Yes. We understand the potential benefits of the technology, and support continued advances in molecular biology, the underlying science. But we are critics of the business models and regulatory systems that have characterized early deployment of these technologies. GE has proved valuable in some areas (as in the contained use of engineered bacteria in pharmaceutical development), and some GE applications could turn out to play a useful role in food production.

Thus far, however, GE applications in agriculture have only made the problems of industrial monocropping worse. Rather than supporting a more sustainable agriculture and food system with broad societal benefits, the technology has been employed in ways that reinforce problematic industrial approaches to agriculture. Policy decisions about the use of GE have too often been driven by biotech industry public relations campaigns, rather than by what science tells us about the most cost-effective ways to produce abundant food and preserve the health of our farmland.

These are a few things policy makers should do to best serve the public interest:

Atlas shows how genes affect our metabolism

Posted: May 12, 2014 at 8:44 am

PUBLIC RELEASE DATE:

11-May-2014

Contact: Mark Thomson press.office@sanger.ac.uk 01-223-492-384 Wellcome Trust Sanger Institute

In the most comprehensive exploration of the association between genetic variation and human metabolism, researchers have provided unprecedented insights into how genetic variants influence complex disease and drug response through metabolic pathways.

The team has linked 145 genetic regions with more than 400 molecules involved in human metabolism in human blood. This atlas of genetic associations with metabolism provides many new opportunities to understand the molecular pathways underlying associations with common, complex diseases.

Metabolic molecules, known as metabolites, include a wide range of different molecules such as vitamins, lipids, carbohydrates and nucleotides. They make up parts of, or are the products of, all biological pathways. This new compendium of associations between genetic regions and metabolite levels provides a powerful tool to identify genes that could be used in drug and diagnostic tests for a wide range of metabolic disorders.

“The sheer wealth of biological information we have uncovered is extraordinary,” says Dr Nicole Soranzo, senior author from the Wellcome Trust Sanger Institute. “It’s exciting to think that researchers can now take this freely available information forward to better understand the molecular underpinnings of a vast range of metabolic associations.”

The team measured the levels of a large number of metabolites, both those already known and many as yet uncharacterised, from many different metabolic pathways.

They found 90 new genetic associations, trebling the figure of known genetic associations with metabolites. In many of the cases where metabolites were known, the team were able to link the molecule to gene function. They mapped genes to their likely substrates or products and linked these to a number of conditions, including hypertension, cardiovascular disease and diabetes.

They further found that these genetic regions map preferentially to genes that are currently targeted in drug-development programmes. This provides new opportunities to assess genetic influences on drug response, and to assess the potential for existing drugs to treat a wide range of diseases.

Hundreds of French students and teachers DNA tested to find rapist

Posted: April 14, 2014 at 1:51 pm

Students received their summonses last week.

Permission to take DNA samples requires the double consent of pupils and their parents, however refusal to agree to provide samples would be viewed as suspect and could be held for questioning, police said.

Most pupils were apparently happy to take part in the exercise but some said they regretted not being informed of the rape until several months after the attack.

Isabelle Pagenelle, the local prosecutor, said: Forty samples will be taken per hour, under the watch of teachers when it comes to pupils, as photos and identity cards are not always trustworthy for minors.

On the delay in conducting the tests and informing pupils, she said: We first needed to be sure about the girls credibility, then look for DNA traces on clothes, check these didnt belong to relations and compare them with the national genetic print database.

Only when this produced no leads did they decide to proceed with the mass test. It was chosen to avoid any repeat offence and to safeguard the school, she said, conceding that investigators could not totally rule out the possibility that the assault was carried out by an unknown intruder with no links to the school.

However, given its quasi-compulsory nature, the genetic testing of teenagers has come in for criticism.

“I understand the argument that those who have done nothing wrong have no reason to refuse. But why should refusal be considered an admission of guilt?” said Pierre Tartakowsky, president of the French human rights league. The exercise was “disproportionate, threatening and traumatising”, he told Le Parisien.

However Cathy Richert, a legal expert, said: Its obviously less traumatic to say that everyone is taking a DNA test than singling out certain people who risk being stigmatised.

The school has set up a counselling unit to provide psychological help if needed.
