Are ultramarathon runners really at increased risk of bowel cancer?

Breastfeeding offers many benefits, from emotional bonding to better nutrition and immune support. But for parents who need to pump and store breast milk, handling it safely is key.

Belgian scientists have uncovered new details about how the immune system responds to vaccines. Dendritic cells, which are key immune messengers that help kick-start the body's defenses, show specific responses to lipid nanoparticles. These findings, published in Cell Reports, could lead to safer and more effective vaccines.

Patients with intermediate stage primary liver cancer who received a vaccine of dendritic cells saw a longer time without tumor progression in response to standard treatment, according to a new study led by the University of Birmingham.

Lowering the activity of interleukin-6 (IL-6)—a key immune signal regulating inflammatory responses in the body—could reduce the risk of cardiovascular disease without making people more vulnerable to infections, according to new research from LMU's Institute for Stroke and Dementia Research and international collaborators.

Alexander Christensen's recent study probably won't rewrite 40 years of history in the field of psychology, but he hopes that his research team's quantitative approach to developing and evaluating personality structures triggers a discussion about how personality is defined and measured. Such discussion could hold broader implications for the field of personality psychology and potentially for classifications in psychopathology.

Chemicals used to replace bisphenol A (BPA) in food packaging can trigger potentially harmful effects in human ovarian cells, according to McGill University researchers.

After 140 years of vital, often invisible service, public health nurses (PHNs) deserve formal recognition as a distinct occupation, says a new study from Columbia University Mailman School of Public Health. The research argues that classifying PHNs under a unique federal occupational category would finally allow the U.S. to accurately count, compensate, and support this critical segment of the public health workforce.

Patients often push their doctors to prescribe antibiotics unnecessarily, increasing bacterial resistance. More trust in patients could help here. This is the surprising outcome of a study supported by the SNSF.

An AI tool could help cardiologists identify and target cells that trigger arrhythmia in patients with ventricular tachycardia, a serious heart condition.

A new HIV antiretroviral shows promise as a long-acting, oral prophylactic agent, according to a new study by Izzat Raheem, Tracy Diamond and colleagues from Merck & Co., Inc., Rahway, NJ, U.S., published in the open-access journal PLOS Biology.

Cloves have long been a staple in kitchens and traditional medicine cabinets. Known for their warm, spicy flavor, they're typically found whole or ground, and as clove oil or extract. But beyond their culinary charm, cloves are gaining scientific attention from researchers and clinicians for their potent analgesic (painkiller) properties. But could this humble spice rival ibuprofen or other commonly used painkillers?

Only 16% of all counties in the U.S. offered pregnant people the opportunity to attempt labor after a previous cesarean section between 2016 and 2021, according to University of Massachusetts Amherst research that provides the most recent national look at this trend.

Messenger RNA, or mRNA, vaccines entered the public consciousness when they were introduced during the COVID-19 pandemic, and both Pfizer-BioNTech and Moderna used the technology in developing their highly effective vaccines to fight the virus.

One of the great challenges faced by families coping with Alzheimer's disease and other forms of dementia is learning how to communicate effectively with the person impacted by the disease while also upholding their personhood, or sense of personal value.

Concordia researchers have developed a new method of monitoring and tracking how disease-causing particles, or pathogens, spread from one place to another. The tool could help contain future outbreaks of diseases like COVID-19.

For some people, sleep brings a peculiar kind of wakefulness. Not a dream, but a quiet awareness with no content. This lesser-known state of consciousness may hold clues to one of science's biggest mysteries: what it means to be conscious.

A recent systematic review and meta-analysis conducted by researchers from the Research Institute of the McGill University Health Center (The Institute) and published in eClinicalMedicine reveals that children of mothers with gestational diabetes or fathers with type 2 diabetes have higher chances of developing type 1 diabetes than kids whose parents do not have any type of diabetes. The study provides insights that could help doctors identify at-risk children earlier.

Younger adults who experience frailty face a higher risk of death and emergency hospital admission, according to new University of Dundee research published in The Lancet Healthy Longevity. The study, led by Dr. Daniel Morales from the University's School of Medicine, explored whether the electronic frailty index (eFI), which is already used for older adults, could also identify vulnerable younger people who might benefit from early support.
