A systematic procedure is reported for calculating effective carrier lifetimes in semiconductor crystals from first-principles calculations. Consideration of three major recombination mechanisms and the use of realistic carrier and defect densities is key in …

A new Bayesian analysis of remote work data supports one of the oldest theories in social networks, with fresh implications for the future of work environments.

Alterations in cholesterol homeostasis may contribute to hepatic cancer aggressiveness. Liu, Tian, and Zhang et al. identify the long non-coding RNA SNHG6 as an important player in this process by linking cholesterol sensing with cancer cell growth through mT…

Lasers are everywhere. Devices that use them transmit information and enable the existence of long-distance communications and the internet; they aid doctors performing surgeries and engineers manufacturing advanced tools and technologies; and day-to-day, we …

It isn't alive, and has no structures even approaching the complexity of the brain, but a compound called vanadium dioxide is capable of 'remembering' previous external stimuli, researchers have found.

EPFL researchers have discovered that Vanadium Dioxide (VO2), a compound used in electronics, is capable of "remembering" the entire history of previous external stimuli. This is the first material to be identified as possessing this property, although there …

A new device can detect Parkinson's disease just from breathing patterns. The device, developed by a team led by Dina Katabi of MIT, employs a neural network to discern the presence and severity of the neurological disease.

A team of researchers at Iowa State University has found that it may be possible to grow alfalfa successfully on Mars. The group has written a paper describing their work and have published it on the open-access site PLOS ONE.

How will the James Webb Space Telescope study planets beyond our Solar System?

Chirality describes a molecule that can't be superimposed on its own mirror image. Two geometrically different chiral molecules of the same formula, distinguished by the R- and S- configuration, exhibit different optical properties. More intriguingly, a mater…

NASA has identified 13 possible landing sites near the moon’s south pole which will be used by the Artemis III mission which will bring humans to the moon’s ...

Epaulette sharks, found in the Great Barrier

By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology.

ISME Communications - Arm race among closely-related carbapenem-resistant Klebsiella pneumoniae clones

NASA has selected four mission concepts for additional research in the latest round of its astrophysics program, but budget constraints may cause some

The Sun will engulf nearby planets like Mercury, Venus and Earth during its last years. Here’s what will happen.

Scientific Reports - RSPO3 is a novel contraction-inducible factor identified in an “in vitro exercise model” using primary human myotubes

Comet 67P/Churyumov-Gerasimenko is rich in organic molecules that play a key role in the development of carbon-based life.

A new study connected the seismic data from NASA's Mars InSight mission to the properties of rocks, sediments, and ice on the red planet. Here's what has been revealed.

For nearly a century, University of Michigan librarians thought their Galileo manuscript was “one of the great treasures” of their collection.

An ancient piece of Earth’s crust was found underneath the South-West of Western Australia.

Two fundamental factors affect all astrophotography—timing and location. If a camera happens to be at the right place at the right time, it can capture images that have never been seen before. And with the proliferation of cameras throughout the solar system,…

The flow of time from the past to the future is a central feature of how we experience the world. But precisely how this phenomenon, known as the arrow of time, arises from the microscopic interactions among particles and cells is a mystery—one that researche…

These peculiar benthic sharks use their fins to walk on the surface, and they can survive in oxygen-deficient conditions for about two hours.

Following the discovery of a second impact crater off the coast of Africa, we might have to rethink the end of the Cretaceous period.
