Scientists Say: Wavelength
When something travels as a wave — such as light — scientists can measure it by its wavelength, the distances between the peaks.

How to tell if a T. rex is expecting
A chemical test of tyrannosaur bone can determine whether the dino was pregnant — and therefore a female.

Pacific islanders got a double dose of Stone Age DNA
Unlike other people, certain Pacific Islanders inherited DNA from two ancient human ‘cousins.’

Smash hit: Making ‘diamond’ that’s harder than diamonds
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.

Black hole smashup sent out ‘yottawatts’ of power
When two black holes collided, they released a lot of energy in gravity waves. How much? How about 36 septillion yottawatts of power!

Genes: How few needed for life?
Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.

Breathing very dirty air may boost obesity risk
Breathing dirty Beijing air made rats heavier and less healthy than rats breathing clean air. Scientists now worry such polluted air may do the same thing to people.
