Researchers have created the first CRISPR-Cas9-based gene drive designed for plants. The new technology, which allows scientists to cut and copy key genetic elements, helps scientists breed plants that defend against crop diseases and withstand the impacts of climate change.

Older men with erectile dysfunction are having more sex than ever before, Pitt study finds.

A new University of Liverpool study could help scientists mitigate the future spread of zoonotic and livestock diseases caused by existing viruses.Researchers have used a form or artificial intelligence (AI) called machine-learning to predict more than 20,000 unknown associations between known viruses and susceptible mammalian species. The findings, which are published in Nature Communications, could be used to help target disease surveillance programmes.

Researchers at the National Institute of Standards and Technology (NIST) and Wavsens LLC have developed a method for using radio signals to create real-time images and videos of hidden and moving objects, which could help firefighters find escape routes or victims inside buildings filled with fire and smoke. The technique could also help track hypersonic objects such as missiles and space debris.

Multisystem Inflammatory Syndrome in Children (MIS-C) significantly affected more Black and Latino children than white children, with Black children at the highest risk, according to a new observational study of 124 pediatric patients treated at Children's National Hospital in Washington, D.C. Researchers also found cardiac complications, including systolic myocardial dysfunction and valvular regurgitation, were more common in MIS-C patients who were critically ill.

Researchers have built and validated an online calculator that empowers individuals 55 and over to better understand the health of their brain and how they can reduce their risk of being diagnosed with dementia in the next five years.

Like two superheroes finally joining forces, Sandia's Z machine -- generator of the world's most powerful electrical pulses -- and Lawrence Livermore's National Ignition Facility -- the planet's most energetic laser source -- have detailed gold and platinum responses to pressures so extreme that their atomic structures momentarily distorted like images in a fun-house mirror.Until now there has been no way to accurately calibrate these pressures , the first step to controlling them.

POSTECH joint research team confirms the suppression and therapeutic effects of specific structural polysaccharide found in yeast for inflammatory diseases in animal models.

New research has discovered that common artificial sweeteners can cause previously healthy gut bacteria to become diseased and invade the gut wall, potentially leading to serious health issues. The study, published in the International Journal of Molecular Sciences, is the first to show the pathogenic effects of some of the most widely used artificial sweeteners - saccharin, sucralose, and aspartame - on two types of gut bacteria, E. coli (Escherichia coli) and E. faecalis (Enterococcus faecalis).

An editorial published by The BMJ today raises important concerns about the health and wellbeing of the NHS workforce after a parliamentary report found "burnout is a widespread reality in today's NHS."

Over the last decade, severe outbreaks of bacterial canker have caused huge economic losses for kiwi growers. Bacterial canker is caused by the bacterial pathogen Pseudomonas syringae pv. actinidiae (Psa) and more recent outbreaks have been particularly devastating due to the emergence of a new, extremely aggressive biovar called Psa3. Due to its recent introduction, the molecular basis of Psa3's virulence is unknown, making it difficult to develop mitigation strategies.

The project is the only comprehensive, large-scale Alzheimer's research study into the three largest ethnic groups in the U.S. - Non-Hispanic whites, Mexican Americans and African Americans.

The virus that causes COVID-19 normally gets inside cells by attaching to a protein called ACE2. Researchers at Washington University School of Medicine in St. Louis have found that a single mutation confers the ability to enter cells through another route, which may threaten the effectiveness of COVID-19 vaccines and therapeutics designed to block the standard route of entry.

A sharp-edged aperture developed by researchers from Jinan University is a promising solution for eliminating side lobes from superoscillatory waves.

Rice University engineers use graphene quantum dots to trap transition metals for high atom loading in single atom catalysis.

A new Cornell University study of Aedes aegypti mosquitoes investigates how a mating cue called "harmonic convergence" might affect immunity against parasites, bacteria and dengue virus in offspring, which has important implications for trade-offs male mosquitoes make between investing energy towards immunity or investing it on traits that impact mating and fitness.

Designing a recycling strategy for a new, forthcoming generation of photovoltaic solar cells - made from metal halide perovskites, a family of crystalline materials with structures like the natural mineral calcium titanate - will add a stronger dose of environmental friendliness to a green industry, according to new research published in Nature Sustainability.

Ozone levels in the earth's troposphere (the lowest level of our atmosphere) can now be forecasted with accuracy up to two weeks in advance, a remarkable improvement over current systems that can accurately predict ozone levels only three days ahead. The new artificial intelligence system developed in the University of Houston's Air Quality Forecasting and Modeling Lab could lead to improved ways to control high ozone problems and even contribute to solutions for climate change issues.

A new study could lead to improved decision making in assigning treatments for children with the aggressive cancer rhabdomyosarcoma after revealing key genetic changes underlying development of the disease.

In children with rhabdomyosarcoma, or RMS, a rare cancer that affects the muscles and other soft tissues, the presence of mutations in several genes, including TP53, MYOD1, and CDKN2A, appear to be associated with a more aggressive form of the disease and a poorer chance of survival. This finding is from the largest-ever international study on RMS, led by scientists at the National Cancer Institute’s (NCI) Center for Cancer Research, part of the National Institutes of Health.
