In recent medical/biotechnological breakthroughs: players in an online game simulating protein folding have successfully determined the 3-dimensional structure of a protein in a simian virus related to HIV, a hard problem which is not feasible to do with brute-force computation:

Teams of players collaborate to tweak a molecule’s model by folding it up in different ways. The result looks somewhat tangled, but each one is scored on criteria such as how tightly folded it is and whether the fold avoids atoms clashing. The structure with the highest score wins. Anyone can play and most of the gamers have little or no background in biochemistry.
“People have spatial reasoning skills, something computers are not yet good at. Games provide a framework for bringing together the strengths of computers and humans. The results in this week’s paper show that gaming, science and computation can be combined to make advances that were not possible before.”
Meanwhile, an experiment in using genetically modified HIV to destroy cancer cells has worked spectacularly well, with an experimental patient apparently having been cured of leukaemia, and remaining in full remission one year later:
At first, nothing happened. But after 10 days, hell broke loose in his hospital room. He began shaking with chills. His temperature shot up. His blood pressure shot down. He became so ill that doctors moved him into intensive care and warned that he might die. His family gathered at the hospital, fearing the worst. A few weeks later, the fevers were gone. And so was the leukemia.
But scientists say the treatment that helped Mr. Ludwig ... may signify a turning point in the long struggle to develop effective gene therapies against cancer. And not just for leukemia patients: other cancers may also be vulnerable to this novel approach — which employs a disabled form of H.I.V.-1, the virus that causes AIDS, to carry cancer-fighting genes into the patients’ T-cells. In essence, the team is using gene therapy to accomplish something that researchers have hoped to do for decades: train a person’s own immune system to kill cancer cells.
Meanwhile, HIV research has yielded an unexpected boon, in the form of cats that glow in the dark.

Researchers in South Carolina are getting closer to developing practical vat-grown meat, with no animals involved in its production:

If wine is produced in winery, beer in a brewery and bread in a bakery, where are you going to grow cultured meat? In a "carnery," if Mironov has his way. That is the name he has given future production facilities.
Dr. Mironov has taken myoblasts -- embryonic cells that develop into muscle tissue -- from turkey and bathed them in a nutrient bath of bovine serum on a scaffold made of chitosan (a common polymer found in nature) to grow animal skeletal muscle tissue. But how do you get that juicy, meaty quality? Genovese said scientists want to add fat. And adding a vascular system so that interior cells can receive oxygen will enable the growth of steak, say, instead of just thin strips of muscle tissue.
The researchers believe that cultured meat will eventually become cheaper than meat grown the traditional way, and also will allow for a greater variety of gastronomic possibilities.

Researchers at CMU write a program that learns facts by reading the web; hilarity ensues:

NELL also judges the facts it finds, promoting some of them to the higher category of “beliefs” if they come from a single trusted source, or if they come from multiple sources that are less reliable. According to the researchers, “More than half of the beliefs were promoted based on evidence from multiple [i.e., less reliable] sources,” making NELL more of a rumor mill than a trusted source. And once NELL promotes a fact to a belief, it stays a belief: “In our current implementation, once a candidate fact is promoted as a belief, it is never demoted,” a process that sounds more like religion than science.
Sometimes NELL makes mistakes: the computer incorrectly labeled “right posterior” as a body part. NELL proved smart enough to call ketchup a condiment, not a vegetable, a mislabeling that we owe to the “great communicator,” Ronald Regan. But its human handlers had to tell NELL that Klingon is not an ethnic group, despite the fact that many earthlings think it is. Alex Trebek would be happy to know that, unlike Sean Connery, NELL has no trouble classifying therapists as a “profession,” but the computer trips up on the rapists, which it thinks could possibly be “awardtrophytournament” (confidence level, 50%).
Told by its programmers that Risk is a board game, NELL predicts with 91.4% confidence that security risk is also a board game. NELL knows that a number is a character, but then incorrectly classifies the plural, numbers, as a character trait (93.8% confidence). The computer is also 99.9% confident that business is an academic field, which may be reassuring to those in the b-school if not to those small business owners worrying about the continuation of the Bush tax cuts.

