New artificial intelligence and space radar technology has uncovered scores of vessels hiding outside North Korea’s largest port, laying bare the sheer number of ships looking to cover their tracks in unprecedented detail.

The finding comes courtesy of Global Fishing Watch’s (GFW) synthetic aperture radar (SAR) data, which reveals hundreds of vessels, many of them cargo ships, outside of Nampho in recent weeks despite not broadcasting over traditional maritime channels.

While vessels entering North Korean waters often switch off their automatic identification system (AIS) transponders to avoid detection by sanctions monitors, open-source satellite.

Strange planets nicknamed BEASTies are unlikely to have formed around their current stars. They may have been stolen from other stars or captured from deep space.

Gargantuan young stars blast this region with ultraviolet radiation, and that may play a key role in how solar systems eventually form.

Y Combinator’s latest cohort of founders have opinions on the future of fintech. One-fifth of the accelerator’s Summer 2022 batch, which spans 240 companies, is working on solving issues in the financial space. The pitches range from building the Square for micro-merchants in Latin America to creating a way to angel invest in your favorite athlete.

And while the pitches are diverse, some concentrations show key ways that a group of vetted entrepreneurs are thinking about the landscape’s shift in light of finicky venture markets, a downturn, and some public market meltdowns. The most popular problem area among this batch’s fintech cohort has to do with payments, which is unsurprising. The story really begins with which focus made second place: neobanks.

Scientists have detected a sunspot that’s so huge it’s changing the way our sun vibrates.

Sunspots appear as dark blotches on the sun’s surface because they are cooler than the surrounding areas. They form where magnetic fields are particularly strong, driven by the electrically charged gases that constantly swirl inside our nearest star.

Sometimes these magnetic fields can be so intense that they prevent some heat from reaching the surface, forming a sunspot.

Metamaterials offer many properties normally not found in nature, from superior lenses and communications to stealth applications, potentially offering invisibility. Today we’ll examine the science behind that and look at many other possible applications.

For all of history, there’s been an underlying but unspoken assumption about the laws that govern the Universe: If you know enough information about a system, you can predict precisely how that system will behave in the future. The assumption is, in other words, deterministic. The classical equations of motion — Newton’s laws — are completely deterministic. The laws of gravity, both Newton’s and Einstein’s, are deterministic. Even Maxwell’s equations, governing electricity and magnetism, are 100% deterministic as well.

But that picture of the Universe got turned on its head with a series of discoveries that began in the late 1800s. Starting with radioactivity and radioactive decay, humanity slowly uncovered the quantum nature of reality, casting doubt on the idea that we live in a deterministic Universe. Predictively, many aspects of reality could only be discussed in a statistical fashion: where a set of probable outcomes could be presented, but which one would occur, and when, could not be precisely established. The hopes of avoiding the necessity of “quantum spookiness” was championed by many, including Einstein, with the most compelling alternative to determinism put forth by Louis de Broglie and David Bohm. Decades later, Bohmian mechanics was finally put to an experimental test, where it failed spectacularly. Here’s how the best alternative to the spooky nature of reality simply didn’t hold up.
