The Inner Life of the Cell is a 3D animation created by XVIVO for students in Harvard's Molecular and Cellular Biology program. Other animations are on XVIVO's website (from the "Animation" tab at the bottom). --Ilya 02:45, 2 September 2006 (EDT) Involvement of intracellular free Ca2+ in enhanced release of herpes simplex virus by hydrogen peroxide.It was reported that elevation of the intracellular concentration of free Ca2+ ([Ca2+]i) by a calcium ionophore increased the release of herpes simplex virus type 1 (HSV-1). Freely diffusible hydrogen peroxide (H2O2) is implied to alter Ca2+ homeostasis, which further enhances abnormal cellular activity, causing changes in signal transduction, and cellular dysfunction. Whether H2O2 could affect [Ca2+]i in HSV-1-infected cells had not been investigated..--Hartigan 10:30, 01 September 2006 (EDT) No vaccine against HIV yet-are we not perfectly equipped?Enormous effort has been devoted to the development of a vaccine against human immunodeficiency virus (HIV). But it is proving to be an unprecedented challenge to create an effective vaccine mainly due to the high genetic variability of the virus and the necessity of cytotoxic T lymphocytes (CTL) for containing the infection.--Hartigan 10:30, 01 September 2006 (EDT) Controling AIDS virusMontreal Researchers Make A Major Strategic Breakthrough In Controling The AIDS Virus. --Hartigan 23:00, 29 August 2006 (EDT) FDA approves viruses as food additive: A mix of bacteria-killing viruses can be safely sprayed on cold cuts, hot dogs and sausages to combat common microbes that kill hundreds of people a year, federal health officials said in granting the first-ever approval of viruses as a food additive. --Ilya 22:02, 18 August 2006 (EDT) Information transmission rate from eye to brain measured: with about 1,000,000 ganglion cells, the human retina would transmit data at roughly the rate of a 10Base-T Ethernet connection, or 10 million bits per second. --Ilya 17:32, 31 July 2006 (EDT) Are Nanobacteria Making Us Ill? Nanobacteria are said to be cell walled microorganisms with a diameter well below the generally accepted lower limit (about 200 nanometres) for bacteria. --Ilya 01:22, 13 May 2006 (EDT) Nanobacteria – propagating calcifying nanoparticles a 2006 paper in Letters in Applied Microbiology. --Ilya 16:04, 5 June 2006 (EDT) Power Up With Magnetic Bacteria Using magnetic bacteria to produce electricity --Ilya 19:39, 12 May 2006 (EDT) A New Twist on DNA DNA origami? --Jennyn 10:52, 27 April 2006 (EDT) Giant Stuffed Microbes The cutest microorganisms ever! --Jennyn 13:34, 20 April 2006 (EDT) New pathogenic bacterium pinpointed Granulobacter bethesdensis, named after the disease (chronic granulomatous disease) and location (Bethesda, Maryland) in which it was found. Nature News, April 14, 2006 --Jennyn 10:25, 18 April 2006 (EDT) IBM Creates Ring Oscillator on a Single Nanotube Ilya 15:50, 29 March 2006 (EST) via Jasonk Spore by Maxis - link to google video The first synthetic biology game? --Ilya 16:47, 16 March 2006 (EST) This is going to be the best, most addicting game ever! --Jennyn 16:58, 16 March 2006 (EST) 'DNA' nebula found in Milky Way Cosmic nebulae usually look like blobs in space, but astronomers using the Spitzer Space Telescope reported on Wednesday they have found a nebula twisted like the double helix of DNA. --Ilya 16:29, 16 March 2006 (EST) Craig Venter's Synthetic Genomics plans to "program cells" to produce hydrogen
