Understanding Evolution

Biology Animations Carnegie Mellon's Office of Technology for Education and Department of Biological Sciences create multimedia materials for teaching and learning Biology. After an analysis of a number of Biology courses was performed to identify when and how shared concepts where taught, a team of biologists, media programmers, and learning experts came together to create animations designed to improve understanding of some of the main concepts taught in Modern Biology and Biochemistry. Phosopholipid Membranes Tutorial page describing the construction and properties of Biological Membranes. Biological Membranes Biological membranes are dynamic structures composed of a diverse set of phospholipid molecules and proteins. Phase Transition This tutorial explains how phospholipids bilayers undergo to a cooperative phase transition or melting that is similar to protein denaturation. back to index Signal Transdaction Serine Protease Uniport - Glucose Transport Symport - Lactose Permease Transporter ATP Synthesis

Evolutionary origins of the nervous system - Neurophilosophy THE human brain is a true marvel of nature. This jelly-like 1.5kg mass inside our skulls, containing hundreds of billions of cells which between them form something like a quadrillion connections, is responsible for our every action, emotion and thought. How did this remarkable and extraordinarily complex structure evolve? This question poses a huge challenge to researchers; brain evolution surely involved thousands of discrete, incremental steps, which occurred in the mists of deep time across hundreds of millions of years, and which we are unlikely to ever fully understand. Nevertheless, a number of studies published in recent years have begun to shed some light on the evolutionary origins of the nervous system, and provide clues to some of the earliest stages in the evolution of the human brain. The simplest nervous systems lack a brain, and instead consist of diffuse networks of nerves. “Such a complex arrangement could not have been invented twice throughout evolution. Related:

Espace des sciences - DARWin : la théorie de l'évolution et la génétique humaine - Introduction - Conférence - Questions du public A partir d'une approche historique de la façon dont ont été élaborées la théorie de l'évolution et celle de l'hérédité, on explorera les interactions complexes entre la biologie et la société. ENSI/SENSI: Evolution/Nat.of Sci.Home Page 19 February 2017 ATTENTION, FILMMAKERS! A chance to make a film about evolution and win a prize! Scientists and science educators of all stripes -- students, postdocs, faculty, and full- or part-time science communicators -- are invited to enter the Seventh Annual Evolution Video Competition, sponsored by the Duke Initiative for Science & Society, the Howard Hughes Medical Institute, the Society for the Study of Evolution, and the BEACON Center for the Study of Evolution in Action. To enter, please submit a video that explains a fun fact, key concept, compelling question, or exciting area of evolution research in three minutes or less. Entries may be related or unrelated to your own research, and should be suitable for use in a classroom. The finalists will be screened at the Evolution 2017 meeting in Portland, Oregon.

Evolution Extension: Hominoid Drawings The seven drawings available for downloading from this site, in PDF format, were drawn by Ryan Scott McCullar*, for Martin Nickels at Illinois State University. Each one is a full scale profile, identified, and with a metric ruler for convenience (and to confirm the scale). If you can use a laser printer (e.g. at your district office, school, or local library), your results should be of very good quality, although inkjet printouts should be quite usable. A fast internet connection would also facilitate your downloading success. Each drawing requires about 100K of memory, so, in order to speed up the download time, they are available separately, and must be downloaded as seven separate items. To retrieve each item, just click on its name (in dark blue print) below. *Scott McCullar is currently Professor of Art at Springfield College in Illinois.

Home of CELLS alive! Dispatches from the birth of the Universe: sometimes science gets lucky For the generations that grew up with TV before the age of cable, the box in our living room was a time machine, capable of taking us back to just a few hundred thousand years after the birth of the Universe. We just didn't realize it. Nor did the scientists that discovered this, at least at first. But luck seemed to play a large role in one of the biggest discoveries of our lifetime. That may not have been the intended message of the discussion called "Dispatches from the Birth of the Universe," hosted by the World Science Festival on Friday. The panel provided a good picture of our current state of knowledge on the birth of the Universe, and a glimpse at what we'll likely find out next. Lawrence Krauss, who moderated the panel, introduced it by turning on an old TV set on stage. But, even after the birth of television, nobody realized what it was. But the background they detected from Earth was smooth, while we know the Universe is lumpy, filled with complex structures. And Mather?

Posters | i-Biology | Reflections I quite like making posters (graphorisms, if you will), to collect up ideas from readings, articles, science and the like. I find orgnising the thoughts into something visual and attractive helps clarify them for myself and they add a splash fo colour to otherwise texty blogposts. I often attach them to tweets, and these tend to generate more interaction that text links alone. I usually use the Creative Commons search to find suitably-licensed Flickr images (if I don’t have my own). I edit them in GoogleSlides, using a partly-transparent text box at the bottom for citations and the ColorZilla Chrome colour picker add-on to match the colour palette. Sometimes I use ClippingMagic.com to remove backgrounds. Here are some recent posters. ……….o0O0o……….. If we reflect only backwards, we miss the possibilities of the journey ahead. “I forgot the word I wanted to say, and thought, unembodied, returns to the hall of shadows.” I like this quote, and have it up in my lab. ………..o0O0o………..
