Research conducted by the National Cancer Research Centre (CNIO), published today in ‘Nature’, reveals a mechanism in mice that is triggered just minutes after acute liver damage occurs. This finding opens up avenues for future treatments of serious liver damage to include a diet enriched with the amino acid glutamate. Glutamate supplementation can promote liver regeneration and benefit patients in recovery following hepatectomy or awaiting a transplant, the authors write in ‘Nature’. Activating liver regeneration is key to treating diseases that involve severe liver damage, which are becoming increasingly frequent and are associated ...

The pleasure we get from eating junk food — the dopamine rush from crunching down on salty, greasy French fries and a luscious burger — is often blamed as the cause of overeating and rising obesity rates in our society. But a new study by scientists at the University of California, Berkeley, suggests that pleasure in eating, even eating junk food, is key for maintaining a healthy weight in a society that abounds with cheap, high-fat food. Paradoxically, anecdotal evidence suggests that people with obesity may take less pleasure in eating than those of normal weight. Brain scans of obese individuals ...

CLEVELAND—The body’s cells respond to stress—toxins, mutations, starvation or other assaults—by pausing normal functions to focus on conserving energy, repairing damaged components and boosting defenses. If the stress is manageable, cells resume normal activity; if not, they self-destruct. Scientists have believed for decades this response happens as a linear chain of events: sensors in the cell “sound an alarm” and modify a key protein, which then changes a second protein that slows or shuts down the cell’s normal function. But in a new study published today in the journal Nature, researchers at Case Western Reserve University have discovered a ...

Oxford Chemistry researchers have developed a method to destroy fluorine-containing PFAS (sometimes labelled ‘forever chemicals’) while recovering their fluorine content for future use. The results have been published today (26 March 2025) in Nature. PFAS – which stands for poly- and perfluoroalkylated substances – have been produced in large ...

The last time a new class of antibiotics reached the market was nearly three decades ago — but that could soon change, thanks to a discovery by researchers at McMaster University. A team led by renowned researcher Gerry Wright has identified a strong candidate to challenge even some of the most drug-resistant bacteria on the planet: a new molecule called lariocidin. The findings were published in the journal Nature on March 26, 2025. The discovery of the all-new class of antibiotics responds to a critical need for new antimicrobial ...

Humans are having a highly detrimental impact on biodiversity worldwide. Not only is the number of species declining, but the composition of species communities is also changing. These are the findings of a study by Eawag and the University of Zurich published in the scientific journal Nature. It is one of the largest studies ever conducted on this topic. Biological diversity is under threat. More and more plant and animal species are disappearing worldwide, and humans are responsible. Until now, however, there has been no synthesis of the extent of human intervention in nature and whether the effects can be found everywhere in the world ...

Compared to sugar, consuming sucralose—a widely used sugar substitute—increases activity in the hypothalamus, a brain region that regulates appetite and body weight, according to a new USC study. Sucralose also changes how the hypothalamus communicates with other brain regions, including those involved in motivation. The study was just published in the journal Nature Metabolism. About 40% of Americans regularly consume sugar substitutes, usually as a way to reduce calories or sugar intake. “But are these substances actually helpful for regulating ...

In a new paper in Nature, a team of researchers from JPMorganChase, Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory and The University of Texas at Austin describe a milestone in the field of quantum computing, with potential applications in cryptography, fairness and privacy. Using a 56-qubit quantum computer, they have for the first time experimentally demonstrated certified randomness, a way of generating random numbers from a quantum computer and then using a classical supercomputer to prove they are truly random and freshly generated. This could pave the way towards the use of quantum computers for a practical task unattainable through ...

A small molecule shaped like a lasso may be a powerful tool in the fight against infectious diseases, according to a new study in Nature co-authored by University of Illinois Chicago researchers.  Lariocidin, a peptide made by bacteria living in soil, was effective against several different microbes responsible for deadly infections. UIC researchers working with collaborators at McMaster University in Canada determined how the new antibiotic works and why the drug evades bacterial resistance.   “The holy grail in the field is to find an antibiotic that binds to a new site target, has a novel mechanism of action and has ...

INDIANAPOLIS – Two recent studies by researchers from Regenstrief Institute and the Indiana University School of Medicine explore the effect of the pandemic on colorectal cancer screening tests and diagnostic colonoscopies in Central Indiana. The findings of temporary disruption to the former and minimal impact on the latter are similar to findings across the U.S., contributing to the compendium of knowledge on preventive health uptake and subsequent treatment in various populations during the pandemic. One study, published in PLoS One, examines both non-invasive and colonoscopy screening trends during the pandemic. The other study, ...

