Nanoscience is Out of the Bottle

 SUPER GOO: Nanotech and Super Heroes? It's a natural. A nanoscale adhesive, developed by University of Manchester researchers, lets this Spiderman hang with confidence. (Reprinted with permission from Nature Materials, 2:461-63, 2003) Don't look now, but the nanotech revolution is already here. It began as a collection of curiosities: nano-enabled sunscreens, tennis racquets, fishing rods, and stain-resistant pants. And more are coming. Nanotech supporters say the technology will benef

"Science... is good for the scientist; whether also for the rest of humanity is arguable." Erwin Chargaff Recently, a headline in the UK newspaper The Sun screamed "Your Mother Was Aborted Baby." The story dealt with the possibility of using aborted fetuses as a new source of donor eggs for couples needing fertility treatment. In the same week, the headline "Test-tube 'Monster' Condemned" ran in several publications, dealing with the creation of chimeric human embryos, part-male and part-f

As a lab rat, menial, lab slave, etc. for 20 years, I got incredibly tired of the demeaning attitudes by the supposedly better-educated grad students, postdocs, and professors. I was always professional in my work and gave 200% at all times.

In many species, the female attacks and eats its mate, and sometimes, the male offers itself as a morsel for the female to feast on after mating. But the male Argiope aurantia takes this to the extreme by spontaneously dying during copulation.1 It's not fatal attraction, but a smart way to protect paternal investment, says Daphne Fairbairn, University of California, Riverside.

PrPs exist in two forms: a common, harmless alpha-helical form, and a rare beta-sheet form that causes fatal mammalian brain diseases such as scrapie, Creutzfeld-Jacob disease, and mad cow disease. Prion diseases collectively are called spongiform encephalopathies, causing sponge-like vacuoles in

They even copulate. But the Y's lowly status has changed; now, it seems, the Y has been evolving, not dying, thanks to work by David Page and others at the
