THE NEMATOCYST TOXIN OF METRIDIUM

open access: yesThe Biological Bulletin, 1971
1. Material discharged by isolated nematocysts of Metridium senile senile Linnaeus (1767) has been found to be toxic to crayfish Orconectes virilis Hagen (1870), O. propinquus Girard (1852), and Procambarus econfinae Hobbs (1942).2. The toxin appears to be composed of a proteinaceous, undialyzable fraction, and a dialyzable fraction containing two ...

Techniques and Advances in Ultrafast Photography

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
