A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this …

A new robotic suction cup which can grasp rough, curved and heavy stone, has been developed by scientists.

A new typing model simulates the typing process instead of just predicting words.

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. Researchers, using an experiment that elucidated the function of tens of thousands of noncoding variants, discovered a link between functional mutation…

The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.

Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and ca…

The energy density of supercapacitors — battery-like devices that can charge in seconds or a few minutes — can be improved by increasing the ‘messiness’ of their internal structure. Researchers used experimental and computer modelling techniques to s…

Scientists have discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s. Anticipated as future bits in computer memory, these nanobubbles offer enhanced avenues for informat…

Land subsidence is overlooked as a hazard in cities, according to new research. Scientists used satellite data that accurately and consistently maps land movement across China.

Scientists have developed artificial heterostructures made of freestanding 2D and 3D membranes that have an energy density up to 19 times higher than commercially available capacitors.

Researchers have uncovered a mechanism in the brain that allows cocaine and morphine to take over natural reward processing systems.

The annual influenza vaccine has become less effective on average over time. One reason may be reduced vaccine efficacy in people with obesity than those with a healthier body mass index (BMI), while the number of people with high BMI grows. Findings s…
