For people with high blood pressure, a new study shows that an individual’s circadian rhythm may be a key factor in when they should take their medication. In other words, night owls may benefit from taking the medicine at night, early birds in the morning. Science Alert has more: https://flip.it/A4NIf1

As if the decision to withdraw life support for patients with traumatic brain injuries weren't excruciating enough, a small modeling study suggests that it has at times been withdrawn too early. The American College of Surgeons recommends full ICU treatment for at least 72 hours. But there are no guidelines in the U.S. as to which patients should be taken off life support and when.

Martian meteorites are turning out to be quite an asset. These tiny bits of rock were chipped off of Mars, flung into space, and eventually landed on Earth about 11 million years ago. Today they’re giving scientists new insight into the fine structure of the outer later of the red planet. Science Alert explains: https://flip.it/Lb8hDb

Panama’s government recently presented keys to the new houses it was providing for about 300 families from a small island in the San Blas Archipelago. What spurred the kind gesture? Increasing floods and damage from storms caused by climate change. The Atlantic shares more in this photo feature that spotlights the country’s relocation efforts for Indigenous communities threatened by a rising sea and staggering lack of space. https://flip.it/3vegLI

AI chatbots and large language models struggle to convey genuine empathy, a new study found, but that’s not the worst of it. Research led by a Stanford computer scientist shows that these conversation agents can also encourage toxic belief systems like Nazism, racism, and sexism.

On the lunar surface, a single Earth day would be 56 microseconds shorter — a tiny number that can lead to significant inconsistencies over time. That’s why scientists aren’t just looking to create a new “time zone” for the Moon, but an entirely new “time scale” that accounts for the faster speed at which seconds tick by up there.

It's firefly season at Congaree National Park in South Carolina, and a lucky few won the park lottery this year — an opportunity to see thousands of fireflies, blinking in synchrony, for a few short weeks this spring.

NPR reports: "According to the National Park Service, there are just three types of fireflies in North America that are synchronous, meaning they coordinate their belly lanterns to flash at exactly the same time."

How did scientists calculate the speed of a supermassive black hole? Much in the same way crash-scene investigators can determine the speed of a car on impact. This cosmic predator gobbled up a star and left only its “wobbling” remains after imposing a grisly death. Live Science explains: https://flip.it/AkUicp
