DNA test developed in Glasgow links ageing and poverty

by jeeg 12. August 2011 20:30
Scientists in Glasgow have developed a new test of the ageing process based on DNA evidence. They have said it could provide faster feedback on public health measures. Until now, evidence of health improvement has involved waiting a generation or more to measure how many people become ill. Work by the Glasgow Centre for Population Health has confirmed the link between social factors and the rate at which people age. Their findings have been published in the Public Library of Science. ... [More]

Arrested and Swabbed: DNA Tests Challenged

by jeeg 11. August 2011 23:33
Serial killer Dennis Rader was caught with the help of DNA analysis. Now, laws in 25 states allow for DNA samples even before a conviction. Cheek swabs or blood samples from those arrested for felonies offer law enforcement officials unique identifying tags, much like fingerprints or bar codes on products. These tags are recorded in state and national databases and can be used later to match samples from the scenes of crimes that haven't been solved. The practice of taking fingerprints o... [More]

Is Craig Venter going to save the planet? Or is this more hype from one of America’s most controversial scientists?

by jeeg 11. August 2011 23:20
In a pristine white greenhouse in La Jolla, Calif., maverick molecular biologist Craig Venter is showing off tubs of dark green goop that might help rescue the planet. Winter sunlight streams through the glass roof onto rows of long, white troughs filled with algae and seawater. A little water wheel in each trough turns to keep the liquid circulating and the growing cells evenly exposed to light and to carbon dioxide-enriched air. Computers maintain a constant temperature. Giant transpare... [More]

Is Public Health and Safety Being Considered in the Construction of LBNL's New Biolab in Berkeley?

by jeeg 11. August 2011 20:26
In April of this year, U.C. Berkeley researchers announced the creation of the U. C. Berkeley Synthetic Biology Institute (SBI), which will ramp up efforts to “engineer” cells and biological systems. Part of its research will include experiments that insert manufactured stretches of DNA into existing organisms to create new, self-replicating artificial life forms—experiments that pose implications for worker safety, public health and environmental safety. A collaboratio... [More]

Test Can Tell Fetal Sex at 7 Weeks, Study Says

by jeeg 10. August 2011 21:26
A simple blood test that can determine a baby’s sex as early as seven weeks into pregnancy is highly accurate if used correctly, a finding that experts say is likely to lead to more widespread use by parents concerned about gender-linked diseases, those who are merely curious and people considering the more ethically controversial step of selecting the sex of their children. The appeal of the test, which analyzes fetal DNA found in the mother’s blood, is that it can establish... [More]

Indian National Biodiversity Authority to take action against Bt Brinjal biopiracy

by jeeg 10. August 2011 20:04
The development of Bt Brinjal was a case of biopiracy, according to the National Biodiversity Authority (NBA). According to sources, the NBA has finally concluded its year-long investigation and recommended action against the U.S. agribusiness giant, Monsanto, and its Indian collaborators, who developed and promoted the controversial, genetically modified vegetable. A decision to “take the case to its logical conclusion” was taken in an NBA meeting on June 20, according to of... [More]

Are half the men in Europe related to King Tut?

by jeeg 9. August 2011 02:21
A Swiss genomics company says so, but scientists call claim a bunch of bunk A personal genomics company in Switzerland says they've reconstructed a DNA profile of King Tutankhamen by watching the Discovery Channel, claiming the results suggest more than half of Western European men are related to the boy king. But researchers who worked to decode Tut's genome in the first place say the claim is "unscientific." Swiss genomics company iGENEA has launched a Tutankhamen DNA project based... [More]

NHS ignores gene patents, experts say

by jeeg 8. August 2011 23:49
Genetic testing laboratories in the National Health Service are deliberately ignoring most patents on DNA, experts told a meeting in London on Friday. “The view from the NHS is that, for diagnostics, gene patents are unacceptable, unenforceable and detrimental to the delivery of patient services,” said Gail Norbury, commissioning and governance director of the Genetics Labs at Guy’s Hospital, who is one of Britain’s leading clinical geneticists. Although hundreds ... [More]

DNA: Law requiring arrestees' samples struck down

by jeeg 8. August 2011 23:31
A voter-approved California law requiring police to collect DNA samples from anyone arrested for a felony violates the constitutional privacy rights of people who have not been charged with or convicted of a crime, a state appeals court ruled Thursday. The law expanded previous statutes that authorized law enforcement officials to take DNA from convicts and suspects with felony records. Approved by 62 percent of the voters in 2004 and effective in 2009, it required anyone arrested on su... [More]

Genetically Modified Beagle Glows

A genetically modified female beagle named Tegon glows bright fluorescent green under ultraviolet light, according to a paper published in the journal Genesis. In the scientific record books, Tegon joins a red fluorescent puppy named Ruppy and Mr. Green Genes the cat as all being human-modified animals that can glow. ByeongChun Lee, a co-author of the Genesis paper, told Discovery News, "The entire body of the dog glows. One can witness a slightly yellower change in the color of the dog'... [More]
