NASA astronauts Bob Behnken and Doug Hurley, who made spaceflight history on May 30 by becoming the first people to launch to orbit aboard a SpaceX vehicle, might see their weekend homecoming plans thrown to the wind. After docking SpaceX’s Crew Dragon Endeavour ship to the International Space Station and spending two months there, the men are preparing to

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

Scientists are trying a little bit of everything to fight the virus that causes COVID-19, but some researchers are harnessing more than just the usual virus-fighting repertoire, from tiny sponges to viral RNA-destroying bubbles.

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 in

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 science

A first-of-its-kind artificial intelligence (AI) study of romantic relationships based on data from thousands of couples has identified the top predictors that make partners feel positively about their relationship – and the findings show romantic happiness is about a lot more than simply who you’re with. Researchers conducted a machine-learning analysis of data collected from

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, just

When faced with threats ranging from snake bites to COVID infections, some white blood cells retaliate with a peculiar tactic: spewing out their own DNA to form pathogen-trapping nets. But research suggests that sometimes this web-deploying response might do our bodies more harm than good. Hosted by: Stefan Chin SciShow has a spinoff podcast! It’s

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 ornithopters?

As plants begin to spread across melting permafrost, scientists are growing ever more worried their roots will stir microbes into unleashing vast stores of carbon. To scientists, roots are known as rhizomes, and when these tendrils extend deeper into the soil, it accelerates microbial decomposition by up to fourfold, potentially ‘priming’ the frozen ground for

Nearly a century after experiments confirmed that atoms, matter’s smallest building blocks, have ethereal, wave-like characteristics, physicists have just found a new way to show how mammoth-sized molecules ripple with the same uncertainty. Researchers from the University of Vienna and the University of Duisburg-Essen, Germany, put a new spin on a classic experiment to create

Humans know a lot about bees, seeing as they impact both our ecology and our economy. But there’s something about bumble bees that we totally missed until recently; a super weird and mysterious behavior that might give them a leg up in weathering climate change.

US officials and scientists have begun laying the groundwork for a more secure “virtually unhackable” internet based on quantum computing technology. At a presentation Thursday, Department of Energy (DOE) officials issued a report that lays out a blueprint strategy for the development of a national quantum internet, using laws of quantum mechanics to transmit information
