Attention readers, if you are using Google Chrome browser on your Windows, Mac, or Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today.

Google released Chrome version 86.0.4240.111 today to patch several security high-severity issues, including a zero-day vulnerability that has been exploited in the wild by attackers to hijack targeted computers.

Tracked as CVE-2020–15999, the actively exploited vulnerability is a type of memory-corruption flaw called heap buffer overflow in Freetype, a popular open source software development library for rendering fonts that comes packaged with Chrome.

It’s all coming together.

SpaceX is deploying a megaconstellation of internet-beaming Starlink satellites to provide internet service to rural areas around Earth where service is unreliable and not available. The Starlink network could provide SpaceX with additional funding to develop a fleet of Starships to colonize Mars.

The company already launched approximately 888 Starlink satellites to low Earth orbit out of over 4,000 that will be part of the broadband network. Starlink customers will receive low-latency, high-speed broadband service from the satellites via a dish user terminal and Wi-Fi router device.

“Whenever we have developed better clocks, we’ve learned something new about the world,” said Alexander Smith, an assistant professor of physics at Saint Anselm College and adjunct assistant professor at Dartmouth College, who led the research as a junior fellow in Dartmouth’s Society of Fellows. “Quantum time dilation is a consequence of both quantum mechanics and Einstein’s relativity, and thus offers a new possibility to test fundamental physics at their intersection.”

A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, Saint Anselm College and Santa Clara University.

Research describing the effect shows that superposition — the ability of an atom to exist in more than one state at the same time — leads to a correction in atomic clocks known as “quantum time dilation.”

The research, published today (October 23, 2020) in the journal Nature Communications, takes into account quantum effects beyond Albert Einstein’s theory of relativity to make a new prediction about the nature of time.

See ya later 👋! The nest was the first discovered in the U.S.

Crews with the WSDA Pest Program vacuumed the hornets from the tree cavity into large canisters Saturday. The nest was about the size of a basketball and contained an estimated 100 to 200 hornets.

The specimens will be used for research purposes, said Sven Spichiger, an entomologist with WSDA, during a press conference Friday afternoon.

Many people say that overpopulation will spell the end of humanity. However, with mind uploading and the consumption of fewer resources that comes with it, I believe that humanity will not have to worry about an overpopulation issue for decades to come.

If you own a perfectly fine conventional automobile but want to join the EV revolution, you have two choices. Engineer an electric drivetrain swap yourself, which involves hours and hours of lying on you back on a creeper in your garage, or buying a new electric car. Now, if you live in France, there’s a third way. Transition One will take your current car, remove the existing internal combustion engine, replace it with batteries and an electric motor, and give it back to you in about 4 hours.

Albert Einstein’s twin paradox is one of the most famous thought experiments in physics. It postulates that if you send one of two twins on a return trip to a star at near light speed, they will be younger than their identical sibling when they return home. The age difference is a consequence of something called time dilation, which is described by Einstein’s special theory of relativity: the faster you travel, the slower time appears to pass.

But what if we introduce quantum theory into the problem? Physicists Alexander Smith of Saint Anselm College and Dartmouth College and Mehdi Ahmadi of Santa Clara University tackle this idea in a study published today in the journal Nature Communications. The scientists imagine measuring a quantum atomic clock experiencing two different times while it is placed in superposition—a quirk of quantum mechanics in which something appears to exist in two places at once. “We know from Einstein’s special theory of relativity that when a clock moves relative to another clock, the time shown on it slows down,” Smith says. “But quantum mechanics allows you to start thinking about what happens if this clock were to move in a superposition of two different speeds.”

Physicists describe a way to merge quantum theory with Einstein’s special theory of relativity—and even a method to test it experimentally.
