New study on decomposing microbes could help transform forensic science

For the first time, researchers have identified what appears to be a network of approximately 20 microbes that universally drive the decomposition of animal flesh. The findings have significant implications for the future of forensic science, including the potential to provide crime scene investigators with a more precise way to determine a body’s time of death.

First-ever sighting of a live newborn great white may help solve longstanding mystery in shark science

"Where white sharks give birth is one of the holy grails of shark science. No one has ever been able to pinpoint where they are born, nor has anyone seen a newborn baby shark alive," Gauna said. "There have been dead white sharks found inside deceased pregnant mothers. But nothing like this."

As Arctic warms, caribou and muskoxen slow biodiversity loss

Diversity declined by about 0.85 species per decade when herbivores were excluded, whereas this decline was only about 0.33 species per decade when they were allowed to graze. The scientists attributed this to herbivores keeping species such as shrubs, dwarf birch and gray willow in check so that other plants could better flourish.
