A Dutch designer wants to take the elements that make jellyfish glow and apply them to trees. Daan Roosegaarde envisions trees serving as streetlights one day. With the help of the Dutch government, he's developing his research here in the States, where genetic modification isn't as strictly regulated.
Ellis Hamburger for The Verge has the interview:
As my eyes adjust, it gets brighter. Roosegaarde’s specimen was created by genetically modifying its molecular structure to include luciferin, a chemical that gives jellyfish their radiant glow. "I’m completely obsessed with jellyfish," Roosegaarde says. "They create their own light without a battery or solar panel." Roosegaarde’s plant is nowhere near as vibrant as a jellyfish or a fern from Avatar — it’s in fact still quite dim — but serves as a proof of concept for his technology, which he hopes to employ on a much larger scale.
He asks me to imagine trees filled with glowing leaves lining highways to light the way for drivers, or a street lined with energy-neutral trees instead of electric street lamps. Roosegaarde says, "In a time where governments are shutting down street lights to save money, can we not make it more natural?" The plants were engineered in collaboration with BioGlow founder Dr. Alexander Krichevsky, who first revealed his technology back in January. The idea for glowing plants has been around for at least a few years, but Krichevsky claims that his are the first real prototypes.

It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
It's not just a case of "what doesn't kill you makes you stronger."
- A new study suggests children who endure trauma grow up to be adults with more empathy than others.
- The effect is not universal, however. Only one kind of empathy was greatly effected.
- The study may lead to further investigations into how people cope with trauma and lead to new ways to help victims bounce back.
