Increases in depression without commensurate increases in treatment are widespread, reports a study conducted at Columbia University Mailman School of Public Health and City University of New York. In 2020, past 12‒month depression was prevalent among nearly 1 in 10 Americans and almost 1 in 5 adolescents and young adults. The findings will be published online in the American Journal of Preventive Medicine.
Data were drawn from the 2015−2020 National Survey on Drug Use and Health,...
High body mass index (BMI), rather than high blood sugar levels, are associated with excess risks of COVID-19 infection and long COVID, according to a meta-analysis of more than 30,000 U.K. adults from nine large prospective cohort studies.
The findings by Dr. Anika Knuppel from the MRC Unit for Lifelong Health and Ageing, University College London, U.K., and colleagues are being presented at this year's European Association for the Study of Diabetes (EASD) annual meeting...
Hackers have told the BBC they carried out a destructive cyber-attack against Holiday Inn owner Intercontinental Hotels Group (IHG) "for fun."
Describing themselves as a couple from Vietnam, they say they first tried a ransomware attack, then deleted large amounts of data when they were foiled.
They accessed the FTSE 100 firm's databases thanks to the easily found and weak password "Qwerty1234".
One expert says the case highlights the vindictive side of criminal hackers.
U.K.-based IHG operates 6,000...
Leading cryptocurrency figures hailed on Thursday the completion of one of the biggest software upgrades the sector has ever attempted – an overhaul of the Ethereum blockchain aimed at reducing its massive energy consumption.
Developers had spent years working on an energy-efficient version of Ethereum, a digital ledger that underpins tens of billions of dollars worth of cryptocurrencies, digital tokens (NFTs), games, and apps, writes Joseph Boyle of Tech Xplore.
Ethereum is the second most important blockchain...
Vladimir Putin has acknowledged China's "concern" over Ukraine, in his first face-to-face talks with President Xi Jinping since the Russian invasion.
But speaking in Uzbekistan, Putin also thanked China for its "balanced position," and said U.S. "attempts to create a unipolar world" would fail, the BBC reports.
Xi said China was willing to work together with Russia as "great powers."
China has not endorsed Russia's invasion but has grown trade and other ties with Moscow since it...
A South Korean court has issued an arrest warrant for Do Kwon, who co-founded the company behind the Terra Luna and TerraUSD cryptocurrencies.
Their spectacular collapse earlier this year spooked investors and saw the values of major tokens plummet.
Prosecutors claim that Terraform Labs, which is registered in Singapore, had violated capital market rules.
Terra Luna lost 99% of its value in May, and this was aggravated by a fall of its sister token, TerraUSD.
Kwon did not...

He called for Russia to respect the sovereignty of Ukraine.
The chancellor has come under pressure to increase military support for Kyiv.

Instead of sitting in a tattoo chair for hours enduring painful punctures, imagine getting tattooed by a skin patch containing microscopic needles. Researchers at the Georgia Institute of Technology have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics.
"We've miniaturized the needle so that it's painless, but still effectively deposits tattoo ink in the skin," said Mark Prausnitz, principal investigator on...
If you're going to break a rule with style, make sure everybody sees it. That's the goal of engineers at Rice University who hope to improve screens for virtual reality, 3D displays, and optical technologies in general.
Gururaj Naik, an associate professor of electrical and computer engineering at Rice's George R. Brown School of Engineering, and Applied Physics Graduate Program alumna Chloe Doiron found a way to manipulate light at the nanoscale that breaks the...
A global search for alternative sources to Russian energy during the war in Ukraine has refocused attention on smaller, easier-to-build nuclear power stations, which proponents say could provide a cheaper, more efficient alternative to older model mega-plants, Tech Xplore reports.
U.K.-based Rolls-Royce SMR says its small modular reactors, or SMRs, are much cheaper and quicker to get running than standard plants, delivering the kind of energy security that many nations are seeking. France already relies...
