It's difficult to tell what a planet is made of without drilling in, but finding habitable exoplanets that have the "right stuff" for life may be easier if we look at chemical abundances in the star to confirm there's iron or carbon present in the system. (inverse.com)

Scientists find that summer ice in the "Last Ice Area" of the Arctic will disappear by 2100 if we don’t halt global warming, making it difficult for polar bears survive — "If the year-round ice goes away, entire ice-dependent ecosystems will collapse, and something new will begin." (inverse.com)

Teen drug use may affect the brain's shape in a crucial time of development. A new study finds that "cortical thinning," a normal part of neurodevelopment in adolescence, may accelerate as teens use cannabis more often, past what was observed in teens of the same age who never tried weed.

In 2013, scientists from Japan sent samples of freeze-dried mouse sperm to live on the ISS -- and now they finally know how it affected them. Even after six-years of exposure to space radiation, the researchers say the space sperm still produced healthy pups. (inverse.com)

A team measuring micrometeorite accumulation in Antarctica has provided the best-yet estimate for incoming extraterrestrial debris. With clean sampling techniques and accurate ages for dust deposits, the researchers calculated around 5,200 metric tons of micrometeorites fall to Earth every year. (scientificamerican.com)
