A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Antibiotic Sensitivity of Vibrio spp. and Shewanella algae Isolated From Brood and Egg of Mud Crab Hatchery

Animal Research and One Health, EarlyView.
Vibrio alginolyticus NBRC 15630, Vibrio parahaemolyticus ATCC 17802, Shewanella algae DW01, and Shewanella algae ATCC 51192 bacterial strains were found in the Mud crab brood and egg samples. All isolates were found to be sensitive to cefotaxime, chloramphenicol, gentamicin, and nitrofurantoin antibiotics.

Red Water and Brine Shrimps [PDF]

Nature, 1913
BY the kindness of Mr. A. W. Sheppard and Prof. A. Dendy, F.R.S., I have been enabled to examine specimens of the brine shrimps from Geelong mentioned by Mr. Whitteron in his letter (NATURE, June 12, p. 372). They belong to the species Parartemia zietziana, described by the late Mr. O. A. Sayce in 1903 (Proc. Roy. Soc. Victoria, xv., part ii., p. 232).

The endocannabinoid system regulates both ependymoglial and neuronal cell responses to a tail amputation in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background The endocannabinoid system is a neuromodulatory system implicated in cellular processes during both development and regeneration. The Mexican axolotl, one of only a few vertebrates capable of central nervous system regeneration, was used to examine the role of the endocannabinoid system in the regeneration of the tail and spinal ...
