Boffins don't want to burst your bubble – they create them with sound

Video Fluid dynamics is weird. Physicists have reverse engineered the popping of a bubble and managed to keep it levitated just by using the power of sound. Iridescent bubbles form when a film of soapy liquid is punctured. The film retracts from the hole and the molecules are pulled back and rearranged to reduce its surface area, …

Drama as boffins claim to reach the Holy Grail of superconductivity

A pair of physicists have claimed to reach the holy grail in physics: room temperature superconductivity. Unsurprisingly, the results have raised several eyebrows and the fear of another cold fusion fiasco. It has also led to a series of strange events involving the impersonation of a famous physicist using an encrypted email …

Now that's a dodgy Giza: Eggheads claim Great Pyramid can focus electromagnetic waves

The Great Pyramid of Giza, the oldest of the Seven Wonders of the Ancient World, has remained an architectural mystery. How was it built? Why are its dimensions so perfect? And, er, can it concentrate electromagnetic energy? Yes, it can, allegedly, according to a paper published in the Journal of Applied Physics. "Egyptian …

Four hydrogen + eight caesium clocks = one almost-proven Einstein theory

A team at the National Institute of Science and Technology (NIST) has used a range of atomic clocks from around the globe to test the equivalence principle* of Einstein's theory of general relativity. The research, published in Nature Physics, follows Einstein's thought experiment whereby the occupant of a windowless lift (or …

Boffins quietly cheering possible discovery of new fundamental particle: Sterile neutrino

It needs more sigmas, but Fermilab boffins in America are carefully speculating that they may have seen evidence of a new fundamental particle: the sterile neutrino. The suggestion follows tests conducted by the MiniBooNE (Mini Booster Neutrino Experiment) instrument, located near Chicago. Its mission is to detect neutrino …

Where to find dark matter? $34m says go look 2km under Canada

By the 2020s, boffins hope, a hockey-puck-shaped silicon and germanium crystal 2,000 metres below Canada will show a brief, tiny vibration, meaning a dark matter particle has collided with it. Dark matter has a big problem: scientists can detect its effects on the macro scale, but have never successfully detected any of the …

James Webb Space Telescope + luck = long distance astrofun

Researchers hope that NASA's budgetary-challenged James Webb Space Telescope (JWST) may score some good fortune with a boost from galactic alignment. While European Space Agency (ESA) scientists are breathless with excitement at the volume of star survey data received from the Gaia satellite, NASA researchers are comforting …

Fermi famously asked: 'Where is everybody?' Probably dead, says renewed Drake equation

If we ever detect signals from extraterrestrial civilisations, they are likely already dead, a somewhat downbeat update to the venerable Drake equation suggests. The original equation was devised in 1961 by astrophysicist Dr Frank Drake ahead of a meeting at the National Radio Astronomy Observatory in Green Bank, West Virginia …

For all we know, aliens could be as careless with space junk as us

A physicist at the Instituto de Astrofisica de Canarias in the Canary Islands has proposed a way by which planet hunters might detect advanced alien technology. Simply look for their junk in orbit. Thousands of exoplanets have been discovered in recent years, and huge observatories such as NASA's James Webb Space Telescope ( …

Soz, guys. No 'alien megastructure' around Tabby's Star, only cosmic dustbunnies

Sorry to burst your bubble, folks, but the mysteriously dimming Tabby's Star isn't due to an "alien megastructure" after all – it's just obscured by dust, according to a paper published today. KIC 8462852 (but Tabby's Star is catchier) was first spotted by NASA's Kepler telescope. It quickly became an object of fascination for …

Which distant Mars-alikes could we live on? Ask these Red Planet data-sifters

Scientists are applying knowledge gained from studying Mars to calculate how the atmospheres of theoretical exoplanets would behave. David Brain, professor at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder and co-investigator for NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) …

Sorry 'strange physics' fans, IceCube finds the Standard Model stands

Video Thanks to work at the IceCube instrument in Antarctica, we have learned that Earth has an appetite for high-energy neutrinos: they're more likely to be “swallowed” by the planet in collisions with matter than those at lower energies. The bad news: sorry about “new physics” expectations. The result is in line with the boring …

Hotter than the Sun: JET – Earth’s biggest fusion reactor, in Culham

Geek's Guide to Britain I’m in a room that, in normal circumstances, is not fit for human habitation. It features a number of big red buttons surrounded by illuminated yellow rings – just in case. “Push button to switch off Jet. Press only in case of extreme emergency,” the signs read, informatively. This is the Torus Hall, a 40,000m3 space the size …

Two hot Jupiters around two similar stars orbiting at similar distances look similar, right? WRONG

WASP-67 b and HAT-P-38 b are two far-flung exoplanets orbiting near-identical stars at similar distances. Their size and temperatures are also pretty close. So, naturally, astronomers thought that their atmospheres wouldn't be too far apart. They were wrong. "We don't see what we're expecting," said Giovanni Bruno, a …

Boffins have figured out a way of speeding up X-ray data collection

Researchers have developed a method to improve the characterisation of superfast X-rays that they say will allow data to be collected up to a thousand times faster. Physicists, biologists and chemists use X-ray pulses created by free-electron lasers, known as XFELs, to probe the structures and interactions of molecules. …

Scientists are counting atoms to figure out when Mars last had volcanoes

Astroboffins have figured out a new way of dating planets and meteorites by counting individual atoms in rock samples snatched from the depths of space. The atomic-scale imaging technique developed by University of Portsmouth scientists involves locating and counting individual atoms in planetary materials. "Directly linking …

Large Hadron Collider turns up five new particles

Boffins poring over data from the Large Hadron Collider's “Beauty” experiment are blinking in surprise, having turned up five new particles in one hit. The “hiding in plain sight” articles in data from the "LHCb" are all excited states of the baryon Omega-c-zero, Ωc0, and the CERN boffins saw the five new particles from its …

Time crystals really do exist, say physicists*

A new quantum state of matter has been experimentally observed for the first time, according to two papers published in Nature. In 2012, Frank Wilczek, a Nobel-prize winning physicist proposed the idea of "time crystals": an open, ground state system that breaks time translational symmetry. The name is a little confusing as …
