For the first time, engineers and scientists at Caltech have been able to directly observe the ultrafast motion of electrons immediately after they are excited with a laser—and found that these electrons diffuse into their surroundings much faster and farther

Scientists dream of using custom organisms to fight illnesses or even build computers, but there’s a problem: it’s difficult to make the sweeping genetic changes that would give you exactly the lifeform you need. To that end, researchers have found

A 7-year-old with congenital heart disease became the first person to visit Saturn, thanks to the Make-A-Wish Foundation and a little virtual reality magic. Zayden Wright, 7, of Georgia said his biggest dream was to visit outer space. “He’s fascinated

Malaria parasites cause red blood cells to become bendier, helping the parasites to enter and cause infection, says a new study. Malaria is caused by a family of parasites that are carried by mosquitoes. Once parasites enter the body through

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved. New research demonstrates the real-world potential of providing clean drinking water

The complex trade is increasing pressure on non-renewable groundwater, mainly used for irrigating crops such as rice, wheat and cotton. Pakistan, the US and India are the countries exporting the most food grown with unsustainable water. Researchers say that without
