A rare severe geomagnetic storm watch is issued for the first time in nearly 20 years amid "unusual" solar event.

CBS News quotes the U.S. National Oceanic and Atmospheric Administration (NOAA): "Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth's surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations."

Jonathan An, an assistant professor of oral sciences, tries to ignore the hype around new life-extension treatments. But while studying for his doctorate in dentistry, An experimented with a drug normally used for organ transplant rejection on mice with oral disease. It worked, and An plans to test the drug on humans next. We may not live forever, but could science help us enjoy the time we have? Read more from Vox: https://flip.it/i0-9ZS

Several companies are offering people in mourning a chance to chat with a “simulation” of a deceased loved one. Some say it feels like they’re speaking to them from beyond the grave, while others find it disconcerting and manipulative. Ethicists Tomasz Hollanek and Katarzyna Nowaczyk-Basińska from the University of Cambridge are the latest to voice their concerns over the risks of the "digital afterlife industry."

When Hunga Tonga-Hunga Ha’apai erupted in January 2022, the underwater volcano in the South Pacific unleashed the most intense lightning storm ever recorded and set off a mega-tsunami that was hundreds of feet high. Research indicated the eruption was fueled by two merging magma chambers. Now, scientists are looking at another potential trigger. Live Science has more: https://flip.it/ZAjd2N

Venus wasn’t always hot and uninhabitable. Scientists think the second planet from the sun could have had as much water as Earth billions of years ago, and may have even supported life if any of that water was in liquid form. But researchers have a new theory as to how our neighbor in the solar system lost nearly all of its water and why it may have happened far faster than initially thought. The Conversation has more on the study.

Scientists have identified a genetic form of Alzheimer’s disease in older people, pinpointing a gene of which some people carry two copies. The gene, called APOE4, is not only a risk factor but an underlying cause for the disease when found twice in a person’s DNA, researchers say. Finding a way to target APOE4 in treatment is crucial because Leqembi, the only drug found to slow the disease, causes dangerous side effects in people with the gene. The Associated Press has more.

After trillions of periodical cicadas emerged from years of burrowing in the U.S. last month, scientists are hoping to capitalize on the rare event by studying the effects the insects have on the food chain. Brood XIII and Brood XIX are loudly buzzing across America together for the first time since 1803, making 2024 a year of plentiful food for for snakes, spiders, birds, and even some mammals. But what happens when this all-you-can-eat buffet doesn’t come back next year? The BBC has more.

When Rakus, an orangutan at the Suaq Project in Medan, Indonesia, had a nasty wound below his right eye, the animal knew exactly what to do. Scientists observed Rakus pluck and chew up leaves of a medicinal plant, then use his fingers to apply it to the injured area. Within a month, the wound had closed.
