In a groundbreaking study, researchers have successfully developed a method that could lead to unprecedented advances in computer speed and efficiency.
There have been 39 womb transplants using a live donor, including mothers donating their womb to their daughter, resulting in 11 babies.
But the 10 previous transplants from a dead donor have failed or resulted in miscarriage.
In this case, reported in The Lancet, the womb donor was a mother of three in her mid-40s who died from bleeding on the brain.
A team of doctors in Brazil have announced a medical first that could someday help countless women unable to have children because of a damaged or absent uterus. In a case report published Tuesday in the Lancet, they claim to have successfully helped a woman give birth using a transplanted uterus from a deceased donor.
According to the report, the team performed the operation on an unnamed 32-year-old woman in a Brazilian hospital in September 2016. The woman had been born with a rare genetic condition that left her without a uterus, known as Mayer-Rokitansky-Küster-Hauser syndrome, but she was otherwise healthy. The donor was a 45-year-old woman who had suddenly died of stroke; she had had three successful pregnancies delivered vaginally in the past.
The Food and Drug Administration on Monday took an unconventional approach to approving a new cancer drug.
The drug, Vitrakvi, was developed by Loxo Oncology. It’s the company’s first drug to get approved.
For at least the last 10 million years every yeast cell of the sort used to make beer or bread has had 16 chromosomes. But now—thanks to CRISPR technology and some DNA tinkerers in China—there are living yeast with just one.
Genome organizer: We humans have our genes arranged on 46 chromosomes, yeast use 16, and there’s even a fern plant with 1260 of them. That’s just the way it is. And no one is quite sure why.
The big one: Do we really need so many chromosomes? That’s what Zhogjun Qin and colleagues at the Key Laboratory of Synthetic Biology in Shanghai wanted to know.
Conditions encountered in the womb — when the embryo consists of only about 100 cells — can have life-long impact on health. Scientists previously assumed that this is because embryos respond to adverse conditions by programming their gene expression. Now an international team of researchers at the Leiden University Medical Center, Wageningen University and Research, Lund University, Columbia University Mailman School of Public Health in New York propose a radically different alternative. Rather than being programmed by the environment, random differences in gene expression may provide some embryos with a survival advantage, in particular when conditions are harsh. By studying DNA methylation, an important mechanism to control gene activity, the researchers found that a specific part of the DNA methylation pattern was missing among famine-exposed individuals. The findings are published in the journal Cell Reports.
A blood test can detect cancer within just 10 minutes, scientists have found, raising hopes that hard-to-spot diseases could be picked up early when treatment is most effective.
Currently doctors use symptoms and a raft of tests and biopsies to determine if cancer is present which can sometimes take months.
The new method from the University of Queensland looks for differences in the genetic code of cancerous and healthy cells.
Who isn’t interested in new ways to apply stem cell therapy these days?
Speaking of, have you heard about the scientists in Philadelphia, PA, who have been injecting stem cells directly into the spinal cords of medically brain-dead people in order to revive them?
In a page taken from Mary Shelley’s Frankenstein, the idea of “bringing people back from the dead” is a little too much like “playing God” for some critics to appreciate.
