Stellar collisions produce strange, zombie-like survivors
Densely packed, fast-moving stars at the Milky Way's center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like 'violent high fives' while others are full-on mergers.
Discovery of how limiting damage from an asthma attack could stop disease
Scientists have discovered a new cause for asthma that sparks hope for treatment that could prevent the life-threatening disease.
Evolution in action? New study finds possibility of nitrogen-fixing organelles
A new study finds that UCYN-A, a species of nitrogen-fixing cyanobacteria, may be evolving organelle-like characteristics.
Early dinosaurs grew up fast, but they weren't the only ones
The earliest dinosaurs had rapid growth rates, but so did many of the other animals living alongside them, according to a new study.
Researchers map how the brain regulates emotions
A new study is among the first of its kind to separate activity relating to emotion generation from emotion regulation in the human brain. The findings provide new insights that could help inform therapeutic treatments regarding mental health and drug addiction.
'Smart swarms' of tiny robots inspired by natural herd mentality
Researchers gave nanorobots a trait called adaptive time delay, which allows them to better work together.
Discovery could end global amphibian pandemic
A fungus devastating frogs and toads on nearly every continent may have an Achilles heel. Scientists have discovered a virus that infects the fungus, and that could be engineered to save the amphibians.
Plastic-free vegan leather that dyes itself grown from bacteria
Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
Intelligent liquid
Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres -- between 50 to 500 microns -- that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers th...
First results from BREAD experiment demonstrate a new approach to searching for dark matter
One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.
Australia on track for unprecedented, decades-long megadroughts
Australia could soon see megadroughts that last for more than 20 years, according to new modelling. The researchers' bleak findings are before factoring in human impact on the climate since the Industrial Revolution. According to the scientists, the findings paint a worrying picture of future droughts in Australia that are far worse than anything in recent experience.
100 kilometers of quantum-encrypted transfer
Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- roughly equivalent to the distance between Oxford and London.
We've had bird evolution all wrong
Genomic anamolies dating back to the time of the dinosaurs misled scientists about the evolutionary history of birds.
I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans
Using a blink-and-you'll-miss-it experiment, researchers have discovered that individuals differ widely in the rate at which they perceive visual signals. Some people perceive a rapidly changing visual cue at frequencies that others cannot, which means some access more visual information per timeframe than others. This discovery suggests some people have an innate advantage in certain settings where response time is crucial, such as in ball sports, or in competitive gaming.
Universal brain-computer interface lets people play games with just their thoughts
Engineers have created a brain-computer interface that doesn't require calibration for each user, paving the way for widespread clinical applicability.
Chatbot outperformed physicians in clinical reasoning in head-to-head study
ChatGPT-4, an artificial intelligence program designed to understand and generate human-like text, outperformed internal medicine residents and attending physicians at two academic medical centers at processing medical data and demonstrating clinical reasoning.
Researchers produce grafts that replicate the human ear
Using state-of-the-art tissue engineering techniques and a 3D printer, researchers have assembled a replica of an adult human ear that looks and feels natural. The study offers the promise of grafts with well-defined anatomy and the correct biomechanical properties for those who are born with a congenital malformation or who lose an ear later in life.
