Some industrial processes used to create useful chemicals require heat, but heating methods are often inefficient, partly because they heat a greater volume of space than they really need to. Researchers including those from the University of Tokyo devised a way to limit heating to the specific areas required in such situations. Their technique uses microwaves, not unlike those used in home microwave ovens, to excite specific elements dispersed in the materials to be heated. Their system proved to be around 4.5 times more efficient than current methods. While there’s more to climate ...

The vast majority of consumer electronics use lithium-ion batteries, and with each generation, these devices are designed smaller, lighter and with longer battery life to meet the growing demands of consumers. Each new iteration also brings the batteries that power the devices closer to the limits of their size, weight and performance. Researchers are constantly testing new approaches and materials for making lightweight, high-performance components. The latest contender is MXene, a type of metallically conductive two-dimensional nanomaterial discovered by Drexel University researchers ...

MIAMI, FLORIDA (Oct. 10, 2025) – Women living close to federally designated Superfund sites are more likely to develop aggressive breast cancers — including the hard-to-treat triple-negative subtype — according to new studies from Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine. According to a National Institutes of Health study, some especially aggressive forms of breast cancer that are resistant to treatment are on the rise.  Now, three recent ...

Glaciers are fighting back against climate change by cooling the air that touches their surfaces. But for how long? The Pellicciotti group at the Institute of Science and Technology Austria (ISTA) has compiled and re-analyzed an unprecedented dataset of on-glacier observations worldwide. Their findings, published today in Nature Climate Change, demonstrate that glaciers will likely reach the peak of their self-cooling power by the next decade before their near-surface temperatures spike up and melting accelerates. Thomas Shaw keeps a vivid memory of this special summer day in August 2022. The postdoctoral researcher in Francesca Pellicciotti’s group at the Institute of Science ...

Some people flip off the lights the moment they leave a room, while others rarely think twice about saving energy. According to the most comprehensive analysis of people’s sentiments toward household energy savings to date, publishing October 10 in the Cell Press journal Cell Reports Sustainability, people’s attitudes and moral sentiments about their energy usage—rather than income or knowledge of how to conserve power—determine whether they take action at home.   Domestic energy usage accounts for about a fifth of all energy consumption in the United States and European Union. Understanding what matters ...

Light is fast, but travels in long wavelengths and interacts weakly with itself. The particles that make up matter are tiny and interact strongly with each other, but move slowly. Together, the two can combine into a hybrid quasiparticle called a polariton that is part light,  part matter. In a new paper published today in Chem, a team of Columbia chemists has identified how to combine matter and light to get the best of both worlds: polaritons with strong interactions and fast, wavelike flow. These distinctive behaviors can be used to power optical computers and other light-based quantum ...

Scientists have identified an unusual type of brain cell that may play a vital role in progressive multiple sclerosis (MS), likely contributing to the persistent inflammation characteristic of the disease. The discovery, reported today in Neuron, is a significant step towards understanding the complex mechanisms that drive the disease and provides a promising new avenue for research into more effective therapies for this debilitating condition. MS is a chronic disease in which the immune system mistakenly attacks ...

Researchers have demonstrated a new and sustainable way to make the chemicals that are the basis of thousands of products – from plastics to cosmetics – we use every day. Hundreds of thousands of chemicals are manufactured by the chemical industry, which transforms raw materials – usually fossil fuels – into useful end products. Due to its size and its use of fossil fuel feedstocks, the chemical industry is responsible for roughly 6% of global carbon emissions. But researchers, led by the University of Cambridge, are developing new methods ...

Higher levels of screen time in early childhood are associated with lower scores in reading and mathematics on Ontario’s standardised tests, with each additional hour of daily screen time associated with a 10 per cent drop in the likelihood of achieving higher academic levels. Published in JAMA Network Open, the findings are part of a new study from TARGet Kids!, a collaborative research network co-led by Dr. Catherine Birken at The Hospital for Sick Children (SickKids) and Dr. Jonathon Maguire at Unity Health Toronto’s St. Michael’s Hospital.  The study followed more than 3,000 children across Ontario from 2008 to 2023. Researchers ...

