Overactive cell metabolism linked to biological aging

Why do cells, and by extension humans, age? The answer may have a lot to do with mitochondria, the organelles that supply cells with energy. Though that idea is not new, direct evidence in human cells had been lacking. Until ...

Self-assembling molecules could help in cancer therapy

Treatment of cancer is a long-term process because remnants of living cancer cells often evolve into aggressive forms and become untreatable. Hence, treatment plans often involve multiple drug combinations and/or radiation ...

Bumblebees appear to feel pain

New research by a team at Queen Mary University of London shows that bumblebees can modify their response to 'noxious' (painful) stimuli in a manner that is viewed in other animals as consistent with the ability to feel pain.

Drought: Clear impacts on global agricultural production

Maize, rice, soybean, and wheat are key in the debate concerning food, land, water and energy security and sustainability. The human consumption vs. animal feed competition nourished the debate about the environmental footprints ...

Balancing protein in your diet could improve water quality

Balancing how much protein you eat with the amount your body needs could reduce nitrogen releases to aquatic systems in the U.S. by 12% and overall nitrogen losses to air and water by 4%, according to a study from the University ...

European diets need to change to reduce climate impact

The amount of poultry in European diets isn't conducive to an optimal circular food system, which prioritizes crops that produce healthy foods while reducing or reusing waste streams, a new Cornell University research finds.

Pesticide threat to bees likely 'underestimated': study
