Yesterday I suffered a mysterious blog FAIL around 1 or 2 pm eastern time. Half of my post about desmids — intricate, microscopic plants — vanished within an hour or so of publication. I didn’t realize it until around 6 pm, when I fixed it. So if you read my post yesterday but there weren’t [...]

Leafy Green ‘Solar-Powered’ Sea Slugs Begin to Reveal Their True Colors

Nature is full of thieves. Instead of laboriously collecting pollen and nectar from flowers, robber bees raid the hives of other pollinators and steal the honey within. Some ant species routinely kidnap and enslave members of neighboring colonies, taking tens of thousands of pupae in a single season. And massive-winged frigate birds—also called pirate birds—swoop [...]

Will Humanity Face a Carbohydrate Shortage?

farmland-from-space

Photosynthesis is the single most important transformation on Earth. Using the energy in sunlight, all plants—from single-celled algae to towering redwoods—knit carbon dioxide and water into food and release oxygen as a byproduct. Every year, humanity uses up roughly 40 percent of the planet’s photosynthesis for our own purposes—from feeding a growing population to biofuels. [...]

Green Chemistry’s Real Roots [Video]

Plants mastered chemistry a long time before humans, billions of years actually. In fact, we humans and most of the rest of the life on Earth can thank tiny cyanobacteria for mastering/evolving the molecule known as chlorophyll. Chlorophyll—a pigment that absorbs blue light—is the key to photosynthesis, and photosynthesis is the key to turning sunlight [...]

Shift happens: Will artificial photosynthesis power the world?

One drinking-water bottle could provide enough energy for an entire household in the developing world if Dan Nocera has his way. A chemist from M.I.T. and founder of the company Sun Catalytix, Nocera has developed a cobalt-based catalyst that allows him to store energy the same way plants do: by splitting water. "Almost all the [...]
