A team of Harvard scientists have succeeding in measuring the magnetic charge of single particles of matter and antimatter more accurately, by capturing individual protons and antiprotons in a "trap" created by electric and magnetic fields and precisely measuring the oscillations of each particle.

The researchers were able to measure the magnetism of a proton more than 1,000 times more accurately than an antiproton had been measured before. Similar tests with antiprotons produced a 680-fold increase in accuracy in the size of the magnet in an antiproton.    

Fluctuating wind speed and direction means turbines generate power inconsistently. Coupled with customers' varying power demand, the results is that many wind-farm managers end up wasting power-generation capacity and limiting the service life of turbines through active control, including fully stopping turbines, in order to damage to the power grid from spikes in supply.

Over 200 million years ago, a mass extinction wiped out an estimated 76 percent of marine and terrestrial species. It marked the end of the Triassic period and the onset of the Jurassic, clearing the way for dinosaurs to dominate Earth for the next 135 million years. 

It's not clear what caused the end-Triassic extinction, although most scientists agree on a likely scenario; over a relatively short time period, massive volcanic eruptions from a large region known as the Central Atlantic Magmatic Province (CAMP) spewed forth huge amounts of lava and gas, including carbon dioxide, sulfur and methane. 

An innovative new process releases the energy in coal without burning, while capturing carbon dioxide, the major greenhouse gas that is the target of emissions reduction goals. How close is it to commercial use?  It has passed an important milestone - a successful 200-hour test on a sub-pilot scale version of the technology using two inexpensive but highly polluting forms of coal.   

Consumption of extra virgin olive oil has been linked to reduced risk of Alzheimer's disease (AD) and its benefit may lie in one component of olive oil that helps shuttle the abnormal AD proteins out of the brain.

A team of scientists has uncovered how some sea snakes have developed 'shrunken heads' - literally smaller physical features than their related species.

A large head would seem to be a welcome trait for sea snakes, which typically have to swallow large spiny fish. However, there are some circumstances where it wouldn't be very useful: sea snakes that feed by probing their front ends into narrow, sand eel burrows have evolved comically small heads.
