Low oxygen levels are pushing fish into shallower waters
Fish can drown. While it may not seem like it, fish do require oxygen to breathe; it's just that they get what they need from the oxygen dissolved in water rather than in the air. Too little oxygen spells trouble for our finned friends, which have to.....»»
A growing number of Canadian households contain dangerous levels of radon gas, finds survey
The 2024 Cross-Canada Survey of Radon Exposure in the Residential Buildings of Urban and Rural Communities indicates that radioactive radon exposure in Canada is rising and continues to be a critical public health concern......»»
"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
Insect and spider biodiversity increases organic nutrient availability across ecosystems, large-scale study shows
Insects and spiders are important elements in the food webs of aquatic and terrestrial ecosystems. With declines in their biodiversity, the food supply for birds, fish, reptiles, amphibians and small mammals is not only becoming scarcer, but also poo.....»»
Future atmospheric rivers could bring catastrophic ocean level rise off the West Coast, simulation study shows
A team of climate specialists from the NSF National Center for Atmospheric Research, Climate and Global Dynamics Lab, Texas A&M University, and Pennsylvania State University has found evidence for a rise in ocean levels during future atmospheric rive.....»»
Risk of cardiovascular disease linked to long-term exposure to arsenic in community water supplies
Long term exposure to arsenic in water may increase cardiovascular disease and especially heart disease risk even at exposure levels below the federal regulatory limit (10µg/L) according to a study at Columbia University Mailman School of Public Hea.....»»

Pilot expeditions work to preserve the white shark in the Mediterranean Sea
The Mediterranean Sea is a paradise. Pristine waters and an incredible coastline spanning multiple continents are renowned the world over. Below those picturesque, and sometimes crowded, waters swims a legendary creature facing a treacherous and unce.....»»
Genomic study offers hope for endangered Oriental stork
A new genomic study of the endangered Oriental stork reveals that the population's genetic health is still surprisingly strong, with high genetic diversity and low levels of inbreeding. This is an uncommon finding in most endangered species populatio.....»»
Evolution in action: How ethnic Tibetan women thrive in thin oxygen at high altitudes
Breathing thin air at extreme altitudes presents a significant challenge—there's simply less oxygen with every lungful. Yet, for more than 10,000 years, Tibetan women living on the high Tibetan Plateau have not only survived but thrived in that env.....»»
Bizarre fish has sensory “legs” it uses for walking and tasting
Some sea robin species can use their legs to sense prey. Evolution has turned out bizarre and baffling creatures, such as walking fish. It only gets weirder from there. Some of th.....»»

Formula 1® is one of the most advanced sports in the world, known for pushing the boundaries of automotive engineering, aerodynamics, and data analysis. Not only are cars constructed with cutting-edge materials using advanced aerodynamic research, t.....»»
Better ocean connectivity boosts reef fish populations, finds study
Research led by the University of Oxford has found that oceanographic connectivity (the movement and exchange of water between different parts of the ocean) is a key influence for fish abundance across the Western Indian Ocean (WIO). The findings are.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
New method for measuring luminescence lifetime offers versatility in scientific imaging
Oxygen is a key molecule for life, and in order to understand ecosystem dynamics it can be important to follow its ways in much detail. Optical sensors that use luminescent dyes have long been used to map oxygen levels in marine systems. Oxygen reduc.....»»
Higher oxytocin levels linked to reproductive success and better cooperation in house mice
Researchers have further advanced understanding of social relationships in female mammals, highlighting the critical role oxytocin plays......»»
How the invasive spiny water flea spread across Canada, and what we can do about it
Across the tranquil waters of Canada's vast network of lakes and rivers, a quiet invader is on the move. The spiny water flea, Bythotrephes cederströmii, is a microscopic predator that is forever altering the ecological fabric of aquatic habitats in.....»»
