SH7063 Giant tube worms (Riftia pachyptila) on a hydrothermal vent. These animals inhabit a tube (white), from which they extend feathery red plumes. The plumes take in chemicals and release waste. The chemicals are passed to colonies of symbiotic bacteria that live inside the worm, which convert the chemicals into nutrients on which the worm feeds. The worms are usually found near hydrothermal vents (black smokers), and are extremely resistant to the heat associated with the vents. Photographed deep in the Pacific Ocean. Credit: C.

Terrorized by the Flu?

Avian influenza virus particles. Colored transmission electron micrograph (TEM) of a H5 strain of influenza virus type A. All five H5 strains (H5N1, H5N2, H5N3, H5N8 and H5N9) cause bird flu. The particles (red) have an enveloped outer coat, or capsid. The capsid contains hemagglutinin (H) and neuraminidase (N) proteins, which allow the particles to enter the host's cells and reproduce.  Magnification: x53,000 when printed 10 centimeters wide.

Change at the Core

In the news:  "Metal undergoes novel transition under extreme pressure" BBC News online December 20, 2011

SM8688 Earth layers, computer artwork. The external layer shows the Earth's surface topography and atmosphere, including land, water and clouds. This surface layer extends downwards for around 35 kilometers as the rocky crust. The mantle (red) is a viscous layer of rocks under high pressures and temperatures, extending downwards to a depth of around 2890 kilometers. The outer core (yellow) is a liquid layer of iron and nickel, around 2260 kilometers thick. The inner core (top) is a liquid sphere of a iron-nickel alloy, with a radius of 1220 kilometers.

Norovirus Vaccine

In the news: "Prevention: Trial Vaccine for Norovirus Shows Promise" By Nicholas Bakalar New York Times online December 12, 2011
Norovirus particles. Colored transmission electron micrograph (TEM) of norovirus particles (purple). Norovirus is a genus of RNA (ribonucleic acid) viruses (of the family Caliciviridae), which cause about half of all gastroenteritis cases around the world. The disease is characterized by nausea, vomiting, diarrhea and abdominal pain. The diarrhea results in fluid loss and dehydration, which may become life-threatening in the young, the elderly, and the immunocompromised if not treated promptly.

A Hairy Bed Bug Situation

In the news: "Hairy limbs keep bed bugs at bay" BBC News online December 14, 2011

SA4667 Colored scanning electron micrograph (SEM) of bed bugs mating. Bed bugs (Cimex lectularius) are blood sucking insects, so called because they live in the beds of humans. The male (above) punctures the body wall of one of the female's abdominal segments and deposits his sperm in a sac. This is called traumatic insemination.

On the Origin of the Theory of Evolution

In the news: "Shipping Timetables Debunk Darwin Plagiarism Accusations" By Philip Ball December 12, 2011
BT3863 Charles Robert Darwin (1809-1882) was an English naturalist. He established that all species of life have descended over time from common ancestry, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection. His seminal works: On the Origin of Species (1859) his theory with compelling evidence for evolution. The Descent of Man (1871) he examined human evolution and sexual selection and The Expression of the Emotions in Man and Animals (1872) one of the most enduring contributions from 19th century psychology.

DisCERNing the Higgs boson

In the news: "LHC: Higgs boson 'may have been glimpsed'" By Paul Rincon
BBC News online December 13, 2011
View of the Central tracking Chamber of the Collider Detector at Fermilab (CDF). This device saw the top quark. CDF is an experiment at Fermilab, which is currently home to the world's most powerful particle accelerator called the Tevatron. The Tevatron accelerates protons and antiprotons close to the speed of light, and then makes them collide head-on inside the CDF detector. The CDF detector is used to study the products of such collisions; by doing this we try to reconstruct what happened in the collision and ultimately try to figure out how matter is put together and what forces nature uses to create the world around us.

Anomalocaris - Cambrian Predators


Reconstruction of the problematic animal, Anomalocaris canadensis, from the Middle Cambrian Burgess Shale of British Columbia. By far the largest animal in the Burgess Shale fauna this creature of unknown affinity reached lengths of half a meter. Anomalocarids have been discovered in China, Greenland, Australia, and North America.

In the news: "An eye-opening fossil" By Matt Kaplan
December 7, 2011

Reconstruction of the Anomalocaris sp., the Middle Cambrian Chengjiang fauna of China. Although similar in most respects to Anomalocaris canadensis to the Burgess Shale, the Chinese specimens show two long spines projecting from the tail. It is possible that the spines simply have not yet been recognized in the Burgess Shale specimens. Anomalocaris has experienced a long history of misinterpreted isolated parts. The front claws were originally described as shrimp, the circular mouth plate as a jellyfish,…

Happy Birthday, Heisenberg - For Certain.

BE9320 German physicist Werner Heisenberg (1901-1976), one of the founders of quantum mechanics and head of Germany's nuclear energy program. His role in this capacity is subject to much debate, with some believing he covertly tried to thwart Germany's program to develop nuclear weapons. He discovered the Heisenberg uncertainty principle, which is now one of the central principles of modern physics.  Credit:Photo Researchers
