Covid-19 vaccine effectiveness against omicron infection fell to less than 20% after six months, according to a new analysis published Wednesday. Researchers from Italy and the United States looked at some of the most common vaccines used around the world, including Pfizer-BioNTech, Moderna, AstraZeneca and Sinovac. The researchers, however, did not look at the updated bivalent vaccines that target the original strain of the virus as well as BA.4 and BA.5, which are subvariants of omicron. For the analysis, published in JAMA Network Open, the team examined 40 studies -- a combination of articles and reviews published in peer-reviewed journals…
In molecular biologist David Sinclair’s lab at Harvard Medical School, old mice are growing young again. Using proteins that can turn an adult cell into a stem cell, Sinclair and his team have reset aging cells in mice to earlier versions of themselves. In his team’s first breakthrough, published in late 2020, old mice with poor eyesight and damaged retinas could suddenly see again, with vision that at times rivaled their offspring’s. David Sinclair has reversed aging in mice and believes the same can be done for people. - Courtesy Richard Groleau “It’s a permanent reset, as far as we…
The ancient Romans were brilliant engineers and builders, creating a dazzling array of magnificent structures including some that have survived to modern times virtually intact like the domed Pantheon in Rome. An indispensable material for the Romans was a form of concrete they developed that is known for remarkable durability and longevity, though its exact composition and properties have remained a mystery. A new study goes a long way toward solving this puzzle and, the researchers said, could pave the way for the modern use of a replicated version of this ancient marvel. Roman concrete was introduced in the 3rd…
When it comes to answering medical questions, can ChatGPT do a better job than human doctors? It appears to be possible, according to the results of a new study published in JAMA Internal Medicine, led by researchers from the University of California San Diego. The researchers compiled a random sample of nearly 200 medical questions that patients posted on Reddit, a popular social discussion website, for doctors to answer. Next, they entered the questions into ChatGPT (OpenAI’s artificial intelligence chatbot) and recorded its response. A panel of health care professionals then evaluated both sets of responses for quality and empathy.…
Automakers spend tens of millions of dollars and thousands of hours each year trying to come up with the next popular automotive design, but what if they could do for a fraction of the cost in minutes? That’s what General Motors and the MIT Sloan School of Management tried to find out in a recent study. Sloan marketing professor John Hauser told Fox News Digital that a neural network was trained with data collected from General Motors clinics by inputting images and the scores given by attendees. "These were actually evaluations from consumers in theme clinics of what they thought…
WhatsApp is finally rolling out multi-device login support for more than one phone. Mark Zuckerberg announced the feature’s rollout on Facebook and Instagram. “Starting today, you can log into the same WhatsApp account on up to four phones,” he said. WhatsApp said that this feature is rolling out to all users within the coming weeks. Until now, users could only use one WhatsApp account on one phone and multiple companion desktop devices. With the new rollout, users’ messages will be synced across devices including other phones. So even if one device is switched off, they can access the app on…
Billionaire tech mogul Elon Musk revealed he will start his own version of an artificial intelligence chatbot, coined "TruthGPT," during an exclusive interview with Fox News' Tucker Carlson. The Twitter and Tesla CEO sat down with Carlson for an interview to discuss why he will establish an alternative to ChatGPT, an AI app developed by progressive programmers that he helped initially fund, and the broader concerns he has about how the software can affect freedom of information. "I'm going to start something which I call TruthGPT, or a maximum truth-seeking AI that tries to understand the nature of the universe,"…
Smartphone innovation has come a long way. A lot of the tasks that used to require separate tech gadgets can now be done on your smartphone—something companies love bragging about in their ads and launch events. But as great as it is to have all those bleeding-edge specs and features inside a handheld device you can carry everywhere, do you need them? Do they actually make a difference? Let's take a look at some overhyped features you can ignore when buying a new phone. 1. 8K Video Recording We've had 4K video recording (3840 x 2160 pixels) on smartphones for…
A malaria vaccine called R21/Matrix developed by scientists at Oxford University has received approval to be used in Ghana. TheCable had reported that the vaccine was said to be 80 percent effective in preventing malaria. The only vaccine currently endorsed for malaria by the World Health Organisation (WHO) is the RTS, S/AS01 (RTS,S) vaccine which is 29 percent effective in preventing severe malaria. In a statement on Thursday, Oxford University said this is the first time its vaccine has received regulatory clearance anywhere in the world. The university said the vaccine has demonstrated high levels of efficacy and safety in…
On April 9, on the occasion of the Russian Day of Air Defense Forces, an official revealed that the Russian military was deploying the cutting-edge technology of ‘Niobium’ radar in Ukraine, which is used to detect aircraft, helicopters, drones, ballistic missiles, and MLRS rockets.
