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.
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.”
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.
Analysis of street cocaine found in Britain has shown that your typical sample is about 10% pure, with the rest being made up, essentially, of anything white and powdery, including some rather nasty chemicals:
Much of the seized cocaine is found to have been cut with phenacetin - a pharmaceutical drug banned some years ago in Britain and most other nations for causing kidney failure and cancer.
Other drugs used for cutting or "bashing" cocaine include lignocaine (a dental painkiller), tetramisole (used for de-worming pets) and boric acid (used to kill cockroaches).Not that such revelations are likely to dampen demand for what is essentially Britain's national drug. After all, the risk of an agonising death from cancer hasn't put many people off bacon, and cocaine feeds into the celebrity-obsessed, superficially success-oriented bling culture of Blatcherite Britain; and even if people know that the £2.50 line of coke they do is unlikely to be like anything their footballer/WAG/indie-star idols touch, suspension of disbelief is a powerful thing.
The problem, of course, is that cocaine is, by definition, sold by criminals, and there is no incentive for anything remotely like fair dealing. One answer, of course, would be to legalise cocaine and regulate it as stringently as alcohol and tobacco are. As soon as that happened, coke dealers would go the way of bathtub gin merchants and the quality and reliability would go up; Waitrose would carry organic, fair-trade cocaine from day one, and for those on a budget, £3.79 would get you a line of Tesco Value coke (3% purity, but cut with thoroughly innocuous substances). Lidl would undoubtedly come to the party with a janky-looking faux-authentic store brand; "Medellin Hills", perhaps, or "Mr. Montana's"?
Of course, legalising drugs is the sort of thing only somebody with an excess of common sense would advocate, and there is no way that it would ever happen in the real world. Thankfully, there are other, more politically viable, possibilities. Given that the majority of the active ingredient in street cocaine is not actually cocaine but various tranquillisers (hence the feeling of numbness which many naïve cokeheads assume as proof of the drug's authenticity), the next logical step would be to do away with the illegal substance altogether and sell perfectly legal pseudococaine. It'd have the right colour, texture and consistency for doing a social line at a party, would function excellently as a prop for one's fantasies of celebrity glamour, and would even give one a mild buzz, though would contain nothing more dangerous (or illegal) than a few stimulants and tranquillisers, heavily diluted.
According to the UK's Public Health minister, pregnant teenagers are deliberately taking up smoking to have smaller babies and thus an easier birth.
While the rest of the world is closing its doors to refugees, Belarus's neo-Soviet dictator Alexander Lukashenko, is allowing them to settle and get full asylum — with the proviso that they settle in radiation-contaminated areas near Chernobyl. They will even get fully-furnished houses (as abandoned by their original residents some 19 years ago), and will live a life of luxury, as long as they don't mind getting cancer.
"Lukashenko wants to draw a line under the Chernobyl catastrophe and allow the area to regain its economic value." The government is especially keen to get the agricultural sector back on its feet again. Berries and mushrooms, which absorb radiation especially well, flourish here.
It looks like Australia may be facing another tightening of its already notorious censorship laws, this time governing TV nudity; Australia's equivalent of the Janet Jackson nipple outrage is reality-TV-show contestants getting it on in a hot-tub, which has made it into Federal parliamentary debates:
"What we basically have is pornography and full frontal nudity on television at a time when children are watching. These people have an aspiration to be porn stars," Draper told Reuters.It's hard to believe that this is the country that, only five years earlier, was considering introducing a "non-violent erotica" film classification.
At least Howard/Hillsong Australia c.2005 isn't quite as bad as Iran, where the government is microwaving its own population to save them from satellite-TV-borne "westoxication". The huge volumes of microwaves being pumped into population centres as Iran's elections approach are claimed to cause everything from migraines to birth defects or worse; though what are a few brain tumours compared to eternal salvation?
A Roman Catholic cardinal and a priest in charge of Vatican Radio have been convicted of polluting the atmosphere with electromagnetic radiation; studies have found that magnetic fields around the Vatican Radio transmitters north of Rome were much higher than normal limits allow, and may have caused high rates of cancer in the area.
A study in the Netherlands has found that the air in churches is a health hazard. Due to poor ventilation and the use of candles and incense, church air has 12 to 20 times the European allowed average concentration of carcinogenic particles. The study also found various types of free radicals in the air, including previously undocumented ones.
It'd be interesting to see whether cancer rates among frequent churchgoers are above the average, and if not, whether that is attributable to much-vaunted psychosomatic effects of religious faith (or, for the red-staters out there, the Almighty's miraculous protection of His flock).
Intestinal worms may prevent bowel cancer; as such, a health drink containing whipworm eggs to replenish your body's supply of the
parasites symbionts may soon go on the market in Europe. The worms will be the pig variety, which doesn't survive long in humans, and is less likely to cause complications. (via FmH)
I wonder how long until we all have personalised populations of genetically engineered ex-parasites, modified to eliminate potential health problems long before any symptoms would arise, in our bowels, bloodstreams and elsewhere.
Tikka masala, Britain's national curry dish, has been found to contain carcinogenic dyes, often at illegal levels. The additives, tartrazine (E102), Ponceau 4R (E124) and the appropriately sinister-sounding Sunset Yellow (E110), add nothing to the flavour, but give the dish its distinctive yellow colour, without which many customers wouldn't eat it. (I wonder whether the tikka masala pastes/sauces you can buy in supermarkets are similarly carcinogenic.)
A claim has emerged from Ireland (where else?) that incense, of the sort used in Catholic churches, can cause cancer, with altar boys and girls being at particular risk from carcinogens in the smoke. Ireland, once the most fiercely Catholic state in Europe, is currently banning the smoking of tobacco in most public places.
Scientists at Johns Hopkins University have found that assessing a community's cancer risk could be as simple as counting the number of trucks and cars that pass through the neighborhood. Another reason to encourage the development of public transport. Not that anybody's listening here, with the government falling over itself to spend billions of dollars on new freeways and spending only the most grudging pittance on public transport (which is next to useless outside of the inner city). (thanks, Toby)
Covering all bases: One of the world's largest tobacco companies is poised to get exclusive rights to market future lung cancer vaccines, a move which could net it billions of dollars.
