Oldest Proteins Ever Recovered Found In 3.8 Million-Year-Old Eggshell

Researchers working in Africa have uncovered 3.8 million-year-old protein fragments encased in an ostrich eggshell. These biological building blocks are millions of years older than the oldest DNA ever found, highlighting the possibility of recovering ancient proteins from extinct animals — and even the remains of early humans.

These Are The First Ever Images Of A Single Folded Protein

Forgive this picture for being a little blurry, because you’re actually looking at the first ever image of a single folded protein.

The Phoenix Effect Lets You Unboil An Egg

Researchers at Itmo University in Russia have found a way to fold mutilated proteins back into the right shape. Afterwards, the proteins work better than they did before. They call it the “Phoenix Effect”: an exhausted protein is ripped apart by heat, only to rise again better than before.

Meet The Protein That Plugs A Sperm Into An Egg During Fertilisation

The successful union of egg and sperm in fertilisation depends on a sperm cell’s ability to get through an egg’s thick protective coating and latch itself to its membrane. A study published in the journal Andrology yesterday gives us our first look at the protein responsible for the tie-down.

We're Another Step Closer To Impotence Drugs From Spider Venom

The bite of a Brazilian wandering spider might not kill you, but it can make you wish you were dead. The cocktail of toxins in its venom produces a suite of not-so-delightful effects like swelling, intense pain and paralysis. If you’re male, you also get a painful erection that lasts for hours.

Your Brain's Sex System Needs This Protein To Survive

Sometimes, bad luck leads to insights. A study published today in the Journal of Clinical Investigation has added a new twist to the way the system that controls puberty in mammals develops inside the brain, thanks to two brothers who both inherited a combination of genes for Kallmann syndrome.
