Mars Diffracts! X-ray Crystallography and Space Exploration…

Astrobiologist and intrepid science communicator Lewis Dartnell reveals the crucial role that x-ray crystallography is playing in understanding the formation and history of our planetary neighbour, Mars.

Scientists can now grow real vaginas in the lab. Vaginas. Sex toys will never be the same.

For women and girls born without vaginas or ones that are partial or deformed, the good news is that scientists can now grow you a brand new real live vagina from your own cells. For everyone else, the good news is that scientists can now grow perfect vaginal replicas of other people’s vaginas, for… reasons. Where do I pre-order?

Scientists invent an injectable oxygen particle to let you breathe without breathing

Just trying to inject raw oxygen or atmospheric air into your bloodstream would be really bad— I wouldn’t recommend it. But when airways are obstructed, every second counts as the oxygen level in your body drops. Now, science has created the perfectly sized injectable oxygen particle by gently wrapping a handful of oxygen molecules in lipids, creating microscopic gel-caps of oxygen that are the bite size for your red blood cells, providing emergency oxygen for when breathing normally isn’t an option.

Earth’s upper atmosphere—below freezing, nearly without oxygen, flooded by UV radiation—is no place to live. But last winter, scientists from the Georgia Institute of Technology discovered that billions of bacteria actually thrive up there.
Expecting only a smattering of microorganisms, the researchers flew six miles above Earth’s surface in a NASA jet plane. There, they pumped outside air through a filter to collect particles.
Back on the ground, they tallied the organisms, and the count was staggering: 20 percent of what they had assumed to be just dust or other particles was alive. Earth, it seems, is surrounded by a bubble of bacteria.

And now, here’s a video of two tortoises having sex

Gotta watch it with sound on, all the way to the glorious conclusion.

Eye of the Tiger…err, chicken: New state of matter found in chicken eyes
From the article:
"Along with eggs, soup and rubber toys, the list of the chicken’s most lasting legacies may eventually include advanced materials, according to scientists. The researchers report that the unusual arrangement of cells in a chicken’s eye constitutes the first known biological occurrence of a potentially new state of matter known as ‘disordered hyperuniformity,’ which has been shown to have unique physical properties."
My first question is, can this new state of matter be breaded and deep-fried?

How Olympians have changed since 1924

Today’s athletes are bigger, stronger and faster by a long shot than they were 90 years ago. Better diet, training and a little bit of shhh hush hush have made it possible, but how much have things changed?
