AAAS 2005 Annual MeetingSpit, and call me in the morning
The eyes may be the window to the soul, but many scientists would say the mouth is the window to the body.

AAAS 2005 Annual Meeting ScienceRobots walk with close-to-human efficiency
Researchers at Cornell University, the Massachusetts Institute of Technology and Holland's Delft University of Technology have built robots that seem to closely mimic the human gait, and the Cornell robot matches human efficiency. The inspiration: simple walking toys.

AAAS 2005 Annual Meeting ScienceTeams build robots that walk like humans
Three independent research teams, including one from MIT, have built walking robots that mimic humans in terms of their gait, energy-efficiency, and control. The MIT robot also demonstrates a new learning system that allows the robot to continually adapt to the terrain as it walks.

NatureSaturn's aurora defy scientists' expectations
Aurora on Saturn behave in ways different from how scientists have thought possible for the last 25 years, according to new research by a team of astronomers led by John Clarke, a professor in Boston University's Department of Astronomy. Clarke and his team found that the ringed planet's aurora, long thought of as a cross between those of Earth and Jupiter, may, in fact, be a phenomenon unique within our solar system.

NatureResearchers find Saturn's radio emissions, bright auroras linked
Just as the static on an AM radio grows louder with the approach of a summer lightning storm, strong radio emissions accompany bright auroral spots -- similar to Earth's northern lights -- on the planet Saturn, according to a research paper published in the Thursday, Feb. 17 issue of the journal Nature.

NatureThe oldest Homo sapiens
When the bones of two early humans were found in 1967 near Kibish, Ethiopia, they were thought to be 130,000 years old. A few years ago, researchers found 154,000- to 160,000-year-old human bones at Herto, Ethiopia. Now, a new study of the 1967 fossil site indicates the earliest known members of our species, Homo sapiens, roamed Africa about 195,000 years ago.

Astronomical JournalNASA observatory confirms black hole limits
The very largest black holes reach a certain point and then grow no more. That's according to the best survey to-date of black holes made with NASA's Chandra X-ray Observatory. Scientists also discovered previously hidden black holes well below their weight limit.

Melas, Candor and Ophir Chasmas: Centre of Valles Marineris
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the central part of the 4000-kilometre long Valles Marineris canyon on Mars.

Space 'eye' for textiles
An artificial eye developed for Earth observation is now being employed to recognise colour variations in dyed fabrics: a critical element of textile production. This could significantly reduce the 160 million metres of dyed fabrics discarded annually in Europe with high environmental costs.
