Expo seeks to inspire new generation of robot-builders
Robots that can transfer plastic rings. Robots that can toss Frisbees into targets. Robots that can climb, swim, dance, or make music. Robots that can clean up a nuclear plant after a Fukushima-style disaster, sparing human beings the risk of radiation poisoning.
UN official hopeful about 2015 climate talks
DUBAI, United Arab Emirates — Governments are more serious and the impact of climate change is more dramatic, improving chances of a groundbreaking global warming pact in 2015 in contrast with the failure of such an effort in 2009, the U.N. climate chief said Tuesday.
Whiz kids show their stuff at White House science fair
In his dark blue business suit, President Barack Obama climbed onto a bicycle anchored to the ground outside the White House. He pedaled in his polished dress shoes, generating electricity to run a water sanitation system built by a group of Florida teenagers.
How Rocking a Baby Is Like Holding a Kitten by the Neck
A human mother rocking a baby in her arms and a cat carrying her kitten by the scruff of its neck have the same physiological effect on both young animals and probably stem from the same maternal instinct to protect their young. That's the conclusion of a new study, which for the first time has compared the physiological impact of maternal carrying behaviors across species. The findings may lead to better parenting techniques for people and possibly to new ways to detect developmental disorders early in life.
'Living Fossil' Gets Its Genome Sequenced
The coelacanth isn't called a "living fossil" for nothing. The six-foot-long, nearly 200-pound fish was thought to have gone extinct 70 million years ago — until a fisherman caught one in 1938 — and the animal looks a lot like its fossil ancestors dating back 300 million years. Now, the first analysis of the coelacanth's genome reveals why the fish may have changed so little over the ages. It also may help explain how fish like it moved onto land long ago.
Ancient Mating Dance Offers Ranchers, Birds a Lifeline
BURWELL, Neb. — Under an indigo pre-dawn sky, as a frigid wind whipped across the plains, a half-dozen brown-and-white birds emerged from tufts of dry grass. They emitted a low cooing sound, akin to the hooting of an owl.
Everybody Talks About the Weather, but It's Not Easy to Predict
I remember my first-grade teacher, Ms. Neely, telling our class that "March comes in like a lion and goes out like a lamb." I now understand that this old saw is based on the fact that winter turns to spring during the month, but I grew up outside Syracuse, N.Y., where even late March tends to be quite leonine, so it baffled me endlessly as a child.
As Bird Flu Concerns Rise, Herbal Remedies Sell Out
HONG KONG — A popular herb called ban lan gen, or blue root, has been flying off pharmacy shelves across China as local governments encourage people to consider traditional remedies to ward off the latest bird flu virus.

The number of U.S. children who died in 2011 within a year of birth in 2011 declined 12 percent from 2005, as fewer babies are born prematurely, health authorities reported.
Delayed Weaning May Reduce HIV in Milk of Breast-Feeding Mothers
NEW YORK — HIV-infected women who breastfed without supplementing their infants' diets with other fluids or foods for the first six months of life had lower levels of the AIDS virus in their milk, a study in Zambia showed.
