Rhnull blood was first described in 1961, in an Aboriginal Australian woman. Until then, doctors had assumed that an embryo missing all Rh blood cell antigens would not survive, let alone grow into a normal, thriving adult. By 2010, nearly five decades later, some 43 people with Rhnull blood had been reported worldwide.

Simple new invention seals gunshot wounds in 15 seconds. (SLPopSci)
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]

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" 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]

Are the Rules That Determine Who Can Donate Blood Discriminatory?

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.