A study of remains and literature from ancient Greece and Egypt suggests that cancer is a modern, man-made disease, one which was extremely rare in the ancient world. Which suggests that the fact that people these days can expect to get cancer if they live long enough is not due to an inherent cancer-proneness in human biology but rather due to other factors such as pervasive environmental carcinogens.

Finding only one case of the disease in the investigation of hundreds of Egyptian mummies, with few references to cancer in literary evidence, proves that cancer was extremely rare in antiquity. The disease rate has risen massively since the Industrial Revolution, in particular childhood cancer – proving that the rise is not simply due to people living longer.
Professor Rosalie David, at the Faculty of Life Sciences, said: “In industrialised societies, cancer is second only to cardiovascular disease as a cause of death. But in ancient times, it was extremely rare. There is nothing in the natural environment that can cause cancer. So it has to be a man-made disease, down to pollution and changes to our diet and lifestyle.”

A new technique involving ultraviolet light is revealing how ancient Greek statues were painted, by detecting traces of the organic compounds paints were made of. It turns out that the statues were coloured quite gaudily (indeed, some would say tackily), looking more like something you might find on a seaside pier than in a stately home.

And the fashion of subsequent millennia for alabaster-white statues of beautiful youths, female nudes, fauns and the like? Well, that's all based on the incorrect assumption that the way Classical Greek statues look now was the way they looked when they were made. (Indeed, I have heard the argument that the tendency towards minimalism in Western culture—as evidenced in High Modernism, for example—ultimately stems from the æsthetic values inculcated into the Western mindset through millennia of misinterpretation of Classical Greek artefacts.)

The Rap Guide To Human Nature is a hip-hop album about evolutionary psychology by a Canadian "rap troubador" named Baba Brinkman. It's not a joke: the beats are sharp, and Brinkman rhymes with the speed and dexterity of an accomplished rapper, deftly laying out the theories and controversies of evolutionary psychology, from kin selection to the biological roots of religious and political belief, twin studies to alternative models of human nature, and of course to areas such as sexual competition and social status where hip-hop culture and evolutionary psychology intersect. Note that, as expected from rap, the lyrics are probably not suitable for children.

Craig Venter (of Human Genome Project fame) has succeeded in creating synthetic life; i.e., of creating a living cell whose genome was entirely written from scratch in the laboratory. Venter's first commercialisation of the discovery will be a deal with ExxonMobil to create algae which absorb carbon dioxide and create hydrocarbon fuel. Beyond that, the possibilities are vast; from the mundane (cancer cures, new terrorist bioweapons, weird new designer drugs for mutant freak subcultures out of a Warren Ellis or John Shirley story) on to the horizon of the unimaginable.

And Quinn Norton says that we've just lost the War On Drugs, but not as badly as the drug lords, whose business model looks as doomed as the RIAA's:

You know what’s a lot easier than all the high minded business about environment, or life extension, or even the scary doomsday 12 Monkeys scenarios? Growing simpler molecule drugs. I don’t mean like aspirin, I mean like heroin and cocaine, THC and hallucinogens. They already grow in plants thoroughly studied, and people are motivated and not at all risk averse about getting those sequences somewhere they can use them. Cooking meth is hard and dangerous science compared to the ability to get a starter of a minimal cell that poops heroin and feeding it growth medium in your closet. We may have lost the drug war, but not as badly as the drug lords have.
It’s still hard to grow drugs in medium. But the whole point of this project is to make it easier. Who will be motivated to put in the work to make it happen? Especially if it’s so bad for organized crime? Drug addicts, frankly. You think they look like street junkies with DTs, but a fair number look like scientists, because they are. Drugs will finally be p2p, and governments and drug lords alike will find out what it’s like to be media companies and counterfeiters in a world of lossless copying and 100Mb pipes. Junkies will be victims of their success, and if we don’t get serious about treating addiction instead of trying to fight chemicals, it’s going to look a lot more bloody and horrid than the RIAA’s lawsuit factory. This is just one vision of what this kind of disruption looks like when people get a hold of it.

