New camera shows blood flow

A Swiss company has developed a camera which shows how blood is circulating through the skin in real-time.

The camera is designed to help assess the extent and severity of burns.

The device has been trialled by burn specialists and reconstructive surgeons at CHUV University Hospital in Lausanne, Switzerland.

Clinical data from the trial is being presented at the 14th European Burns Association Congress in the Hague on Wednesday.Read more

Emotion sensor catches out liars

United Kingdom – A sophisticated new camera system can detect lies just by watching our faces as we talk, experts say.

The computerised system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms.

Researchers say the system could be a powerful aid to security services.

It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University. Read more

Planet with double sunset found

WASHINGTON — The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA’s Kepler mission has made the first unambiguous detection of a circumbinary planet — a planet orbiting two stars — 200 light-years from Earth.

Unlike Star Wars’ Tatooine, the planet is cold, gaseous and not thought to harbor life, but its discovery demonstrates the diversity of planets in our galaxy. Previous research has hinted at the existence of circumbinary planets, but clear confirmation proved elusive. Kepler detected such a planet, known as Kepler-16b, by observing transits, where the brightness of a parent star dims from the planet crossing in front of it. Read more...

‘Microwave waste’ to get biofuel

Microwaving waste food products could be used to produce important chemicals and biofuels, new technology has shown.

The methods would potentially allow food waste to be processed at home and on an industrial scale.

The technology could provide a renewable source of carbon, as well as addressing the growing problem of global waste.

Professor James Clark of the University of York unveiled these plans at the British Science Festival in Bradford.




Using highly focused microwaves, the scientists believe they can input any organic waste, and extract useful chemical compounds that can be harnessed in materials and biofuel applications.

An international group of scientists have been working together to develop this technology, and they plan to build a demonstration facility in York later this year. Read more...

Dengue cases down this September, DOH

Manila – The DOH reported 70,204 dengue cases for week ending September 10, 2011. This was over 24,000 cases less or 25.87% lower than for the same period last year. In addition, the number of cases in July and August (the peak months for dengue) was 52% lower than last year. A total of 396 deaths were reported for this year, which is lower than last year’s number of 620. Read more...

The quest for an unhackable code

Every day the news hits of another company, website or long list of credit cards that's been hacked. But what if there was a foolproof technology to fend off cyberattackers by keeping secret information secret? Would an unhackable encryption algorithm do the trick? Read more...

Warning! Iranians hit in email hack attack

Up to 300,000 Iranians may have had their Google email monitored using security certificates stolen from Dutch firm DigiNotar. The figure came from a report into the breach at DigiNotar which let attackers generate hundreds of fake certificates. Read more

Risks of nanotechnology

Developing countries forging ahead with nanotechnology need regulation and research into local risk patterns, say Alok Dhawan and Vyom Sharma.

Nanotechnology, the science of manipulating tiny particles less than 100 nanometers in diameter, has found many applications in consumer products, biomedical devices, drug delivery agents and the industrial sector.
In the consumer sector alone, more than 30 countries are manufacturing some 1,300 nanotech-based products, including textiles, food packaging, cosmetics, luggage, children’s toys, floor cleaners and wound dressings. The number of such products has increased five-fold in the last five years. More
