How to edit WhatsApp messages after sending (and why it isn't working)

WhatsApp has released a new feature that allows users to edit messages after sending them. In recent years, several messaging apps have introduced features enabling users to unsend or edit messages with typos, grammatical errors, or wrong information. Most recently, Apple released the edit message feature for iMessage with a 15-minute time cap, and WhatsApp is following suit. Editing a message on WhatsApp is very easy. All users need to do is press and hold a message, then select the 'Edit' button from the pop-up menu. They can then change the message in the text field and resend it. The…

A paralyzed man can walk again using a groundbreaking mind-reading brain implant

12 years ago, Gert-Jan Oksam was in a biking accident. He emerged alive, but unable to use his legs due to a spinal cord injury. Today he can walk about 100 meters — or just over 300 feet— all on his own. Essentially, he's taught his spinal cord to work again thanks to some small implants in his back and brain, which have rehabilitated the connection between his legs and his mind. "I'm not walking to the grocery market yet, but I can for sure stand way better now," the 40 year old patient said during a press conference on…

"Superintelligence will be more powerful than other technologies humanity has had to contend with in the past," the OpenAI executives said. "We can have a dramatically more…

Covid vaccine effectiveness against omicron fell to 20% after 6 months: Study

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…

The 'Benjamin Button' effect: Scientists can reverse aging in mice. The goal is to do the same for humans

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…

Some concrete structures in Rome remain standing 2,000 years after construction. This is how the Romans did it

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…

ChatGPT gave better medical advice than real doctors in blind study

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.…

AI can identify and design good-looking cars by itself now

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…
