Andrew Maynard is a scientist and emerging technology adviser.
He blogs at 2020 Science and tweets as @2020science. Some of the most entertaining, informative and mind-blowing science videos on the web come from TED – the Technology, Entertainment, Design conference. Challenged to give the “talk of their lives,” the world’s top scientists and science communicators have been dazzling audiences – many of whom are thought leaders, trend-setters and entertainers - for years now. Most of the best talks are now freely available on the internet, but sifting through hundreds of video clips to find the real gems can be hard going.
To make things easier, here are five of my favorite TED Talks on science. Timeline - Chemical Scientific Discovery. Ask a Scientist Index Directory. Lune. A lune is a plane figure bounded by two circular arcs of unequal radii, i.e., a crescent.
Biochem4schools: Search by topic. Visual Calculus. Algorithm Tutorials. Have we found the universe that existed before the Big Bang? First of all, let me say that this is not a comment on the overall article, but a small portion of it included below.
I stopped reading at the line "it's not clear whether one can even use the term "before" in reference to a pre-Big-Bang cosmos, as time itself may not have existed yet" There is no such thing as "time" as we see it. Quantum Physics: David Bohm. Bohmian Wave Mechanics, Holographic Universe, Bohm Biography. Introductory Quotes to David Bohm's Holographic Universe It is proposed that the widespread and pervasive distinctions between people (race, nation, family, profession, etc., etc.) which are now preventing mankind from working together for the common good, and indeed, even for survival, have one of the key factors of their origin in a kind of thought that treats things as inherently divided, disconnected, and "broken up" into yet smaller constituent parts.
Each part is considered to be essentially independent and self-existent. (David Bohm, Wholeness and the Implicate Order) The notion that all these fragments is separately existent is evidently an illusion, and this illusion cannot do other than lead to endless conflict and confusion. Indeed, the attempt to live according to the notion that the fragments are really separate is, in essence, what has led to the growing series of extremely urgent crises that is confronting us today. Robert Lanza, M.D.: Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone. Recent discoveries require us to rethink our understanding of history.
"The histories of the universe," said renowned physicist Stephen Hawking "depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history.

The History of Mathematics - BBC doc (part1) The Secret Life of Chaos Part (1 - 6) DNA Interactive. Traits of Life: Exhibits. Protein Data Bank. A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease.
As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states. Top 10 Amazing Biology Videos. Cyborgs, stem cells, glowing mice, and hilarious music videos are great reasons to be excited about biology.
Here are some of our favorite clips from the life sciences. 10. Immune Cell Chasing a BacteriumIt may look like the predecessor to Pac Man, but this vintage clip shows a neutrophil wending its way through a crowd of red blood cells to destroy its bacterial nemesis. 9. How High Speed Gene Sequencing Works Within the next few years, Helicos BioSciences may be able to read an entire human genome for under one thousand dollars. Plus Magazine. Physicsworld.com. Early stress alters epigenome. Scientists have figured out how stress experienced early in life can cause long-lasting changes in physiology and behavior -- via epigenetics.
Image: Max-Planck Institute of Psychiatry, MunichSpecifically, early stress appears to induce epigenetic changes in a specific regulatory region of the genome, affecting the expression of a hormone important in controlling mood and cognition into adulthood, according to a study published online today (November 8) in Nature Neuroscience. Everywhere in a Flash: The Quantum Physics of Photosynthesis. By hitting single molecules with quadrillionth-of-a-second laser pulses, scientists have revealed the quantum physics underlying photosynthesis, the process used by plants and bacteria to capture light’s energy at efficiencies unapproached by human engineers.
The quantum wizardry appears to occur in each of a photosynthetic cell’s millions of antenna proteins. These route energy from electrons spinning in photon-sensitive molecules to nearby reaction-center proteins, which convert it to cell-driving charges. Almost no energy is lost in between.
