Organofluorine compounds — sometimes called ‘forever chemicals’ — are increasingly turning up in our drinking water, oceans and even human blood, posing a potential threat to the environment and human health. Now, researchers at The University of Texas at Austin have developed a way to fingerprint them, which could help authorities trace them to their source when they end up in aquifers, waterways or soil. The technique involves passing samples through a strong magnetic field then reading the burst of radio waves their atoms emit. This reveals ...

Every year, life-threating invasive fungal infections afflict more than 2 million individuals globally. Mortality rates for these infections are high, even when patients receive treatment. Aspergillus fumigatus, the most frequent cause of invasive fungal infection in people with suppressed immune systems, is responsible for approximately 100,000 deaths annually around the world. Poor treatment outcomes result from therapeutic failures and the fungi’s resistance to existing drugs. A new multi-institutional study led by researchers at Michigan State University has characterized how fungi adapt to restructure their cell walls, effectively ...

Solving a decades-old problem, a multidisciplinary team of Caltech researchers has figured out a method to noninvasively and continually measure blood pressure anywhere on the body with next to no disruption to the patient. A device based on the new technique holds the promise to enable better vital-sign monitoring at home, in hospitals, and possibly even in remote locations where resources are limited.   The new patented technique, called resonance sonomanometry, uses sound waves to gently stimulate resonance ...

Researchers working on large artificial intelligence models like ChatGPT have vast swaths of internet text, photos and videos to train systems. But roboticists training physical machines face barriers: Robot data is expensive, and because there aren’t fleets of robots roaming the world at large, there simply isn’t enough data easily available to make them perform well in dynamic environments, such as people’s homes. Some researchers have turned to simulations to train robots. Yet even that process, which often involves a graphic designer ...

CORNELL UNIVERSITY MEDIA RELATIONS OFFICE FOR RELEASE: August 7, 2024 Kaitlyn Serrao 607-882-1140 kms465@cornell.edu When is too much knowledge a bad thing? ITHACA, N.Y. – A new study finds an increase in knowledge could be a bad thing when people use it to act in their own self-interest rather than in the best interests of the larger group. Cornell University economics professor Kaushik Basu and Jörgen Weibull, professor emeritus at the Stockholm School of Economics, are co-authors ...

Many organisms react to the smell of deadly pathogens by reflexively avoiding them. But a recent study from the University of California, Berkeley, shows that the nematode C. elegans also reacts to the odor of pathogenic bacteria by preparing its intestinal cells to withstand a potential onslaught. As with humans, nematodes’ guts are a common target of disease-causing bacteria. The nematode reacts by destroying iron-containing organelles called mitochondria, which produce a cell's energy, to protect this critical element from iron-stealing bacteria. Iron is a key catalyst in many enzymatic reactions in cells — in particular, ...

MINNEAPOLIS – There’s some good news for people with Parkinson’s disease: The risk of developing dementia may be lower than previously thought, or dementia may occur later in the course of the disease than previously reported, according to a study published in the August 7, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. “The development of dementia is feared by people with Parkinson’s, and the combination of both a movement disorder and a cognitive disorder can be devastating to them and their loved ones,” said study author Daniel Weintraub, MD, ...

Long-term exposure to contaminants such as arsenic and nitrate in water is linked to an increased risk of various diseases, including cancers, cardiovascular diseases, developmental disorders and birth defects in infants. In the United States, there is a striking disparity in exposure to contaminants in tap water provided by community water systems (CWSs), with historically marginalized communities at greater risks compared to other populations. Often, CWSs that distribute water with higher contamination levels exist in areas that lack adequate public infrastructure or sociopolitical and financial resources. In ...

Living less than about one-third of a mile from pesticide use prior to conception and during early pregnancy could increase the risk of stillbirths, according to new research led by researchers at the Mel and Enid Zuckerman College of Public Health and Southwest Environmental Health Sciences Center.

Researchers have developed an inexpensive bandage that uses an electric field to promote healing in chronic wounds. In animal testing, wounds that were treated with these electric bandages healed 30% faster than wounds treated with conventional bandages. Chronic wounds are open wounds that heal slowly, if they heal at all. For example, sores that occur in some patients with diabetes are chronic wounds. These wounds are particularly problematic because they often recur after treatment and significantly increase the risk of amputation and death. One of the challenges associated ...

A new study published in Science Advances reveals how early mammals grew and developed during their pivotal Jurassic radiation. Using a technique called synchrotron X-ray tomography to image growth rings in fossilised tooth roots, the researchers were able to estimate lifespans, growth rates, and even the timing of sexual maturity in these ancient creatures.  “This is the first time we've been able to reconstruct the growth patterns of these early mammals in such detail,” said Dr Elis Newham, a Postdoctoral Research Associate ...

By Leah Shaffer Researchers at Wash U have spent the better part of the decade studying the ins and outs of how locusts smell, including how odors affect the insect’s behavior. In research recently published in eLife, Barani Raman, a professor of biomedical engineering at the McKelvey School of Engineering, starts to map out just how olfactory circuits are altered in driving different behavior in locusts. Neuromodulator serotonin is a key factor in triggering how locusts can go from being a “loner” to “gregarious” — otherwise known as swarming ...
