Earth from Above a collection of aerial photography "Earth From Above" is the result of the aerial photographer Yann Arthus-Bertrand's five-year airborne odyssey across six continents. It's a spectacular presentation of large scale photographs of astonishing natural landscapes. Every stunning aerial photograph tells a story about our changing planet.

Molecular Expressions Microscopy Primer: Introduction to Microscopy Introduction to Optical Microscopy,Digital Imaging, and Photomicrography This treatise on optical microscopy is divided into several sections that are available through the links displayed immediately to the left (in the darker navigational boxes) and below. In order to print the entire microscopy primer as a paper document, you must download each link independently, send the file to your printer, and put the results together. In the Bibliography, we have included links to other works on optical microscopy and our section on Web Resources contains links to other microscopy sites on the Internet. Frequently Asked Questions - Mortimer Abramowitz, senior microscopist at Olympus America Inc., answers the 50 most commonly asked questions about microscopy and photomicrography. Concepts and Formulas in Microscopy - Many of the basic concepts in optical microscopy can be distilled into a few rules and formulas. Innovations in Light Microscopy - Noted microscopist and author Martin L.

Cell Cycle & Cytokinesis - Cell Cycle Regulation and the Control of Cell Proliferation (Cell Growth + Cell Division) Cell Cycle Research - General resource with links to relevant recent literature, news and job listings. (Ion Channel Media Group) Cell Division - Undergraduate-level lectures on cell division. See also the Apoptosis, Cell Senescence and Signal Transduction pages. Mitosis, Meiosis and the Mechanics of Cell Division See also the Cytoskeleton, Cell Motility and Motors page. Cancer Resources A major component of cancer progression is the loss of normal controls on cell proliferation (disruption of normal cell cycle regulation and cell signaling), in addition to other changes involving angiogenesis, cell adhesion, invasion and metastasis.

Urban Renewal by Mari Santos We're usually kinda "meh" about most T-shirt surgeries because we're just can't get into the hack'em, slash'em sartorial school of thought. Toronto-based Mari Santos, on the other hand, is such a genius with a pair of scissors we want to hitchhike across the border, kidnap her, head back south, and then set her to work against her will on the oversize T-shirts we seem to get for free by the pound. Except that it would probably be illegal. Her ethos: "Taking something old, frumpy and ill fitting and making it into something new." More pictures below the fold.

Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. It covers the nuclei deep within the cerebral hemisphere e.g. the basal ganglia; the structure called the thalamus, and the ‘white matter’, which consists mostly of myelinated axons. – closely packed neuron cell bodies form the grey matter of the brain. Cerebellum – responsible for psychomotor function, the cerebellum co-ordinates sensory input from the inner ear and the muscles to provide accurate control of position and movement.

Cloning & Synthetic Biology Overview of Traditional Cloning Traditional Cloning refers to the generation of DNA fragments using restriction enzymes, and their subsequent assembly and transformation. The name is derived from the method’s history as the first widely-accepted cloning method. scroll to see additional videos

Des bactéries qui ne perdent pas le Nord Certaines bactéries aquatiques ont inventé et utilisé la boussole quelques millions d’années avant les Chinois. Comment biologiquement ces bactéries fonctionnent-elles et à quoi ça leur sert ? Mon histoire commence au milieu des années 70 avec un jeune étudiant en thèse, Richard Blakemore, qui étudiait des populations de bactéries que l’on trouve dans les boues et sédiments au fond des océans, des lacs ou des marais. La grande inspiration de Blakemore, peut-être intrigué par la constance du mouvement, fut de répéter l’observation en différents endroits ou en changeant l’orientation du microscope, et les bactéries continuaient de nager dans la même direction, non par rapport à la lame, mais par rapport au laboratoire! Il existe donc des bactéries « magnétotactiques » dotées de la faculté de sentir les champs magnétiques, et au premier chef le champ magnétique terrestre.

Hobo Stove | Practical Survivor Urban survival is a tricky subject to discuss. There are advantages to urban survival. Anywhere you look there are items in trash cans and dumpsters that can be used to improve a survival situation. Cardboard boxes can be used for shelter, newspapers can be used for insulation and to the practical survivor another persons trash can be a treasure. In this case we will use a coffee can to build a stove. Keep an open mind during any survival situation. Whether backpacking, camping, or surviving, having a way to cook can make a huge difference. A coffee can or large vegetable/ravioli can will allow you to build a stove and cook. Items used to build this stove: * Coffee can * Can opener * Tin snips * Drill and drill bits * Metal coat hanger There are many methods that could be used to build this stove. We use a metal coat hanger to build rods which will help hold up the cooking pot. The top side of a coffee can is already opened. We then used the tin snips to cut a small door. Materials:
