Reducing pesticide pollution and the intensity of harvesting can increase crop yield and contribute to climate change mitigation

Science Daily - 08/02/2023
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.

This loofah-inspired, sun-driven gel could purify all the water you'll need in a day

Science Daily - 08/02/2023
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.

Keeping SARS-CoV-2 closed for business with small molecules

Science Daily - 08/02/2023
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.

Discovery of T-cells that protect against deadly pneumococcal disease

Science Daily - 08/02/2023
A new study reveals how resistance to bacteraemic pneumonia is provided by a unique subset of lung T regulatory cells.

Spanish lagoon used to better understand wet-to-dry transition of Mars

Science Daily - 08/02/2023
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.

What makes people care about the environment?

Science Daily - 08/02/2023
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.

Severe weather straining electrical grids: New research mitigates demand surges, increasing grid reliability and reducing costs

Science Daily - 08/02/2023
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.

Wear and forget: An ultrasoft material for on-skin health devices

Science Daily - 08/02/2023
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' attention to 'motherese' speech may be used to diagnose autism

Science Daily - 08/02/2023
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.

Telomeres, mitochondria, and inflammation oh my! Three hallmarks of aging work together to prevent cancer

Science Daily - 08/02/2023
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.

A new ring system discovered in our Solar System

Science Daily - 08/02/2023
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.

Footprints of galactic immigration uncovered in Andromeda galaxy

Science Daily - 08/02/2023
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 same Arctic calving grounds for 3,000 years

Science Daily - 08/02/2023
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.

Killer whale moms forgo future offspring for benefit of full-grown sons

Science Daily - 08/02/2023
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.

Global wetlands losses overestimated despite high losses in many regions

Science Daily - 08/02/2023
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.

New research suggests drought accelerated empire collapse

Science Daily - 08/02/2023
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.
