Survey any office, and you’ll see pens tapping, heels bouncing and hair being twiddled. But jittery humans aren’t alone. Mice also fidget while they work. What’s more, this seemingly useless motion has a profound and widespread effect on mice’s brain activity, neuroscientist Anne Churchland of Cold Spring Harbor Laboratory in New York and colleagues report September 24 in Nature Neuroscience. Scientists don’t yet know what this brain activity means, but one possibility is that body motion may actually shape thinking. Researchers trained some mice to lick a spout corresponding to an area where a click or a flash of light originated. To start their task, mice grabbed a handle and waited for the signal. As the mice focused on their jobs, researchers used several different methods to eavesdrop on nerve cell behavior in the animals’ brains. All the while, video cameras and a sensor embedded on a platform under the mice picked up every move the rodents … [Read more...] about Mice fidget. Those motions have big effects on their brains

Three spouted vessels from graves in ancient European cemeteries may have come from the mouths of babes. Chemical signs of nonhuman animal milk in the artifacts suggest that the small clay containers, previously found in three children’s graves in southeastern Germany, represent early versions of baby bottles, researchers report. Spouts on these types of pots would have delivered milk to babies and young children during weaning, biomolecular archaeologist Julie Dunne of the University of Bristol in England and colleagues conclude September 25 in Nature. Two of the graves where the newly analyzed vessels were found date to between around 2,800 and 2,450 years ago. The third burial dates to between about 3,200 and 2,800 years ago. Two of the youngsters died at around age 1 or 2; the other might have been as old as 6. Similar clay vessels with spouts, some of which are shaped as animals, date to as early as 7,500 years ago in Europe. Such finds have been recovered at early farming … [Read more...] about Baby bottles may go back millennia in Europe

A leaked paper suggests that Google has achieved a milestone known as quantum supremacy, using a quantum computer to perform a calculation that couldn’t be achieved even with the world’s most powerful supercomputers. It’s a hotly anticipated goal, and one intended to mark the beginning of a new era of quantum computation (SN: 6/29/17). But it’s also largely symbolic: The calculation in question serves no practical purpose and is designed to be difficult for classical computers, standard computers that are not rooted in quantum physics. On September 20, the Financial Times reported that a scientific paper, briefly published on a NASA website before being removed, claims that Google has built a quantum computer that achieved quantum supremacy. It’s a benchmark that the company’s quantum researchers, led by physicist John Martinis of the University of California, Santa Barbara, have set their sights on for years (SN: 3/5/18). An apparent plain-text … [Read more...] about Rumors hint that Google has accomplished quantum supremacy
