The new study, published in Global Environmental Change, found that both Europeans and Australians were highly concerned about the human health impact of marine plastic pollution, ranking it top of 16 marine-related threats in terms of cause for concern, including chemical or oil spills, marine biodiversity loss and climate change related effects such as sea-level rise and ocean acidification.
Clownfish are instantly recognizable by their white stripes, which appear as they mature from larvae into adults. But how these distinctive patterns form has long remained a mystery. Now, a new study has found that the speed at which these white bars form depends on the species of sea anemone in which the clownfish live. The scientists also discovered that thyroid hormones, which play a key role in metamorphosis, drive how quickly their stripes appear.
Patients at high risk for cardiovascular events who had the highest levels of eicosapentaenoic acid (EPA) in their blood one year after taking daily omega-3 carboxylic acid, a prescription-grade fish oil, had similar rates of major cardiovascular events as people taking a corn oil placebo, according to a secondary analysis of the STRENGTH trial presented at the American College of Cardiology's 70th Annual Scientific Session.
A team of researchers led by Loretta Roberson of the Marine Biological Laboratory, Woods Hole, has installed the first seaweed farm in Puerto Rico and U.S. tropical waters. The research array furthers the design and development of a system for offshore cultivation of tropical seaweeds to support large-scale production of biomass for biofuels and other valuable bioproducts.
Microplastics do not just end up in the open sea - in fact, a lot also end up in the ecosystems of the coastal zones, a new study shows and this may threaten wildlife.
E-Mail 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.
E-Mail 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.

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.

Symes 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.
