One thing IBM emphasizes about its neurosynaptic chip is that it works like the “right” brain, which means intuition and jumping to conclusions, whereas the “left” brain works more like a traditional computer: R. Colin Johnson

In a paper published in Nature Communications researchers at IBM describe how they have built a silicon-based receiver chip incorporating GFETs or Graphene Field Effect Transistors (the purple structure in the photo) into the circuit. The multi-stage receiver integrated circuit consists of 3 graphene transistors, 4 inductors, 2 capacitors, and 2 resistors.
“This is the first time that someone has shown graphene devices and circuits to perform modern wireless communication functions comparable to silicon technology,”
said Supratik Guha, Director of Physical Sciences at IBM Research. In a test the team successfully used the graphene-based receiver to process a digital transmission on 4.3GHz. The binary sequence received was 01001001 01000010 01001101, which represents ASCII coding of the letters IBM.

IBM Research – Almaden physicist Andreas Heinrich explains the industry-wide need to examine the future of storage at the atomic scale and how he and his teammates started with 1 atom and a scanning tunneling microscope and eventually succeeded in storing one bit of magnetic information reliably in 12 atoms.

3M and IBM announced that the two companies plan to jointly develop the first adhesives that can be used to package semiconductors into densely stacked silicon “towers.” Processors could be tightly packed with memory and networking, for example, into a “brick” of silicon that would create a computer chip 1,000 times faster than today’s fastest microprocessor enabling more powerful smartphones, tablets, computers and gaming devices.

Using the Bus Pirate to read the SVP supervisor power on password off an IBM T30 Thinkpad: [via]
A friend of mine recently came upon an old IBM T30 Thinkpad at an auction for $40. Bringing it home, he found that there was a power-on supervisor password. This can’t be reset by removing the battery, as the pswd is stored on an EEPROM on the motherboard….. So it came to me!
I recently purchased a Bus Pirate v3 from Seeedstudio, and decided to give it a quick test run..

As detailed in this report, IBM has announced their first graphene integrated circuit. Graphene’s structure of one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice make it one of the thinnest semiconductor materials.
Further development using graphene should open the door to greater practicality of flexible electronics. While this technology is not expected to begin displacing conventional silicon circuits for a few years, when it does it should lead to bendable, transparent circuit boards revolutionizing the integration of embedded systems into common everyday items.
