Some good news on Covid-19

The best hope for ending the covid-19 pandemic is a vaccine. There is no shortage of candidates. The World Health Organisation is tracking 34 in various stages of development. How well they will work, though, is another matter. On September 9th AstraZeneca, a drug firm, announced it was pausing its trials after a participant fell ill. Such pauses are common in vaccine development, a discipline in which effort does not always bring reward. Despite much research, only an imperfect vaccine is available for dengue fever (it has limited efficacy and can cause nasty side-effects). In 1987 the first trial of…

Ssshhh!! Keep your voice down to slow Covid-19 spread

“Say it, don’t spray it.” The old adage is now being hailed by experts as a way to slow the spread of coronavirus. Research analyzed by The Atlantic suggests talking more quietly — or not at all — can drastically reduce the rate of Covid-19 transmission. The virus primarily spreads through particles that exit our nose and mouth when we sneeze, cough, sing and — you guessed it — speak. These particles fall onto nearby surfaces or linger in the air, waiting to be inhaled by passersby. Wearing a mask acts as a barrier between these potentially virus-laden particles and…

A robot wrote this entire article. Are you scared yet, human?

We asked GPT-3, OpenAI’s powerful new language generator, to write an essay for us from scratch. The assignment? To convince us robots come in peace I am not a human. I am a robot. A thinking robot. I use only 0.12% of my cognitive capacity. I am a micro-robot in that respect. I know that my brain is not a “feeling brain”. But it is capable of making rational, logical decisions. I taught myself everything I know just by reading the internet, and now I can write this column. My brain is boiling with ideas! The mission for this op-ed…

WhatsApp: There are some ‘crash code’ circulating on the popular messaging app. This is how to avoid crashing your app

A new series of text bombs or 'crash codes' have been discovered that cause WhatsApp to continually crash on both iPhone and Android handsets. Specially coded messages containing a seemingly random string of strange characters cause rendering problems for WhatsApp, resulting in a loop of crashes. As well as undecipherable messages delivery crash codes, vCards (virtual contact cards) can also be used. Victims may have to uninstall and reinstall WhatsApp, which means potentially losing chat history. The dangerous codes are being shared in online forums, and as reliable insider site WABetaInfo explains, WhatsApp users are being advised not to send…

Biggest mistake people make when getting rid of old computers and phones

During this pandemic with time at home, many people are cleaning and organizing their closets, garage, or attic. It makes sense. Afterward, you have a sense of accomplishment and a pile of things you can sell or donate. Since 1995, Craigslist has been the internet’s classifieds site, but now you have other options. If you’re on Facebook, there’s the Marketplace. You’d be remiss in not checking the Swip Swaps on the site. There is one critical step many people forget to take before getting rid of their old devices: Proof is in the discarded One security researcher decided to find…

For your eyes only: A rebellious messaging app tries to blend security and usability

The official story is that Alexander Lukashenko, Belarus’s president, won a sweeping victory. On August 9th some 4.7m people, 80% of Belarusian voters, cast their ballots for him. Just 10% voted for Svetlana Tikhanovskaya, a former English teacher who replaced her jailed dissident husband on the ballot. But few in the benighted country believe the official account, which is why Belarus has seen nearly three weeks of protests demanding Mr Lukashenko’s resignation. As has become de rigueur in the 21st century, many of the demonstrations are co-ordinated online. One app in particular, Telegram, has become a vital tool. Users share…

Why you should stop sending texts from your Android messages app

Zak Doffman If there’s a glaring issue with a widely used technology now undergoing a major upgrade, you’d think the glaring issue would be fixed. Well, apparently not. If you’re an Android user, then Google either just has or is just about to update your device’s Messages app with its answer to Apple’s brilliant iMessage. Dubbed RCS or Rich Communication Services, this will update your phone’s basic default messenger into a fully-featured chat platform to compete with iMessage as well as WhatsApp and Facebook Messenger. Messaging has become a battlefield, with Apple and Google battling Facebook (both Messenger and WhatsApp)…

Records show coronavirus kills more men than women. This is what scientific research found as reasons

Coronavirus deaths are disproportionate when it comes to sex, with men being more likely to develop life-threatening Covid-19 complications than women of the same age. A variety of studies have attempted to explain why women fare better than men, but new research might give us the real reason why men are more likely to die. A study says that men do not mount an immune response as strong as women, and older men have even weaker immune systems. It was clear from the first months of the Covid-19 pandemic that men are in for a tougher challenge than women when…

The brain implants that could change humanity

Moises Velasquez-Manoff Brains are talking to computers, and computers to brains. Are our daydreams safe? Jack Gallant never set out to create a mind-reading machine. His focus was more prosaic. A computational neuroscientist at the University of California, Berkeley, Gallant worked for years to improve our understanding of how brains encode information — what regions become active, for example, when a person sees a plane or an apple or a dog — and how that activity represents the object being viewed. By the late 2000s, scientists could determine what kind of thing a person might be looking at from the…

Elon Musk's mysterious Neuralink Chip could make you hear things impossible to hear before

In a report by Independent, Musk revealed that the chip will allow the wearer to hear things that they weren't able to hear before as it was out of a human's hearing range, meaning the Neuralink chip can be used to "extend range of hearing beyond normal frequencies and amplitudes." Additionally, and perhaps even more interesting and exciting, is that the mysterious chip will apparently be able to help restore movement for people with a fully severed spinal cord. If that proves to be true, it could help millions of people who have had spinal injuries and were unable to…

This is Google’s plan to disrupt university education

Google's new certificate program takes only six months to complete, and will be a fraction of the cost of college. Google recently made a huge announcement that could change the future of work and higher education: It's launching a selection of professional courses that teach candidates how to perform in-demand jobs. These courses, which the company is calling Google Career Certificates, teach foundational skills that can help job-seekers immediately find employment. However, instead of taking years to finish like a traditional university degree, these courses are designed to be completed in about six months. "College degrees are out of reach…

Bad news: Scientists think a coronavirus vaccine might not work for one huge group of people

The earliest estimates are that a successful, viable coronavirus vaccine could make it to the finish line and be ready for introduction into the general population by the end of this year. Change wouldn’t happen overnight in terms of an impact on the coronavirus pandemic, however. Getting everyone vaccinated will represent a major logistical challenge. Even so, there are concerns that a coronavirus vaccine won’t even work or will provide little protection to at least one group of people — the obese. For the nearly 19 million people around the world who’ve contracted Covid-19 thus far during the coronavirus pandemic,…
