Obayashi’s Space Elevator to Be Operational by 2050

obayashi-space-elevator

The holy grail of getting into orbit has always been the ultimate development of space elevators, long, thin strands that could ferry passengers and cargo into orbit at minimal expenditure. Now a Japanese company, Obayashi Corp, specializing in engineering and construction, announced that it aims to complete a space elevator by 2050.

Researchers at the Oak Ridge National Laboratory (ORNL) think that they could use graphite foam to harness energy from the temperature gradient in tropical waters, where the difference between surface and bottom varies as much as 70 to 80 degrees.

Friction on Raindrops Dissipates Almost as Much Atmospheric Energy as Turbulence

rainfall-drag

A new study published in the journal Science states that rainfall soothes the atmosphere, almost as much as turbulence. They calculated that a substantial portion of the energy that drives wind and air circulation in the Earth’s atmosphere is dissipated as friction by raindrops falling through the air.

Plankton-Fueled Agulhas Current Ocean Eddy is 93 Miles Wide

plankton-eddy

Deep below the ocean’s surface, huge eddies are often formed. The depths have their own kinds of weather systems. NASA’s Terra satellite captured this photo of a gigantic plankton-fueled eddy that was released. The eddy is completely submerged under water.

Microbial Oasis Discovered Under Atacama Desert in Chile

atacama-desert

Researchers have discovered a veritable microbial oasis, under the Atacama Desert in Chile. The region is known for the Atacama Large Millimeter/submillimeter Array (ALMA), but the discovery of a hypersaline subsurface microbial habitat, associated with halite-, nitrate-, and perchlorate-containing salts, lying at a depth of 2m in the driest desert on Earth will give scientists more reasons to visit the region.

Drexel University Researchers to 3D-Print Dinosaur Bones

laser-scanning-fossil-bone

Researchers at Drexel University are planning to print robotic dinosaurs that have been cast from real fossils, in an effort to better understand them. Kenneth Lacovara, a paleontologist, has combined forces with James Tangorra, a mechanical engineer, to learn more about dinosaur locomotion.

Iridescent Butterfly Wing Properties to Lead to Better Thermal Imaging Cameras

iridescent-butterfly-wings

Researchers studying the iridescent properties of butterfly wings think that this could help engineers develop temperature sensors that are smaller and faster. This technology could work without the need for cumbersome cooling techniques, something that has always been needed in thermal imaging and medical diagnostics.
