As demonstrated by breakthroughs in various fields of artificial intelligence (AI), such as image processing, smart health care, self-driving vehicles and smart cities, this is undoubtedly the golden period of deep learning. In the next decade or so, AI and computing systems will eventually be equipped with the ability to learn and think the way humans do—to process continuous flow of information and interact with the real world.

However, current AI models suffer from a per...

Webb Telescope Captures New Detail of Phantom Galaxy

The Phantom Galaxy is a "favorite target for astronomers studying the origin and structure of galactic spirals," NASA
The Phantom Galaxy is a “favorite target for astronomers studying the origin and structure of galactic spirals,” NASA and the ESA said.

The James Webb space telescope has revealed dazzling new detail of a previously known slice of the cosmos 32 million light-years away, in a new picture released by NASA and the European Space Agency (ESA).

The infrared technology of the telescope, launched in December 2021, has allowed for an even clearer view of the so-called Phantom Galaxy than astronomers had ever seen before.

“Webb’s sharp vision has revealed delicate filaments of gas and dust in the grandiose spiral arms which wind outwards from the center of this image,” NASA and the ESA said Monday.

“A lack of gas in the nuclear region also provides an unobscured view of the nuclear sta...

Researchers use Infrared Light to Wirelessly Transmit Power over 30 meters

Caption: Researchers created a new system that uses infrared light to safely transfer high levels of power over distances of up to 30 meters. This type of long-range optical wireless power transfer system could enable real-time power transmission to fixed and mobile receivers.

New laser charging system could offer safe cordless power for mobile devices and sensors. Imagine walking into an airport or grocery store and your smartphone automatically starts charging. This could be a reality one day, thanks to a new wireless laser charging system that overcomes some of the challenges that have hindered previous attempts to develop safe and convenient on-the-go charging systems.

“The ability to power devices wirelessly could eliminate the need to carry around power cables for our phones o...

ALMA witnesses deadly Star-slinging Tug-of-War between Merging Galaxies

While observing a newly-dormant galaxy using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope (HST), scientists discovered that it had stopped forming stars not because it had used up all of its gas but because most of its star-forming fuel had been thrown out of the system as it merged with another galaxy. The result is a first for ALMA scientists. What’s more, if proven common, the results could change the way scientists think about galaxy mergers and deaths. The results of the research are published in The Astrophysical Journal Letters.

As galaxies move through the Universe, they sometimes encounter other galaxies. As they interact, each galaxy’s gravity pulls on the other...
