New species discovered in Asia include a singing frog and a walking fish The World Wildlife Fund has a new report about recent new species discoveries in the Mekong Delta region, which encompasses Cambodia, Laos, Myanmar, Thailand, Vietnam, and a part of southern China. Here’s the thing — they’re, uh, they’re kind of advanced. Like, there’s a fish that walks on land, and a frog that composes music, and a lizard that walks on two legs, and a bat that suggests this is all because of some kind of demonic intervention. You can read the full report here [PDF], but meanwhile, here are our favorite demonstrations that the new animals of the Mekong Delta are a force to be reckoned with and possibly a harbinger of the End Times. Singing frog Anyone can croak, but male frogs of the species Graxicalus quangi sing songs to their beloveds instead. Walking catfish Clarias gracilentus looks kinda more like a slug than a fish in this photo, which is appropriate since it can walk on dry land. Two-legged lizard Devil bat

We hope that it is suitable for AP Biology students or for students of introductory anatomy and physiology at the college level. We have revised this site to improve the learning experience and accessibility. Within this site, you can navigate to any chapter from the links at the left. Kadolis- Tout pour le bébé - kadolis 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. Helping us to investigate these questions is a large team of volunteers. We assess the fitness of our volunteers before and after participation in the studies by measuring their maximal oxygen uptake. Of course, we already know that regular exercise produces health benefits. Building mitochondria Epigenetic factors Acknowledgement
272/ Lâcher prise : Grenouille rieuse (Rana ridibunda Pallas), Château de Saint-Victor des Oules, Gard, France, 21 juin 2012 "S'accrocher au connu, c'est rester prisonnier de l'ignorance."Yvon Rivard, écrivain canadien (1945- ) Lâcher prise Attiré par le croassement sonore des grenouilles de l'étang, je m'approche de l'eau calme en essayant de ne pas attirer l'attention de ses habitants bruyants. Mais quelques brindilles d'herbe froissée suffisent à les dissuader de continuer leur conversation animée. Sur une nappe de nénuphars, plusieurs grenouilles se hissent avec bien peu de grâce. Est-ce un roi transformé en grenouille ? Grenouille rieuse, si tu restes accroché ainsi tu risques de ne pas connaître l'étendue de la marre. Entre le risque de lâcher la proie pour l'ombre et l'enfoncement progressif dans le confort d'un microcosme connu, quel est le bon choix ? S'exposer à l'inconnu peut nous permettre de découvrir d'autres chemins - des impasses ? Le mouvement est nécessaire. La clé serait-elle donc dans une forme de certitude de l'incertain ? Pour ma part, je fuis les vérités absolues.
problème obésité : Persuasive Games -Fatworld (laura philippe) Fatworld is a game about the politics of nutrition. It explores the relationships between obesity, nutrition, and socioeconomics in the contemporary U.S. Fit or Fat? In the last two decades, obesity has soared in the United States. Public and private organizations have mounted ongoing efforts to change Americans’ behavior toward nutrition and exercise. More importantly, these efforts assume that our obesity crisis is caused solely by lack of self-control: if only everyone would choose to eat right and exercise, the problem would go away. Fatworld is a videogame about the politics of nutrition. Existing approaches to nutrition advocacy fail to communicate the aggregate effect of everyday health practices. You can choose starting weights and health conditions, including predispositions towards ailments like diabetes, heart disease, or food allergies. Interested in politics?
Falafels crus - GRENOUILLE CITADINE En ce moment, il faut bien avouer, le régime sans gluten ni produits laitiers me pèse un peu. Je rêverais de ne pas me prendre la tête en cuisine, de fonctionner sur mes vieux automatismes, de pouvoir dans la panique acheter des raviolis frais et les cuisiner en 2 minutes montre en main. Hélas je bataille toujours avec les compositions, jusqu'à découvrir que les falafels du rayon frais que je préférais entre tous contiennent du gluten ! Grmpf ! Donc du coup je suis à la recherche de LA bonne méthode pour les falafels maison, mais comme je ne suis pas du tout d'humeur culinaire, j'ai déjà raté mes deux premières séries - pour un résultat mangeable et congelable, mais trop sec. Pour la présentation, j'ai choisi de les rouler dans un mélange de poudre d'amande-gomasio-levure maltée (moui je sais y'a un poil de gluten, pas bien, mais la levure je suis trop accro), le résultat poudreux m'a paru très joli... et bon.
A Serious Game on Biodiversity in Wheat Farming | KTM Advance April 28, 2014 A Serious Game on Biodiversity in Wheat Farming Lu, the leading French cookie manufacturer, further confirmed its desire to minimize the company’s impact on the environment by creating LU Harmony. This new wheat network, created in partnership with French farmers, favors biodiversity and guarantees quality wheat farming. In 2010, KTM Advance created a serious game to allow young players to learn about the sustainable development LU defends and dive into the wheat field ecosystem. They also learn how to grow quality wheat and maintain local biodiversity. The “Harmonyculteurs,” or “Harmony Farmers,” deals with complex information in a fun and accessible way.

La grenouille verte Un peu après la ponte, l’œuf se développe. Il prend la forme d’un haricot dont l’un des côtés sera la tête et l’autre la queue. Une semaine après, un petit têtard sort de l’œuf. Le têtard a une ventouse à la place des yeux et de la bouche qui lui permet de se fixer aux plantes. Deux ou trois jours après, la ventouse disparaît pour laisser place aux yeux et à la bouche. Ensuite, deux pattes en forme de palmes vont remplacer la queue. Ses yeux grossissent de plus en plus et le têtard se transforme en grenouille.
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. Yet, paradoxically, they are more likely to have heart rhythm disturbances, known as arrhythmias, especially as they get older - although the risk is still small. Experts have suspected that this is because long-term training for extreme endurance events such as marathons and triathlons slows the heartbeat down. Cyclists Sir Chris Hoy and Miguel Indurain reportedly had resting heart rates of 30 and 28 beats per minute. How to exercise
