Over 80 percent of COVID-19 patients have vitamin D deficiency, study finds

2 hours 19 min ago
Over 80 percent of 200 COVID-19 patients in a hospital in Spain have vitamin D deficiency, according to a new study.

'White matter lesion' mapping tool identifies early signs of dementia

3 hours 4 min ago
A new tool for analyzing tissue damage seen on MRI brain scans can detect with more than 70% accuracy early signs of cognitive decline, new research shows.

Healthcare as a climate solution

17 hours 1 min ago
Although the link may not be obvious, healthcare and climate change -- two issues that pose major challenges around the world -- are in fact more connected than society may realize. So say researchers, who are increasingly proving this to be true.

Floating gardens: More than just a pretty place

17 hours 1 min ago
Floating gardens sound so idyllic. Now, a study proves that they are more than just a pretty place. The study demonstrates that such constructed gardens can have a measurable, positive impact on water quality.

DrugCell: New experimental AI platform matches tumor to best drug combo

18 hours 52 min ago
Researchers use experimental artificial intelligence system called DrugCell to predict the best approach to treating cancer.

Sea-level rise global observing system proposed

18 hours 57 min ago
A researcher proposes a new approach to monitoring global sea-level rise. Using the existing NOAA Global Drifter Program array of roughly 1,200 buoys that drift freely with ocean currents, he suggests adding additional instruments to record their height, or the 'level of the sea' they ride on, to collect long-term data on the average sea levels across the world's oceans.

New insights into a potential target for autoimmune disease

18 hours 57 min ago
With insights into a molecular pathway that regulates the activity of Tregs, a type of T cell involved in immunosuppression, new research opens up possibly new avenues for treating inflammatory and autoimmune diseases.

New map of the immune landscape in pancreatic cancer could guide immunotherapy

18 hours 57 min ago
A new analysis highlights the diversity of immune response in pancreatic cancer, and points toward the need for treatments tailored to individual patients.

Material properties for longer-lasting, more efficient solar cells

18 hours 57 min ago
Researchers are helping to understand the fundamental processes in a material known as perovskites, work that could lead to more efficient solar cells that also do a better job of resisting degradation.

On-surface synthesis of graphene nanoribbons could advance quantum devices

18 hours 57 min ago
Scientists have synthesized graphene nanoribbons -- ultrathin strips of carbon atoms -- on a titanium dioxide surface using an atomically precise method that removes a barrier for custom-designed carbon nanostructures required for quantum information sciences.

Wildlife flock to backyards for food from people

A new study helps explain why some animals are sometimes more often found in suburban areas than wild ones.

Risk score predicts prognosis of outpatients with COVID-19

18 hours 57 min ago
A new artificial intelligence-based score considers multiple factors to predict the prognosis of individual patients with COVID-19 seen at urgent care clinics or emergency departments. The tool can be used to rapidly and automatically determine which patients are most likely to develop complications and need to be hospitalized.

Greenhouse effect of clouds instrumental in origin of tropical storms

20 hours 1 min ago
With the tropical storm season in the Atlantic Ocean underway and already well into the Greek alphabet for naming, better storm track prediction has allowed timely evacuations and preparations. However, the formation and intensification of these storms remains challenging to predict, according to an international team of researchers who are studying the origin of tropical cyclones.

Why bats excel as viral reservoirs without getting sick

20 hours 1 min ago
A new study confirms bats adopt multiple strategies to reduce pro-inflammatory responses, thus mitigating potential immune-mediated tissue damage and disease. Findings provide important insights for medical research on human diseases.

Inks containing lead were likely used as drier on ancient Egyptian papyri

20 hours 1 min ago
Analyzing 12 ancient Egyptian papyri fragments with X-ray microscopy, researchers were surprised to find previously unknown lead compounds in both red and black inks and suggest they were used for their drying properties rather than as a pigment. A similar lead-based 'drying technique' has also been documented in 15th century European painting, and the discovery of it in Egyptian papyri calls for a reassessment of ancient lead-based pigments.

Summer road trip finds small streams have big impacts on Great Lakes

20 hours 2 min ago
While decades of monitoring and regulatory efforts have paid little attention to Lake Michigan's tiny tributaries, new research shows that they play an outsized role in feeding algae blooms and impacting coastal waters.

Localized vaccination surveillance could help prevent measles outbreaks

20 hours 2 min ago
Access to more localized data on childhood vaccination coverage, such as at the school or neighborhood levels, could help better predict and prevent measles outbreaks in the United States, according to a new study.

New COVID-19 related genes -- helpful and harmful -- found in massive screen

20 hours 2 min ago
Researchers screened hundreds of millions of cells exposed to the COVID-19 and MERS viruses and identified dozens of genes that both enable the viruses to replicate in cells and also those that seem to slam the door on the virus. The pro-viral and anti-viral role of these genes will help guide scientists in development of new therapies to combat COVID-19, the researchers say.

Most dentists have experienced aggression from patients

Roughly half of US dentists experienced verbal or reputational aggression by patients in the past year, and nearly one in four endured physical aggression, according to a new study.

Microplastics in groundwater (and our drinking water) present unknown risk

20 hours 2 min ago
Microplastics (plastics <5mm) and their negative health impacts have been studied in oceans, rivers, and even soils, and scientists are beginning to grapple with the myriad human health impacts their presence might have. One understudied, but critical, link in the cycle is groundwater, which is often a source of drinking water.
