Researchers describe the underlying signaling pathway that results in pulmonary arterial hypertension and a novel monoclonal antibody therapy that blocks the abnormal blood vessel formation characterizing the disease.

Labeling the credibility of information sources does not shift the consumption of news away from low-quality sources or reduce belief in widely circulated inaccurate claims among average internet users, but providing an indicator of sources' quality may improve the news diet quality of the heaviest consumers of misinformation.

Using future projections from the latest generation of Earth System Models, a recent study found that most of the world's ocean is steadily losing its year-to-year memory under global warming.

Insect diversity is declining in Bavaria. Land use is a major driver, but the impact of climate change is still unknown. A study has now investigated in more detail how both factors interact in driving insect diversity and what can be done to conserve it.

The health care industry accounts for about 8.5% of all greenhouse gas emissions in the United States, and surgery is one of hospitals' biggest culprits in this space. Two surgeons-in-training give some solutions to combat this problem.

Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists discovered five subpopulations of retinal pigment epithelium (RPE) -- a layer of tissue that nourishes and supports the retina's light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell...

A colorful candy nonpareil coating gives pills a unique pattern that can be stored by the manufacturer in a database. Consumers could upload a smartphone photograph of a pill and if its CandyCode matches one in the database, the consumer could be confident that the pill is genuine. If not, it is potentially fraudulent.

Every species, from bacteria to humans, is capable of regeneration. Regeneration is mediated by the molecular processes that regulate gene expression to control tissue renewal, restoration and growth.

Historic graffiti of ships carved in an African fort were drawn by soldiers on guard duty watching the sea, experts believe.

A coaching program aimed at decreasing burnout among female resident physicians significantly reduced emotional exhaustion and imposter syndrome while increasing self-compassion over a six month period.

Researchers found that inversions in the human genome form more commonly than previously thought, which impacts our understanding of certain genetic diseases.

A team has developed a new family of two-dimensional materials that researchers say has great potential for many applications such as batteries and supercapacitors, catalysis, sensors and electronics.

Southeast Asia's most productive agricultural region and home to 17 million people could be mostly underwater within a lifetime. Saving the Mekong River Delta requires urgent, concerted action among countries in the region to lessen the impact of upstream dams and better manage water and sediments within the delta, according to an international team of researchers who outline solutions to the...

A theoretical study shows that long-range entanglement can indeed survive at temperatures above absolute zero, if the correct conditions are met.

To provide a convenient tool for the early detection of injuries, researchers have developed a portable MRI device for diagnosing cartilage damage in the wrist. Using this device, the researchers imaged the wrists of tennis players at a tennis school. Several athletes were found to have cartilage damage without any other symptoms of an injury. Thus, this device provides a convenient early...

Farmlands across Europe are potentially the biggest global reservoir of microplastics due to the high concentrations found in fertilizers derived from sewage sludge, new research has shown.

Researchers have analyzed cutting-edge device structures of quantum computers to demonstrate that some of them are indeed operating dangerously close to a threshold of chaotic meltdown. The challenge is to walk a thin line between too high, but also too low disorder to safeguard device operation.

Study finds that patients of orthopaedic and urologic procedures were more likely to dispose of their extra opioid tablets when they received kits in the mail to do so.

An international team of researchers have developed advanced computer models, or 'digital twins', of diseases, with the goal of improving diagnosis and treatment. They used one such model to identify the most important disease protein in hay fever. The study underlines the complexity of disease and the necessity of using the right treatment at the right time.

It's often said that a little stress can be good for you. Now scientists have shown that the same may be true for cells, uncovering a newly-discovered mechanism that might help prevent the build-up of tangles of proteins commonly seen in dementia. Scientists have identified a new mechanism that appears to reverse the build-up of aggregates, not by eliminating them completely, but rather by...

Results of a new study which asked participants to take a week-long break from TikTok, Instagram, Twitter and Facebook find positive effects for wellbeing, depression and anxiety.

Researchers have developed a single-material, single-stimuli microstructure that can outmaneuver even living cilia. These programmable, micron-scale structures could be used for a range of applications, including soft robotics, biocompatible medical devices, and even dynamic information encryption.

Native species in California's estuaries are expected to experience greater declines as invasive species interact with climate change, according to a new study.

A study suggests that women who get recurrent urinary tract infections (UTIs) may be caught in a vicious cycle in which antibiotics given to eradicate one infection predispose them to develop another.
