Totally wicked queeah amounts of old Simon & Garfunkel records, brah.

The DNA Replication Complex, an assembly of proteins that synthesizes new DNA before cell division. It consists of Helicase, Primase, Single-strand binding proteins, and DNA polymerase III. Because DNA strands can only be copied in one direction, the complex must pull out loops of one strand and replicate it in fragments. At this moment there are hundreds of trillions of these molecular machines in constant activity within your body.
In humans, this process is happening at the staggering speed of 3,000 DNA bases per minute. And in bacteria? Would you believe 30,000 bases per minute?!? That’s 500 nucleotides per second!!!
The Peacock spider or Gliding spider (Maratus volans) is a species of jumping spider.
Octavius Pickard-Cambridge noted in his original description that “it is difficult to describe adequately the great beauty of the colouring of this spider”.
The red, blue and black colored males have flap-like extensions of the abdomen with white hairs that can be folded down. They are used for display during mating: the male raises his abdomen, then expands and raises the flaps so that the abdomen forms a white-fringed, circular field of color. The species, and indeed the whole genus Maratus have been compared to peacocks in this respect. The third pair of legs is also raised for display, showing a brush of black hairs and white tips. While approaching the female, the male will vibrate his abdomen while waving raised legs and tail, and dance from side to side.
Both sexes reach about 5 mm in body length. Females and immatures of both sexes are brown but have colour patterns by which they can be distinguished from related species. [ read more ]

The Sharpest View of The Sun
Here is one of the sharper views of the Sun ever taken. This stunning image shows remarkable details of a dark sunspot across the image bottom and numerous boiling granules which appear like kernels of corn across the top. Taken in 2002, the picture was made using the Swedish Solar Telescope operating on the Canary Island of La Palma.