Frustrated by continued demands from viewers for more "awesome" and "extreme" programming, the president of the Science Channel (a US cable-TV channel) has taken a stand, refusing to dumb down his network's content any further:

"We already have a show called Really Big Things, which is just ridiculous if you think about it, and one called Heavy Metal Taskforce, which I guess deals with science on some distant level, though I don't know what it is. Plus, there's Punkin Chunkin. Punkin Chunkin, for Christ's sake," added Bunting, referring to the popular program in which contestants launch oversized pumpkins into the air using catapults. "What more do you people want?"
As evidence of their refusal to further water down programming, network sources pointed to a number of proposed shows they've abandoned in recent weeks, including an animal-based bungee-jumping program called Extreme Gravity, and Atom Smashers, a series that was was roundly rejected by focus groups as being "too technical" and "not awesome enough."
"People liked that the particle accelerators were really huge, but apparently the show didn't have enough smashing to hold their interest," said a former employee who wished to remain anonymous. "In the end, it was either add a huge monster truck for no reason whatsoever or pull the plug on the entire project. Honestly, I don't think I'd be able to face my wife and children had we gone through with it."

Scientists in the Netherlands have come one step closer to creating vat-grown meat. The team at Eindhoven University have grown muscle tissue from cells extracted from a pig. They still need to find a way of exercising the tissue to turn it into something resembling meat; at present, it is described as "a soggy form of pork", though they say that this development could lead to sausages in as little as five years.

It is hoped that, when it arrives, vat-grown meat will be vastly more environmentally efficient, requiring fewer resources to grow, not to mention being free of animal suffering. The current process is not vegetarian, though, using animal blood products in the growth medium.

On a tangent: earlier this year, scientists mapped the cow genome, and discovered that the genes involved in making cattle docile are in regions which, in humans, are involved in mental retardation.

A New York Times article from 10 years ago reveals that, over 40 years, Soviet scientists managed to create a domesticated variety of silver fox through selective breeding:

In a long-term experiment at a Siberian fur farm, geneticists have created this new version of Vulpes vulpes, the silver fox, by allowing only the friendliest animals from each generation to breed. Having selected only the most ''tamable'' of some 45,000 foxes over 35 generations, the scientists have compressed into a mere 40 years an evolutionary process that took thousands of years to transform ancestral wolves into domestic dogs.
The original purpose of the breeding was to create a friendly breed less likely than wild animals to fight when put to death. But in time, geneticists saw that far-reaching changes they observed in the foxes' physical and neurological makeup merited scientific study. The scientists apparently underwent some changes, too. Close bonds developed between the tame foxes and their human wardens, and the staff at the fur farm is trying to find ways of saving the animals from slaughter.
("Friendly" there seems like a euphemism; "gullible" or "stupid" might be more appropriate.)

The results of the experiment were domestic foxes ''as devoted as dogs but as independent as cats, capable of forming deep-rooted pair bonds with human beings'', which also developed a variety of physical differences from their wild ancestors:

The normal pattern of coat color that evolved in wild foxes as camouflage changed markedly in the genetically tamed fox population, with irregular piebald splotches of white fur appearing in some animals. The tame foxes sometimes developed floppy ears in place of the straight ones of wild foxes. The domesticated foxes generally had shorter legs and tails than ordinary foxes, and often had curly tails instead of straight, horizontal tails.
Moreover, the faces of adult tame foxes came to look more juvenile than the faces of wild adults, and many of the experimental animals developed dog-like features, Dr. Trut reported. Although no selective pressures relating to size or shape were used in breeding the animals, the skulls of tamable foxes tended to be narrower with shorter snouts than those of wild foxes.
Even more interesting were neurochemical differences: the tame foxes' adrenal glands, which produce adrenaline to prepare animals for fight or flight, had declined in hormone-producing ability with each generation, while after only 12 generations, their brains contained significantly higher levels of serotonin.

Unfortunately, it appears that the project ran out of money some time in the late 1990s, and most of the foxes were destroyed or sold off to fur breeders in Scandinavia. The institute had plans to sell pups as house pets, though it is not clear whether anything came of those.

