A group of high school students in San Francisco are using high-tech GPS cell phones to track their daily carbon footprint – and to gauge their daily environmental risk. The GPS tracks the students' trips and shows them how much carbon they use and are exposed to each week. As cell phones become more powerful, organizers hope to spread this movement virally.
Even in small amounts, lead can be poisonous. The California Attorney General's office is suing several manufacturers of artificial turf after lead was found in the pigment used to color it. Lead is especially harmful to children and that could be bad news around the state for anyone who has installed turf in playgrounds, soccer fields, child care centers and homes.
The predictions for climate change all warn that San Francisco Bay waters will rise. The latest estimate is the bay will be about 5 feet higher by the end of this century, and 16 inches higher by 2050. If the water rises high enough, a lot of expensive Bay-front property could be inundated. What can we do about it? And how do we plan for that? That's the subject of an innovative design contest that launches this week.
A single-family home with a yard and two-car garage may be the American dream for many Californians. But with real estate at a premium and traffic congestion getting worse, there is a new urban way of living that is becoming increasingly popular. Quest reports on the rise of the transit village and just why the trend has taken so long.
This year marks Charles Darwin's 200th birthday. One of the iconic fossils that supports Darwin's theory of evolution is called the Archaeopteryx and it was recently flown out to Stanford University for an unusual test. Scientists are bombarding this dino-bird with high-tech gadgetry to unlock even more information about how we came to be here.
Following the recent crash landing of a U.S. Airways jet into the Hudson River, QUEST takes a look at local efforts to avoid collisions between planes and birds. Every year pilots in the U.S. report more than 7,000 bird strikes. The Sacramento International Airport has one of the highest incidences of bird strikes in the nation, thanks to its location next to the Pacific Flyway.
Soon after Barack Obama is sworn in as President next week, he is expected to reverse the ban on federal funding for embryonic stem cell research. The resulting boom in this cutting-edge medical technology will benefit California's research institutes in a big way.
The Bush Administration has recently passed dozens of so-called "midnight regulations" – last-minute rules and amendments. Many of those new laws affect the environment, including a change to the Endangered Species Act that has California environmentalists deeply worried.
Some of the most common building materials – drywall, steel, cement – are among the biggest contributors to greenhouse gas emissions. Manufacturing them requires vast amounts of energy. Now, several Silicon Valley start-ups are looking for cleaner solutions and some of their efforts are drawing major venture capital.
Drivers are increasingly looking to their cell phones for advice on steering clear of heavy traffic. New technology from UC Berkeley uses cell phones to plot traffic patterns, giving a real-time picture of how long it takes to get from place to place. QUEST takes a ride with an early adopter.
That black, sooty exhaust from old diesel trucks may be a thing of the past. A landmark decision expected next week at the state Air Resources Board would mean California truckers must retrofit their diesel rigs at a price tag of about $5 billion. The cost is high, but given the health complications from diesel emissions, air pollution regulators feel they can't afford not to act.
UPDATE: Elizabeth Blackburn, a professor of biology and physiology at the University of California-San Francisco, on Monday was awarded the Nobel Prize in Medicine with Carol Greider and Jack Szostak for solving the mystery of how chromosomes protect themselves from degrading when cells divide. Blackburn was featured in this December QUEST radio report about the aging of HIV patients.
It's been a year since 53,000 gallons of oil from the Cosco Busan cargo ship spilled into the San Francisco Bay. More than half of that heavy bunker fuel is still around. Now, one challenge is trying to put the long-term effects of the spill into dollar terms, and then seek a settlement with the ship's owners. Officials say this work may set the national standard for handling man-made crises.
The Bay Area is synonymous worldwide with high-tech innovation. Meanwhile, its students have some of the lowest math and science scores in the country. Quest takes a look at the state of public school science education in California, and asks how the state can nurture a homegrown workforce equipped to take on 21st century challenges.
Last week's deadly earthquake in Japan and last month's devastating temblor in New Zealand have put quake-prone California on alert. While Bay Area residents would rather not think about the possibility of another major quake, the region is surrounded by active faults. One East Bay fault has scientists especially concerned.
Proposition 7 is all about renewable energy generation. The initiative requires all utilities to generate 20 percent of their power from renewable energy by 2010 and 50 percent by 2025 and speeds up approval of renewable energy plants. You would think most leading environmental groups would be on board — but many are not.
Imagine traveling from San Francisco to Los Angeles in about two-and-a-half hours, without getting on a plane. That's the idea that could become reality this November. A $10 billion bond project is on the ballot to build high-speed rail. With higher gas prices and concern about climate change, supporters hope the time is finally right to approve this massive mass-transit project. But technical and political obstacles remain.
It's that time of year again. Temperatures are hot, so we're cranking up the air conditioning. That means more electricity from the power grid, more greenhouse gas emissions, more global warming and — with warmer temperatures — even more air conditioning! There are a few ways to halt this vicious cycle, one of which starts with a makeover for the machine itself.
