A new model explains the wrinkling patterns seen in nature’s donut-shaped objects, such as those found in jellyfish.

Summary: Synaptic pruning occurs as a result of mechanical tearing, a new study reveals.

Nerve cells communicate with one another via long processes known as axons and dendrites, or, more generally, neurites. During development, these processes first grow and form connections with other cells, for example synapses with other nerve cells. Any neurites which are not properly linked, or are no longer needed, are removed by a corrective mechanism known as “pruning”.
The WordPress online course plugin ‘LearnPress’ was vulnerable to multiple critical-severity flaws, including pre-auth SQL injection and local file inclusion.
LearnPress is a learning management system (LMS) plugin that allows WordPress websites to easily create and sell online courses, lessons, and quizzes, providing visitors with a friendly interface while requiring no coding knowledge from the website developer.
The vulnerabilities in the plugin, used in over 100,000 active sites, were discovered by PatchStack between November 30 and December 2, 2022, and reported to the software vendor.
