Things I have recently spotted that may be of interest to someone else:
How to observe the sun for yourself.
Honda has created a robot that can act in response to the brain activity of a person, whose brain is read by an MRI. It's not ready for prime time yet.
Are RFID chips, implanted in humans, the mark of the Beast?
Article on MSNBC (therefore more or less for the general public) on extra dimensions, and possible proof that they exist. (Also shows that physicists aren't just old Caucasian males in white lab coats -- see the photos of the scientists interviewed.)
When I don't tell where I found an item above, I either found it directly, or was probably pointed to it by the Librarian's Internet Index, SciTech Daily, or Arts and Letters Daily. All of them are great.
