Battery-free robots use origami to change shape in mid-air      (via sciencedaily.com) 

Researchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air.

Your body's own cannabinoid molecules calm you during stress      (via sciencedaily.com)     Original source 

When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.

Hot summer air turns into drinking water with new gel device      (via sciencedaily.com) 

Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.

Water world? Methane, carbon dioxide in atmosphere of massive exoplanet      (via sciencedaily.com) 

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb's discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

Researchers grow embryonic humanized kidneys inside pigs for 28 days      (via sciencedaily.com)     Original source 

Researchers have successfully created chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing humanized kidneys had normal structure and tubule formation after 28 days. This is the first time that scientists have been able to grow a solid humanized organ inside another species, though previous studies have used similar methods to generate human tissues such as blood or skeletal muscle in pigs.

Ravenous black hole consumes three Earths'-worth of star every time it passes      (via sciencedaily.com) 

Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.

'Monstrous births' and the making of race in the nineteenth-century United States      (via sciencedaily.com)     Original source 

From the Middle Ages to the Enlightenment, 'monstrous births' -- malformed or anomalous fetuses -- were, to Western medicine, an object of superstition. In 19th-century America, they became instead an object of the 'modern scientific study of monstrosity,' a field formalized by French scientist Isidore Geoffroy Saint-Hilaire. This clinical turn was positioned against the backdrop of social, political, and economic activity that codified laws governing slavery, citizenship, immigration, family, wealth, and access to resources.

Machine learning contributes to better quantum error correction      (via sciencedaily.com) 

Researchers have used machine learning to perform error correction for quantum computers -- a crucial step for making these devices practical -- using an autonomous correction system that despite being approximate, can efficiently determine how best to make the necessary corrections.
