Fur traps fingered as source of grizzly injuries

In 2016, wildlife biologist Clayton Lamb was securing a GPS collar to a tranquilized grizzly bear in southeastern British Columbia when he noticed one of its paws was missing three toes. Weird, he remembers thinking, but not surprising for the rough-and-tumble animals. Then, three more grizzlies popped up sporting similarly mangled paws. Anxious to solve the mystery behind this grisly...

Exoplanets Have Been Impossible to Photograph Directly—Until Now

There’s nothing terribly special about the exoplanet known as HIP 65426 b. It’s a gas giant nine times the mass of Jupiter, orbiting its host star 385 light years from Earth. Just one of at least 5,000 exoplanets astronomers have detected, it could easily go overlooked. But, as NASA announced yesterday, HIP 65426 b is all at once very big news—becoming the first exoplanet...

Making nanodiamonds out of bottle plastic

What goes on inside planets like Neptune and Uranus? To find out, an international team conducted a novel experiment. They fired a laser at a thin film of simple PET plastic and investigated what happened using intensive laser flashes. One result was that the researchers were able to confirm their earlier thesis that it really does rain diamonds inside the ice giants at the periphery of our solar...

Artificial intelligence can be used to better monitor Maine's forests

Researchers have developed a novel method of using artificial intelligence and machine learning to make monitoring soil moisture more energy and cost efficient. The software learns over time how to make the best use of available network resources, which helps produce power efficient systems at a lower cost for large scale monitoring compared to the existing industry standards.

Conflictive home-host country relations have a strong, negative effect on policy risk

Policy risk negatively affects acquisition completion, but the strength of the effect is dependent on home-host country relations, according to new research published in Global Strategy Journal. The relationship between policy risk and cross-border acquisition completion is negative and strong under conflictive relations, weaker under cooperative relations, and weakest under ambivalent relations,...

Investigating magnetic excitation-induced spin current in chromium trihalides

An ingenious approach toward developing low-power, high-speed, and high-density memory devices is based on spintronics, an emerging frontier in technology that harnesses a degree of freedom of electrons known as spin. Put simply, electrons, along with their negative charge, possess a spin whose orientation can be controlled using magnetic fields. This is particularly relevant for magnetic...

New report on impact of pandemic on learning experiences of young people with disabilities

The first report to examine the impact of the COVID-19 pandemic on the learning experiences of young people with disabilities has been published. Researchers at University College Cork (UCC) examined how the COVID-19 pandemic has affected young people with disabilities' experience of learning and vocational training, and what we can learn from this about future education and employment practices...

What's the future of work from home?

With rapidly evolving technology, the COVID-19 pandemic and shifting priorities, there have been major changes in recent years in how employers and employees think about work.

EP-WXT pathfinder catches first wide-field snapshots of X-ray universe

EP-WXT Pathfinder, the experimental version of a module that will eventually be part of the wide-field X-ray telescope (WXT) aboard the astronomical satellite Einstein Probe (EP), released its first results Aug. 27 from an earlier test flight. These include an 800-second X-ray time-lapse photograph of a region of the Galactic center, a dense area at the core of our home galaxy, the Milky Way.

Sexual harassment plagues Antarctic research

The U.S. Antarctic research program is rife with sexual harassment and assault, according to a report released last week . Commissioned by the National Science Foundation (NSF), which manages the program, and written by an external firm, the report also found that those working in Antarctica largely don’t trust their employers to take harassment complaints seriously, to...
