Ancient stardust in meteorite is older than Earth
Grains of stardust – particles left behind by star explosions – in an Australian meteorite are now the oldest known material on Earth. A new study suggests this stardust came to be long before our sun ever existed.
Male sparrows are less intimidated by the songs of aging rivals
Few singers reach their sunset years with the same voice they had in younger days. Songbirds are no different. New research reveals that elderly swamp sparrows don’t sound quite like they used to — nor do they strike the same fear in other males who may be listening in. Humans are remarkably good at guessing a person’s age by their voice. But this is the first time the phenomenon has been demonstrated in wild animals.
Not all of nature’s layered structures are tough as animal shells and antlers
Engineers looking to nature for inspiration have long assumed that layered structures like those found in mollusk shells enhance a material’s toughness, but a study shows that’s not always the case. The findings may help engineers avoid ‘naive biomimicry, the researchers say.

A new way to detect oxygen in exoplanet atmospheres
In recent years, astronomers have pondered the search for biosignatures, or signs of life, in the atmospheres of distant exoplanets. Will the James Webb Space Telescope – due to launch in 2021 – be able to detect them? A new technique says yes.
Transformational innovation needed to reach global forest restoration goals
(University of Maryland Baltimore County) New research finds that global South countries have pledged the largest areas of land to forest restoration, and are also farthest behind in meeting their targets due to challenging factors such as population growth, corruption, and deforestation. ‘We’ve identified countries that need help, not failures,’ says UMBC’s Matt Fagan. With the right kind of international support — that listens to locals and generates creative solutions — communities can implement policy that will make positive change.
