Migratory monarch butterfly populations have fallen into a tailspin in recent years. Scientists fear that in a classic case of good intentions gone awry, efforts to help the beleaguered butterflies may be inadvertently making matters worse by changing their behavior.
If you want to go to Mars but can’t quite afford the hundreds of billions of dollars for a ticket, there is another solution: consider instead a trip to the Atacama Desert in Chile.
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.
But the virus isn't new to sea stars, so what triggered the current outbreak remains a mystery.
Through centuries of exploration, humans have climbed the highest peaks and hacked through the densest jungles. From pole to pole, there isn't a continent left unexplored, and very little land on earth that has not been set foot on by a human being. Yet only 10 percent of the world’s vast oceans have been truly explored. ...Read More
Birds, salmon and snakes depend on marshes and rivers for survival and migration, and to propagate the species. But many wildlife species are unable to find the water they need as the drought shrinks rivers and dries up wetlands.
In a technological tour de force, a group of scientists have managed to read most of the DNA from the thigh bone of a 45,000 year-old-man. They were able to estimate that humans and Neanderthals bred in a major way 50,000-60,000 years ago and to confirm that the human mutation rate is a bit slower than scientists previously thought.
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.
Voters in Oregon will head to the polls Nov. 4 to decide whether to require foods made with genetically engineered ingredients to be labeled. In doing so, they'll be voting on an initiative shaped in part by the experience of activists in California, who watched a similar measure fail ...Read More
While many of the benefits of antioxidants are undoubtedly oversold, we do know that if given at high enough levels and targeted to the right place, antioxidants can help a mouse live 10-20% longer. If this holds up in people, that is equivalent to an extra 7-14 years for people here in the U.S.
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.
“Experimental Space” is the latest show at Oakland art gallery Aggregate Space, consisting of images and videos created by scientists in the course of their research.

A highly endangered species exists on the urban edge of Redwood Regional Park in Oakland. Find out what volunteers and the East Bay Regional Park District are doing to protect and restore the serpentine prairie.
Direct-to-consumer (DTC) genetic tests are a fun way to learn about your family history, ancestry and maybe even a bit about your future health risks. But sometimes, they can also lead to unforeseen negative consequences.
All is not well with the nation's birds. The most comprehensive study ever of birds in America is out today, and it says many populations are in steep decline, even as others are doing well. The report, called "The State of the Birds," comes from the federal government, universities and ...Read More
People in Maryland love their Baltimore orioles — so much so that their major league baseball team bears the name of the migrating bird. Yet, by 2080, there may not be any orioles left in Maryland. They migrate each year and, according to a new report, could soon be forced ...Read More
Scientists recently fixed a broken gene in a fertilized mouse egg and prevented the mouse from getting an ultimately fatal form of muscular dystrophy. This study may one day translate into gene therapies that will treat and maybe even reverse certain effects of the disease.
One of the key fisheries on the West Coast is coming back after years of decline.
