Separate polarization and brightness channels give crabs the edge over predators

Fiddler crabs see the polarization of light and this gives them the edge when it comes to spotting potentials threats, such as a rival crab or a predator. Now researchers have begun to unravel how this information is processed within the crab's brain. The study has discovered that when detecting approaching objects, fiddler crabs separate polarization and brightness information.

Extreme wildfires threaten to turn boreal forests from carbon sinks to carbon sources

A research team investigated the impact of extreme fires on previously intact carbon stores by studying the soil and vegetation of the boreal forest and how they changed after a record-setting fire season in the Northwest Territories in 2014. They collected 200 soil samples and used radiocarbon dating to estimate the carbon age. They found combustion of legacy carbon in nearly half of the samples taken from young forests (less than 60 years old).

Cannabis flower is an effective mid-level analgesic medication for pain

Fecal transplants to help save koalas

Fecal transplants are helping expand koala microbiomes, allowing the marsupials to eat a wider range of eucalypts and possibly survive habitat loss. A study has analyzed and altered microbes in koalas' guts, finding that a fecal transplant may influence what species of eucalypt koalas can feed on.

A lack of self control during adolescence is not uniquely human

Impulsiveness in adolescence isn't just a phase, it's biology. And despite all the social factors that define our teen years, the human brain and the brains of other primates go through very similar changes, particularly in the areas that affect self-control.
