Two highly similar molecules with essential but often contrasting signaling roles in most life forms exert their distinct effects through subtle differences in their bindings to their signaling partners, according to a new study led by researchers at Weill Cornell Medicine.

Cameras used in harsh environments must be designed in a way that prevents temperature swings from influencing their optical performance. New research demonstrates that accounting for the exact lens mounting structure used is a critical step in ensuring that lens systems remain robust to temperature changes.

Hundreds of miles north of the Arctic Circle, Sandia National Laboratories researchers ensure the collection of important weather and climate data. By switching the gas used in their weather balloons, they have reduced their metaphorical footprint on the fragile Arctic ecosystem.

A mysterious trail of stars formed eight thousand million years ago and recently discovered by the Hubble Space Telescope has been a challenge to a number of research groups. Its size is similar to that of the Milky Way, and this very long narrow structure has given rise to several explanations of its origin.

Cattle worldwide face major health threats from a highly infectious viral disease that decades of vaccinations and other precautions have failed to contain. Federal, private-sector and University of Nebraska-Lincoln scientists are collaborating on a new line of defense, by producing a gene-edited calf resistant to the virus.

The National Institute for Materials Science (NIMS) has achieved a tunnel magnetoresistance (TMR) ratio of 631% at room temperature, breaking the previous world record, which had stood for 15 years.

A metallic object believed to be a meteorite punched a hole in the roof of a central New Jersey home this week, smashing into a hardwood floor and bouncing around a bedroom. The family who owns the home discovered the black, potato-sized rock in a corner—still warm.

Philip Skemer, associate department chair and professor of Earth and planetary sciences, and graduate student Charis Horn, both in Arts & Sciences at Washington University in St. Louis, have published a study in Geophysical Research Letters that showcases the power and potential of the large volume torsion (LVT) apparatus.

In a paper published today, researchers from the Randall Centre for Cell & Molecular Biophysics and The Crick use an evolutionary cell biology approach in two related fission yeasts, one that acquires energy by respiration and one that doesn't, to find the critical points at which respiration feeds into central carbon metabolism.

Researchers Charlotte de Mouzon and Gérard Leboucher of the Laboratoire Ethologie Cognition Développement, Université Paris Nanterre in France, have examined preferred feline etiquette when faced with an unfamiliar human. In the paper, "Multimodal Communication in the Human–Cat Relationship: A Pilot Study," published in Animals, researchers examined four modes of human interactions—vocal,...

A research group at the University of Cordoba characterizes a new transcription factor that regulates, during the ripening of strawberries, the production of anthocyanins responsible for giving them their red hue.

A team of researchers at Aalto University has developed a new tool to help urban planners keep urban developments in line with climate goals. The tool provides a metric that planners can use to improve carbon-neutral planning of urban growth, which is essential for meeting carbon emission targets.

Making uniform decisions to justify the decommissioning of offshore artificial structures at the end of their lives could pose significant environmental challenges, a new study has said.

Partisan conflict can be largely explained as differing views on two crucial tasks of society, according to a new theory developed by a pair of prominent social scientists.

Fiber-optic cables line the coasts of the continents and crisscross the oceans, carrying signals that are the backbone of communication in the modern world. While their main job is telecommunications, researchers have been exploring ways to use this giant network to eavesdrop on everything from storms to earthquakes to whales.

Attitudes about gun violence and firearm policies are influenced by race more than age, and opinions vary widely based on whether respondents were born in the U.S. and their political affiliation, according to a recent University of Maryland Critical Issues Poll conducted with Ipsos.

Decades of industrial agriculture have caused environmental and social damage across the globe. Soils have deteriorated and plant and animal species are disappearing. Landscapes are degraded and small-scale farmers are struggling. It's little wonder we're looking for more sustainable and just ways of growing food and fiber.

A team of scientists from the University of Ottawa has developed an innovative technique to manufacture complex chemical structures from easily accessible substrates, making it one of the simplest and most practical methods for converting alcohols into their arylated equivalents.

Protecting lions and the interests of cattle producers in Kenya is a difficult balancing act. In a recent Frontiers in Ecology and Evolution article, Dr. Laurence G Frank, a researcher at the Museum of Vertebrate Zoology at the University of California, Berkeley, and the Mpala Research Centre in Laikipia, Kenya, explored how protecting livestock can help protect endangered lions.

Just four years ago, the Spanish Supreme Court pointed out in a ruling that there is no such thing as a "conjugal debt." In other words, a woman is not obliged to satisfy her husband's sexual needs. It may come as a surprise that this point still needs to be made, but the statistics speak for themselves. According to a national survey carried out in 2019, 7.5% of Spanish women over 16 years old...

The theory that aquatic animals such as fish will shrink due to global warming has been called into question by a study published today in eLife.

The precision of obtaining abundant light-matter-interact information with a snapshot measurement makes optical spectroscopy indispensable for modern industries and scientific research. The miniaturization of traditionally bulky spectrometers has been strongly motivated by the vast applications, including bio/medical sensing, material analysis, optical communication, and light source...

Geothermal energy, found in subsurface hot dry rocks, is a viable option instead of fossil fuels. Enhanced geothermal systems (EGS) enable us to use the plentiful amounts of energy in the hot rocks. The optimization and risk management of this process necessitate the accurate predictions of long-term thermal performance under different scenarios, which are usually done through numerical modeling.

Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular "mother tree hypothesis." An international group of researchers re-examined the evidence for and against this...
