Unlike seeds of other plants, orchid seeds (above, a seed packet) do not contain the nutrition they need to sprout. They get it from fungi.

Why the Conservation of Orchids Is No Simple Matter

Smithsonian's Sidedoor podcast visits with researchers working to understand the conditions these threatened plants need to grow

“Re:Frame,” a video web series produced by the Smithsonian American Art Museum, investigates the compelling role graphite has played in the history of art—and in Teresita Fernández’s work.

How Artist Teresita Fernández Turns Graphite, the Stuff of Stardust, Into Memories

A new episode of the Smithsonian’s ‘Re:Frame,’ explores the origin of graphite, a material artists have used for centuries

Ginkgo has survived three mass extinctions, including the one that killed the dinosaurs.

Smithsonian Scientists Are Using Ginkgo Leaves to Study Climate Change—They Need Your Help

Citizen scientists can submit leaf samples from their hometowns through the end of August

Researchers hypothesize that magnetic figures may have been crafted to memorialize the dead, with the attractive forces of the sculptures representing a lingering life force.

Mesoamerican Sculptures Reveal Early Knowledge of Magnetism

Stone figures with magnetized cheeks and navels suggest the pre-Maya civilization of Monte Alto understood the attractive force

Mosquitos and their related diseases played a role in many historical events.

How Mosquitoes Helped Shape the Course of Human History

Historian and author Timothy Winegard discusses the way mosquitoes have played a major role in battles, genetics and the gin and tonic

This bat gleans insects from leaves. A team of researchers discovered that by approaching a leaf at an oblique angle, it can use its echolocation system to detect stationary insects in the dark.

Bats Use Leaves as Mirrors to Locate and Catch Their Prey

The latest discovery in the arms race between bats and insects reveals that even silent, motionless dragonflies aren't safe

Opalised fossils from Lightning Ridge, N.S.W, Australia. From the collection of the Australian Opal Center. Clockwise from top left: freshwater snail; plesiosaur tooth; crocodile tooth; pine cone; pelvis bone of ornithopod dinosaur. Donated through the Australian Government’s Cultural Gifts Program by (respectively) Down to Earth Opals, Timothy Seekamp, Stephen Turner and Michael Poben.

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational redshift that is predicted by Einstein's general relativity. By observing this redshift, we can test Einstein's theory of gravity.
