Researchers Demonstrate Possible Primitive Mechanism of Chemical Info Self-Replication

When scientists think about the replication of information in chemistry, they usually have in mind something akin to what happens in living organisms when DNA gets copied: a double-stranded molecule that contains sequence information makes two new copies of the molecule. But researchers at Caltech have now shown that a different mechanism can also be used to copy sequence information. 

Better, Stronger, Lighter Armor

Caltech engineers and applied scientists are poking, prodding, and modeling materials on all scales to develop the understanding needed to build the next generation of armor. As part of a newly-funded Army collaboration, six Caltech researchers will investigate what happens to protective materials during intense impact.

Ditch Day 2012

One day each spring, kept secret until the last minute, seniors ditch their classes and vanish from campus, leaving behind complex, imaginative scavenger hunts, mazes, puzzles, and other challenges that are carefully planned out to occupy the underclassmen—preventing them from wreaking havoc in the seniors' rooms. Take a look at this year's shenanigans on Flickr, Facebook, and Twitter!
