Researchers reveal a mechanism by which prostate cancer cells become resistant through molecular modification of the androgen receptor protein and identify a potential treatment approach that could overcome this resistance.

New research uses multiple polarization channels to carry out parallel processing -- enhancing computing density by several orders over conventional electronic chips.

Dog-assisted interventions can lead to significantly lower stress in children both with and without special needs, according to a new study using salivary cortisol levels.

A new study of intermediate school students in urban California and New York shows promise for underachievers. Researchers found that early intervention with teachers, training students that achievement is malleable and achievable, caused struggling students to flourish and improve their grades.

Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). Now we can see the nebula in a new light, with wispy gas clouds that provide insight into how massive stars shape this region.

Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered caught in the process of forming, and the most recent of these was found just weeks ago.

With stay-at-home orders during the COVID-19 pandemic, youth spent more time at home with family and were more isolated from in-person interaction with peers. Largely due to this social isolation from peers, substance use among youth declined, according to researchers.

Scientists gained new insights into RNA-mediated regulation of proteins (riboregulation) and its role in controlling cell growth, and most importantly how undifferentiated cells (embryonic stem cells) transform into specialised cells (e.g., liver cells). They discovered this while studying how mRNA molecules bind to and regulate ENO1, an enzyme involved in glucose metabolism. This contrasts to most previous studies, which focused on how proteins regulate RNA, this one shows that an RNA regulates a protein. Читать дальше...

A combination of ecological field methods and cutting-edge artificial intelligence has helped an interdisciplinary research group detect eelgrass wasting disease at nearly three dozen sites along a 1,700-mile stretch of the West Coast, from San Diego to southern Alaska.

Researchers have discovered two new species of crocodiles that roamed parts of Africa between 18 million and 15 million years ago and preyed on human ancestors. The giant dwarf crocodile species, called Kinyang, mysteriously disappeared, possibly due to changes in the climate.

A new study describes the short- and long-term neurological symptoms of SARS-CoV-2 infection, and identifies a new group of COVID-19 long-haulers with advanced motor and cognitive symptoms.

Higher exposure to air pollution is associated with higher functional brain connectivity among several brain regions in preadolescents, while exposure to traffic noise was not, according to a study. The findings also identify the first years of life as the most sensitive period of exposure to air pollution.

Initial results of the Canadian OPTIMA study comparing the efficacy of two models of care for treating opioid use disorder have been completed.

The Black Death, the biggest pandemic of our history, was caused by the bacterium Yersinia pestis and lasted in Europe between the years 1346 and 1353. Despite the pandemic's immense demographic and societal impacts, its origins have long been elusive. Now, scientists have obtained and studied ancient Y. pestis genomes that trace the pandemic's origins to Central Asia.

Researchers have identified a molecule in the blood that is produced during exercise and can effectively reduce food intake and obesity in mice.

The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work demonstrates a new technique for identifying the precursors of the most extreme galactic environments.

Older adults who have worse physical health or mental health, and those with more chronic conditions, are more likely to have experienced many forms of ageism.

The process that allows bacteria to expand and grow while maintaining the strength of the cell walls has been identified as offering a potential new target for antibiotics.

Scientists have found a way to identify and interpret 'signatures' that reveal the complex genetic causes of some of the deadliest cancers -- which often have a survival rate of less than 10%. The results could allow them to develop more accurate treatments and significantly improve survival rates.

Qubits, the basic building blocks of quantum computers, are as fragile as snowflakes. Now, researchers have come up with a new way of reading out the information from certain kinds of qubits without destroying them in the process, potentially paving the way for a quantum internet.

A newly developed test could help doctors more accurately predict whether individuals who undergo gastric bypass surgery will experience a remission of type 2 diabetes within two years of the procedure.

High-intensity focused ultrasound (HIFU) can help some men with prostate cancer avoid surgery or radiation.

Experts at the University of Bristol have discovered that the scales on moth wings act as excellent sound absorbers even when placed on an artificial surface.

English Bulldogs must be bred with more moderate physical features, experts say, as a new study reports that the breed is significantly less healthy than other dog breeds. English Bulldogs are at increased risk of breathing, eye, and skin conditions due to their extreme physical features, including shortened muzzles, folded skin, and a squat body, reports a recent article.

Studying the unusual social behavior of an Australian native bee has enabled researchers to obtain a clear understanding of the earliest stages of social evolution. Evidence of how individuals that live a solitary lifestyle can transition to colonial life unlocks a key biological question about evolution, they say.
