Two women in Beaver Creek, Yukon, say they jumped on a lynx to pull it away from a dog it attacked on Saturday.
An elderly gorilla was recovering from a serious case of COVID-19 after he was treated with cutting-edge synthetic antibodies, the San Diego Zoo said Monday.
A major winter storm is threatening to blanket parts of the middle of the country with more than a foot of snow Monday, promising to disrupt travel and even forcing the closure of some coronavirus testing sites.
Massive earthquakes are, fortunately, rare events. But that scarcity of information blinds us in some ways to their risks, especially when it comes to determining the risk for a specific location or structure.
Research from North Carolina State University shows that extreme weather events, such as hurricanes and increased precipitation, affect both the amount and the composition of picophytoplankton in the Neuse River Estuary. The work is a first step in determining how a wetter climate may affect the estuarine ecosystem.
Every living organism has DNA, and every living organism engages in DNA replication, the process by which DNA makes an exact copy of itself during cell division. While it's a tried-and-true process, problems can arise.
A team led by plant biologists at the Universities of Freiburg and Göttingen in Germany has shown for the first time that mosses have a mechanism to protect them against cold that was previously known only in flowering plants. Professor Ralf Reski at the Cluster of Excellence Centre for Integrative Biological Signalling Studies (CIBSS) at the University of Freiburg and Professor Ivo Feussner at...
An extensive review of cephalopod fauna from the Northwest African Atlantic coast was performed by researchers from the University of Vigo (Spain) and the Spanish Institute of Oceanography (IEO). The study was based on the collections gathered in 1,247 bottom trawl stations carried out during ten multidisciplinary surveys in the Canary Current Large Marine Ecosystem (CCLME).
NASA is funding 30 awards across the U.S to implement the next phase of Science Activation—a community-based approach to connect NASA science with learners of all ages. The selected proposals will broaden participation of underrepresented and underserved learners, as well as expand connections with the agency’s scientists and engineers. Nine new awardees join a network of 21 that...
Scientists at the University of California, Irvine and NASA's Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland's fjords. Their work is the subject of a study published recently in Science Advances.
Employees feel significantly less job distress if they work at companies that are open and transparent about the firm's finances, including budgets and profits, a new study found.
Quantum physics allows to make statements about the behavior of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values, but are distributed over various values with certain probabilities. Often this distribution takes the form of a simple Gaussian bell curve that is encountered also in...
When it launches in the mid-2020s, NASA's Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and...
Nature is full of color. For flowers, displaying color is primarily a means to attract pollinators. Insects use their color vision not only to locate the right flowers to feed on but also to find mates. The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes. Casper van der Kooi, a biologist at the University of Groningen, uses an...
X-rays are usually difficult to direct and guide. X-ray physicists at the University of Göttingen have developed a new method with which the X-rays can be emitted more precisely in one direction. To do this, the scientists use a structure of thin layers of materials with different densities of electrons to simultaneously deflect and focus the generated beams. The results of the study were...
Dairy producers know early nutrition for young calves has far-reaching impacts, both for the long-term health and productivity of the animals and for farm profitability. With the goal of increasing not just body weight but also lean tissue gain, a new University of Illinois study finds enhanced milk replacer with high crude-protein dry starter feed is the winning combination.
Hernias are one of the most common soft tissue injuries. Hernias form when intra-abdominal content, such as a loop of the intestine, squeezes through weak, defective or injured areas of the abdominal wall.
Solar-driven photoelectrochemical (PEC) water splitting is an attractive approach to convert solar energy into chemical energy. Among many photoelectrode materials, crystalline silicon (c-Si) has drawn considerable attention because of its earth abundance, narrow bandgap, and suitable band edge position for hydrogen evolution reaction (HER). However, c-Si suffers from low photovoltage generated...
Halogen atoms (Cl and Br) strongly influence the atmospheric chemical composition. Since 1970s, scientists discovered that these atoms were responsible for depletion of ozone in the stratosphere and ground-level ozone of the Arctic. In the past decade, there is emerging recognition that halogen atoms also play important roles in tropospheric chemistry and air quality. However, the knowledge of...
The first people to settle in the Americas likely brought their own canine companions with them, according to new research which sheds more light on the origin of dogs.
Corals, like all animals, must eat to live. The problem is that most corals grow in tropical waters that are poor in nutrients, sort of like ocean deserts; it's this lack of nutrients that makes the water around coral reefs so crystal clear. Because food is not readily available, corals have developed a remarkable feeding mechanism that involves a symbiotic relationship with single-celled algae....
Gonadotropins are any hormones that are released from the anterior pituitary to stimulate the gonads, or sex glands, to carry out their reproductive functions. The gonadotropin-releasing hormone (GnRH) is therefore fundamental for mammalian reproduction. In a healthy reproductive system GnRH is produced by the brain in pulses. Reports suggest that at least 25% of ovarian disorders are due to...
