In collaboration with a team at the Federal Reserve Bank of Boston, MIT experts have begun designing and testing technical research through which further examination of a Central Bank Digital Currency (CBDC) can be performed in the U.S.
The effort, known as Project Hamilton, is in an exploratory phase, and the research is not intended as a pilot or for public deployment. Instead, the researchers have explored two approaches that could be used to process...

Queensland University of Technology PhD researcher Lauren Ashwood has studied sea anemones' venom makeup extensively, in particular, Telmatactis stephensoni a reef-based sea anemone that can grow from 8-10 cm.
Ashwood found that this species produced different venoms for biological functions – defense, predation, and digestion – and that the toxins were located at sites that corresponded to their function.
"Unlike snakes, which deliver their venom via fangs, T. stephensoni venom is a complex cocktail of...
Psychoactive drugs include all manner of hallucinogens, deliriants, hypnotics, and psychedelics. But what is a psychedelic, really? Insofar as many in the field are now moving toward bringing new molecules with presumably desirable introspective properties into a larger, potentially druggable populace, there is a palpable need for increased clarity, reports Medical Xpress.
There is a curious push to define psychedelics as compounds that alter consciousness by acting on serotonin receptors in the brain, most notably 5-HT2A receptors. However,...
Meta has announced a new feature to allow more personal space for people's avatars in virtual-reality worlds.
The metaverse is still at concept stage, but the latest attempts to create virtual worlds are already facing an age-old problem: harassment.
Bloomberg's technology columnist Parmy Olson told the BBC's Tech Tent program about her "creepy" experiences.
And one woman likened her own traumatic experience in VR to sexual abuse.
Meta has now announced a new feature, Personal Boundary, which begins...
High doses of a widely used drug used in the hormonal treatment of conditions such as excessive hair growth, early puberty, and prostate cancer, are linked to an increased risk of meningioma – the most common type of benign brain tumour, finds a University of Bristol-led study of over 8 million patients. The study is published in Scientific Reports.
Typically slow growing, meningiomas are benign tumours that are often revealed incidentally by imaging but can cause significant...
University of Delaware (UD) engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen.
It is a significant advance for carbon dioxide capture and could bring more environmentally friendly fuel cells closer to market, writes Karen Roberts of the University of Delaware.
The research team, led by UD professor Yushan Yan, reported its method in Nature Energy today.
Fuel cells work by converting fuel chemical energy directly into electricity. They can be used in...
Social media giant Facebook has seen its daily active users (DAUs) drop for the first time in its 18-year history, the BBC reports.
Facebook's parent company Meta Networks says DAUs fell to 1.929 billion in the three months to the end of December, compared to 1.930 billion in the previous quarter.
The firm warned of slowing revenue growth in the face of competition from rivals including TikTok and YouTube, while advertisers are also cutting spending.
Meta's shares...
Mobile phone companies' 5G networks are bringing more speed and innovation to consumers, but there is at least one trade-off: to open up airwaves for 5G, the companies are shutting down older networks that many devices and services still use, reports Jon Healey of the Los Angeles Times.
Those older 3G networks were heralded as a revolutionary advancement in bandwidth and connectivity when they debuted in the United States in 2002. Although 3G (short for third generation)...
A major fuel supplier in Germany is operating at a "limited capacity" after a cyber attack disrupted IT systems on the weekend, the BBC reports.
Oiltanking Deutschland GmbH & Co. KG stores and transports oil, vehicle fuels, and other petroleum products for companies including Shell.
It says it discovered it had been hacked on Saturday.
It has declared "force majeure" for the majority of its inland supply activities in Germany. The declaration of force majeure excuses a company...
Being overweight or obese has long been linked to poor heart health, but could it also impair your thinking?
New research out of Canada suggests it very well might.
Working with thousands of young, middle aged, and older adults, the new study highlights what appears to be fat's direct harm on one's ability to think quickly, with rising body fat levels linked to diminishing mental health returns.
"Our findings are intriguing, because we show that , as it increases, not...
