It’s time to make peace with one of the largest-known stars.

Everything is relative. By that, I mean: Jupiter, when compared to Earth, is large. Yet Jupiter, when compared to the Sun, is small. By virtue, the Sun in comparison with hypergiants is basically microscopic. Our local star actually sits right in the middle, between big and small, by star classification. There are many stars in our galaxy alone that fall on one end of the spectrum or the other. Yet, none has quite captured the imagination exactly like the “nearby” star known as VY Canis Majoris (otherwise known as HD 58,061 or HIP 35793) can.

Located approximately between 3,800 and 5,000 light-years from Earth in the constellation of Canis Major, VY Canis Majoris is technically classified as a red hypergiant, which means it is among the largest of stars known to exist in our galaxy. How large is it, you might ask? Well, VY Canis Major is estimated to be larger than between 1,800 and 2100 Suns, with between 15 to 25 times more mass. At its peak, it may be even weighed as much as 40 solar masses (one solar mass is equivalent to one of our suns, or 1.989 × 1,030 kg), but astronomers believe the star has moved beyond “main sequence” and is reaching the end of its stellar life span. Therefore, a significant amount of its mass has already been blown away by solar winds.

What if plants could tell us when pests are attacking them, or they’re too dry, or they need more fertilizer. One startup is gene engineering farm plants so they can communicate in in fluorescent colors. The result: a farmer’s phone, drone, or even satellite imagery can reveal what is happening in hundreds of acres of fields …

That leads to better food, fewer crop failures, and more revenue for farmers.

In this TechFirst with John Koetsier we meet Shely Aronov, CEO and founder at InnerPlant, and chat about what plants say, and how farmers can understand their messages.

Numbers like π, e and φ often turn up in unexpected places in science and mathematics. Pascal’s triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there’s the Riemann zeta function, a deceptively straightforward function that has perplexed mathematicians since the 19th century. The most famous quandary, the Riemann hypothesis, is perhaps the greatest unsolved question in mathematics, with the Clay Mathematics Institute offering a $1 million prize for a correct proof.

UC Santa Barbara physicist Grant Remmen believes he has a new approach for exploring the quirks of the function. He has found an analog that translates many of the function’s important properties into . This means that researchers can now leverage the tools from this field of physics to investigate the enigmatic and oddly ubiquitous zeta function. His work could even lead to a proof of the Riemann hypothesis. Remmen lays out his approach in the journalPhysical Review Letters.

“The Riemann zeta function is this famous and mysterious mathematical function that comes up in number theory all over the place,” said Remmen, a postdoctoral scholar at UCSB’s Kavli Institute for Theoretical Physics. “It’s been studied for over 150 years.”

Circa 2021


DETROIT – The EV Revolution is in full-swing right now. Tesla just passed the trillion-dollar valuation mark. Lucid Group just rolled out its first cars with 500+ miles of driving range. Rivian just had the biggest initial public offering since Facebook.

Every legacy automaker — from Ford to GM to Volkswagen — is investing tens of billions of dollars iino electrifying their fleets. The EV Revolution has arrived.

But here’s the thing: The EV Revolution won’t go mainstream until we make better batteries.

Parallel Systems bursts out of stealth mode with a SpaceX pedigree and a plan for launching the nation’s railways into the space age with autonomous electric railcars.


Electric trains have been much in the news lately. Adding to all the hoopla today is the US startup Parallel Systems, which has just busted out of stealth mode with a recipe for replacing thousands of trucks on the highways with zero emission short-haul autonomous electric railcars. The company sports a leading lineup of three former SpaceX electronics and battery experts, so let’s see what all the fuss is about.

Autonomous Electric Railcars

The idea of electric locomotives is beginning to catch on, but Parallel Systems is calling its version a “rail vehicle” because it has no resemblance to a locomotive. Think of it as a train without locomotives, and the picture comes into sharper focus.

“Your scientists were so preoccupied with whether they could, they didn’t stop to think if they should.” — Dr Ian Malcolm in Jurassic Park

Throughout most of human history, the goal was to establish a better life for people. Whether proponents of change admit to it or not, they hope to make everything perfect. However, this very impulse to improve security against everything bad and eliminate all physical ills could precipitate just another kind of doom.

To borrow the words of a Jeff Goldblum character, those of us who did the most to uplift humanity may have been “so preoccupied with whether they could, they didn’t stop to think if they should.”

In Carl Sagan’s The Demon-Haunted World, he pointed out that the modern world is complicated. Everything we don’t understand is something to fear (unless you are a specialist in it), and it is a thing that can be ignorantly speculated about in a vacuum, as vaccines are by many on social media.
