Research shows nighttime drops in oxygen force fish to use more energy and could affect the health of entire reef ecosystems Abu Dhabi, UAE: A new study from NYU Abu Dhabi has found that small coral reef fish in the Arabian Gulf are facing a hidden but growing source of stress. When oxygen levels drop at night, a common occurrence on some of the world’s hottest reefs, these fish must use extra energy just to recover the next day. Over time, this additional strain could impact their growth, survival, and the overall balance of reef ecosystems. The research shows that even short nighttime drops in oxygen force the Gulf blenny, ...

Key points The COVID-19 pandemic had an immediate effect on how educators at museums and science centers interacted with their audiences. Many began offering online programming for the first time while simultaneously grappling with budget shortfalls, staff layoffs and low morale. Two inquiry-based studies had previously tracked the application of distance learning in museums. In a third study, recently published in the Quarterly Review of Distance Education, researchers assess the state of online museum programming three years after the pandemic’s onset to find out what worked ...

Beaver dams are critical to river health and a source of biodiversity. They create wetlands, slow water and improve water quality. They also reduce flood peaks and delay runoff. But beaver dams are often blamed when extreme rainstorms cause flooding — especially when they fail. This blame had serious consequences following the extraordinary rainstorms that hit Quebec’s Charlevoix region in 2005 and 2011 in the wake of Hurricanes Katrina and Irene. Flooding along the Port-au-Persil watershed caused considerable damage to a riverside inn downstream, leading its owners to successfully sue the Charlevoix-Est Regional County ...

Simon Fraser University researchers have uncovered concerning fibreglass contamination in a key estuary on Vancouver Island, raising concerns about how an as-yet overlooked contaminant could affect aquatic birds, marine life and coastal communities that rely on shellfish and seafood. A new SFU study found fibreglass particles buried in the sediment and biofilm layers of the Cowichan Estuary, a 400-hectare intertidal ecosystem used by the Cowichan Tribes First Nations for generations. The areas is an internationally designated important bird area ...

A new study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family). In “Who’s coming home? Shorter early-life telomeres predict return to the natal colony in an Arctic seabird” authors Jingqi Corey Liu, Olivier Chastel, Christophe Barbraud, Claus Bech, Pierre Blévin, Paco Bustamante, Børge Moe, Elin Noreen, and Frédéric Angelier found that kittiwake chicks with shorter telomeres were more likely to return to their birthplace as adults, contradicting predictions that longer telomeres would indicate better ...

Biologists have long wondered why caribou are the only deer in the world in which females, like males, have antlers. A study of shed antlers collected from calving grounds in the Arctic National Wildlife Refuge provides a new answer. Calving grounds are areas where migratory females give birth every year and also where they shed their antlers. Researchers at the University of Cincinnati found evidence that caribou, particularly moms with newborns, gnaw on antlers that were shed years earlier to supplement their diets with crucial minerals. The study ...

A new study sheds light on the behavior of yeast cells in the gut, paving the way for new lines of yeast that more efficiently produce therapeutic drugs tailored to address specific diseases. “Yeast is promising as a drug-delivery platform,” says Nathan Crook, corresponding author of the study and an associate professor of chemical and biomolecular engineering at North Carolina State University. “Previous work has shown that yeast cells can be modified to produce specific molecules in the gut, such as therapeutics that ...

Key takeaways Precious transition metals like platinum and palladium are used as catalysts to speed up chemical reactions that produce carbon-nitrogen bonds. UCLA organic chemists have figured out how to make inexpensive phosphine act like a transition-metal catalyst by using a light-reactive molecule to activate it. The achievement could be useful in the pharmaceutical industry and help bring down the price of some drugs. A discovery by UCLA organic chemists may one day put catalytic converter thieves out of business. In new research, they’ve used ...

Global efforts to combat climate change in the last two decades have contributed to considerably cutting carbon emissions, according to a new study conducted primarily by scientists from Germany and the United Kingdom. The participating researchers investigated which climate policies were particularly effective. Reduced emissions have generally been the result of ambitious, i.e., larger and stricter climate policy portfolios. In addition, countries targeting the largest sources of emissions were particularly successful, according to the experts from Heidelberg University, who played a major role in the study. The research findings are based on a statistical analysis ...

Wastewater contains untapped resources that, if reclaimed, could power agriculture, global sanitation, and its own treatment to help us meet UN SDG goals.   This is according to a new Frontiers in Science lead article in which researchers Prof Uwe Schröder, Prof Falk Harnisch, Dr Elizabeth Heidrich, and Dr Deepak Pant examine how microbial electrochemical technologies (METs) can convert organic waste streams into electricity, fuels, fertilizers, and usable water more efficiently. Pilot deployments—from the UK’s Glastonbury Festival to field trials in Uganda, Kenya, and South Africa—are demonstrating its ...

Whether it’s redfin pickerel in the Kennebec River or sturgeon in the Great Lakes, nearly one-third of freshwater fish species are facing possible extinction, threatening food supplies, ecosystems and outdoor recreation. As conservationists work to preserve these species, the University of Maine assistant professor Christina Murphy asked herself if there was an easier way to identify threats to fish before they become endangered.  After five years of data collection, programming and testing, Murphy and her colleagues developed a computer model that identifies potential threats to more than 10,000 freshwater species worldwide. Encouragingly, the majority of species accounted for ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent and based on the same physics, so all observed values of the Hubble constant should agree. But those that come from early-universe datasets disagree with those that come from late-universe datasets. This problem is known as the Hubble tension and is considered to be one of the most significant open questions in cosmology.  Now a team of astrophysicists, cosmologists, and physicists at The Grainger College of Engineering at the University of Illinois Urbana-Champaign ...

NYU scientists are using light to precisely control how tiny particles organize themselves into crystals.  Their research, published in the Cell Press journal Chem, provides a simple and reversible method for forming crystals that can be used to develop a new generation of adaptable materials. Crystals—from snowflakes and diamonds to the silicon used in electronics—are made up of particles arranged in repeating patterns. To study how crystals form, some scientists use colloidal particles—microscopic spheres suspended in liquid that self-assemble into colloidal crystals. Colloidal particles are also the building blocks for advanced ...
