They call it stupid hot for a reason: Heat muddles animal brains
For animals such as fish and insects that can’t control their body temperature, heat waves could be particularly detrimental. “Changes in air temperature will affect brain temperature,” says Baird. A hotter brain could hinder the functioning of nerves, and that, she says, “might affect sensing, memory, and learning.” Cross section shows band of cells in

Grifters, cynics, and true believers: The family tree of vaccine opponents
Stanley Plotkin, 93, was instrumental in developing a number of vaccines over the course of his career. He recently said that he’s “beginning to regret having lived so long—because we’re going downhill.” How could we possibly have gotten here? Maybe we’ve always been here. It turns out that the anti-vaccine arguments currently flooding the Internet

Researchers develop a new process to get lithium out of rocks
The key chemical in the process is ammonium fluoride (NH4F). It’s possible to use the salt directly in a molten form, but heating it invariably leads to some production of hydrogen fluoride, which is extremely dangerous stuff (although they end up using some later). So instead, they used it dissolved in water, which apparently keeps

Forecasters predict below-average hurricane season, advise against complacency
Haiyan Jiang, a meteorologist at Florida International University, said there was a high chance of a strong El Niño that could boost water temperatures in the Gulf of Mexico. “We probably won’t have as many number of storms as previous years. However, some storms get lucky,” she said. “We see outliers all the time, especially

Want an oxygen-rich atmosphere? Stuff oxygen’s friends in the mantle.
The beginning of the story, they say, could be the assembly of an early “supercontinent” (think Pangaea) called Columbia. With an appreciable amount of land above sea level, erosion could deliver enough nutrients to the oceans to support a large amount of photosynthetic cyanobacteria. We can see the evidence of this in seafloor sedimentary rocks

China’s shark finning could lead to US seafood sanctions
Addressing allegations of worker abuse, the Chinese Embassy maintained that Beijing “attaches great importance to protecting the lawful rights and interests of workers and always asks Chinese companies to abide by laws and regulations.” Martínez said she wished the general public better understood these prehistoric animals. “Sharks fall under the class of fish, and because

Whatever the mirror test tells us, beluga whales pass it
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

SpaceX’s Starship V3—still a work in progress—mostly successful on first flight
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

Soaring solar and a surge in hydro push more coal off the US grid
Last year, the first few months of data from the US grid suggested that fears of a data-center-driven surge in demand were becoming a reality. Demand had risen by about 3 percent, triggering a surge in coal, interrupting what had been a long downward trend. But over the course of the year, both trends slowed

Ground system issue scrubs first launch of SpaceX’s Starship V3 rocket
SpaceX got within 40 seconds of launching the first flight of a taller, more powerful version of its Starship rocket Thursday, but a pesky problem with the launch tower kept the vehicle bound to Earth for at least one more day. Clouds and rain showers cleared the area around SpaceX’s launch site in South Texas,
