In a small trial, Mass General Brigham researchers found a drug designed to treat Celiac disease supported a more rapid return to normal activities for patients following COVID. Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious condition that can occur after a COVID-19 infection, presenting as high fevers, gastrointestinal symptoms, and life-threatening cardiac injury. A small, randomized clinical trial led by Mass General Brigham investigators found the oral drug larazotide—an experimental drug originally designed to treat Celiac disease—was both safe and effective in treating children with MIS-C. Their results ...

Increasing solar power generation in the United States by 15% could lead to an annual reduction of 8.54 million metric tons of carbon dioxide emissions, according to researchers at Rutgers, the Harvard T.H. Chan School of Public Health and Stony Brook University.   The study, published in Science Advances, found that the climate benefits of solar power differ markedly throughout U.S. regions, pinpointing where clean energy investments return the greatest climate dividends.   In 2023, 60% of U.S. electricity generation relied on fossil fuels, while 3.9% came from solar, according to the U.S. Energy Information ...

Oak Ridge National Laboratory (ORNL) researchers have overcome a barrier to using a more affordable, dry process for manufacturing the lithium-ion batteries used in vehicles and electronic devices. The resulting batteries provide greater electricity flow and reduced risk of overheating. Dry processing is a method for making electrode films that eliminates the need for wet organic solvents that require increased factory floor space, time, energy, waste disposal and startup expenses. However, dry-processed films tear easily. To address this issue, ORNL researchers incorporated long carbon fibers, then tested coin cell batteries made from ...

Some of the rainiest places on Earth could see their annual precipitation nearly halved if climate change continues to alter the way ocean water moves around the globe. In a new CU Boulder-led study published July 30 in Nature, scientists revealed that even a modest slowdown of a major Atlantic Ocean current could dry out rainforests, threaten vulnerable ecosystems and upend livelihoods across the tropics. “That’s a stunning risk we now understand much better,” said lead author Pedro DiNezio, associate professor in CU Boulder’s Department of Atmospheric and Oceanic Sciences, adding that parts of the Amazon rainforest could see up to a 40% reduction ...

A new study in Nature shows that delivering a single injection of gene therapy at birth may offer years-long protection against HIV, tapping into a critical window in early life that could reshape the fight against pediatric infections in high-risk regions. This study is among the first to show that the first weeks of life, when the immune system is naturally more tolerant, may be the optimal window for delivering gene therapies that would otherwise be rejected at older ages. “Nearly ...

Neutrinos are extremely elusive elementary particles. Day and night, 60 billion of them stream from the Sun through every square centimeter of the Earth every second, which is transparent to them. After the first theoretical prediction of their existence, decades passed before they were actually detected. These experiments are usually extremely large to account for the very weak interaction of neutrinos with matter. Scientists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg have now succeeded in detecting antineutrinos from the reactor of a nuclear power plant using the CONUS+ experiment, with a detector mass of just ...

JULY 30, 2025—Researchers at the University of Colorado Anschutz Medical Campus, Montefiore Einstein Comprehensive Cancer Center (MECCC), and Utrecht University have found the first direct evidence that common respiratory infections, including COVID-19 and influenza, can awaken dormant breast cancer cells that have spread to the lungs, setting the stage for new metastatic tumors. The findings published today in Nature, obtained in mice, were supported by research showing increases in death and in metastatic lung disease among cancer survivors infected with SARS-CoV-2, the virus that causes COVID-19. “Our findings indicate that individuals with a history of ...

About The Study: In this cohort study, the likelihood of receiving stroke treatments increased for white but not Black patients within the same facility after the center was stroke certified as a primary stroke center or a thrombectomy-capable or comprehensive stroke center. These within-hospital racial differences serve as sobering evidence that racial disparities in stroke care persist despite increased access to care.  Corresponding Author: To contact the corresponding author, Renee Y.

About The Study: Although nonsurgeon physicians have lower mortality rates than other highly educated professionals, this mortality benefit does not extend to surgeons. Because surgeons and nonsurgeon physicians have similar levels of health care knowledge and resources, higher mortality rates among surgeons might reflect differences related to work environment, professional demands, and lifestyle. The results of this study indicate that several causes of death (e.g., motor vehicle collisions), disproportionately affect surgeons, aligning ...

A lot of the climate-altering carbon pollution we humans release into the atmosphere by burning fossil fuels gets drawn into Earth’s oceans and landscapes through natural processes, mostly through photosynthesis as plants turn atmospheric carbon dioxide into biomass. Efforts to slow the climate crisis have long sought to harness nature, often through carbon “offsets,” aimed at bolstering forests, wetlands, and agriculture, but have generally had only marginal success so far. A new approach: contributions ...

About The Study: This review synthesizes the latest policies and initiatives concerning representation in clinical research and provides a strategic framework to ensure scientific validity of clinical trials by operationalizing broad representation at all levels.