About The Study: In this cohort study, early extracranial surgery was associated with adverse function, cognition, and disability after traumatic brain injury (TBI) rated as moderate-severe or with radiographic abnormalities on computed tomography (CT) scan regardless of Glasgow Coma Scale at index admission but not after orthopedic trauma or CT− TBI. Further studies may help determine whether surgical timing or other interventions can improve the observed long-term deficits.  Corresponding ...

About The Study: In this cohort study of employed workers in the U.S., the new year-round baseline for work absences appeared to be on par with the levels formerly confined to pre-pandemic influenza season conditions. Policymakers should consider the consequences for workers, including the value of policies and actions that mitigate the spread of COVID-19 in the workplace. This study additionally highlights the potential for using nationally representative labor market data to monitor the impacts of ...

About The Study: The findings of this study suggest that elimination of race-conscious admissions coincided with declines in medical school diversity, threatening progress toward health care equity. Medical schools must explore alternative admissions strategies, such as holistic review processes that account for structural barriers. Without such efforts, reduced diversity in medical education may worsen existing health disparities.  Corresponding Author: To contact the corresponding author, Natalie Florescu, MD, MPH, email natalie.florescu@uvmhealth.org.

About The Study: In this cohort study, 40% of orders for glucagon-like peptide-1 receptor agonists (GLP-1RAs) were not filled. Non-Hispanic Black patients and Hispanic patients were less likely to fill orders than non-Hispanic white patients, and the non-Hispanic Black and Hispanic patients who filled their orders paid lower out-of-pocket costs. Out-of-pocket differences across groups may stem from differences in insurance coverage, use of different GLP-1RAs, or different cost thresholds for forgoing GLP-1RAs. Corresponding Author: To contact the corresponding ...

In a secondary analysis of a study of 200 classrooms, Mass General Brigham researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed School is in session, and viral illness is on the rise. A new study suggests that lowering exposure to respiratory viruses in classrooms isn’t as simple as adding high-efficiency particulate air (HEPA) purifiers to the room. In a secondary analysis of a randomized clinical trial, investigators from Mass General Brigham and their colleagues found that exposure to respiratory viruses in the air were ...

UVA Health lung researchers are developing a promising approach to detecting patients at risk of interstitial lung disease (ILD), an increasingly common condition that is a leading reason for lung transplants. The approach could accelerate the development of new and better treatments with more tolerable side effects than existing options. The UVA scientists have already discovered biological indicators in the blood – “biomarkers” – that can predict the survival chances of patients with ILD. But the researchers, led by John S. Kim, MD, believe these types of biomarkers can be used for far more: The scientists are aiming to determine if biomarkers ...

Treatments for cancer are continuously improving, but they can still cause debilitating, even fatal, side effects. Immune checkpoint inhibitors, or ICIs, have revolutionized cancer therapy, yet their use can trigger a rare but deadly side effect that affects the heart: myocarditis. ICI-related myocarditis has a mortality of up to 40%. The adverse side effects caused by ICIs are immune-related. The immune system becomes hyperactive and attacks tissue that is healthy, not cancerous. In ICI-related myocarditis, ...

Recent research has achieved significant advances in acoustofluidic technologies for efficient isolation and biomarker-specific detection of small extracellular vesicles (sEVs). Nevertheless, rapid and high-sensitivity analysis of low-volume clinical samples remains challenging, often requiring multi-step preprocessing and bulky instrumentation. By integrating sharp-edge microstructures with acoustically induced vortices, we enable size-selective concentration of target-bound complexes for immediate fluorescence readout. "The acoustofluidic chip leverages localized acoustic streaming to spatially separate microbead-sEV conjugates from ...

Cancer remains a leading cause of global morbidity and mortality. Traditional therapies like chemotherapy and radiotherapy are often limited by their lack of specificity, leading to systemic toxicity and the emergence of drug resistance. Nanoparticles, with dimensions ranging from 1 to 100 nm, offer a sophisticated solution. Their unique physicochemical properties allow them to navigate biological barriers and can be engineered for active targeting (e.g., using ligands for overexpressed cancer cell receptors) or passive targeting (exploiting the Enhanced Permeability and Retention effect of tumor vasculature). The cellular uptake ...
