‘Critical Slowing’ Warns of Looming Disasters
Scientists are homing in on a warning signal that arises in complex systems like ecological food webs, the brain and the Earth’s climate. Could it help prevent future catastrophes?
Halloween Skies to Include Dead Comet Flyby
The large space rock that will zip past Earth this Halloween is most likely a dead comet that, fittingly, bears an eerie resemblance to a skull. Scientists observing asteroid 2015 TB145 with NASA's Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii,
Canadian scientist thrills the web by live-tweeting spider sex
The detailed play-by-play of a black widow mating session in Toronto makes spiders seem more sweet than spooky. Catherine Scott studies courtship behaviour and sexual communication in black widow spiders, with a special interest in how pheromones on spide
Star Wars style sonic tractor beam invented by scientists
Darth Vader’s Death Star and Captain Kirk’s Starship Enterprise both had one. Now the tractor beam, that science fiction favourite deployed to memorable effect in numerous films and television series over the years, has finally arrived on Earth. A team of
'Zeno effect' verified: Atoms won't move while you watch
One of the oddest predictions of quantum theory ï¿½ that a system canï¿½t change while youï¿½re watching it ï¿½ has been confirmed in an experiment by Cornell physicists. Their work opens the door to a fundamentally new method to control and manipulate th
The bizarre reactor that might save nuclear fusion
If you’ve heard of fusion energy, you’ve probably heard of tokamaks. These doughnut-shaped devices are meant to cage ionized gases called plasmas in magnetic fields while heating them to the outlandish temperatures needed for hydrogen nuclei to fuse. Toka
New Galapagos giant tortoise species identified
Scientists have identified a new species of giant tortoise on the Galapagos Islands, using genetic data to determine that a group of 250 of the slow-moving grazing reptiles was distinct from other tortoise species residing in the Pacific archipelago.
Hidden no more
IN THE 1930s Albert Einstein was greatly troubled by a phenomenon that came from quantum theory. Entanglement, as it is called, forever intertwines the fates of objects such as subatomic particles, regardless of their separation.
Whisky returns after three years in space
Remember when Ardbeg Distillery sent a vial of unmatured malt whisky into space? Well the space Scotch has returned! And it has allegedly been changed by its time in microgravity.
Lack of science and maths skills 'can hamper adults'
Adults who lack basic science and maths skills risk being "bamboozled" and making bad decisions, according to a leading scientist. Teaching maths and science to all up to 18 would "produce a wiser population", says new British Science Association presiden
