Tyler Nelson, a postdoctoral researcher at the University of Florida, studies the neurobiology of pain, a choice partly motivated by his own frustrations with a neuromuscular disability. Last October, he applied for a grant at the National Institutes of Health that, if awarded, would support his dream of someday running his own lab. But, earlier in February, he learned that …

Two dairy workers in Michigan may have transmitted bird flu to their pet cats last May, suggests a new study published on Thursday by the Centers for Disease Control and Prevention. In one household, infected cats may also have passed the virus to other people in the home, but limited evidence makes it difficult to ascertain the possibility. The results …

At the nation’s borders, federal workers keep the country safe in many ways: Some investigate sick passengers. Some examine animals for dangerous pathogens. And some inspect plants for infestations that could spread in this country. Late last week, the Trump administration dispatched hundreds of those federal employees with the same message that colleagues at other agencies received: Their services were …

The Covid-19 vaccines were powerfully protective, preventing millions of deaths. But in a small number of people, the shots may have led to a constellation of side effects that includes fatigue, exercise intolerance, brain fog, tinnitus and dizziness, together referred to as “post-vaccination syndrome,” according to a small new study. Some people with this syndrome appear to show distinct biological …

The viruses we know best are the ones that make us sick — the influenza viruses that send us to bed and the smallpox viruses that may send us to the grave. But healthy people are rife with viruses that don’t make us ill. Scientists estimate that tens of trillions of viruses live inside of us, though they’ve identified just …

Pope Francis, who remains hospitalized, has bilateral pneumonia, the Vatican said on Tuesday. The term simply means pneumonia in both lungs, said Dr. James Musser, director of the center for infectious diseases at the Houston Methodist Research Institute. He added that, without examining a patient, he could not say anything specific about his condition. In general, pneumonia is an infection …

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 Dec. 22 of that year …

Scientists have long struggled to understand how human language evolved. Words and sentences don’t leave fossils behind for paleontologists to dig up. A genetic study published on Tuesday offers an important new clue. Researchers found that, between 250,000 and 500,000 years ago, a gene known as NOVA1 underwent a profound evolutionary change in our ancestors. When the scientists put the …

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, more than 370 million people …

Louis Pasteur was at his most comfortable when working in his Paris laboratory. It was there that he had some of his greatest scientific triumphs, including experiments that helped confirm germs can cause disease. “Everything gets complicated away from the laboratory,” he once complained to a friend. But in 1860, years before he became famous for developing vaccines and heating …
