Hundreds of elephants that died mysteriously in Botswana’s famed Okavango Delta probably succumbed to natural toxins, the wildlife department said Friday. ​The landlocked southern African country has the world’s largest elephant population, estimated to be around 130,000. Around 300 of them have been found dying since March.   ​Authorities have so far ruled out anthrax,

Not all volcanoes are suddenly explosive. Some spew steady rivers of gloppy, slow-moving lava for millennia on end, like those in the Hawaiian or Galápagos islands. These are what volcanologist Michael Stock from Trinity College Dublin in Ireland calls the ‘boring’ volcanoes – yet underneath their monotonous exterior, lurks a bombshell that Stock and his colleagues

After travelling more than 27 million miles around planet Earth, NASA astronauts Bob Behnken and Doug Hurley are headed home inside SpaceX’s new Crew Dragon spaceship. Despite the threat of Hurricane Isaias strafing coastal Florida with brutal weather, the two-man crew undocked their ship from the International Space Station Saturday evening, beginning the return of the first

On Thursday morning, NASA will launch its fifth Mars rover: A robotic scientist the size of an SUV. The $US2.4 billion, nuclear-powered vehicle, named Perseverance (“Percy” for short) is designed to trundle along the Martian surface, mine for signs of ancient life, capture high-quality video and audio, and collect rock and soil samples for an eventual return

Fourteen years after receiving the official go-ahead, scientists on Tuesday began assembling a giant machine in southern France designed to demonstrate that nuclear fusion, the process which powers the Sun, can be a safe and viable energy source on Earth.   The groundbreaking multinational experiment, known as the International Thermonuclear Experimental Reactor (ITER), has seen components arrive

Common chemicals nicknamed ‘forever chemicals‘ for their tendency to stick around in the environment for a disconcertingly long time have been detected in Arctic seawater. PFAS (per and polyfluoroalkyl substances) chemicals are used in a lot of household products. While the effects of PFAS on human health are still being debated, they have been detected in

Scientists have developed an experimental device and protocol for manipulating the content of people’s dreams while they are sleeping, by making them recall specific cues that can trigger targeted dream themes and experiences.   While the boundless dream-building of Inception remains the stuff of science fiction for now, the new research shows that the evolving

Norway’s Arctic archipelago Svalbard on Saturday recorded its highest-ever temperature, the country’s meteorological institute reported. According to scientific study, global warming in the Arctic is happening twice as fast as for the rest of the planet.   For the second day in a row, the archipelago registered 21.2 degrees Celsius (70.2 Fahrenheit) in the afternoon,

We have developed four-winged bird-like robots, called ornithopters, that can take off and fly with the agility of swifts, hummingbirds and insects. We did this by reverse engineering the aerodynamics and biomechanics of these creatures.   Our ornithopters have the potential to outperform and outmanoeuvre existing drone configurations with static wings or propellers. What are
