China and Russia have jointly conducted a controversial series of experiments to modify Earth’s atmosphere with high-frequency radio waves. From a Russian installation called the Sura Ionospheric Heating Facility near the town of Vasilsursk, east of Moscow, scientists emitted high-frequency radio waves to manipulate the ionosphere, while the China Seismo‐Electromagnetic Satellite (CSES) measured the effects

Like divorced parents during the festive season, physics is made of two beloved authorities who just can’t get on – general relativity and quantum mechanics. For decades, many researchers have pinned their hopes of unification on something called string theory. On the up side it points to a curious connection between gravity and the behaviour

Historically, tornadoes have been thought to originate in the clouds, reaching turbulent fingers down to Earth. But now a team of climatologists has demonstrated that this ‘top-down’ model of tornadogenesis might actually be wrong.   Yep. Tornadoes, their research has found, form from the ground up. Tornadoes can form surprisingly quickly, in just a couple

The largest diamond ever discovered in North America was unearthed in October, Canadian mining company Dominion Diamond Mines announced in a Thursday news release. Weighing in at 552 carats, the yellow diamond was recovered at the Diavik Diamond Mine, located in Northern Canada about 135 miles south of the Arctic Circle.    Bloomberg News reports that

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships. It’s a goal that sounds so fantastic, you’d be forgiven for dismissing it as science fiction. But it’s no joke, and the project’s chief engineer says millions of dollars’ worth of work is moving along without any

Shark populations off the east coast of Australia have been declining over the past 55 years with little sign of recovery, according to research published in the journal Communications Biology.   Coastal shark numbers are continuing a 50-year decline, contradicting popular theories of exploding shark populations, according to an analysis of Queensland Shark Control Program

Two fire technicians have died after a generator incident occurred at one of the largest stations in Antarctica. According to the National Science Foundation (NSF), on 12 December, the two technicians were performing routine maintenance on a generator building’s fire suppression system. The generator powers a radio transmitter nearby the station.   Unfortunately, the maintenance did

Scientists in Germany say they have hit a new superconductivity milestone. According to their paper, they achieved resistance-free electrical current at the highest temperature yet: just 250 Kelvin, or -23 degrees Celsius (-9.4 degrees Fahrenheit).   Although the team’s superconducting material has yet to be verified, the claim has merit – the work was led

How do fish breathe underwater? It’s the kind of question children ask. They get their oxygen in the water, we tell them – but sadly, that’s not always true. The world’s oceans are currently undergoing a dangerous transformation. Scientists have detected vast ‘dead zones’ around the world, where hypoxic water lacks the necessary oxygen for

Scattered among your genes like old recipes in an heirloom cookbook are DNA sequences that once helped Neanderthals survive. The codes that contributed to the construction of our extinct cousin’s ever-so-slightly elongated skulls could still be at work in some modern humans, affecting neurological development and pushing their craniums into a slightly different shape.
