What comes after Omicron? New variants are emerging.

At least 300 Americans have died from COVID-19 every day for the past three months, and roughly 50,000 new COVID-19 infections were reported in the U.S. every day in September—all caused by new sublineages of Omicron: BA.2, BA.2.12.1, BA.4., and BA.5. To date there have been more than 200 newer Omicron sublineages and their derivatives. What does mean for the new boosters and treatments?

Why is this old military bunker filled with human blood and urine?

Some 400,000 specimens from German citizens, collected over four decades and stored in an old military bunker, trace the rise—and sometimes the fall—of chemical pollutants in an industrial country. It's the best record we have of how chemicals contaminate our bodies.

How will we know when the pandemic is over?

A pandemic is a disease outbreak spanning several countries that affects many people. The WHO is responsible for declaring when an outbreak has grown into a pandemic and deciding when it stops being a public health emergency of international concern.

The microbe behind the baby formula recall could pose a threat to our food safety

Cronobacter sakazakii is less well-known than other food-borne pathogens like E. coli or Salmonella, but it can wreak havoc in vulnerable populations like newborns or people with compromised immune systems—and it has evolved traits that make it difficult to destroy.
