Genetic engineering makes pig organs ready for humans at last?
sea-maid submitted, created time 1 day 15 hours (www.newscientist.com)
In the not too distant future, a person in need of a heart transplant could be offered a pig's organ. That's the hope of a group that met in China last week to agree global guidelines for the first clinical trials of "xenotransplants."
There have been some serious problems that scientists have had to overcome. For example, porcine endogenous retroviruses, or PERVs, are one major concern. These are chunks of viral DNA incorporated into the pig genome. There are fears that these viruses could reawaken if they are transported into an unfamiliar body 
Spanish scientists create extra-long-lived mice

Spanish scientists have created "super-mice" that are cancer-resistant and live up to forty percent longer, media reported Friday.
The mice were subjected to genetic engineering by researchers from the cancer research centre CNIO and Valencia University.
The key to the experiment was an enzyme called telomerase, which lengthens chromosome ends known as telomeres.
Telomerase allows cells to keep dividing and is believed to increase longevity, but it also heightens the risk of cancer
Are vertical farms the next necessary step in agriculture?
Darkfrog submitted, created time 2 months 13 hours (www.sciam.com)
Scientific American here highlights urban farming. The idea is that we spend all this time, water and energy not only growing and fertilizing plants the old-fashioned way but then transporting the food products all the way from the farms to the cities, where most of the people live and where--by 2050, a whole lot more people are going to live.
The article describes growing fruits and vegetables inside tall glass buildings like some kind of modern-day hanging gardens (I wonder if they give +2 happy faces like in Civilization). We've got construction and glassmaking technology

Researchers from Harvard have found that using adenoviruses to reprogram cells can avoid some of the risk of making induced pluripotent stem cells. Instead of integrating into the host cell's DNA, the adenoviruses express the genes themselves.
So far, the experiments have only been successful in mouse tail and liver cells, which are much less hard to work with than primate cells and tissues. In addition, the overall success rate is much lower than that of integrating virus methods, reprograming cells only 0.0001% to 0.001% of the time
FDA releases guidelines for genetically modified animals

The path from the lab to the marketplace for genetically modified cows, pigs and chickens has been clearly spelled out for the first time.
On September 18, the U.S. Food and Drug Administration released a draft of regulations for approving engineered animals for commercial use. The draft is freely available and open for public comment until November 18...
Turning Bacteria into Plastic Factories
jerry submitted, created time 2 months 1 week (www.sciam.com)
Plastics are one of the most versatile and useful things that can be made from expensive fossil fuels. ...except as of now, it's "that can be made from expensive fossil fuels and genetically engineered E. coli." A new company has found a way to produce polymers from genetically engineered microbes that feed on sugars, replacing fossil-fuel based processes.
The plastic in question is called butanediol, and the process has been in the works for some time. The trick was getting the bacteria to tolderate high levels of butanediol in the water. It's usually toxic.

Genetically engineered tobacco plants used to grow anti-lymphoma vaccine
Darkfrog submitted, created time 4 months 1 week (www.sciam.com)
Reports in the Proceedings of the National Academy of Sciences report that an experimental vaccines has triggered the immune systems of eleven (out of sixteen) patients to attack their tumors. The patients are afflicted with what is called follicular B-cell lymphoma. Dangerous side effects? None.
The interesting part? The vaccine was grown courtesy of some genetically engineered tobacco plants.
Of course, all of the patients were also receiving chemotherapy at the time, so it may be difficult to tell which results may be attributed to the vaccine itself

First GM human embryo is created!
Sue Wu submitted, created time 6 months 2 weeks (www.timesonline.co.uk)
Scientists have created what is believed to be the first genetically modified (GM) human embryo.
A team from Cornell University in New York produced the GM embryo to study how early cells and diseases develop. It was destroyed after five days
Leaf clippings as protein factories
kavin submitted, created time 7 months 1 day (www.sciencenews.org)
Traditionally, if researchers want to produce some proteins such as vaccinum，they need to develop a genetically modified plant first and getting government approval can take years. This new technique could induce plant leaves to mass-produce custom proteins in a matter of weeks. The plant cells could make virtually any kind of protein, including antigens for rapid production of vaccines against new viruses. Best of all, because this does not involve genetically engineering the entire plant, the approval process is expectede to be much simpler.
Strained economy makes genetically modified corn more palatable
Darkfrog submitted, created time 7 months 1 week (www.nytimes.com)
I've been saying it: Things affect each other in ways that we can't always predict. The global economy coupled with new interest in biofuels has made food prices skyrocket. The result? Soft drink companies in Asia are foregoing traditionally grown corn in favor of genetically modified corn.
Less pesticide, less herbicide, less expensive. Genetically modified corn deserves its shot!
Targeted gene knockout in mammalian cells by using engineered zinc-finger nucleases
davidd submitted, created time 7 months 1 week (www.pnas.org)
Gene knockout is the most powerful tool for determining gene function or permanently modifying the phenotypic characteristics of a cell. Existing methods for gene disruption are limited by their efficiency, time to completion, and/or the potential for confounding off-target effects. Here, they demonstrate a rapid single-step approach to targeted gene knockout in mammalian cells, using engineered zinc-finger nucleases (ZFNs).
Glowing Pig Passes Genes to Piglets
DanyC submitted, created time 10 months 3 weeks (news.nationalgeographic.com)
A cloned pig whose genes were altered to make it glow fluorescent green has passed on the trait to its young, a development that could lead to the future breeding of pigs for human transplant organs, a Chinese university reported.
Besides,Tokyo's Meiji University last year successfully cloned a transgenic pig that carries the genes for human diabetes, while South Korean scientists cloned cats that glow red when exposed to ultraviolet rays—an achievement they said could help develop cures for human genetic diseases
Researchers Prove How Plants Transport Sugars
Eric wu submitted, created time 10 months 4 weeks (www.sciencedaily.com)
How do many plants ship sugars from their leaves to flowers, roots, fruits and other parts of their structure? Using genetic engineering techniques, Cornell researchers have finally proven a long-standing theory of how this occurs.
Study finds first-ever genetic animal model of autism

By introducing a gene mutation in mice, investigators have created what they believe to be the first accurate model of autism not associated with a broader neuropsychiatric syndrome, according to research presented at the American College of Neuropsychopharmacology annual meeting.
