Another record has been broken on the way to fully operational and capable quantum computers: the complete control of a 6-qubit quantum processor in silicon. Researchers are calling it “a major stepping stone” for the technology. Qubits (or quantum bits) are the quantum equivalents of classical computing bits, only they can potentially process much more

Queen Elizabeth’s newly released death certificate contains just two curious words under her cause of death – old age. We might talk about people dying of old age in everyday speech. But who actually dies of old age, medically speaking, in the 21st century? Such a vague cause of death not only raises questions about

This year marks the 100-year anniversary of the discovery of Tutankhamun’s tomb and, even after all this time, the famous burial site is still revealing its secrets and stirring up controversy. A renowned British Egyptologist and former British Museum curator claims to have found evidence that the tomb’s royal murals and hieroglyphics might have been

Based on its market share, the world’s most notorious cryptocurrency Bitcoin results in more climate damage than the production of beef and nearly as much damage as crude oil, researchers in the United States have calculated. The findings of the new three-pronged analysis suggest Bitcoin is potentially unsustainable and could have disastrous social and environmental

WAILEA, Hawaii — Ahead of a Federal Communications Commission vote on a proposal to set a five-year deadline for deorbiting low Earth orbit satellites, leaders of the House Science Committee are questioning the FCC’s authority to do so. FCC commissioners will take up at their Sept. 29 open meeting a proposal released earlier in the

Yesterday, humanity achieved a new and amazing first, 11 million kilometers (6.8 million miles) from home. After years of planning, NASA’s Double Asteroid Redirection Test (DART) finally slammed into a moonlet, Dimorphos, orbiting an asteroid, Didymos, in our first ever attempt to redirect the path of a significantly sized cosmic object. The images of the

Lakes appearing in Alaska because of melting permafrost are “belching” methane into the atmosphere, a scientist working with NASA said. These lakes, called thermokarsts, are so full of the climate-damaging gas that it can be seen bubbling to the surface. More and more of these lakes are appearing as Alaska’s permafrost thaws with rising temperatures

LAUREL, Md. — A NASA spacecraft collided with a moon orbiting a near Earth asteroid Sept. 26 in a demonstration of a technology that could one day be used to protect the Earth from a hazardous object. NASA’s Double Asteroid Redirection Test (DART) spacecraft hit Dimorphos, an asteroid about 160 meters across orbiting the larger

More than eight months after the underwater volcano near Tonga erupted on Jan. 14, scientists are still analyzing the impacts of the violent blast, and they’re discovering that it could warm the planet. Recently, researchers calculated that the eruption of Hunga Tonga-Hunga Ha’apa spewed a staggering 50 million tons (45 million metric tons) of water

A woman in labor is having a terrible time and suddenly shouts out: “Shouldn’t! Wouldn’t! Couldn’t! Didn’t! Can’t!” “Don’t worry,” says the doctor. “These are just contractions.” Until now, several theories have sought to explain what makes something funny enough to make us laugh. These include transgression (something forbidden), puncturing a sense of arrogance or

In the wacky gravitational environment in the heart of our galaxy, astronomers have found a gas blob orbiting our supermassive black hole at superspeed. Its characteristics are helping astronomers probe the space immediately surrounding Sagittarius A* in the search for answers about why the galactic center flickers and flares across the entire electromagnetic spectrum. Their

PARIS — NASA said it completed all the objectives of a Space Launch System tanking test Sept. 21 despite the reoccurrence of liquid hydrogen leaks. The day-long test at Kennedy Space Center’s Launch Complex 39B involved filling the SLS core stage and upper stage with liquid hydrogen and liquid oxygen propellants, carrying out the “kickstart
