The Smithsonian’s ‘Lights Out’ inspires visitors to save the fading night sky
The exhibition examines how light pollution harms astronomy, ecosystems and human cultures. But it also offers hope.

This sea cucumber shoots sticky tubes out of its butt. Its genes hint at how
A new genetics study is providing a wealth of information about silky, sticky tubes, called the Cuvierian organ, that sea cucumbers use to tangle foes.

‘Jet packs’ and ultrasounds could reveal secrets of pregnant whale sharks
Only one pregnant whale shark has ever been studied. New underwater techniques using ultrasound and blood tests could change that.

Invasive yellow crazy ants create male ‘chimeras’ to reproduce
Yellow crazy ants are first known species where chimerism is required in males: Each of their cells holds DNA from just one of two genetic lineages.

How some beetles ‘drink’ water using their butts
Red flour beetles, a major agricultural pest, suck water out of the air using special cells in their rear ends, a new study suggests.

Capybaras thrive, even near humans, because they’re not picky eaters
Scientists didn’t expect capybaras to eat both grasses and forest plants. The rodents’ flexible diet helps them live everywhere from cities to swamps.

Volcanic sulfur may make barn owls grow redder feathers
Barn owls on volcanic islands tend to have redder plumage than those on nonvolcanic islands, possibly due to an influx of sulfur in the environment.

These transparent fish turn rainbow with white light. Now, we know why
Repeated structures in the ghost catfish’s muscles separate white light that passes through their bodies into different wavelengths.

Scientists have now recorded brain waves from freely moving octopuses
The data reveal some unexpected patterns, though it’s too early to know how octopus brains control the animals’ behavior, a new study finds.

Static electricity helps parasitic nematodes glom onto victims
The small electric charge generated by a moving insect is enough to affect the trajectory of a parasitic nematode’s leap so it lands right on its host.

A ‘fire wolf’ fish could expand what we know about one unusual deep-sea ecosystem
Unlike other known methane seeps, Jacó Scar is slightly warmer than the surrounding water and is a home for both cold-loving and heat-loving organisms.
