Casu marzu is a traditional Sardinian sheep milk cheese, notable for containing live insect larvae. It is found almost exclusively in Sardinia, Italy.

Casu marzu is created by leaving whole Pecorino cheeses outside with part of the rind removed to allow the eggs of the cheese fly Piophila casei to be laid in the cheese. A female P. casei can lay more than five hundred eggs at one time. The eggs hatch and the larvae begin to eat through the cheese. The acid from the maggots' digestive system breaks down the cheese's fats, making the texture of the cheese very soft; by the time it is ready for consumption, a typical casu marzu will contain thousands of these maggots.

Hemocyanins are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O2). They are second only to hemoglobin in frequency of use as an oxygen transport molecule. Unlike the hemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph. Oxygenation causes a color change between the colorless Cu(I) deoxygenated form and the blue Cu(II) oxygenated form. ...

Did you know one quart of horseshoe crab blood costs $15,000 dollars?

The critter's blue blood is a sort of bacteria killing machine that clots around ‘invaders’, eliminating them and protecting horseshoe crabs from lethal infections. Researchers have been harnessing the power of this blue blood to test medical supplies for contamination.

During this experiment, spiders were exposed to a variety of drugs to help determine their effect on the brain.

Spiders who had been given marijuana started out well enough, but were unable to maintain focus.

Benzedrine (speed) produced spiders who spun enthusiastically, though no great thought or care was put into the web design.

Caffeine, one of the most common stimulants taken by humans, produced an erratic web.

Chloral hydrate, an ingredient in sleeping pills, made the spiders doze off after barely getting started on the web.

Though this 1995 experiment sought to determine toxicity of drugs, it was a continuation of experimentation of spiders on drugs that had started in 1948 by P. N. Witt. ...

Scientists in Japan have built a levitating train that in recent trials hit speeds of almost 500 km/h. It's hoped that by 2027, this floating 'maglev' train will cut 55 minutes off the current travel time between Nagoya and Tokyo on today's high-speed trains.

This sculpture is constructed by quickly rotating a rope stretched from ceiling to floor through white light. The vibrating string becomes invisible, but the white light that’s being reflected off the rope becomes visible in an exchange that let’s our eyes see magic, as real as science can make it.

The colors change and twist, forming double-helixes that stem from the shape of the swinging rope. Some of these light sculptures are small and handheld, but many of the larger ones include touch screens that allow viewers to adjust the beams. All of them are spinning at very high speeds that result in a constantly moving body of light. ...
