A lack of the mineral selenium in the diet puts people at risk of paracetamol overdose, even when the painkiller is taken at levels claimed to be safe on the packaging, according to collaborative research emerging from the University of Bath and Southwest University in China.
The size of a fly's eyes and nose reflect both its behaviour during mating and its habitat preferences, according to a new study published today in eLife.
The findings could help explain how new species of flies evolve over time, as selective pressures such as light availability and competition for habitat drive a fundamental compromise between the size of different sensory organs.
DURHAM, N.C. - Biomedical engineers at Duke University have demonstrated a method for controlling the phase separation of an emerging class of proteins to create artificial membrane-less organelles within human cells. The advance, similar to controlling how vinegar forms droplets within oil, creates opportunities for engineering synthetic structures to modulate existing cell functions or create entirely new behaviors within cells.
The results appear online on August 3 in the journal Nature Chemistry.
Scientists at Huntsman Cancer Institute (HCI) at the University of Utah (U of U) report today the development of new models to study molecular characteristics of tumors of the lung and pancreas
Scientists at Huntsman Cancer Institute (HCI) at the University of Utah (U of U) report today the development of new models to study molecular characteristics of tumors of the lung and pancreas that are driven by mutations in a gene named NTRK1. The findings were published today in the journal Cell Reports.

CAMBRIDGE, MA -- Humans began to develop systems of reading and writing only within the past few thousand years. Our reading abilities set us apart from other animal species, but a few thousand years is much too short a timeframe for our brains to have evolved new areas specifically devoted to reading.
PULLMAN, Wash. - With social media use being as prevalent as ever, a new study from Washington State University's Edward R. Murrow College of Communication shows that adolescents may share marijuana-related content on social media in an effort to fit in with their peers.
Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions - delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under construction in France to demonstrate the feasibility of fusion power.

NASA's CloudSat passed over Tropical Storm Isaias as it was strengthening back into a hurricane on Aug. 3, and before it made landfall in North Carolina. CloudSat revealed areas of heavy rain and ice particles in high, powerful clouds.
New research from Boston Medical Center found that patients experiencing severe COVID-19 symptoms had improved outcomes when administered an Interleukin-6 (IL6ri) inhibitor, sarilumab or tocilizumab, given to mediate severe systemic inflammatory responses. The treatment was more effective when administered earlier in the disease course and reduced mortality rates and the need for intubation.
Gales and rainstorms brought by landfalling typhoons cause extensive casualties and losses of property every year in many coastal areas of the western Pacific. As such, predicting the track and precipitation of typhoons has always been a top priority of weather forecasting. The structural characteristics of the typhoon and the state of the surrounding environment will directly affect the development trend and track of the typhoon.
More than 1,000 bottlenose dolphins (Tursiops truncatus) live in the Indian River Lagoon year-round. The estuary system along the central east coast of Florida stretches about 250 kilometers and provides valuable shallow water habitat for this species. The lagoon also is popular for recreational fishing spots, which often coincide with bottlenose dolphin feeding habitats because they target the same species of fish. In fact, it very common to observe interactions between dolphins and recreational fishermen.
CORVALLIS, Ore. - As a first-year graduate student studying truffle ecology at Oregon State University, Dan Luoma attended a scientific meeting in 1981 on Orcas Island in Washington. Having recently learned how to search for truffles, he went out one day of the meeting looking for the prized fungi and found a collection.
He brought them back to Oregon State and showed them to his mentor James Trappe, who confirmed the collection was of an undescribed species. Trappe added it to the university's collection. Then it sat there.
A notable characteristic of several neurodegenerative diseases, such as Alzheimer's and Parkinson's, is the formation of harmful plaques that contain aggregates--also known as fibrils--of amyloid proteins. Unfortunately, even after decades of research, getting rid of these plaques has remained a herculean challenge. Thus, the treatment options available to patients with these disorders are limited and not very effective.
Fake audio or video content has been ranked by experts as the most worrying use of artificial intelligence in terms of its potential applications for crime or terrorism, according to a new UCL report.
