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.

Contradicting theories of primatologists, a study led by Brazilian scientists shows that in a habitat with high hunting pressure, the risk of predation influences the habits of these monkeys more than the availability of food. They spend less time in areas they perceive as 'more dangerous' even if plant biomass and invertebrates are more abundant there.

Scientists at Gladstone Institutes have created an organoid--a three-dimensional cluster of cells grown in the lab--that mimics the earliest developmental steps of the nervous system in embryos. The organoid is the first to show how human spinal cord cells become oriented in an embryo, and could shed light on how environmental exposures or toxins can make this process go awry, causing early miscarriages and birth defects.

The American Geriatrics Society (AGS) has published an updated version of the AGS Minimum Geriatrics Competencies for Graduating Medical Students, which were created to ensure that medical school graduates across the US are prepared to provide high-quality care for us all as we age. A workgroup of American Geriatrics Society leaders updated the original competencies using a modified Delphi method to reach a group consensus based on expert and stakeholder input and a literature review.

Field trials investigating healthy compounds in agronomically important brassica crops have underlined the "immense potential" of gene editing technology, say researchers.

Rice University bioengineers collaborated on a six-year study that systematically analyzed how the surface architecture of silicone breast implants influences adverse side effects.

In recent years, many juvenile courts have adopted in-home detention with electronic monitoring tethers as an alternative to institutional incarceration. A new study examined whether this approach reduces recidivism among girls involved in the juvenile justice system. The study found that tethers failed to reduce reoffending among the girls; in fact, they may be harmful because in-home detention limits girls' access to treatment programs.

'We invented an artificial nose based on unique carbon nanoparticles ('carbon dots') capable of sensing gas molecules and detecting bacteria through the volatile metabolites the emit into the air,' says lead researcher Professor Raz Jelinek, BGU vice president for Research & Development, member of the BGU Department of Chemistry and the Ilse Katz Institute for Nanoscale Science and Technology, and the incumbent of the Carole and Barry Kaye Chair in Applied Science.

New research from the Hypothetical Materials Lab at the University of Pittsburgh Swanson School of Engineering develops a framework to understand the choices an electronic waste recycler has to make and the role that digital fraud prevention could have in preventing dishonest recycling practices.

An interdisciplinary team of researchers has succeeded in depositing nitrogen-containing organic molecules as a highly ordered layer on silicon. This opens up new perspectives for the development of more powerful semiconductor materials, which can be used, for example, in computers, photovoltaics or sensor technology.

Research from Imperial College London has found that lead from leaded petrol persists in London's air despite its ban in 1999.

Wetter conditions in Sub-Saharan and North Africa at certain times of year can result in hundreds of times more Painted Lady butterflies making the 14,000km round trip to Europe. Findings improve understanding of how insects move to other countries, including pests that destroy crops and disease-carrying species like mosquitoes.

Team used Argonne's GREET model to simulate changes, predict outcomes.

New research finds women who lose local or state elections are just as likely to run for office again as men, suggesting the recent surge in women candidates may have a long-term impact on women's political representation. Political scientists Rachel Bernhard of UC-Davis and Justin de Benedictis-Kessner of Harvard Kennedy School found no evidence of a gender gap in candidates' responses to losing a race. Their study was published today in the Proceedings of the National Academy of Sciences.

USC Stem Cell has identified a type of injured cell that might contribute to the transition from an acute kidney injury to chronic kidney disease. When an injury caused proximal tubule cells (PTCs) to die, surviving ones multiplied to repair the injury. But after function was restored, some PTCs which failed to repair normally appeared at the injury site. These damaged cells showed activity implicated in processes associated with progression to chronic disease.
