Scientists confine, study Chinook at restored Snoqualmie River habitat
In newly restored river channels on the Snoqualmie, baby Chinook salmon are confined in 19 enclosures about the size of large suitcases as they munch on little crustaceans and invertebrate insects floating or swimming by......»»
Researcher finds that wood frogs evolved rapidly in response to road salts
When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research published in Ecology and Evolution a team led by Rick Relyea, Ph.D., professor of biological sciences and David M. Darrin Senior Endowed.....»»
A NASA rover has reached a promising place to search for fossilized life on Mars
While we go about our daily lives on Earth, a nuclear-powered robot the size of a small car is trundling around Mars looking for fossils. Unlike its predecessor Curiosity, NASA's Perseverance rover is explicitly intended to "search for potential evid.....»»
Leaf size and defensive traits found to modulate effects of soil fauna on litter decomposition
Leaf litter, as a multifunctional legacy of plants, plays an essential role in driving biogeochemical cycles, while providing important habitat and food resources for soil organisms. Litter traits and soil fauna play a crucial role in determining lit.....»»
Spring iPhone sales slip to lowest activation share in years
The iPhone's slice of the smartphone activation pie has shrunk to its smallest size in six years, marking a concerning trend for Apple as it grapples with the longest gap yet between its iPhone releases.iPhone sales slip to lowest activation share in.....»»
Researchers unveil PI3K enzyme"s dual accelerator and brake mechanisms
A group of researchers have expanded conventional knowledge on a critical enzyme that controls cell migration. In a publication in the journal Nature Communications, they reported that phosphoinositide 3-kinase (PI3K) not only acts as an accelerator.....»»
Unveiling the mysteries of cell division in embryos with timelapse photography
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain elusive in the first cells of.....»»
A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. How did that come a.....»»
New method makes finding bat roosts easier for conservationists
A new algorithm is making it easier for ecologists and conservationists to find bat roost locations—reducing search areas by nearly 375 times their previous size. The technology combines microphone detector data with a bat movement model to identif.....»»
Bioluminescence first evolved in animals at least 540 million years ago, pushing back previous oldest dated example
