The dogged pursuit of a South Korean research team has produced Snuppy, the world's first cloned canine. (p. 83)

Astronomers have found a body larger and more distant than Pluto, the biggest object found in the solar system since Neptune and its moon Triton were discovered in 1846. (p. 83)

Women who go severely hungry during early pregnancy face twice the normal risk of having a child who develops schizophrenia in adulthood. (p. 84)

By squeezing a mineral sample to pressures higher than those deep within Earth, then zapping it with a laser, scientists have created a crystalline form of silicon dioxide previously unknown on Earth. (p. 84)

The first lab-ready technology to challenge the dominant gene-sequencing technique known as the Sanger method taps miniaturization and parallel reading of hundreds of thousands of DNA stretches to boost speed and slash cost. (p. 85)

Adding heat sensitizes tumor cells to the effects of a genetically modified virus, which then can kill them. (p. 85)

Technological problems for NASA's space shuttle Discovery, such as falling foam and dangling insulation, are causing safety worries and throwing a crimp into the U.S. space program. (p. 86)

New robots based on the mechanics of human walking use less energy and move more naturally than traditional bipedal robots do, suggesting new ways to approach two-legged robots and prosthetic design. (p. 88)

Anatomically modern people evolved in small groups of ancient Homo sapiens that never traveled too far but continually interbred with nearby groups, including other Homo species, creating a genetic wave that moved from Africa across Asia, a new model suggests. (p. 91)

Some of the organic material carried to the sea by the Amazon is thousands of years old, but much of the carbon in carbon dioxide emanating from the river was stored in plants for less than a decade. (p. 93)

A chemical secreted by immune cells when people are stressed or sick causes a common gut bacterium to go on the offensive against its host. (p. 93)

The bacterium that causes Lyme disease commandeers a gene in the deer tick, inducing overproduction of a salivary protein that the bacterium uses to escape immune detection once it's inside a mammal. (p. 93)

Scientists have isolated mouth bacteria that consume the chemicals that cause bad breath. (p. 93)

The madness of England's King George III may have been partly due to arsenic poisoning. (p. 94)

A new model that describes airflow across the ocean's surface suggests that tiny droplets whipped from the tops of waves increase wind speeds well above what they'd be if the ocean spray wasn't there. (p. 94)

A survey of a segment of Antarctic seafloor that until recently had laid beneath a thick, floating ice shelf for thousands of years has revealed an ecosystem apparently based on chemical nourishment, not sunshine. (p. 94)
