Dolphins Are Exhaling Microplastics
New research highlights how extensive plastic pollution is—and how nonhuman species, including dolphins, are exposed......»»
Microplastics are everywhere, but are they harming us?
Microplastics have been found in the ocean and the air, in our food and water. They have been found in a wide range of body tissues, including the heart, liver, kidneys and even testicles......»»
3D models show dolphins already used narrow-band sound waves for orientation 5 million years ago
Senckenberg researcher Dr. Rachel Racicot and her former student Joyce Sanks from Vanderbilt University have examined the inner ear of the extinct dolphin genus Parapontoporia. In their study, published in the journal The Anatomical Record, they show.....»»
Waters along Bar Harbor, Acadia, home to billions of microplastics
Along the shores of Acadia National Park, Bar Harbor and the Schoodic Peninsula are the vast, briny waters of Frenchman Bay. With 98 square miles of water and 39 islands, the bay is vital to shorebirds, fish, lobstermen and outdoor recreationists. Un.....»»
Elevated levels of antibiotic resistance genes should be considered a new factor of global change, researchers say
Human-caused global change is a complex phenomenon comprising many factors such as climate change, environmental contamination with chemicals, microplastics, light pollution, and invasive plants. One of the main tasks of global change biology is to i.....»»
Cape Cod"s fishhook topography makes it a global hotspot for mass strandings by dolphins
The recent stranding of more than 100 dolphins on Cape Cod, the largest such event involving dolphins in U.S. history, is partly due to the peninsula's geography, with its gently sloping sand flats, tidal fluctuations and proximity to productive feed.....»»
Q&A: "We lost instruments chewed or crunched by bears and sea otters"—how a researcher listens for elusive belugas
Dr. Manuel Castellote studies the behavior and conservation of whales and dolphins. After beginning his academic career in Spain, he now works in the United States, applying acoustic techniques to learn more about cetaceans—especially beluga whales.....»»
Our clothes generate microplastics that pollute the St. Lawrence River and other bodies of water, say researchers
Our clothes are made mainly of plastic......»»
Porous materials and machine learning provide inexpensive microplastic monitoring method
Optical analysis and machine learning techniques can now readily detect microplastics in marine and freshwater environments using inexpensive porous metal substrates. Details of the method, developed by researchers at Nagoya University with collabora.....»»
Are the Microplastics Found in Testicles a Health Danger?
Evidence shows microplastics can end up in many different organs and may harm reproductive health.....»»
Ambitious targets are needed to end ocean plastic pollution by 2100, analysis finds
A collaboration between researchers at Imperial College London and GNS Science, suggests that reducing plastic pollution by 5% per year would stabilize the level of microplastics—plastics less than 5 mm in length—in the surface oceans......»»
Many microplastics in the world"s oceans have likely escaped detection, researchers say
Chemicals within microplastics that are found in our world's oceans and waterways, and in drinking water sources, remain of concern to scientists and public health officials. A new study that investigated the presence of the smallest particles of mic.....»»
Are we really about to talk to whales?
The past decade has seen an explosion of new research into some of the most fascinating sounds in the sea: the vocalizations of whales and dolphins......»»
What are nanoplastics? An engineer explains concerns about particles too small to see
It's become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastic.....»»
"Everywhere we looked, we found evidence": Microplastics expert on 20 years of pollution research
Thirty years ago, while counting barnacles, limpets and seaweeds along rocky shores, I started noticing a daily tide of litter, mostly plastic. As a marine biology Ph.D. student at Liverpool University, I kept removing it, but the next day, there'd b.....»»
Citizen science project finds that respectful boat users are rewarded with magical dolphin encounters
A citizen science project reveals that most boat users along the North-East coast in the U.K. do not disturb dolphins and are often rewarded with close-up encounters......»»
Polystyrene microplastics shown to enhance invasion of exotic submerged macrophytes
Submerged macrophyte invasions and microplastic pollution are major challenges in the context of global change and pose a serious threat to aquatic environments. The presence of microplastics in aquatic ecosystems alters plant function, sediment micr.....»»
Plugging the leak on laundry pollution
Joaquim Goes, an ocean biochemist at Columbia Climate School's Lamont-Doherty Earth Observatory, had to look twice when he first saw the tiny strands of fiber floating in a water sample from the Hudson River. An expert in microplastics detection, he.....»»
Whales and dolphins now have legal personhood in the Pacific—but one treaty won"t be enough to protect them
Whales and dolphins have been officially recognized as "legal persons" in a new treaty formed by Pacific Indigenous leaders from the Cook Islands, French Polynesia, Aotearoa (New Zealand) and Tonga......»»
Low-density polyethylene microplastics partially alleviate toxicological effects induced by Cd exposure in earthworms
Cadmium (Cd) can accumulate in the food chain, with serious impacts on human health and safety. Microplastics (MPs) such as low density polyethylene (LDPE) should be considered not only as a single pollutant but also as a carrier of other pollutants......»»
Study finds microbes hitchhike on microplastics to reach the sea
The oceans contain large amounts of microplastics, particles that are less than 5 mm in size. In parts of the Baltic Sea, the concentration of microplastics can be as much as 3,300 particles per cubic meter. The microplastics end up in aquatic enviro.....»»
