Neuroscientists locate 'imaginary' colors
Researchers from the University of California, San Diego and the Salk Institute for Biological Studies have found that not only do grapheme-color synesthetes really see the colors they report, as measured in behavioral tests, but fMRI scans of their brains also show activation in the color-selective regions of the cortex when they view black-and-white letters or numbers.

African students get web link to MIT labs

UCLA researchers first to capture elusive lightning-quick waveforms
Researchers at UCLA have for the first time been able to capture and digitize electrical signals at the rate of 1 trillion times per second, a discovery that eventually may help scientists develop defenses against high-powered microwave weapons attacks and allow physicists to peer into the fundamental building blocks of nature.

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed
New research using a thousand-meter ice core shows a key section of the West Antarctic Ice Sheet probably never contained as much ice as scientists originally thought it did, so it couldn't have contributed as much as believed to higher sea levels 20,000 years ago.
