On his first day in office, Jan. 20, 2025, President Donald Trump began a drastic reshaping of the United States’ role in global health as part of the first 26 executive orders[1] of his new term.

He initiated the process of withdrawing the U.S. from the World Health Organization[2], which works to promote and advance global health, following through on his first attempt in 2020[3]. He also ordered staff members of the...

About 19 million children under 5 around the world suffer from severe acute malnutrition[1] every year. This life-threatening condition kills 400,000 of them[2] – that’s one child every 10 seconds.

These numbers are staggering, especially because a lifesaving treatment has existed for nearly three decades: “ready-to-use therapeutic food[3].”

Nutriset, a French company[4], was founded by Michel Lescanne[5]. He was one of two...

How does a tennis player like Carlos Alcaraz decide where to run to return Novak Djokovic's ball by just looking at the ball's initial position? These behaviours, so common in elite athletes, are difficult to explain with current computational models, which assume that the players must continuously follow the ball with their eyes. Now, researchers have developed a model that, by combining optical variables with environmental factors such as gravity, accurately predicts how a person will move to catch a moving object just from an initial glance. These results could have potential applications in fields such as robotics, sports training or even space exploration.
