Currently, if you want to measure someone's blood oxygen levels, you have to use an oximeter that clips onto their finger. An experimental new system, however, is able to check those levels anywhere on the body – and that could mean big things for the field of medicine.

When it comes to cooking in your oven, you simply set the temperature to the exact number required. For stove-top cooking, though, you have to estimate if the saucepan is at more or less the right temperature. PanPerfect offers a way of knowing exactly how hot it is.

Scientists may have discovered large amounts of water hidden deep beneath the surface of Jupiter’s famous Great Red Spot. The discovery, which was made using ground-based telescopes, opens up the possibility that extremophile lifeforms could exist in the atmosphere of the enigmatic gas giant.

Saturn’s moon Titan is one of the most interesting bodies in the solar system – but at a glance it looks like a dull yellow ball, thanks to a soupy atmosphere. Now, using 13 years’ worth of infrared data from Cassini, astronomers have stitched together the clearest images yet of Titan’s surface.

A company called Brava is launching a countertop oven that cooks food quickly and thoroughly using visible and infrared light, and if you cut through the marketing faff it looks like there might just be a useful product hiding under there.

In the movie "Predator," Arnold Schwarzenegger hid from an alien's night vision system by covering himself in mud. He might have found things much easier, however, if he'd had access to a newly-developed thermal camouflage material.

Metamaterials that cloak people and objects from radar, visible light or infrared are usually thick and heavy, but now engineers at the University of Wisconsin-Madison have developed an ultrathin, lightweight sheet that absorbs heat signatures and can even present false ones.

While landmines in general are pretty awful, the PFM-1 "butterfly" mine is particularly nasty. Because of its mainly plastic construction, the butterfly-shaped device is notoriously difficult to find using metal detectors. Now, however, it turns out that drones can be used to locate the things.
