Anti-aging drug rapamycin extends life as effectively as restricting calories—new research
For centuries, humans have searched for ways to extend life. Alchemists never found the philosopher's stone, but scientists have consistently shown that a longer life can be attained by eating less—at least in certain lab animals. But can we find a way to live longer while still enjoying our food?

The gut microbiome and the metabolites it produces offer promising insight into disease severity in critically ill patients. In a collaborative effort, researchers from the U.S. and the Netherlands developed the metabolic dysbiosis score (MDS), a novel biomarker index based on the levels of 13 key fecal metabolites—the chemical byproducts of digestion. The designed index can identify high-risk patients early and guide timely interventions that could save the lives of critically ill hospitalized patients.

Understanding how people visually browse their surroundings and direct their gaze in specific situations is a long-standing goal among psychology researchers. Past studies suggest that humans exhibit oculomotor biases, which are tendencies that guide the way they look at the world around them, for instance, preferentially directing their gaze around the center of what they are visually exposed to at a given time.

19 June 2025, Cairo, Egypt – Substance use across the Eastern Mediterranean Region is growing among vulnerable groups, including migrants and displaced persons. This silent crisis, taking place in the shadow of conflict, displacement, marginalization and economic hardship, is compounded by the loss of social support networks. In 2022, 6.7% of people aged between 15 and 64 in the Region had used drugs, surpassing the global average. Young men are particularly affected, with nearly 5% reporting cannabis use in the past year. The treatment gap is particularly alarming. Only 1 in 13 people with substance use disorders receive care. Substance use contributes to the spread of infectious diseases like HIV, hepatitis and tuberculosis. It takes a heavy toll on mental health, community safety and national economies. In some countries, the economic impact has reached 2% of gross domestic product. Recognizing the gravity of the situation, on 1 June 2025 the Regional Health Alliance (RHA), which brings together 18 UN agencies, led by the World Health Organization (WHO), to facilitate multilateral engagement and joint efforts to address health priorities, convened a regional technical meeting to strengthen coordination, explore joint interventions and align the response to substance use with the complex realities on the ground. Under the leadership of WHO’s Read more...
