An oral antiviral drug that targets a key part of the respiratory syncytial virus (RSV) polymerase and inhibits the synthesis of viral genetic material has been identified, a finding that could provide an effective treatment against RSV disease.

Researchers describe how the microbiomes of people and the homes they live in interact and change each other.

While lower vertebrates can repair their adult hearts after a heart attack, mammals -- including humans -- cannot. The ability to regenerate dead muscle tissue in mammalian hearts disappears just a few days after birth because the heart muscle cells, called cardiomyocytes, exit the cell cycle. In 2020, researchers reported that surgery to remove the left ventricle apex of the heart of pigs, one...

For decades, field-effect transistors enabled by silicon-based semiconductors have powered the electronics revolution. But in recent years, manufacturers have come up against hard physical limits to further size reductions and efficiency gains of silicon chips. That has scientists and engineers looking for alternatives to conventional metal-oxide semiconductor (CMOS) transistors.

A research group has explored the potential production of micro-scale organic electronics for use in bioelectronics via multiphoton 3-D printers.

Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer scale. A research team has now investigated a super-resolution imaging technique that involves...

Along with high blood pressure, diabetes, and smoking, environmental factors such as air pollution are highly predictive of people's chances of dying, especially from heart attack and stroke, a new study shows.

In the largest epidemiologic study of arsenic and birth outcomes to date, researchers estimated arsenic levels in U.S. private well water sources by county and compared estimates to documented birth outcomes. They found an association between estimated groundwater arsenic concentration and risk of low birth weight.

Most research on immunity to the SARS-CoV-2 virus and COVID-19 vaccine development has focused on antibody responses to the spike protein and other viral surface proteins. But antibodies that recognize the virus's internal proteins could also be important for immunity and disease outcomes, according to a new study.

People who received at least one influenza vaccine were 40% less likely than their non-vaccinated peers to develop Alzheimer's disease over the course of four years, according to a new study.

Severe 'brain bleeds' experienced by some babies in the first year following their birth can lead to long-term sight problems, researchers have found as part of a ten-year follow-up study.

Researchers have made a new discovery on how light behaves in complex media, media that tends to distort light significantly. They demonstrated that 'distortion' is a matter of perspective, outlining a simple rule that applies to all light and a vast array of media, including underwater, optical fiber, transmission in the atmosphere and even through living biological samples. Their novel quantum...

A new study provides additional evidence that COVID-19 vaccination during pregnancy helps protect babies younger than 6 months from being hospitalized due to COVID-19.

Fine-tuning the thermal conductivity of amorphous silicon used in technologies such as solar cells and image sensors should become much easier thanks to the computational topology and machine-learning-assisted discovery of the relationship between nano-scale structures and physical properties.

Communication networks need nodes at which information is processed or rerouted. Physicists have now developed a network node for quantum communication networks that can store single photons in a vapor cell and pass them on later.

Researchers have demonstrated an improved version of impedance cytometry that uses four frequencies of applied AC voltage to measure the size and shape of individual microorganisms. By ensuring that the voltages penetrated the cell membrane, this approach can more accurately monitor biological processes.

Automation in disease diagnosis is reliant on deep learning models that can accurately and efficiently identify measurements of tumors, tissue volume, or other sorts of abnormalities. Now, researchers have unveiled a new, resource-light model capable of identifying many common eye diseases.

The neural and cognitive complexity of the octopus could originate from a molecular analogy with the human brain, according to a new study. The research shows that the same 'jumping genes' are active both in the human brain and in the brain of two species, Octopus vulgaris, the common octopus, and Octopus bimaculoides, the Californian octopus.

Older adults with untreated sight conditions may be at increased risk of dementia, according to a new systematic review and meta-analysis of 16 studies involving 76,373 participants.

Temperature changes have negatively impacted most species of bumble bees over the past 120 years, according to new new research. The researchers note that changes in temperature had more of a negative impact than other factors -- such as precipitation or floral resources.

The female hormone estradiol was found to suppress psoriasis in mice by regulating neutrophil and macrophage cells. The conditional knockout mice without the natural ovarian hormones estradiol showed symptoms of severe skin inflammation.

Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical analysis. It works using a technique called Raman spectroscopy, where laser light aimed at the sensor is changed slightly depending on whatever chemicals are present on the...

Researchers say people with developmental dyslexia have specific strengths relating to exploring the unknown that have contributed to the successful adaptation and survival of our species.

Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration -- that is, increased variability in movements -- is important when learning a new task. These results may lead to improved motor rehabilitation in patients after injury or disease.
