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 Google said the claims were inaccurate and outdated.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...
Facebook's parent company Meta announced today it is launching one of the world's most powerful supercomputers to boost its capacity to process data, Tech Xplore reports. The U.S. tech giant said the array of machines could process images and video up to 20 times faster than its current systems.
The supercomputer, built from thousands of processors, will be used to "seamlessly analyse text, images, and video together; develop new augmented reality tools; and much more",...
Global Affairs Canada is scrambling to recover after a multi-day network disruption that security and government sources describe as a “cyber attack”, Global News reports. While neither Global Affairs nor Canada’s cyber security agency, the Communications Security Establishment, could immediately comment, sources tell Global News the government is concerned the attack was conducted by Russia or Russian-backed hackers. "GAC has been the target of a cyber attack, but it is not clear if the Russians, the...
In her latest research paper, published in the Journal of Molecular Neuroscience, Anne Robinson, head of Carnegie Mellon's Department of Chemical Engineering, explains why understanding the progression of neurodegeneration in Alzheimer's disease, and its eventual treatment, is much more complex than researchers have previously thought.
One in 10 Americans over the age of 65 suffer from Alzheimer's, rising to one in three in those over 80. It is the sixth-leading cause of death in the United...
Netflix delivered its latest quarter of disappointing subscriber growth during the final three months of last year, a trend that management foresees continuing into the new year as tougher competition undercuts the video streaming leader, Tech Xplore reports.
The Los Gatos, California, company added 8.3 million subscribers worldwide during the October-December period, about 200,000 fewer than management had forecast. Besides releasing its fourth-quarter results Thursday, Netflix projected an increase of 2.5 million subscribers during the...
