Using cryogenic electron microscopy, a research team from the Research Center for Artificial Photosynthesis (ReCAP) at Osaka Metropolitan University has revealed, for the first time, the structures and binding environments of pigments bound to a protein called a photosynthetic antenna of the marine green macroalga Codium fragile. The team’s results extend our knowledge about the molecular mechanism by which blue-green light—the only light available in deep seawater—is efficiently utilized for photosynthesis.

An international team of researchers respond to criticisms on previous work that demonstrated Mirror Self-Recognition (MSR) in the cleaner fish Labroides dimidiatus, by 1) successfully repeating the mark test with a larger sample size, 2) showing the MSR behaviour to be the visual result of the mark not a physical response to it, and 3) showing that MSR-trained fish do not show aggression to spatially varied mirror images of themselves. Additionally, they further demonstrate potential self-awareness in L. dimidiatus by showing that they do not demonstrate MSR behaviour when visually presented with the mark on other fish and solidify the importance of ecologically relevant marks presented in previous work by showing MSR behaviour of L. dimidiatus with brown marks, meant to resemble a main food source of the fish, as opposed to no such behaviour in fish with green or blue marks.

Coral reefs, comprising some of the most diverse and delicate ecosystems under water, are under immense stress. From global warming to pollution to pathogens, many of the reef-building coral species are listed as threatened or endangered. But, according to researchers in Japan, the corals may have an unlikely ally: bacteria.

Through a series of prosocial choice tasks, researchers reveal prosocial and antisocial characteristics in male convict cichlid fish. The fish distinguish between female breeding partners, unknown females, and rival males by adjusting their actions to either provide food for both them and the females or avoid providing food for the rival males.

Giants in history
The techniques that make industrial pearl culturing possible were developed over a century ago at the Misaki Marine Biological Station in Japan. The station’s first director, Professor Kakichi Mitsukuri, emphasized to Kokichi Mikimoto in 1890 that stimulating pearl sac formation was important for pearl growth, and they went on to successfully develop methods for culturing pearls.
Osamu Shimomura (27 August 1928 – 19 October 2018) was a Japanese organic chemist and marine biologist who dedicated his career to understanding how organisms emitted light.
Edgardo Dizon Gomez (7 November 1938 – 1 December 2019) was a Filipino marine biologist who recognized the need to protect marine resources, especially coral reefs, in the Philippines.
