Russian President Vladimir Putin has said he is ready to use nuclear weapons to defend Russian territory, raising the fear he might use a small, or "tactical" nuclear weapon in Ukraine.
U.S. President Joe Biden has warned that doing so would be the most serious military escalation since World War II, the BBC reports.
Tactical nuclear weapons are small nuclear warheads and delivery systems intended for use on the battlefield, or for a limited strike.
They are designed...
A team of space scientists affiliated with multiple institutions in the U.S., working with a colleague from Italy and another from France has used modeling to partially explain the resilience of cyclones circling Jupiter's poles. In their paper published in the journal Nature Astronomy, the group describes how they analyzed images captured by the Juno space probe and used what they learned to create shallow water models that might at least partly explain how the...
Hurricane-strength Fiona is ripping through Canada's eastern seaboard after making landfall in Nova Scotia early Saturday, slamming the area with fierce rain and damaging winds, and knocking out power for hundreds of thousands in what could be a "landmark" weather event for the country.
Fiona, now a post-tropical cyclone, had maximum sustained winds of 85 mph -- the power of a Category 1 hurricane -- at 8 a.m. ET Saturday, with its centre over the...
About five minutes after the 7.6 magnitude earthquake hit near Mexico's southwest coast Monday, typically calm water deep in a Death Valley National Park cave started sloshing against the surrounding limestone rock, reports Grace Toohey at Phys.org.
The reverberations from the earthquake more than 2,400 kilometres away created what experts have called a "desert tsunami," which on Monday made waves erupt up to over a metre high in the cave known as Devils Hole, a pool of...
Tesla is recalling nearly 1.1 million cars in the U.S. because the windows might close too fast and pinch people's fingers.
Documents produced by American regulators show the windows may not react correctly after detecting an obstruction.
Tesla chief executive Elon Musk criticized the description as a recall, calling it "outdated and inaccurate".The car giant says a software update will fix the problem.
The National Highway Traffic Safety Administration says the fault is a safety-standards violation.

Scientists have engineered mosquitoes that slow the growth of malaria-causing parasites in their gut, preventing transmission of the disease to humans.
The genetic modification causes mosquitoes to produce compounds in their guts that stunt the growth of parasites, meaning they are unlikely to reach the mosquitoes' salivary glands and be passed on in a bite before the insects die.
So far, the technique has been shown to dramatically reduce the possibility of malaria spread in a lab setting, but if...
Lebanese banks will remain shut "indefinitely" due to a lack of security protection by authorities, say their association.
The announcement by the Association of Lebanese Banks follows a string of raids by customers demanding access to frozen savings last week, the BBC reports.
It said their employees faced risks that had not been mitigated.
A woman armed with a toy gun reportedly staged a hold-up at a bank on Wednesday to pay for family medical bills.