A new study by researchers at Peking University and the Chinese PLA General Hospital has found that multimorbidity—living with multiple chronic diseases—is closely associated with worsening fall conditions and mortality among middle-aged and older adults in China. The findings, published in Health Data Science, identify a distinct group at especially high risk: individuals with both cardiovascular and musculoskeletal conditions, dubbed the “osteo-cardiovascular fallers.”   Falls are a major cause of injury and death in older populations globally, particularly ...

Without clear and effective biological tests for autism based on genes, brain or blood measurements, diagnosis today still largely depends on clinical assessment. The standard way of doing this is by observing how the individual fits the criteria for autism listed in gold standard manuals like the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). These criteria are divided into two categories: one for restricted or repetitive behaviours, actions, or activities, and another for differences in social communication and interaction. In the end, however, it is the clinician, relying on years of ...

People with autism are typically diagnosed by clinical observation and assessment. To deconstruct the clinical decision process, which is often subjective and difficult to describe, researchers used a large language model (LLM) to synthesize the behaviors and observations that are most indicative of an autism diagnosis. Their results, publishing in the Cell Press journal Cell, show that repetitive behaviors, special interests, and perception-based behaviors are most associated with an autism diagnosis. These findings have potential to improve diagnostic guidelines ...

In diagnosing autism – the developmental variant that affects around 80 million people worldwide – medical practitioners today put too much emphasis on a child's lack of sociability and not enough on their interests and how they naturally behave spontaneously with objects. And so, to be more accurate in their assessments, health authorities should start tapping the vast analytic powers of artificial intelligence, combined with the experience of clinicians, and come up with better diagnostic criteria. That's ...

About The Study: In this cohort study of 3.7 million individuals, living alone with depression or anxiety was associated with an increased risk of suicide, particularly among middle-aged individuals and men.

When someone has a stroke, it can accelerate the loss of cognitive ability over the coming years. Stroke survivors who have attended some level of higher education may face even steeper mental declines, according to a study led by Michigan Medicine. In an analysis of cognitive outcomes for more than 2,000 patients seen for stroke between 1971 and 2019, college graduates performed better on initial post-stroke examinations of global cognition, a measure of overall cognitive ability that includes mental functions like memory, attention and processing speed. However, ...

Los Angeles (February –, 2025)—Evolving roughly 27 different times in the long history of fish, bioluminescence—the biological production of light—is one of the flashier survival tools used for luring prey, communication, and recognizing potential mates among various species. In a new study published in Ichthyological Research, an international team of researchers studied the organs that produce light in Vinciguerria mabahiss, a rare species of fish from the Red Sea. This paper marks the first-ever close examination of these organs, providing key information on their structure ...

Getting zapped with millions of volts of electricity may not sound like a healthy activity, but for some trees, it is. A new study, published in New Phytologist, reports that some tropical tree species are not only able to tolerate lightning strikes, but benefit from them. The trees may have even evolved to act as lightning rods. The research was led by Evan Gora, a forest ecologist at Cary Institute of Ecosystem Studies. Gora studies how lightning impacts biodiversity and carbon storage in Panama’s tropical forests.  Lightning kills hundreds of millions of trees per year. But in 2015, while working in Panama, Gora and his colleagues came across ...

Taking a person’s life is not automatically harmful to a soldier’s mental well-being if the circumstances justified it, according to a study of more than 14,600 soldiers. “Killing another person does not in itself seem to be something that goes against human nature, and it doesn’t necessarily harm the mental health of the person who does it,” said Andreas Espetvedt Nordstrand, a Norwegian clinical psychologist. Commander Nordstrand is the head of research and development at the Institute of Military Psychiatry, Norwegian Armed Forces – Joint ...

The National Institute of Standards and Technology (NIST) has selected Florida Atlantic University’s Hamming Quasi-Cyclic (HQC) for standardization in its Post-Quantum Cryptography (PQC) project.

LOS ANGELES — Researchers at City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the U.S. with its National Medical Center named top 5 in the nation for cancer by U.S. News & World Report, have found that cell mutations are necessary but not always sufficient for tumors to form. Instead, they suggest that additional risk factors that promote tumor growth, like chronic inflammation, are a key trigger for tumor formation. The study findings, published this month in Cancer Discovery, answer a question that scientists have long asked: Are cell mutations alone ...
