Higher levels of wellbeing may help reduce the risk of memory loss in middle age, suggests new research, which tracked more than 10,000 over 50-year-olds across a 16-year span. Findings that are published today, in the peer-reviewed journal Aging & Mental Health, found those who said they had higher wellbeing were more likely to subsequently have better scores on memory tests. These people – all of whom were determined as having ‘healthy brains’ – also reported a greater sense of control, independence, and freedom to make choices.   This ...

Embargoed until 19 June 2025, 00:01 (CEST)    19 June 2025, Bonn – The central estimate of the remaining carbon budget for 1.5°C is 130 billion tonnes of carbon dioxide (CO2) (from the beginning of 2025). This would be exhausted in a little more than three years at current levels of CO2 emissions, according to the latest Indicators of Global Climate Change study published today in the journal Earth System Science Data, and the budget for 1.6°C or 1.7°C could be exceeded within nine years.     Prof. Piers Forster, Director of the Priestley Centre for Climate Futures at the University of Leeds and lead ...

The anti-aging drug Rapamycin has the same life-extending effect as eating less, according to new research from the University of East Anglia and University of Glasgow. Dietary restriction has long been considered one of the most reliable methods for increasing lifespan across species. But if fasting for hours sounds unpleasant, science may suggest another route to achieving a longer and healthier life. A new study published today reveals compelling evidence that Rapamycin, a compound originally developed as an immunosuppressant, offers comparable life-extending benefits in eight species of vertebrates, not including humans. Co-lead researcher Dr Zahida Sultanova, from UEA’s ...

Brain networks responsible for sensing, understanding, and responding emotionally to pain develop at different rates in infants, with the conscious understanding of pain not fully developed until after birth, finds a new study led by UCL (University College London) researchers. The authors of the study, published in the journal Pain, investigated how different types of pain processing develop very early on, by scanning the brains of infants born prematurely. Lead author Professor Lorenzo Fabrizi (UCL Neuroscience, Physiology & Pharmacology) said: “Pain is a complex ...

From that meeting, a new white paper, published recently in Chemical Senses, ...

LA JOLLA, CA—In the quest to develop an effective HIV vaccine, scientists from Scripps Research have made a significant leap forward. They found that a two-part delivery strategy can train the immune system to produce a stronger response to HIV, offering new hope in the fight against one of the world’s most elusive viruses. The approach, described in Science Translational Medicine on June 18, 2025, used a mouse model to test two types of adjuvants: immune-boosting molecules that improve vaccine response. One of the adjuvants helped the HIV protein persist longer in the body, and another amplified immune activation. ...

Would you rather have 10 cents in your pocket or a 1-in-10,000 shot at $1,000? Many people would choose the latter, and that could be the key to getting people to recycle more, a new University of British Columbia psychology study has found. The researchers tested the idea of offering people who return used bottles a tiny chance to win a big cash prize, instead of the typical 10-cent deposit return. The result was that people recycled 47 per cent more bottles. “This small change in how we reward recycling made a big difference. People were more excited, more engaged, and they brought in more bottles,” ...

The state of Texas awarded UTHealth Houston School of Public Health $5 million over two years for early detection and research, led by principal investigator Jooyeon Hwang, PhD, associate professor in the Department of Environmental and Occupational Health Sciences, on cancer risk among firefighters in Texas.  Repeated exposure to harmful chemicals in fire smoke, common in the work of firefighters, can cause long-term chronic health problems including cancer, according to previous work by Hwang. Firefighters have a 9% higher risk ...

EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, JUNE 18, 2025 What is a brain age gap, and how may it affect thinking and memory skills? MINNEAPOLIS — The difference between the brain’s predicted age and actual chronological age, called a brain age gap, may influence the relationship between cognitive impairment risk factors, like high blood pressure and diabetes, and a person’s cognitive performance, also known as thinking and memory skills, according to a study published June 18, 2025, in Neurology®, the medical journal of the American Academy of Neurology. Advances in neuroimaging have led to the development ...

EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, JUNE 18, 2025 Highlights: Having at least one social factor affecting health, like food insecurity or not having a safe place to live or enough social support, was linked to worse recovery after stroke. Food insecurity, the most common factor, was linked to having trouble moving, needing a breathing or feeding tube or hospice care. Even though they had worse recovery rates, people with these factors had better survival rates up to one year after stroke compared to those without negative social factors. This unexpected finding suggests worse recovery does not necessarily translate to poorer ...

Researchers have found a promising new method for gene therapy. They successfully restarted inactive genes by bringing them closer to genetic switches on the DNA called enhancers. The intermediate piece of DNA was cut out using CRISPR-Cas9 technology. This strategy opens up new possibilities for treating genetic diseases. The team specifically shows the technology’s potential for the treatment of sickle cell disease and beta-thalassemia, two genetic blood diseases. In these conditions, a faulty gene could potentially be compensated by reactivating a helpful but normally inactive one. This ‘delete-to-recruit’ ...

