If you’re one of the nation’s experts on spiders and the properties of their silk, you best not have a hint of arachnophobia. Fortunately for us UC Riverside’s evolutionary biologist Cheryl Hayashi does not have this problem. 
We had the pleasure of interviewing Hayashi in the past and she told us then that one of the spider silk proteins they genetically sequenced dated back about 250 million years.

That’s a really long period of time. I mean, we’re going back to the Mesozoic, when dinosaurs are walking around. And so this is a long time for these sequences to be conserved. And to us, that argues that these regions of the sequence are probably very important for the functioning of spider silks.

Hayashi explained that there’s lots of interest in creating synthetic spider silks.

Spider silk is very strong and very tough. It actually surpasses a lot of the common man-made materials. It’s stronger than high tensile steel and has a toughness that is greater than Kevlar. So there’s a lot of interest in being able to mass produce spider silk.

You just never know who you’re going to meet ….

At a restaurant about a year ago, we happened to be seated next to a like-minded foodie and began a conversation about what was on our plates. Turns out that person was UCLA’s Amy Rowat, an integrated biologist who has been making a lot of waves with her innovative scienceandfood program. Our ucresearch production team made sure to look her up during a SoCal trip.
