Temperature

Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient.

Earth saw its hottest day on record this week – twice. According to the Copernicus Climate Change Service data, Sunday claimed the top spot for highest global average temperature since the records began in 1940, only to be broken again on Monday.

There are already a number of experimental prosthetic hands that provide users with the tactile sensation of touching an object. The MiniTouch system takes things further, as it allows users to sense the temperature of items that they're touching.

If you want to continuously monitor your body temperature, and you already wear earrings all day long, why not just have those earrings do the job? That's the thinking behind the Thermal Earring, which may someday be coming to an ear near you.

People suffering from major depressive disorder (MDD) are also more likely to have higher body temperatures, finds the largest study of its kind – and surprisingly, one suggested treatment is to heat the body up even more, with saunas and hot yoga.

Trees such as maples have "fruits" known as samaras, which consist of a seed joined to a papery wing. Scientists have now created artificial samaras, which could be used to quickly and easily monitor soil temperature from the air.

It’s a basic fact that temperatures drop at night, damaging crops, equipment and infrastructure. Scientists have created a new film that selectively absorbs and reflects different wavelengths of infrared light to efficiently keep objects warm.

Scientists have demonstrated a new ultra-white ceramic material that drastically cools buildings, with record-high sunlight and heat reflectivity. The beetle-inspired material gets its ability from its nanostructure and should be easy to mass produce.

With a continuing hot streak felt across the Earth, 2023 is now on track to be the warmest year on record. And September was no exception; in fact, it broke existing records by a large margin, according to the World Meteorological Organization.

NASA and NOAA have confirmed that July 2023 was the hottest month in recorded history, which goes back about a century and a half. The finding follows a worrying trend that has a decent chance of setting 2023 as the hottest year on record.

As global temperatures soar, the ability to adapt is vital for every species, including our own. Scientists are hoping that by putting one more sweaty body out on the street, we'll find new ways to combat potentially deadly heat-related health risks.

Large fluctuations in outdoor temperatures can shorten the lifespan of the batteries used in electric cars – if those cars are parked outside, that is. An experimental new car-cloak could help minimize such damage, by damping changes in temperature.
