Tethered bilayer membrane 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.

New safety measures for soil fumigant pesticides

New safety measures for soil fumigant pesticides will increase protections for agricultural workers and bystanders - people who live, work, or otherwise spend time near fields that are fumigated. For the soil fumigants methyl bromide, chloropicrin, dazomet, metam sodium, and metam potassium, EPA will require a suite of new mitigation measures that will work together to protect human health.

Increased potassium/sodium in diet may decrease risk of hypertension, coronary heart disease and stroke

A new article indicates that an increased intake in minerals such as potassium, and possibly magnesium and calcium by dietary means may reduce the risk of high blood pressure and decrease blood pressure in people with hypertension. A high intake of these minerals in the diet may also reduce the risk of coronary heart disease and stroke.

Gene mutations in mice mimic human-like sleep disorder

Mutations in two genes that control electrical excitability in a portion of the brain involved in sleep create a human-like insomnia disorder in mice, UT Southwestern Medical Center researchers have found. The findings may help scientists better understand the disorder and provide an animal model for developing treatments.
