It’s hard to believe, but this bushy, glowing object is a section of a ladybug leg. Ladybugs, also known as ladybirds, are readily available to either clear your gardens of aphids or make your wine taste really funny. It was photographed by Andrea Genre of the University of Turin, Italy.

Fuck you. Hounding my heels since I was a little kid. I’m a fucking adult and still can’t shake you, can’t grow out of you, can’t logic you away. This cycle is a bad one and I don’t need it right now. You’re poisoning my relationship, hindering my education, making me doubt myself, keeping me exhausted after 12 hours of sleep, won’t let me have a moment’s peace without hate and anger, keeping me afraid of my friends, afraid of strangers, afraid of myself.

I hate you more than I hate myself, and that is saying something.

So Fuck You.

Still Active Spokes

The ghostly spokes in Saturn’s B ring continue to put on a show for the Cassini spacecraft cameras in this recent image. The spokes, believed to be a seasonal phenomenon, are expected to disappear as Saturn nears its northern hemisphere summer. Scientists continue to monitor the spokes to better understand their origin and evolution.

The small moon Atlas also appears here barely visible in between the A ring and the F ring, which is the thin ring located furthest from Saturn, as the fainter dot close to the A ring. Atlas is closer to the bottom of the image. A bright star also appears in the gap between the two rings, and there are six other stars visible (one through the C ring, near the planet).

This view looks toward the unilluminated side of the rings from about 49 degrees below the ringplane. The image was taken in visible light with the Cassini spacecraft wide-angle camera on Dec. 20, 2012.

The view was obtained at a distance of approximately 840,000 miles (1.4 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 105 degrees. Image scale is 48 miles (77 kilometers) per pixel.

Zebrafish Eye

As light enters the vertebrate eye, it must travel through all of the retinal layers before reaching the light-sensitive rods and cones (purple). To minimize the diffusion, or scattering, of incoming light, the Müller glia (orange) collect and funnel the light directly to the photoreceptors. Researchers equate Müller cells to a fiber optic plate: a “zero-length window” that can transmit an image without using a lens. The Müller cells, however, are more efficient in the collection of light than man-made optical fibers because of their unique funnel shape. Engineers hope to replicate Nature’s design in various pieces of sensing equipment.

The Immortal Jellyfish

While the humans have been looking for the elixir of life throughout every period of history, it appears that there is one species of jellyfish that are actually immortal. Turritopsis nutricula is able to transform its cells from mature state back to immaturity, in other words – back to youth. The medusa leads a regular cycle of life, but after maturing and mating, it reverts back to its initial state – a polyp colony.

The process is referred to as “transdifferentiation”, and it basically makes the jellyfish unable to die. The bell-shaped immortal jellyfish measures up to a maximum of about 4.5 millimeters (0.18 in) and is about the same in its length and width. Originating in the Caribbean, it has now spread worldwide, and the discovery of its unique ability has heated up many discussions among the scientists. Some claim that their mystery is soon to be solved and applied to humans, while others only expect it to improve the quality of life at our final stages.

This is the alarm jellyfish (Atolla Wyvillei) - and it has a rather unique defence mechanism. When the alarm jellyfish is attacked, it flashes brightly using bioluminescence in an attempt to attract other animals. The idea is to encourage confusion and fights between predators, while the jellyfish can swim away.

Read of the day: When the Dutch cloth merchant Antonie van Leeuwenhoek looked at a drop of pond water through his home-made microscope in the 1670s, he didn’t just see tiny ‘animals’ swimming in there. He saw a new world: too small for the eye to register yet teeming with invisible life. The implications were theological as much as they were scientific.

Invisibility comes in many forms, but smallness is the most concrete. Light ignores very tiny things rather as ocean waves ignore sand grains. During the 17th century, when the microscope was invented, the discovery of such objects posed a profound problem: if we humans were God’s ultimate purpose, why would he create anything that we couldn’t see?

The microworld was puzzling, but also wondrous and frightening. There was nothing especially new about the idea of invisible worlds and creatures — belief in immaterial spirits, angels and demons was still widespread. But their purpose was well understood: they were engaged in the Manichean struggle for our souls. If that left one uneasy in a universe where there was more than meets the eye, at least the moral agenda was clear. (via Philip Ball – Microscopic worlds)
