What your genes can, and cannot, tell us about your personality

A meta-analysis of 46 cohorts involving 611,037 to 1.14 million participants identified 1,260 lead genetic variants associated with the Big Five personality traits, including 824 in previously unlinked genomic regions. The associations were broadly consistent across cohorts and measurement contexts, while polygenic analyses linked personality-related genetics to health, behavior, psychopathology, and life outcomes, although effects were modest and could not predict individual behavior.

Muscle matters: Simple scan could predict heart surgery risks

Around one in four heart surgery patients develop serious lung complications – but a new Adelaide-led study is testing a simple bedside scan that could predict who is most at risk before symptoms appear.

Nanoparticle flu vaccine design could pave way for broader protection

Influenza viruses constantly shapeshift to evade recognition by the immune system. This shapeshifting occurs in critical proteins like hemagglutinin (HA), which controls how the virus attaches to human cells before entering them.

Alcohol-related liver cancer deaths were falling. Then the trend reversed during the COVID-19 pandemic

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic decline to an increase during 2020–2023, particularly among women, although the researchers cautioned that the ecological analysis cannot establish that pandemic-related changes caused the reversal.

Penn Medicine tests FLASH proton therapy for cancer patients

A new form of proton therapy-designed to deliver cancer-killing radiation therapy in less than a second, through fewer total sessions, with potentially less risk of damaging side effects-is now being tested in a Phase I clinical trial at the Abramson Cancer Center of the University of Pennsylvania.

Antiviral COVID-19 drug shows no benefit for Long COVID

Results from a clinical trial funded by the National Institutes of Health (NIH) and published today in the journal Lancet Infectious Diseases show that the antiviral drug, PAXLOVID, commonly prescribed to treat acute COVID-19, does not have an impact on Long COVID symptoms when compared to placebo.

UCSF scientists build largest molecular interaction map for autism

For more than two decades, researchers have identified hundreds of genes that increase the risk of autism spectrum disorder (ASD).

Study reveals how SGLT2 inhibitors improve failing heart function

Researchers have discovered that SGLT2 inhibitors, a class of drugs originally developed to treat diabetes and now widely used for heart failure, work by activating a key enzyme that helps heart cells produce and use energy more efficiently.

Alliance releases new film highlighting the critical role of clinical trials

The Alliance for Clinical Trials in Oncology has released a film highlighting the critical role of participant involvement in advancing cancer research and improving care.

Anti-immigrant policies linked to rising HIV cases among Hispanic populations

Following the Trump administration's 2018 announcement of changes to the public charge rule that would penalize immigrants for using public benefit programs, antisanctuary counties in the US saw a 16.8-percent increase in HIV cases among Hispanic populations, compared to baseline counties.

Nigerian COVID-19 response highlights cultural trust in ethnopharmacology

During COVID-19, ethnopharmacology became prominent in Nigeria due to affordability, accessibility, and cultural trust, but evidence for safety and efficacy remains limited.

Visual storytelling transforms scientific evidence into meaningful public health action

Even as the scientific community has reached broad consensus that infectious pathogens, such as viruses, can spread through airborne transmission in virus-laden aerosols, one fundamental challenge remains.

Survey provides a comprehensive snapshot of youth mental health and drug use in Ontario

Findings from the 2025 Ontario Student Drug Use and Health Survey (OSDUHS) released today by the Centre for Addiction and Mental Health (CAMH) suggest that Ontario middle and high school students have rebounded from the heightened mental health challenges seen during and immediately following the COVID-19 pandemic.

Study highlights strengths and barriers of remote heart failure care

Interviews with patients hospitalized for heart failure, caregivers, providers, and organizational leaders highlighted several strengths of Mighty Heart (a major clinical trial examining the effectiveness of in home and telehealth-enabled visits from paramedics) that may support its adoption and implementation across health systems, a Columbia Nursing-led study finds.

Study links past COVID infection to stronger breathing response after brief arousals from sleep

COVID-19 can leave behind fatigue, breathing difficulties and neurological symptoms that persist long after the initial infection.

AI predicts vaccine response based on pre-existing antibody patterns

Vaccines protect most people from serious illness, but the strength of that protection can vary considerably from one person to another. A new study led by Arizona State University helps us understand why.

First 24 hours shape the body's antiviral defense response

Age, genetics and lifestyle are known to influence how people respond to viral infections. Scientists also know that differences in immune response play an important role, but exactly how these factors shape the course of an infection has remained unclear.

Lower-calorie meals look cheaper, but there’s a catch in the price

Analysis of 7,392 menu items from 200 large restaurant chains found that lower-calorie options on two major UK food delivery platforms carried a substantially higher cost per 100 kcal than higher-calorie items. The findings suggest that per-calorie pricing may create financial disincentives for choosing lower-calorie foods, with potential implications for diet-related health inequalities.

Novel norovirus vaccine approach may be adaptable for other RNA viruses

Every RNA virus — from stomach bugs and influenza to chickenpox and the common cold — has its own story to tell, with a unique combination of symptoms, rates of transmission, duration, and chemical blueprint.

New project builds AI infrastructure for healthcare crisis management

Which hospitals could become unavailable in the event of a natural disaster? How many intensive care beds are available, and what medicines are in stock? In the future, answers to questions like these should be available and updated more quickly.
