Study reveals new information about how to prevent chronic inflammation from zombie-like cells that accumulate with age In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way. Certain factors can cause cells to abandon this characteristic and enter a zombie-like state known as senescence where they persist but no longer divide to make new cells. Our bodies can remove…

University of Arizona neuroscientists studying the brains of songbirds have found that aging alters the gene expressions that control the birds’ song. The finding could lead to earlier diagnoses and better treatments for human neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, which are known to hinder vocal production in their early stages. The study, published in the journal Neurobiology of Aging, found that networks of interacting genes, in a region of the bird’s brain involved with singing, dramatically…

A new type of antibody which stimulates the immune system to target cancer cells slows tumor growth, according to new research Antibody treatment which activates the patient’s own immune system against cancer, known as immunotherapy, is increasingly being investigated as an alternative for chemotherapy and radiotherapy. This is because it specifically targets the cancer cells, which reduces the side effects seen with more conventional therapies. Tumours, such as some breast and ovarian cancers, can express the marker HER2. HER2 is…

Study links genetics, vision and neural processing to mating behavior in Heliconius butterflies A simple neural change alters mating preferences in male butterflies, aiding rapid behavioral evolution, Nicholas VanKuren and Nathan Buerkle at the University of Chicago, US, and colleagues, report March 11th in the open-access journal PLOS Biology. Heliconius are a group of tropical butterflies known for their wide variety of wing patterns and colors, which act as a warning to predators. Because wing coloration is crucial for their…

As major changes continue for our planet’s climate, scientists are concerned about how plants will grow and adapt. Researchers in the MSU-DOE Plant Research Laboratory, or PRL, Sharkey lab are studying changes in plant metabolism that occur when plants are grown in high light, high CO2 (HLHC) conditions. They found that under these conditions, plants photosynthesize more, which can lead to larger plants, and potentially larger crop yields. However, there are tradeoffs; scientists also found that plants lose carbon under…

Understanding children’s subjective experiences through color As a child, did it ever occur to you that your perception of color differed from that of others? It’s quite common to have this thought, but it turns out that the human color experience may be more universal than we previously believed. In psychology and neuroscience, the relationship between subjective experience, such as how we perceive color, and physical brain activity has remained an unresolved problem. Furthermore, due to their limited language abilities,…

Scripps Research scientists created a stable form of carnosic acid, observing greater memory function and other disease improvements in mice. The herb rosemary has long been linked with memory: “There’s rosemary, that’s for remembrance,” says Ophelia in Shakespeare’s Hamlet. So it is fitting that researchers would study a compound found in rosemary and sage—carnosic acid—for its impact on Alzheimer’s disease. In the disease, which is the leading cause of dementia and the sixth leading cause of death in the US,…

Researchers from Osaka University find that in immune tissues, plasma cells that express certain proteins are more likely to migrate to the bone marrow, where they help create long-lasting antibody responses Vaccine effectiveness relies on creating a strong antibody response that can be reactivated to fight future infections. Now, researchers from Japan report that antibody-producing cells are destined for longevity from the moment they are born. In a recent study published in the Journal of Experimental Medicine, a multi-institutional research…

American Heart Association Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2025 – Oral Presentation 060 Research Highlights: Embargoed until 11 a.m. CT/12 p.m. ET, Sunday March 9, 2025 This news release contains updated information from the researcher that was not in the abstract and will be referenced in the oral presentation. Among postmenopausal women with a history of cancer, taking more daily steps and engaging in moderate-to-vigorous physical activity were both associated with a significantly reduced risk…

Novel study paints more accurate picture of extinct, gigantic shark The megalodon has long been imagined as an enormous great white shark, but new research suggests that perception is all wrong. The study finds the prehistoric hunter had a much longer body—closer in shape to a lemon shark or even a large whale. The study team, which included researchers from University of California, Riverside and across the globe, used a novel approach to estimate the shark’s total body length, moving…

National Poll: 2 in 5 parents wish the government was doing more to prevent a bird flu outbreak; 1 in 3 have taken action to protect their family against it With soaring egg prices and ongoing bird flu headlines, many parents are uncertain about the risks and facts surrounding the virus, a national poll suggests. Most parents say they don’t know if there have been cases of bird flu in their state, and less than half feel that they are…

Declining student performance tied to life skills gaps, not just pandemic The impact of the COVID-19 pandemic on student performance is well known, but four years after the pandemic, scores in college classes are not returning to their pre-pandemic levels.  A University of Mississippi study might point to an answer. In a study published in a special issue of the Educational Sciences journal, three Ole Miss researchers found that student performance scores started a downward trend following COVID-19. Dozens of…

Researchers at Rice University have uncovered a critical link between rising temperatures and declines in a species’ population, shedding new light on how global warming threatens natural ecosystems. The study, published in Ecology and led by Volker Rudolf, revealed that rising temperatures exacerbate competition within populations, ultimately leading to population crashes at higher temperatures. It offers one of the first clear experimental confirmations that rising temperatures alter the forces that control population dynamics in nature. “Our research provides an essential missing piece in…

Online threats, hatred and harassment have led people who feel discriminated against to create digital spaces where they can feel safe. According to a new thesis from the University of Gothenburg, these spaces are characterised by clear rules and constant maintenance and monitoring. Much of social life today takes place online. Unfortunately, the worst aspects of interpersonal relationships also appear in the digital world. A study of 51 countries revealed that 38% of women had personally experienced online harassment. Bullying…

Virginia Tech scientists at the Fralin Biomedical Research Institute at VTC found practicing episodic future thinking both reduced impulsivity and enhanced connectivity in key regions of the brain Learning to think more about specific events in the future appears to reduce impulsivity,  improve decision-making, and shows potential as a therapy for alcohol use disorder, a new Virginia Tech study found. The study, which involved 24 participants whose brains were scanned during both resting-state and task-based fMRI, showed brain connections were altered…

Researchers at the University of Gothenburg have discovered that what was previously thought to be a unique seaweed species of bladderwrack for the Baltic Sea is in fact a giant clone of common bladderwrack, perhaps the world’s largest clone overall.  The discovery has implications for predicting the future of seaweed in a changing ocean. In the brakish waters of the Baltic Sea, bladderwrack is the dominant seaweed species as it is one of the few seaweed species that can tolerate…
