Teaching machine learning tools to detect specific objects in a specific image and discount others is a “game-changer” that could lead to advancements in cancer detection, according to leading researchers from the University of Surrey.
In Physics of Fluids, researchers develop a model to explore the forces and flow structures created by penguin wings underwater. Penguin can adjust swimming posture by active wing feathering, pitching, and flapping and their dense, short feathers can also lock air between the skin and water to reduce friction and turbulence. The hydrodynamic model takes in information about the flapping and feathering of the wings and, using the immersed boundary method, solves for the motion of the wing and the thrust, lift, and lateral forces.
If urban landfills disappear under the new European regulation, some endangered birds such as the Egyptian vulture will need alternatives to their feeding patterns in order to survive in the future.
Pseudo-nitzschia spp., an algae that produces the neurotoxin domoic acid, can bioaccumulate within food webs causing harm to humans and animals. A molecular study of Florida’s Indian River Lagoon shows this algae was present in 87 percent of the water samples collected. All isolates showed toxicity, and domoic acid was found in 47 percent of surface water samples. As a nursery for many organisms that supports a high amount of biodiversity, the presence of domoic acid could negatively impact the lagoon system.
As we enter the summer months in the Northern Hemisphere and the possibility of extreme heat becomes more common, it’s important to stay up-to-date on the science of heat waves and take measures to protect ourselves from this growing public health threat.
Although the prehistoric site of Eynan-Mallaha in northern Israel has been thoroughly examined since 1955, it still holds some surprises for scientists. Seven prehistoric wind instruments known as flutes, recently identified by a Franco-Israeli team.
Dreams have been considered a hallmark of human sleep for a long time. Latest findings, however, suggest that when pigeons sleep, they might experience visions of flight. Researchers at Ruhr University Bochum, Germany, and at the Max Planck Institute for Biological Intelligence studied brain activation patterns in sleeping pigeons, using functional magnetic resonance imaging.
Several animal species display brood care, a phenomenon where ‘caring’ parents provide their offspring with food and protection against predators.
Scientists at St. Jude Children’s Research Hospital have discovered H5N1 avian influenza viruses gained the ability to cause severe disease and target the brain in mammals as they spread across North America.
Oxytocin, the so-called “love hormone,” plays a key role in the process of how a young zebra finch learns to sing by imitating its elders, suggests a new study by neuroscientists at Emory University. Scientific Reports published the findings, which add to the understanding of the neurochemistry of social learning.
Current conservation practices likely won’t do enough to save the black tern, a migratory bird species that nests in the northern U.S. and southern Canada, from disappearing. That’s according to new research from Michigan State University and the National Audubon Society published in the journal Biological Conservation. But the team’s report also reveals new opportunities to enhance the outlook for these birds by strategically expanding conservation and land management practices. Furthermore, the team’s approach can help inform conservation practices for other species.
Birds across the Americas are getting smaller and longer-winged as the world warms, and the smallest-bodied species are changing the fastest.
A new WCS-led study that analyzed 17 years of migratory bird-nesting data in Prudhoe Bay, Alaska, revealed that nest survival decreased significantly near high-use oil and gas infrastructure and its related noise, dust, traffic, air pollution, and other disturbances.
Researchers conducted the first ever systematic and comprehensive study of Mountain Quail habitat associations and fire ecology in the Sierra Nevada.

In an effort to generate high-quality images based on text descriptions, a group of researchers in China built a generative adversarial network that incorporates data representing common-sense knowledge. Their method uses common sense to clarify the starting point for image generation and also uses common sense to enhance different specific features of the generated image at three different levels of resolution.
A panel of experts will hold a WCS media briefing on High Pathogenic Avian Influenza (HPAI) that is currently wreaking havoc around the world and is the largest known outbreak since scientists have begun tracking the disease.
Below are some of the latest headlines in the new Avian Flu channel on Newswise.
Many birds’ feathers are remarkably efficient at shedding water — so much so that “like water off a duck’s back” is a common expression.
Since the 1950s, humanity has produced an estimated 8.3bn tons of plastic, adding a further 380m tons to this amount each year. Only 9% of this gets recycled.
A new study demonstrates that birds can partially compensate for these changes by delaying the start of spring migration and completing the journey faster. But the strategy comes with a cost—a decline in overall survival.
Avian research often focuses on forests as breeding habitats, but scientists are now working to understand the vital role that small forest patches play in migration. For the first time, a team of researchers from Princeton University and the University of Delaware has created a comprehensive map of migratory pathways and stopover locations in the Eastern United States.
Every year, millions of birds crash into windows in cities along their migratory path.
As an ecological modeler and the director of BRI’s Quantitative Wildlife Ecology Research Lab, Evan spends much of his time considering innovative ways to analyze large datasets such as the 2023 Maine Bird Atlas, or working with offshore energy wind developers along the Atlantic coast.
A new study led by researchers at the University of Utah explores a record of birds’ diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds’ dietary options.
Montane forests, known as biodiversity hotspots, are among the ecosystems facing threats from climate change.
The 2023 Great Backyard Bird Count exceeded all expectations. Organizers estimate that more than 500,000 participants from around the globe made the latest count the best ever.
When exotic species such as parrots, snakes, monkeys, or aquarium fishes are kept as pets, this may lead to unsustainable trade and impact negatively the conservation of these species globally.
Spring has arrived officially and brings with it another season of the NestWatch citizen-science project from the Cornell Lab of Ornithology, building its ever more valuable database on nesting birds. NestWatch participants say watching birds raise their young is incredibly rewarding.
An eagle twice the size of the modern-day apex predator the wedge-tailed eagle, which soared over southern Australia more than 60,000 years ago, had a wingspan up to 3m wide and powerful talons wide enough to grab a small kangaroo or koala.
Researchers at Cummings School of Veterinary Medicine at Tufts University found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
Hummingbirds have the fastest metabolism of any animal. The tropical hummingbirds that live in the Andes Mountains in South America must expend considerable energy to maintain their high body temperatures in cold environments. One tool that they use to survive cold nights is called torpor, a hibernation-like state that allows them to ramp down energy consumption to well below what they normally use during the day.
A study of chicken farms in the West found that high winds increased the prevalence of Campylobacter in outdoor flocks, a bacterial pathogen in poultry that is the largest single cause of foodborne illness in the U.S.
Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this "win-win" relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.
The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs.
Exercising too much and not getting enough rest is bad for your health. A new study from Lund University in Sweden shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.
Much of the progress made in understanding the scope of bird deaths from building and window collisions has come as the result of citizen science, according to a newly published study. But the study also concludes that such grassroots efforts need more buy-in from government and industry, and better funding so they can keep a foot on the gas in their efforts to reduce bird-window collisions.
There are reasons to assume that not only humans but also some non-human species of animal have conscious perception.
Avian functional diversity patterns in the Western U.S., where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high, according to new research.
The mainly brown woodcock uses its bright white tail feathers to communicate in semi-darkness, reflecting 30% more light than any other known bird.
Researchers at the Max Planck Institute of Animal Behavior in Germany and Swansea University have revealed how different seabird species use distinct strategies to cope with cyclones, with some flying directly into the storm, and others using avoidance tactics.
