Scientists from Russia, Austria, and the USA have discovered virus-like particles in the bacterial symbionts of Bryozoa—a phylum of colonial aquatic invertebrates—filter-feeders dominating in many bottom ecosystems. The research project was planned and supervised by scientists from St Petersburg University. Some of the virus-like particles resemble red blood cells, while others have a sea-urchin-like appearance. Although viruses have never been reported inside symbiotic bacteria in bryozoans, scientists... Читать дальше...

In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA's Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning it emits regular pulses of light.

Media coverage that focuses on strategy over issues can harm the electoral success of Senate candidates, according to wide-ranging research gauging news coverage of more than 150 Senate races in the United States in recent years.

The COVID-19 pandemic is raising fears of new pathogens such as viruses or drug-resistant bacteria. On this note, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant bacteria by controlling the surface texture of nanomaterials.

In a study published in Advanced Materials, researchers from Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China of the Chinese Academy of Sciences, using an electron-proton co-doping strategy, invented a new metal-like semiconductor material with excellent plasmonic resonance performance. This material achieves a metal-like ultrahigh free-carrier concentration that leads to strong and tunable plasmonic field.

Natural climate phenomena El Nino and La Nina are opposite phases of a complex weather pattern so powerful that it can alter the global temperature.

In a new book launched this week, Professor Helen Spencer-Oatey of the University of Warwick Department of Applied Linguistics and her co-author Professor Dániel Z. Kádár of the Hungarian Research Institute for Linguistics (NYTI) explore how people relate across cultural boundaries, a topic which is increasingly important in our interconnected world.

A team of researchers from the University of Chicago and Emory University has found evidence of a hydrogen bond/covalent bond hybrid. In their paper published in the journal Science, the group describes experiments they conducted with bifluoride ions that blurred the line between hydrogen bonds and covalent bonds. Mischa Bonn and Johannes Hunger with the Max Planck Institute for Polymer Research have published a Perspectives piece in the same journal issue outlining the work by the team on this new effort.

Doctors often tell us, "cut back on your salt." And just as too much dietary salt is bad for blood pressure, too much salt in our nation's streams, lakes, and reservoirs threatens ecosystem health and the security of our nation's drinking water and food supplies.

The first Philippine eagle bred in captivity in an effort to save one of the world's most endangered birds has died from infections, conservationists said Friday.

New probes allow scientists to see four-stranded DNA interacting with molecules inside living human cells, unraveling its role in cellular processes.

As much as one billion tons of waste could be burned in open and uncontrolled fires around the world each year, according to one estimate – close to half of all the municipal solid waste generated on Earth. But even if the true total is a fraction of that amount, the impact on human health and the environment is likely to be profound, particularly for the hundreds of millions of people living in countries throughout the global south where burning rubbish outdoors is the main method of waste treatment.

A team of researchers affiliated with institutions in Australia, the U.S. and France has found evidence of relatively recent water movement in meteorites that only recently collided with the Earth. In their paper published in the journal Science, the group describes their study of carbonaceous chondrite (CC) meteorites that landed on the surface of the Earth within the past century and what they found.

New Curtin University research has found a dramatic increase in people's trust in government in Australia and New Zealand as a result of the COVID pandemic.

The economist John Maynard Keynes predicted in 1930 that the amount we work would gradually shrink to as little as 15 hours a week as technology made us more productive. Not only did this not happen, but we also began to spend extra time away from home due to commuting and suburban living patterns, which we often forget are recent historical inventions.

The Sachdev-Ye-Kitaev (SYK) model, an exactly solvable model devised by Subir Sachdev and Jinwu Ye, has recently proved useful for understanding the characteristics of different types of matter. As it describes quantum matter without quasiparticles and is simultaneously a holographic version of a quantum black hole, it has so far been adopted by both condensed matter and high-energy physicists.

Researchers from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences developed a method termed SCRaMbLE-based genome compaction (SGC) to revamp and minimize the yeast genome.

Researchers from CAS Key Laboratory of Quantum Information of the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences have demonstrated on-demand storage of photonic qubits in an integrated solid-state quantum memory for the first time. This work was published in Physics Review Letters.

Type Ia supernovae, as cosmological distance indicators, have led to the discovery of the accelerating expansion of the Universe. Nevertheless, the nature of their progenitors and explosion mechanisms remain unsolved mysteries.

Carbon dioxide levels in the atmosphere will this year reach levels 50 percent higher than before the industrial revolution because of manmade emissions, Britain's Met Office predicted on Friday.

2020 has tied 2016 as the hottest year on record, the European Union's climate monitoring service said Friday, keeping Earth on a global warming fast track that could devastate large swathes of humanity.

The "Executive Order on Promoting American Seafood Competitiveness and Economic Growth," issued by the Trump administration in May 2020, lays out a plan to expand the U.S. seafood industry, especially aquaculture, and enhance American seafood competitiveness in the global market.
