I’ll admit that I didn’t see this one coming: Retraction Watch is reporting that the Cambridge Crystallographic Data Center (CCDC), the world’s main repository of small-molecule crystal data, is on the way to pulling nearly a thousand deposited crystal structures because they appear to have been faked. A preprint from earlier this year from David Bimler flagged what seems to be a paper-mill operation flooding out bogus papers on metal-organic frameworks: hundreds and hundreds of weirdly worded manuscripts on nonexistent MOFs and their imaginary applications, full of apparently randomly selected “references” to the rest of the literature. And these things depositited crystal data with the CCDC, which is the step that I really didn’t expect.

After all, anyone who studies the scientific literature has (especially in recent years) seen these auto-generated papers full of crap. But faked crystal structure files? That’s nasty. The record of these papers shows a sudden jump in 2020 and 2021, leading Bimler to wonder:

The dates paint a picture of accelerating publication, as if a small-scale cottage industry had been scaled up to a production line with a larger staff. One can imagine crystallographers initially ghostwriting manuscripts as a favour for friends, moonlighting from their day job, and becoming progressively more professional, though this must remain speculation.

When producer Irwin Allen’s popular television series Voyage to the Bottom of the Sea debuted its second season on ABC in September, 1965, viewers would note some exciting changes and additions to the show. Voyage was now broadcast in color, the nuclear submarine Seaview had been modified into a sleeker, four-windowed look, and the show would feature an important new star: the Flying Sub, a vehicle that flies through the air at incredible speeds and submerges to travel underwater at great depths.

The Flying Sub (also referred to as the FS-1) quickly became a signature element of the show, featured in almost every episode not only as a quick transport from the Seaview to land, but as an underwater exploration and defense vehicle that could dock at underwater research laboratories or on other submarines, and do battle with the menagerie of undersea monsters that threatened the Seaview. With its upswept, manta ray-like shape, vivid yellow-and-blue paint scheme, twin stabilizer fins, upper and lower hatches, gleaming headlights and the large forward windows that allowed viewers to actually see Admiral Nelson and Captain Crane (or at least miniature figures of them) at the controls of the craft, the Flying Sub became one of the most familiar and unique sights on ABC television in the 1960s, adding action and excitement to a TV show already overflowing with visual wonders.

Motors are ubiquitous in our everyday lives — from cars to washing machines, even if we rarely notice them. A futuristic scientific field is working on the development tiny motors that could power a network of nanomachines and replace some of the power sources we currently use in electronic devices.

Researchers from the Cockrell School of Engineering at The University of Texas at Austin created the first ever solid-state optical nanomotor. All previous iterations of these light-driven motors reside in a solution of some sort, which limited their potential for the majority of real-world applications. This new research was published recently in the journal ACS Nano.

The vehicles we’ll see on the roads in a decade’s time will be radically different from what we have at present. Design language will change a lot, as hinted by the concepts and prototypes put together by big names and budding automotive designers.

The focus definitely will be on personal mobility in the most sustainable manner possible. Compact vehicles that will trade off the greatest of luxuries for a more sensible method of commuting will be the norm. This boomerang-shaped two-seater vehicle with multiple use-case scenarios is different from what we’ve seen so far. Even in the automotive landscape dominated by some really bizarre vehicle concepts.

China search engine giant Baidu Inc said on Monday it has obtained permits to operate fully driverless robotaxi services on open roads from two Chinese cities, the first of their kind in the country.

FINHAUT, Switzerland — Switzerland is adding a much needed cog in the wheel to its energy supply with an underground hydropower plant that says it has capacity to store enough electricity to charge 400,000 car batteries simultaneously.

Developers of the 2.2 billion Swiss franc ($2.30 billion) Nant de Drance plant in the canton of Valais, which came online in July, say the facility operates like a giant battery.

Its six turbines tucked in a cavern 600 metres below ground between the Emosson and Vieux Emosson reservoirs have capacity of 900 MW, making it one of the most powerful pumped storage plants in Europe.

“Hello, we’ve been trying to reach you about your car’s extended warranty.” After years of seemingly unstoppable scam robocalls, this phrase is embedded into the minds of many of us. Last month the Federal Communications Commission (FCC) announced it was ordering phone providers to block any calls coming from a known car warranty robocall scam, offering hope that U.S. phone users may hear that all-too-familiar automated voice a little less often.

But there is more work required to crack down on these calls. After all, car warranty warnings are only one type of scam. To understand how robocallers reach us, and why it’s so hard to stop them, Scientific American spoke with Adam Doupé, a cybersecurity expert at Arizona State University.
