A new study highlights a surprising lens for tracking pollution trends over centuries: preserved plants and animals housed at natural history museums around the world. According to Shane DuBay, a researcher at The University of Texas at Arlington, these specimens contain valuable environmental data that can help scientists reconstruct pollution trends spanning more than 200 years. “We often lack the historical pollution data needed to understand the links between environmental contamination and long-term health effects, such as cancer, asthma, cognitive disorders and premature ...

A research team from the Institute of Modern Physics and Sichuan University has performed a direct measurement of the 12C+12C fusion reaction at a center-of-mass energy of 2.22 MeV using the LEAF accelerator facility. The experiment employed a highly intense 12C2+ beam, a highly oriented pyrolytic graphite (HOPG) target known for its low background, and a ΔE–E telescope combining a Time Projection Chamber and silicon detectors. This setup enabled detection of extremely rare fusion events, with a thick-target yield on the order of 10−17 ...

In the world of microorganisms, microbes compete for turf, spew chemicals at foes, and sometimes exploit the microscopic terrain to gain an edge. In a study published June 4 in the Cell Press journal Biophysical Journal, researchers found that bacteria can speed up by using the fluid pockets shaped by neighboring yeast cells. These microscopic moisture trails allow bacteria to swim farther and spread faster—revealing a new way for microbes to travel through soil, plants, and the human body.  “When studying microbial interactions, research often focuses on the chemical nature of these interactions,” says lead author Divakar Badal of Cornell University. ...

Scientists at the Institute for Basic Science (IBS) have uncovered a non-invasive method to boost the brain’s natural waste drainage system—a discovery that could open new avenues for tackling age-related neurological disorders. In a study published in Nature, researchers from the IBS Center for Vascular Research, led by Director KOH Gou Young, along with senior researchers JIN Hokyung, YOON Jin-Hui, and principal researcher HONG Seon Pyo, demonstrated that precisely stimulating the lymphatics under skin on the neck and face can significantly enhance the flow of cerebrospinal ...

In a UNSW-led Nature study published today, researchers say that an off-the-scale marine heatwave in the North Atlantic Ocean in 2023 was caused by record-breaking weak winds combined with increased solar radiation – all on the back of ongoing climate change. From Greenland to the Sahara and across to the Americas, the waters of the North Atlantic Ocean warmed at an unprecedented speed in the summer of 2023. “The intensity of the warming in that single summer was equivalent to about two decades worth of warming for the North Atlantic,” says lead author Professor Matthew England from UNSW Sydney. “While ...

What if your brain had a built-in map – not of places, but of possible futures? Researchers at the Champalimaud Foundation (CF) blend neuroscience and artificial intelligence (AI) to reveal that populations of dopamine neurons in the brain don’t just track whether rewards are coming – they encode maps of when those rewards might arrive and how big they might be. These maps adapt to context and may help explain how we weigh risks, and why some of us act on impulse while others hold back. Strikingly, this biological ...

A new study has revealed for the first time that ancient carbon, stored in landscapes for thousands of years or more, can find its way back to the atmosphere as CO₂ released from the surfaces of rivers. The findings, led by scientists at the University of Bristol and the cover story of the journal Nature, mean plants and shallow soil layers are likely removing around one gigatonne more CO₂ each year from the atmosphere to counteract this, emphasising their pivotal and greater part in combating climate change. Lead author Dr Josh ...

A study initiated by a University of Arizona Comprehensive Cancer Center physician-scientist defined for the first time how loss of the Y chromosome in male immune cells negatively affects immune system function, which may explain why loss of Y is associated with lower cancer survival rates. The paper “Concurrent loss of the Y chromosome in cancer and T cells impacts outcome,” was published today in Nature. In males, each cell in the body usually contains one X and one Y chromosome. “Loss of Y” is a common, nonhereditary ...

When cancer cells in male patients and immune cells in their tumors both lose the Y chromosome, those patients tend to experience poorer outcomes than patients without Y chromosome loss, according to new findings from Cedars-Sinai investigators. Their work, published in the scientific journal Nature, could lead to ways to make some cancer treatments more effective. The Y chromosome is one of two chromosomes that determine biological sex in mammals. Females have two X chromosomes, males have one X and one Y chromosome, and it ...

