An international group of scientific experts co-directed by CNRS oceanographer Jean-Pierre Gattuso has stated the requirements for coral reef survival in an article published in
Biological Conservation. Over 500 million people rely on coral reefs for the protection they confer against submersion, the fishing resources they offer, and the tourism they help attract. Yet these ecosystems are among the most threatened by global warming: since the 1980s, there has been a rise in the number of bleaching episodes, during which corals expel the microscopic algae that keep them alive. While these events are reversible if the temperature change is only brief, prolonged bleaching can kill corals and the ecosystems associated with them.

DURHAM, N.H. An international development team, led by researchers at the University of New Hampshire, has released a user-friendly software program they created that can process sound data collected from the world s oceans in a more standardized format that will enhance research and collaboration and help understand the global sea soundscape dynamics, including the impact of COVID-19 when travel and economic slowdowns put a halt to human activities in the ocean. Soundscape analysis can be important in detecting and interpreting changes in ocean ecosystems, said Jennifer Miksis-Olds, research professor and director of UNH s Center for Acoustics Research and Education. Sound is the dominant sensory mode for marine life and humans for sensing the underwater environment, so understanding how the background ocean sound levels are changing will provide insight into how sensory systems (both biological and electronic) are impacted.
POSTECH professor Hyung Joon Cha s research team develops a drug-delivering adhesive patch that mimics the blood vessel formation mechanism.
The patch can be applied to any shape anyplace and was verified for the regenerations of myocardial infarction and severe skin loss.

Researchers from Kumamoto University (Japan) have found that adult nocturnal fishflies (
Neochauliodes amamioshimanus), which are typically aquatic insects, feed on pollen at night. They also present circumstantial evidence suggesting that this species not only forages in flowers, but is also a supplementary pollinator. Their work sheds light on the terrestrial life of adult fishflies, which has been a mystery until now.

A new publication from the Dauphin Island Sea Lab s Marine Mammal Research Program (DISL) examines how bridge-building and in-water construction activities may affect manatees and other large aquatic species. The article, which was recently published in
The Journal of Wildlife Management, addresses the direct causes of injury and death and the longer-term, cumulative impacts on manatees and their habitats.
Some issues associated with construction activity include possible entanglement in barriers such as booms and siltation screens, loss of important habitats such as seagrass beds, and increased vessel activity near construction sites.
