Why scientists just mapped every synapse in a fly brain

To really understand the human brain, scientists say you'd have to map its wiring. The only problem: there are more than 100 trillion different connections to find, trace and characterize. But a team of scientists has made a big stride toward this goal, a complete wiring diagram of a teeny, tiny brain: the fruit fly larva.

Venus and Earth: A tale of two 'twins'

Planetary scientists announced some big news this week about our next-door neighbor, Venus. For the first time, they had found direct evidence that Venus has active, ongoing volcanic activity.

Could de-extincting the dodo help struggling species?

As a leading expert on paleogenomics, Beth Shapiro has been hearing the same question ever since she started working on ancient DNA: "The only question that we consistently were asked was, how close are we to bringing a mammoth back to life?"

How well does a new Alzheimer's drug work for those most at risk?

A new drug for Alzheimer's disease, called lecanemab, got a lot of attention earlier this year for getting fast-tracked approval based on a clinical trial that included nearly 1,800 people. It was the most diverse trial for an Alzheimer's treatment to date, but still not enough to definitively say if the drug is effective for Black people. "[In] the world's most diverse Alzheimer's trial, a giant trial of 1,800 people that lasted for a much longer time than most trials did, we're still not sure that all of the groups that are at highest risk of Alzheimer's disease actually see any kind of benefit," says Dr. Jonathan Jackson, Assistant Professor of Neurology at Harvard Medical School.
