MEXICO CITY (AP) — The youngest student ever admitted to Mexico's National Autonomous University wouldn't call himself a "genius." Carlos Santamaria Diaz, a 12-year-old who will begin classes for an undergraduate degree in biomedical physics Monday, was dwarfed by the upholstered blue chair he sat...

In this July 27, 2018 photo, Susan Hewitt photographs a daisy-like weed known as 'shaggy soldier' and adds it to iNaturalist, the app she uses to participate in the New York City EcoFlora project. "If people could just take a few minutes to look at nature closely, I think they would be blown away," Hewitt said. Hundreds of New Yorkers are working with researchers to find and catalog wild plants in their city. They’re taking pictures with their smartphones as they walk the streets. Participants have already found invasive species, plants never documented before in New York City, and endangered native weeds. (AP Photo/Emiliano Rodriguez Mega)

Whale researchers are keeping close watch on an endangered orca that has spent the past week carrying and keeping her dead calf afloat in Pacific Northwest waters. The display has struck an emotional chord around the world and highlighted the plight of the declining population of southern resident killer whales that has not seen a successful birth since 2015.(Michael Weiss/Center for Whale Research via AP)

This May 3, 2018 photo provided by Benjamin Bond-Lamberty shows a device measuring the amount of carbon dioxide released into the air from the soil at the Smithsonian Environmental Research Center near Edgewater, Md. Observations from across the globe show that as temperatures have warmed, bacteria and fungi in the soil are becoming more active. These turbo-charged microbes are feeding on dead leaves and plants, releasing more heat-trapping carbon dioxide into the air, according to a study in the Wednesday, Aug. 1, 2018 edition of the journal Nature.

WASHINGTON (AP) — Even the dirt on the ground is making climate change worse, a new study finds. Plants capture massive amounts of carbon, pumping it into the soil where usually it stays for hundreds or thousands of years. Observations from across the globe show that as temperatures have warmed,...

HONOLULU (AP) — Scientists are touting the first sighting of a hybrid between a melon-headed whale and a rough-toothed dolphin in the ocean off Hawaii. But don't call it a "wholphin," they say. The melon-headed whale is one of the various species that's called a whale but is technically a dolphin...

New research shows more promise for using AIDS treatment drugs, such as Truvada, as a prevention tool, to help keep uninfected people from catching HIV during sex with a partner who has the virus. Truvada has been shown to help prevent infection when one partner has the virus and one does not, but the evidence so far has been strongest for male-female couples. (AP Photo/Jeff Chiu, File)
