You could try, but probably wouldn't want to be around when you released it. The prospect that rogue scientists could develop bioweapons designed to target certain ethnic groups based on their genetic differences was raised this week in a report by the British Medical Association (BMA).
It's not easy getting old. The body starts to break down, and the mind begins to fade. These things, it is often thought, will leave us depressed and unhappy. As researchers are finding out, however, they actually don't.
These ravages of time, as it turns out, have very little to do with one's happiness. Actually, older people report being just as happy, if not happier, than their younger compatriots. Researchers who study aging and happiness have dubbed this the "paradox of well-being."
But why? What's going on?
Has anyone on the Examiner or Kirklees Council considered the possibility that there could be a connection between the 2008/9 resurgence of the "push" for fluoridation, the article in the Examiner, December 16 featuring Dr Peter Clemenson of Huddersfield University and the brief UK Press announcement stating that Britain has sold off its stake in the Aldermaston Weapons Establishment, relinquishing control of nuclear war head production in the UK?
Do any of the Kirklees councillors realise that the fluoride tank washings from several major industries including the nuclear industry and the hazards of their disposal could be at the root of the Government's persistence in attempting to delude populations throughout the country into accepting the totally false propaganda, that fluoride is essential to the prevention of tooth decay.

And yet, city life isn't easy. The same London cafes that stimulated Ben Franklin also helped spread cholera; Picasso eventually bought an estate in quiet Provence. While the modern city might be a haven for playwrights, poets, and physicists, it's also a deeply unnatural and overwhelming place.
Research led by Iowa State University scientists has them a step closer to finding a way to counter the Ebola virus.
A team led by Gaya Amarasinghe, an assistant professor in biochemistry, biophysics and molecular biology, has recently solved the structure from a key part of the Ebola protein known as VP35.
VP35 interferes with the natural resistance of host cells against viral infections.
"Usually when viruses infect cells, the host immune system can fight to eventually clear the virus. But with Ebola infections, the ability of the host to mount a defense against the invading virus is lost," said Amarasinghe.

Little was known about people's exposure to such compounds from drinking water, so Shane Snyder and colleagues at the Southern Nevada Water Authority in Las Vegas screened tap water from 19 US water utilities for 51 different compounds. The surveys were carried out between 2006 and 2007.
The 11 most frequently detected compounds - all found at extremely low concentrations - were:
- Atenolol, a beta-blocker used to treat cardiovascular disease
- Atrazine, an organic herbicide banned in the European Union, but still used in the US, which has been implicated in the decline of fish stocks and in changes in animal behaviour
- Carbamazepine, a mood-stabilising drug used to treat bipolar disorder, amongst other things
- Estrone, an oestrogen hormone secreted by the ovaries and blamed for causing gender-bending changes in fish
Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. The findings may help explain why people with sleep apnea are more likely to suffer strokes and to die in their sleep.
Sleep apnea is the most commonly diagnosed condition amongst sleep-related breathing disorders and can lead to debilitating and sometimes fatal consequences for the 18 million Americans who have been diagnosed with the disorder. This study identifies a mechanism behind stroke in these patients.
The study, "Impaired cerebral autoregulation in obstructive sleep apnea" was carried out by Fred Urbano, Francoise Roux, Joseph Schindler and Vahid Mohsenin, all of the Yale University School of Medicine in New Haven, Connecticut. It appears in the current issue of the Journal of Applied Physiology.

Fluoride will be pumped into southeast Queensland's water supplies around-the-clock from today as the State Government steps up its oral health campaign.
Premier Anna Bligh said water treatment plants would produce an ongoing supply after fluoride powder was sporadically introduced in the past few weeks. Almost 80 per cent of southeast households will have fluoride, with only Toowoomba, Caboolture, Redlands and pockets of the Sunshine Coast north of the Maroochy River to come.

Playing on computer consoles activates parts of the male brain which are linked to rewarding feelings and addiction, scans have shown. The more opponents they vanquish and points they score, the more stimulated this region becomes.
In contrast, these parts of women's brains are much less likely to be triggered by sessions on the Sony PlayStation, Nintendo Wii or Xbox.
Professor Allan Reiss of the Centre for Interdisciplinary Brain Sciences Research at Stanford University, California, who led the research, said that women understood computer games just as well as men but did not have the same neurological drive to win.
Using new technologies that make it easier to sequence the human genome, researchers at the University of Michigan Comprehensive Cancer Center have identified a series of genes that become fused when their chromosomes trade places with each other. These recurrent gene fusions are thought to be the driving mechanism that causes certain cancers to develop.
The gene fusions discovered could potentially serve as a marker one day for diagnosing cancer or as a target for future drug development.
In the new study, published in Nature, the researchers identified several gene fusions in prostate cancer cells. Some of the fusions were seen in multiple cell lines studied, while other gene fusions appeared only once. The fusions were found only in cancer cells, and not in normal cells.
