BioCDS could hit No. 1 on doctors' charts
...r surface. These microscopic pits, which represent binary ones or zeroes depending on their size, are etched in concentric tracks circling the midpoint from the inner to the outer edge of a CD. "It is these pits which we transform into miniature test tubes," Nolte said. "Each pit can hold a trace quantity o...ASU advance could provide insight into human's ability to recognize patterns
...n contrast, digital computer memories operate on a binary number system (1 or 0). An important advance was made in this area in the 1980s by John Hopfield, a Caltech researcher at the time, who developed the "Hopfield network" to help understand how biological memory works. But the main drawback of the Hop...Story tips from the Department of Energys Oak Ridge National Laboratory, February 2004
...lar explosions happen when a white dwarf star in a binary system accretes material from its neighbor until, eventually, the big blast occurs. ORNL astrophysicists were among researchers who applied their computational and experimental support to work published in a paper by Arizona State University. The new...Rutgers geneticists redefine the nature of hybrid corn
...s of heritable information may well constitute the binary system of the genetic world. "We got something super much more than we anticipated. We had heterosis with a firm, verifiable genetic foundation."...UC Riverside graduate student wins best poster award at international conference
... The title of Figueroa's poster was 'Clustering binary fingerprint vectors with missing values for DNA array data analysis.' Other co-authors of the winning poster were James Borneman, assistant professor of plant pathology, and Tao Jiang, professor of computer science and engineering at UC Riverside. ...Diabetes therapies and liquid memory may develop from micro fluid research, Science researchers say
... device, the flow of the polymer liquid mimics the binary guts of a computer. "This is a quite new and rather unexpected design. Construction of fluidic memory devices using polymer liquids has not been suggested before," said Groisman. The team designed and redesigned channel layouts, always looking for pa...Sex and gender scientists explore a revolution in evolution

...ctures, suggesting a nearly simultaneous impact of binary asteroids or fragmented comets, he said. An example of a twin impact structure would be the Kara / Ust-Kara twin impact structure in Russia which is about 73 million years old.

...he technology could apply. Computers operate on a binary system they rely on having an on and an off state. Typically, thats done with non-biological components now, Stayton said. This indicates another, very nice way to do it. The diminutive size of the proteins and molecules involved could open avenu...DFG to launch 21 new priority programmes

Information processing, communication, mobility and transport are based on networking, and so is social and political action of persons and organisations. In the priority prog...New technique shows scalability of DNA computing
... Mathematical formulas are used to manipulate that binary code to arrive at an answer. DNA computing, on the other hand, depends on information represented as a pattern of molecules arranged on a strand of DNA. Certain enzymes are capable of reading that code, copying and manipulating it in predictable ways...Genes Found That Label Cell Proteins For Disposal
... five different cullins. "That means thereare many binary ubiquitin ligases," Xiong says. "And it raises the possibilitythat degradation of different proteins may each require a different ubiquitinligase."

Ras can be thought of as a binary signal switch cycling between ON and OFF states which are characterized in terms of a small molecule, a guanine nucleotide, bound to the protein. In the resting cell, Ras is tightly bound to guanosine diphosphate (GDP), which is exchanged...Researchers Identify A Protein Critical For T Cell Development And Activation
...imulation of the immune systeminvolves more than a binary on-off response.
