Quantum engineers improved the silicon chip performance by 100 times setting a new standard

Posted by in categories: computing, quantum physics

Their quantum computing processors can store information up to two milliseconds.

Researchers from the University of New South Wales have broken new ground in quantum computing by demonstrating that ‘spin qubits’- qubits where the information is stored in the spin momentum of an electron-can store data for up to two milliseconds, 100 times longer than previous benchmarks in the same quantum processor.

Classical computers work with bits—consisting of ones and zeroes—but a quantum computer uses quantum bits or qubits, which, on top of the ones and zeroes, also has a superposition where it can be a one and a zero at the same time.

550-million-year-old Fossils Just Solved a Centuries-Old ‘Skeleton’ Mystery

Posted by in category: futurism

Determining the appearance of the earliest creatures to develop skeletons was impossible — until now.

Scientists have resolved a centuries-old mystery by determining the appearance of the earliest animals to create skeletons — thanks to an extremely well-preserved collection of fossils found in eastern Yunnan Province, China.

“This really is a one-in-million discovery”

This breakthrough AI can detect lung diseases with 98% accuracy

Posted by in categories: biotech/medical, robotics/AI

Researchers at the University of West Scotland (UWS) believe that groundbreaking artificial intelligence (AI) could help reduce winter stresses and demands on hospitals. The innovative approach, using AI, would automatically diagnose lung diseases, such as pneumonia and tuberculosis.

The research was published in the journal Computer Methods and Programs in Biomedicine.

In a world-first, an electric-powered plane was charged

Posted by in categories: engineering, sustainability, transportation

It took two electric trucks to cover a distance of 250 miles.

Remy Oktay, a US engineering student, has successfully completed a test run and is preparing to launch the world’s first electric flight that an electric vehicle will power.

Therefore the EV plane will need to be recharged three times.

Overcoming the optical resolution limit

Posted by in category: futurism

😀


When measuring with light, the lateral extent of the structures that can be resolved by an optical imaging system is fundamentally diffraction limited. Overcoming this limitation is a topic of great interest in recent research, and several approaches have been published in this area.

In a recent study published in the Journal of Optical Microsystems, a team of researchers from the University of Kassel in Germany present an approach that uses microspheres placed directly on the surface of the object to extend the limits of interferometric topography measurements for optical of small structures.

A Black Hole’s Jets are Coming From a Region 2,000 km Away From the Singularity Itself

Posted by in categories: cosmology, singularity

In 1961 astronomers discovered a powerful x-ray source coming from the constellation Cygnus. Not knowing what it was, they named the source Cygnus X-1. It’s one of the strongest x-ray sources in the sky, and we now know it is powered by a stellar-mass black hole. Since it is only about 7,000 light-years away, it also gives astronomers an excellent view of how stellar-mass black holes behave. Even after six decades of study, it continues to teach us a few things, as a recent study in Science shows.

Cygnus X-1 is actually a binary system. The black hole itself is a 21 solar-mass stellar remnant, and it orbits a 41 solar-mass companion star. It’s a powerful x-ray source because material from the star is captured into an accretion disk of the black hole, which superheats the material and generates jets of plasma that flow away from the black hole. This is a common situation for black holes, but astronomers still don’t understand all the details of how this type of structure evolves.

For this study, the team used data from the Imaging X-Ray Polarimetry Explorer (IXPE), which can capture not just x-rays but also their polarization. When they combined this data with other observations of Cygnus X-1, they found the x-rays are emitted not from the regions along the jets, but from a 2,000 km region perpendicular to the jets. In other words, the accretion disk itself is the primary x-ray source. This supports the model where the innermost region of the accretion disk is what powers a black hole’s jets.
