Galaxy cluster formation. Supercomputer model of the formation of galaxies and clusters of galaxies from the contraction of a homogeneous cloud (left). Over time, the dark matter in the cloud coalesces due to mutual gravitational attraction. This leads to the formation of dense pockets in which stars (yellow) can form. Dark matter is a form of matter that does not emit radiation, making it hard to detect. It is only detectable by its gravitational effects. Models such as this can help to estimate the amount of dark matter in the universe by seeing whether they produce results that look like the real universe.

Acute Lymphoblastic Leukemia - Hope in new Cell Therapy

Color enhanced transmission electron micrograph of cancerous white blood cells (orange) in leukemia. Leukemia is a malignant disease in which bone marrow and other blood-forming organs overproduce certain types of white blood cells. Whereas normal white blood cells play a protective immune-response role, leukemic white blood cells are immature and abnormal. they suppress normal blood cell production resulting in anemia, poor blood clotting, and a weakened immune system. Treatment includes anti-cancer drugs and bone marrow transplants.

BT5738 The Malaysian Orchid Mantis, Hymenopus coronatus, inhabits rainforests of southeast Asia and the Indo-Australian Archipelago. They have a color and body plan designed to blend them in with the flowers they typically live on. This small predator sits in wait within a flower, sometimes an orchid flower, for a small insect to approach. They grab potential pray items with their grappling arms equipped with long spines. The spines hold onto prey items and make prey handling an easier prospect. This specimen was photographed in Thailand, 2011.

Astronomy Picture of the Day - Water Bear!

 In the news:
March 6, 2013



Water bear (Macrobiotus sapiens) in moss. Color enhanced scanning electron micrograph (SEM) of a water bear in its active state. Water bears (or tardigrades) are tiny invertebrates that live in aquatic and semi-aquatic habitats such as lichen and damp moss. They require water to obtain oxygen by gas exchange. In dry conditions, they can enter a cryptobiotic state of desiccation, known as a tun, to survive. In this state, water bears can survive for up to a decade. This species was found in moss samples from Croatia. It feeds on plant and animal cells. Water bears are found throughout the world, including regions of extreme temperature, such as hot springs, and extreme pressure, such as deep underwater. They can also survive high levels of radiation and the vacuum of space. Magnification: x250 when printed 10cm wide.

Forensic Science Images, and More!

This new image collection
is so good, it's criminal!
...Or is it?...




 A tiny drop of blood. A strand of hair. Maybe a muddy boot print, or a cigarette butt carelessly tossed away. These are some of the clues that can solve crimes. Forensic scientists interpret these clues using their expertise in fields such as entomology, pathology, dentistry, toxicology, and psychology to reconstruct what happened and identify "who-done-it!"
