Microplastics found embedded in tissues of whales and dolphins
Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student's study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics ca.....»»
New cobalt complex triggers ferroptosis in cancer cells
In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to eliminate damaged cells or to control the number of cells in certain tissues, for exam.....»»
New technology offers a better look at tardigrade fossils embedded in amber
A trio of evolutionary biologists at Harvard University's Museum of Comparative Zoology has learned more about the evolutionary history of tardigrades by studying two fossils embedded in amber. In their study, published in Communications Biology, Mar.....»»
A new mechanism for shaping animal tissues
A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams from the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden, Germany, the Exce.....»»
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......»»
A Band-Aid for the heart? New 3D printing method makes this, and much more, possible
In the quest to develop life-like materials to replace and repair human body parts, scientists face a formidable challenge: Real tissues are often both strong and stretchable and vary in shape and size......»»
Scientists using new sound tech to save animals from extinction
Research, conducted by The University of Warwick and the University of New South Wales in Australia, analyzes animal sounds from endangered species including types of elephants, whales and birds......»»
Cycode unveils Cycode AI to enhance ASPM platform with advanced security features
Cycode has unveiled Cycode AI, a suite of AI-powered features that are now embedded in the company’s Complete ASPM platform. This integration empowers security teams and developers to increase productivity, accelerate velocity, and gain visibility.....»»
A new model to study regeneration of brown adipose tissues
The prevalence of obesity worldwide has led to an increase in the risk of metabolic diseases and socio-economical burdens. Brown adipose tissue (BAT) has been established as a promising therapeutic target to overcome obesity, type 2 diabetes (T2D) an.....»»
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.....»»
Nanoscopic imaging aids in understanding protein, tissue preservation in ancient bones
A pilot study from North Carolina State University shows that nanoscopic 3D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determ.....»»
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.....»»
Baleen plates provide new insight on life history of blue and fin whales
Researchers have recently released a study in Ecology and Evolution outlining their in-depth analysis of historic baleen plates, the comb structures that are used by some species of whales to filter food, from Southern Hemisphere blue and fin whales......»»
Enzyme-powered "snot bots" help deliver drugs in sticky situations
Snot might not be the first place you'd expect nanobots to be swimming around. But this slimy secretion exists in more places than just your nose and piles of dirty tissues—it also lines and helps protect the lungs, stomach, intestines and eyes. An.....»»
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.....»»
World"s rarest whale may have washed up on New Zealand beach, possibly shedding clues on species
Spade-toothed whales are the world's rarest, with no live sightings ever recorded. No one knows how many there are, what they eat, or even where they live in the vast expanse of the southern Pacific Ocean. However, scientists in New Zealand may have.....»»
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.....»»
Research finds humpbacks were happier during pandemic pause
University of Queensland-led research has found migrating humpback whales off Australia's east coast became less stressed over the first year of the COVID-19 pandemic. The research paper is published in Marine Environmental Research......»»
Our clothes generate microplastics that pollute the St. Lawrence River and other bodies of water, say researchers
Our clothes are made mainly of plastic......»»
