Australian fire beetle avoids the heat
The Australian jewel beetle Merimna atrata has several heat sensors. Originally, it was thought to use them to detect forest fires as it lays its eggs in the wood of burned eucalyptus trees. Researchers at the University ...
Innovative diode design uses ultrafast quantum tunneling to harvest infrared energy from the environment
Most sunlight striking the Earth is absorbed by its surfaces, oceans and atmosphere. As a result of this warming, infrared radiation is emitted constantly all around us-estimated to be millions of Gigawatts per second. A ...
Image: Saturn's north pole
Reflected sunlight is the source of the illumination for visible wavelength images such as the one above. However, at longer infrared wavelengths, direct thermal emission from objects dominates over reflected sunlight. This ...
High-resolution optical coherence tomography without particle accelerator
A visit to the optometrist often involves optical coherence tomography. This imaging process uses infrared radiation to penetrate the layers of the retina and examine it more closely in three dimensions without having to ...
VISTA peeks through the Small Magellanic Cloud's dusty veil
VISTA's infrared capabilities have now allowed astronomers to see the myriad of stars in the Small Magellanic Cloud galaxy much more clearly than ever before. The result is this record-breaking image—the biggest infrared ...
An LED-based device for imaging radiation induced skin damage
To eradicate any cancer cells that may potentially remain after surgery or chemotherapy, many breast cancer patients also undergo radiation therapy. All patients experience unfortunate side effects including skin irritation, ...
Polar balloon STO2 to go the edge of space with Dutch instruments
Stars and planets are born from clouds of molecules that coagulate and eventually fall apart again in the space between the stars in a galaxy. Astronomers still do not know exactly how this works.
The quantum sniffer dog
As humans, we sniff out different scents and aromas using chemical receptors in our noses. In technological gas detection, however, there are a whole host of other methods available. One such method is to use infrared lasers, ...
Engineers develop a plastic clothing material that cools the skin
Stanford engineers have developed a low-cost, plastic-based textile that, if woven into clothing, could cool your body far more efficiently than is possible with the natural or synthetic fabrics in clothes we wear today.
