Saturated fat may interfere with creating memories in aged brain

New research hints at a few ways fatty foods affect cells in the brain, a finding that could help explain the link between a high-fat diet and impaired memory -- especially as we age. A new study in cell cultures found the omega-3 fatty acid DHA may help protect the brain from an unhealthy diet's effects by curbing fat-induced inflammation at the cellular source.

Down goes antimatter! Gravity's effect on matter's elusive twin is revealed

For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.

Increasing steps by 3,000 per day can lower blood pressure in older adults, study finds

An estimated 80 percent of older adults in the U.S. have high blood pressure. Maintaining healthy blood pressure can protect against serious conditions like heart failure, heart attacks, and strokes. A new study found that adding a relatively minimal amount of movement, about 3,000 steps per day, can significantly reduce high blood pressure in older adults.

Efficient fuel-molecule sieving using graphene

A research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.
