Vocal learning in birds is a lot like how people learn language.
Could mating preferences, like females preferring males who sing complex songs, affect the evolution of learning? Insights from birds could have clues for how people learn throughout their lives.
Biological factors shape sexual preference.
A new study of nearly 500,000 individuals finds that many genes affect same-sex behavior, including newly identified candidates that may regulate smell and sex hormones.
Evolution has no final endpoint in mind.
If you go by editorial cartoons and T-shirts, you might have the impression that evolution proceeds as an orderly march toward a preordained finish line. But that's not right at all.

Is privacy what you can’t see, or where you don’t look?
Privacy starts with the body and extends to digital data. There are few rules governing what companies can do – yet people can't effectively protect their own privacy.
Big changes from one frame to the next can signal trouble.
A new technique for detecting deepfakes conceives of videos as flip-books and looks for changes in successive frames of a sequence.
On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun.
This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
What does a future full of AVs mean for all the spaces reserved for downtown parking?

It’s a mess, but is it all bad?
New technologies and services aren't creating irreversible damage, even though they do generate some harms. Preemptive bans would stifle innovation and block potential solutions to real problems.
Lab-grown organs may not be so easy to transplant into a patient.
The idea behind regenerative medicine is that the patient is both the donor and recipient of healthy tissue grown from stem cells. But sometimes the transplanted cells are rejected. Now we know why.
Is there still time to reach the ‘off’ button?
Legal bans and moratoriums on other emerging technologies need not be permanent or absolute, but the more powerful a technology is, the more care it requires to operate safely.
