Hi Nigel.
Space rocks made into beads 2000 years ago and then transported 700 km only to be buried in the ground. I like the progression accruing of knowledge in this story. I mean, it's no surprise that major trade happened in that time, but it's nice having evidence of where and how far.
UC Berkeley researchers find there are some common plant chemicals that shut down the rotor motor (Catsper) for sperm tails. Potential for new contraceptives?
By complete chance, the Chicxulub asteroid could not have impacted a worse place for the biosphere. A few minutes difference would have been ocean, either way, which probably wouldn't have blocked the sun for weeks or more, and we'd probably still be rodent sized. On second thought, maybe chance was in our favor?
