It’s been five years since COVID was declared a global pandemic. Local, national and global public health agencies mobilized to contain the spread of COVID, but experts worry that backlash against measures like lockdowns have made today’s systems less capable of handling a disease of similar scale. Now the U.S. faces a tuberculosis outbreak in Kansas that underscores the importance of public health infrastructure.

Not much passes into our brain from the rest of our body, to the chagrin of drug makers everywhere. So it should be cause for concern when a study found that microplastics were somehow ending up in our brain, says chief opinion editor Megha Satyanarayana. She takes a step back and brings us into the wider world of plastics and the way petroleum chemicals can become pollutants far beyond the factories where they are made. Plus, Satyanarayana discusses the Scientific American opinion section and her column Cross Currents, which aims to decode the science from the headlines.

It’s fairly strange that humans, unlike many other mammals, don’t have hair all over. Our lack of body hair and wide geographic distribution led to the variation of sun-protective melanin in our skin. For the hair that remains, why did some groups develop curls while others did not? Biological anthropologist Tina Lasisi takes host Rachel Feltman through her work on understanding the roots of hair types. Plus, they discuss what we might learn from “chemo curls” and how developmental shifts change the extent and texture of hair during puberty.

Scientists now agree that COVID spreads via airborne transmission. But during the early days of the disease, public health officials suggested that it mainly did so via close contact. The subsequent back-and-forth over how COVID spread brought science journalist Carl Zimmer into the world of aerobiology. In his new book Air-Borne: The Hidden History of the Life We Breathe, Zimmer examines the unseen life in the air around us.

A subtype of H5N1 bird flu that has been found in cattle for the first time suggests that the virus jumped from birds to the animals twice. A headline-making study estimates that we have a spoon’s worth of microplastics in our brain. Streams of rock from a cosmic impact created the moon’s two deep canyons, Vallis Schrödinger and Vallis Planck. A large study shows that people feel their best in the morning and their worst at midnight. Bonobos can tell when humans don’t know something—and try to help us.

The first few weeks of the Trump administration have been marked by chaos and confusion for the nation’s health and science agencies. A funding freeze broadly targeting language around diversity, equity and inclusion has agencies evaluating research and initiatives. A hold on public communications from health agencies is affecting public health reporting to people in the U.S.—and to the World Health Organization. Entire websites have gone dark as agencies have tried to comply, though archivists are preventing critical datasets from disappearing. Max Kozlov, a Nature reporter who covers biomedical science, joins host Rachel Feltman to walk through what the next four years might hold for research and researchers in the U.S. Overall, the orders have caused uncertainty for scientists in the nation, and associate health editor Lauren Young discusses the frustration and fear she’s hearing from them.
