Do you have lots of close friends – and work hard to keep it that way? If you’ve answered “yes”, you are probably nostalgic. People who are prone to nostalgia have more close friends and put more effort into maintaining their friendships and other relationships than less sentimental sorts. That’s the finding of a new study of almost 1,500 individuals in the U.S. and Europe, published in the peer-reviewed journal Cognition and Emotion. The finding is important because maintaining close relationships with others is essential ...

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 responsible for cancer growth and is the target of existing therapies, such as the most commonly used type of antibodies, IgG. However, this treatment ...

Royal Astronomical Society press release RAS PR 25/10 Embargoed until 00:01 on Thursday 13 March 2025 At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova explosions, a new study suggests. Researchers at Keele University say these super-powerful blasts – caused by the death of a massive star – may have previously stripped our planet's atmosphere of its ozone, sparked acid rain and exposed life to harmful ultraviolet radiation from the Sun. They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician ...

Over 1.2 million medical device adverse event reports were not submitted to the US Food and Drug Administration (FDA) within the deadline set by federal regulations, finds an analysis of recent data published by The BMJ today. Of these late reports, more than 400,000 were submitted more than six months after the manufacturer was notified of an adverse event. The researchers warn that late adverse event reporting may prevent early detection of patient safety concerns. Most medical devices in the US are approved on the condition that manufacturers report to the FDA when they learn that any of their devices have malfunctioned or may ...

Surgical adhesions — common, sometimes life-threatening complications that arise after open or laparoscopic abdominal surgery — can be prevented in mice and pigs by a gel impregnated with a molecule that blocks a key signaling pathway in the formation of scar tissue. The gel can be applied as a spray or a wash to the inside of the abdominal cavity immediately after surgery. Over a period of two weeks, the gel releases a small molecule, T-5224, that blocks the activation of adhesion-forming ...

Nickel’s role in the future of electric vehicle batteries is clear: It’s more abundant and easier to obtain than widely used cobalt, and its higher energy density means longer driving distances between charges. However, nickel is less stable than other materials with respect to cycle life, thermal stability, and safety. Researchers from The University of Texas at Austin and Argonne National Laboratory aim to change that with a new study that dives deep into nickel-based cathodes, one of the two electrodes that facilitate energy storage in batteries. "High-nickel cathodes ...

A study of over 32,000 people living in Tamil Nadu, India suggests scrub typhus infection may affect up to 10% of rural populations annually and is a leading yet under-recognised cause of hospitalisations for fever across India. The study, published in the New England Journal of Medicine, was conducted as part of a collaboration between the London School of Hygiene & Tropical Medicine (LSHTM) and the Christian Medical College Vellore, India. Scrub typhus is a potentially life-threatening infection caused by the bacterium Orientia tsutsugamushi, which belongs to the rickettsia family. It is spread to humans through the bite of infected larval mites or chiggers. Chiggers are found ...

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 ...

Spatial transcriptomics is a cutting-edge technique that characterizes gene expression within sections of tissue, such as heart, skin or liver tissue. These snapshots provide insights into how spatial organization affects cellular functions across the spectrum of biology and disease. Up to now, researchers conducting spatial transcriptomics have had to choose between two options based on their needs: genome-wide coverage or single-cell resolution. To solve this tradeoff, scientists at St. Jude Children’s Research Hospital and the University of ...

ITHACA, N.Y. -- In a scene toward the end of the 2006 film, “X-Men: The Last Stand,” a character claps and sends a shock wave that knocks out an opposing army. Sunny Jung, professor of biological and environmental engineering in the College of Agriculture and Life Sciences, was intrigued. “It made me curious about how the wave propagates when we clap our hands,” Jung said. Jung is senior author of a study, published March 11 in Physical Review Research, that elucidates the complex physical mechanisms and fluid dynamics involved in a handclap, with potential applications in bioacoustics ...

For those looking to climb the corporate ladder in the U.S., here’s an idea you might not have considered: debate training. According to a new research paper, people who learn the basics of debate are more likely to advance to leadership roles in U.S. organizations, compared to those who do not receive this training. One key reason is that being equipped with debate skills makes people more assertive in the workplace.  “Debate training can promote leadership emergence and advancement by fostering individuals’ assertiveness, which is a key, valued leadership characteristic in U.S. organizations,” says MIT Associate Professor Jackson Lu, one of the scholars ...

A new analysis reveals complex linkages among the United Nations’ (UN’s) 17 Sustainable Development Goals—which include such objectives as gender equality and quality education—and finds that no country is on track to meet all 17 goals by the target year of 2030.

In 2015, UN member countries adopted the Sustainable Development ...

Spinal cord injuries are life-altering, often leaving individuals with severe mobility impairments. While rehabilitation robotics—devices that guide movement during therapy—have improved training for those with spinal cord injuries, their effectiveness remains limited. Without active muscle engagement, robotic-assisted movement alone does not sufficiently retrain the nervous system. A team at .NeuroRestore, led by Grégoire Courtine and Jocelyne Bloch, has now developed a system that seemlessly integrates an implanted spinal cord neuroprosthesis with rehabilitation robotics. The researchers’ device delivers well-timed electrical pulses to stimulate ...

A new study reveals that a region in China's Turpan-Hami Basin served as a refugium, or "Life oasis" for terrestrial plants during the end-Permian mass extinction, the most severe biological crisis since the Cambrian period. The research, published in Science Advances, challenges the widely held view that terrestrial ecosystems suffered the same catastrophic losses as marine environments during this period. The discovery, led by Prof. LIU Feng from the Nanjing Institute of Geology and Palaeontology (NIGPAS) of the Chinese Academy of Sciences, provides the first conclusive fossil evidence ...

A new study from the University of Nottingham has revealed that poor sleep quality may increase susceptibility to conspiracy beliefs, with depression likely playing a key role in this relationship. Experts from the University’s School of Psychology examined the link between sleep quality and conspiracy beliefs in two studies involving over 1,000 participants. Their findings, published in the Journal of Health Psychology, indicate that individuals with poorer sleep quality over the past month were more likely to endorse conspiracy theories, particularly after exposure to conspiratorial content. Conspiracy theories claim that powerful, secretive ...
