Solar-powered sea slug harnesses stolen plant genes - life - 24 November 2008 Video: Watch a sea slug eat algae to nab some of its chloroplasts, and the genes that keep them functioning It's the ultimate form of solar power: eat a plant, become photosynthetic. Now researchers have found how one animal does just that. Elysia chlorotica is a lurid green sea slug, with a gelatinous leaf-shaped body, that lives along the Atlantic seaboard of the US. What sets it apart from most other sea slugs is its ability to run on solar power. Mary Rumpho of the University of Maine, is an expert on E. chlorotica and has now discovered how the sea slug gets this ability: it photosynthesises with genes "stolen" from the algae it eats.

Lucie Lt Reconstitution d'un paysage ancien La région Charolaise au Trias était quelque peu différente de ce que l’on connait aujourd’hui : de vastes plateformes lagunaires voyaient s’ébattre quelques dinosauriens de bonne compagnie là où s’ébrouent actuellement les vaches blanches mondialement connues. Un ensemble d’indices sédimentologiques relevés dans une ancienne carrière permet de reconstruire progressivement le paysage et le climat de l’époque, dans une démarche basée sur le principe d’actualisme. Le site présente des photographies des indices relevés, des photographies d’indices actuels comparables, avec les mécanismes qui en sont à l’origine, et des pages résumant "ce que cela nous apprend". Cette activité permet de développer les compétences : prise d’informations simultanée dans des documents de natures différentes (texte et image), mise en relation de données issues de documents différents.

About canning food Endurance exercise 'interferes with heart rhythm' Pascaline Athletes beware - endurance training may make it more likely that you will need a pacemaker, scientists believe. A British Heart Foundation team found exercise in mice triggers molecular changes in the part of the heart that generates its natural beating rhythm. This may explain why elite athletes have low resting heart rates and more risk of heart rhythm disturbances, they told Nature Communications. However, the benefits of exercising still outweigh any risks, experts say. Super-fit Endurance athletes are generally very fit.

Pascaline On your bike: how muscles respond to exercise ​We all know that exercise makes us fitter and healthier – but what changes take place in our cells to make this happen? Next time you are working out in the gym, or pounding the streets running or jogging, ponder this: the idea of ‘muscle memory’ – that today’s exercise has effects on our muscles years from now – has never been demonstrated scientifically. Does it really exist, and if so, how does it work? These are some of the questions we hope to answer in our on-going research, which aims to pin down the changes that occur in muscles when we exercise, and how our muscles ‘know’ to respond differently to, say, endurance training as opposed to strength training.
