China Unicom has become the latest Chinese telecommunications giant to be banned from the U.S. over "significant" national security and espionage concerns, the BBC reports.
The Federal Communications Commission (FCC) said it had voted unanimously to revoke authorization for the company's American unit to operate in the U.S.
The firm must stop providing telecom services in the U.S. within 60 days. Larger rival China Telecom had its licence to operate in the U.S. revoked in October.

A new cell phone app and lab kit have transformed a smartphone into a COVID-19/flu detection system. The detection system is among the most rapid, sensitive, affordable and scalable tests known – and can be readily adapted for other pathogens with pandemic potential including deadly variants of COVID and flu. It also provides a platform for inexpensive home-based testing.
Developed by a research team of UC Santa Barbara scientists and...
Ukraine President Volodymyr Zelensky has called on the West not to create panic amid the build-up of Russian troops on his country's borders, the BBC reports.
He told reporters that warnings of an imminent invasion were putting Ukraine's economy at risk.
On Thursday, U.S. President Joe Biden said he believed Russia could attack its neighbour next month.
Russia, however, denies it is planning to invade and on Friday its foreign minister said Moscow did not want war.

Elon Musk likes to have a focus – and this year, it looks like it might be robots. He told investors on a Tesla earnings call his nascent robot plans had "the potential to be more significant than the vehicle business, over time."
And they would be the most important things Tesla worked on this year, the BBC reports. The robot in question, part of a project dubbed Optimus, was previewed last year – to raised eyebrows...
With 192 lasers and temperatures more than three times hotter than the centre of the Sun, scientists hit – at least for a fraction of a second – a key milestone on the long road toward nearly pollution-free fusion energy.
Researchers at the National Ignition Facility at the Lawrence Livermore National Lab in California were able to spark a fusion reaction that briefly sustained itself – a major feat because fusion requires such high temperatures and pressures, it easily...
For millions of patients who have lost limbs for reasons ranging from diabetes to trauma, the possibility of regaining function through natural regeneration remains out of reach. Regrowth of legs and arms remains the province of salamanders and superheroes.
But in a study published in the journal Science Advances, scientists at Tufts University and Harvard University's Wyss Institute have brought us a step closer to the goal of regenerative medicine.
On adult frogs, which are naturally unable to...
The Internal Revenue Service's criminal investigators see cryptocurrencies and nonfungible tokens as ripe for fraud, including money laundering, market manipulation and tax evasion – and celebrities could get caught up in the agency's probes, reports Allyson Versprille of Bloomberg News.
Digital assets have been a growing concern for government agencies as they have become more mainstream, with regulators grappling over how to police the tokens and carry out enforcement activities to deter investors from engaging in criminal...
Google is being sued in the U.S. over accusations it deceived people about how to control location tracking, the BBC reports. The legal action refers to a widely reported 2018 revelation that turning off one location-tracking setting in its apps was insufficient to fully disable the feature.
It accuses Google of using so-called dark patterns, marketing techniques that deliberately confuse. Google said the claims were inaccurate and outdated.
The legal action was filed in the District of Columbia. Similar...

Since the discovery of the deep subseafloor biosphere in the mid-1990s, scientists have studied the conditions under which organisms thrive in this isolated and generally food-deprived environment and wondered which conditions set a limit to the existence of life.
In 2016, a group of international scientists set out to sea on board Japanese scientific drillship Chikyu to study the temperature limit of the deep subseafloor biosphere. Sediment samples were collected from...
If everyone between 40 and 85 years of age were active just 10 minutes more a day, it could save more than 110,000 U.S. lives a year, a large study reports.
"Our projections are based on an additional 10 minutes of moderate to vigorous physical activity," said lead researcher Pedro Saint-Maurice of the Metabolic Epidemiology Branch at the U.S. National Cancer Institute in Bethesda, Md. "If the walk is brisk, it counts."
Added exercise benefits all groups...
