New laser-printed material based on the structure of bone is lighter than water, as strong as steel

I was blown away by this until I realised how heavy a bucket of water is. Lighter than a bucket of steel though, to be fair.

From reddit user tubergibbosum :

"Birds Nest Fungus

The “nests” are >1cm in diameter

The “eggs” inside are called peridioles, and are little packets of spores

The reason for the shape of a nest filled with eggs is spore dispersal; when a raindrop strikes the cup just right, the force of the impact and the shape of the cup causes the peridioles to be sent flying, thereby spreading the fungus’ spores. “

Tripod Fish (Bathypterois sp.)

Bathypterois is a genus deep sea fish known as the tripod fish. As their name suggests, the fish stands on the sea floor using three fins as support. In some species, these fins can be up to 1m long.

The fish perch on the substrate with their heads facing the current. The fins allow for their heads to be at the right level to catch drifting crustaceans and small fish.

Due to the complete darkness of the deep sea, the fish does not rely on eyesight to catch prey. Instead, it faces its pectoral fins forward and uses tactile and mechanosensory cues to identify food. Once they feel prey and realise it is edible, the fins sweep the food into the fish’s mouth.

Sperm Drinking Corydoras Catfish

Several species of Corydoras catfish are known for their unique method of mating, which involves the female drinking the male’s sperm.

When these fish reproduce, the male will present his abdomen to the female. The female will then latch her mouth onto the male’s genital opening, creating the well known ‘T-position’ many species exhibit during courtship.

The female drinks the sperm released by the male. This sperm rapidly moves through her digestive tract and exits within a couple of minutes. It is discharged simultaneously with her eggs into a pouch formed by her pelvic fins, fertilising them in the process.

During this period, the female can swim away to deposit her eggs in private. In the wild, the eggs are laid on aquatic plants whereas in the aquarium, they are often deposited on the glass.

Things I learned today: There is art on the moon.
Fallen Astronaut is the name of the small metal sculpture you see above, created by Belgian artist Paul Van Hoeydonck. It was placed on the lunar surface by Apollo 15 astronaut David Scott, along with a plaque that Scott designed, to commemorate the fallen astronauts and cosmonauts whose sacrifice helped get Scott and his fellow Apollo…-atians(?) safely to the moon and back.
Of course it wasn’t without controversy. Corey S. Powell and Laurie Gwen Shapiro have the story at Slate.

Rare Ice Disks

Although extremely rare, ice disks, also known as ice circles, do indeed appear naturally from time to time when conditions are perfect. Above are a few examples of people who have been lucky enough to stumble onto one while holding a camera.

Ice discs form on the outer bends in a river where the accelerating water creates a force called ‘rotational shear’, which breaks off a chunk of ice and twists it around. As the disc rotates, it grinds against surrounding ice — smoothing into a circle. A relatively uncommon phenomenon, one of the earliest recordings is of a slowly revolving disc was spotted on the Mianus River and reported in a 1895 edition of Scientific American.
