Researchers at the University of Illinois at Chicago have discovered a chemical compound in male blue crabs that is not present in females -- the first time in any species that an entire enzyme system has been found to be activated in only one sex.--Marios F. Sardis 11:00, 28 August 2007
The human intestine is home to trillions of bacteria. Investigation of the colonization of the infant gut by these microorganisms is a prelude to understanding how they may act in both health and disease.. --Marios F. Sardis 19:00, 1 August 2007
Nobel laureate James D. Watson peered deep into his genome yesterday. And soon, anyone else interested in his genetic makeup will be able to do the same. . --Hartigan 10:00, 2 June 2007
The most common type of star in the Galaxy may be more hospitable to life than was previously believed, say astronomers who have calculated how much radiation planets orbiting such stars would receive. --Hartigan 10:00, 30 May 2007
According to the Nobel Foundation statutes, the Nobel Laureates are "to give a public lecture on a subject connected with the work for which the prize has been awarded." Watch live webcasts of the Nobel Lectures from Oslo and Stockholm, or the video on demand versions, available soon after the events. --Hartigan 20:00, 15 December 2006
I know this has nothing to do with Biology(sorry) but I feel it would be of enormous interest for many of you!It's really a great story! --Hartigan 12:00, 3 December 2006

When Norway’s museums authority called for ideas for an exhibition that engaged with contemporary societal debates, Geir Söli, head of exhibitions at Oslo’s Natural History Museum, had just the theme. He had been listening to a priest arguing on the radio that homosexuality is a sin and contrary to nature..--Hartigan 22:00, 28 October 2006
The trial in Libya of six medics accused of infecting children with HIV ends next week. With the defendants facing possible execution, Declan Butler asked AIDS experts to assess the case against them..--Hartigan 22:00, 28 October 2006
The battle of the sexes continues to rage — right down to the level of our genes. A gene has now been discovered that, when mutated, turns girls into boys. The finding advances, but also complicates, our understanding of how sex is determined by our genes.--Hartigan 14:30, 19 October 2006
This review briefly summarizes the biology of HSV-1, examines various strategies that have been used to genetically modify the virus, and discusses preclinical as well as clinical results of the HSV-1-derived vectors in cancer treatment.--Hartigan 19:30, 14 October 2006

NEW YORK (Reuters Health) - Patients on maximal suppression of HIV-1 continue to have viral reservoirs with high potential for replication in gut-associated lymphoid tissue (GALT).--Hartigan 11:00, 7 October 2006 (EDT)
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2006 to Roger D. Kornberg, Stanford University, CA, USA, "for his studies of the molecular basis of eukaryotic transcription".--Hartigan 16:00, 5 October 2006 (EDT)
The Nobel Assembly at Karolinska Institutet has decided to award The Nobel Prize in Physiology or Medicine for 2006 jointly to Andrew Z. Fire and Craig C. Mello for their discovery of "RNA interference – gene silencing by double-stranded RNA". --Hartigan 16:00, 5 October 2006 (EDT)
Researchers have come another step closer to understanding what made the influenza strain of 1918 virus so devastating. In this week's issue of Nature, a team of scientists describes for the first time what happens at the genomic level in animals infected with the killer virus. The infection rapidly turned on a wide range of genes involved in immune system activation and cell death, they conclude, bolstering the hypothesis that the greatest harm may not have been done by the virus itself, but by an over-reactive immune system. --Hartigan 13:00, 2 October 2006 (EDT)
Geobacter is capable of producing 3nm to 5nm nanowires. What material the nanowires are made of is not yet known, but the genetic code responsible for their creation is. Also, from Pacific Northwest National Laboratory: some bacteria are able to produce electrically conductive nanowires as small as 10 nanometers in diameter and hundreds of microns in length. --Ilya 18:12, 11 September 2006 (EDT)

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)
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)

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)
