Alerts issued as smoke from Canadian wildfires makes for unhealthy air in northern Minnesota

It may start with forgetfulness, lapses in memory and confusion.

A new study to be presented at the SLEEP 2025 annual meeting found that adolescents who prefer to sleep and wake up later ("night owls") reported greater impulsivity than those who prefer to sleep and wake up earlier ("morning larks").

A trial of an interactive game that trains people to alter their brain waves has shown promise as a treatment for nerve pain—offering hope for a new generation of drug-free treatments.

Moderna Inc. gained U.S. approval for a new COVID vaccine for a narrower group of people, in the latest sign that regulators are restricting access to immunizations under the leadership of Health and Human Services Secretary Robert F. Kennedy Jr.

Older adults are quite aware of their financial abilities—and these abilities actually improve with age—that is, until dementia sets in, according to new research from Binghamton University, State University of New York.

As the global population ages, the risk of developing neurodegenerative diseases such as dementia, Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS) continues to rise. But the molecular mechanisms behind the deterioration of brain cells have remained elusive.

A new, highly transmissible COVID subvariant has been detected in California—heightening the risk of a potential summer wave as recent moves by the Trump administration threaten to make vaccines harder to get, and more expensive, for many Americans, some health experts warn.

As the U.S. population ages and dementia cases rise, many people are asking whether it is possible to prevent this devastating disease. According to a new study, the answer may be on your plate: People who followed a dietary pattern known as the MIND diet were significantly less likely to develop Alzheimer's disease or related forms of dementia.

In early April, President Donald Trump gathered dozens of hard-hat-clad coal miners around him in the White House East Room. He joked about arm-wrestling them and announced he was signing executive orders to boost coal production, "bringing back an industry that was abandoned," and to "put the miners back to work."

2 June 2025 Fellow Regional Directors, Distinguished Colleagues, Partners, It is my great honour to join you today for the signing of the Regional QPT Joint Statement. The establishment of a Regional Quadripartite One Health Coordination Mechanism is a major step forward for the health and resilience of our Region. The health of people, animals, and ecosystems is deeply interconnected. In the Eastern Mediterranean Region, we have seen firsthand the devastating consequences of zoonotic outbreaks, antimicrobial resistance, and foodborne diseases—challenges that demand a unified, multisectoral response. With 18 of 22 countries in the Region having reported emerging zoonotic diseases in recent years, and with millions affected annually by foodborne illness and AMR, the urgency of One Health implementation could not be clearer. This joint mechanism strengthens our collective ability to prevent, detect and respond to these threats—ensuring coherence, avoiding duplication, and making the best use of resources. It reflects our shared commitment to advancing health security and sustainable development. WHO is proud to stand alongside FAO, UNEP, and WOAH as part of this effort. Together, through our new Regional One Health Action Plan, we will support countries with the tools, coordination, and political commitment needed to turn vision into action. The implementation of the One Health approach is not optional but essential. Let us seize this opportunity to build a healthier and safer world for present and future generations— One Region, One World, One Health, and One Commitment. Read more...

Results from a new animal study suggest that microscopic plastic particles found in food and beverages may affect glucose metabolism and harm organs such as the liver. The findings raise concerns about potential health risks in people and point to the need for more research.

A three-year exercise program improved survival in colon cancer patients and kept disease at bay, a first-of-its-kind international experiment showed.

Colon cancer is the third most prevalent form of cancer in the U.S., and while screening has helped detect and prevent colon cancer from spreading, major advancements in treating colon cancer have lagged.

A new study that followed almost 200,000 people for several decades has found that when it comes to heart health, the quality of food consumed matters as much as following a low-carbohydrate or low-fat diet. The results suggest that choosing healthy, high-quality foods is key to protecting the heart.

With rates of obesity and anxiety both on the rise—especially among younger Americans—new research suggests that the two conditions may be connected through interactions between the gut and the brain. The study, conducted in mice, links diet-induced obesity with anxiety-like symptoms, alterations in brain signaling and differences in gut microbes that may contribute to impaired brain functioning.

New research that used blood markers to measure linoleic acid levels and their relation to cardiometabolic risk adds evidence that this omega-6 fatty acid may help to lower risks of heart disease and type 2 diabetes. The findings challenge claims that seed oils are harmful to cardiometabolic health.

A dual-target CAR T cell therapy approach shows promise for slowing tumor growth in a notoriously aggressive and fast-growing brain cancer. Tumors became smaller after the experimental CAR T cell therapy in nearly two-thirds of patients.

Many men with aggressive prostate cancer can experience a high rate of recurrence despite treatment.