A study in Japan, correlating suicide rates with lithium levels in water supplies, has found that lithium in the water supply reduces the suicide rate:

High doses of lithium are already used to treat serious mood disorders. But the team from the universities of Oita and Hiroshima found that even relatively low levels appeared to have a positive impact of suicide rates.
Levels ranged from 0.7 to 59 micrograms per litre. The researchers speculated that while these levels were low, there may be a cumulative protective effect on the brain from years of drinking this tap water.
The researchers hace stopped short of recommending that lithium be added to the water supply, in the way that fluoride is.

Recently, the media (and not only the tabloids, but the Guardian, the BBC and Reuters, to name a few) was full of headlines suggesting that consuming even small amounts of alcohol would significantly increase one's risk of cancer. Now, Charlie Stross tears that report apart, revealing that the paper in question actually said the opposite, even if its abstract, for some unfathomable reason, didn't:

... there was no dose response between the number of drinks the women consumed and their risk for all cancers. Women drinking no alcohol at all had higher incidences for all cancers than 95% of the drinking women.
The actual incidents of all cancers was 5.7% among the nondrinkers. The cancer incidents were lower among the women drinking up to 15 drinks a week: 5.2% among those consuming ≤2 drinks/week; 5.2% of those drinking 3-6 drinks/week; and 5.3% among those drinking 7-14 drinks a week. [Table 1.]
Of course, this leads to the question arises of why the abstract of the report contradicted its actual content, instead presenting a message at odds with it. Charlie suggests that it's not a mistake, but rather the result of Bush-era ideology, in which science receiving federal funding had to echo the official ideological line:
"Alcohol is evil. We know this because it is True. And it's especially bad for women because, well, women shouldn't drink. If you run a study to confirm this belief and the facts don't back you up, the facts are wrong. So tell the public the Truth (alcohol is always evil) and bury the facts; the press won't be able to tell the difference because they're (a) lazy (or overworked, take your pick) and (b) statistically innumerate."
This is pernicious fallout from the way the 2000-2008 Bush administration did business. Their contempt for science was so manifest that distortion and suppression of results that undermined a desired political objective became a routine reflex. If the science doesn't back you up, lie about it or suppress it. That administration may have been shown the door (and replaced by one that so far seems to have a pragmatic respect for facts), but the disease has spread internationally, becoming endemic wherever ideologically motivated politicians who hold their electorate in contempt find themselves seeking a stick to beat the public with.

The Amiga was the future in the 1980s, and let it not be said that the Amiga community is not still at the forefront of innovation.

A group calling itself Sense About Science, and dedicated to combatting scientific illiteracy, has published its review of scientifically illiterate statements made by celebrities in 2008. There were the usual one might expect (Tom Cruise's views on psychiatry, various others' advocacy of dubious "detox diets" and similar quackery), along with some real humdingers:

Sarah Palin, Mr McCain's running mate, waded into the mire with her dismissal of some government research projects. "Sometimes these dollars go to projects that have little or nothing to do with the public good. Things like fruit fly research in Paris, France. I kid you not," Ms Palin said. But the geneticist Ellen Solomon takes Ms Palin to task for not understanding the importance of studies into fruit flies, which share roughly half their genes with humans. "They have been used for more than a century to understand how genes work, which has implications in, for example, understanding the ageing process," she said.
Mind you, even the stupendously awesome Barack Obama (who, it must be said, has been recruiting sound scientific thinkers to his cabinet) is taken to task for suggesting that there may be a link between MMR vaccines and autism, which, according to Ben Goldacre, has been thoroughly discredited.

Today's new concept: lipodiesel:

A Beverly Hills plastic surgeon who claims to have turned fat, extricated in liposuction, into biofuel for his car has skipped town after US officials raided his surgery in an investigation into his procedures.
He reportedly wrote about the practice on his website, lipodiesel.com, which has since been shut down. "The vast majority of my patients request that I use their fat for fuel - and I have more fat than I can use,” he wrote.
The whole "lipodiesel" thing, though, could be a hoax, as some of the details don't match up. In addition, the surgeon in question is facing lawsuits for allegedly allowing unqualified assistants to operate on patients, and is apparently volunteering in a rural clinic in Colombia.

