The results are intriguing, but analysing the atmospheres of exoplanets is no easy task.
The Cambrian explosion, about 530 million years ago, was when most of the major groups of animals first appear in the fossil record.

Flies often beat out competitors for food because of their specialized sensing organs called antennae.
Teaching sex and gender more accurately can counter gender stereotypes and encourage all students to study STEM.

‘Don’t Say Gay’ bills claim to use science to justify a binary definition of sex based on certain traits. But the biology of sex and gender is not so simple.
Humans have been making symbols for numbers for thousands of years. Different cultures developed their own symbols, but all use addition and multiplication, suggesting arithmetic is a universal truth.
Summer humidity can change the way your hair is behaving – but what’s the science behind that?

Studying a guillemot colony for 50 years has provided unique insights into how climate change and oil spills affect seabird populations.
The same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code.

Many of the amino acids that make up proteins are encoded by genetic material in more than one way. An information theorist explains how principles of nature may account for this variance.
For many people, trying to lose excess fat is very difficult without help. Effective treatment is available when obesity affects health.

There’s no single reason many Asian animals spread to Australia but few went the other way – but climate, geography and the slow drift of tectonic plates all played a role.
While some people may be older in chronological age, their biological age might be much younger.

Aging is a culmination of factors spanning from your cells to your environment. A number of interconnected processes determine how quickly your body is able to repair and recover from damage.
E. coli as a model organism helped researchers better understand how DNA works.
