'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…

Eating just 1 hot dog takes 35 minutes off life - Study

Researchers released a nutritional index this week aiming to inform guidelines and help Americans achieve healthier and more environmentally stable diets. The index ranked foods by minutes gained or lost off healthy life per serving, with processed meats and sugary drinks among the biggest offenders. Findings included over 5,000 foods in the U.S. diet classified by health burden and environmental impacts. “We use the results to inform marginal dietary substitutions, which are realistic and feasible,” authors wrote. “We find that small, targeted, food-level substitutions can achieve compelling nutritional benefits and environmental impact reductions.” The foods studied ranged from 74 minutes…

Jack Dorsey: What's next for Twitter's co-founder?

Jack Dorsey is one of Silicon Valley's eccentrics. If he was a character in a movie, you'd think he was too cliche. Acutely earnest and idealistic, he passionately believes that tech can bring about global peace and prosperity. He's a kind of hippie libertarian, a philosophy that seems somewhat baffling at times. He also happens to be a genuine tech visionary. His resignation from Twitter is the second time he's left. After leaving the social media giant that he co-founded the first time, he setup the digital payments company Square in 2009 - which has become wildly successful. He came…

New technology tracks facial muscle movements to expose liars

When it comes to telling when someone is lying, we currently have very few options, but a team of Israeli researchers claims to have come up with something better than anything we’ve seen before. Using stickers printed on soft surfaces containing electrodes that monitor and measure the activity of muscles and nerves, a team of researchers led by Dino Levy from Tel Aviv University, discovered that some people involuntarily activate muscles in their cheeks and eyebrows when they lie. No sensors had been able to measure these subtle muscle contractions before, but the innovative ones invented by Yael Hanein and…

Apple to begin do-it-yourself repair program for iPhones, Macs next year

If you ever broke the screen on your iPhone , you had few options to fix it. You could go to Apple and pay the company to replace the part, which costs hundreds of dollars.

Your only other option would be to go to your local mall or alternative repair store. Repair advocates have long asked Apple to publish repair manuals and offer access to replacement parts.

One of the world’s poorest countries found a better way to do stimulus

Atani Bamaze was working his small plot of land, scything weeds down to the rust-colored soil, when he received a lifeline in the form of a text message. It was late 2020, and though Bamaze still didn’t know anyone sickened by Covid-19, the pandemic had disrupted his life all the same. The village in Togo where he lives with his wife and infant daughter relied on trade and travelers from nearby Benin. When the border closed after the first recorded infection that spring, prices of basic foodstuffs began climbing precipitously. The 31-year-old typically earned money tutoring, but then local schools…

Harvesting energy with space solar panels could power the Earth 24/7

Solar power has been a key part of humanity's clean energy repertoire. We spread masses of sunlight-harvesting panels on solar fields, and many people power their homes by decorating their roofs with the rectangles. But there's a caveat to this wonderful power source. Solar panels can't collect energy at night. To work at peak efficiency, they need as much sunlight as possible. So to maximize these sun catchers' performance, researchers are toying with a plan to send them to a place where the sun never sets: outer space. Theoretically, if a bunch of solar panels were blasted into orbit, they'd…

Gene linked to doubling risk of Covid-19 death found by UK scientists

British scientists have identified a gene that doubles the risk of dying from Covid-19, providing new insights into why some people are more susceptible to the disease than others, while opening up possibilities for targeted medicine. Around 60% of people with South Asian ancestry carry the high-risk gene, researchers at Oxford University said on Friday, adding the discovery partly explains the high number of deaths seen in some British communities, and the effect of Covid-19 in the Indian subcontinent. The scientists found that the increased risk is not because of a difference in genetic coding of the proteins, but because…

Pfizer says its antiviral pill slashes risk of severe Covid-19 by 89 percent

Pfizer Inc's experimental antiviral pill to treat Covid-19 cut by 89% the chance of hospitalization or death for adults at risk of severe disease, the company said on Friday, as its CEO vowed to make this promising new weapon in the fight against the pandemic available globally as quickly as possible.

Pfizer's pill, with the brand name Paxlovid, could secure U.S. regulatory approval…

5 things Mark Zuckerberg said about his plan for Metaverse that should make you very worried

On Thursday, at Facebook's developer conference, Mark Zuckerberg outlined his vision for the metaverse. Of course, the details were somewhat lost in the midst of his announcement that the company he founded in his Harvard dorm room waschanging its name from Facebook to Meta, in an attempt to better define its mission as it moves beyond its core social media apps. I definitely have thoughts about the idea that Facebook is changing its name, but those will have to wait. There is far a far more important thread to pull on, which is what Zuckerberg had to say about the…
