1+ day, 14+ hour ago  (13+ words) Researchers investigate how quantum time flow can be stretched, blurred, or even reversed....

2+ day, 12+ hour ago  (23+ words) A machine learning-powered simulation is giving researchers a new window into the processes that create some of the universe's heaviest elements....

4+ day, 19+ hour ago  (633+ words) Harvard researchers found that adding a little randomness to robot movements can prevent gridlock and dramatically boost efficiency in crowded swarms. Imagine a swarm of robots sent into a tight space to handle an urgent job, such as cleaning up…...

4+ day, 19+ hour ago  (567+ words) A single transistor that behaves like a brain cell in the deep freeze could help unlock the next generation of quantum computers and space exploration systems. Researchers at the University of Hong Kong (HKU) have developed a new type of…...

5+ day, 27+ min ago  (643+ words) It may not be long before video game controllers become optional. The findings were published in Nature Neuroscience. Busch and her colleagues believed the problem stemmed from how these systems were designed. Often, BCIs required the brain to learn patterns…...

6+ day, 16+ hour ago  (375+ words) Researchers in Sweden have developed a machine-learning approach that embeds the laws of physics directly into neural networks. "When we fed the super-brain information about the laws of physics, it immediately got much smarter. Our calculations now take one tenth…...

6+ day, 16+ hour ago  (907+ words) Scientists have found a way to make GPS remarkably accurate in city "urban canyons," where navigation has long gone wrong. Most of us trust that the location shown by our GPS is accurate. But anyone who has tried navigating an…...

6+ day, 16+ hour ago  (478+ words) Bird flocks, bacterial swarms, and even crowds move according to interaction rules that appear to break one of physics" most fundamental principles: Newton"s law of action and reaction. Birds can see much of what is happening around them, but…...

1+ week, 1+ hour ago  (498+ words) One familiar example is a quantum bit, or qubit, which can exist as a combination of both 0 and 1. However, quantum systems are not restricted to two states. Quantum harmonic oscillators can occupy many energy levels, creating far more possibilities. These…...

1+ week, 11+ hour ago  (788+ words) A new satellite-based framework allows scientists to measure the changing rhythms of cities in near real time. Cities are often described as living systems, but until now that idea has mostly been a metaphor. Roads, buildings, parks, and neighborhoods change…...
