New study finally explains why calorie restriction can extend your lifespan

It might actually have more to do with sleep than what you eat.

Epidural stimulation shown to normalize blood pressure following spinal cord injury

Working with human research participants, researchers have found that spinal cord epidural stimulation can safely and effectively elevate blood pressure in individuals with SCI along with chronic hypotension.

Obesity surgery linked to positive outcomes in very obese teens with diabetes

This study is the first to compare glycemic control in two groups of very obese adolescents with type 2 diabetes.

For graphite pellets, just add elbow grease

Researchers crush and press functionalized graphene to make strong, light graphite pellets that hold promise for electronic and catalytic applications.

Using light to turn yeast into biochemical factories

Researchers have used a combination of light and genetic engineering to controlling the metabolism, or basic chemical process, of a living cell. Building on techniques that already have transformed the field of neuroscience, the researchers used light to control genetically-modified yeast and increase its output of commercially valuable chemicals.

Direct evidence of exposure of pregnant women to herbicide ingredient

The first birth cohort study of its kind has found more than 90 percent of a group of pregnant women in Central Indiana had detectable levels of glyphosate, the active ingredient in Roundup, the most heavily used herbicide worldwide.

Waterbirds affected by low water, high salt levels in lakes

A recent study shows food sources for migratory birds decline with low water levels and high salt content in lakes.

Measurement chip detects Legionella

In an outbreak of Legionnaires' disease, finding the exact source as quickly as possible is essential to preventing further infections. To date, a standard analysis takes days. Researchers have now developed a rapid test that achieves the same result in about 35 minutes.

Bacteria eat greenhouse gas with a side of protein

With the ability to leech heavy metals from the environment and digest a potent greenhouse gas, methanotrophic bacteria pull double duty when it comes to cleaning up the environment. But before researchers can explore potential conservation applications, they first must better understand the bacteria's basic physiological processes. New research has identified two never-before-studied proteins, called MbnB and MbnC, as partially responsible for the bacteria's inner workings.

Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought

The existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk. New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought. « Previous PageNext Page »
