Retinal transplants bear threefold fruit
Darkfrog submitted, created time 3 weeks 6 days (www.nature.com)
A formerly clinically blind woman's vision improved from 20/800 to 20/160--from one-fortieth of ordinary vision to one-eighth--after receiving donated retina. Six months after the operation, the started noticing the pendulum in her grandfather clock. For years, she found that she could read large-print books and emails and returned to her hobbies, knitting and sewing. Now, six years after her operation, her vision is fading, but it is still better than it was before the operation 
When the past catches up with the present

Oversight committees face tough decisions after an analysis questions whether certain cell lines meet standards of informed consent. If not, then the number of stem cell lines that U.S. scientists may study with federal funding may drop from twenty-one to sixteen.
Consent issues restrict stem-cell use and research
sea-maid submitted, created time 2 months 1 week (www.nature.com)
Some researchers in Stanford University are told that around one-quarter of the human embryonic stem-cell lines eligible for U.S. government funding are now off-limits because of ethical concerns. The university is concerned that some of the women who donated the embyros that were used to generate the line might not have been fully informed of how they would be used.
The consent forms that the women signed were retrieved and it was found that none of them met Standford's guidelines exactly and some of them were way off the mark
Nature takes a look at in-vitro fertilization's past, present and future
Darkfrog submitted, created time 2 months 2 weeks (www.nature.com)
This article is a comprehensive look at the past and future of artificial babymaking. It covers IVF, the possible use of iPS to make gametes. It covers ethics, public relations, and economics...
The part that I like best? IVF has "gone as far as it can" with regards to what it can do, so the next focus is on making it cheaper. The article discusses the woman in a developing country who, on top of her own wishes for a family, faces discrimination for her infertility
Stem cell researchers face down stem cell tourism
sea-maid submitted, created time 3 months 3 weeks (www.nature.com)
"Stem cell tourism," in which people travel thousands of miles and pay thousands of dollars to receive unregulated care, is nothing new. Now, with more stem cell applications being pushed toward clinical trials, the international research community is stepping up.
Although some of the patients report positive results, the fact that they cannot describe their treatments in detail--or produce verifiable medical records--severely limits the research value (though not the human value) of their cases

Because there are challenging debates between those who argue that all research involving embryonic stem cells is immoral and those who see immense medical potential in this area of research, I have decided to include this article.
This study found that medical need dictates that the origin of human individuality must be defined with similar pragmatic precision. So a cell cannot have a soul.

A plan to hold a presidential debate on science and technology issues in Philadelphia, Pennsylvania, next week has failed. Now organizers hope to stage the event on May 9 in Oregon. But with candidates careful to avoid missteps, that plan faces tough odds.
Part human, part cow embryos made in UK
Sue Wu submitted, created time 6 months 5 days (www.telegraph.co.uk)
This is not a joke from April Fool's Day; it's real!
But it seems to come with some ethical problems.
Scientists at Newcastle University have created Britain’s first human-animal hybrid embryos for research by transferring the DNA from a human cell into a cow’s egg whose nucleus had been removed, it emerged on Tuesday night.
Putting Immunity in a Test Tube

To streamline vaccine research and hasten the eradication of global killers, such as AIDS, VaxDesign company has created a simulated human immune system, called the Modular Immune in Vitro Construct (MIMIC for short). The dime-sized immune systems can predict how humans will respond to new vaccines.
Ethical treatment of whole genome research participants

Recent technological developments have made it possible for scientists to sequence an entire human genome, but these advances may be a mixed blessing.
When Is Sedation Really Euthanasia?

Terminal sedation is the decision to keep dying patients, who cannot be made comfortable in any other way, unconscious until they die. But when is this the same as euthanasia?
Humans Marrying Robots? A Q&A with David Levy
sumsung submitted, created time 7 months 2 weeks (www.sciam.com)
Last year, David Levy published a book, Love and Sex with Robots, which marked a culmination of years of research about the interactions between humans and computers. His basic idea is that, for humans who cannot establish emotional or sexual connections with other people, they might form them with robots. The topic is ripe for ridicule: On the Colbert Report in January, host Stephen Colbert asked Levy, "
A drive to lower the incidence of multiple births in fertility treatments
Darkfrog submitted, created time 7 months 2 weeks (www.nytimes.com)
Doctors employing in vitro fertilization tend to implant several healthy embryos in the hopes that at least one will end up as a full-term healthy baby. However, this technique often leads to multiple births. Women carrying three or more children have a dramatically increased risk of health problems, premature birth and miscarriage, to the point where doctors often recommend "reducing," or selectively aborting one of the fetuses once it becomes apparent that triplets or more are on the way
Reviewer leaked Avandia study to drug firm
jane2007 submitted, created time 8 months 6 days (www.nature.com)
A peer reviewer for The New England Journal of Medicine (NEJM ) broke confidentiality and leaked a damaging report about the blockbuster diabetes drug Avandia to the drug's manufacturer weeks ahead of publication. The drug would increase the risk of heart attack.
Discovery in rat hearts could lead to tailored transplants
Darkfrog submitted, created time 8 months 3 weeks (www.nature.com)
A few years back, I described induced pluripotent stem cells as "the holy grail." This is what stem cell researchers were looking for: a way to produce rejection-proof cells specifically tailored to the patient's system. However, stem cells still can't be grown into organs all by themselves -- we can make liver tissue but we can't make a liver. They need a frame upon which to grow.
And some guys from the University of Minnesota just found out how to get one.
