RESTON, Virginia, August 11, 2010 -- comScore, Inc. , a leader in measuring the digital world, today released a report on Twitter.com growth worldwide. The study found that in June, nearly 93 million Internet users visited Twitter.com, an increase of 109 percent from the previous year, as the social networking site achieved strong gains across all global regions. Indonesia reported the highest penetration, with 20.8 percent of Internet users in the country visiting Twitter.com that month, followed by Brazil and Venezuela, with Venezuela's growth fueled in large part by Venezuelan President Hugo Chavez's decision to join Twitter in late April. 

Some people can sleep through a Who concert while others wake up if a mouse in the yard moves.   A new report in Current Biology says the difference is that sound sleepers show a distinct pattern of spontaneous brain rhythms.

During sleep, brain waves become slow and organized and the thalamus, a way station for all types of sensory information except smell, spontaneously engages with the cortex. This interaction can produce transient fluctuations of the brain's electric field visible on the EEG as rhythmic spindles - brief bursts of faster-frequency waves. 

Will picosatellites pollute space like in Wall-E? Why do we let amateurs kill Mother Earth? Send in the UN!

These are part of the overwhelming comments following my Discovery interview. I am amazed at the variety of space litter connondrums presented.  I thought about writing a calm, well-measured response, but you know what?  If the posters can rant, so can I!


Unlike them, however, I will rant with scientific backing on my side.
