Using NASA's Chandra X-ray spacecraft, astronomers from the University of Alabama in Huntsville have observed a merging galaxy cluster known as SPT-CLJ 2031-4037. They detected a rarely seen strong shock front in this galaxy cluster. The finding was.....»»
The universe"s biggest explosions made elements we are composed of, but there"s another mystery source out there
After its "birth" in the Big Bang, the universe consisted mainly of hydrogen and a few helium atoms. These are the lightest elements in the periodic table. More-or-less all elements heavier than helium were produced in the 13.8 billion years between.....»»

Deadly bird flu was detected in an egg-laying chicken flock in Iowa, affecting 4.2 million birds in the biggest U.S. outbreak since 2022......»»
The evolution of security metrics for NIST CSF 2.0
CISOs have long been spreadsheet aficionados, soaking up metrics and using them as KPIs for security progress. These metrics have traditionally measured specific systems or single indicators — vulnerabilities detected, percentage of vulnerabilities.....»»
Compromised courtroom recording software was served from vendor’s official site
Courtroom recording software JAVS Viewer has been saddled with loader malware and has been served from the developer’s site since at least April 2, a threat researcher has warned last month. After analyzing a flagged installer detected in a cus.....»»
CISOs pursuing AI readiness should start by updating the org’s email security policy
Over the past few years, traditional phishing messages — with their pervasive linguistic errors, thinly-veiled malicious payloads, and often outlandish pretexts — have been on the decline. Easily detected by most of today’s standard email secur.....»»
