Test-Tube Burger

Now that the first test-tube burger has been introduced in London, experts are split on whether this is a fortuitous scientific breakthrough or a culinary abomination. Debating the subject for Great Britain’s Channel 4 are chef Yotam Ottolenghi and Joanna Blythman, author of several food books, including WHAT TO EAT.

World’s First Nuclear Reactor

Today on SciShow, Hank Green brings us a little science history, telling us the tale of the world’s first nuclear reactor, which was built a team of scientists and students led by Enrico Fermi in a converted squash court under a football field in Chicago. Yes, that Chicago.

Science Fiction Becomes Fact

Where science fiction becomes science fact – that is the place Hank Green is exploring in today’s episode of SciShow. Many inventions we use today were first imagined in stories that described fantastical futures. Hank talks about the origins of four of these: the cell phone, the submarine, the telemanipulator (or robot arm), and the taser. Blast off for knowledge!

Iridium

The dense metal with a high melting point is quite useful as a material for manufacturing crucibles or the tips of spark plugs. But what about vodka glasses?

Vanishing Honey Bees

You’ve probably heard about the sudden and mysterious drop in honey bee populations throughout the U.S.A. and Europe. Beekeepers used to report average losses in their worker bees of about 5-10% a year, but starting around 2006, that rate jumped to about 30%. Today, many large beekeeping operations are reporting that up to 40 or 50 percent of their swarms have mysteriously disappeared. This massive die-off of honey bee populations has been dubbed colony collapse disorder, and it is a big, big deal. Find out more in today’s episode of SciShow with Hank Green.

Through the aid of slow-mo, Eepybird shows us their homemade bottle rockets and the science behind their viral chemical reactions involving Mentos and Diet Coke.

Length of Time Redefined

The optical lattice clock, which uses a laser to measure vibrating atoms, could offer a more accurate definition of the second.

Inventor Whisked Off to Jail

 

Krister Evertson, a scientist who researched alternative fuels, was driving near his mother’s home when his car was run off the road by a SWAT team with automatic weapons. They arrested him because, in a transaction related to his alternative fuel cell experiments, he forgot to place a federally mandated safety sticker on the box when it was shipped. Although the sodium was properly secured, Evertson spent two years in prison — a shocking miscarriage of justice. H/T Heritage Foundation
