Evolutionary biologists at Northumbria University have used science to figure out "attractive human dance moves" that demonstrate optimum genotypic and phenotypic health to prospective mates. "Cutting-edge motion capture technology" was used to record good and bad dancing. (Technoviking was reportedly unpleased.)
The Thoreau Poison - Caleb Crain of The New Yorker takes a closer look at the ideas explored in Upstream Color (spoilers)
The Olympus Microscopy Resource Center digital video gallery, with: live cells, pond life and more, crystals and more.
Celebrate the 60th anniversary of the discovery of DNA's structure with a pictorial story behind DNA's double helix and the Rosalind Franklin papers, including correspondences and lab notes that detail some of her crystallography research, findings that laid the groundwork for Watson and Crick's later publication.
After a decade or so of legal back-and-forth between Utah-based Myriad Genetics and medical researchers, the ACLU, and the Public Patent Forum, the US Supreme Court will hear a case next week which attempts to address whether genes — isolated (derivative) or original — can be patented. The stakes are high on both sides: opponents use Myriad's actions to argue that giving short-term monopoly control over humanity's genetic constituency is not in the public interest, while proponents defend the use of patents to spur private research in biotech, alternative energy and other nascent industries.

These days, it's easy to take visualizations of biological molecules for granted, what with the easy availability of an ever-increasing supply of high-resolution X-ray and neutron crystallography data, as well as freely available software that render them into beautiful and useful images that help us understand how life works. The lack of computers and computer networks in the mid-1950s made creating these illustrations a painstaking collaboration, requiring an artist's craftsmanship and aesthetic sense, as well as, most importantly, the critical ability to visualize the concepts that scientists wish to communicate. One such scientific artist was Irving Geis, who painted the first biological macromolecule obtained through X-ray data: an iconic watercolor representation of the structure of sperm whale myoglobin, as seen in the third slide of this slideshow of selected pieces. His first effort was a revolutionary work of informatics, including coloring and shading effects that emphasized important structural and functional features of the myoglobin protein, simultaneously moving the less-important aspects into the background, all while stressing simplicity and beauty throughout. The techniques that Geis developed in this and subsequent works influenced the standards for basic 2D protein visualization that are used today.
Omes have a long history and describe general interactions of biological information objects in various omes. But not all omes are real omes. Some have a problem with omes as neologisms.
A hive plot (slides) is a beautiful and compelling way to visualize multiple, complex networks, without resorting to "hairball" graphs that are often difficult to qualitatively compare and contrast. [more inside]
With the passing of Executive Order 13505, Removing Barriers to Responsible Scientific Research Involving Human Stem Cells, in 2009 President Obama expanded federal funding and rescinded George W. Bush's policies that eliminated most federal funding and restricted human embryonic stem cell research to the use of existing, contaminated cell lines. On Monday, federal judge Royce C. Lamberth blocked this new order after protestations from James L. Sherley, a former scientist with the Boston Biomedical Research Institute, and Theresa Deisher, who operates the Ave Maria Biotechnology Company, which aims to do "pro-life" therapeutic research without the "taint of embryonic or electively aborted fetal materials".

Neandertals are the closest ancestral relatives to modern humans. Today, Nature published a special report on the Neandertal genome, for which a draft sequencing of three billion nucleotides has been completed. This high-throughput sequencing project shows how the genetic relationship between Neandertals and modern Europeans and Asians suggests localized interbreeding between the two species roughly 40-80,000 years ago, complicating the common "out-of-Africa" story of how modern humans originated. Additional research extends this low-coverage, first-pass sequencing with a microarray approach that uncovers specific differences between the human and Neandertal genomes.
Meet three new species of Loricifera, the first multicellular forms of life found that can live entirely without oxygen (figures and full article, PDF). [more inside]
North American Insects and Spiders - 7000+ close-ups of wolf spiders, black widows, honeybees, a ladybug eating an aphid, gulf fritillary butterflies, praying mantises, and much, much more
"Algae is the ultimate biological system using sunlight to capture and convert carbon dioxide into fuel... I came up with a notion to trick algae into pumping more [fuel] out." Craig Venter's Synthetic Genomics partners with ExxonMobil in a $600M project to harvest biofuels from genetically engineered algae. "We have modest goals of replacing the whole petrochemical industry." [previously] [more inside]
Journal of Visualized Experiments (JoVE) is the first video journal for biological research accepted in PubMed, featuring hundreds of peer-reviewed video-protocols demonstrating experimental techniques in the fields of neuroscience, cellular biology, developmental biology, immunology, bioengineering, microbiology and plant biology, free of charge.
Carl Zimmer's Science Tattoo Emporium - "Underneath their sober lab coats and flannel shirts, scientists hide images of their scientific passions. Here they are revealed to all." From the science journalist and writer responsible for The Loom and numerous other published works.
Bonobo chimpanzees are commonly thought to be "an example of amicability, sensitivity and, well, humaneness" in the animal kingdom. Ian Parker's Swingers suggests a darker, more savage side to the species that belies popular perception.
"Nothing in biology makes sense except in light of evolution." Despite Theodosius Dobzhansky's succint description of natural selection at the core of biological research since Darwin's fateful trip to the Galapagos, evolutionary biologist Michael Lynch respectfully dissents, asking "whether natural selection is a necessary or sufficient force to explain" the complexity of multicellular organisms we see today, where mutation, recombination and genetic drift are often overlooked, but critical factors in evolutionary theory and understanding.
In their own words... Researchers at the National Institutes of Health recall the early years of AIDS, from diagnosis of the then-unknown disease, to discovering the viral cause, and from there to the search for treatments. The site features interviews (including several with virologist Robert Gallo), early publications, and a collection of archived image materials.
The University of Washington CSE Colloquium features accessible talks by leading computer scientists and computer engineers from the University of Washington, the region, the nation, and the world, most of which are available as MP3 audio and/or Real/Windows Media video online for free. Personal favorites include talks on quantum computing, de novo protein design, and in silico biology as a smarter way to learn how our genes work.
Among his collected works, in the few, short years before mathematician Alan Turing was driven to suicide, he published "The Chemical Basis of Morphogenesis", theorizing how a standing wave-like distribution of "cannibal" and "missionary" chemicals might explain how plants and animals develop their shape and pigmentation. Blogger Jonathan Swinton focuses on this more obscure aspect of Turing's research, and reviews some of his posthumous and unpublished efforts — including one of the earliest known examples of digital computation applied to the field of biology.
