Biophiles D'abord un petit blabla (court, promis) sur ce site... Un site désiré... pourquoi ? Parce que cela faisait longtemps que je voulais le faire, tout proportion gardée... Mais s'il était déjà fortement désiré avant le début de son élaboration, il l'a été d'autant plus pendant sa construction car, n'ayant pas du tout l'âme informaticienne (et encore moins webmestrine) j'en ai un peu, beaucoup, bavé pour le faire ... Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.
Scientists Work To Unravel Mystery Behind Woman Who Doesn’t Grow Twenty year old Brooke Greenberg hasn’t grown since age five. For the last 15 years mystified doctors have been unable to explain the cause for Brooke’s disorder that has kept her aging in check. At age twenty, she maintains the physical and mental appearance of a toddler. Eric Shadt wants to solve this most bizarre of medical mysteries. Before DNA, before RNA: Life in the hodge-podge world - life - 08 January 2012 Take note, DNA and RNA: it's not all about you. Life on Earth may have begun with a splash of TNA – a different kind of genetic material altogether. Because RNA can do many things at once, those studying the origins of life have long thought that it was the first genetic material.
Accueil - Biologie et Multimedia Biologie Cellulaire Biochimie Biologie du Développement UK BAP The UK Biodiversity Action Plan (UK BAP) was published back in 1994, and was the UK Government’s response to the Convention on Biological Diversity (CBD), which the UK signed up to in 1992 in Rio de Janeiro. The UK was the first country to produce a national biodiversity action plan, and the UK BAP described the biological resources of the UK and provided detailed plans for conservation of these resources. Action plans for the most threatened species and habitats were set out to aid recovery, and national reports, produced every three- to five-years, showed how the UK BAP was contributing to the UK’s progress towards the significant reduction of biodiversity loss called for by the CBD. To support the work of the UK BAP, the UK BAP website was created by JNCC in 2001. The website contained information on the BAP process, hosted all relevant documents, and provided news and relevant updates.
The Biology Corner British scientists recreate the molecules that gave birth to life itself By Nick Enoch Updated: 08:03 GMT, 27 January 2012 Organic chemists at the University of York have recreated a pair of simple sugars - threose and erythrose - in a process which could have occurred before the advent of life Scientists are one step closer to understanding the origin of life after making a breakthrough into how sugar molecules found in DNA are created.
Portail BioMedia-UPMC Le service BioMédia au sein de la Faculté de Biologie (UFR 927), développe et facilite les interactions entre les biologistes et les nouvelles technologies de l'information. Nous créons, également, des ressources et des documents interactifs pour les étudiants et les enseignants de biologie. En accord avec le CPM, notre équipe gère les sites de mention "Licence SdV" et "Master bmc" en étroite collaboration avec les Directeurs des études.
Dragonflies keeping their eyes on the prize One of the things I love most about science blogging is the opportunity to learn about entirely new things. Of course, we all have that opportunity on most days, but having to find something to blog about three times a week definitely keeps me on my toes. And what I learn can be so fascinating! Often it’s about barnacle sperm or the evo psych of romance novels, but there are other, safe for work kinds of fascination, too! Marine Cyanobacteria Shed Billions of DNA-Containing Vesicles Scientists have recently discovered and documented the first extracellular, DNA-containing vesicles shed by ocean microbes. The marine cyanobacteria – photosynthesizing, prokaryotic bacteria that are ubiquitous to most terrestrial and aquatic habitats – are involved in Earth’s biogeochemical and nutrient cycles. During photosynthesis, the bacteria harness sunlight to convert light energy into chemical energy, using carbon dioxide and water and releasing molecular oxygen as a byproduct. Essentially, they provide a source of nourishment for other organisms, constituting an edible form of biomass. Scientists at the Massachusetts Institute of Technology (MIT) have discovered another potential role of cyanobacteria. They have confirmed that the bacteria manufacture and release tiny spherical packages containing a host of substances, including genetic material – which can be transferred via horizontal gene transfer – and nutrients.
