Discovery of ray sperms' unique swimming motion and demonstration with bio-inspired robot

It is generally agreed that sperms 'swim' by beating or rotating their soft tails. However, a research team led by scientists from City University of Hong Kong (CityU) has discovered that ray sperms move by rotating both the tail and the head. The team further investigated the motion pattern and demonstrated it with a robot. Their study has expanded the knowledge on the microorganisms' motion and provided inspiration for robot engineering design.

Research establishes safe water thresholds for antimicrobials, to help mitigate resistance

The Exeter team's review summarizes and critically appraises the current approaches that study the concentrations of antimicrobials that increase AMR. By collating and assessing available data, they have recommended what these safe thresholds could be, to enable governments to act to reduce them.

New technology 'listens' for endangered right whales

E-Mail
One of the world's most endangered whale species could have added protection from threats posed by human marine activity, through technology developed by the University of East Anglia (UEA).
In partnership with the Scottish Association for Marine Science (SAMS) and the marine survey company Gardline Geosurvey Limited, UEA researchers have developed machine learning techniques that can be used to detect the presence of North Atlantic right whales by listening for the sounds they make underwater.
Detecting the animals' presence before they reach close proximity to large vessels or enter a mitigation zone can both protect animals and avoid costly shutdowns of offshore operations.

World's lakes losing oxygen rapidly as planet warms

TROY, N.Y. -- Oxygen levels in the world's temperate freshwater lakes are declining rapidly -- faster than in the oceans -- a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.
Research published today in
Nature found that oxygen levels in surveyed lakes across the temperate zone have declined 5.5% at the surface and 18.6% in deep waters since 1980. Meanwhile, in a large subset of mostly nutrient-polluted lakes, surface oxygen levels increased as water temperatures crossed a threshold favoring cyanobacteria, which can create toxins when they flourish in the form of harmful algal blooms.

Declining biodiversity in wild Amazon fisheries threatens human diet

A new study of dozens of wild fish species commonly consumed in the Peruvian Amazon says that people there could suffer major nutritional shortages if ongoing losses in fish biodiversity continue. Furthermore, the increasing use of aquaculture and other substitutes may not compensate.

Global Fishing Watch launches new technology to enhance ocean management

Global Fishing Watch has launched an innovative technology portal to help strengthen management of marine protected areas (MPAs) and other effective area-based conservation measures (OECMs). The portal hosts diverse datasets and analysis tools to support marine spatial planning and ocean stewardship. Founded by philanthropist and ocean advocate, Dona Bertarelli, the technology aims to revolutionize our ability to dynamically monitor and conserve marine ecosystems.

Fish adapt to ocean acidification by modifying gene expression

To survive in a reduced pH environment, marine organisms have to adjust their physiology which, at the molecular level, is achieved by modifying the expression of genes. The study of such changes in gene expression can aid in revealing the adaptive mechanisms of life under predicted future ocean acidification conditions.

"Scuba-diving" lizards use bubble attached to snout to breathe underwater

Semi-aquatic anoles live along neotropical streams and frequently dive for refuge, remaining underwater for up to 16 minutes. Lindsey Swierk, assistant research professor of biological sciences at Binghamton University, documented this behavior in a Costa Rican anole species in 2019. She had been shocked to see an anole submerge itself for such long periods and used a GoPro underwater to document the behavior.
"It's easy to imagine the advantage that these small, slow anoles gain by hiding from their predators underwater - they're really hard to spot!" says Swierk. "But the real question is how they're managing to stay underwater for so long."

Biodiversity devastation: Human-driven decline requires millions of years of recovery

A new study shows that the current rate of biodiversity decline in freshwater ecosystems outcompetes that at the end-Cretaceous extinction that killed the dinosaurs: damage now being done in decades to centuries may take millions of years to undo.
The current biodiversity crisis, often called the 6th mass extinction, is one of the critical challenges we face in the 21st century. Numerous species are threatened with extinction, mostly as a direct or indirect consequence of human impact. Habitat destruction, climate change, overexploitation, pollution and invasive species are among the main causes for Earth's biota to decline rapidly.
