The committee took the unprecedented step of recommending that some details of these biological studies [be] kept from the public, so that no one could use them as recipes for new bioweapons. [more inside]

Editors of the journal Science have asked the co-authors of a 2009 paper that linked chronic fatigue syndrome to a retrovirus called XMRV to voluntarily retract the paper. Science editor-in-chief Bruce Alberts and executive editor Monica Bradford cited concerns about the validity of the findings, saying other scientists hadn't been able to replicate them, among other reasons.

Could the three established domains of life - eukaryotes, bacteria and archaea - be joined by a fourth?

In the 1940s Barbara McClintock discovered the remarkable phenomenon of mobile genetic elements, or transposons: parasitic DNA that makes up a significant fraction of the human genome. (Here is a video segment about McClintock: Part 1 & 2.) The discovery remains highly important: we now know that transposons play a role in driving genome evolution. Where do they come from? A compelling hypothesis is that some evolved from viruses.

Now a marine biology group at UBC has found a virus whose closest genetic relative is a type of transposon. (The paywalled paper's abstract is here.) But that is not even the interesting part. [more inside]

The UN's FAO (Food and Agriculture Organisation) have announced that they believe rinderpest, an frequently fatal viral disease that affects livestock and wild ruminants, to have been eliminated. This is only the second virus, after smallpox, to have been wiped out. The BBC and the Guardian discuss the story in brief, and Science has a slightly more in-depth look at it. The FAO themselves have put up an interesting history of the disease and its treatment.

Are the Rules That Determine Who Can Donate Blood Discriminatory? Canadian AIDS researchers Dr. Mark Wainberg and Dr. Norbert Gilmore say that while the ban on blood donation from men who have sex with other men may have been ethically and scientifically justified in the 1980's, it no longer makes sense. (CMAJ.) Even though the US FDA reaffirmed their long-standing ban in 2007, they plan to revisit the policy in June. [more inside]

A German researcher accidentally jabbed her finger with a hypodermic loaded with the deadly Ebola virus. 48 hours later, she was injected with an untested, experimental vaccine, developed by an international team of virologists and biologists. Though she may never have been infected, she was certainly in danger; in 2004, a similar incident caused the death of a Russian scientist at a former Soviet biological weapons lab.

Darwin's Surprise. "There may be no biological process more complicated than the relationships that viruses have with their hosts. Could it be that their persistence made it possible for humans to thrive?" [Via Disinformation.]

Dr. Stephen Lanka claims that H5N1 doesn't exist. Or AIDS. Or disease-causing viruses in general. "In humans, in the blood or in other bodily fluids, in an animal or in a plant there never have been seen or demonstrated structures which you could characterize as bird flu viruses or flu viruses or any other supposedly disease-causing virus. The causes of those diseases which are being maintained to be caused by a virus, also those in animals, which can arise quickly and in individuals either one after the other or several at the same time, are known since a long time back. However much you stretch things in biology, there is simply no place for viruses as the causative agents of diseases. Only if I ignore the findings of Dr Hamer’s New Medicine, according to which shock events are the cause of many diseases, and the findings of chemistry on the effects of poisonings and deficiencies, and then if I ignore the findings of physics about the effects of radiation, then there is a place for imaginings such as disease-causing viruses."

A monstrous discovery suggests that viruses, long regarded as lowly evolutionary latecomers, may have been the precursors of all life on Earth. "We haven't even begun to scratch the surface. The numbers are mind-boggling. If you put every virus particle on Earth together in a row, they would form a line 10 million light-years long. People, even most biologists, don't have a clue. The general public thinks genetic diversity is us and birds and plants and animals and that viruses are just HIV and the flu. But most of the genetic material on this planet is viruses. No question about it. They and their ability to interact with organisms and move genetic material around are the major players in driving speciation, in determining how organisms even become what they are."

a) A virus is a form of life.
b) Scientists 'assemble' a virus in vitro
c) Man has power to create life.

Discuss.

The Big Picture Book of Viruses is "intended to serve as both a catalog of virus pictures on the Internet and as an educational resource to those seeking more information about viruses. To this end, it is intimately linked to All the Virology on the WWW, and our collection of Virology Courses and Tutorials." Interesting electron micrographs include pictures of Marburg and Ebola viruses and T-4 like phages. Once a bio geek, always a bio geek. And for some other information about why viruses always matter see The 1918 Influenza Pandemic (sorry the page design sucks but it's a good read) and The American Experience: Influenza 1918. Are you sure that runny nose is just allergies?

Ebola is for wimps! Some Australian scientists were trying to come up with a mouse contraceptive vaccine, for use in pest control. And they succeeded. Unfortunately, the virus they created works by killing mice before they can breed, and killing them very very well. Oh, and it's extremely vaccine-resistant: 100% death without vaccine, 50% with. And any kid with a Li'l Johnny Gene Engineering Kit could conceivably make a human version. Anyone got some smallpox virus laying around?

Today is World AIDS Day, and to commemorate this event (and the day without art and day without weblogs), I'll be posting AIDS/HIV-related links and I ask you all to do the same. A good information resource for today is the CDC's FAQ on AIDS. And I bet you've never seen the virus' life cycle before.
