Kirigami steers solar panels

by David, 15 December 2015 | 1 comments

When you’re installing solar panels, it’s important to point them at the Sun. But the Sun isn’t always in the same place – it moves across the sky over the course of a day. If you can aim the panels towards the Sun as it moves, they can produce up to 40 per cent more power…

Researchers have made sticky hand pads that let you climb walls like Spiderman. Inspired by gecko feet, a research lab at Stanford University in America developed the climbing device, which recently allowed a person who weighed 70 kilograms to climb a sheer glass wall. The team have also used the structure of gecko feet to…

Crystal clocks and atomic ticks

by , 29 August 2014 | 0 comments

One of our readers requested an article about time keeping devices, and it’s a great time for the topic. Scientists set a new record in clock precision early this year with an atomic clock that ‘ticks’ 430 trillion times in a single second. Most wristwatches and wall clocks today use a quartz crystal to keep…

Nuclear fusion offers to do just that, and scientists are looking for ways to harness this energy with experiments that run hotter than the Sun. The Sun is heated by fusion – a process where the nuclei of two small atoms, such as hydrogen,…

A whispering gallery of light has made the world’s most sensitive thermometer yet. This thermometer sets a new record in precision. Made by an Australian team of researchers, it is three times better than the previous record holder, and can measure temperature differences of just 30 billionths of a degree. This is the smallest change…
