Why do we have blood types?

"Isn't it amazing?" says Ajit Varki, a biologist at the University of California, San Diego. "Almost a hundred years after the Nobel Prize was awarded for this discovery, we still don't know exactly what they're for."

National Gay Blood Drive

Today is the National Gay Blood Drive, a campaign dedicated to bringing attention to the fact that the FDA still bans any men who have had sex with other men (MSM), at any time since 1977 from becoming blood donors.

Grow your own stem cells

In this month's issue of Nature, Haruko Obokata and colleagues have made a breakthrough in the field of stem cell research, where they describe a unique cellular reprogramming phenomenon in which skin and blood cells could be converted into stem cells without the need to physically manipulate the nucleus or over-express reprogramming genes. Rather, the researchers subjected them to stress "almost to the point of death", by exposing them to various events including trauma, low oxygen levels and acidic environments. One of these "stressful" situations was simply to bathe the cells in a weak acid solution for about 30 minutes. Within days, the scientists found the cells had not only survived but had also recovered by naturally reverting into a state similar to that of an embryonic stem cell. The research suggests human cells could in future be reprogrammed by the same technique, offering a simpler way to replace damaged cells or grow new organs for sick and injured people. [more inside]

"Especially with the country in great need of donation, science should speak louder than stigma in determining who can help."

Tainted: Why Gay Men Still Can't Donate Blood - "Since 1983, Food and Drug Administration (FDA) guidelines have disqualified men who have ever had sex with men (MSM) from donating blood... Uneven application of exclusion to at-risk individuals suggests that risk aversion disproportionately impacts MSMs. For example, a non-MSM individual who has had sexual contact with a commercial sex worker or HIV-positive partner is deferred for only twelve months... The fact that the U.S. upholds a lifetime ban on MSM donation while Australian policy allows MSM individuals to donate a year or less after contact reveals a glaring discrepancy. Both ethics and science point to a flaw in FDA policy. That I could have had sex with 365 partners this year and be a perfectly fine candidate for donating blood, while the MSM next to me wouldn't qualify, betrays a faulty line of logic." [more inside]

Blood and Fire

"Blood and Fire" is an episode written by David Gerrold for possible use on Star Trek: The Next Generation. The script was commissioned and written, but never actually filmed because certain studio executives had a negative reaction to its positive depiction of an openly gay couple. It was eventually adapted by Gerrold into a standalone novel. With Gerrold's permission, Carlos Pedraza rewrote Blood and Fire for the fan series Star Trek: New Voyages. Gerrold did a final draft polish and also directed the episode. The entire two part episode is available on You Tube: Part 1, Part 2 [more inside]

The Ban on Blood Donation

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]

28 Days Later...more stem cells!

Scientists have discovered that "endometrial regenerative cells" (ERC's) -- in other words, human menstrual blood -- contains stem cells. ERC-derived stem cells seem to have a number of superior traits to both bone marrow derived and umbilical cord derived stem cells, the previous gold standards: they can give rise to a variety of different cell lines without differentiation, they multiply more quickly than other stem cells, they are able to replicate more times without adversely mutating, and they apparently do not need to be closely genetically matched to the recipient. Now some women have even begun banking their menstrual blood to preserve their stem cells through a company called "C'Elle: Your Monthly Miracle" -- check out their FAQ and online video. This follows last May's announcement that menstrual blood derived cells can pretty much cure Duchenne Muscular Dystrophy in mice, a disease for which there is no current therapeutic treatment available.
