Near the center of the Milky Way lies this star-studded globular cluster, called Terzan 9 in the constellation Sagittarius.
Read MoreNew gel protects eggs—and maybe someday, heads—from damage
Humpty Dumpty, the famous egg of nursery rhyme fame, fell off a wall and couldn’t be put back together again. But if he’d worn a protective jacket made of gelatin and cornstarch, he could have stayed intact. Researchers in ACS Applied Materials & Interfaces report that by adding starch to gelatin, they have created gels […]
Read MoreResearchers discover a new receptor regulating sebaceous gland progenitor cell function
Stem cells and progenitor cells play an important role in the renewal of multiple tissues. Professor Jyrki Heino’s research group from the University of Turku together and Professor Fiona Watt´s research group from King’s College London have discovered a molecule called embigin on the surface of epithelia progenitor cells and proven its significance to sebaceous […]
Read More2D interfaces in future transistors may not be as flat as previously thought
Transistors are the building blocks of modern electronics, used in everything from televisions to laptops. As transistors have gotten smaller and more compact, so have electronics, which is why your cell phone is a super powerful computer that fits in the palm of your hand.
Read MoreUpcycling plastics through dynamic cross-linking
If bioengineers can upcycle commodity plastics into higher-performance materials, they can establish sustained closed-loop manufacturing with broader industrial and environmental benefits. For example, upcycled plastics can be reprocessed to form custom-designed structures via an energy-resource-efficient additive manufacturing circuit based on fused filament fabrication (the FFF method). In a new report now published in Science Advances, […]

I’ve written a number of times here about bifunctional protein degraders, which have been a big topic in drug discovery for the past few years. There’s a new paper that illustrates some of the challenges in this area, and it’s worth using as an example. For those outside the field, the idea behind these things […]
Read MoreRussia’s invasion could cause long-term harm to Ukraine’s prized soil
By now, wheat planted late last year waves in fields across Ukraine. Spring crops of sunflowers and barley are turning swaths of dark earth into a fuzz of bright green. But with Russia’s war being waged in some of the most fertile regions of Ukraine, uncertainty looms over summer harvesting. Ukrainian farmers braved a war […]
Read MoreHow fast a row of dominoes topples depends on friction
It may seem like fun and games, but understanding how dominoes topple isn’t child’s play. “It’s a problem that is so natural; everybody plays with dominoes,” says David Cantor, a researcher at Polytechnique Montreal with a background in civil engineering. So Cantor set out to create computer simulations of a row of dominoes collapsing in […]

Solution to performance stalemate means tidal rivers’ vast electrochemical power could be harnessed
Read MoreRobotic lightning bugs take flight
Inspired by fireflies, researchers created soft actuators that can emit light in different colors or patterns. These artificial muscles, which control the wings of featherweight flying robots, light up while the robot is in flight, which provides a low-cost way to track the robots and also could enable them to communicate.
