San Francisco's Marina District is being invaded by frogs, thanks to an exhibit at the Exploratorium. "Frogs," running next Saturday through Sept. 12, will have tubfuls of live frogs, toads and tadpoles, plus more than 20 educational exhibits. You can compare your heartbeat to a frog's, check out its innards through computer simulation and match your attempt at a frog call against the real thing (monitored by a voice-spectrum gizmo).

"I wanted to design objects with a sense of humor that are sophisticated enough to endure," says 32-year-old Sallie Trout of her collection of whimsical decorative hardware. What she's created would make even a palace guard smile. Her doorknobs and finials, hooks and drapery tiebacks come in an array of offbeat motifs, from rocket ships and coffee cups to lips, eyes and hearts. There's even a drawer pull in the shape of a melting cross. She calls it "Sinead," after the rebellious Irish singer.

An unusually high number of mountain lion sightings in the city--including one this week--has forced the indefinite closure of the 150-acre trail area at the William R. Mason Regional Park for the first time in decades, officials said Friday. "To be on the safe side, we decided to shut it down," said Jerry F. Lahart, the supervising park ranger. Officials began posting new red and white warning signs around the park on Friday.

Southern California's mountain yellow-legged frog has made a remarkable leap toward recovery for an endangered species, rebounding in just two years from near-extinction brought on by development, fires, fungal infections and predatory trout, federal biologists said on Monday. In 2010, only 200 remained in isolated wild populations, prompting federal wildlife authorities and zoos in Fresno, Los Angeles and San Diego to launch an ambitious recovery program that included captive breeding facilities, trout removal programs and barring public access to areas where frogs were clinging to existence.

John Gurdon and Shinya Yamanaka were jointly awarded the Nobel Prize in Physiology or Medicine on Monday for their research on resetting cells to their earliest developmental stages. The work has yet to yield a clear breakthrough in medical treatment, but it has revolutionized scientists' ability to study both normal and diseased development. Gurdon, 79, performed his seminal work in the late 1950s and early 1960s - a good deal of it before Yamanaka was born. In his most famous study, Gurdon showed that replacing the nucleus of an adult cell with the nucleus of an embryonic cell reset the adult cell to an embryonic state: Many of the cells became tadpoles.

Are you curious about the potential of hamsters to breed in the wild? Do you care about pocket gophers gnawing on electrical cables? Did you ever wonder about the value of acorns in the diet of steers? If so, you can find the answers in research reports from an experimental cattle range in the Sierra Nevada foothills of Central California.

Southern California's largest population of red-legged frogs, a threatened species that has found itself in the middle of legal battles between environmentalists and homebuilders, may be living along a creek north of Santa Clarita, federal biologists said Monday. Scientists originally estimated that 50 of the 5-inch-long amphibians were living along San Francisquito Creek in the Angeles National Forest.
