Stanford researchers create hydrogen fuel from seawater

Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. A Stanford-led team has now developed a way to harness seawater – Earth’s most abundant source – for chemical energy. |SOURCE| By Erin I. Garcia de Jesus | Stanford researchers have devised a way to generate hydrogen fuel [...] Read more

Scientists grow 'mini-brain on the move' that can contract muscle

Cambridge researchers grew ‘organoid’ that spontaneously connected to spinal cord. |SOURCE| Scientists have grown a miniature brain in a dish with a spinal cord and muscles attached, an advance that promises to accelerate the study of conditions such as motor neurone disease. The lentil-sized grey blob of human brain cells were seen to [...] Read more

Physicists Create Coldest Quantum Gas of Molecules

Physicists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, have produced a gas of potassium-rubidium molecules at temperatures as low as 50 nanokelvin (nK) — that’s 50 billionths of a Kelvin, or just a smidge above absolute zero. The two atoms involved are in different [...] Read more

De novo origins of multicellularity in response to predation

The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve. Predation is hypothesized as one selective pressure that may have driven the evolution of multicellularity. Here we show that de novo origins of simple [...] Read more
