'Space waves' offer new clues to space weather

More accurate space-weather predictions and safer satellite navigation through radiation belts could someday result from new insights into "space waves," researchers at Embry-Riddle Aeronautical University reported.

How CEO political leanings affect their international deals

Conservative CEOs are four times more likely than their liberal counterparts to acquire international firms rather than forge new alliances when entering foreign markets, according to new research. The same study finds that these political biases can be moderated by active, independent boards.

Magnetic energy strings flex, wiggle and reconnect in a nanomagnetic array

A multi-institutional team exploring the physics of collective behavior has developed and measured a model nanomagnetic array in which the behavior can be best understood as that of a set of wiggling strings. The strings, which are composed of connected points of high energy among the lattice, can stretch and shrink, but also reconnect. What makes these strings special is that they are limited to...

Study of Uranus' large moons shows four may hold water

Re-analysis of data from NASA's Voyager spacecraft, along with new computer modeling, has led NASA scientists to conclude that four of Uranus' largest moons likely contain an ocean layer between their cores and icy crusts. Their study is the first to detail the evolution of the interior makeup and structure of all five large moons: Ariel, Umbriel, Titania, Oberon, and Miranda. The work suggests...

Tribe signs pact with California to work together on efforts to save endangered salmon

A California tribe has signed agreements with state and federal agencies to work together on efforts to return endangered Chinook salmon to their traditional spawning areas upstream of Shasta Dam, a deal that could advance the long-standing goal of tribal leaders to reintroduce fish that were transplanted from California to New Zealand more than a century ago and still thrive there.

New tool monitors Wikipedia page views to aid wildlife conservation efforts

Researchers have developed a new tool that tracks the monthly changes in Wikipedia page views for thousands of species. The Species Awareness Index (SAI) is designed to provide a real-time measure of changing interest in biodiversity that can help conservation organizations and science communicators develop effective strategies for protecting wildlife. The study, "Achieving a real-time online...

Research exposes differences between how men and women compete against each other

It is well understood that in the labor market there exist wage gaps between men and women, and in general, women have had to fight to break the "glass ceiling" to get to upper management in the workplace. The causes of the gender gap may be multiple factors from discrimination to ability difference, and it is not easy to separate one from the other.

Radiation damage simulation software developed for defect accumulation mechanisms study in polycrystalline materials

Recently, the research group led by Prof. Liu Changsong from Institute of Solid State Physics (ISSP), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) developed a set of software for simulating the evolution of displacement damage in polycrystalline metals at across time and space scales, which was named object kinetic Monte Carlo-lattice kinetic Monte Carlo...

High school students learn the basics of base editing to cure 'GFP-itis'

Genome editing is used to modify the genes of living organisms to elicit certain traits, such as climate-resilient crops or treating human disease at the genetic level. It has become increasingly popular in agriculture, medicine and basic science research over the past decade, and will continue to be relevant and utilized well into the future. Given this prevalence, researchers at the University...
