Researchers at Facebook AI develop a new reinforcement learning algorithm named DD-PPO. It can navigate through complex environments using only compass data, RGB-D camera, and GPS. Developing intelligent machines that interact smartly with the...
Scientists break the world record for the fastest spinning object. The new object revolves at 300 billion revolutions per minute. It is made of a dumbbell-shaped silica nanoparticle powered by lasers. Torque sensors enabled the first...
Researchers find evidence of the second exoplanet orbiting our nearest stellar neighbor Proxima Centauri. Dubbed Proxima c, it may be six times as massive as Earth. It is estimated to be much colder than Earth and unlikely to be habitable. For...
Researchers discover a new type of T-Cell Receptor (TCR) that identifies and destroys most human cancer types, without affecting healthy cells. It increases the prospect of “one-size-fits-all” cancer treatment. The traditional method of...
The space-based quantum internet would substantially outperform ground-based networks of quantum repeaters. Building a global-scale quantum internet would require placing more than 400 satellites at an altitude of 1,900 miles. The most useful...
Although Alexander Graham Bell is generally credited for inventing the telephone, it was the culmination of research done by many individuals. Antonio Meucci, Johann Philipp Reis, Innocenzo Manzetti, and Elisha Gray made important contributions...
The new machine learning tool predicts how long a given computer chip takes to execute specific code. It is more accurate than Intel’s own prediction model. Determining the number of clock cycles a processor takes to execute a block of...
Astronomers have found a star cluster that shouldn’t exist. It lies 94,000 light-years away from Earth and is only 120 million years old. Because of Magellanic Clouds, these stars managed to form in very unsuitable surroundings. Like...
According to the Copernicus Climate Change Service, 2019 was the second warmest year ever recorded. Global atmospheric carbon dioxide concentrations increased by 2.3 ± 0.8 ppm in 2019. Understanding past atmospheric and climate change helps us...
Researchers observe how pyrocumulonimbus clouds form by a rising thermal from a fire. They studied wildfires that occurred in the Pacific Northwest in August 2017. Up to 50% of the ozone layer depleted over some parts of Canada. Wildfire is...
