Why do certain plants flourish in some regions but not in others? A study led by researchers at the University of Göttingen sheds light on the factors that determine where plants grow and how these patterns have evolved over millions of years.
The team analyzed data from nearly 270,000 seed plant species.
A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.
Hackers are utilizing the WordPress mu-plugins (“Must-Use Plugins”) directory to stealthily run malicious code on every page while evading detection.
The technique was first observed by security researchers at Sucuri in February 2025, but adoption rates are on the rise, with threat actors now utilizing the folder to run three distinct types of malicious code.
“The fact that we’ve seen so many infections inside mu-plugins suggests that attackers are actively targeting this directory as a persistent foothold,” explains Sucuri’s security analyst Puja Srivastava.
Sam’s Club, an American warehouse supermarket chain owned by U.S. retail giant Walmart, is investigating claims of a Clop ransomware breach.

Three security bypasses have been discovered in Ubuntu Linux’s unprivileged user namespace restrictions, which could be enable a local attacker to exploit vulnerabilities in kernel components.
The issues allow local unprivileged users to create user namespaces with full administrative capabilities and impact Ubuntu versions 23.10, where unprivileged user namespaces restrictions are enabled, and 24.04 which has them active by default.
Linux user namespaces allow users to act as root inside an isolated sandbox (namespace) without having the same privileges on the host.
