Researchers at Stanford University are using computers and genomic information to predict new uses for existing medicines by analyzing genomic and drug data.

The scientists drew their data from the NIH National Center for Biotechnology Information Gene Expression Omnibus, a publicly available database that contains the results of thousands of genomic studies on a wide range of topics, submitted by researchers across the globe.… read more

Computational limits of spacetime

April 3, 2001

Forget Moore’s Law. Forget quantum computing. The real limits to computational growth may be the “foaminess” (noise) of spacetime itself at the level of 10-35 meters, says Jack Ng of the University of North Carolina, as reported in Physics News 532, March 28, 2001.

“The foaminess of spacetime leads to an uncertainty in timekeeping (the more accurate the clock, the shorter its lifetime), which in turn… read more

Computational feat speeds finding of genes to milliseconds instead of years

March 16, 2010

Computational analysis of existing data bases can dramatically shorten the time required to discover the specific combination of new genes involved in certain biological processes, Stanford University researchers have found.

The analytic methods can provide clues about where researchers should look next, such as finding new genes that play a role in developing cancers.

Subtle markers of heart damage hidden in plain sight among hours of EKG recordings could help doctors identify which heart attack patients are at high risk of dying soon, researchers from the University of Michigan, MIT, Harvard Medical School, and Brigham and Women’s Hospital in Boston have discovered,

The findings could help match tens of thousands of cardiac patients with life-saving treatment in time. Approximately… read more

Compression algorithms harnessed to fight HIV

February 25, 2005

Microsoft algorithms used to compress digital images and recognize patterns in email spam are being used to help scientists identify key genetic features across many different strains of HIV.

This could enable them to engineer an HIV vaccine that is effective against several strains at once.

Comprehensive model is first to map protein folding at atomic level

November 12, 2006

Scientists at Harvard University have developed a computer model that can fully map and predict protein folding for some 10 microseconds — about as long as some proteins take to assume their biologically stable configuration, and at least a thousand times longer than previous methods.

“This appears to have achieved a holy grail: simulating and predicting protein folding from a linear amino acid sequence,” said Ray Kurzweil. “It is… read more

Compounds that stimulate stem cell growth in the brain identified

September 1, 2006

Harvard University scientists have identified key compounds that stimulate stem cell growth in the brain, which may one day lead to restored function for people affected by Parkinson’s disease, strokes, multiple sclerosis, and a wide range of neurological disorders.

The research study focused on two compounds–LTB4 and LXA4. Both play a role in inflammation and are regulators of proliferation of several cell types. When stem cells isolated from the… read more

Compound blocks neurodegeneration in mice

October 30, 2013

neurodegeneration

An orally administered compound that prevents neurodegeneration in mice has been developed by researchers at the Medical Research Council (MRC) Toxicology Unit at the University of Leicester.

The team had found previously (Nature) that the build up of misfolded proteins in the brains of mice with prion disease over-activates a natural defense mechanism in cells, which switches off the production of new proteins.… read more

Complexity science: next big thing

September 4, 2001

The next big thing will be complexity science, the study of how order inevitability emerges from chaos, says Internet pioneer Jim Rutt. Rutt is interested in applying the theories of complexity science to develop computers, systems and software that will independently think and learn.

“When Ray Kurzweil wrote ‘Spiritual Age of Machines,’ I thought he was nuts,” Rutt said. “But now, I’m convinced that he is definitely onto something.… read more

Complex wiring of the nervous system may rely on a just a handful of genes and proteins

February 12, 2012

nervescontrolbody

Salk Institute researchers have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes.

The findings may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

The Salk researchers discovered that only a few proteins on the leading edge of… read more

Complex organic molecules discovered in infant star system

Hints that prebiotic organic chemistry is universal
April 7, 2015

Artist impression of the protoplanetary disk surrounding the young star MWC 480. ALMA has detected the complex organic molecule methyl cyanide in the outer reaches of the disk in the region where comets are believed to form. This is another indication that complex organic chemistry, and potentially the conditions necessary for life, is universal. (Credit: B. Saxton (NRAO/AUI/NSF))

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star, suggesting once again that the conditions that spawned our Earth and Sun are not unique in the universe.

This discovery, made with the Atacama Large Millimeter/submillimeter Array (ALMA), reveals that the protoplanetary disk surrounding the million-year-old star MWC 480… read more

Complex interactions may matter most for longevity, not single factors

May 16, 2014

Rand1_0

A new study of the biology of aging by Brown University biologists shows that complex interactions among diet, mitochondrial DNA, and nuclear DNA appear to influence lifespan at least as much as single factors alone. The findings may help scientists better understand the underlying mechanisms of aging and explain why studies of single factors sometimes produce contradictory results.

“I think the main lesson is that these interaction… read more

Complex Integrated Circuits Made of Carbon Nanotubes

December 17, 2009

The first three-dimensional carbon nanotube circuits, made by researchers at Stanford University, could be an important step in making nanotube computers in the coming decade that could be faster and use less power than today’s silicon chips.

The Stanford nanotube arrays are some of the densest ever made, with five to 10 nanotubes per micrometer, and the design makes it possible to create more complex nanotube circuits. But 100… read more

A simple sensor circuit made of hard-to-handle but promising carbon nanotubes is a first step in making the materials practical for computing, MIT Technology Review reports.

Transistors made from these nanomaterials are faster and more energy efficient than silicon ones, and computer models predict that carbon nanotube processors could be ten times less power-hungry. But it’s proved difficult to turn individual transistors into complex working circuits.… read more
