The aye-aye lives in the forests of Madagascar. Despite looking like a very scared rodent, the aye-aye is a kind of lemur with a bushy tail and super-thin, elongated middle fingers that they use to dig grubs out of hollow branches. Aye-ayes also have huge lower incisors to chew through wood and bamboo—and in captivity they’ve been known to chew through concrete cinder blocks ...

Demodex folliculorum and Demodex brevisare are parasitic mites that particularly favour the hair follicles of eyebrows and eyelashes and measure a mere fraction of a millimeter long. They crawl about your face in the dark to mate and then crawl into the pores to lay their eggs and die. Healthy adults have around one or two mites per square centimetre of facial skin, though people with the condition rosacea can have 10 times more. Demodex does not have an anus and therefore cannot get rid of its faeces. Instead, their abdomen gets bigger and bigger, and when the mite dies it decomposes and releases its faeces all at once into the pore. ...

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. ...

This 22-year-old man had a car accident last year and as a result his nose became infected and deformed. Doctors weren’t able to repair it, but decided to take cartilage from one of the young man’s ribs to grown a new nose. The nose, which is temporarily attached to his forehead, has been developing for 9 months and is ready to be transplanted.

You'll need to watch the whole thing, don't skip anywhere.

Using high-resolution atomic force microscopy, a hydrogen bond has been imaged for the first time. This technique is quite similar to the one used to photograph bonds breaking and reforming that was announced earlier this year.

Varieties of the inky cap mushroom can be around the world. While they are edible, ingesting alcohol while eating the mushrooms increases symptoms of nausea and vomiting, and can even cause a heart attack.

After the mushroom has released its spores, the cap begins to liquefy. The thick black liquid that is seen dripping from the edges is how the inky cap got its name.
