EMBARGOED FOR RELEASE AT 11 A.M. ET, MONDAY, NOVEMBER 24, 2025 Highlights: A new systematic analysis shows more than half the people living in the U.S., 54%, are affected by a neurological disease or disorder. Disorders of the nervous system impacted more than 180 million of the nearly 333 million Americans in 2021 and were the top cause of health loss in the U.S. The nervous system includes the brain, spinal cord and nerves. The most prevalent conditions were tension-type headache affecting 122 million Americans, migraine affecting 58 million and diabetic neuropathy affecting 17 million. The leading causes of health loss were stroke, Alzheimer’s disease and ...

LMU researchers uncover the mechanism by which ribosomes raise alarms in the cell. Ribosomes, the protein factories of the cell, are essential for all living organisms. They bind to mRNA and move along the messenger molecule, reading the genetic code as they go. Using this information, they link amino acids to make proteins. But their function goes far beyond pure production: Ribosomes are also important sensors for cellular stress and initiate protective reactions when problems arise. An international team led by Professor Roland Beckmann from LMU’s Gene Center ...

New York, NY (November 24, 2025)—Researchers at the Icahn School of Medicine at Mount Sinai have uncovered a new way to understand how children fare after liver transplantation: by focusing not on medical test results, but on how differently parents and children perceive the child’s well-being. The findings, published in The Journal of Pediatrics, come from the first multisite prospective trial to evaluate real-time discrepancies in patient-reported outcomes for pediatric liver transplant recipients. The study included 140 parent-child pairs across seven transplant centers in the United States ...

Some tumors are almost impossible to treat. That’s especially true for carcinomas, which don’t behave like other malignancies. Some of these tumors act as shapeshifters and start to resemble cells from other organs of the human body, such as skin. This bizarre behavior presents a challenge for existing therapies. “The tumors are notoriously plastic in their cellular identity,” says Cold Spring Harbor Laboratory (CSHL) Professor Christopher Vakoc. Some may even change to escape cancer treatment. Recent ...

In the 21st century, as global trade expands and cargo volumes surge, ports face mounting pressure to operate efficiently. A key challenge lies in accurately predicting vessel turnaround time (VTT)—the period between a ship’s arrival and departure—which directly influences scheduling, congestion management, and energy use. Traditionally, forecasting methods have relied on static factors, such as vessel specifications or container volumes, which fail to capture the highly dynamic ...

Scientists have engineered a nanowire platform that mimics brain tissue to study astrocytes, the star-shaped cells critical for brain health, for the first time in their natural state. Astrocytes are the brain’s most abundent and mysterious cells, responsible for regulating communication between neurons and helping to maintain the blood-brain barrier. They are also highly dynamic shape-shifters, someething they do not do on typical petri dishes, leaving major gaps in our understanding of how they ...

**EMBARGOED FOR RELEASE UNTIL NOV. 24 AT 5 A.M. ET** An experimental cancer vaccine developed at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy has shown early promise in a phase I clinical trial for a rare form of liver cancer that primarily affects children and young adults. The trial, led by investigators at Johns Hopkins and St. Jude Children’s Research Hospital, was supported by the National Cancer Institute and the Fibrolamellar Cancer Foundation. In the study, 75% of participants (nine patients) with fibrolamellar carcinoma (FLC) experienced disease control, including stable disease or measurable immune responses. ...

A major genetic risk factor for delirium has been identified in a landmark study that analysed the DNA of more than one million people worldwide. The study found that APOE, a gene already well known for its role in Alzheimer’s disease, also increases a person’s risk of developing delirium – a common medical condition characterised by a state of sudden mental confusion. Experts say this effect cannot be explained solely by the gene’s link to dementia, suggesting it also plays a distinctive, direct role in delirium. The ...

Humans have long wondered when and how we begin to form thoughts. Are we born with a pre-configured brain, or do thought patterns only begin to emerge in response to our sensory experiences of the world around us? Now, science is getting closer to answering the questions philosophers have pondered for centuries.  Researchers at the University of California, Santa Cruz, are using tiny models of human brain tissue, called organoids, to study the earliest moments of electrical activity in the brain. A new study in Nature Neuroscience finds that the earliest firings of the brain ...

