'Oumuamua one year later
One year ago this week astronomers discovered an unusual object moving through space not too far from the Earth's orbit. In just a few days they realized it could not be a normal asteroid or comet – its path showed that ...

Mars likely to have enough oxygen to support life: study
Salty water just below the surface of Mars could hold enough oxygen to support the kind of microbial life that emerged and flourished on Earth billions of years ago, researchers reported Monday.

Fracking wastewater accumulation found in freshwater mussels' shells
Elevated concentrations of strontium, an element associated with oil and gas wastewaters, have accumulated in the shells of freshwater mussels downstream from fracking wastewater disposal sites, according to researchers from ...
Gravitational waves could shed light on dark matter
The forthcoming Laser Interferometer Space Antenna (LISA) will be a huge instrument allowing astronomers to study phenomena including black holes colliding and gravitational waves moving through space-time. Researchers from ...
Researchers switch material from one state to another with a single flash of light
Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Massachusetts Institute of Technology have demonstrated a surprisingly simple way of flipping a material from one state into another, ...
Astronomers propose a new method for detecting black holes
A stellar mass black hole is a compact object with a mass greater than three solar masses. It is so dense and has such a powerful force of attraction that not even light can escape from it. They cannot be observed directly, ...
Nanosized ferroelectrics become a reality
Using ferroelectricity instead of magnetism in computer memory saves energy. If ferroelectric bits were nanosized, this would also save space. But conventional wisdom dictates that ferroelectric properties disappear when ...
New algorithm can more quickly predict LED materials
Researchers from the University of Houston have devised a new machine learning algorithm that is efficient enough to run on a personal computer and predict the properties of more than 100,000 compounds in search of those ...
Mystery of how black widow spiders create steel-strength silk webs further unravelled
Researchers at Northwestern University and San Diego State University (SDSU) have better unraveled the complex process of how black widow spiders transform proteins into steel-strength fibers. This knowledge promises to aid ...
