A new laboratory study shows these threats extend beyond direct physical or chemical impacts, revealing that the presence of microplastics increases the severity of an important viral fish disease.
The bacterium Rhodococcus ruber eats and actually digests plastic. This has been shown in laboratory experiments by PhD student Maaike Goudriaan at Royal Netherlands Institute for Sea Research (NIOZ).

Nearly 100 million years ago, the Earth experienced an extreme environmental disruption that choked oxygen from the oceans and led to elevated marine extinction levels that affected the entire globe.
A new study by Stony Brook University researchers published in the journal Global Change Biology demonstrates that warming waters and heat waves have contributed to the loss of an economically and culturally important fishery, the production of bay scallops.
A team of scientists from the National University of Singapore Tropical Marine Science Institute has developed a dolphin-inspired compact sonar with a novel echo processing method that allows for clearer visual imaging underwater compared to the conventional signal processing method of visualising sound echoes.
A rare three-dimensional fossil of an ancient chimaera has revealed new clues about the diversity of these creatures in the Carboniferous period, some 300 million years ago.
Fishes living in the twilight zone of the oceans reduce atmospheric carbon dioxide and are a huge food resource, but little is known about their response to climate warming. Geologist-Palaeontologist Konstantina Agiadi from the University of Vienna led a study funded by the Austrian Science Fund (FWF) that used fossils to answer this question. The results, published by the international team in the journal Proceedings of the Royal Society B: Biological Sciences, suggest that mesopelagic fishes overall shrink with warming.
New research finds that ice-sheet-wide collapse in West Antarctica isn’t inevitable: the pace of ice loss varies according to regional differences in atmosphere and ocean circulation.
New PNNL-developed nanogenerator harnesses the renewable energy in ocean waves to power sensors that provide critical weather and wave information.
The more-than 1.2 million km of fibre-optic cables that criss-cross the planet carry the world’s phone calls, internet signals and data.

Below are some of the latest articles that have been added to the Space and Astronomy channel on Newswise, a free source for journalists.
A new report and upcoming international virtual event addresses the unequal burden of marine plastics on different communities. The illustrated report includes case studies from around the world and recommends future changes.
The article shares lessons from SUNY Geneseo’s Marine Biology course and presents a model for bringing deep-sea research into undergraduate classrooms. Access to the deep oceans is limited to a select number of researchers, in large part due to the costs of ship time.
Researchers have discovered how short- and long-term climate trends have impacted Magellanic penguins — a migratory marine predator — over nearly four decades. Though individual events impacted penguins in a variety of ways, both were equally important for the future survival of this population.
Save the ... parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, researchers warn -- and that means not just fewer worms, but losses for the entire ecosystem.
In April to May 2019, the coral reefs near the French Polynesian island of Moorea in the central South Pacific Ocean suffered severe and prolonged thermal bleaching.
UC San Diego researchers suggest that rising levels of manmade chemicals, accumulating in marine plankton, might be used to monitor the impact of human activity on ecosystem health and perhaps study links between ocean pollution and land-based rates of childhood and adult chronic illnesses.
Mass coral bleaching events are making it harder for some species of reef fish to identify competitors, new research reveals.
Irvine, Calif., Jan. 4, 2023 — Climate-driven heating of seawater is causing a slowdown of deep circulation patterns in the Atlantic and Southern oceans, according to University of California, Irvine Earth system scientists, and if this process continues, the ocean’s ability to remove carbon dioxide from the atmosphere will be severely limited, further exacerbating global warming.
Researchers have created a map of oceanic “dead zones” that existed during the Pliocene epoch, when the Earth’s climate was two to three degrees warmer than it is now. The work could provide a glimpse into the locations and potential impacts of future low oxygen zones in a warmer Earth’s oceans.
Bladderwrack in the Baltic Sea emits significant amounts of methane, which, to some extent, can offset the uptake of atmospheric carbon dioxide by these algae.

The total amount of microplastics deposited on the bottom of oceans has tripled in the past two decades with a progression that corresponds to the type and volume of consumption of plastic products by society.
Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic.
Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration.
New research reveals that the animals that perceive time the fastest are those that are small, can fly, or are marine predators.
In the past, it was thought that with competition over food, lobsters would grow less. A new study from the University of Agder (UiA) shows the opposite.
