Local rice varieties in Vietnam could be used to help breed improved crops with higher resilience to climate change, according to a new study published in Rice. Earlham Institute researchers are part of an international collaboration with genebanks and rice breeders in Vietnam -- championed by the International Rice Research Institute (IRRI) to help abolish world poverty and hunger -- are aiming to identify varieties that can survive an increasingly unpredictable climate.

Pesticides safeguard agricultural yields by controlling insects, fungi, and weeds. However, they also enter streams and damage the aquatic communities. In a nationwide monitoring program, scientists led by the Helmholtz Centre for Environmental Research have shown that the governmental thresholds for pesticides are too high and that these levels are still exceeded in over 80% of water bodies. The loss of biodiversity can only be halted if the environmental risk assessment of pesticides is revised.

New research led by the University of Kent has found that there is no link between bed sharing, infant-mother attachment, and infant behavioral outcomes.

The influx of warmer water masses from the North Atlantic into the European marginal seas plays a significant role in the marked decrease in sea-ice growth, especially in winter.

To counter the effects of climate change on drylands, a new study suggests that global access to water should be managed in a more integrated way.

Research led by the University of Kent and the STFC Rutherford Appleton Laboratory has resulted in the discovery of a new rare topological superconductor, LaPt3P. This discovery may be of huge importance to the future operations of quantum computers.

Research teams from Würzburg, Munich, Erlangen and the MDC in Berlin have identified, for the first time, where special receptors are located on heart muscle cells. Their findings open up new perspectives for developing therapies for chronic heart failure.

New research -- the evolution of complementary cognition -- proposes that in adapting to enormous environmental upheavals over hundreds of thousands of years, humans evolved to specialize in different but complementary forms of cognition, styles of 'thinking,' that work together as a complex adaptive system -- a kind of collective brain.

Scientists have identified how and why some Covid-19 patients can develop life-threatening clots, which could lead to targeted therapies that prevent this from happening.

A new antibody testing study examining samples originally collected through the National Institutes of Health's All of Us Research Program found evidence of SARS-CoV-2 infections in five states earlier than had initially been reported. These findings were published in the journal Clinical Infectious Diseases.

CNIO researchers have found out how PrimPol protein helps the cell to survive the damage caused by chemotherapy and plan to use this knowledge to enhance cancer treatments.

The University of Ottawa has been awarded four new Canada Research Chairs (CRC) that will strengthen its expertise in artificial intelligence, health and law, plus the renewal of two CRCs that will conduct leading-edge research in quantum communications and photonics.

A review of more than 9,000 US patients with severe COVID-19 infection showed less than 1% contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU Health Care.

Plants evolve specialized defense chemicals through the combined effects of genes, geography, demography and environmental conditions.

Canadian researchers have discovered that a bee thought to be rarest in North America, as the only representative of its genus, is no more than an unusual specimen of a widespread species. They have reclassified the mystery bee, collected in Nevada in the 1870s, as an aberrant specimen of the California digger-cuckoo bee, a cleptoparasitic bee, with females that lay eggs in the nests of digger bees.

In a new study led by Yale Cancer Center, researchers show the nucleoside transporter ENT2 may offer an unexpected path to circumventing the blood-brain barrier (BBB) and enabling targeted treatment of brain tumors with a cell-penetrating anti-DNA autoantibody. The study was published today online in the Journal of Clinical Investigation Insight.

A UCLA clinical trial has shown encouraging results in helping daily smokers who are also heavy drinkers quit smoking and reduce their alcohol intake.

Hippopotamus aren't the first thing that come to mind when considering epidemiology and disease ecology. And yet these amphibious megafauna offered UC Santa Barbara ecologist Keenan Stears a window into the progression of an anthrax outbreak that struck Ruaha National Park, Tanzania, in the dry season of 2017.

New research sheds light on how - and in what context - peacekeepers can contain the spread of violence in fragile post-conflict areas.

Changing your eating habits or altering your circadian clock can impact healthy fat tissue throughout your lifespan, according to a preclinical study published today in Nature by researchers with The University of Texas Health Science Center at Houston (UTHealth).

A new model that applies artificial intelligence to carbohydrates improves the understanding of the infection process and could help predict which viruses are likely to spread from animals to humans. This is reported in a recent study led by researchers at the University of Gothenburg.

Researchers at the University of Maryland School of Medicine (UMSOM) have developed two rapid diagnostic tests for COVID-19 that are nearly as accurate as the gold-standard test currently used in laboratories. Unlike the gold standard test, which extracts RNA and uses it to amplify the DNA of the virus, these new tests can detect the presence of the virus in as little as five minutes using different methods.

A "3D Culture System" developed by University of Southampton has closely replicated how cells infected with TB change in the human lung. Analytical evidence of these changes identified 7 key gene changes that cause damage in the lungs, from hundreds of thousands. A second trial showed that a common antibiotic, doxycycline, could help reverse these changes and speed up recovery.

According to a qualitative study published in JAMA Network Open adolescents expressed feelings of helplessness when exposed to secondhand racism online. Specifically, adolescents described helplessness stemming from the pervasiveness of racism in our society.

Humans can do lots of things that plants can't do. But plants have one major advantage over humans: They can make energy directly from the sun. That process of turning sunlight directly into usable energy - called photosynthesis - may soon be a feat humans are able to mimic to harness the sun's energy for clean, storable, efficient fuel. If so, it could open a whole new frontier of clean energy.
