Geoneutrinos keep us warm? Measuring radioactive sources of Earth's heat

in technology, environment

What keeps the Earth cooking? Though the Earth has cooled since its formation,  the core of the Earth may be still as hot as 7000 K. The main source of Earth's internal heat is produced through decay of radiogenic isotopes, in particular radioisotopes of uranium, thorium and potassium. This process provides a continuing heat source in the Earth's interior.

Sandia’s “Cooler” technology offers fundamental breakthrough in heat transfer for microelectronics, other cooling applications

in technology

Sandia National Laboratories has developed the  “Sandia Cooler,” also known as the “Air Bearing Heat Exchanger,” a novel, proprietary air-cooling invention. The new technology has the potential to dramatically alter the air-cooling landscape in computing and microelectronics .

in technology, medicine, biology

A synthetic windpipe, seeded with patient's own stem cells, was successfully transplanted in a patient with tracheal cancer by physicians in Sweden. According to the hospital, the transplanted patient was recovering without the use of immunosuppressive drugs.

Changing Speed Of Light: Scientists drag light by slowing it to speed of sound

in technology

Does light travel at a constant speed in any medium? No. There is no doubt that thunder follows lightning, nevertheless, the speed of light can decrease depending on the medium in which it travels. A new paper in Science report that scientists have been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.

Sun and planets constructed differently, analysis from NASA mission suggests

in technology
The sun and the solar system's rocky inner planets, including the Earth, may have formed differently than previously thought, according to UCLA scientists and colleagues analyzing samples returned by NASA's Genesis mission.
