Imagine a vast grassy plain covered with massive herds of elephants, bison and camels stretching as far as the eye can see. Lions, tigers, wolves and later, humans, hunt the herds on their summer migration. Where is this? This was the Bay Area during the close of the last Ice Age. Take a trip to a time when the San Francisco Bay was just a riverbed, 20,000 to 10,000 years ago.

California ranks second-lowest in the U.S. in fourth and eighth grade science achievement, according to a recent study. Since a large part of California's economy is devoted to technology, it is vital that California get its students up to speed. How bad is the problem? And what are schools and informal science education organizations doing to fill the gap?

For hundreds of years, scientists have been poaching design ideas from structures in nature. Now, biologists and engineers at UC Berkeley are working together to design a broad range of new products, such as life-saving milli-robots modeled on the way cockroaches run and adhesives based on the amazing design of a geckos foot. QUEST visits their labs to find out what's so special about these crawling and scaling animals.

Underwater Wilderness: Creating Marine Protected Areas

[LESS INFO] 37 VIEWS | ADDED 03:30:00 10/22/08
The waters off the coast of California are some of the richest in the world. But declines in fish species have led state leaders to begin creating large protected areas, or "no fishing zones," similar to wilderness areas on land. Although controversial with some fishing groups, the idea is to protect entire ecosystems instead of single species. The hope is that a statewide network may help bring back fish, birds and marine mammals that are currently on the brink.

Over the past 15 years, the number of people who die of AIDS each year in the United States has dropped by 70 percent. But AIDS remains a serious public health crisis among low-income African-Americans, particularly women. And in sub-Saharan Africa, the virus killed more than 1.6 million people in 2007. QUEST meets two Bay Area research groups studying innovative approaches that could lead to new treatments and possibly a cure.

Tracking Urban Lions
03/03/09

As the Bay Area has become more urban, many wild animals have disappeared. But not mountain lions. These large cats live surprisingly close to us, and yet they're not as dangerous as many believe. Now, researchers in the mountains north of Santa Cruz are using new technology to learn more about these elusive animals.
