  1. IMAGES: Go with the Flow

    It isn't a fancy Rorschach blot or a computed tomography scan of the intestines. Instead, the image “Chaotic Mixing in Viscous Fluids” depicts the chaotic mixing caused by stirring a vat of glycerin and fluorescent dye. It's one example of liquid artistry on display at this gallery* from the journal Physics of Fluids. Showcased here are winning entries from the American Physical Society's annual exhibition of videos and photos. You can admire shots from as far back as 1985, although you'll need a journal subscription to see the newest entries. This fluid dynamics collection from applied mathematician John Bush of the Massachusetts Institute of Technology uses a strobe lamp and other tricks to reveal unexpected and striking patterns, such as the trail of turbulence created by a water strider.

  2. EXHIBIT: Milky Way Portraitist

    Staying up late paid off for American astronomer Edward Emerson Barnard (1857–1923). Dubbed “the man who never slept,” the telescope virtuoso took gorgeous photos of our galaxy, such as the nebula of Rho Ophiuchi, and discovered a slew of heavenly objects, including Jupiter's fifth moon Amalthea. At this exhibit from the Georgia Institute of Technology in Atlanta, you can peruse Barnard's magnum opus, the posthumously published Atlas of Selected Regions of the Milky Way. Although he left school at age 9, the self-taught observer rose to be a professor at the University of Chicago and sat at the controls of the world's largest telescopes. Astronomers still value the atlas for its wide-angle views and because it revealed murky areas in space that eventually led to the discovery of dark matter.

  3. WEB LOGS: Small News

    Microbe fans can get an eyeful of viruses or an earful of bacteria at the new educational Web log Microbiology Bytes from Alan Cann of the University of Leicester in the U.K. Along with written commentary, Cann offers excursions into the microbial world in the form of enhanced podcasts, which feature video and graphics as well as audio narration. Podcast topics include determining how many bacterial species dwell in the soil and recent studies on the use of RNA interference to block cold sores.

  4. DATABASE: Framingham Gene Hunt

    The race to find the genes behind common ailments is heating up as many research groups scan patients' entire genomes for markers linked to disease. When it opens later this month, the Genomic Medicine Database (GMED) from Boston University (BU) will showcase such results from 1320 participants in the famed Framingham Heart Study, which has followed the health of a small Massachusetts town for 50 years. You can peruse the chromosomes for possible associations between about 10 traits—such as hypertension and high cholesterol levels—and 100,000 genetic markers, known as SNPs. Click to zoom in on the genes near a SNP. The BU team is posting data before publication so that other researchers can quickly seek to replicate the findings, says GMED co-curator Marc Lenburg. “Our hope is that others will follow our lead” and share unpublished data, he says.

  5. RESOURCES: Flu on the Wing

    This new avian influenza monitoring site houses no data on the highly pathogenic H5N1 virus in U.S. wild birds—but that's a good thing. As the U.S. Geological Survey clearinghouse records, none of the more than 11,800 birds sampled in 28 states so far this year carried the virulent strain, which experts fear could morph into a virus that triggers a pandemic. If the deadly virus does infect wild birds here, as it has done in Asia and Europe, visitors will be able to follow the results state by state.
