Thermaltake Announces New Laptop Cooler
Thermaltake has announced a new option for users looking for laptop cooling, the Massive 14². The cooler gets its name from a pair of 140mm LED fans that provide all the cooling power. A fan speed controller is available to push the fan speed up to 1200RPM and an LED controller allows the user to modify their lighting options. An ergonomic design ensures that users can enjoy hours of comfortable use.

Finding How Electrons Pair in Magnetic Superconductors
Many technologies have changed the world the moment they are invented as they trivialize challenges. One technology yet to be invented that will have a similar impact is room temperature superconductors, which will allow electrical currents to flow with no loss. Researchers at Brookhaven National Laboratory, Cornell University and others have successfully observed something that could bring us closer to the day such superconductors are realized.
Conventional superconductors only become superconducting at extremely low temperatures when vibrations in their crystal lattices are able to couple electrons together, so they may flow without resistance. Unconventional superconductors, which can be superconducting at higher temperatures, rely on a different mechanism that may be related to the materials' magnetism. To test this, the researchers had to develop a microscopy technique capable of distinguishing energy levels orders of magnitude smaller than the energy of a single photon. They then placed CeCoIn5, an unconventional superconductor, into the microscope and shot bursts of energy at it to break apart the superconducting electron pairs on it. The electrons would fly off in different directions, striking impurities and forming an interference pattern, which can be used to determine if magnetism mediated the bonding between the electrons.
The researchers' unprecedented study has shown that indeed the material's magnetism does lead to the electron pairing. With this knowledge it should become possible to write the equations that describe the superconducting mechanism in this and other materials, and potentially lead to new materials with better properties.

AMD's Power House CPU Now Available in Stores
AMD announced a new powerhouse some time ago, the 8-core FX-9590, which is the world's first commercially available 5 GHz processor;
however, the processor, along with its little brother, the 8-core
FX-9370, was not available at that time. They are now though, as they
have been seen at TigerDirect, selling for $829 for the FX-9590 and $329
for the FX-9370. The FX-9370 is also available in iBUYPOWER's gaming
rigs, though at a slightly higher price of $353.34.
The
FX-9590 has a base clock frequency of 4.7 GHz and a max turbo frequency
of 5.0 GHz, while FX-9370 has a base clock frequency of 4.4 GHz and a
max turbo frequency of 4.7 GHz, and

Details on New Sapphire 7990 Atomic Card Leaked
Sapphire
wants to show off, it appears, with its new Radeon HD 7990 Atomic
graphics card. It was first unveiled at Computex, but the details were
scarce at the time. Now, however, there is more information on the
graphics card, and it seems that Sapphire has put all its knowledge into
designing this graphics card.
The
card use have two 28 nm Tahiti XT2 GPUs that will be hooked up to a
total of 6 GB of GDDR5 memory. The processors will be placed on a black,
custom 12-layer PCB that will house an impressive 18-phase VRM that
gets its power from three 8-pin PCI-Express connectors. Each of the two
processors will have its own 6+2+1 phase power supple for Vcc, VDDCI and
MVDD, along with two sets of BIOS' for each of the processors. The PCB
will also house six mini-DisplayPorts, which should be sufficient for
pretty much anyone. Sapphire claims that the card will be able to run a
CrossfireX configuration with any 7900 series card aswell.
The
cooling will be provided by a full-cover water block that is hooked up
to a 240 mm radiator, which is cooled by two 120 mm 1200 RPM fans, and a
reservoir+pump combo to get the water flowing.
There
are currently no details on clock speeds, pricing or a launch date, but
I will keep my eyes and ears open in case Sapphire announces anything
new about the Radeon HD 7990 Atomic.

Watching Lithium Ions Move
At their core, all batteries are the same as ions move between electrodes, storing energy in bonds. Of course the exact mechanics of this process differs between battery types, and to design the best batteries, one must understand those mechanics. This is not a simple task with lithium ion batteries though, as lithium atoms are so small, but researchers at Michigan Technological University have successfully observed those atoms within a battery.
Lithium is the third lightest element, so watching it move through a system requires a special tool; an aberration corrected scanning transmission electron microscope (AC-STEM). Using one at the University of Illinois at Chicago, the researchers watched lithium ions in a nano-battery enter a tin oxide electrode. Modern lithium-ion batteries use graphite for their electrodes, but different electrodes allow for faster charging and discharging, as well as greater energy storage. Tin oxide has potential as a replacement for graphite electrodes, but requires further study. In this study the researchers found that lithium ions enter the electrode via specific paths, and did not simply enter the electrode randomly.
Over time the motion of ions in to and out of electrodes stresses them to the point of failure, which is why this kind of research is critical. It allows for the amount of strain on the electrode to be calculated, which many other laboratories are interested in as well.