(Santa Barbara, Calif.) — Hot air holds more moisture. That’s why you can blow your hair dry even after a steamy shower. It’s also what dumps rain in the tropics and sucks water from desert soils. A new study, published in Nature, shows that the atmosphere’s growing thirst for water is making droughts more severe, even in places where rainfall has stayed the same. The paper details how this “thirst” has made droughts 40% more severe across the globe over the course of the past 40 years. “Drought is based on the difference between water supply (from precipitation) and atmospheric water demand. ...

A new University of British Columbia-led study is shedding light on a long-overlooked consequence of colorectal cancer: the lasting toll it can take on women’s sexual health, even years after treatment ends. Researchers analyzed health data from more than 25,000 women in B.C. diagnosed with colorectal cancer between 1985 and 2017, comparing their experiences to those of cancer-free women. Cancer treatments such as surgery, chemotherapy and radiation were linked to a range of long-term sexual health issues, including a 67 per cent higher risk of dyspareunia—pain during sex—a ...

(Philadelphia, PA) – A novel screening approach developed by physicians at the Lewis Katz School of Medicine at Temple University shows significant promise for improving the detection of pulmonary arterial hypertension (PAH)—a life-threatening form of heart failure related to high blood pressure in the lung circulation that is often overlooked due to vague symptoms such as fatigue and shortness of breath. The new research, published online April 5 in the American Heart Journal, shows that the virtual echocardiography screening ...

PULLMAN, Wash.--A group of bat viruses closely related to the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) could be one small mutation away from being capable of spilling over into human populations and potentially causing the next pandemic. A recent study published in the journal Nature Communications examined an understudied group of coronaviruses known as merbecoviruses — the same viral subgenus that includes MERS-CoV — to better understand how they infect host cells. The research ...

One-pot recipes make preparing meals quick and easy. And one-pot 3D-printing could do the same for additive manufacturing. Now, researchers publishing in ACS Central Science have demonstrated a new resin that simultaneously creates solid objects and dissolvable structural supports, depending on what type of light the resin is exposed to. The approach could increase the applications for 3D-printed objects, including tissue engineering scaffolds, joints and hinges. “Vat photopolymerization is known for its fast and high-resolution printing, but one of the most nerve-wracking parts after printing is manually removing supports for intricate interlocking and overhang ...

You may have seen it in the news recently: a baby in Pennsylvania with a rare genetic disorder was healed with a personalized treatment that repaired his specific genetic mutation. The treatment was created using a form of gene editing called base editing —a method created by Alexis Komor when she was a postdoctoral scholar in molecular biologist David Liu’s group at Harvard University. Since that work was published in 2016, Komor, who is now an associate professor of chemistry and biochemistry at the University of California San Diego, has continued to study base-editing tools to better understand and further develop their capabilities. ...

A team led by University of Virginia School of Medicine researcher James Stone, MD, PhD, has received $3.2 million from the federal Department of Defense to enhance a critical tool for protecting the brain health of military personnel.  The project aims to upgrade the Generalized Blast Exposure Value (GBEV) tool that assigns a numerical score to a service member’s history of blast exposures that can be used to assess the potential for adverse health outcomes.  “This will represent a major step forward in how the military monitors, protects and cares for its service members,” said Stone, a UVA Health ...

At home in Australia, Mark Renton started playing football as soon as he could. He figured it would eventually lead to a career prescribing strength training and exercise regimens to athletes. But as an undergraduate, the sports science curriculum included an exercise metabolism course that explored how cells turn energy into movement. This biological focus captured Renton’s imagination, and he became increasingly interested in the mechanisms that underly muscle function, including developing force through contractions that mediate precise movements. Ultimately, Renton wound up earning a doctorate ...

DARIEN, IL – A new study to be presented at the SLEEP 2025 annual meeting found that bedtime procrastination in young adults is associated with specific personality traits, including depressive tendencies. Results show that bedtime procrastination was associated with higher neuroticism and lower conscientiousness and extraversion. These results remained significant after statistically adjusting for chronotype. “Our study demonstrated that individuals who habitually procrastinate their bedtime were actually less likely to report seeking out exciting, engaging, or enjoyable activities,” said lead author Steven Carlson, ...
