Embryo stem cells created from skin cells

Researchers have found a way to transform skin cells into the three major stem cell types that comprise early-stage embryos. The work (in mouse cells) has significant implications for modeling embryonic disease and placental dysfunctions, as well as paving the way to create whole embryos from skin cells.

These trippy images were designed by AI to super-stimulate monkey neurons

To find out which sights specific neurons in monkeys 'like' best, researchers designed an algorithm, called XDREAM, that generated images that made neurons fire more than any natural images the researchers tested. As the images evolved, they started to look like distorted versions of real-world stimuli.

An evolutionary rescue in polluted waters

The combination of a big population, good genes and luck helps explain how a species of fish in the Houston Ship Channel was able to adapt to what normally would be lethal levels of toxins for most other species. The exceptional survivor story of the Gulf killifish can provide insights into what other species may need to adapt to drastically changed environments.

Organ bioprinting gets a breath of fresh air

Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs. It's a breakthrough technique for bioprinting tissues with exquisitely entangled vascular networks that mimic the body's natural passageways for blood, air, lymph and other vital fluids.

Running may have made dinosaurs' wings flap before they evolved to fly

Before they evolved the ability to fly, two-legged dinosaurs may have begun to flap their wings as a passive effect of running along the ground.

Pinpointing Gaia to map the Milky Way

This image, a composite of several observations captured by ESO's VLT Survey Telescope (VST), shows the ESA spacecraft Gaia as a faint trail of dots across the lower half of the star-filled field of view. These observations were taken as part of an ongoing collaborative effort to measure Gaia's orbit and improve the accuracy of its unprecedented star map.

Bats evolved diverse skull shapes due to echolocation, diet

Scientists have discovered that two major forces have shaped bat skulls over their evolutionary history: echolocation and diet. Their findings help explain the wide diversity of skull shapes among bats and reveal the intricate details of how evolutionary pressures can shape animal bodies.

River wildlife contain cocaine, pharmaceuticals and pesticides

For the first time, researchers have found a diverse array of chemicals, including illicit drugs and pesticides in UK river wildlife. The study looked at the exposure of wildlife, such as the freshwater shrimp Gammarus pulex, to different micropollutants (chemicals found at exceptionally low levels) and the levels of these compounds in the animals.
