Neurons: A Fish-Eye View of the Brain Speed-dating neurons make connections Researchers in the Smith lab have also been able to watch the development of single neurons as they grow and connect to each other to complete the optical system. What they’ve seen helps explain how the brain's enormous complexity emerges. It now appears that brain organization happens in stages. As a developing neuron grows, it sends out tiny exploratory branches called filopodia. These projections search for partners in an effort to make connections and form synapses. Once formed, the synapse becomes a hot spot; the connected neuron sends out new filopodia, thus increasing the number of connections it has with other neurons. The wiring process happens quickly: one filopodium explores for about five minutes, retracting if it doesn’t make any connections. Scientists used to believe that once an animal’s brain was wired up, the resulting network was final and no new connections were possible.
Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Carbon The size of the carbon atom is based on its van der Waals radius.

projects for Exclusively online Formal Verification is the process of rigorously analyzing software to detect flaws that make programs vulnerable to exploitation. Performing this analysis requires highly skilled engineers with extensive training and experience. This makes the verification process costly and relatively slow. The Defense Advanced Research Projects Agency (DARPA) Crowd Sourced Formal Verification (CSFV) program is interested in improving and advancing the current processes of formal verification by significantly increasing the number of people working on formal verification projects at any given time through crowd-sourcing. CSFV augments the intensive work done by formal verification experts by greatly decreasing the skill required to do formal verification. Much of the work required in the process of formal verification can be automated. CSFV seeks to add more human expertise to the process of formal verification through fun and engaging video games. The five teams involved in the project include:
Diversity In Nature :: SeenAndShared.com :: Best Quality! Diversity "Diversity is not about how we differ. Diversity is about embracing one another's uniqueness." - Ola Joseph "United we stand, divided we fall." - Aesop (620 -560 B.C.) "Diversity: the art of thinking independently together." - Malcom Forbes "Love the one you're with." - Stephen Stills "Diversity is the magic. The greater the diversity, the greater the perfection." - Thomas Berry "We are eternally linked not just to each other but our environment." - Herbie Hancock "We cannot afford to be separate. . . . "I know there is strength in the differences between us. "Uniformity is not nature's way; diversity is nature's way." - Vandana Shiva "Share our similarities, celebrate our differences." - M.