A study at Edinburgh's Heriot Watt University has claimed that watching romantic comedies can damage relationships, by inculcating unrealistic expectations:

They found fans of films such as Runaway Bride and Notting Hill often fail to communicate with their partner. Many held the view if someone is meant to be with you, then they should know what you want without you telling them.
Kimberly Johnson, who also worked on the study, said: "Films do capture the excitement of new relationships but they also wrongly suggest that trust and committed love exist from the moment people meet, whereas these are qualities that normally take years to develop."

New advances in neural imaging are shedding light on what makes a psychopath a psychopath:

In a landmark 1991 E.R.P. study conducted at a prison in Vancouver, Robert Hare and two graduate students showed that psychopaths process words like “hate” and “love” differently from the way normal people do. In another study, at the Bronx V.A. Medical Center, Hare, Joanne Intrator, and others found that psychopaths processed emotional words in a different part of the brain. Instead of showing activity in the limbic region, in the midbrain, which is the emotional-processing center, psychopaths showed activity only in the front of the brain, in the language center. Hare explained to me, “It was as if they could only understand emotions linguistically. They knew the words but not the music, as it were.”
Today, Kiehl and Hare have a complementary but complicated relationship. Kiehl claims Hare as a mentor, and sees his own work as validating Hare’s checklist, by advancing a neurological mechanism for psychopathy. Hare is less gung ho about using fMRI as a diagnostic tool. “Some claim, in a sense, this is the new phrenology,” Hare said, referring to the discredited nineteenth-century practice of reading the bumps on people’s heads, “only this time the bumps are on the inside.”
But the problem is that “psychopathic behavior”—egocentricity, for example, or lack of realistic long-term goals—is present in far more than one per cent of the adult male population. This blurriness in the psychopathic profile can make it possible to see psychopaths everywhere or nowhere. In the mid-fifties, Robert Lindner, the author of “Rebel Without a Cause: A Hypnoanalysis of a Criminal Psychopath,” explained juvenile delinquency as an outbreak of mass psychopathy. Norman Mailer inverted this notion in “The White Negro,” admiring the hipster as a “philosophical psychopath” for having the courage of nonconformity. In the sixties, sociopathy replaced psychopathy as the dominant construct. Now, in our age of genetic determinism, society is once again seeing psychopaths everywhere, and this will no doubt provoke others to say they are nowhere, and the cycle of overexposure and underfunding will continue.
One researcher is doing research on prison inmates (a population in which psychopathy is greatly over-represented, as one might expect) using a brain scanner and tests reminiscent of the Voigt-Kampf test in Blade Runner, measuring their responses to moral questions non-psychopathic individuals would respond to viscerally.
The fMRI machine started up with a high-pitched whirring sound. I began to see photographs. One was of a baby covered with blood. I thought first about the blood, then realized the circumstances—birth—and rated the moral offense zero. A man was lying on the ground with his face beaten to a bloody pulp: I scored this high. There was a picture of Osama bin Laden. I scored it four, although I felt that I was making more of an intellectual than a moral judgment. Two guys inadvertently butting heads in a soccer game got a zero, but then I changed it to a one, because perhaps a foul was called. I had considered deliberately giving wrong answers, as a psychopath might. But instead I worked at my task earnestly, like a good fifth grader.

A biologist and a sociologist have put forward a new theory of brain development and mental disorders. Crespi and Badcock's theory posits a spectrum running between autism and related social dysfunctions on one side and schizophrenia, depression and bipolar disorder on the other, with the struggle between maternal and paternal genes in the womb determining where the child's neurology will fall on this axis:

Dr. Crespi and Dr. Badcock propose that an evolutionary tug of war between genes from the father’s sperm and the mother’s egg can, in effect, tip brain development in one of two ways. A strong bias toward the father pushes a developing brain along the autistic spectrum, toward a fascination with objects, patterns, mechanical systems, at the expense of social development. A bias toward the mother moves the growing brain along what the researchers call the psychotic spectrum, toward hypersensitivity to mood, their own and others’. This, according to the theory, increases a child’s risk of developing schizophrenia later on, as well as mood problems like bipolar disorder and depression.
It was Dr. Badcock who noticed that some problems associated with autism, like a failure to meet another’s gaze, are direct contrasts to those found in people with schizophrenia, who often believe they are being watched. Where children with autism appear blind to others’ thinking and intentions, people with schizophrenia see intention and meaning everywhere, in their delusions. The idea expands on the “extreme male brain” theory of autism proposed by Dr. Simon Baron-Cohen of Cambridge.
“Think of the grandiosity in schizophrenia, how some people think that they are Jesus, or Napoleon, or omnipotent,” Dr. Crespi said, “and then contrast this with the underdeveloped sense of self in autism. Autistic kids often talk about themselves in the third person.”

