Bacteria aren’t just mindless microbes. New research from the Hebrew University of Jerusalem reveals that single bacterial cells can carry a “memory” of their past environments—passing it down through generations—before eventually forgetting. Using a new technique called Microcolony-seq, scientists uncovered hidden subpopulations inside infections, each with different survival strategies. The finding could explain why antibiotics and vaccines sometimes fail—and may point the way toward more precise treatments. [Hebrew University of Jerusalem]– ...

An international team of researchers has conducted the most comprehensive global-to-local analysis to date on long COVID risk, using disability data from the height of the pandemic to identify vulnerable populations. Drawing on the Global Burden of Disease (GBD) 2021 framework, the study examined years lived with disability (YLDs) caused by COVID-19 across 920 locations during 2020 and 2021. The results reveal that YLDs may serve as an early indicator of long COVID risk—particularly in areas where post-COVID conditions remain underreported. “Disability-related data may serve as an early warning ...

Lung cancer is the leading cause of cancer-related mortality worldwide, with significant heterogeneity among its major histological subtypes: adenocarcinoma (ADC), squamous cell carcinoma (SCC), and small cell lung cancer (SCLC). These subtypes differ not only in clinical behavior and treatment response but also in their metabolic profiles. Metabolomics has emerged as a powerful tool to decipher cancer metabolic reprogramming, offering new insights into subtype-specific metabolic alterations. This review synthesizes recent advances in metabolomic research across lung cancer subtypes, highlighting the roles of lipid, amino acid, ...

Within the next few years, doctors may be able to spot signs of Alzheimer’s disease and other dementias using routine eye exams well before symptoms appear, a new study suggests. The research, recently published in Alzheimer’s & Dementia, links abnormal changes in the tiny blood vessels of the retinas of mice with a common genetic mutation known to increase Alzheimer’s disease risk. The findings build on previous work from the same group at The Jackson Laboratory (JAX), which found similar vascular changes in mice’s brains and linked abnormalities in specific retinal cells to early ...

INDIANAPOLIS -- In a groundbreaking study, research scientists from the Indiana University School of Medicine and Regenstrief Institute found that individuals with a parent who died from liver disease face more than double the risk of developing alcohol-associated hepatitis, one of the deadliest forms of alcohol-related liver disease, compared with similar heavy drinkers without that family history. Researchers investigated the impact of parental liver disease mortality on both the development and outcomes of alcohol-associated hepatitis in adult children. In the U.S., nearly 20,000 people die from alcoholic liver disease each year, according to the National Council on Alcoholism and Drug ...

Emotions are complicated things. Researchers have found some differences between men and women, but basically the same factors play the biggest part in whether we feel good about ourselves. “We investigated differences between the sexes and the relationships between factors that influence participants’ motivation and well-being,” said Professor Hermundur Sigmundsson at the Norwegian University of Science and Technology (NTNU’s) Department of Psychology. He has spent many years studying what it takes for people to achieve their goals, and in this ...

Miami (August 26, 2025) – People with schizophrenia are more likely to develop chronic obstructive pulmonary disease (COPD), suggesting a possible syndemic relationship between the two diseases, in addition to people not seeking appropriate medical care. A new article examining the link between COPD and schizophrenia appears in the July 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open access journal. COPD encompasses conditions including emphysema and ...

Human men are typically more aggressive than human women, a finding supported by reams of research. But surveys of  4,136 individuals in 24 countries reveal an exception to the trend: aggression in sibling relationships. Douglas T. Kenrick and Michael E.W. Warnum, along with a team of 49 colleagues, asked participants how often they had acted aggressively towards a sister, a brother, a female friend, a male friend, a female acquaintance, or a male acquaintance—both when they were children and when they were adults.  Aggressive actions included both direct aggression, such as hitting/slapping ...

Chemicals used to replace bisphenol A (BPA) in food packaging can trigger potentially harmful effects in human ovarian cells, according to McGill University researchers. A new study examined several chemicals commonly used in price stickers on packaged meat, fish, cheese and produce found early signs of potential toxicity. The findings, published in the journal Toxicological Sciences, raise concerns about the safety of BPA-free packaging and whether current regulations go far enough to protect consumers. BPA substitutes disrupt gene expression The research began with the 2023 discovery by Stéphane Bayen, Associate Professor in McGill’s ...

Researchers explore the human tendency to look to the past to predict the future—even when people rationally know outcomes are completely random. A fair coin flip is the prototypically random-outcome event. Russell Roberts and colleagues asked 12,000 people to predict coin flip outcomes in a sequence of five fair coin tosses—some in person, some online. With such a large number of participants, they were able to analyze subsets of people who—by chance—made a series of successful or unsuccessful guesses without any deception or manipulation of the ...

Different countries have different cultures, and social scientists have developed theories about which values are most important in differentiating the world’s cultures. Abhishek Sheetal and colleagues used the power of machine learning to identify the crucial distinguishing characteristics of the world’s national cultures in a theory-blind manner. The authors trained a neural network to predict an individual’s country of origin from their attitudes, values, and beliefs, as measured by the World Values Survey, a global study that probes everything from religious beliefs ...

Catastrophes, by definition, are devastating, but they can often be catalysts for lasting, positive change – and if people can adopt that perspective, they may see some real benefits, a Stanford-led study suggests. In a randomized, controlled trial, a one-hour intervention was given to a group of adults designed to shift their mindset, or core beliefs and assumptions, about having lived through a catastrophe like the COVID-19 pandemic, with the goal of seeing growth opportunities in the experience. Those who received the intervention showed lower levels of depression three months later compared to a control group. Blood tests also revealed lower ...

Longer thumbs mean bigger brains, scientists have found - revealing how human hands and minds evolved together.  Researchers studied 94 different primate species, including fossils and living animals, to understand how our ancestors developed their abilities. They found that species with relatively longer thumbs, which help with gripping small objects precisely, consistently had larger brains.  The research, published today (Tuesday, 26 August) in Communications Biology, provides the first direct evidence that manual dexterity and brain evolution are connected across the entire primate lineage, from lemurs to humans.   Humans and our extinct ...

Researchers have shown for the first time how hidden motions could control how granular materials such as soil and snow slip and slide, confirming a long-suspected hypothesis. The knowledge could help in understanding how landslides and avalanches work and even help the construction industry in the future. Scientists have found sneaky swirls and loops of movement in materials such as soil and snow could influence how materials move. The knowledge could be invaluable in understanding how avalanches and landslides on Earth and Mars speed up or slow ...

Volcanoes that blast gases high into the atmosphere not only change global temperatures but also influence flooding in unusual ways, Princeton researchers have found. In an August 26 article in the journal Nature Geoscience, the researchers reported that major eruptions create distinct patterns of flooding depending on the location of the volcano and the dispersal of its plume. The patterns mostly divide along the line of the equator. When a volcano’s plume is generally contained in one hemisphere, flooding decreases in that hemisphere and ...
