Enzymes grow artificial DNA

In the news: "Enzymes grow artificial DNA" nature.com April 19, 2012 SL2411 Genetic engineering, conceptual artwork. DNA (deoxyribonucleic acid) molecule made of Lego representing scientists' ability to alter and rearrange an organism's genetic material. DNA is composed of two strands twisted into a double helix. Each strand consists of an outer sugar-phosphate backbone (white) with nucleotide bases attached (red, green, blue and yellow). The sequence of these bases forms the genetic code, determining each cell's structure, function and behavior. Inserting new DNA into a section of original DNA will alter the instructions from this region. Credit: Equinox Graphics / Photo Researchers, Inc.

Post-Prozac Nation

In the news:  "Post-Prozac Nation" by Siddhartha Mukherjee New York Times Magazine April 19, 2012 SF6032 Prozac molecules. Computer artwork of molecules of the antidepressant drug Prozac (fluoxetine hydrochloride). Atoms, represented as spheres, are color-coded: carbon (grey), hydrogen (white), fluorine (green), oxygen (red) and nitrogen (blue). Prozac inhibits the uptake of the chemical serotonin, a powerful brain chemical that is important in mood regulation. As well as depressive illnesses, Prozac is also used to treat other disorders, such as bulimia nervosa and obsessive-compulsive disorder. Antidepressant drugs usually take at least 10 days to have any beneficial effect. Credit: Phantatomix / Photo Researchers, Inc.

A Vaccine for Cancer?

In the news: "'Universal' cancer vaccine developed" by Richard Gray The Telegraph April 8, 2012 Death of a cancer cell (green). A buffy coat containing red blood cells, lymphocytes (orange) and macrophages (purple) is added to the bottom of the membrane. A group of macrophages identify the cancer cell as foreign matter and start to stick to the cancer cell, which still has its spikes. Photo magnification: 4000x.

The Iceberg Was Just the Tip of the Iceberg

In the news: "The Iceberg Was Only Part of It" By William J. Broad New York Times April 9, 2012 BR9652 The Titanic steamship was the largest ship ever built at the time. In 1912, the ship sailed from Southampton, England to New York City. On April 14th, the ship struck an iceberg near Grand Banks and sank the next day. Only about 700 people survived out of the roughly 2,200 passengers and crew. Colorization by: Jessica Wilson

Finding Phenotypes

Image
In the news: "Finding Phenotypes" by Edyta Zielinska The Scientist April 1, 2012 SA1716 Light micrograph of Caenorhabditis elegans, a soil-dwelling bisexual nematode worm which feeds on bacteria. A tendency to reproduce by self-fertilization (resulting in identical offspring), along with the short time taken to reach maturity, make this tiny worm an ideal subject for genetic research. Scientists have already drawn up a "wiring diagram" of its nervous system, studied the development of each of its 959 component cells and produced a map of its genes. Attempts are now being made to decode the genetic blueprint of C. elegans, to identify every one of the 100 million letters, or bases, in its genome. Nomarski illumination.

Prostate cancer cells, colored scanning electron micrograph (SEM). The nodular appearance of these cells is typical of cancer cells. The cells divide chaotically and may clump (as here) to form tumors, which often invade and destroy surrounding tissues. The prostate is a small gland found in men just below the bladder.
