In hours of underwater video footage from a New York aquarium, a beluga whale named Natasha stretches her neck, pirouettes, nods, and shakes her head in front of a two-way mirror. Her daughter Maris does much the same. According to a new study published in PLOS One , both animals show the behavioral hallmarks of mirror self-recognition—a cognitive ability long considered a marker of self-awareness, and one that had never before been documented in beluga whales.

If the result holds up, belugas join a remarkably short list. The mirror self-recognition test (MSR) has been passed, with varying degrees of confidence, by humans (starting around age two), a handful of great apes (chimps, bonobos, orangutans, and—somewhat contentiously—gorillas), Asian elephants , bottlenose dolphins , probably magpies , possibly orcas , and, if you can believe it, a cleaner wrasse . That's it. No dogs, no cats, no monkeys. Plenty of species we had assumed were self-aware have been tested and failed.

Looking at the mirror

So what is this test, exactly, and what is it supposed to tell us?

SpaceX launched the first test flight of its upgraded Starship rocket and Super Heavy booster Friday, with mostly positive results.

The powerful rocket, propelled by 33 methane-fueled main engines, climbed away from SpaceX's Starbase launch facility in South Texas at 5:30 pm CDT (6:30 pm EDT; 22:30 UTC) Friday. Within a few seconds, the 408-foot-tall (124-meter) rocket, the largest ever built, cleared the launch tower and turned onto an eastward heading over the Gulf of Mexico.

Starship splashed down on target in the Indian Ocean a little more than an hour later to conclude the first flight of the latest version of SpaceX's stainless steel mega-rocket. Starship V3 fared better on its debut than the first flights of Starship V1 and V2 in 2023 and 2025 . Both past versions of Starship broke apart during launch on their inaugural flights.

Tom Akers and Joe Tanner are finally in the same class.

The two veteran space shuttle crew members were inducted into the US Astronaut Hall of Fame together on May 16. They could also have been in the same NASA astronaut selection group, too, had history played out a little differently.

In 1984, Tanner reported to the Johnson Space Center (JSC) to fly as an instructor pilot and then applied for the next class of astronaut candidates.

For migrant workers trapped onboard Chinese distant water fishing fleets, cutting the fins off sharks as they writhe violently on rusted decks in the Indian Ocean isn’t accidental. It’s an intentional and lucrative act that marks the start of a bloody half-a-billion-dollar offshore supply chain, tacitly supported by Beijing yet covertly concealed from port inspectors globally.

The Center for Biological Diversity, a nonprofit focused on the protection of endangered species, filed a formal petition this month requesting the U.S. government potentially sanction China for failing to meet American shark conservation standards. Shark populations have declined by more than 70 percent since 1970, with more than one-third of all shark and ray species now threatened with extinction. Yet each year, Chinese-flagged vessels catch, brutally fin, and discard thousands.

Should the National Marine Fisheries Service identify China as having violated the US Moratorium Protection Act, then President Trump could be expected to ban the import of all $1.5 billion of Chinese seafood.

At least four Russian military satellites changed their orbits to match that of a Finnish-American radar surveillance satellite in the last week, raising questions about Russia's intentions amid an ever-expanding standoff high above Earth.

The maneuvers were identified through open source orbital tracking data. Greg Gillinger, a retired Air Force space intelligence officer, revealed the orbit changes Friday in a special edition of his Integrity Flash newsletter , published by Integrity ISR, a private business that provides "combat-proven operational support and elite training that enhances mission success across ISR (Intelligence, Surveillance, and Reconnaissance), cyber, space, and targeting domains."

The Russian satellites in question, designated Kosmos 2610 through 2613, launched together on April 16 on a Soyuz-2.1b rocket from Plesetsk Cosmodrome in northern Russia. Over the last week or so, the four satellites adjusted their inclinations—the angles of their orbits to the equator—by less than a degree.

The Ebola outbreak erupting from the Ituri province of the Democratic Republic of the Congo continues to escalate wildly, with cases nearing 750, deaths reported at 177, and around 1,400 contacts now being traced, the World Health Organization reported in a press briefing Friday. The latest numbers already place the outbreak as the third largest on record, though it was only first reported a week ago, on May 15. And WHO Director-General Tedros Adhanom Ghebreyesus said the outbreak is still "spreading rapidly."

A revised WHO assessment has moved the risk level from "high" to "very high" at the national level, while risk remains "high" at the regional level and "low" at the global level, Tedros added.

WHO officials have acknowledged that a delay in detecting and responding to the outbreak enabled it to balloon, and that they are now racing to get ahead of the virus.

Google’s first Chromecast was a hit. With 10 million units sold in 2014, it excelled as an easy solution for streaming TV and movies from the Internet to a TV. Released at a time when dumb TVs were more common, the first-generation Chromecast has a simplicity you don’t find in streaming devices these days. Press "Cast" in an app, select a TV with a Chromecast, and start watching. Foregoing extras like a UI or ads, the device remains active in some homes today, despite Google ending support for the $35 device in 2023.

However, this week it seemed like those days were over. Numerous people reported that their original Chromecast had suddenly stopped casting from popular apps, including Chrome, YouTube, and Paramount+. This brought concern that the original Chromecast was really dead now . A Reddit thread started by someone who claimed to have two first-gen Chromecasts suddenly stop working at the same time includes various responses from people who suspected that Google bricked the devices in order to force upgrades.

But Sahana Mysore, senior product manager for Google Home, told Ars Technica today that Google didn’t kill the devices, saying:

The Federal Communications Commission is escalating its attack on ABC’s The View with a proceeding that seeks public comment on whether the talk show is a "bona fide news interview program."

The FCC Media Bureau today issued a public notice seeking opinions on whether The View qualifies for the bona fide news exemption to the equal-time rule, which requires equal time for opposing political candidates on non-news programming. The probe of The View is driven by Chairman Brendan Carr, who has embraced President Trump's declaration that the FCC is no longer an independent agency and used his chairmanship to open investigations into broadcasters that Trump dislikes.

"Decades ago, Congress made the decision to prevent covered broadcast television programs from being used to advance certain partisan political purposes," the Media Bureau public notice said. The equal-time rule exists to prevent broadcast television stations "from unfairly putting their thumbs on the scale for one political candidate or set of candidates over another," and "to ensure that no legally qualified candidate for office is unfairly given less access to the public airwaves than their opponent," it said.

Pilots’ voices from the last seconds of a fatal cargo plane crash have been re-created by Internet sleuths using software and AI tools. The spread of reconstructed audio recordings has prompted a US government agency to suspend all public access to its database of civil transportation accidents—because federal law prohibits investigators from publicly releasing audio from cockpit voice recorders.

The US National Transportation Safety Board (NTSB) usually shares factual reports and evidence gathered from investigations of aircraft crashes and other civil transportation incidents. But on May 21, the NTSB announced that the online docket system containing such information was “temporarily unavailable” as it reviewed the publicly available materials that had enabled people to re-create cockpit audio recordings from aircraft disasters.

“​​The NTSB is aware that advances in image recognition and computational methods have enabled individuals to reconstruct approximations of cockpit voice recorder audio from sound spectrum imagery released as part of NTSB investigations, including the ongoing investigation of the crash last year of UPS flight 2976 in Louisville, Kentucky,” according to an NTSB statement . “The NTSB does not release cockpit audio recordings.”
