The common thread in severe COVID-19 
New studies point to a single molecular explanation for 20 percent of critical COVID-19 cases: insufficient or defective type I interferons.
Lonely flies, like many humans, eat more and sleep less
If COVID-19 lockdowns scrambled your sleep schedule and stretched your waistline, you're not alone. Fruit flies quarantined in test tubes sleep too little and eat too much after only one week of social isolation.
Study reveals how smell receptors work
The first-ever molecular images of an olfactory receptor at work answer decades-old questions about odor recognition.
When ant colonies get bigger, new foraging behavior emerges
By increasing the size of ant colonies bit by bit, scientists identified the mechanism responsible for the evolution of mass raiding behavior.
How cells draw on memories of past inflammation to respond to new threats
A new study uncovers a near-universal mechanism behind this phenomenon, known as inflammatory memory.
Hunting for TB's most vulnerable genes
Not every gene that's essential in tuberculosis is also vulnerable to attack. A new study ranks essential genes by vulnerability, allowing researchers to better prioritize future drug targets.
Putting the brakes on immune reactions
Helper T cells may play a dual role in the immune system, both encouraging and suppressing the process by which B cells mature.
Identifying the spark of desire in fruit flies
In Drosophila’s neural circuitry for courtship, researchers discover a configuration that enables a male fruit fly to be persistent, yet flexible in his pursuit of a female.
Scientists discover a new class of neurons for remembering faces
Our brains have sensory cells, which process the faces that we see, and memory cells dedicated to storing data from person encounters. But until now, a hybrid neuron capable of linking vision to memory—and explaining how we recall familiar faces—remained elusive.
Toward the first drug to treat a rare, lethal liver cancer
After scouring more than 5,000 compounds, scientists have identified several new classes of therapeutics that may help treat fibrolamellar carcinoma.
