Canada’s digital cybersecurity agency is warning the country’s “critical infrastructure” providers to be increasingly wary of attacks from Russia-backed hackers as tensions between the two countries increase over the threat of war in Ukraine, reports the National Post. Experts say those attacks could come in a range of forms, from a “widespread ransomware attack” to a “single, carefully focused” attempt to significantly affect core infrastructure.

Scientists from Wageningen University and Research (WUR) and Indiana University have discovered that the increasing irrelevance of factual truth in public discourse is part of a groundswell trend that started decades ago. While the current "post-truth era" has taken many by surprise, the study shows that over the past 40 years, public interest has undergone an accelerating shift from the collective to the individual, and from rationality toward emotion.
Analyzing language from millions of books, the researchers...
An Israeli hospital today said preliminary research indicates a fourth dose of the coronavirus vaccine provides only limited defence against the Omicron variant, reports Medical Xpress. Sheba Hospital last month began administering a fourth vaccine dose to 274 medical workers – 154 who received a Pfizer-BioNtech vaccine and 120 others who received Moderna's. All had previously been vaccinated three times with the Pfizer-BioNtech vaccine. The clinical trial found that both groups showed increases in...
A team of researchers at Aarhus University in Denmark has found evidence that suggests feeling bored can be a factor in setting off sadistic behaviour, reports Medical Xpress. In their paper published in Journal of Personality and Social Psychology: Interpersonal Relations and Group Processes, the group describes their review of nine unique studies they looked at that involved the study of sadistic behaviour by people in different settings and what they found by doing so. Prior...
The tsunami threat around the Pacific from a huge undersea volcanic eruption receded on Sunday, but a massive ash cloud covering the tiny island nation of Tonga prevented surveillance flights from New Zealand from assessing the extent of damage, reports Aljazeera. Satellite images showed the spectacular eruption of the Hunga Tonga-Hunga Ha’apai volcano that took place on Saturday with a plume of ash, steam, and gas rising like a mushroom above the blue Pacific waters. A sonic...
Authorities in Russia say they have dismantled the ransomware crime group REvil, and charged several of its members, the BBC reports. The United States had offered a reward of up to $10 million for information leading to the gang members, following ransomware attacks. Russia's intelligence bureau FSB said the group had "ceased to exist". However, it does not appear that any Russian members of the gang will be extradited to the U.S. The agency said it had acted...
More than 20,000 new coronavirus cases have been reported each day on average in Massachusetts for the past week. But in the bowels of Boston, there is a hint that the Omicron-fueled surge may be on the verge of decline. That glimmer of hope comes from an unlikely place: wastewater. The coronavirus levels detected in samples from the Deer Island water treatment plant, which processes wastewater from communities around Boston and eastern Massachusetts, show a steep drop...
Every galaxy, including our Milky Way, has at its centre a massive black hole whose gravity influences the stars around it. Generally, the stars orbit around the black hole without incident, but sometimes a star will wander a little too close, and the black hole will "make a meal" of the star in a process astrophysicists have termed spaghettification. "Gravity around the black hole will shred these unlucky stars, causing them to be squeezed into...
Two Los Angeles police officers were fired for chasing Pokémon rather than fleeing robbers, court documents show. The pair were parked nearby when a radio call came in for officers to respond to a shop robbery, the BBC reports. But a review of their in-car camera footage showed they had been playing the video game Pokémon Go, and chose to pursue a nearby Snorlax – a relatively rare catch – instead of providing back-up. The pair denied...
What physical changes occur in the brain when a memory is made? A team of researchers at the University of Southern California has answered this question by inducing a memory in a larval zebrafish and mapping changes in their transparent heads with brain cells lit up like Times Square on New Year's Eve. After six years of research, they made the groundbreaking discovery that learning causes synapses, the connections between neurons, to proliferate in some areas and...
