    The Vaulter Disk is a flash memory based disk accelerator that operates in parallel with a PC’s hard disk, speeding up disc operations. Vaulter will arrive in capacities ranging from 8GB to 16GB and the PCI Express device will have versions for both laptops and desktops. Sandisk says that the new Vaulter Disk will be available to Original Equipment Manufacturers (OEMs) early in 2008.

  • Exactly what type of neutron star Calvera is remains a mystery. According to Dr Rutledge, there are no widely accepted alternative theories to explain objects such as this that are bright in X-rays and faint in visible light.  

     "Either Calvera is an unusual example of a known type of neutron star, or it is some new type of neutron star, the first of its kind," said Dr Rutledge. 

     Calvera's location high above the plane of our Milky Way galaxy is also a mystery. The researchers believe the object is the remnant of a star that lived in our galaxy's starry disc before exploding as a supernova.  

     In order to reach its current position, it had to wander some distance out of the disc.

  • Oceans are natural CO2 sinks, and represent the largest active carbon sink on Earth. This role as a sink for CO2 is driven by two processes, the solubility pump and the biological pump.[2] The former is primarily a function of differential CO2 solubility in seawater and the thermohaline circulation, while the latter is the sum of a series of biological processes that transport carbon (in organic and inorganic forms) from the surface euphotic zone to the ocean's interior. A small fraction of the organic carbon transported by the biological pump to the seafloor is buried in anoxic conditions under sediments and ultimately forms fossil fuels such as oil and natural gas.

  • Other things to consider: how much compression is possible? Can Kolmogorov simplicity radically help in the compression? How much processing power do you save by just simulating subjective experiences? Would only a small portion of the universe's timescale be simulated? And so on.

  • Brin writes,
    Let there be no mistake. METI is a very different thing than passively sifting for signals from the outer space. Carl Sagan, one of the greatest SETI supporters and a deep believer in the notion of altruistic alien civilizations, called such a move deeply unwise and immature....

  • This is the real problem with self-engineering. It seizes control of humanity so radically that humanity can no longer judge it. We can’t be certain it’s diminishing us. But we can’t be certain it’s perfecting us, either. Sandel got it half right, which ain’t bad. Nobody’s perfect.
