Phys.org / Rainfall can shape bird populations as much as temperature, global study reveals

Scientists have long focused on rising temperatures to understand how climate change is reshaping the natural world. But there's a critical blind spot in that picture: rain. A new global study reveals precipitation has been ...

Phys.org / Ancient zircon crystals provide a window into early Earth history

There are many open questions about how our planet formed 4.55 billion years ago: When did plate tectonics start? When did the Earth's mantle begin to vigorously circulate in a process called convection? What was Earth like ...

Phys.org / Liquid crystal phase in antiferromagnets can be detected electrically

The best candidate for next-generation magnetic devices—technology that can power, store, sense or transport information—may be, counterintuitively, antiferromagnets. Today, the most widely used magnetic materials are ...

Phys.org / Rewilding could fill gap left by Panama's lost giants

Many large herbivores that once roamed modern-day Panama have declined or died out—including the 6-meter-long giant ground sloth and elephant-related creatures called Cuvieronius. New research suggests that introducing ...
