A new method to measure the temperature of atoms during the explosive death of a star will help scientists understand the shock wave that occurs as a result of this supernova explosion. An international team of researchers, including a Penn State scientist, combined observations of a nearby supernova remnant—the structure remaining after a star's explosion—with simulations in order to measure the temperature of slow-moving gas atoms surrounding the star as they are heated by the material propelled outward by the blast.

Having ancestors who were frequently exposed to stressors can improve one's own immune response to stressors, according to Penn State researchers. The results suggest that family history should be considered to predict or understand the health implications of stress.

Divisions between EU countries could delay or derail plans to overhaul copyright law, an ambition that has set up a battle pitting media firms against internet giants like Facebook and Google.

Even though every other media company seems to be starting a streaming service, Netflix is facing an on-screen challenge from another corner: "Fortnite," that ultra-popular, multiplatform videogame, appears to be a formidable foe.

Despite all the controversies Facebook saw in 2018, with hackings, data breaches and a round of apologies, consumers never gave up on the social network.

Madrid taxi drivers began an open-ended strike Monday against online ride-hailing services like Uber, joining their counterparts in Barcelona who walked off the job three days ago.

A rapid rise in temperature on ancient Earth triggered a climate response that may have prolonged the warming for many thousands of years, according to scientists.

Facebook will expand its presence in Ireland with an additional 1,000 staff over 2019, the firm announced Monday, bolstering the tech giant's largest base outside of its California headquarters.

The piezoelectric materials that inhabit everything from our cell phones to musical greeting cards may be getting an upgrade thanks to work discussed in the journal Nature Materials released online Jan 21.

Electronics have advanced through continuous improvements in microprocessor technology since the 1960s. However, this process of refinement is projected to stall in the near future due to constraints imposed by the laws of physics. Some of these bottlenecks have already taken effect. For instance, the clock speeds of processors are have not exceeded a few gigahertz, or several operations per nanosecond, for the past 20 years, a limitation stemming from the electrical resistance of silicon. This has... Читать дальше...

When species compete for limited resources, structures in their environment can be the difference between coexistence or one eliminating another. Relationships between species also are important, according to new research by University of Oregon scientists.

Increasing consumption of meat rich diets throughout the world in the 21st century raises pressing concerns about human health, animal welfare and environmental sustainability. Too much mass-produced meat is bad for us, bad for the livestock we eat, and bad for the planet on which we live.

In 2017, in an ordinary field, two brothers from Brabant discovered more than 100 ancient coins. The Leiden historian who examined the coins concluded that they constituted a genuine Roman treasure. Here follows a reconstruction in three acts.

Since the birth of structural biology, X-ray crystallography has been the most widely used technique to determine the three-dimensional structure of biomolecules, the chemical compounds found in living organisms. In this regard, knowledge of the interactions between the biomolecules with their crystal environment and the molecular forces that stabilize the crystals would serve to optimise this technique.

A team of researchers has discovered a new process capable of generating resistance to synthetic antibacterial drugs within bacterial populations long before they are put to clinical use.

Paying a living wage could be a step toward global economic and environmental sustainability, finds a first-of-its-kind study by the University of Surrey.

A two to three-fold increase in heatwave activity in the United Kingdom since the late 19th century has been identified in a new analysis of historical daily temperature data led by University of Warwick scientists.

Graphene exhibits very different properties in humid conditions, according to researchers from Queen Mary University of London.

Researchers at the Center for Correlated Electron Systems, within the Institute for Basic Science (IBS) in South Korea, in collaboration with Sogang University and Seoul National University, reported the first experimental observation of a XY-type antiferromagnetic material, whose magnetic order becomes unstable when it is reduced to one-atom thickness. Published in Nature Communications, these findings are consistent with theoretical predictions dating back to the 1970s.

Using the Mobile Astronomical System of Telescope-Robots (MASTER), an international team of astronomers has detected a new eclipsing cataclysmic variable. The newfound object, designated MASTER OT J061451.70–272535.5, is most likely of the polar subclass. The finding is detailed in a paper published January 9 on arXiv.org.

The reintroduction program for the green turtle in the Cayman Islands is crucial for species recovery. The turtles are threatened by the effects of human overexploitation, according to a study published in the journal Molecular Ecology led by experts Marta Pascual and Carlos Carreras from the Evolutionary Genetics laboratory of the University of Barcelona.

David Crandall is an associate professor in the School of Informatics, Computing and Engineering at Indiana University Bloomington. He, Sara Skrabalak and Martin Swany are the first IU researchers whose work is being advanced through the Indiana Innovation Institute, or IN3.

If you've ever camped by a pond, you know frogs make a racket at night; but what you might not know is how functional and regulated their choruses really are. Frogs communicate with sound, and amid their ruckus is an internally orchestrated system that lets information get through more clearly while also permitting collective choruses and time to rest. Researchers from Osaka University and University of Tsukuba sought to leverage this amphibious acumen for mathematical and technological aims.

Plastic pollution in the world's oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.

Mercury is a highly toxic and pervasive pollutant that has dramatically increased in the environment as a result of coal combustion, gold mining, cement production, hospital waste incineration, and various other human activities around the globe. Its impacts on birds and other wildlife are not yet fully understood, but a new study published in the journal Environmental Pollution suggests that current levels of mercury contamination in many parts of the world are capable of compromising the ability of birds...
