Welcome to Startups Weekly, a nuanced take on this week’s startup news and trends by Senior Reporter and Equity co-host Natasha Mascarenhas. To get this in your inbox, subscribe here. It’s been a big week for tech acronyms. I woke up on Monday to news that First Republic Bank has been closed down by regulators — and JP Morgan will buy $330 billion worth of assets. The news then spiraled into another question for startups: How does losing yet another banking partner, in a matter of weeks, feel in this environment? As…

We have detected a strange new signal from across the chasm of time and space.A repeating fast radio burst source detected last year was recorded spitting out a whopping 1,863 bursts over 82 hours, amid a total of 91 hours of observation.This hyperactive behavior has allowed scientists to characterize not just the galaxy that hosts the source and its distance from us, but also what the source is.The object, named FRB 20201124A, was detected with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China…

Astronomers have detected a strange and persistent radio signal from a far-off galaxy that appears to be flashing with surprising regularity, similar to a 'heartbeat'.The signal is classified as a fast radio burst, or FRB -- an intensely strong burst of radio waves of unknown astrophysical origin, that typically lasts for a few milliseconds at most.However, this new signal, labelled FRB 20191221A, persisted for up to three seconds -- about 1,000 times longer than the average FRB.Within this window, the team, including…

The detection of a new and strange fast radio burst originating from a galaxy located 3 billion light-years away has left astronomers puzzled. Fast Radio Burst or FRB are bursts of radio waves in space that are milliseconds long. Usually, these radio bursts occur and don't repeat. However, in the latest observation, the radio burst was found to be repetitive. An object named FRB 190520 was detected by astronomers when it released a burst of radio waves on May 20, 2019.It was located using the Five-hundred-metre Aperture…

A newly discovered source of repeating fast radio bursts has deepened the mystery of what, precisely, could be producing these powerful outbursts.The source, first detected in 2019 and named FRB 190520B, seems to be frequently spitting out millisecond bursts of powerful radio waves.  This has allowed astronomers to perform analyses that reveal information about where it comes from in the Universe, and the space around it. Those analyses suggest that there is probably more than one mechanism in the big wide cosmos capable…
