Fish have been swallowing microplastics since the 1950s
Forget diamonds—plastic is forever. It takes decades, or even centuries, for plastic to break down, and nearly every piece of plastic ever made still exists in some form today. We've known for a while that big pieces of plastic can harm wildlife—.....»»
Car tires shed a quarter of all microplastics in the environment. Urgent action is needed
Every year, billions of vehicles worldwide shed an estimated 6 million tons of tire fragments. These tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our foo.....»»
Engineering DNA to mimic biological catch bonds with "fish-hook" system
In a first-of-its-kind breakthrough, a team of UBC Okanagan researchers has developed an artificial adhesion system that closely mimics natural biological interactions......»»
New maps show high-risk zones for whale-ship collisions—vessel speed limits and rerouting can reduce the toll
Imagine you are a blue whale swimming up the California coast, as you do every spring. You are searching for krill in the Santa Barbara Channel, a zone that teems with fish, kelp forests, seagrass beds and other undersea life, but also vibrates with.....»»
Earliest fish-trapping facility in Central America discovered in Maya lowlands
An archaeologist from the University of New Hampshire and her team have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland we.....»»
Ancient fish-trapping network supported the rise of Maya civilization
The Maya were landscape engineers on a grand scale, even when it came to fishing. On the eve of the rise of the Maya civilization, people living in what’s now Belize turned a wh.....»»
"Doomsday fish" washed ashore in California, but what does that mean?
If one oarfish landing on a beach is a sign of a disaster to come, how bad will it be if three wash up in quick succession?.....»»
Durable supramolecular plastic is fully ocean-degradable and doesn"t generate microplastics
Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) have developed a new durable plastic that won't pollute our oceans. The new material is as strong as conventional plastics and biodegradable, but what makes it spec.....»»
Reef studies highlight missing clues to conserve fish species
In Australia, shellfish reef restoration projects are helping to recover degraded coastal systems and enhance fish habitat, but much more research is needed to support and evaluate these efforts, researchers say......»»
Invasive zebra mussels are associated with elevated mercury levels in fish, study finds
A study found that invasive zebra mussels significantly alter aquatic ecosystems, and are associated with elevated mercury concentrations in fish. Mercury, a potent neurotoxin, poses a serious threat to both aquatic life and human health......»»
Scientists discover the molecular composition of potentially deadly venomous fish
New research in FEBS Open Bio reveals insights into the venom of two of the most venomous fish species on Earth: the estuarine stonefish (Synanceia horrida) and the reef stonefish (Synanceia verrucosa), which are typically found in the warm and shall.....»»
First ever goat-fish petroglyph reveals Egyptian understanding of zodiac symbols
A new study by Dr. Linda Evans and her colleagues from Macquarie University, Australia, published in the Journal of Egyptian Archaeology, has recently identified what may be an Egyptian petroglyph depicting the zodiac sign Capricornus, a hybrid creat.....»»
Latest edition of book offers guidance on monitoring and managing ranaviruses in amphibians, reptiles and fish
Researchers are providing new information and guidance on monitoring and managing viruses that cause life-threatening diseases in amphibians, reptiles and fish, as detailed in the second edition of Ranaviruses: Emerging Pathogens of Ectothermic Verte.....»»
World"s first visual grading system developed to combat microplastic fashion pollution
More than 14 million metric tons of microplastics are estimated to be lying on the ocean floor with the fashion industry among the worst pollutants......»»
Fish on film: Uncovering the environmental drivers of black spot syndrome
For many researchers in biology and other natural sciences, dissecting specimens may not be desirable, though it is often necessary. This is because dissection means killing the animal a researcher is trying to study—a big issue, especially if the.....»»
Simulations reveal black holes inherit magnetic fields from parent stars
Black holes are one of the most enigmatic stellar objects. While best known for swallowing up their surroundings into a gravity pit from which nothing can escape, they can also shoot off powerful jets of charged particles, leading to explosive bursts.....»»
In collective animal movements, speed matters—scientists use "force map" to investigate fish schools
Few things are as fascinating to look at a flock of starlings performing their aerial bird dance that is commonly seen, for example, above the West Pier in Brighton, UK, or in Rome when exiting the main train station, or a school of fish escaping a p.....»»
Mathematical model can help understand coexistence in nature
Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosyste.....»»
Troubled waters: How to stop Australia"s freshwater fish species from going extinct
Three-quarters of Australia's freshwater fish species are found nowhere else on the planet. This makes us the sole custodians of remarkable creatures such as the ornate rainbowfish, the ancient Australian lungfish and the magnificently named longnose.....»»
Decline in West African coastal fish stocks threatens food security and livelihoods
Small-scale fisheries play a vital role in providing food and livelihoods for millions of people around the world, particularly in low-income countries in Africa. However, there is limited statistical data on the composition, abundance, and distribut.....»»
