Decisions, decisions. All of us are constantly faced with conscious and unconscious choices. Not just about what to wear, what to eat or how to spend a weekend, but about which hand to use when picking up a pencil, or whether to shift our weight in a chair. To make even trivial decisions, our brains sift through a pile of "what ifs" and weigh the hypotheticals. Even for choices that seem automati
In modern law, battery is defined as intentional harmful or offensive contact with another person: If I punch or kick you, for example, that's clearly battery. But what about a company that contaminates the groundwater that ends up in your drinking glass? Some legal scholars argue that's battery, too.
More than a year after NASA's Mars InSight lander touched down in a pebble-filled crater on the Martian equator, the rusty red planet is now serving up its meteorological secrets: gravity waves, surface swirling "dust devils," and the steady, low rumble of infrasound, Cornell and other researchers have found.
