A clinical trial at four pediatric diabetes centers in the United States has found that a new artificial pancreas system -- which automatically monitors and regulates blood glucose levels -- is safe and effective at managing blood glucose levels in children as young as age six with type 1 diabetes.

Researchers have looked at how much water conservation can readily and affordably be achieved in each region and industry by looking at what conservation measures were already working and considering how much water is being used.

The inherited disease, which typically kills children before their second birthday, has no cure, but a new study in a canine model offers hope for an effective gene therapy with lasting results.

Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work exploring the energetic costs of computation within the context of Turing machines.

Rules which stipulate a single specific physical distance (1 or 2 metres) between individuals to reduce the spread of covid-19 are based on outdated science and experiences of past viruses, say researchers in a new article.

Two different interventions both worked to significantly reduce the rate of inappropriate antibiotic prescriptions made by physicians in a telemedicine practice, a new study shows. The finding could offer a new way to stem the growing problem of antibiotic resistance, particularly as telemedicine grows due to the ongoing COVID-19 pandemic.

Scientists have discovered possible biological markers that they hope could one day help identify the presence of an opioid use disorder during human pregnancy.

Cerebral venous thrombosis (CVT) occurs when a blood clot forms in one of the veins in the brain, preventing blood from draining out of the brain. A new analysis has found that the incidence of CVT in the United States is higher than previously reported and has increased over time.

New mathematical modeling shows that U.S. political parties are becoming increasingly polarized due to their quest for voters -- not because voters themselves are becoming more extremist.

A Seattle fishing vessel that departed port in May returned 18 days later with an unusual haul: the first human evidence that neutralizing antibodies provide protection from reinfection by SARS-CoV-2.

When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the light from these 'tidal disruption events' (TDEs) for clues to the feeding behavior of the supermassive black holes lurking at the centers of galaxies, and new observations help resolve crucial...

New research examining the crystal structure of the silica mineral quartz under shock compression is challenging longstanding assumptions about this ubiquitous material.

In one study, researchers have identified six molecules that can be used as biomarkers to predict how severely ill a patient will become. In another study, they reveal a new mechanism causing blood clots in COVID-19 patients and potential ways to treat them.

Through an analysis of the Fermi data and an exhaustive series of modeling exercises, researchers were able to determine that an observed excess of gamma rays could not have been produced by what are called weakly interacting massive particles, most popularly theorized as the stuff of dark matter.

Biomedical engineers have shown that the effectiveness of a two-pronged type 2 diabetes treatment increases when the drugs are linked by a heat-sensitive tether rather than concurrently administered. The combination molecule forms a gel-like depot under the skin that slowly releases the drug. These findings suggest that this approach to combination drug design could be applied to disease therapies...

In the American Southwest, native desert bighorn sheep populations found in landscapes with minimal human disturbance, including several national parks, are less likely to be vulnerable to climate change.

A potential therapy for obesity would transplant HUMBLE (human brown-like) fat cells, human white fat cells that have been genetically modified using CRISPR to become similar to heat-generating brown fat cells.

Molecules known as tRNAs are often overlooked in studies of disease processes. Researchers have found that a mutation in a tRNA gene called n-Tr20 -- expressed only in the brain -- can disrupt the landscape of entire cells, leading to chain reactions that alter brain function and behavior.

A new study finds that the success rate of summiting Mount Everest has doubled in the last three decades, even though the number of climbers has greatly increased, crowding the narrow route through the dangerous 'death zone' near the summit. However, the death rate for climbers has hovered unchanged at around 1% since 1990.

Scientists have nailed down the temperature of the last ice age -- the Last Glacial Maximum of 20,000 years ago - to about 46 degrees Fahrenheit.

A new study says that many of the ice shelves ringing Antarctica could be vulnerable to quick destruction if rising temperatures drive melt water into the numerous fractures that currently penetrate their surfaces. The shelves help slow interior glaciers' slide toward the ocean, so if they were to fail, sea levels around the world could surge rapidly as a result.

Early in the COVID-19 pandemic, researchers found that anticoagulation therapy was associated with improved survival among hospitalized COVID-19 patients. But many questions remained -- about the size of the potential benefit, and about what dosage of this therapy might be more effective. New research suggests some possible answers.

A new study has discovered the key calcium channel responsible for closing plant pores as an immune response to pathogen exposure. The findings are a major step toward understanding the defense mechanisms plants use to resist infection, which could eventually lead to healthier, more resistant and more productive crops.

The change from Middle Stone Age (MSA) to Later Stone Age (LSA) marks a major cultural change amongst our hunter-gatherer ancestors, but distinguishing between these two industrial complexes is not straightforward. New researc demonstrates how machine learning can provide a valuable tool for archaeologists, and can identify what differentiates the MSA and LSA.
