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

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

Medical magnetic resonance imaging, high-power microwave generators, superconducting magnetic energy storage units, and the solenoids in nuclear fusion reactors are very different technologies which all critically rely on the ability of superconducting materials to carry and store large electric currents in a compact space without overheating or dissipating large amounts of energy. Despite their extraordinary

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

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.

A drought scorched the Great Plains, causing wildfires and US$2.5 billion in agriculture losses. Catastrophic floods submerged more than a third of Bangladesh. Record-shattering heat waves killed scores of people in Europe and China.   These were among 15 extreme weather events in 2017 that were made more likely by human-cased climate change, according to
