Wildfire smoke is obvious, but its long-term health impacts are not

The brain controls the release of glucose in a wide range of stressful circumstances, including fasting and low blood sugar levels. However, less attention has been paid to its role in day-to-day situations.

A topical fluorescent molecular contrast agent, PARPi-FL, can detect basal cell carcinoma through intact skin in as little as five minutes in ex vivo human tissues, according to new preclinical research published in The Journal of Nuclear Medicine. Data confirmed that PARPi-FL is non-toxic to the skin and does not cause systemic side effects, making it a potential one-stop-shop for diagnosis and management of basal cell carcinoma.

People recovering from heart failure should consider improving the regularity of their sleep, a study led by Oregon Health & Science University suggests.

Researchers at the Complexity Science Hub (CSH) analyzed 13 million inpatient hospital stays involving around 4 million individuals in Austria: Although about 20% of the population in Austria does not hold Austrian citizenship, this group accounts for only 9.4% of hospital patients and 9.8% of total hospital nights.

In modern medicine, few diseases are as steeped in emotive and metaphorical language as cancer. It's often spoken about as a battle pitched against a cunning enemy. A foe to be beaten. These phrases are so common that we don't think twice about them, but they deeply affect how we understand cancer, how people experience it and how we care for the people who live with it.

Daily sleep and activity are fundamental to both physical and mental health. Although previous studies have largely emphasized quantitative aspects such as sleep duration and physical activity time, there is increasing focus on how daily sleep varies among days.

Cardiovascular researchers at UC Davis Health have developed a novel technique that allows scientists to study how the brain communicates with other organs, like the heart or gut. The new method preserves the brain tissue in animal research while simultaneously collecting living (unfixed) samples from other organs.

A remotely delivered behavioral intervention can reduce variability in systolic blood pressure, expressed as the coefficient of variation (BPCoV), according to a study published online Aug. 12 in Scientific Reports.

For patients with inflammatory bowel disease and obesity, bariatric surgery is associated with improved inflammatory bowel disease-related outcomes, according to a study published online July 22 in BJS Open.

A new study by USC Leonard Davis School of Gerontology researchers shows that Americans with less education are aging faster than their peers with more schooling, and the gap has grown over the last 30 years.

Jeffrey Carson spent more than a decade persuading hospitals that fewer, resource-saving blood transfusions work just as well as more frequent transfusions for most patients. More recently, the Rutgers internist finished a massive study that indicates a major exception to the rule: anemic heart attack patients.

As we age, our cells replicate, and the DNA in these cells can acquire mistakes—or mutations—every time the sequence is copied. Most newly acquired mutations are harmless, but some can tip the balance toward cancer development later in life.

Prioritizing communications between patients and health care providers and increasing patient education about chronic obstructive pulmonary disease (COPD) could help improve patient care, according to a new study published in the July 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation.

Research out of the University of New Hampshire shows that communities that were easier for people to lace up and get out for a walk during the COVID-19 pandemic also helped lower the impact of mental health issues, like stress and anxiety.

Brucellosis is a serious and often neglected disease endemic to many low- and middle-income countries around the world. Because it shares many of the same clinical symptoms as malaria—including fever and joint pain—it can be misdiagnosed.

Scientists at St. Jude Children's Research Hospital demonstrated for the first time that the protein midkine plays a preventative role against Alzheimer's disease. Midkine is known to accumulate in Alzheimer's disease patients. Now, researchers have connected it with amyloid beta, a protein that accumulates in the brain, causing assemblies that are a hallmark of Alzheimer's.

The COVID-19 virus hijacks the machinery of testicular cells that produce the hormone testosterone in order to replicate. It also appropriates the metabolic pathways of these cells and cholesterol, a precursor of testosterone, thereby altering lipid metabolism for its formation.

More than 30 million Americans rely on implanted medical devices like prosthetic joints, pacemakers and more to improve their quality of life. But implanting any foreign object into the body also carries the risk of introducing deadly fungal infections.
