Male lemurs mix their scented secretions to send long-lasting messages to one another.
When a shy fish ventures into the unknown, it prefers to follow a fish with a similarly cautious personality.
New research on mice demonstrates a way to use designer bacteria as a non-invasive test for cancer.
Thirteen times a century, on average, Mercury passes directly between Earth and the sun, creating what astronomers call a transit. It just happened again; this video, created with images from the orbiting Solar Dynamics Observatory shows the tiny planet’s silhouette as it makes its seven-hour journey across the solar disk.
Plug a shark’s nose, and it’ll have a hard time getting home.
In this episode of Richard Garriott's miniseries, he shows us how Earth formed, how remnants of that formation still wander the solar system and how our planet came to be covered by oceans.Next week: Life on Earth Begins

Globe skimmer dragonflies migrate more than 15,000 kilometers, breeding with the locals as they travel and creating an interrelated global population. A dragonfly from Japan may have more in common with Guyanese dragonflies, genetically speaking, than its own Japanese cousins.

Scientific American reconstructed this rotation of Earth from images taken by the high-resolution EPIC camera onboard the satellite DISCOVR. The satellite is between Earth and the sun.
Death Valley, straddling California and Nevada, blooms a little every spring. But when conditions are right, including well-spaced rainfall and low winds, the desert becomes carpeted with wildflowers. This year the conditions were just right. Rains were gentle and penetrated deeply into the soil to germinate dormant seeds. The ground warmed slowly, allowing roots to develop. A moist, El Niño weather pattern kept the flowers watered as they grew. Check here for a map showing where the flowers are now. Blooms start in the valleys and work their way up to the tops of the mountains through the spring and early summer.
