Tjeerd writes "There is currently a discussion going on in the Netherlands about embryo selection. The process means that when using in vitro fertilization, you can check what kind of genetic defects will definitely become activated during life. When embryos with those defects are identified, they can be avoided or destroyed. The next step the government is considering is to make it possible to select against genetic defects which might become active in life, such as breast and colon cancer. Of course, this is a very difficult discussion; where do you start, and where do you end? People are worrying that there is no real limit, and that you could potentially check for every genetic defect. I think if you're in a situation where you or your family have genetic defects, you surely want to check whether your children would have them too. What does the Slashdot community think about this?"

Bored MPA writes "The Times reports that PETA is to announce plans on Monday for a $1 million prize to the "first person to come up with a method to produce commercially viable quantities of in vitro meat at competitive prices by 2012." PETA founder Ingrid Newkirk addressed the controversial decision by saying, "We don't mind taking uncomfortable positions if it means that fewer animals suffer." An unexpected and pragmatic move from an organization that has a strong base of support from pro-organic vegans." The question I always had about this- if they can take one sample from one animal and clone it in a vat and feed this world, will the vegans be ok with that?

statemachine writes to mention that the USDA and farmers took part in a 5-year study of switchgrass, a grass native to North America. The study found that switchgrass ethanol can deliver around 540 percent of the energy used to produce it, as opposed to corn ethanol which can only yield around 24 percent. "But even a native prairie grass needs a helping hand from scientists and farmers to deliver the yields necessary to help ethanol become a viable alternative to petroleum-derived gasoline, Vogel argues. 'To really maximize their yield potential, you need to provide nitrogen fertilization,' he says, as well as improved breeding techniques and genetic strains. 'Low input systems are just not going to be able to get the energy per acre needed to provide feed, fuel and fiber.'"

wattrlz writes "In a development reminiscent of nineteenth century pseudo-science, the father-son team of Kong Thon and Shaw Wei Tsen recently demonstrated that the tobacco mosaic virus can be destroyed in vitro by nano-scale mechanical resonant vibrations induced by repeated ultra-short pulses from a laser. The total energy required is reportedly far below the threshold for human tissue damage and the technique should generalize to human pathogens. Cleaning stored blood is one obvious application."

mikesd81 writes "The Washington Post has an article about a team of American and Irish researchers that have discovered that some female sharks can reproduce without having sex, the first time that scientists have found the unusual capacity in such an ancient vertebrate species. Their report concludes that sharks can reproduce asexually through the process known as parthenogenesis (the growth and development of an embryo or seed without fertilization by a male). Scientists started investigating after a female hammerhead shark was mysteriously born at Omaha's Henry Doorly Zoo in a tank that housed 3 female sharks. It was originally thought one had stored sperm from a male shark before fertilizing an egg. However, baby shark's genetic makeup perfectly matched one of the females in the tank, with no sign of a male parent."

daftna writes in with a story from Nature about a pair of twins who are neither identical nor fraternal: they are semi-identical. Researchers discovered twins who share all of their mother's DNA but only half of their father's. Both children are chimeras — their cells are not genetically uniform, but include a mix of genes from two separate sperm cells that fertilized a single egg. This is, apparently, not as rare as one might think; but the resulting fetus is rarely viable. This report marks the first known incidence of two half-identical twins resulting from a double fertilization.

Yale researchers claim to have found the very first neurons in what eventually becomes the human brain. Developed before most anything else, these neurons are in place just 31 days after fertilization. From the article: "We hypothesize that these predecessor neurons may be a transient population involved in determining the number of functional radial units including the human specific regions of the cerebral cortex mediating higher cognitive functions," Rakic said. "As a next step it is essential to determine their neural stem cell lineage, pattern of gene expression, developmental role and eventual fate."

gollum123 writes "The BBC reports that scientists from the UK and France have may found a gene responsible for controlling the fertilization of a new egg." From the article: "The HIRA gene is involved in the events necessary for the fertilisation that take place once a sperm enters an egg. Faults in this gene might explain why some couples struggle to get pregnant despite having healthy sperm ... Although their work in Nature is based on fruit flies, the same genetic processes are present in humans."

sbar writes "The 2004 Abel prize-winners have been announced.From the website: 'The Atiyah-Singer index theorem is one of the great landmarks of twentieth century mathematics, influencing profoundly many of the most important later developments in topology, differential geometry and quantum field theory. Its authors, both jointly and individually, have been instrumental in repairing a rift between the worlds of pure mathematics and theoretical particle physics, initiating a cross-fertilization which has been one of the most exciting developments of the last decades.'"

understyled writes "According to this article, researchers from Fukui Prefectural University in Obama, Japan, and the National Human Genome Research Institute have produced genetically modified zebrafish using sperm cells grown "in vitro." "The secret to our success was the idea of placing a layer of special 'feeder cells' under the spermatagonia in the laboratory dish. These feeder cells, derived from zebrafish testicular cancer cell lines, promote the growth of spermatagonia and stimulate them to mature into functional sperm," said Dr. Sakai, the study's senior author and a reproductive biologist."
