Director retention does not necessarily facilitate post-acquisition firm performance: study
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books—the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen.
Astronomers seek evidence of tech built by aliens
Firm acquisition is a complicated process in which acquiring companies often try to smooth the transition by retaining at least one board-level director from the target company. New research from the University of Notre Dame calls into question the wisdom of this move.
What happens to marine life when oxygen is scarce?
An international team of scientists led by a prominent Harvard astronomer announced a new initiative Monday to look for evidence of technology built by extraterrestrial civilizations.
Through the thin-film glass, researchers spot a new liquid phase
In September 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in...
When a heat wave comes, this scientist takes a shellfish's perspective
Research published in the Proceedings of the National Academy of Sciences describes a new type of liquid in thin films, which forms a high-density glass. Results generated in this study, conducted by researchers in Penn's Department of Chemistry, demonstrate how these glasses and other similar materials can be fabricated to be denser and more stable, providing a framework for developing new...
ATLAS reports first observation of WWW production
Stepping into the gap between the rocks, it's easy to understand what Brian Helmuth is talking about.
Study: Countries' wealth inequality independent from income inequality, linked to distribution of housing equity
The ATLAS Collaboration at CERN announces the first observation of "WWW production": The simultaneous creation of three massive W bosons in high-energy Large Hadron Collider (LHC) collisions.
Astronomers uncover briefest supernova-powered gamma-ray burst
Most of what we know from prior research about which countries are more unequal than others is based on measures of income inequality. In their new study, "The Wealth Inequality of Nations," appearing in the August 2021 issue of the American Sociological Review, authors Fabian T. Pfeffer and Nora Waitkus show that comparing countries in terms of their wealth inequality instead of income inequality...
Researchers demonstrate technique for recycling nanowires in electronics
Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a program of NSF's NOIRLab, astronomers identified the cause of this 0.6-second flurry of gamma rays as a supernova explosion in a distant galaxy. GRBs caused by supernovae are usually more than twice as long, which suggests that some short GRBs...
India's poor face outsized air pollution death risk
Researchers at North Carolina State University have demonstrated a low-cost technique for retrieving nanowires from electronic devices that have reached the end of their utility, and then using those nanowires in new devices. The work is a step toward more sustainable electronics.
Record-shattering heatwaves caused by pace of warming: study
The poorest 10 percent of Indians face a risk of dying from air pollution that is nine times higher than for the richest 10 percent, according to research released Monday.
Large meteor lights up skies in Norway
Heatwaves that obliterate temperature records as in western Canada last month and Siberia last year are caused by the rapid pace, rather than the amount, of global warming, researchers said Monday.
Now in 3D: Deep learning techniques help visualize X-ray data in three dimensions
Norwegian experts say an unusually large meteor was visible over large parts of southern Scandinavia and illuminated southeast Norway with a powerful flash of light for a few seconds as many observers were reported to also hear a roaring sound afterwards.
Minnesota adopts 'clean car' rules requiring more electric vehicles
Computers have been able to quickly process 2D images for some time. Your cell phone can snap digital photographs and manipulate them in a number of ways. Much more difficult, however, is processing an image in three dimensions, and doing it in a timely manner. The mathematics are more complex, and crunching those numbers, even on a supercomputer, takes time.
Minnesota has become the latest state to adopt California's stricter standards for tailpipe emissions and a mandate for automakers to get more zero-emission vehicles onto sales lot.
