Hard drives that combine a traditional spinning platter for mass storage and solid state flash memory for frequently accessed data, have always made sense. They may be slower than SSDs, but they are a lot cheaper gigabyte-for-gigabyte. CNET's Harry McCracken speculates on how soon such drives may become mainstream.

A study by Oregon State University suggests that the effects of rising levels of carbon dioxide on temperature may be less than previously thought.
The new models predict that given a doubling in CO2 levels from pre-industrial levels, the Earth's surface temperatures will rise by 1.7 to 2.6 degrees C. That is a much tighter range than suggested by the Intergovernmental Panel on Climate Change (IPCC)'s 2007 report, which suggested a rise of between 2 to 4.5 degrees C.

The Google.org-funded Enhanced Geothermal Systems (EGS) research at the Southern Methodist University has produced a coast-to-coast geothermal potential map of the United States. Having invested over $10 million on geothermal energy, Google seems to believe that it is our best bet at kicking the oil habit (especially now that nuclear power has suddenly become disproportionately unpopular).

From the NY Times: On May 26, 2009, Robert Lustig gave a lecture called “Sugar: The Bitter Truth,” which was posted on YouTube the following July. Since then, it has been viewed well over 800,000 times, gaining new viewers at a rate of about 50,000 per month, fairly remarkable numbers for a 90-minute discussion of the nuances of fructose biochemistry and human physiology.
