Russia's military has fired a hypersonic ballistic missile and destroyed a big underground arms depot in western Ukraine, the defence ministry in Moscow has said.
If confirmed, it would be Russia's first use in this war of the Kinzhal, or Dagger, ballistic missile launched from the air, most likely by a MiG-31 warplane, the BBC reports.
President Vladimir Putin has repeatedly highlighted Russia's investment in hypersonic missiles, which can travel at more than five times the...
Russia has accused Canada of "kindergarten-level" diplomacy in a Twitter tiff over a social media post by Canada's United Nations mission.
The diplomatic spat is over a letter seeking support for a draft Russian resolution about aid in Ukraine, reports the BBC.
Canada posted the letter to Twitter with "suggested edits", which led to retweets from other UN missions.
A Russian diplomat has called it "Russophobic libel".
An image of the letter – annotated in red type –...
A brewer has created a virtual beer to highlight the extremes businesses will go to to grab a slice of the next big thing – the metaverse.
Heineken set up a virtual launch to promote the "product" – an experience described by one attendee as surreal, the BBC reports.
The metaverse does not yet exist but many believe people will one day spend their time in inter-connected virtual worlds, accessed via a virtual-reality headset.
The firm said it...
Many humans are good at recognizing when they get things wrong, but artificial intelligence systems are not. According to a new study, AI generally suffers from inherent limitations due to a century-old mathematical paradox.
Like some people, AI systems often have a degree of confidence that far exceeds their actual abilities. And like an overconfident person, many AI systems don't know when they are making mistakes. Sometimes it is even more difficult for an AI...
Unsealed files have revealed a plot by five people working on behalf of Chinese secret police to stalk and harass a U.S. military veteran running for Congress, and to spy on an artist, the BBC reports.
It is the first time, they say, a federal election campaign has been undermined in this way in America. The perpetrators went to "outrageous and dangerous" lengths to do so, the Department of Justice said.
Three of the accused have been...
The first global analysis of its kind estimates that if every country's cigarette taxes had met the World Health Organization's (WHO) recommendations, around 182,000 newborn deaths could have been averted in 2018.
Tobacco use can have direct and indirect effects on children's health. For example, smoking during pregnancy can cause premature birth, and exposure to second-hand smoke can cause lung conditions such as asthma.
In total, increased cigarette taxes could have averted around 231,000 deaths of children under one year...
She's arguably the greatest female basketball player of all time, and she's been detained in Moscow amid the war in Ukraine. Fans want to know why more people aren't paying attention, reports the BBC.

A masked gunman struck five times in nine days in New York and Washington DC. Two of the men died. One's tent was set on fire, after he was stabbed and shot.
On Tuesday, only two days after a multi-state manhunt was launched, DC police said a suspect had been arrested and charged with homicide.
DC's Metropolitan Police Department had posted photos of the suspect, offering a reward up to $55,000 for tips that led to his...
Our solar system has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class that contains Eris, Sedna, Quaoar, Ceres, and perhaps many more small bodies. These are defined approximately as bodies that orbit the Sun but that are not large enough (unlike regular planets) to gravitationally dominate their environments by clearing away material.
Astronomers wonder if there might be a ninth planet undiscovered but lurking in the outer reaches of...
Close the blinds, draw the curtains, and turn off all the lights before bed. Exposure to even moderate ambient lighting during nighttime sleep, compared to sleeping in a dimly lit room, harms your cardiovascular function during sleep, and increases your insulin resistance the following morning, reports a new Northwestern Medicine study.
"The results from this study demonstrate that just a single night of exposure to moderate room lighting during sleep can impair glucose and cardiovascular...
