| Bronze Age: how the market began Posted: 29 Jun 2021 04:17 PM PDT Knowing the weight of a commodity provides a way to value goods in the marketplace. But did a self-regulating market even exist in the Bronze Age? And what can weight systems tell us? Researchers investigated the dissemination of weight systems throughout Western Eurasia. Their simulation indicates that the interaction of merchants, even without intervention from institutions, is likely to explain the spread of Bronze Age technology to weigh goods. |
| Fungi embrace fundamental economic theory as they engage in trading Posted: 29 Jun 2021 01:13 PM PDT When you think about trade and market relationships, you might think about brokers yelling at each other on the floor of a stock exchange on Wall Street. But it seems one of the basic functions of a free market is quietly practiced by fungi. |
| A new piece of the quantum computing puzzle Posted: 29 Jun 2021 11:43 AM PDT Scientists have developed a groundbreaking quantum logic gate that brings quantum computing closer to reality. |
| Speedy nanorobots could someday clean up soil and water, deliver drugs Posted: 29 Jun 2021 11:43 AM PDT Researchers have discovered that minuscule, self-propelled particles called 'nanoswimmers' can escape from mazes as much as 20 times faster than other, passive particles, paving the way for their use in everything from industrial clean-ups to medication delivery. |
| Computer training program for seniors can reduce hazardous driving Posted: 29 Jun 2021 10:43 AM PDT A recent proof-of-concept study finds that a low-cost training program can reduce hazardous driving in older adults. Researchers hope the finding will lead to the training becoming more widely available. |
| Stretching changes the electronic properties of graphene Posted: 29 Jun 2021 09:07 AM PDT The electronic properties of graphene can be specifically modified by stretching the material evenly, say researchers. These results open the door to the development of new types of electronic components. |
| 'Edge of chaos' opens pathway to artificial intelligence discoveries Posted: 29 Jun 2021 07:11 AM PDT Some neuroscience theories suggest the human brain operates best 'at the edge of chaos'. Now scientists have found that keeping a nanowire network at the edge of becoming chaotic is the best state for it to produce useful signals to solve problems. |
| AI learns to predict human behavior from videos Posted: 28 Jun 2021 08:37 AM PDT A new study unveils a computer vision technique for giving machines a more intuitive sense for what will happen next by leveraging higher-level associations between people, animals, and objects. |
