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.....»»
