Hurricane Dorian has been unleashing an impressive lightning storm as it continues on its tragically destructive way. Looping together satellite images from the end of August, meteorologist Dakota Smith has put together a spectacular show of flashing lights within and around the storm’s swirling eye. “I created the loop mainly to visualise how incredible hurricanes

A team of researchers has just demonstrated quantum enhancement in an actual X-ray machine, achieving the desirable goal of eliminating background noise for precision detection. The relationships between photon pairs on quantum scales can be exploited to create sharper, higher-resolution images than classical optics. This emerging field is called quantum imaging, and it has some

Last Wednesday, a gravitational wave detection gave astronomers quite the surprise. As researchers were going about their work at the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of gravitational waves rolled in just minutes apart. The first, labelled S190828j, was picked up by all three of LIGO’s gravitational wave detectors at 06:34 am, coordinated universal time. The

Sounds like the Defense Advanced Research Projects Agency (DARPA) was just kicked out of mom’s basement. In an inexplicable tweet, DARPA asked for help finding “commercially managed underground urban tunnels and facilities able to host research and experimentation.” And nobody knows why. The ideal space would be a human-made underground environment spanning several city blocks w/

Examples of how human societies are changing the planet abound – from building roads and houses, clearing forests for agriculture and digging train tunnels, to shrinking the ozone layer, driving species extinct, changing the climate and acidifying the oceans. Human impacts are everywhere. Our societies have changed Earth so much that it’s impossible to reverse

Across the Caribbean this week, island residents docked boats, emptied grocery stores, and boarded up buildings in preparation for Hurricane Dorian, which became a Category 1 storm on Wednesday. Meanwhile, high up in Earth’s orbit, satellites belonging to the National Oceanic and Atmospheric Administration (NOAA) watched the hurricane form and churn. The storm has passed

Here’s a simple how-to on how to construct a traversable cosmic wormhole that could send your spaceship to the furthest reaches of space: take two charged black holes, place them back to back, and thread two cosmic strings through both. Stretch both strings to infinity and presto! You’ve got yourself a traversable wormhole. Confused yet?

Fires in the Amazon rainforest have captured attention worldwide in recent days. Brazilian President Jair Bolsonaro, who took office in 2019, pledged in his campaign to reduce environmental protection and increase agricultural development in the Amazon, and he appears to have followed through on that promise. The resurgence of forest clearing in the Amazon, which

After what SpaceX’s founder Elon Musk called an “embarrassing” glitch with Starhopper, an experimental rocket ship, the company pulled off an impressive launch and landing on Tuesday. “Congrats SpaceX team!!” Musk tweeted shortly after the attempt. “One day Starship will land on the rusty sands of Mars.” Starhopper is a roughly 60-foot-tall (18 meters) vehicle

An international team of scientists trying to save the northern white rhino from extinction has just announced another significant victory. Yesterday we reported that 10 eggs had been successfully harvested from the two surviving females Najin and Fatu. Now, scientists have revealed that of those eggs, seven were successfully matured and artificially inseminated using a technique

“Why don’t we nuke them?” President Donald Trump asked during a White House briefing about hurricanes, according to an Axios report. Trump was advocating for a nuclear solution to the tropical storms that hit the southeastern US, according to Axios [although Trump has since denied the comment]. Sources who heard the president’s private remarks told
