5 animals that eat brains

Science Focus

original post »


1. Lumholtz' tree kangaroo (Dendrolagus Lumoltzi)

Adorable though they may be, these marsupials have been known to add a dash of protein to their predominantly herbivorous diets by horking down the occasional bird brain. Unconcerned with waste management, tree kangaroos generally discard the rest of the corpse after consuming the gray matter.

(More from Mental Floss: The stories behind 10 Johnny Cash songs)

2. Great tit (Parus Major)

The great tit's powerful beak is an excellent nut-smashing tool. It also doubles as a handy-dandy bat-skull-crusher. Seeds and insects are the favored cuisine...

A big chunk of the Sierra Nevada caught fracturing on video

If you like geology, you’re used to relying on an active imagination. Most geologic processes occur too slowly to see them play out for yourself. Many of the exceptions are dangerous enough that you might not want a front row seat or are rare enough that the odds of being there to witness them are disheartening. Sometimes, though, the Earth throws us a bone—or in this case, a gigantic slab of granite.

One interesting way that rocks weather and crumble apart is called “exfoliation.” Like the skin-scrubbing technique, this involves the outermost layers of exposed igneous or metamorphic bedrock sloughing off in a sheet. Over time, this tends to smooth and round the outcrop—Yosemite’s Half Dome providing a spectacular example.

We’re not entirely sure just what drives the peeling of an outcrop’s skin like this, but the classic explanation is that it’s the result of bringing rocks that formed at great pressure up to the surface. Once there, the outer layers can expand slightly, creating a physical mismatch with the layers below them.

tagged with: dust clouds, new born stars, star nursery, interstellar hydrogen clouds, n44 nebula, star cluster ngc 1929, supernovas, hrbstslr sbsblmc, astronomy images, outer space, hot young stars

Galaxies, Stars and Nebulae series An awesome photograph from deep space featuring a super bubble in the Large Magellanic Cloud, which is a small satellite of our Milky Way galaxy around 160000 light years from us.
The massive stars of this nebula produce intense radiation, expelling matter at high speeds, and race through their main stage finally to explode as supernovas. The stellar winds of charged hydrogen and other particles and the supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. Blue shows hot regions created by these winds and shocks, while red shows where the dust and cooler gas are found. Yellow regions show where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.

Merging Galaxies - The Antennae Galaxies Star Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: envelope sealer, stretch frame, awesome astronomy images, super star clusters, agmcssc, antennae galaxies, merging galaxies, best hubble photos, ngc4038 ngc4039, new born stars, star cluster formation, dust clouds

Galaxies, Stars and Nebulae series A stunning outer space picture featuring two merging galaxies, known as the Antennae Galaxies - NGC4038 and NGC4039. As these galaxies hurtle through each other, billions of new stars are forced to precipitate out of the gas and dust clouds by the bunching and heating that's caused by the massive gravitic interactions. These tend to occur in clusters, the brightest and most condensed of them being known as super star clusters.

Planets with oddball orbits like Mercury could host life

Mercury has an oddball orbit—it takes longer for it to rotate on its axis and complete a day than it takes to orbit the sun and complete a year. Now, researchers suggest photosynthesis could take place on an alien planet with a similarly bizarre orbit, potentially helping support complex life.

Helix Nebula, Galaxies and Stars Star Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: star nurseries, star clusters, galaxies, stars, astronomy, nebulae, helixneb, helix nebula, starfields, european southern observatory, eso, vista

Galaxies, Stars and Nebulae series A fantastic colour-composite image of the Helix Nebula (NGC 7293). It was created from images obtained using the Wide Field Imager (WFI), an astronomical camera attached to the 2.2-metre Max-Planck Society/ESO telescope at the La Silla observatory in Chile.

The blue-green glow in the centre of the Helix comes from oxygen atoms shining under effects of the intense ultraviolet radiation of the 120 000 degree Celsius central star and the hot gas.

Further out from the star and beyond the ring of knots, the red colour from hydrogen and nitrogen is more prominent. A careful look at the central part of this object reveals not only the knots, but also many remote galaxies seen right through the thinly spread glowing gas.
