The scientists extracted cells from the muscle of a live pig and then put them in a broth of other animal products. The cells then multiplied and created muscle tissue. They believe that it can be turned into something like steak if they can find a way to artificially "exercise" the muscle.

Meat and dairy consumption is predicted to double by 2050 and methane from livestock is said to currently produce about 18 per cent of the world’s greenhouse gases.

Clever fools: Why a high IQ doesn't mean you're smart - life - 02 November 2009 - New Scientist

"A high IQ is like height in a basketball player," says David Perkins, who studies thinking and reasoning skills at Harvard Graduate School of Education in Cambridge, Massachusetts. "It is very important, all other things being equal. But all other things aren't equal. There's a lot more to being a good basketball player than being tall, and there's a lot more to being a good thinker than having a high IQ."

The Atlantic Online | November 2009 | Does the Vaccine Matter? | Shannon Brownlee and Jeanne Lenzer

Jackson’s findings showed that outside of flu season, the baseline risk of death among people who did not get vaccinated was approximately 60 percent higher than among those who did, lending support to the hypothesis that on average, healthy people chose to get the vaccine, while the “frail elderly” didn’t or couldn’t. In fact, the healthy-user effect explained the entire benefit that other researchers were attributing to flu vaccine, suggesting that the vaccine itself might not reduce mortality at all.

Dunning–Kruger effect - Wikipedia, the free encyclopedia
en.wikipedia.org/wiki/Dunning-Kruger_effect, posted 2009 by peter in business health management people
The Dunning–Kruger effect is an example of cognitive bias in which "...people reach erroneous conclusions and make unfortunate choices but their incompetence robs them of the metacognitive ability to realize it".[1] They therefore suffer an illusory superiority, rating their own ability as above average. This leads to a perverse result where people with less competence will rate their ability more highly than people with relatively more competence. It also explains why competence may weaken the projection of confidence because competent individuals falsely assume others are of equivalent understanding. "Thus, the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others."[1]

Artistic tendencies linked to 'schizophrenia gene' - health - 16 July 2009 - New Scientist
www.newscientist.com/article/dn17474-artistic-tendencies-linked-to-schizophrenia-gene.html, posted 2009 by peter in art health science toread
We're all familiar with the stereotype of the tortured artist. Salvador Dali's various disorders and Sylvia Plath's depression spring to mind. Now new research seems to show why: a genetic mutation linked to psychosis and schizophrenia also influences creativity.
The finding could help to explain why mutations that increase a person's risk of developing mental illnesses such as schizophrenia and bipolar syndrome have been preserved, even preferred, during human evolution, says Szabolcs Kéri, a researcher at Semmelweis University in Budapest, Hungary, who carried out the study.

BBC NEWS | Health | 'Brain decline' begins at age 27
news.bbc.co.uk/1/hi/health/7945569.stm, posted 2009 by peter in health msm science
The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability.
Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.
