ETH researchers examined chemicals in plastics worldwide. They found an unexpectedly high number of substances of potential concern intentionally used in everyday plastic products. A lack of transparency limits management of these chemicals.

While scientists have known that PTSD and migraine often co-occur, no-one had studied this link, before now. A new study by the open access publisher Frontiers on identical twins investigates the genetic basis for both migraine and PTSD. It reveals epigenetic risk factors that are shared by PTSD and migraine, suggesting that similar environmental risk factors are at play in both conditions. The findings could help researchers to develop new treatments.

Researchers have shown why people with mental health disorders, including anorexia and panic disorders, experience physical signals differently.

Rutgers scientists have used a diagnostic technique for the first time in the opioid addiction field that they believe has the potential to determine which opioid-addicted patients are more likely to relapse

Protected Satellite Communications constitute one of the key research topics in modern communications and exhibit specific characteristics such as security, intelligence, anti-jamming, and nuclear disaster survivability. In the modern intelligent age, many intelligent-related technologies are introduced into SatCom systems to provide more secure and efficient communication services. In this paper, a comprehensive overview of the protected SatCom systems is presented. Science China Information Sciences reported this paper in the sixth issue of 2021.

Researchers from the National University of Singapore and University of the Ryukyus have recently identified and described a new genus and species of xanthid crab found in Okinawa Island, Ryukyu Islands, Japan. Named Mabui calculus, it is the first among the 7,800 species of known crabs to have strongly asymmetrical male and female reproductive structures.

A novel way of synthesizing an essential powder is key to raising the efficiency of perovskite solar cells, say researchers at the Okinawa Institute of Science and Technology Graduate University.

High-resolution satellite imagery data unveiled a global correlation between urban green space and happiness in 60 countries.

A recent study revealed that as a city becomes more economically developed, its citizens' happiness becomes more directly related to the area of urban green space.

Holding onto everyday items as keepsakes when a loved one dies was as commonplace in prehistory as it is today, a new study suggests.

A smartphone-based eye screening and referral system used in the community has been shown to almost triple the number of people with eye problems attending primary care, as well as increasing appropriate uptake of hospital services, compared to the standard approach. The new findings come from research carried out in Kenya, published in The Lancet Digital Health.

Combining atomic-scale sample analysis and models simulating likely conditions in the nascent solar system, the study revealed clues about the origin of crystals that formed more than 4.5 billion years ago. The findings provide insights into the fundamental processes underlying the formation of planetary systems, many of which are still shrouded in mystery

The largest, most extensive global study of background rates for adverse events of special interest identifies important differences by age, sex, and database that will inform COVID vaccine safety monitoring.

Researchers at the University of Pittsburgh Swanson School of Engineering used a Computational Fluid Dynamics model to find ways to decrease cost and increase usage of cooler surfaces. The paper, published in the journal Nature Communications, examined the possibility of applying cooler surfaces to just half the surfaces in a city.

A new study considered the extent to which police misconduct is likely to be reduced by removing police officers identified early in their careers as being at risk for misconduct. The study concluded that replacing the top 10 percent of police identified as being the most likely to generate use-of-force complaints with officers who have not or are less likely to do so would reduce use-of-force complaints by just 6 percent over a 10 year period.

An increase in women running for office in recent years has not been a "flash in the pan." UC Davis researchers expect women to continue to run for office, and do so repeatedly whether they win or lose.

New analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice. Published in the PNAS, the study -- which includes contributions by Baylor University planetary physicist Peter James, Ph.D. -- found that the movement of these blocks could indicate that Venus is still geologically active and give scientists insight into both exoplanet tectonics and the earliest tectonic activity on Earth.

A new position statement from the American Academy of Sleep Medicine emphasizes that sleep is a biological necessity, and insufficient sleep and untreated sleep disorders are detrimental for health, well-being, and public safety.

In two separate articles in the Annals of Neurology, clinicians in India and England report cases of a rare neurological disorder called Guillain-Barre? syndrome after individuals were vaccinated against COVID-19.

The initial chemotherapy of aggressive childhood nerve tumors, so-called high-risk neuroblastomas, is crucial for ultimate survival. It has now been shown that the chemotherapy regimen used by the European Neuroblastoma Study Group is equally efficacious but better tolerated than a highly effective regimen from the US. This was the conclusion of an international trial coordinated by St. Anna Children's Cancer Research Institute. The study was published in the prestigious Journal of Clinical Oncology.
