Harvard researchers grew these lovely microscopic gardens using delicate chemical reactions.
A nanorose may not smell as sweet as an organic one, but the red petals on this micron-scale flower are unquestionably just as beautiful. At Harvard University, materials scientists have perfected an underwater chemical reaction that results in these gorgeous, self-assembling nanoflowers. The microscopic structures are crystals that build themselves, one molecule at a time, on a glass surface submerged in a beaker of water, barium chloride, and sodium silicate. When carbon dioxide from the air naturally dissolves in the water, it sets off the chemical reaction that causes the crystals to form. Though the colors in these images are artificial, the intricate shapes of the nanoflowers are very real. The twists, curves, and ruffles are created when the scientists shift the components of the chemical reaction; the crystals naturally “grow” toward or away from various chemical gradients. For example, the broad-leaf shapes you’ll see in the gallery formed in solutions with extra carbon dioxide. “When you look through the electron microscope, it really feels a bit like you’re diving in the ocean, seeing huge fields of coral and sponges,” says Wim L. Noorduin, a postdoctoral fellow at Harvard and lead author of the paper in Science. “Sometimes I forget to take images because it’s so nice to explore.” Click here to see more of these amazing creations.

Comprehensive sex education is what both men and women need to be informed. Without information, young women and girls are more likely to have an unplanned pregnancy or get an STD/STI. Also, when people have more information on sex, how to say no, when to say no, and most importantly, to…
Anthropologists have discovered a beautiful Greek waterfront paradise once inhabited by generations of Neanderthals up to 100,000 years ago, according to a new study.
This particular population was based at what is known as The Kalamakia Middle Paleolithic Cave site on the Mani peninsula of…
Archaeologists in Mexico have found 4,926 well-preserved cave paintings in the north-eastern region of Burgos.
The images in red, yellow, black and white depict humans, animals and insects, as well as skyscapes and abstract scenes.
The paintings were found in 11 different sites - but the…
Early on the morning of May 13, 1862, a lookout on the U.S.S. Onward spotted a Confederate steamer heading out of Charleston Harbor directly toward the Union blockade. Commander F.J. Nickels was about to fire when he saw that the steamer was flying a white flag. “The steamer ran alongside and I…
