and play a key role in the myelination of neurons by oligodendrocytes. The findings suggest a new avenue of exploration for understanding the origin of disorders such as autism and schizophrenia.

How much snow accumulates in North America each year? More than scientists thought

http://ift.tt/eA8V8J Scientists have revised an estimate of snow volume for the entire continent, and they've discovered that snow accumulation in a typical year is 50 percent higher than previously thought. Researchersplace the yearly estimate at about 1,200 cubic miles of snow. If spread evenly across the surface of the continent from Canada to Mexico, the snow would measure a little over 7.5 inches deep.

Biophysicists discover how small populations of bacteria survive treatment

http://ift.tt/eA8V8J Small populations of pathogenic bacteria may be harder to kill off than larger populations because they respond differently to antibiotics.

Warm summers could weaken ocean circulation

http://ift.tt/eA8V8J Deep convection in the North Atlantic is one of the key components of the large-scale ocean circulation. Based on long-term observations, scientists have now demonstrated the influence of increased surface freshening in summer on convection in the following winter. Enhanced surface freshening and warmer winters have shortened the duration of ocean convection in the last decade.

Spectroscopic thermometer for nanomaterials

http://ift.tt/eA8V8J A scientific team has found a new way to take the local temperature of a material from an area about a billionth of a meter wide, or approximately 100,000 times thinner than a human hair. This discovery promises to improve the understanding of useful yet unusual physical and chemical behaviors that arise in materials and structures at the nanoscale.

Scientists describe potential antibody treatment for multidrug-resistant K. pneumoniae

http://ift.tt/eA8V8J Researchers are developing a promising alternative to antibiotic treatment for infections caused by Klebsiella pneumoniae bacteria resistant to carbapenem antibiotics. The approach uses antibodies to target the K. pneumoniae protective capsule polysaccharide, allowing immune system cells called neutrophils to attack and kill the bacteria.
