Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window into the universe. To observe them, ultra-precise detectors are required. Designing them remains a major scientific challenge for humans. Researchers have been working on how an artificial intelligence […]

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. Researchers are developing a new hydrogel-based material that makes it possible to engineer artificial skin tissues, which can serve as living three-dimensional models of human skin for better understanding and treating skin diseases.

Researchers have developed a machine learning workflow to optimize the output force of photo-actuated organic crystals. Using LASSO regression to identify key molecular substructures and Bayesian optimization for efficient sampling, they achieved a maximum blocking force of 37.0 mN — 73 times more efficient than conventional methods. These findings could help develop remote-controlled actuators for

A researcher has analyzed the most frequent situations faced by football goalkeepers. The aim is to compile data to facilitate the design of more effective training. The work stresses the importance of practicing the deflections and first touch shots that are produced.

Researchers have demonstrated a way to use corn protein to improve the performance of lithium-sulfur batteries, a finding that holds promise for expanding the use of the high-energy, lighter-weight batteries in electric vehicles, renewable energy storage and other applications.

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet’s unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its imprint is strongest in the southern hemisphere. Researchers found that Mars could have produced a one-sided magnetic field with a fully molten core, rather

Researchers share a model that identifies the optimal location for bowling ball placement. Employing a system of six differential equations derived from Euler’s equations for a rotating rigid body, their model creates a plot that shows the best conditions for a strike. The model accounts for a variety factors, including the thin layer of oil

A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is only 73 light years from Earth and could serve as a ‘Rosetta Stone’ for understanding an entire class of

Ambisonic rendering is a way to simulate the precise locations of sounds in 3D, and an ambisonics algorithm has allowed researchers to create rich virtual ‘soundscapes.’Researchers decided to test the limits of ambisonic sound reproduction through their ‘AudioDome’ loudspeaker array. Humans’ spatial acuity is high in front of our faces but decreases around the sides

Researchers use mathematical modeling to probe whether cohesive communities are more resilient to extreme events, finding that emotional intensity and levels of stress play a big role.
