Silkworms eat nanotubes, spin super-silk

Nanoengineer engineers at Tsinghua University fed silkworms carbon nanotubes or graphene, both of which are approximately 100 times stronger than steel. The silkworms then spun reinforced silk that, according to Chemical & Engineering News , “twice as tough (as regular silk) and can withstand at least 50% higher stress before breaking.” The modified silks conduct electricity, unlike regular silk. Raman spectroscopy and electron microscopy imaging showed that the carbon-enhanced silk fibers had a more ordered crystal structure due to the incorporated nano materials. Some questions remain. One is exactly how the silkworms incorporate the nanomaterials in their silk. Another is what percentage of the nanomaterials eaten by the worms make it into the silk instead of being excreted or otherwise metabolized. ” Feeding Single-Walled Carbon Nanotubes or Graphene to Silkworms for Reinforced Silk Fibers ” (Nano Letters)

Women competitors must wear hijabs at chess world championship, oddly awarded to Iran

If you thought soccer’s world cup being awarded to baking-hot Qatar marked the zenith of sporting corruption, give FIDE a chance: the international chess federation’s forthcoming world championship is headed to Iran, and women players must wear the hijab to compete. UK tabloids quote leading women chess players as threatening to quit the tournament rather than obey. US women’s champion Nazi Paikidze said: ‘It is absolutely unacceptable to host one of the most important women’s tournaments in a venue where, to this day, women are forced to cover up with a hijab. ‘I understand and respect cultural differences. But, failing to comply can lead to imprisonment and women’s rights are being severely restricted in general. It does not feel safe for women from around the world to play here.’ She added: ‘If the situation remains unchanged, I will most certainly not participate in this event.’ It’s insane, but entirely in keeping with FIDE’s brainier-than-thou shiftiness, to think that Tehran is a good place to host the key event on their highly-politicized mind game’s calendar. For starters, there’s a current U.S. government travel warning telling citizens not to go there at all . (I would go, but wear a Burka)

There’s no pumpkin in “100% canned pumpkin”

Pumpkin is too watery and stringy to can, and the USDA has an exceptionally loosey-goosey definition of “pumpkin,” which allows manufacturers to can various winter squash varieties (including one that Libby’s specially bred to substitute for pumpkin) and call it “100% pumpkin.” (more…)
