Researchers have found that carbon sequestration and plant resilience as well as forage pasture yield can be increased through key adjustments in agricultural management. The results provide a roadmap for reducing pesticide loads in soils and the first steps towards increasing climate change mitigation while improving crop yield in grasslands.
Access to clean water is being strained as the human population increases and contamination impacts freshwater sources. Devices currently in development that clean up dirty water using sunlight can only produce up to a few gallons of water each day. But now, researchers in ACS Central Science report how loofah sponges inspired a sunlight-powered porous hydrogel that could potentially purify enough water to satisfy someone's daily needs -- even when it's cloudy.
The infamous spike proteins on the surface of SARS-CoV-2 help it bind to and enter human cells. Because of their important role in spreading infection, these spike proteins are one of the main targets for COVID-19 vaccines and treatments. But those remedies gradually lose effectiveness when certain segments of the spike proteins mutate. Now, researchers report that they have discovered small molecules that successfully target other segments that mutate less.
A new study reveals how resistance to bacteraemic pneumonia is provided by a unique subset of lung T regulatory cells.
In the ongoing search for signs of life on Mars, a new study proposes focusing on 'time-resolved analogs' -- dynamic and similar Earth environments where changes can be analyzed over many years.
A new study analyzes the factors that drive environmental concern among Europeans in an effort to understand how we can bolster popular support for combating climate change.
Concerns are mounting among policymakers and utility companies amid the impact of severe weather on the nation's electrical grids. In recent months, electrical grids in Texas have been tested to the point of near failure. So it seems like perfect timing that new research identifies a new method that provides the best way to utilize 'direct load control contracts' to mitigate electricity demand surges, increase grid reliability and reduce electricity cost. All of this right down to the individual household.
With cancer, diabetes and heart disease among the leading causes of disability and death in the United States, imagine a long-term, in-home monitoring solution that could detect these chronic diseases early and lead to timely interventions. Now, researchers may have a solution. They have created an ultrasoft 'skin-like' material -- that's both breathable and stretchable -- for use in the development of an on-skin, wearable bioelectronic device capable of simultaneously tracking multiple vital signs such as blood pressure, electrical heart activity and skin hydration.
Toddlers' level of attention to 'motherese' speech can be used as a biomarker for autism spectrum disorder (ASD), according to new research. To measure it, scientists developed a new eye-tracking test, which can accurately identify toddlers with a subtype of ASD.
Scientists have discovered that when telomeres become very short, they communicate with mitochondria, the cell's powerhouses. This communication triggers a complex set of signaling pathways and initiates an inflammatory response that destroys cells that could otherwise become cancerous. The findings could lead to new ways of preventing and treating cancer as well as designing better interventions to offset the harmful consequences of aging.
Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed.
Astronomers have uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that of the Milky Way.
Caribou have been using the same Arctic calving grounds for more than 3,000 years. Female caribou shed their antlers within days of giving birth, leaving behind a record of their annual travels across Alaska and Canada's Yukon that persists on the cold tundra for hundreds or even thousands of years. Researchers recovered antlers that have sat undisturbed on the arctic tundra since the Bronze Age.
It's not unusual for parents and especially mothers to sacrifice their own future success for the sake of their offspring. Now a new study shows that killer whale mothers take this to a surprising extreme. They sacrifice their own reproductive success to care for their sons, even after those sons are full-fledged adults.
New analysis shows the U.S. has accounted for more wetland conversion and degradation than any other country. Its findings help better explain the causes and impacts of such losses and inform protection and restoration of wetlands.
The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, scientists have used tree ring and isotope records to pinpoint a more likely culprit: three straight years of severe drought.
There are gaps along the Himalayan axis where the historical release of geological tension doesn’t fully account for the strain that has built up.
An oncologist explains why interest in the new technology goes beyond providing a new lease of life to people with leukaemias and lymphomas.
How do you build complex structures for housing cells using a material as soft as jelly? Researchers have the answer with a new 3D-printing ink.
