Toshiba Europe and global telecommunications corporation Orange say they have achieved a significant advance in securing network communications from ever-more powerful computer attacks.

Security experts have been warning that a new generation of quantum computers is likely only a few years away from attaining the ability to crack today’s stringent public key encryption codes.

Some experts say quantum computers will be strong enough to crack the widely adopted RSA-2048 encryption standard for secure online transactions within about 15 years. The Cloud Security Alliance had a more dire—and precise—prediction: Encryption safeguards will be overtaken by April 14, 2030...

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the protoplanetary disk around a young star have discovered the most compelling chemical evidence to date of the formation of protoplanets. The discovery will provide astronomers with an alternate method for detecting and characterizing protoplanets when direct observations or imaging are not possible. The results will be published in an upcoming edition of The Astrophysical Journal Letters.

HD 169142 is a young star located in the constellation Sagittarius that is of significant interest to astronomers due to the presence of its large, dust- and gas-rich circumstellar disk that is viewed nearly face-on...

It could be the shopping trip that saves your life: supermarket trolleys are helping to diagnose atrial fibrillation which can then be treated to prevent disabling or fatal strokes. The research is presented today at ACNAP 2023, a scientific congress of the European Society of Cardiology (ESC).

“This study shows the potential of taking health checks to the masses without disrupting daily routines,” said study author Professor Ian Jones of Liverpool John Moores University, UK. “Over the course of two months, we identified 39 patients who were unaware that they had atrial fibrillation...

The first stars of the universe were very different than the stars we see today. They were made purely of hydrogen and helium, without heavier elements to help them generate energy in their core. As a result, they were likely hundreds of times more massive than the sun. But some of the first stars may have been even stranger. In the early universe, dark matter could have been more concentrated than it is now, and it may have powered strange stellar objects known as dark stars.

Since dark matter and regular matter act similarly under gravity, clumps of dark matter in the early universe could have gathered clouds of hydrogen and helium around them. As this matter collapsed under its own weight, dark matter in its core might have generated energy...
