To assist humans with household chores and other everyday manual tasks, robots should be able to effectively manipulate objects that vary in composition, shape and size. The manipulation skills of robots have improved significantly over the past few years, in part due to the development of increasingly sophisticated cameras and tactile sensors.

Researchers at Columbia University have developed a new system that simultaneously captures both visual and tactile information...

A Neptune-sized planet, TOI-3261 b, makes a scorchingly close orbit around its host star. Only the fourth object of its kind ever found, the planet could reveal clues as to how planets such as these form.

An international team of scientists used the NASA space telescope, TESS (the Transiting Exoplanet Survey Satellite), to discover the exoplanet, then made further observations with ground-based telescopes in Australia, Chile, and South Africa. The measurements placed the new planet squarely in the “hot Neptune desert”—a category of planets with so few members that their scarcity evokes a deserted landscape.

The team, led by astronomer Emma Nabbie of the University of Southern Queensland, pu...

If you’ve heard of two of the brain’s chemical neurotransmitters, it’s probably dopamine and serotonin. Never mind that glutamate and GABA do most of the work—it’s the thrill of dopamine as the “pleasure chemical” and serotonin as a tender mood-stabilizer that attract all the headlines.

Of course, the headlines mostly get it wrong. Dopamine’s role in shaping behavior goes way beyond simple concepts like “pleasure” or even “reward”...

Artificial intelligence (AI) is becoming increasingly useful for the prediction of emergency events such as heart attacks, natural disasters, and pipeline failures. This requires state-of-the-art technologies that can rapidly process data. In this regard, reservoir computing, specially designed for time-series data processing with low power consumption, is a promising option.

It can be implemented in various frameworks, among which physical reservoir computing (PRC) is the most popular...
