A newfound ability to model the complex feedback loops that control plant clocks could have important implications for computing One of the limitations of conventional thinking in computation is that computable functions proceed in a sequential manner, one independent step after another. When computer scientists talk of parallelism, they usually mean carrying out more than one of these independent...
In a pilot project, technology reduced doctor's visits for patients with chronic illness, but will this work on a broader scale? Connecting patients and their physicians through the internet might help cut down on office visits, according to results of a pilot project announced today. More than 250 patients with chronic diseases, namely diabetes, heart failure, and hypertension,...

The company showed off its behemoth instrument at aconference in Florida this week. Pacific Biosciences' highly-anticipated new sequencing machine has finally arrived.
Cleantech entrepreneurs urge Washington to make better use of Bay Area intellectual capital. At an event in downtown San Francisco on Tuesday, a representative of the Obama administration went before a gathering of Silicon Valley cleantech entrepreneurs to spread the good news about what's resulted from the stimulus package, and to get their feedback....
Can humans distinguish between sequences of real and randomly generated financial? Scientist have developed a financial Turing test to find out

One way to steal data is to embed it in a voice call over the internet. Now network engineers are learning how to spot such attacks ISo-called Voice of Internet Protocol or VoIP makes for cheaper and more convenient calling but it also opens an important issue of security. Various people have described how it might be possible to to hi-jack VoIP signals to send confidential information....

The mathematics that describe both sensory perception and the transmission of information turn out to have remarkable similarities In 1834, the German physiologist Ernst Weber (pictured above) carried out a series of experiments to determine the limits of sensory perception. He gave a blindfolded man a mass to hold and gradually increased its weight, asking the subject to indicate when he first...

Loan guarantees will help finance 400 megawatts of solar power. The Department of Energy (DOE)
A new mathematical model shows how the changing web of links between mobile phones could one day form an autonomous network One of the features of cellphone networks is that the nodes that distribute information are stationary, even though the phones themselves are not. These kinds of networks have been widely studied and do a good job of distributing voice and data in areas where the...
MIT economists probe the influence schools have on girls' math performance A few years ago, economics professor Glenn Ellison, PhD '92, started coaching the math team at his daughters' middle school near Boston. The all-girls squad consisted of his oldest daughter and her friends, and they made a run to the state finals. But Ellison noticed something striking. "We would go to math...
Researchers perform spying and other tricks. Though malware is not yet common on mobile phones, experts are taking a hard look at how it could appear down the road, hoping to find solutions before real attacks emerge.

A new mathematical model of hurricane formation finally solves one of the outstanding puzzles of climate change but also predicts dramatic increases in the number of storms as the world warms What factors determine how hurricanes form? Meteorologists have long known that two factors play crucial roles. First, the temperature of the sea determines the updraft of air that leads to a storm. Second,...

What could that mean for attempts to grow solar manufacturing in the United States? Because of its generous incentives program, Germany, a country that gets about as much sun as the darkest parts of the United States, has become the largest market for solar power in the world. That in turn has helped create a thriving solar manufacturing industry in the country. Because of its success, the...

Distinguishing quantum behaviour from its classical counterpart is harder than it sounds. Now a group of theorists have worked out how a few simple measurements can do the trick Imagine you want to measure the quantum behaviour of electrons in some kind of nanostructure, a quantum wire, say....

The PageRank algorithm behind Google's success was developed in 1998. But a project to trace the history of ranking algorithms has revealed an example developed in the 1940s The PageRank algorithm is a key part of Google's method of ranking web pages in search results. It uses the network of links between web pages to determine their value and, famously, judges a page to be important...

Small spinning asteroids are piles of rubble and dust that ought to fly apart but don't. Now astronomers have worked out why not What holds small asteroids together? Surely not gravity, they're too small for that. Today, Daniel Scheeres and buddies at the University of Colorado enlighten us with a study of the forces at work in these small bodies....

The Austrian physicist Victor Hess received the Nobel Prize for the discovery cosmic rays but a new translation of the work of an obscure Italian scientist indicates that he wasn't alone in this discovery. The history of science is littered with injustices and today Alessandro De Angelis at the University of Udine in Italy outlines another associated with the discovery of cosmic rays ....
The technologies presented spanned the ridiculous and the sublime. Yesterday, the second day of TED10, again offered attendees a bewildering but enriching intellectual diet. The technologies presented, especially, spanned the ridiculous and the sublime.
