The season we’re born in can have far-reaching consequences. Now, scientists are studying the links between season of birth and brain structure in healthy adults, and think genetic factors controlling brain growth play a role in these differences.
You’re looking at a rabbit’s heart beating outside the animal that once hosted it. It’s alive, pumping blood on its own thanks to a revolutionary electronic membrane that may save your life by keeping your heart beating at a perfect rate.
This is a game changer, folks. Whereas mining stem cells has been either an ethical quandary or a months-long affair, scientist can now turn any old blood cells into stem cells in just 30 seconds by dipping them in acid.
Thanks to extraordinary demand for gadgets that make us healthier, stronger, and smarter, the technology industry is putting some serious brain power behind the next generation of wearable health devices. Over the next year, a torrent of new devices is hitting the market to provide automated elite coaching, a pocket-sized clinical lab, and your own personal assistant.
Unlike the brain and spinal cord that are housed in protective bone, peripheral nerves connect regions of the body to the central nervous system like telephone cables. Peripheral nerves relay movement information from the brain to the muscles, for example, or sensory information from the skin to the brain. Remarkably, and also different from the brain and spinal cord, peripheral nerves have a tremendous capacity to regenerate when injured. Severed peripheral nerves grow about 1 mm per day (about an inch per month) until the two severed ends reconnect and innervate a once paralyzed muscle.

From intergalactic neutrinos and invisible brains, to the creation of miniature human “organoids,” 2013 was an remarkable year for scientific discovery. Here are 17 of the biggest scientific breakthroughs, innovations and advances of 2013.
I don’t feel that I’m using technology, I don’t feel that I’m wearing technology, I feel that I am technology. I don’t perceive my antenna as a device, I perceive it as a part of my body, I perceive it as an organ.
The photographer, Paul Williams, says on his YouTube page that he was on a flight from London to New York (which swings north across the Atlantic) when he noticed the aurora out his window. He took 770 three-second exposures, for a real-time length of about 38 minutes. He balanced the camera on a backpack, aimed it out the window, and hoped for the best.
What happens when a beam of light travels through transparent textured materials? If you are Alan Jaras (or Reciprocity on Flickr), you can make it refract into a gorgeous array of colors. Bridging the gap between art and science, Jaras bends, twists and turns light…like you’ve never seen.
"For new viewers: These are light refraction patterns or ‘caustics’ formed by a light beam passing through a shaped and textured plastic form. Colour is added into the clear plastic which modifies the way the plastic hardens further enhancing the patterns.The pattern is captured directly on to 35mm film by removing the camera lens and putting the transparent object in its place. The processed film is digitally scanned for uploading. Please note these are not computer generated images but a true analogue of the way light is refracted by the objects I create."
