The Zwicky Transient Facility recently announced the detection of an optical transient AT2020blt at redshift $z=2.9$, consistent with the afterglow of a gamma-ray burst. No prompt emission was observed. We analyse AT2020blt with detailed models, showing the data are best explained as the afterglow of an on-axis long gamma-ray burst, ruling out other hypotheses such as a cocoon and a low-Lorentz factor jet. We search \textit{Fermi} data for prompt emission, setting deeper upper limits on the prompt emission than in the original detection paper. Together with \konus{} observations, we show that the gamma-ray efficiency of AT2020blt is $\lesssim 2.8\%$, lower than $98.4\%$ of observed gamma-ray bursts. We speculate that AT2020blt and AT2021any belong to the low-efficiency tail of long gamma-ray burst distributions that are beginning to be readily observed due to the capabilities of new observatories like the Zwicky Transient Facility.

Chinese and Russian vessels have for the first time jointly traversed the Tsugaru Strait in between Honshu and Hokkaido islands.

A record-breaking result reveals the precision achievable by atomic clocks, letting researchers detect slightly faster ticking over a tiny height change.

Based on a rolling five-year average of announced investments, AlixPartners expects companies to invest $330 billion in the next five years throughout the EV supply chain globally. About a third of that is expected to be for batteries, largely in the China and Europe, while the U.S. attempts to catch up.

That forecast is up by 65% from an expected $200 billion from 2,018 according to Kumar.

“Electrification is occurring faster than many were thinking even a few years ago,” he said. “The plans OEMs have in place have started to change dramatically.”

Russia’s Deputy Minister of Foreign Affairs doesn’t exclude replacing the U.S. dollar in the country’s international reserves with “some digital assets.”
