Humans have them, so do other animals and plants. Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth.

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...

New research led by the University of South Florida has uncovered one of the reasons jellyfish have come to be known as the "world's most efficient swimmer." Brad Gemmell, associate professor of integrative biology, found jellyfish produce two vortex rings, which are donut-shaped bodies of fluid underneath their translucent bodies, that spin in opposite directions. They appear as jellyfish squeeze...

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.

Maize has a significantly higher productivity rate compared with many other crops. The particular leaf anatomy and special form of photosynthesis (referred to as C4) developed during its evolution allow maize to grow considerably faster than comparable plants. As a result, maize needs more efficient transport strategies to distribute the photoassimilates produced during photosynthesis throughout...

When Michigan State University's Gemma Reguera first proposed her new research project to the National Science Foundation, one grant reviewer responded that the idea was not "environmentally relevant."

Scientists have figured out a cheaper, more efficient way to conduct a chemical reaction at the heart of many biological processes, which may lead to better ways to create biofuels from plants.

In a study published in Physical Review Letters, a team led by academician Guo Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has made progress in high dimensional quantum teleportation. The researchers demonstrated the teleportation of high-dimensional states in a three-dimensional six-photon system.

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...

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...

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.

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...

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

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...

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.

Scientists sequencing virus samples from the first confirmed cases of COVID-19 in Scotland (and through the first wave) have found evidence of community transmission, driven by multiple introductions through international travel, as early as February 2020.

An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The results have been published in the journal PLOS Genetics.

Climate change is harming many special places and iconic species around our planet, from Glacier National Park's disappearing glaciers to California redwoods scorched by wildfires. But for the animal I study, the American pika (Ochotona princeps), there's actually some good news: It's not as threatened by climate change as many studies have warned.
