What is Web3? And is it the next phase of the internet?

In theory, Web3 will allow you to go online without the need for search engines such as Google or social media like Facebook. But some say Web3 is under the control of the venture capital industry. Web3 has become the latest buzzword to get tech and cryptocurrency enthusiasts talking. While some are excited at what is being dubbed as the next phase of the Internet, others, including Elon Musk and Jack Dorsey, have voiced their concerns over it. But what is Web3 and can this decentralised vision of the Internet work? What is Web3? Put simply, Web3 is an umbrella…

UK company develops solar power unit for use in Africa

A company has developed an affordable solar storage device to bring power to those in energy poverty. It was designed by AceOn Group, based in Telford, Shropshire, United Kingdom, for use in sub-Saharan Africa, where only half the population has access to electricity. The project also received funding after being developed to use a more eco-friendly form of battery. Experts said investing in the region will be a "win-win". Only 60% of Nigeria's population has access to electricity and often have to use noisy, polluting petrol generators during power cuts. Mark Thompson, managing director for AceOn Group, said the unit…

Omicron can hit fully vaccinated, Oxford study says

Two doses of the Oxford-AstraZeneca or Pfizer-BioNTech Covid-19 vaccines are substantially less effective at warding off omicron compared to previous variants of the coronavirus, scientists have found. However, the researchers were optimistic that a booster shot would improve immunity against the new, highly transmissible variant. In a new study announced on Monday, researchers from the University of Oxford tested blood samples of people 28 days after their second dose of either vaccine. When omicron was introduced to those samples, scientists reported "a substantial fall" in the neutralizing antibodies that fight off Covid compared to the immune responses seen against earlier…

Smartwatches and fitness trackers could detect Covid-19 before you even feel ill

Scientists have created an algorithm for smartwatches that can detect 80% of confirmed Covid-19 cases before or when patients are symptomatic. However, the algorithm can't differentiate between someone who's consumed alcohol, someone who is stressed or someone with a virus. It is hoped that this can eventually be used to determine whether someone needs to self-isolate or not, following clinical trials and the incorporation of additional data. Researchers created an algorithm to notify smartwatch wearers of stress, capturing events such as air travel, extended exercise, and illness. The new algorithm reads heart rate as a proxy for physiological or mental…

Coronavirus infects fat, may explain obesity link to severe Covid-19

The coronavirus can directly infect fat cells, a recent study awaiting peer review found. The finding may help explain why obese or overweight people are more vulnerable to severe Covid-19. Scientists need more data to determine if extra body fat independently raises a person's risk. More than two-thirds of American adults are obese or overweight, putting them at elevated risk of severe Covid-19 illness and death. Obesity in particular may triple the risk of hospitalization from the disease. But for most of the pandemic, scientists haven't understood why. While obesity-related conditions such as diabetes and heart disease can independently raise…

Pfizer says its booster shot neutralizes Omicron

BioNTech and Pfizer said on Wednesday a three-shot course of their Covid-19 vaccine was able to neutralise the new Omicron variant in a laboratory test, an early signal that booster shots could be key to protection against infection from the newly identified variant. The German and U.S. companies said two doses of their vaccine resulted in significantly lower neutralising antibodies but could still be protective against severe disease. "The first line of defence, with two doses of vaccination, might be compromised and three doses of vaccination are required to restore protection," BioNTech Chief Medical Officer Ozlem Tuereci said at a…

US govt, other state actors can access your messages on WhatsApp, Telegram, iMessage, others despite encryption. This is how

Having end-to-end encryption may not be enough cover for privacy when using popular encrypted messaging applications, because law enforcement can access your data when they want to. A Federal Bureau of Investigation (FBI) document prepared on January 7 has provided the kinds of user data various secure messaging apps can share at the request of law enforcement agencies. Titled “Lawful Access,” the one-page document detailed the “FBl’s ability to legally access secure messaging app content and metadata.” The “unclassified” document designated as “for official use only” and “law enforcement sensitive” was prepared by the FBI’s science and technology branch and…

'Potentially hazardous' asteroid worth nearly $5bn will enter Earth’s orbit this week - NASA

A gigantic, "potentially hazardous" space rock bigger than the Eiffel Tower will enter Earth’s orbit next week, according to NASA. The egg-shaped asteroid, named 4660 Nereus, is 1,082 feet (330 meters) long and will break into Earth’s orbit traveling at 14,700 mph (23,700 km/h) on Saturday, Dec. 11. Thankfully for all of our weekend plans, the asteroid is expected to skim past Earth at some distance without making impact, but it will still be closer to us than it has been in 20 years. Nereus will be roughly 2.4 million miles away (3.86 million km), around 10 times the distance…
