Le Tritordeum : Une nouvelle céréale bio, fruit du génie génétique. Le lancement d’un premier pain à base de tritordeum par les Établissements Moulin, spécialistes des « pains biologiques aux saveurs authentiques », n’a pas vraiment fait sensation.

Le Tritordeum : Une nouvelle céréale bio, fruit du génie génétique

Pourtant, que de belles promesses à en croire le site créé pour sa promotion ! « Le Tritordeum est une nouvelle céréale naturelle qui est née de la combinaison entre du blé dur (Triticum durum) et une orge sauvage (Hordeum chilense) originaire du Chili et de l’Argentine. Il s’agit de la première nouvelle céréale commercialisée dans le monde et apte pour la consommation humaine », explique Agrasys, la société espagnole aujourd’hui détentrice des droits exclusifs. Le discours est convenu, et les mots bien choisis pour rassurer le consommateur : « Les techniques de sélection qui ont été utilisées pour développer cette céréale sont des méthodes traditionnelles de croisement sur champs qui ne font pas appel à des modications génétiques.

Une naissance laborieuse. Faire des tests ADN avec son smartphone. Vous voulez vous la jouer "police scientifique" ?

Faire des tests ADN avec son smartphone

En avant pour la saison 1 des Experts Courbevoie. La société américaine Biomeme vous invite à faire des tests ADN sur tout ce qui vous entoure, sans avoir à passer par un laboratoire, grâce à un mini thermocycleur qui se greffe à votre iPhone. Vous êtes à la recherche d'un gène en particulier ? Vous effectuez un prélèvement (sur une plante, un poisson ou une vieille chaussette), vous l'insérez dans le dispositif et votre iPhone analyse le test. En gros, l'appareil duplique en grande quantité la séquence ADN que vous cherchez à identifier, à partir d'une réaction en chaîne. CRISPR gene edited cabbage grown and cooked for the first time. The cabbages were edited using CRISPR (Clustered regularly interspaced short palindromic repeats)-Cas9 technology to remove a segment of their DNA.

CRISPR gene edited cabbage grown and cooked for the first time

The changes – a deletion in the coding region – were expected to alter growing patterns, Umeå University’s Professor Stefan Jansson told FoodNavigator. CRISPR cabbage Credit: Stefan Jansson Professor Jansson – who grew, harvested and cooked the cabbages – was unable to confirm whether intended changes occurred since the seeds were modified in a lab in a different country which wishes to remain anonymous. However, after serving the cabbages to Gustaf Klarin, the host of a Radio Sweden gardening show, he said the project could be the first small step towards new opportunities in farming. “Although the meal only fed two people, it was still the first step towards a future where science can better provide farmers and consumers across the world with healthy, beautiful and hardy plants,” the university said in a statement.

EU legalities. UK Biobank launches world’s biggest body scanning project to shed new light on major diseases. The world’s largest health imaging study, funded by the Medical Research Council, EFC member the Wellcome Trust, and the British Heart Foundation was launched on the 14th April It will create the biggest collection of scans of internal organs, and transform the way scientists study a wide range of diseases, including dementia, arthritis, cancer, heart attacks and strokes.

The £40m study will involve imaging the brain, heart, bones, carotid arteries and abdominal fat of 100,000 current participants of UK Biobank, a visionary project set up in 2006 by the MRC and Wellcome Trust to create a research resource of half a million people across the UK to improve health. The multi-organ scans will be analysed alongside the vast data already collected from UK Biobank participants. Dr Sara Marshall, Head of Clinical Research at the Wellcome Trust, said: “Capturing such a vast number of images of the human body, in both health and illness, will chronicle disease in a way never attempted before. Nestlé puts €18m on table for epigenetics research. The company has been collaborating with the EpiGen Consortium – a public-private partnership made up of institutions from Southampton, Auckland and Singapore – since 2011.

Nestlé puts €18m on table for epigenetics research

Nestlé’s contributing scientists work from its research centre in Lausanne, Switzerland. The company said it hoped epigenetics, the study of how environmental factors including eating behaviours could impact genetics of the consumer and therefore future generations, would help it understand more about the importance of maternal nutrition. Chief technology officer for the firm Stefan Catsicas said it was particularly interested in the areas of pregnancy-related conditions such as gestational diabetes. Heiko Schipper, CEO of Nestlé Nutrition, said: “Science shows that the nutrition infants and young children receive in the first 1000 days from conception has a long-lasting influence on their health, wellness and quality of life.”
