SMU geophysicists have used satellite imagery to identify more than 600 slow-moving landslides occurring near the U.S. West Coast

Researchers from Skoltech and the University of Southampton, U.K., have used all-optical methods to create an artificial lattice whose nodes house polaritons—quasiparticles that are half-light and half-matter excitations in semiconductors. This so-called Lieb lattice, which usually does not occur in nature, enabled the team to demonstrate breakthrough results important for condensed matter physics. From the applications perspective, the laser-generated polariton lattice, reported in Nature Communications... Читать дальше...

A new Oregon State University study on foot-and-mouth disease among buffalo in South Africa could help explain how certain extremely contagious pathogens are able to persist and reach endemic stage in a population, long after they've burned through their initial pool of susceptible hosts.

Scientists at the University of Liverpool and Harvard Medical School have discovered a new defense mechanism that makes a lethal strain of Salmonella resistant to viral infection.

A group of scientists affiliated with the University at Albany and New York State Department of Health (NYSDOH) are predicting that the total number of West Nile virus (WNV) cases will increase, and be more geographically widespread, across New York and Connecticut in future years due to warming trends.

Just before midnight on Tuesday, Sept. 28, an independent, bipartisan commission voted to approve a new map for Colorado's congressional districts––dividing the state into eight territories with roughly equal populations.

For the endangered Hawaiian plant Eugenia koolauensis, fungi could be both its demise and its savior. The fungal pathogen myrtle rust (Austropuccinia psidii) has been devastating populations of the endemic tree, along with many other native and cultivated plants. However, researcher Mason Kamalani Chock thinks part of the solution might be more fungi.

The scientific description of the catastrophic rockslide of February 7, 2021, in India's Dhauli Ganga Valley reads like a forensic report. A rockslide and the subsequent flood had killed at least 100 people and destroyed two hydroelectric power plants. In the scientific journal Science, researchers from the GFZ German Research Center for Geosciences (GFZ) together with colleagues from the National Geophysical Research Institute of India (NGRI), trace the disaster minute by minute using data from a network of seismometers.

Engaging students through interactive activities, discussions, feedback and AI-enhanced technologies resulted in improved academic performance compared to traditional lectures, lessons or readings, faculty from Carnegie Mellon University's Human-Computer Interaction Institute concluded after collecting research into active learning.

New research involving Lawrence Livermore National Laboratory (LLNL) scientists shows that water can remain liquid in a metastable state when transitioning from liquid to a dense form of ice at higher pressures than previously measured.

Researchers at the University of Illinois Urbana-Champaign can now rapidly isolate and chemically characterize individual organelles within cells. The new technique tests the limits of analytical chemistry and rapidly reveals the chemical composition of organelles that control biological growth, development and disease.

When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn't always believing.

Smartphone sensors are used daily to detect time and travel, but when those two factors are combined, researchers found that these sensors can also detect a cannabis high.

Scientists have long debated how much molecular oxygen was in Earth's early atmosphere. About 2.4 billion years ago, there was a rise in oxygen that transformed Earth's atmosphere and biosphere, eventually making life like ours possible. This transition is called the "Great Oxidation Event." But how much oxygen was in the atmosphere before this time?

A pioneering technique developed by the Prevedel Group at EMBL allows neuroscientists to observe live neurons deep inside the brain – or any other cell hidden within an opaque tissue. The technique is based on two state-of-the-art microscopy methods, three-photon microscopy and adaptive optics. The paper reporting on this advancement was published on 30th September 2021 in Nature Methods.

Poisonous algae blooms are becoming more common in the US, threatening water supplies and public health. But so far, there are few state or federal guidelines, and local water managers could use some help, a UConn-led team of researchers reports in the September 30 issue of Nature Sustainability.

New RAND Corporation research finds that 491,000 children from Mexico and the Northern Triangle (Honduras, Guatemala, El Salvador) arrived in the United States between fiscal years 2017 and 2019 and remained with unresolved immigration statuses. Of these, 321,000 were enrolled in U.S. K-12 public schools as of March 2020. About 75% settled in California, Texas, Florida, New York, Virginia, Maryland, New Jersey, Georgia, North Carolina and Louisiana.

Cancer immunotherapy seeks to turn "cold" tumors into "hot" tumors––those that respond to immunotherapy––by awakening and enlisting the body's own immune system.

As its name suggests, the bigleaf maple tree's massive leaves are perhaps its most distinctive quality. A native to the Pacific Northwest's wet westside forests, these towering trees can grow leaves up to 1.5 feet across—the largest of any maple.

Vast ammonites, relatives of squid and octopus, up to 1.8 meters across once littered the East Sussex seas, according to new research.

The COVID-19 pandemic continues to be a stark reminder of the importance of keeping lines of communication open between scientists and the lay public and the dangers of failing to do so.

Many investors compare Bitcoin to gold as a store of value, even referring to Bitcoin as "digital gold," a comparison believed to be one of the drivers of Bitcoin's meteoric rise over the past several months.

Florida State University researchers have found that some marine-protected areas may not work as predicted in safeguarding and conserving endangered species.

When Nicole Oliveira was just learning to walk, she would throw up her arms to reach for the stars in the sky.

A paper published today in the journal Nature Energy identifies five ways that people of high socioeconomic status have a disproportionate impact on global greenhouse gas emissions—and therefore an outsized responsibility to facilitate progress in climate change mitigation.
