Johns Hopkins researchers are testing an infrared scanning system to detect melanoma (Imag...

Although melanoma is one of the less common types of skin cancer, it is responsible for the majority (around 75 percent) of skin cancer related deaths. Part of the problem is that current diagnoses rely on subjective clues such as size, shape and coloring of a mole. With the aim of providing an objective measurement as to whether a lesion may be malignant, researchers at John Hopkins University have developed a prototype non-invasive infrared scanning system that works by looking for the tiny temperature difference between healthy tissue and a growing tumor.  Read More

Dr Philip Rasch is Pacific Northwest National Laboratory's first Chief Scientist for Clima...

Scientists in the US have been cloud-spotting over shipping lanes and have noticed something more interesting than teddy-bear shapes and faces. They have detected that rising steam from passing ships has caused brightening in the clouds which they theorize alters the reflectivity of the cloud and prevents the energy from reaching the Earth. They propose that if this could be achieved artificially via geoengineering it could be an effective defense against global warming.  Read More

Skidmore, Owings and Merrill LLP intend to install a geothermal heat exchange system in a ...

Skidmore, Owings and Merrill LLP (SOM) has just unveiled details of the first phase for the expansion and redevelopment of three business districts in China's capital city, Beijing. Key to the success of the project is the installation of a Central Park area which will help to heat and cool energy efficient buildings in the Dawangjing District by geothermal exchange instead of relying on energy-intensive cooling towers.  Read More

The heat from the human body could be harvested to run low power electronic devices

Efforts to capture energy from the human body usually focus on harnessing the kinetic energy of the body’s movement. However the human body is also generating energy in the form of heat that could also be used to run low power electronic devices. New energy-scavenging systems under development at MIT could generate electricity just from differences in temperature between the body (or other warm object) and the surrounding air.  Read More

Panasonic's new LUMIX DMC-TS2

Panasonic has announced significant improvements in the toughness department with its new 14.1-megapixel LUMIX DMC-TS2. It's now waterproof to even greater depths, can survive being dropped from a height of six feet and winter sports enthusiasts will no doubt be pleased to hear that it can also withstand some seriously chilly temperatures.  Read More

Previous studies have indicated that painting the roofs of buildings white could be a low tech way to reduce global warming by reflecting the sun’s rays back into space. Now the first computer modeling study to simulate the impacts of white roofs on urban areas worldwide has added more weight to such a proposal indicating that painting every roof in a city entirely white could cool the world’s cities by an average of about 0.7 degrees Fahrenheit or 0.4 degrees Celsius.  Read More

The Moen ioDIGITAL controls water temperature, fill levels and can be controlled remotely ...

Currently, your iPod might have your favorite songs personalized the way you like them and your laptop might be customized with your own homepage material. But what about your shower or bath? Do they know what you like? An easy-to-use interface for your bathroom is now available from Moen that gives you the ability to set and maintain water temperature, levels and flow with electronic precision – even remotely. The ioDIGITAL is available for three Moen products: the vertical spa, shower and Roman tub.  Read More

Intelligent, radio-enabled blood bags could monitor blood temperature to avoid wastes and ...

During high-risk medical operations surgeons keep blood supplies at hand so that they are ready to face possible emergencies; but blood bags can only be reused if the cold chain has been maintained, meaning that a portion of such a precious and limited resource routinely goes wasted. To face this problem, researchers at the Fraunhofer Institute in Germany have proposed intelligent blood bags with an embedded a radio chip that constantly monitors temperature and checks for blood type compatibility with the patient, avoiding possible mistakes.  Read More

New research indicates a mini ice age can be brought on in a matter or months (Image: NASA...

Those who scoffed at the swiftness with which the world was plunged into an ice age in the film The Day After Tomorrow may need to rethink their disbelief with new research showing that such a scenario may not be so far from the truth. A new study reveals that switching off the North Atlantic circulation can force the Northern hemisphere into a mini ‘ice age’ in a matter of months rather than the tens of years indicated by previous research.  Read More

The 'Thermeleon' roof tile changes from white to black depending on its temperature

Prototype roof tiles that turn white to reflect heat when they get hot seem like a pretty cool idea, as do tiles that turn black to absorb heat when it’s cold. That’s why a team of Massachusetts Institute of Technology (MIT) graduates has won the third annual MIT MADMEC (Making and Designing Materials Engineering Contest) by demonstrating their thermally-activated, color-changing, roofing material called “Thermeleon” (as in chameleon).  Read More
