Sensor promises disease detection with naked eye

British scientists have come up with a super-sensitive prototype sensor that lets doctors detect early stage diseases with the naked eye, an innovation that could prove valuable in countries that lack the resources for expensive diagnostic equipment.

The sensor, created at Imperial College London, relies on nanotechnology to analyze serum derived from blood samples.

A positive reaction to p24, a protein that indicates early HIV infection, or PSA, a protein that at certain levels can indicate prostate cancer, generates irregular clumps of nanoparticles that emit a blue color in a solution kept in a disposable container.

A negative reaction, however, … Read more

A bicycle built for two: One person, one skeleton

We at CNET of course believe in the importance of science education -- and if going on a 1,000-mile bike ride with a life-size skeleton as a passenger helps more students get one, why, all the better.

Kadhim Shubber, a physics undergraduate at the high-ranking science-based Imperial College London, is currently riding the length of the British Isles to raise money for his school's Rector's Scholarship Fund. It's a long and sometimes tedious journey, but Shubber has constant company in the form of King Arthur, an artificial skeleton riding on the back of his Claud Butler racing tandem. … Read more

The 404 1,077: Where we scrape the Surface (podcast)

The mystery of the magic Microsoft device is finally solved, but what's with all the unanswered questions? In trying to add fuel to the Surface hype machine, Microsoft leaves too much to the industry's collective imagination as we all keep speculating about the tablets' battery life, release dates, prices, and UI experience.

The competition among tablets is still presently in favor of the iPad, so we're hoping that Microsoft has more compelling announcements in the future that integrate some of the company's other inventions.

Jeff and I always fight about which popular musician deserves credit for this generation's aural decay, but the Imperial College in London may have a solution to our problem: let computers compose the music!

A team of researchers believe that digital music can move beyond human creation and evolve autonomously without a real composer. They've developed a learning computer algorithm that continuously creates and combines loops in a random sequence.… Read more

Guilt-free plastic for composting in your yard

A new sugar-based polymer could be used to make common food containers compostable at home right alongside your potato peels and egg shells.

A team of engineers and scientists at the Imperial College London led by Charlotte Williams in partnership with BioCeramic Therapeutics have created a degradable material from sugars derived from the breakdown of lignocellulosic biomass.

Williams noted in the group's announcement that while they're not the first to come up with a "biorenewable plastic," many of those have previously been made from sugar beet- or corn-based biomass.

It's a fairly accurate estimate.

In … Read more
