Vaccine against Zika virus shows promising results in tests with mice

A study recently published in the European Journal of Preventive Cardiology shows that cardiovascular health is affected not only by the total amount of physical activity, but also by how often you move during the day. Among the oldest participants, the study found that several short walks per day had a protective effect, regardless of pace. This correlation remained even when adjusted for total walking time.

How many times have you stared at a home COVID-19 test, waiting for the faint line that confirms an infection? Those home antigen tests often fail to detect a recent infection or one with no symptoms. A PCR test is more accurate, but it must be done by a medical lab and the results take days to deliver.

It is well established that stress can increase susceptibility to various neuropsychiatric disorders, such as depression and anxiety, which are highly prevalent worldwide and represent a significant economic burden and public health issue in our society. The World Health Organization estimated that in 2019, around 970 million people globally—1 in 8—suffered from a mental disorder.

National Football League (NFL) athletes who play wide receiver or tight end may have a higher risk of suffering an injury to their anterior cruciate ligament, or ACL, according to a new study from the University of Missouri School of Medicine. The research is published in The Journal of Knee Surgery.

A recent University of Michigan-led study finds that 10% of patients hospitalized with sepsis were previously healthy—and many of those who ultimately died did so because it was too late to intervene.

Researchers at Texas Biomedical Research Institute have developed a new, proof-of-concept vaccine to protect people from the bird flu strain currently circulating in the United States. The team, led by Professor Luis Martinez-Sobrido, Ph.D. and Staff Scientist Ahmed M. Elsayed, Ph.D., recently published initial results in npj Vaccines.

A research team led by Bristol and Cambridge universities has demonstrated that the polymer material used to make a new artificial heart valve is safe following a six-month test in sheep.

From "try yoga" to "start journaling," most mental health advice piles on extra tasks. Rarely does it tell you to stop doing something harmful.

It's a fact of life: Some people age better than others. Some ease into their 90s with mind and body intact, while others battle diabetes, Alzheimer's or mobility issues decades earlier. Some can withstand a bad fall or bout of the flu with ease, while others never leave the hospital again.

By revealing the molecular mechanisms behind the peacekeeping abilities of specialized immune cells, scientists are uncovering new pathways for treating autoimmune conditions and detecting diseases like cancer.

Multiple sclerosis (MS) has long been regarded as a disease with different subtypes such as "relapsing" or "progressive." An international study, published on August 20, 2025, in Nature Medicine under the leadership of the Medical Center—University of Freiburg and the University of Oxford, challenges this dogmatic model after analyzing the NO.MS cohort (study data from Novartis).

Memories of significant learning experiences—like the first time a driver gets a speeding ticket—are sharp, compared to the recollection of everyday events—like what someone ate for dinner two weeks ago. That's because the human brain is primed to learn from helpful associations.

Young people who are offered confidential and free access to prescription contraception methods are significantly more likely to use them, according to a new McMaster University study.

There is often a dramatic scene in crime shows where an eyewitness points to a suspect in a police lineup. This identification looks convincing on television, and it is also convincing in real-world investigations. But here's the problem: eyewitnesses can often be wrong. Their mistakes are a leading cause of wrongful convictions.

Portable air cleaners aimed at curbing indoor spread of infections are rarely tested for how well they protect people—and very few studies evaluate their potentially harmful effects. That's the upshot of a detailed review of nearly 700 studies that we co-authored in the journal Annals of Internal Medicine.

An international research team from Leibniz-FMP, the University of Oxford, and the University of Birmingham have developed a novel imaging approach to track how popular dual agonist drugs like tirzepatide interact with cells in the pancreas and brain. Published this week in Nature Metabolism, the findings could support the design of more effective treatments for diabetes and obesity.

New research from Dana-Farber Cancer Institute shows that a new class of drug results in cell death in cancers, such as small cell lung cancer, with a disabled quality control cell cycle checkpoint known as the G1/S checkpoint. The evidence gathered in the Oser Lab at Dana-Farber supports testing of the strategy in humans.

Cancer cells can break down the protective covers around nerves, causing nerve injury that triggers chronic inflammation, leading to immune exhaustion and eventual resistance to immunotherapy, according to new research from the University of Texas MD Anderson Cancer Center.
