Happy gut bacteria are the best bacteria.

A minority of women go through extreme PMS – and now we know why

Researchers have discovered that a minority of women go through severe premenstrual syndrome (PMS) symptoms due to a hormonal abnormality.

Why do men even have nipples?

If you feel silly for wondering why men have nipples you can feel a bit better knowing that Darwin had the same question.

Ancient fish solves one of your childhood mysteries about teeth

A tale of milk teeth and ancient fish.

What causes running pain and why it’s a sign ‘you’re doing it right’

There’s a common misconception that some people just aren’t made to run. Here’s what science says, instead.

Browse the brain one cell at a time in the most detailed atlas ever made

And the Allen Brain Atlas is free to use. Hurray!

This 3D printing of a female clitoris shows how much you don’t know about female genitalia

Take a look at this image. What do you think it is?

Synthetic heart tissue bypasses the use of animal-sourced valves, arteries and veins

The synthetic tissue is safer and more reliable than that sourced from dead pigs or human cadavers.

A smart brain is not only big, but blood thirsty too

The brain needs a lot of blood to be smart.

Detailed new map of human brain reveals almost 100 new regions

Just like space, the human brain has plenty of uncharted territory.

Research suggests turtle shells evolved for digging, not protection

The discovery highlights how trait functions can change with evolution.

Researchers find what’s giving you dandruff – and it’s probably not what you think

Dandruff is the most common scalp condition, yet we know surprisingly little about it.

Why we get goosebumps

Goosebumps are strange. We get goosebumps when we’re cold, when we’re afraid, and sometimes when we’re really excited – three very differen

Scientists create artificial skin that sprouts new hairs and sweats

Creating artificial skin may sound weird, but it can be extremely useful (or even life saving) for people who suffered from burns or any type of similar accident; it is also useful for testing drugs or cosmetic products. Skin transplants are a growing need, and many teams from across the world hope to one day be able to create artificial

Scientists find genes that influence hair color and shape

A new study has mapped the genetic variations responsible for differences in the distribution, shape and colour of facial and scalp hair.

How do we hear and other eary functions

I like my ears. I’ve been told they go well with my face and they’re really efficient at holding my hair out of my eyes, like ad hoc hair band. And I get two of them! Yay for ears!
But (spoiler alert) these are not our ears’ primary functions. The workings of our ears’ internal mechanisms underpin two of our senses — hearing and balance (called equilibrioception).

How the eye works: what you can’t see

How eyesight works and other functions.

Depression in children changes the brain for life

Researchers at the Washington University School of Medicine in St. Louis, looking into the effects depression has on the brain have found proof linking the disorder with abnormal brain development in preschoolers. Their study, published in the journal JAMA Psychiatry, shows how gray matter is thinner and lower in volume in the cortex, an area of the brain that plays a key role in processing emotions.

Popeye gene mutations linked to heart and muscle conditions

Scientists from the University of Ferrara, Italy collaborating with the Beijing Genomics Institute have isolated a gene that, when mutated, causes muscle tissue to become significantly weakened and damaged. Their findings, published in The Journal of Clinical Investigation, show how the gene, dubbed Popeye domain containing-1, has a role in ‘gluing’ muscles cells together.

Scientists image organs at microscopic scales

In a new study published in Nature, researchers have demonstrated a technique that allows the mapping of organs at microscopic scales.
