Are we living in a sixth mass extinction? Maybe not. But we might be able to define modern ecological crises by looking at fossil records and how rare species are today, according to researchers at Yale, Vanderbilt, and the Smithsonian Institution.
By recording the brain signals of one person in India with a computer system, converting them into electrical brain stimulations, and relaying them to recipients in France, one research team developed a noninvasive method of brain-to-brain communication.
Turning over is neither easy nor trivial for a belly-up tortoise — lying flipped over on its shell makes the reptile vulnerable to predation, among other hazards. According to a new study conducted at the University of Belgrade, certain types of tortoises may have an advantage in this situation depending on the geometry and size of their shells. In addition, researchers have investigated the evolutionary trade-offs of these ideal shell shapes.
