What does it mean to be blue? The wings of a Morpho butterfly are some of the most brilliant structures in nature, and yet they contain no blue pigment -- they harness the physics of light at the nanoscale.
The year-over-year water-saving rate slid by more than a third in October, worrying officials calling on residents to reduce water usage during record drought.
California homeowners are replacing Kentucky bluegrass with native species and other water-friendly options to try and cut back on outdoor watering. Depending on what replacement residents choose, water districts may offer a cash reward for tearing out that thirsty lawn.
Plenty of animals build their homes in oak trees. But some very teeny, tricky wasps make the tree do all the work. “What nerve!” you might say. What… gall! And you’d be right. The wasps are called gall-inducers. And each miniature mansion that the trees build for the wasps' larvae is weirder and more flamboyant than the next.
Scientists say it’s possible California’s drought may last a lot longer than a few years. No one knows for sure, but we could all simply have to adjust to a drier climate. That could mean changing the way we build cities to make them more porous. The 'Hydramax,' a futuristic design pictured above, rises with the tide and captures water from the air.
But the virus isn't new to sea stars, so what triggered the current outbreak remains a mystery.
And a trick to prevent seasickness that the skipper swears by (other than staying ashore).
Passage of two out of three local measures may just set the stage for next battle.
A local environmental group is declaring victories for open space preservation and smart growth in the Bay Area.
Who's using the most -- and the least water? The numbers are in -- but officials warn that they can be misleading.
There’s a story in every grain of sand: tales of life and death, fire and water. If you scooped up a handful of sand from every beach, you'd have a history of the world sifting through your fingers. From mountain boulders to the shells of tiny ocean creatures, follow the journey that sand takes through thousands of years across entire continents to wind up stuck between your toes.
The last of the Coast Guard's big icebreakers departs San Francisco Bay this week, a rare sight on the Bay and a reminder that the U.S. is falling behind in the race for polar dominance -- and knowledge.
Startling maps in a new report on the Sacramento-San Joaquin Delta show the dramatic loss of marshlands that once supported a vast array of wildlife.
An environmental group claims there are unanswered questions about the seismic safety of the Central Coast plant.
The Bay Area Science Festival features events like a bike ride through wetland and a tour of a UPS facility. It begins Thursday, October 23, and will host 56 events over ten days.
In response to concerns about the risks of crude by rail, Union Pacific has begun to boost its rail inspection program by dispatching vehicles with lasers that can find tiny track imperfections.
Tiny and delicate, pygmy seahorses survive by attaching to vibrant corals where they become nearly invisible to both predators and researchers. Now, biologists at the California Academy of Sciences have successfully bred them in captivity for the first time. Finally, they're able to study the seahorses' amazing act of camouflage up close.
Scientists in California's Central Valley are testing the nutrient content of fruits grown with less-than-normal amounts of water. And the findings so far are raising a question: will consumers buy fruits that are just as nutritional, or sometimes higher in antioxidants, if they aren't as pretty?
