...levator cables that could lift payloads into Earth orbit to computers smaller than human cells. Thin films of carbon nanotubes deposited on transparent plastic can also serve as a surface on which cells can grow. And as researchers at the University of Texas Medical Branch at Galveston (UTMB) and Rice Un...

...to changes in the elliptical nature of the Earth's orbit combining with other factors, such as variations in its tilt or wobble. During the ice ages atmospheric CO2 was around 180 parts per million, compared to 280 parts per million during interglacials. We don't know quite why CO2 levels rose so much dur...

...f two centimetres. ESA has had radar altimeters in orbit since July 1991, when ERS-1 was launched, which was followed by ERS-2 in 1995 and Envisat in 2002 and will continue to launch radar altimeters with CryoSat planned for 2009 and Sentinel-3 planned for 2012.

...gularly engage in weight-bearing exercise while in orbit –?in order to stimulate integrin production and enhance or recover IGF-1 receptor function. The IGF-1 will act as a signaling device to allow Long to measure the strength of the interaction between integrins and IGF-1 receptor. "Understanding thi...
