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]

Dr. Jörg C. Gerlach
has developed a new device for applying a regenerative skin and stem cell slurry onto burn victims in an airbrush-like spray - providing astounding results
in mere days. (Warning - mildly graphic images of severe burns being remedied with SCIENCE!)

Grow your own spare parts.
At last we're regenerating properly. Scientists took stem cells from patients fat tissue, cultivated bone cells from them, crafted a nice comfy titanium cage where to grow and put the cage into man's abdomen. After 9 months, install new upper jaw.

Is Your Baby Gay?
Southern Baptist theologian Albert Mohler has come out to support stem cell research: If a biological basis [for homosexuality] is found, and if a prenatal test is then developed, and if a successful treatment to reverse the sexual orientation to heterosexual is ever developed, we would support its use as we should unapologetically support the use of any appropriate means to avoid sexual temptation and the inevitable effects of sin.

Congressman dies of rare disease
Congressman Bob Matsui, who was recently elected to a 14th term in Congress, has died due to a rare stem cell disease. Matsui, who was one of the leading opponents of President Bush's plan to eliminate Social Security, was the ranking Democrat on the Congressional subcommittee on Social Security.

Controversial new bill
to lay out reproductive technology guidelines. Canadian version of this battle doesn't seem to feature as many religious wackos. It's just not as fun without them.

Bush and Pro-Lifers call for complete ban on any clone or stem cell research.
The movement for a ban got a significant boost Tuesday when Sen. Bill Frist, R-Tenn., said he would support the cloning ban legislation, which the Senate is expected to debate in the weeks ahead. Though not a surprise, the announcement from Frist, a heart-transplant surgeon, is important because his views on medical topics are respected by many in Congress.
"Many are overpromising on the science" benefits that are possible from cloning, Frist told reporters. He also said creating a human embryo "for reason of experimentation leads to destruction of that embryo and to me that is morally unacceptable."