The US election season is proving a bonanza to scientists studying deception, from incongruous body language to the vague phraseology of "spin":

BLINK and you would have missed it. The expression of disgust on former US president Bill Clinton's face during his speech to the Democratic National Convention as he says "Obama" lasts for just a fraction of a second. But to Paul Ekman it was glaringly obvious.
"Given that he probably feels jilted that his wife Hillary didn't get the nomination, I would have to say that the entire speech was actually given very gracefully," says Ekman, who has studied people's facial expressions and how they relate to what they are thinking for over 40 years.
Another algorithm scores politicians on the amount of spin, or manipulative content-free language, in their speeches, using word frequencies:
The algorithm counts usage of first person nouns - "I" tends to indicate less spin than "we", for example. It also searches out phrases that offer qualifications or clarifications of more general statements, since speeches that contain few such amendments tend to be high on spin. Finally, increased rates of action verbs such as "go" and "going", and negatively charged words, such as "hate" and "enemy", also indicate greater levels of spin. Skillicorn had his software tackle a database of 150 speeches from politicians involved in the 2008 US election race (see diagram).
In general though, Obama's speeches contain considerably higher spin than either McCain or Clinton. For example, for their speeches accepting their party's nomination for president, Obama's speech scored a spin value of 6.7 - where 0 is the average level of spin within all the political speeches analysed, and positive values represent higher spin. In contrast, McCain's speech scored -7.58, while Hillary Clinton's speech at the Democratic National Convention scored 0.15. Skillicorn also found that Sarah Palin's speeches contain slightly more spin than average.
So whilst Obama is one slick player, the straight-talkin', plain-dealin' McCain has little to rejoice about, according to a different metric:
"The voice analysis profile for McCain looks very much like someone who is clinically depressed," says Pollermann, a psychologist who uses voice analysis software in her work with patients. Previous research on mirror neurons has shown that listening to depressed voices can make others feel depressed themselves, she says.
Additionally, McCain's voice and facial movements often do not match up, says Pollermann, and he often smiles in a manner that commonly conveys sarcasm when addressing controversial statements. "That might lead to what I would call a lack of credibility."

The secretive totalitarian state of North Korea, the last place on Earth ruled by a God-Emperor, has made a technological breakthrough, developing a noodle which delays feelings of hunger:

"When you consume ordinary noodles (made from wheat or corn), you may soon feel your stomach empty. But this soybean noodle delays such a feeling of hunger," it said on its website.
This is not North Korea's first invention in the field of nutritional technology (some five years earlier, they invented the computer drink), though does suggest a heightened desperation to feed a starving people (or at least a hungry soldiery required to keep those people from rising up). Though presumably once that's taken care of, the North Koreans can look forward to export income from Westerners concerned about their weight.

Muslim scientists have called for Mecca time to replace Greenwich Mean Time as the international standard. Other than the religious argument (not likely to sway many non-Muslims) and the postcolonial argument, they contend that unlike other longitudes, Mecca's was "in perfect alignment to magnetic north":

He said the English had imposed GMT on the rest of the world by force when Britain was a big colonial power, and it was about time that changed.
A prominent cleric, Sheikh Youssef al-Qaradawy, said modern science had at last provided evidence that Mecca was the true centre of the Earth; proof, he said, of the greatness of the Muslim "qibla" - the Arabic word for the direction Muslims turn to when they pray.
(Youssef al-Qadarawy? Where have I heard that name before?)
The meeting in Qatar is part of a popular trend in some Muslim societies of seeking to find Koranic precedents for modern science.
