Plastic is a major threat to the environment. Of particular ecological risk is its manifestation as microplastics (<5 mm in size) in the agricultural environment. Scientists addressed this issue in a recent study, looking into the levels, shapes, and sizes of microplastics in Korean agricultural soils. They reported new insights on the agricultural sources of microplastics, contributing to a...
Researchers have shown that they can facilitate walking, relieve dizziness and improve quality of life in patients with BVH by surgically implanting a stimulator that electrically bypasses malfunctioning areas of the inner ear and partially restores the sensation of balance.
The songs of fin whales can be used for seismic imaging of the oceanic crust, providing scientists a novel alternative to conventional surveying.
Physicists take a step toward building a fault-tolerant quantum computer. They have realized a novel type of QEC where the quantum errors are spontaneously corrected.
Subconsciously, our bodies keep time for us through an ancient means - the circadian clock. A new article reviews how the clock controls various aspects of homeostasis, and how organs coordinate their function over the course of a day.
The songs of fin whales can be used for seismic imaging of the oceanic crust, providing scientists a novel alternative to conventional surveying, a new study published this week in Science shows.
As more male-dominated industries look for ways to hire women, new Cornell University research offers employers a simple solution—make your initial job candidate short list longer.
NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft has far exceeded its planned mission duration, revealing that the Moon holds surprises: ice deposits that could be used to support future lunar exploration, the coldest places in the solar system in permanently shadowed regions at the lunar poles, and that it is an active world that is shrinking, generating moonquakes and changing in front of...
A Southwest Research Institute scientist has updated Mars chronology models to find that terrains shaped by ancient water activity on the planet's surface may be hundreds of millions of years older than previously thought. This new chronology for Mars, based on the latest dynamical models for the formation and evolution of the solar system, is particularly significant as the days count down until...
Plastic, with its unabated global production, is a major and persistent contributor to environmental pollution. In fact, the accumulation of plastic debris in our environment is only expected to increase in the future. "Microplastics" (MP)—plastic debris
One thing that decades of social science research has made abundantly clear? Americans in urban areas live in neighborhoods deeply segregated by race—and they always have.
Women today represent two-thirds of all Canadian doctorates in archaeology, but only one-third of Canadian tenure-stream faculty. While men with Canadian Ph.D.s have done well in securing tenure-track jobs in Canada over the past 15 years, women have not, according to a new study from McGill University. The current COVID-19 pandemic is likely to exacerbate these existing inequalities.
New research shows that biodiversity is important not just at the traditional scale of short-term plot experiments—in which ecologists monitor the health of a single meadow, forest grove, or pond after manipulating its species counts—but when measured over decades and across regional landscapes as well. The findings can help guide conservation planning and enhance efforts to make human...
The Alberta government plans to create the largest contiguous protected boreal forest area in the world by expanding the Kitaskino Nuwenëné Wildland in the northeast part of the...
Researchers have mined and combined information from two databases to link pollen and key plant traits to generate confidence in the ability to reconstruct past ecosystem services.
Understanding how plants respond to stressful environmental conditions is crucial to developing effective strategies for protecting important agricultural crops from a changing climate. New research led by Carnegie's Zhiyong Wang, Shouling, Xu, and Yang Bi reveals an important process by which plants switch between amplified and dampened stress responses. Their work is published by Nature...
In a recent article in the Journal of Osteopathic Medicine, authors gathered previously published research to summarize current thinking on the feasibility and efficacy of using scent detection dogs to screen for the COVID-19 virus. The researchers report that sensitivity, specificity, and overall success rates reported by the canine scent detection studies are comparable or better than the...
Millions of tons of plastic waste find their way into the ocean every year. A team of researchers from the Institute for Advanced Sustainability Studies (IASS) in Potsdam has investigated the role of regional ocean governance in the fight against marine plastic pollution, highlighting why regional marine governance should be further strengthened as negotiations for a new global agreement continue.
The presence of high salt and nitrogen concentrations in high-tunnel soils may make it more challenging to rebuild a healthy soil microbiome following a soil-clearing event, according to microbial ecologists in Penn State's College of Agricultural Sciences.

Dengue virus is among growing number of mosquito-borne viruses that have adapted to spread in urban environments and are spreading with the increasing rate of urbanization. Now, researchers have identified tap water access in densely populated neighborhoods as a strong predictor of dengue risk in the city of Delhi.
A new genetic study of Native Hawaiians finds that people who have a greater proportion of Polynesian ancestry in their genomes face a higher risk of obesity, Type-2 diabetes and heart failure.
The majority of the population can produce neutralizing antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in severe cases of coronavirus disease 2019 (COVID-19), according to a new study. Moreover, the results support the use of combination antibody therapy to prevent and treat COVID-19.
A new computational analysis suggests that people under the age of 20 are about half as susceptible to COVID-19 infection as adults, and they are less likely to infect others.
Researchers discovered a single gene alteration that may help explain cognitive differences between modern humans and our predecessor, and used that information to develop Neanderthal-like brain organoids in the lab.
Scientists have challenged our current understanding of how galaxies form by unveiling pictures of a young galaxy in the early life of the Universe which appears surprisingly mature.
Researchers found people are more successful at identifying language associated with Republican speech than Democratic speech patterns.
In recent years, active, self-propelled particles have received growing interest amongst the scientific community. The 'swirlon' - a novel state of active matter - displayed a stunning behavior whereby instead of moving with acceleration, the quasi-particle groups moved with a constant velocity, proportional to the applied force and in the same direction of the force. This conduct seemingly...
A new largescale genetic analysis has found biological mechanisms that contribute to making people more susceptible to muscle weakness in later life, finding that diseases such as osteoarthritis and diabetes may play a large role in susceptibility.
Scientists were expecting to find an intermediate-mass black hole at the heart of the globular cluster NGC 6397, but instead they found evidence of a concentration of smaller black holes lurking there. New data from the NASA/ESA Hubble Space Telescope have led to the first measurement of the extent of a collection of black holes in a core-collapsed globular cluster.
Researchers developed a superconducting nanowire that could enable efficient, easy-to-make electronics. The advance could boost quantum computing, as well as magnetic sensors for applications in brain imaging and telescopes.
The golden-mantled ground squirrel is one of the most photographed animals in the Rocky Mountains. It's also joining many other species of rodents and shrews in Colorado that are making an ominous trek: They're climbing uphill to escape from climate change.
Fusing the neck's top two vertebrae can prevent repeat strokes in children with bow hunter syndrome, a rare condition that affects a handful of U.S. pediatric patients each year, researchers suggest in a recent study. The finding offers a new way to treat these children and protect them from potentially lifelong neurological consequences.