As experts dedicated to providing patients with compassionate, evidence-based care every day, we are disappointed in the United States vs. Skrmetti decision, which increases the likelihood that other states will limit or eliminate families’ and patients’ ability to access medical care. As doctors, nurse practitioners, and nurses, we believe that every patient is different. Decisions about medical care must be based on individualized assessments by qualified professionals in consultation with the patient and their parents or legal guardians and guided by well-designed medical evidence. This Supreme Court decision strips patients and families of the choice ...

Knee osteoarthritis (KOA) is a common and often debilitating condition that affects millions of older adults, causing pain and stiffening of the knee joint. Treatment often includes anti-inflammatory drugs, which are linked to gastrointestinal and cardiovascular adverse events. In ...

QUT robotics researchers have developed a new robot navigation system that mimics neural processes of the human brain and uses less than 10 per cent of the energy required by traditional systems. In a study published in the journal Science Robotics, the researchers detail a new system which they call LENS – Locational Encoding with Neuromorphic Systems. LENS uses brain-inspired computing to set a new, low-energy benchmark for robotic place recognition. The research, conducted by first author neuroscientist Dr Adam Hines along with Professor Michael Milford and Dr Tobias Fischer, all from the QUT Centre of Robotics and the QUT School of Electrical Engineering and Robotics, uses ...

A new study from scientists at the University of North Carolina at Chapel Hill reveals that the cells shaping our organs may be far more mobile and coordinated than once believed.  Using fruit flies as a model, researchers discovered that future muscle cells crawl across the surface of the developing testis and actively sculpt it into its final form. These dynamic cells don’t work alone, they coordinate their movements using a communication system previously typically associated with brain development.  “While most organs are thought to be shaped by static, brick-like cells, our study highlights the powerful role of dynamic, migrating cells — and how ...

Summary Excitons--bound pairs of electrons and holes created by light--are key to the optoelectronic behavior of carbon nanotubes (CNTs). However, because excitons are confined to extremely small regions and exist for only fleeting moments, it has been extremely challenging to directly observe their behavior using conventional measurement techniques. In this study, we overcame that challenge by using an ultrafast infrared near-field optical microscope that focuses femtosecond infrared laser pulses down to the nanoscale. This advanced approach allowed us to visualize where excitons ...

A new paper from Columbia University Mailman School of Public Health, Butler Columbia Aging Center, and Columbia Irving Medical Center introduces a scientific framework for understanding the biological foundation of health—what the researchers term Intrinsic Health. Published in Science Advances, the study lays the groundwork for measuring and promoting health itself, rather than merely treating disease. Titled “Intrinsic Health as a Foundation for a Science of Health,” the paper defines intrinsic health as a field-like state that supports the body’s ability to maintain internal balance across dynamic biological ...

Vance Holliday jumped at the invitation to go do geology at New Mexico's White Sands. The landscape, just west of Alamogordo, looks surreal – endless, rolling dunes of fine beige gypsum, left behind by ancient seas. It's one of the most unique geologic features in the world. But a national park protects much of the area's natural resources, and the U.S. Army uses an adjacent swath as a missile range, making research at White Sands impossible much of the time. So it was an easy call for Holliday, a University of Arizona archaeologist and geologist, to accept an invitation in 2012 ...

The gut microbiome, a vast assortment of bacteria and other microorganisms that inhabit our digestive system, plays a critical role in converting food into energy. Many of these microbes follow rhythmic cycles of activity throughout the day. However, high-fat diets and other factors can disrupt these rhythms and contribute to metabolic disease. A new study by researchers at University of California San Diego and their colleagues used time-restricted feeding (TRF), an intervention that limits dietary intake to a short time window each day, to restore microbial rhythms in mice fed a high-fat diet. By analyzing ...

NEW YORK, NY (June 18, 2025)--Addictive use of social media, video games, or mobile phones—but not total screen time—is associated with worse mental health among preteens, a new study by researchers at Columbia and Cornell universities has found.   The study, published June 18 in JAMA, examined the social media use of nearly 4,300 children, starting at age 8, and how use changed over the next four years.   Addictive use of screens—excessive use that interfered with schoolwork, home responsibilities, or other activities—was ...

Kyoto, Japan -- Sea cucumbers spend their lives prowling the ocean floor, scavenging for food and generally minding their own business. We can see snails leading similar lives, slimy but not bothering anyone. Yet some species of tiny sea snails are a bother: they are common parasites of sea cucumbers. Extensive taxonomic research has been conducted on these host-parasite interactions in Japan, where sea cucumbers are a seafood delicacy -- for humans. Despite these previous studies, however, local species richness still contains some unknowns. Parasites of the sea cucumber species Holothuria atra have been thoroughly investigated, but those of Holothuria leucospilota have not. This is ...
