Research shows SARS-CoV-2 promotes pain relief through the receptor neuropilin-1, which gives scientists a new target for non-opioid pain therapeutics and offers one possible explanation for the unrelenting spread of COVID-19.

Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth's climate during the last ice age.

Researchers have successfully overcome a limiting problem with stabilizing the best-performing formulation of metal-halide perovskite films, a key player in a range of applications, including solar cells.

Nanoparticles are valuable and useful in many products, but according to a new study, they can also damage our cells. Researchers are concerned about the effect of lifelong exposure to the human organism.

A mindfulness-based stress reduction course was found to benefit patients with chronic pain and depression, leading to significant improvement in participant perceptions of pain, mood and functional capacity, according to a new study. Most of the study respondents (89%) reported the program helped them find ways to better cope with their pain while 11% remained neutral.

A new database analysis of approximately 80,000 patients shows that people with Parkinson's disease (PD) have a 30 percent higher death rate from COVID-19 than people without the neurodegenerative condition.

New research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will enable improved thermal imaging, electronic warfare, radio communications and radar.

Experts working in the field of vaccine development tend to believe that an effective vaccine is not likely to be available for the general public before the fall of 2021. A new paper details the results of a recent survey of 28 experts working in vaccinology.

A new study shows that part of the stress response in people and animals involves increasing the levels of naturally circulating iodide in blood. The discovery demonstrates a biological mechanism that rapidly responds to severe physiologic stress and potentially serves to protect us from further damage due to life-threatening conditions.

Manatees don't live year-round in Texas, but these gentle sea cows are known to occasionally visit, swimming in for a 'summer vacation' and returning to warmer waters for the winter. New research has found fossil evidence for manatees along the Texas coast dating back to the most recent ice age. The discovery raises questions about whether manatees have been visiting for thousands of years, or if...

Researchers previously identified a host of genetic risk factors that help explain why some veterans are especially susceptible to the debilitating symptoms of post-traumatic stress disorder (PTSD).

Tissues and cells in the human body are subjected to a constant push and pull - strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by stretching different regions of DNA, researchers in China found in a new study.

The suggested apparatus produces controlled radiation with a narrow spectrum that can be tuned with high resolution, at a relatively low energy investment. The findings are likely to lead to breakthroughs in a variety of fields, including the analysis of chemicals and biological materials, medical imaging, X-ray equipment for security screening, and other uses of accurate X-ray sources

A class of compounds used for malaria treatment also kill the intestinal parasite Cryptosporidium, a leading cause of diarrheal disease and death in children that has no cure, a multi-institution collaboration of researchers found in a new study.

Whether flu or coronavirus, it can take several days for the body to ramp up an effective response to a viral infection. New research describes how different cells in the immune system work together, communicate, and - in the case of cells called neutrophils - bring about their own death to help fight off infections. The findings could have important implications for the development of vaccines...

Researchers report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the understanding of sustainable groundwater in California's San Joaquin Valley.

In September 2015, the US National Institutes of Health placed a funding moratorium on research that involves introducing human pluripotent stem cells into animal embryos. To assess attitudes on human-animal chimeric embryo research, investigators conducted a survey among 430 Americans. The results of the survey found that 82% of people are supportive of at least some parts of this research.

Researchers have developed electronic blood vessels that can be actively tuned to address subtle changes in the body after implantation. The blood vessels -- made of a metal-polymer conductor membrane that's flexible and biodegradable -- mimic natural blood vessels, were conductive in in vitro experiments, and were able to effectively replace key arteries in rabbits.

Through the use of two advanced audio recording technologies, researchers have found that blue whales switch from nighttime to daytime singing when they are starting to migrate.

Naturally formed balancing boulders could be used to help scientists to forecast large earthquakes more precisely.

Researchers have revealed our most ancient ancestors were ecologically diverse, despite lacking jaws and paired fins.

Repeating a study conducted in 1914, scientists have shown that species may be able to evolve and adapt to rapid climate change.

Today, the American Gastroenterological Association (AGA) released the first results from the largest real-world study on the safety and effectiveness of FMT. The registry reported that FMT led to a cure of Clostridioides difficile (C. difficile) infection in 90% of patients across 20 North American FMT practice sites. Few serious side effects were reported.

Astrophysicists put general relativity to a new test with black hole images.
