Scientists have detected the heaviest and youngest infant star ever discovered close to the black hole at the center of our Galaxy. They also identified the region where this ‘impossible star’ may have formed.

An international team of researchers under the leadership of Dr Florian Peißker at the University of Cologne’s Institute of Astrophysics has discovered a very young star in its formation phase near the supermassive black hole Sagittarius A* (Sgr A) at the centre of our Milky Way...

Inflammatory diseases like rheumatoid arthritis have complex disease mechanisms that can differ from patient to patient with the same diagnosis. This means that currently available drugs have little effect on many patients. Using so-called digital twins, researchers at Karolinska Institutet have now obtained a deeper understanding of the “off and on” proteins that control these diseases...

Cybercriminals are coming up with increasingly savvy ways to disrupt online services, access sensitive data or crash internet user’s devices. A cyberattack that has become very common over the past decades is the so-called Distributed Denial of Service (DDoS) attack.

This type of attack involves a series of devices connected to the internet, which are collectively referred to as a “botnet.” This “group” of connected devices is then used to flood a target server or website with “fake” traffic, disrupting its operation and making it inaccessible to legitimate users.

To protect their website or servers from DDoS attacks, businesses and other users commonly use firewalls, anti-malware software or conventional intrusion detection syste...

The James Webb Space Telescope has spotted six massive galaxies that emerged not long after the Big Bang, a study said Wednesday, surprising scientists by forming at a speed that contradicts our current understanding of the universe.

Since becoming operational last July, the Webb telescope has been peering farther than ever before into the universe’s distant reaches—which also means it is looking back in time.

For its latest discovery, the telescope spied galaxies from between 500 to 700 years million years after the Big Bang 13.8 billion years ago, meaning the universe was under five percent of its current age.

Webb’s NIRCam instrument, which operates in the near infrared wavelength invis...
