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, the study authors found.

Thousands of dead fish and other marine life carcasses are washing ashore in the San Francisco Bay Area, creating a foul smell. Experts point to an unprecedented "red tide" algae bloom as the mostly likely cause.

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 insulators, in which the electrons cannot move around, but the spin remains controllable. In these materials... Читать дальше...

A new study has found that "diamond rain," a long-hypothesized exotic type of precipitation on ice giant planets, could be more common than previously thought.

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 which enable people with disabilities' inclusion.

African countries on Friday agreed on a common push to limit global warming to 1.5 degrees Celsius—a goal that scientists fear is increasingly elusive—at upcoming UN climate talks.

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.

African swine fever (ASF) is a highly infectious and fatal disease of pigs. Due to the complexity of the ASF virus (ASFV) and various clinical forms of the disease, a wide range of highly effective and robust sero-diagnostic assays are required.

Families hosting weddings near Baton Rouge, Louisiana, have 156 florists from which to choose, according to online registry The Knot.

UC Riverside scientists are on the hunt for a chemical that disrupts "evil" weevils' mating and could prevent them from destroying California's supply of avocados.

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.

Vinyl polymerization (polymerization of vinyl compounds) is a useful method for preparing sp3-carbon-based main-chain polymers including commodity plastics, where the polymer backbone is constructed from a two-carbon unit derived from vinyl groups of monomers.

The first-ever detailed study of climate anxiety among the UK adult population suggests that whilst rates are currently low, people's fears about the future of the planet might be an important trigger for action when it comes to adapting our high-carbon lifestyles to become more environmentally friendly.

An unusual protein structure known as a "rippled beta sheet," first predicted in 1953, has now been created in the laboratory and characterized in detail using X-ray crystallography.

Did the first ancestors of whales pick up where the mosasaurs left off 66 million years ago, after the extinction of all the large predatory marine reptiles?

The introduction of topology in photonic systems has attracted considerable attention not only for the elaborate molding of light but also for its practical applications in novel photonic devices. Originally, the quantum Hall effect of light was realized in photonic crystals (PCs) by introducing external electric or magnetic fields to break the time-reversal symmetry (TRS).

When eight-year-old Hugo Deans discovered a handful of BB-sized objects lying near an ant nest beneath a log in his backyard, he thought they were a type of seed. His father, Andrew Deans, professor of entomology at Penn State, however, knew immediately what they were—oak galls, or plant growths triggered by insects. What he didn't realize right away was that the galls were part of an elaborate relationship among ants, wasps and oak trees, the discovery of which would turn a century of knowledge about plant-insect interactions on its head.

Shouldn't common provisions for procurement within the EU lead to increased central control and better coordination? Yes, but the guidelines introduced during the COVID-19 crisis were at the same time so flexible that they can also result in increased corruption and reduced legitimacy. This is shown by Brigitte Pircher, associate professor of political science, in a new research article.

The research team of the Red List of Mammals in Portugal, which is working on reviewing the threat and conservation status of these species in this country, carried out an "unprecedented compilation" of data on georeferenced occurrences of mammals in mainland Portugal and the Azores and Madeira.

Everyone knows that trees provide shade. What may be less obvious are their contributions to evaporative cooling. Think of tree roots drawing water from the ground and pumping it to their leaves, which effectively sweat H2O, cooling the air around them in the process.

New research provides fresh insight into how an important class of molecules are created and moved in human cells.

A multidisciplinary team of Indiana University researchers have discovered that the motion of chromatin, the material that DNA is made of, can help facilitate effective repair of DNA damage in the human nucleus—a finding that could lead to improved cancer diagnosis and treatment. Their findings were recently published in the Proceedings of the National Academy of Sciences.

Innovations that make the food supply chain more "responsible"—eco-friendly, good for public health, fairer to farmers—will come faster if the contexts that set the stage for them are better understood, according to a new Université de Montréal study.

New York City is girding itself for storm season, which, in the face of accelerating climate change, could mean more frequent and extreme storms like Hurricanes Henri and Ida, and local cloudbursts producing prodigious volumes of stormwater.

A joint research team led by Dr. Jingkun Jiang from Tsinghua University and Dr. Markku Kulmala from the University of Helsinki has reported an efficient mechanism for gaseous sulfuric acid and bases to form atmospheric ultrafine particles. The findings explain the rapid formation of secondary ultrafine particles, which could further influence air quality and the climate.
