Monsanto Is Going Organic in a Quest for the Perfect Veggie
- "The lettuce, peppers, and broccoli—plus a melon and an onion, with a watermelon soon to follow—aren't genetically modified at all. Monsanto created all these veggies using good old-fashioned crossbreeding, the same technology that farmers have been using to optimize crops
for millennia. That doesn't mean they are low tech, exactly. Stark's division is drawing on Monsanto's accumulated scientific know-how to create vegetables that have all the advantages of genetically modified organisms without any of the Frankenfoods ick factor." [more inside]

Is Psychometric g a Myth?

Science Fiction Comes Alive as Researchers Grow Organs in Lab
1997 -- Charles Vacanti of University of Massachusetts Medical Center and Robert Langer of Massachusetts Institute of Technology report the growing of a cartilage structure – in the shape of a human ear – on a mouse’s back. 2008 -- Doris Taylor at the University of Minnesota and colleagues grow a beating rat heart in the lab. 2008 --Surgeons in Spain transplant a new windpipe into a patient. The organ is made from a cadaver windpipe stripped of its original cells and reseeded with the patient’s own cells. 2010 -- Researchers at Mass General Hospital grow a rat liver. 2010 -- Yale University scientists grow a functioning rat lung. 2010 -- Alex Seifalian in London transplants a lab-made tear duct into patient 2011 -- Dr. Seifalian makes a windpipe from nanocomposite materials plus a patient’s own stem cells; the new windpipe replaces the patient’s cancerous one, saving his life. In a separate procedure, an artery made at Dr. Seifalian’s lab is transplanted into a patient. 2012 -- Surgeons in Sweden transplant a major blood vessel into a 10-year-old girl. The vein was taken from a dead man, stripped of its tissue, then reseeded with the girl’s own cells. 2013 -- Scientists from Cornell University report the making of a human ear using living cartilage cells.

The Triumph of New-Age Medicine "Medicine has long decried acupuncture, homeopathy, and the like as dangerous nonsense that preys on the gullible. Again and again, carefully controlled studies have shown alternative medicine to work no better than a placebo. But now many doctors admit that alternative medicine often seems to do a better job of making patients well, and at a much lower cost, than mainstream care—and they’re trying to learn from it."

on the water some ways south of Iceland. The very next day lava and tephra broke the surface of the Atlantic and by May, 1964 the formation had grown to 2.4 km². Over the next three years lava eruptions continued, coating the loose debris in a hard shell and protecting it from erosion. An island born

The Human Speechome Project
- "A baby is to be monitored
by a network of microphones and video cameras for 14 hours a day, 365 days a year, in an effort to unravel the seemingly miraculous process by which children acquire language.". Selected video clips
(PDF, 750KB). To test hypotheses of how children learn, Prof Deb Roy's team at MIT will develop machine learning systems that “step into the shoes” of his son by processing the sights and sounds of three years of life at home. Total storage required: 1.4 petabytes

Thou shalt not make scientific progress.
"Medical research is poised to make a quantum leap that will benefit sufferers from Alzheimer's, Parkinson's, muscular dystrophy, diabetes and other diseases. But George W. Bush's religious convictions stand in its way."

Gene Prevents 'Brains Everywhere'
The human version of the gene probably is not involved in keeping the human brain inside the skull, but likely plays some other role in nervous system development in human embryos, says Alejandro Sanchez Alvarado, a developmental biologist at the University of Utah School of Medicine.

Thrown off the scent.
A fascinating story about The Pill and its effect on women's mate choice, and the effect of these choices on evolution. T-shirts belonging to unknown men were given to women to smell. All they had to do was say which smelt best. Women on the pill chose exactly the opposite t-shirts to those that didn't - find me free will, personal taste and the nature / culture divide in that if you can... [found via Plastic
