Scientists who drilled deeper into an undersea earthquake fault than ever before have found that the tectonic stress in Japan's Nankai subduction zone is less than expected, according to a study from researchers at The University of Texas at Austin and University of Washington.
People's experiences of racism and stigma prior to coronavirus must be considered during any evaluation of the impact of social distancing, experts have said.
Workplace violence is a pervasive problem with tremendous costs for individuals, organizations, and society. A new study published this week in the Proceedings of the National Academy of Sciences (PNAS) focuses on convenience-store robberies, one of the most common forms of workplace violence, and finds that robbers are significantly more likely to injure employees who are present on the sales...
Developing life-saving medicines can take billions of dollars and decades of time, but University of Central Florida researchers are aiming to speed up this process with a new artificial intelligence-based drug screening process they've developed.
Efforts to improve the yields of staple cereal crops like maize and rice at scale in Africa remain seriously hampered by the effects of poor soil fertility. The lack of adequate information to base an effective fertilizer recommendation upon often results in inefficient nutrient use by crops and low crop yields. A root cause of poor crop response to applied nutrients is generalized fertilizer...
Engineered living materials promise to aid efforts in human health, energy and environmental remediation. Now they can be built big and customized with less effort.
Super-thin planet nurseries have a boosted chance of forming big planets, according to a study announced this week at the Europlanet Science Congress (EPSC) 2022 in Granada, Spain. An international team, led by Dr. Marion Villenave of NASA Jet Propulsion Laboratory (JPL), observed a remarkably thin disk of dust and gas around a young star, and found that its structure accelerated the process of...
Animals on the early branches of the tree of life, such as jellyfish and sea sponges, defy the usual conventions of aging. Some show abilities to regenerate damaged or missing tissues, halt or reverse aging, and in the case of at least one jellyfish species show a form of "immortality." A new study from researchers at the University of California, Davis, and Harvard Medical School takes a detailed...
According to satellite observations, Arctic sea ice reached its annual minimum extent on Sept. 18, 2022. The ice cover shrank to an area of 4.67 million square kilometers (1.80 million square miles) this year, roughly 1.55 million square kilometers (598,000 square miles) below the 1981-2010 average minimum of 6.22 million square kilometers (2.40 million square miles).
On Thursday, Sept. 29, at 2:36 a.m. PDT (5:36 a.m. EDT), NASA's Juno spacecraft will come within 222 miles (358 kilometers) of the surface of Jupiter's ice-covered moon, Europa. The solar-powered spacecraft is expected to obtain some of the highest-resolution images ever taken of portions of Europa's surface, as well as collect valuable data on the moon's interior, surface composition, and...
Discovery offers new support for the theory that life may have been seeded from outer spaceSpecks of dust that a Japanese space probe retrieved from an asteroid about 186 million miles (300m kilometres) from Earth have revealed a surprising component: a drop of water.The discovery offers new support for the theory that life on Earth may have been seeded from outer space.

"This lake wasn't here 50 years ago."
Gray and white flecks skitter erratically on a computer screen. A towering microscope looms over a landscape of electronic and optical equipment. Inside the microscope, high-energy, accelerated ions bombard a flake of platinum thinner than a hair on a mosquito's back. Meanwhile, a team of scientists studies the seemingly chaotic display, searching for clues to explain how and why materials degrade...
Researchers from Western University have developed a material that could eventually improve the way drugs are administered to patients, by allowing doctors to "see" exactly whether drugs are reaching the targets and working properly.
A dollop of margarine or spread can go a long way to livening up a slice of toast, a piping hot ear of corn or other food. But that enhanced flavor can also come with a side helping of worry over consuming saturated fats, which are used as solidifying agents in some margarines and spreads and give them their butter-like properties.
With a single sample of water or soil, researches can analyze the DNA of everything that is living in that environment. During her research, Ph.D. candidate Beilun Zhao discovered a way to analyze not only the kind of species, but also the age of the species in a water sample. The method showed its first success with the great pond snail and is the first step to a whole new world of environmental...
During the growing and harvest seasons, vegetable producers often begin their day before sunrise and finish as the last light is seeping into the horizon. These long days are normal but varied. Challenges such as pests, disease, climate change, and weather make each day and each growing season unique and unpredictable.
Tiny aerosol particles that are suspended in the air can absorb and scatter sunlight radiation and contribute to create clouds affecting climate, reduce the visibility over cities and affect air traffic, and lower air quality. Aerosols in large pollution plumes, called brown clouds, can be transported long distances by the wind and reach other continents from the originating one. The variable...
If global warming persists, blue lakes worldwide are at risk of turning green-brown, according to a new study which presents the first global inventory of lake color. Shifts in lake water color can indicate a loss of ecosystem health. The new research was published in Geophysical Research Letters.
Quantum computers and communication devices work by encoding information into individual or entangled photons, enabling data to be quantum securely transmitted and manipulated exponentially faster than is possible with conventional electronics. Now, quantum researchers at Stevens Institute of Technology have demonstrated a method for encoding vastly more information into a single photon, opening...
Sweet potato (Ipomoea batatas) production in the northern United States is limited due to the perceived barriers of a short growing season and relatively cool summer temperatures, yet recent studies have shown yield in northern regions can be greater than the national average when sweet potatoes are grown with plastic mulch. A study, now published in HortTechnology, was conducted in northwest...
Caladiums are ornamental aroids highly valued for their attractive foliage that rivals the display of many flowers. Aroid is a common name for a large species of plants in the Araceae family. This family of plants is also often called the Philodendron or Arum family. There are over 100 genera and 3,750 species of aroid plants, most of which are from the tropics.
Former Texas A&M University, College Station, material scientist Zhengdong Cheng pleaded guilty today to two federal charges of making false statements to NASA that hid his ties to two Chinese universities. Cheng also agreed to repay NASA $86,876, funds awarded for a microgravity experiment to be conducted on the International Space Station. Despite...
Groundwater—the water contained in porous and fractured rocks underground—is the largest freshwater source on Earth apart from the ice caps and glaciers. It feeds into rivers, lakes, and other surface water bodies and is essential for ecosystems. In addition, groundwater systems are an integral part of agricultural irrigation, especially in regions with scarce surface water resources.
