With growing concern about the ubiquity of toxic chemicals in consumer products, many states have passed laws aimed at protecting people from harmful substances in everyday items like cosmetics, cleaning supplies, plastics, and food packaging. California’s Proposition 65, for instance, is considered one of the most extensive toxics laws in the country. But does the law work? According to a new study published in the journal Environmental Health Perspectives, it does. “Not only have people’s exposures to specific toxic chemicals gone down in California, ...

A survey of patients receiving gender affirming care shows that commercial insurance pays for most of their treatments, they receive less care in the South than other parts of the U.S. and they deal with disproportionate levels of housing insecurity and trauma compared to others, according to a new study by researchers at the Colorado School of Public Health and the University of Colorado Anschutz Medical Campus. The study, using data provided by Kythera Labs, a healthcare clearinghouse, examined millions of insurance claims by patients undergoing gender affirming care (GA) and those not. It also looked at social determinants of healthcare (SDOH), non-medical factors ...

Microswimmers often need to independently navigate narrow environments like microchannels through porous media or blood vessels. The swimmers can be of biological origin, like algae or bacteria, but also constitute custom designed structures used for the transport of chemicals and drugs. In these cases, it is important to control how they swim in relation to walls and boundaries - as one might want them to exchange fuel or information, but also avoid them to stick where they are not supposed to. Many swimmers are electrically ...

WASHINGTON, DC – OCTOBER 28, 2024 – The first powered randomized trial examining early intervention with transcatheter aortic valve replacement (TAVR) in patients with asymptomatic, severe aortic stenosis (AS) found this strategy to be both a safe and effective alternative to clinical surveillance (CS). Findings were reported today at TCT 2024, the annual scientific symposium of the Cardiovascular Research Foundation (CRF). TCT is the world’s premier educational meeting specializing in interventional ...

Patients with late-stage cancer often have to endure multiple rounds of different types of treatment, which can cause unwanted side effects and may not always help. In hopes of expanding the treatment options for those patients, MIT researchers have designed tiny particles that can be implanted at a tumor site, where they deliver two types of therapy: heat and chemotherapy. This approach could avoid the side effects that often occur when chemotherapy is given intravenously, and the synergistic effect of the two therapies ...

WASHINGTON, DC – OCTOBER 28, 2024 – The EVOLVED trial found that early aortic valve intervention in patients with asymptomatic severe aortic stenosis (AS) and mid-wall myocardial fibrosis on magnetic resonance imaging did not reduce the incidence of the composite primary endpoint of all-cause death or unplanned aortic stenosis hospitalization compared with guideline-directed conservative management.   Findings were reported today at TCT 2024, the annual scientific symposium of the Cardiovascular Research Foundation (CRF). TCT is the world’s premier educational meeting specializing in interventional cardiovascular ...

Earlier this year, researchers at the Flatiron Institute’s Center for Computational Quantum Physics (CCQ) announced that they had successfully used a classical computer and sophisticated mathematical models to thoroughly outperform a quantum computer at a task that some thought only quantum computers could solve. Now, those researchers have determined why they were able to trounce the quantum computer at its own game. Their answer, presented on October 29 in Physical Review Letters, reveals that the quantum problem they tackled — involving ...

WASHINGTON, Oct. 29, 2024 – While many smoking rooms in U.S. airports have closed in recent years, they are still common in other airports around the world. These lounges can be ventilated, but how much does it actually help the dispersion of smoke? Research published in Physics of Fluids, by AIP Publishing, shows that not all standing positions in airport smoking lounges are created equal. Researchers from the University of Hormozgan in Iran studied nicotine particles in a simulated airport smoking room and found that the thermal environment and positioning of smokers influenced how particles ...

AURORA, Colo. (Oct. 29, 2024) –  An ancient gene mutation among First Nations inhabitants of Oceania may make them more susceptible to infectious diseases like influenza, according to a new study by scientists at the University of Colorado Anschutz Medical Campus. “We found quite a diverse set of genes in this population but there was one allele that really stood out in terms of genetic composition,” said the study’s lead author Paul Norman, PhD, professor of biomedical informatics at the University of Colorado School of Medicine. “We did some investigating, and we suspect this allele ...

New Haven, Conn. — Paleontologists have identified fossils of an ancient species of bug that spent the past 450 million years covered in fool’s gold in central New York. The new species, Lomankus edgecombei, is a distant relative of modern-day horseshoe crabs, scorpions, and spiders. It had no eyes, and its small front appendages were best suited for rooting around in dark ocean sediment, back when what is now New York state was covered by water. Lomankus also happens to be bright gold — thanks to layers of pyrite ...

Osaka, Japan—Achieving a sustainable society requires the development of advanced degradable plastics, or polymers, which are molecules composed of long chains of repeating units. The goal of a resource-circulating society is now one step closer thanks to the efforts of a team from Osaka University that has developed tough biodegradable plastics by including movable crosslinking groups. In a study published this month in Chem, the researchers have revealed that developing polymers with movable crosslinks not only increases their strength but also promotes degradation by enzymes under mild conditions. Plastics and polymers need to achieve both desirable performance ...
