Precise temperature measurements with invisible light

Ordinarily, you won't encounter a radiation thermometer until somebody puts one in your ear at the doctor's office or you point one at your forehead when you're feeling feverish. But more sophisticated and highly calibrated, ...

How hot is Schrodinger's coffee?

A new uncertainty relation, linking the precision with which temperature can be measured and quantum mechanics, has been discovered at the University of Exeter.

Monoterpene measures how certain forests respond to heat stress

In the tropics, forests consume large amounts of carbon dioxide through photosynthesis. Elevated temperatures suppress carbon dioxide absorption while promoting plants to emit the chemical monoterpene. Scientists found that ...

Video: How do we measure temperature?

We have a lot of confidence that we measure temperature accurately. But how do thermometers in the kitchen or doctor's office work? Thanks to the laws of thermodynamics, thermometers respond to heat moving from hot to cold ...

How researchers teach bacteria new behaviours

Researchers working in the field of synthetic biology use components that occur in nature and combine them in a new way. This is how bacteria acquire functions that they hadn't previously possessed. This offers great potential ...

The most accurate quantum thermometer

Scientists have defined the smallest, most accurate thermometer allowed by the laws of physics—one that could detect the smallest fluctuations in microscopic regions, such as the variations within a biological cell.
