It concludes that the so-called stimulus-triggered acquisition of pluripotency (STAP) stem cells, as well as the chimeric mice and teratomas supposedly derived from those cells, "all originated in cultures contaminated with (embryonic stem) cells, a fact that refutes all of the main conclusions of the two papers" that reported the the supposed breakthrough method of reprogramming adult cells. Those two papers, an article and a letter, appeared online in Nature on 29 January.

Although there have been more than two thousand studies documenting that GMOs do not pose an unusual threat to human health, questions about the safety of genetically modified foods remain in the minds of many consumers.

It is, when you think about it, sort of weird that nearly all mammals lose the ability to digest milk early in life. The Class Mammalia is, after all, defined by the gland that produces this life-giving fluid-supplier not only of necessary nutrients but also of water and molecules that protect against continual assaults from invading organisms.

Introducing your students to Scratch will provide your students with hands-on opportunities to think creatively, solve problems and work collaboratively.  Scratch is a visual programming platform created at the Massachusetts Institute of Technology (MIT) by the Lifelong Kindergarten Group at the MIT Media Lab and is available to all users free of charge. This web-based tool is designed for students ages 8 to 16 but used by people of all ages.  With Scratch, you can program your own interactive stories, games, and animations - and share your creations with others in the online community.

 Trilobites may be the archetypal fossils, symbols of an archaic world long swept beneath the ruthless road grader of time. But we should all look so jaunty after half a billion years.

One of these days, there could well be a simple blood test that can help diagnose and track cancers. We aren't there yet, but a burst of research in this area shows we are getting a lot closer.

Damaged leg muscles grew stronger and showed signs of regeneration in three out of five men whose old injuries were surgically implanted with extracellular matrix derived from pig bladder, according to a new study. Early findings are from a human trial of the process as well as from animal studies.

The club, which has about 20 members, is researching the culture and regrowth of methanotrophic bacteria, using a wide variety of experiments and individual projects. The students meet every Thursday with their advisor, Michael Ralph, and they also work during their own time.

Overview of genetic engineering and business assessment of scientific feasibility.  Good overview of past gene therapy attempts.

Researchers have for the first time used electrical pulses delivered from a cochlear implant to deliver gene therapy, thereby successfully regrowing auditory nerves. The research also heralds a possible new way of treating a range of neurological disorders, including Parkinson's disease, and psychiatric conditions such as depression through this novel way of delivering gene therapy.

Promising animal model work utilizing gene therapy.

Liver buds and brain organoids are among this year's life-saving advances in growing spare human parts.

Phys.org) -Scientists at the University of Virginia School of Medicine have overcome one of the greatest challenges in biology and taken a major step toward being able to grow whole organs and tissues from stem cells. By manipulating the appropriate signaling, the U.Va. researchers have turned embryonic stem cells into a fish embryo, essentially controlling embryonic development.

When you look at yourself in the mirror you may ask, 'How, given that all the cells in my body carry the same DNA, can my organs look so unlike and function so differently?' With the recent progress in epigenetics, we are beginning to understand. We now know that cells use their genetic material in different ways: genes are switched on and off, resulting in the astonishing level of differentiation within our bodies.

or more than a decade scientists have been saying that a genomic revolution will transform medicine, making it possible to scan all of a person's DNA to predict risk and customize medical care. Well, we've got the machines. Where's the revolution? Getting closer, say researchers at Stanford University, who tested the technology on 12 people. But not quite ready for every doctor's office.

Every year, it inflicts between 250,000 and 500,000 helpless and malnourished young people with early-life blindness. And in half of those cases, it also brings death, according to the World Health Organization. Vitamin A deficiency also puts pregnant women at risk. It's rare in developed countries, but the goal of completely eradicating vitamin A deficiency - mostly in Africa and Southeast Asia - remains unmet. Scientists are now working to genetically engineer "super" bananas that are fortified with crucial alpha- and beta-carotene, which the body converts to vitamin A.

 A team of scientists has announced that the age of the synthetic chromosome is upon us, as a study published in Science today reveals how the group was able to construct a yeast chromosome from scratch - an experiment that allowed the team to make fully functional "designer yeast."
