Information security experts believe the blurring of the boundaries between computer and biological viruses is not too far-fetched—and could have very real consequences. The origins of each virus are strikingly different: A computer virus is designed, whereas a biological virus evolves under pressure from natural selection. But what would happen if these origins are switched?…
The electric snail is here. There’s an electric cockroach too. Both are early experimental forays in a new line of research aimed at creating tiny, self-powered animal/machine hybrids as an alternative to tiny robots. Instead of starting from scratch and having to solve all those pesky movement problems that plague roboticists, some researchers have asked,…
The future of personalized genomic medicine can be glimpsed in a paper that reports the integration of lead author Michael Snyder’s genomic sequence with other ‘omics’ to give a read-out on his predisposition to disease, and his body’s response to viral infections and the onset of type 2 diabetes. As a proof-of-principle example of personalized…
A litany of food scares–and rules for organic produce–have pushed the industry to seek new solutions for food safety.
Humankind is constantly inventing new ways to stay in touch. But in some situations it’s difficult to keep the lines of communication open. A space shuttle’s radio falls silent when the craft slips behind a neighboring planet. A submarine loses contact when deep water blocks signals from the surface. Scientists recently proved possible a new…
Humans have always made inferences about causes and effects, sometimes based on scanty information. Many machines do now, too, and Judea Pearl is frequently cited as a cause.The computer scientist was named the latest recipient of the high-prestige Turing Award, which is awarded annually by the Association of Computing Machinery. It comes with a $250,000…
A prototype “space fence” designed to track Earth’s burgeoning orbital debris population passed a key test recently, locking onto objects in a demonstration run. The radar system, which is being developed by aerospace firm Lockheed Martin for the United States Air Force, has successfully detected orbiting space junk, company officials announced. The Air Force is…
Use your brain to control the world. That’s the promise of the brain-machine interface, a system that directly translates your thoughts into actions. At the South by Southwest Interactive conference, Julian Bleecker and Nicolas Nova, technologists from the Near Future Laboratory, have showed how popular culture has explored the possibilities of the devices—for both good…
In Silicon Valley, the line between computing and biology has begun to blur in a way that could have enormous consequences for human longevity. The promise is that low-cost gene sequencing will lead to a new era of personalized medicine, yielding new approaches for treating cancers and other serious diseases. The arrival of such cures…
More scientists are getting closer in the search for the “God particle” of physics that would help explain the fundamentals of the universe, but they haven’t found it yet. In the hunt for the Higgs boson, which is key to understanding why matter has mass, two teams of physicists using results from a now-closed American…