A new study by investigators from Mass General Brigham examined the effects of policies banning flavored e-cigarettes on adults and young people. Investigators found that e-cigarette use significantly declined among young adults and adults in states that had enacted flavor bans relative to states that did not. However, declines in cigarette smoking also slowed in those states with flavor bans relative to other states—a potential unintended consequence of the bans. Results are published in JAMA Network Open. “Both ...

Liver cancer cells thrive on fat, posing a serious risk of cancer diagnosis for millions of people living with fatty liver disease. But researchers at McMaster University in collaboration with Espervita Therapeutics have developed a promising new treatment that helps the immune system attack and destroy these tumours. The discovery, detailed in a study published in Nature on July 30, 2025, opens new possibilities for slowing tumour growth and empowering the body’s natural defences. This is particularly important, as current treatments for ...

CHICAGO --- Most U.S. adults have a “heart age” several years older than their chronological age — sometimes by more than a decade. And that gap is wider among men and among those with lower incomes or education or who identify as Black or Hispanic, according to a new study led by Northwestern Medicine. As part of the study, the Northwestern scientists created a free online tool that calculates a person’s “heart age” based on their risk for cardiovascular disease, using routine health data such as blood pressure, cholesterol levels and whether ...

The tumor microenvironment (TME) represents a highly complex system that encompasses cellular components (such as cancer cells, stromal cells, and immune cells) and non-cellular components (such as blood vessels and signaling molecules)[1-3]. These diverse components engage in complex interactions with tumor cells and undergo dynamic changes during tumor progression. Specifically, intratumoral microbial metabolites play an important role on the TME. The metabolic products of these microorganisms encompass a range of bioactive molecules, including lactate, amino acids, short-chain fatty acids (SCFAs), bile acids, trimethylamine N-oxide, and inosine. These metabolites, ...

About The Study: Transparency of evidence supporting Food and Drug Administration (FDA) authorization of artificial intelligence (AI)- and machine learning -based devices for Alzheimer disease and related dementias was limited, precluding effective evaluation of training and validation dataset representativeness. Disease status (i.e., dementia type and distribution), age, and sex were reported for fewer than half of devices, while race and ethnicity data were rarely disclosed, raising uncertainty about real-world generalizability and clinical accuracy in intended populations.  Corresponding Author: To contact the corresponding ...

About 80% of people have the fungus Candida albicans in their gut. Although most of the time it persists unnoticed for years causing no health problems, C. albicans can turn into a dangerous microbe that causes serious diseases in many organs, including the urinary tract, lungs and brain. Understanding how this fungus colonizes the gut is key to preventing it from becoming harmful. Working with a mouse model, researchers at Baylor College of Medicine and international collaborators have discovered unexpected factors that help C. albicans ...

Recent climate-related crises — from severe storms and flooding to extreme heat — have raised new questions about how local governments communicate the risk of these crises and what they are doing to keep their citizens safe. To better understand what this communication looks like at local level, and the factors that may be shaping it, researchers from Drexel University analyzed climate resilience planning information available on the public-facing websites of 24 coastal communities in New Jersey that are contending with the effects of sea level rise. Their report, recently published in the Journal of Extreme Events, ...

A new technology that harnesses AI to analyze mammograms and improve the accuracy of predicting a woman’s personalized five-year risk of developing breast cancer has received Breakthrough Device designation from the Food and Drug Administration (FDA). Developed by researchers at Washington University School of Medicine in St. Louis, the software has been licensed to Prognosia Inc., a WashU startup company. The system analyzes mammograms to produce a risk score estimating the likelihood that a woman will develop breast cancer over the next five years. The technology is ...

True or false? “It is safe to take an over-the-counter medicine to help you sleep, even if you are drunk on alcohol.” “Driving while high on THC (cannabis) is safe.” “Using psychedelics is safe for everyone.” None of those statements is true. But young men who take a passive approach to news and information—consuming whatever flows over their social media transoms—were likely to believe them in a national survey conducted by Washington State ...

Decades ago, archaeologists discovered a sticky substance in a copper jar in an ancient Greek shrine. And until recently, the identity of the residue was still murky — is it a mixture of fats, oils and beeswax or something else? Researchers publishing in the Journal of the American Chemical Society have reanalyzed samples of the residue using modern analytical techniques and determined that it’s likely the remains of ancient honey — a conclusion previous analyses rejected. Honey was an important substance in the ancient world, sometimes left in shrines as offerings ...

The COVID-19 pandemic has placed enormous pressure on healthcare systems and economies around the world, with particularly severe impacts on vulnerable groups like residents of long-term care facilities (LTCFs). One key lesson from the pandemic is that early detection and treatment can lower hospitalization and death rates while also cutting medical costs. Wastewater surveillance at treatment plants (WSTPs) has emerged as a low-cost and innovative method to detect outbreaks early. Many developed countries have adopted this approach, ...
