Bacteria modify their ribosomes when exposed to widely used antibiotics, according to research published today in Nature Communications. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance. Escherichia coli is a common bacterium which is often harmless but can

A new study led by King’s College London has provided further evidence that the deaths of 350 African elephants in Botswana during 2020 were the result of drinking from water holes where toxic algae populations had exploded due to climate change. The lead author of the report says their analysis shows animals were very likely […]

A tiny, four-fingered “hand” folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, University of Illinois Urbana-Champaign researchers report. Dubbed the NanoGripper, the nanorobotic hand also could be progr

Researchers have quantified for the first time the global emissions of a sulfur gas produced by marine life, revealing it cools the climate more than previously thought, especially over the Southern Ocean. The study, published in the journal Science Advances, shows that the oceans not only capture and redistribute the sun’s heat, but produce

Contrary to widespread concerns that global crop yields have stagnated in recent decades, a comprehensive study of worldwide food production finds yields have continued to grow at roughly the same rate since the 1960s. John Baffes of the World Bank and Xiaoli Etienne of the University of Idaho, U.S., report these findings on November 27, […]

Manmade sounds such vehicle traffic can mask the positive impact of nature soundscapes on people’s stress and anxiety, according to a new study published November 27, 2024, in the open-access journal PLOS ONE by Paul Lintott of the University of the West of England, U.K., and Lia Gilmour of the Bat Conservation Trust, U.K. Existing […]

In patients with long COVID, lower pulmonary gas exchange may be associated with impaired cognitive function, according to a study being presented next week at the annual meeting of the Radiological Society of North America (RSNA). According to the National Center for Health Statistics, approximately 17.6% of adults in the U.S. have experienced a p

Dr. Sofia Sheikh from the SETI Institute led a study that sheds new light on how pulsar signals — the spinning remnants of massive stars — distort as they travel through space. This study, published in The Astrophysical Journal, was performed by a multi-year cohort of undergraduate researchers in the Penn State branch of the […]

The current standard of care for psychosis is a diagnostic interview, but what if it could be diagnosed before the first symptom emerged? Researchers at the Del Monte Institute for Neuroscience at the University of Rochester are pointing toward a potential biomarker in the brain that could lead to more timely interventions and personalized care. [&

Regenerative medicine holds the extraordinary promise that future patients in need of new cells, tissues or organs will no longer have to rely on donors. Organ shortages and cell type mismatches will become past problems, replaced by safe, on-demand options for anyone who needs a transplant. This revolutionary field still faces many challenges, inc

Spanish explorers may have brought the first peach pits to North America, but Indigenous communities helped the ubiquitous summer fruit really take root, according to a study led by a researcher at Penn State. The study, published in Nature Communications, shows that Indigenous political and social networks and land use practices played key roles i

University of Wisconsin-Madison engineers have found a way to simultaneously mitigate three types of defects in parts produced using a prominent additive manufacturing technique called laser powder bed fusion. Led by Lianyi Chen, an associate professor of mechanical engineering at UW-Madison, the team discovered the mechanisms and identified the pr

Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ineffective. Escalating resistance by these mutants forces farmers and vector control specialists to ramp up use of pois

The Golgi apparatus modifies, sorts and packages proteins to be sent to their final destinations, whether that’s within or outside of the cell. It’s a core function, but little studied in the setting of cancer immunology, especially when compared to other organelles like the mitochondria or endoplasmic reticulum. “So we were inter

A new study from Northwestern Medicine reveals a troubling rise in severe maternal health issues and birth complications in Illinois from 2016 to 2023, closely linked to increases in chronic health conditions affecting pregnancy, such as high blood pressure, gestational diabetes, mental health disorders and especially obesity, which saw the largest

We’ve all been there. Moments after leaving a party, your brain is suddenly filled with intrusive thoughts about what others were thinking. “Did they think I talked too much?” “Did my joke offend them?” “Were they having a good time?” In a new Northwestern Medicine study, scientists sought to better underst

Just as crop-devouring insects evolve to resist pesticides, cancer cells can increase their lethality by developing resistance to treatment. In fact, most deaths from cancer are caused by the evolution of therapeutic resistance. In a new review, Arizona State University researchers, working with colleagues around the world, explore how established

A team of researchers at Clemson University used an innovative multiomics approach to identify key immune mechanisms in a chronic and debilitating inflammatory skin condition. The research, which was published in the journal Proceedings of the National Academy of Sciences (PNAS), offers a promising target for future therapies. Hidradenitis suppurat
