IBM scientists have created a one-step point-of-care-diagnostic test, based on an innovative silicon chip, that requires less sample volume, is significantly faster, portable, easy to use, and can test for many diseases, including one of world's leading causes of death, cardiovascular disease*. The results are so quick and accurate that a small sample of a patients serum or blood, could be tested immediately following a heart attack, to enable the doctor to quickly take a course of action to help the patient survive.
As reported in Lab on a Chip, December 2009, Volume 9, Issue 23, IBM Research - Zurich scientists Luc Gervais and Emmanuel Delamarche, in collaboration with the University Hospital of Basel in Switzerland, have developed a new diagnostic test that uses capillary forces to analyze tiny samples of serum, or blood, for the presence of disease markers, which are typically proteins that can be detected in peoples blood for diagnostic purposes. Capillary action force is the tendency of a liquid to rise in narrow tubes or to be drawn into small openings. An everyday example of a capillary action force can be viewed by dipping a paper towel in a cup of water - the microstructures in the paper fiber enable the towel to absorb the water.

Grady Booch is recognized internationally for his innovative work in software architecture, software engineering, and collaborative development environments. He has devoted his life's work to improving the art and the science of software development. Grady served as IBM's Chief Scientist of Rational Software Corporation since its founding in 1981 and through its acquisition by IBM in 2003.
He now is part of the IBM Thomas J. Watson Research Center serving as Chief Scientist for Software Engineering, where he continues his work on the Handbook of Software Architecture and also leads several projects in software engineering that are beyond the constraints of immediate product horizons. Grady continues to engage with customers working on real problems and is working to build deep relationships with academia and other research organizations around the world. Grady is one of the original authors of the Unified Modeling Language (UML) and was also one of the original developers of several of Rational's products. Grady has served as architect and architectural mentor for numerous complex software-intensive systems around the world in just about every domain imaginable.

A team of IBM Researchers is exploring new and innovative ways to quickly read human DNA at a low cost -- an advancement that can lead to important breakthroughs in health condition diagnosis and treatment.
The scientists are designing a "DNA Transistor" which is created by using an electron beam to make a nanometer-sized opening in a microchip, called a nanopore, to read DNA Molecules.
A DNA molecule consists of millions of different nucleotides that make up the human genome; the blueprint of living organisms.
Next, single strands of DNA molecules that are floating above the microchip are threaded or pulled through the nanopore by an electrical field, which begins the process of reading and sequencing the molecules.
The DNA Transistor device consists of alternating nanometer-sized layers of metal and dielectric. Discrete charges located along the backbone of a DNA molecule get trapped by electrical fields inside the nanopore. By trapping the DNA molecule, scientists will have ample time to measure the molecule structure.
By cyclically turning on and off these gate voltages, researchers have shown theoretically and computationally, and expect to be able prove experimentally, the plausibility of moving DNA through the nanopore at a rate of one nucleotide per cycle a rate that IBM scientists believe would make DNA readable.
Low-cost, yet efficient analysis of DNA data promises to help facilitate the discovery of new healthcare products, and help determine an individual's predisposition to a particular disease or condition.

On September 28, 1989, Don Eigler became the first person in history to move and control an individual atom. Shortly thereafter, with the help of a custom-built microscope, he and his team spelled out the letters I-B-M using individual atoms, signaling a quantum leap forward in the field of nanotechnology.
Eigler built his scanning tunneling microscope (STM) in order to visualize and experiment with individual molecules and atoms. As he experimented, he discovered that it was possible to pick up individual atoms and move them using the tip of his STM. To demonstrate this ability, he created the worlds tiniest IBM logo, made out of 35 Xenon atoms.
Because of Dr. Eiglers seminal work, scientists continue making breakthroughs that continue driving the field of nanotechnology, the exploration of building structures and devices out of ultra-tiny components as small as a few atoms or molecules. Such devices might be used as future computer chips, storage devices, biosensors, and things nobody has even imagined.

As reported in the August 28 issue of Science magazine, IBM Research Zurich scientists Leo Gross, Fabian Mohn, Nikolaj Moll and Gerhard Meyer, in collaboration with Peter Liljeroth of Utrecht University, used an AFM operated in an ultrahigh vacuum and at very low temperatures ( 268oC or 451oF) to image the chemical structure of individual pentacene molecules. With their AFM, the IBM scientists, for the first time ever, were able to look through the electron cloud and see the atomic backbone of an individual molecule. While not a direct technological comparison, this is reminiscent of X-rays that pass through soft tissue to enable clear images of bones.
