Month: July 2024

It was the last week in June, and José De Bardi hadn’t gotten much sleep. The trouble had really kicked off on June 18, about a week earlier, when the electric vehicle company Fisker announced it had filed for bankruptcy protection. Now some 6,400 Fisker owners like De Bardi wondered: What will happen to their cars in the future?

The bankruptcy “lit a fire,” De Bardi says. “We had to get organized if we had any chance of representing owners’ interests.” Within days, he and a handful of other Fisker vehicle owners had established a nonprofit organization called the Fisker Owners Association, dedicated to keeping their cars running. (Hence, the lack of sleep.) By the end of the month, 1,200 owners—representing nearly a fifth of total Fisker cars sold—had registered through the group’s website, De Bardi says.

One of the most promising Chinese space startups, Space Pioneer, experienced a serious anomaly this weekend while testing the first stage of its Tianlong-3 rocket near the city of Gongyi.

The rocket was undergoing a static fire test of the stage, in which a vehicle is clamped to a test stand while its engines are ignited, when the booster broke free. According to a statement from the company, the rocket was not sufficiently clamped down and blasted off from the test stand "due to a structural failure."

Video of the accidental ascent showed the rocket rising several hundred meters into the sky before it crashed explosively into a mountain 1.5 km away from the test site. (See various angles of the accident here, on the social media site X, or on Weibo.) The statement from Space Pioneer sought to downplay the incident, saying it had implemented safety measures before the test, and there were no casualties as a result of the accident. "The test site is far away from the urban area of ​​Gongyi," the company said.

Thus far, even AI companies have had trouble coming up with tools that can reliably detect when a piece of writing was generated using a large language model. Now, a group of researchers has established a novel method for estimating LLM usage across a large set of scientific writing by measuring which "excess words" started showing up much more frequently during the LLM era (i.e., 2023 and 2024). The results "suggest that at least 10% of 2024 abstracts were processed with LLMs," according to the researchers.

In a pre-print paper posted earlier this month, four researchers from Germany's University of Tubingen and Northwestern University said they were inspired by studies that measured the impact of the COVID-19 pandemic by looking at excess deaths compared to the recent past. By taking a similar look at "excess word usage" after LLM writing tools became widely available in late 2022, the researchers found that "the appearance of LLMs led to an abrupt increase in the frequency of certain style words" that was "unprecedented in both quality and quantity."

Delving in

To measure these vocabulary changes, the researchers analyzed 14 million paper abstracts published on PubMed between 2010 and 2024, tracking the relative frequency of each word as it appeared across each year. They then compared the expected frequency of those words (based on the pre-2023 trendline) to the actual frequency of those words in abstracts from 2023 and 2024, when LLMs were in widespread use.
