A coronavirus uses protein "spikes" to grab and infect cells. Despite their name, those spikes aren't stiff and pointy. They're shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every ...
When mammals have offspring, they invest a lot. Unlike fish or frogs, the embryo cannot develop on its own. It has to implant in the uterus, where it is supplied with everything it needs to survive. Until this happens, the ...
Atrial fibrillation, heart failure and stroke—hypertrophic cardiomyopathy can lead to many serious health conditions and is a major cause of sudden cardiac death in people younger than 35.
Imagine the life of a yeast cell, floating around the kitchen in a spore that eventually lands on a bowl of grapes. Life is good: food for days, at least until someone notices the rotting fruit and throws them out. But then ...
A sample collected from the 4.5-billion-year-old asteroid Bennu contains abundant water and carbon, NASA revealed on Wednesday, offering more evidence for the theory that life on Earth was seeded from outer space.
Tinkerer though he is, Peter Dahlberg did not spend the last few years tearing apart a $1.5 million microscope just for fun.
The LHC is back delivering collisions to the experiments after the successful leak repair in August. But instead of protons, it is now the turn of lead ion beams to collide, marking the first heavy-ion run in five years.
Scientists at the National Institute of Standards and Technology (NIST) with colleagues elsewhere have employed neutron imaging and a reconstruction algorithm to reveal for the first time the 3D shapes and dynamics of very ...
As the number of cores in a processor continues to grow, so too does the challenge of connecting them all together. Traditional electrical networks fall short due to latency, limited bandwidth, and high-power consumption. ...
The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method.
