Dangerous pathogens left unsecured at labs across Africa. Halted inspections for mpox, Ebola and other infections at airports and other checkpoints. Millions of unscreened animals shipped across borders. The Trump administration’s pause on foreign aid has hobbled programs that prevent and snuff out outbreaks around the world, scientists say, leaving people everywhere more vulnerable to…
The Trump administration’s decision to withdraw foreign aid and dismantle the U.S. Agency for International Development is likely to cause enormous human suffering, according to estimates by the agency itself. Among them: up to 18 million additional cases of malaria per year, and as many as 166,000 additional deaths; 200,000 children paralyzed with polio annually,…
An obscure but influential program that gave detailed public health information to about half of the world’s nations will fold as a result of the Trump administration’s freeze on foreign aid.

Now every other world in our solar system will be visible among the stars at the same time — if you know where to look. According to Gerard van Belle, director of…
At the nation’s borders, federal workers keep the country safe in many ways: Some investigate sick passengers. Some examine animals for dangerous pathogens.

Astronomers on Tuesday said that the asteroid designated 2024 YR4 had become the most likely sizable space rock ever forecast to impact planet Earth. The object, first detected in December, is 130 to 300 feet long and expected to make a very close pass of the planet in 2032. Its odds of impacting Earth on…
At the height of the Covid-19 pandemic, millions of people in poor nations died literally gasping for breath, even in hospitals. What they lacked was medical oxygen, which is in short supply in much of the world. On Monday, a panel of experts published a comprehensive report on the shortage. Each year, the report noted,…
The words “optimal” and “optimize” derive from the Latin “optimus,” or “best,” as in “make the best of things.” Alessio Figalli, a mathematician at the university ETH Zurich, studies optimal transport: the most efficient allocation of starting points to end points. The scope of investigation is wide, including clouds, crystals, bubbles and chatbots. Dr. Figalli,…
President Trump’s order that the United States exit the World Health Organization could undo programs meant to ensure the safety, security and study of a deadly virus that once took half a billion lives, experts warn. His retreat, they add, could end decades in which the agency directed the management of smallpox virus remnants in…