Researchers have successfully grown platinum crystals in liquid metal, using a powerful X-ray technique giving rare insight into how these delicate crystals form and grow. More than a beautiful curiosity, liquid metal-grown crystals could be the key to creating new materials. They are potentially a vital ingredient in new technology being developed to extract hydrogen from water and in quantum computing applications.   Published in Nature Communications, the University of Sydney led team used metallic crystals to build an electrode that can efficiently produce hydrogen from water. Liquid metals like Gallium are curious elements. They shimmer on the surface like solid metals ...

When a wild orangutan leaves its mother after spending many years by her side, it has a mental catalog of almost 250 edible plants and animals, and the knowledge of how to acquire and process them. A new study in Nature Human Behaviour reveals that no lone orangutan could build this encyclopedic knowledge through trial and error. Instead, this knowledge forms a “culturally-dependent repertoire”— a diverse set of knowledge that is only attainable through years of watching and exploring alongside others. As humans, ...

Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor. Scientists have analysed lavas drilled from deep under the South Atlantic Ocean to understand how much CO2 is captured within the rocks due to reactions between the rocks and ocean. The research, led by the University of Southampton, found that piles of lava rubble, formed due to erosion of seafloor mountains, form geological sponges for CO2. It’s the first time the role of lava rubble as carbon sponges ...

Research led by polar scientists from Northumbria University has revealed new hope in natural environmental systems found in East Antarctica which could help mitigate the overall rise of carbon dioxide in the atmosphere over long timescales. As Antarctica's ice sheets thin due to climate change, newly exposed mountain peaks could significantly increase the supply of vital nutrients to the Southern Ocean which surrounds the continent, potentially enhancing its ability to absorb atmospheric carbon dioxide, according to the research published in Nature Communications. A team of scientists with expertise in oceanography, ice sheet modelling and geochemistry contributed to the study ...

Volcanic bubbles help foretell the fate of coral in more acidic seas By 2100 Australian and global coral reef communities will be slow to recover, less complex, and dominated by fleshy algae, as high carbon dioxide changes ocean chemistry. An international study published today in Communications Biology has used unique coral reefs in Papua New Guinea to determine the likely impact of ocean acidification on coral reefs in the face of climate change. Oceans are becoming more acidic as they absorb carbon dioxide from the atmosphere, and that acid will dissolve coral limestone. But it’s hard to predict what ...

Rutgers neuroscientist Peng Jiang was visiting his hometown of Qianshan, a city in China’s Anhui province, when a neighbor came to his parents’ house with a story that would stay with him. The man’s mother had been diagnosed with Alzheimer’s disease in her early 60s. After nearly a decade of decline, she no longer recognized her own son. One morning, she looked at him and asked gently, “How is your mother doing? Is she well?” As the neighbor recounted the moment, he broke into tears. He told Jiang that Alzheimer’s runs in his family and that he fears his own children may one day watch him fade the way he watched his mother’s memory vanish. That ...

The drug dexamethasone supplements cancer treatments to alleviate side effects of chemotherapy such as nausea or inflammation. Researchers at the University of Basel, Switzerland, have now discovered that it also fights metastases in certain types of breast cancer. The active substance dexamethasone is a synthetic signaling substance with a similar effect to the body’s own stress hormone cortisol. A research group at the University of Basel has found evidence that this drug, which has been in use for a long time, could have a new, additional effect in certain treatment-resistant ...

The same technology used in COVID-19 vaccines could help prevent muscle damage from snakebites, according to a new study published in Trends in Biotechnology today [24 November].  Scientists from the University of Reading and the Technical University of Denmark tested whether mRNA technology could be used to protect against the damage caused by the venom of the Bothrops asper snake, found in Central and South America. This snake's venom destroys muscle tissue, often leaving victims with permanent disabilities even after receiving standard treatment.  The research team wrapped specific mRNA molecules in ...

New research reveals that certain social determinants of health—such as socioeconomic status, household characteristics, and racial/ethnic minority status—have significant effects on rural–urban disparities in colorectal cancer mortality rates. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. Using 1999–2020 colorectal cancer mortality data from the Centers for Disease Control and Prevention pertaining to all US counties, investigators assessed how different components of the Social Vulnerability Index might affect differences in colorectal ...

There’s always a touch of melancholy when a chapter that has absorbed years of work comes to an end. In the case of the Atacama Cosmology Telescope (ACT), those years amount to nearly twenty — and now the telescope has completed its mission. Yet some endings are also important beginnings, opening new paths for the entire scientific community. The three papers just published in the Journal of Cosmology and Astroparticle Physics (JCAP) by the ACT Collaboration describe and contextualize in detail the sixth and final major ACT data release — perhaps the most ...
