For almost a century, the anonymous members of Nicolas Bourbaki have written books intended as pure expressions of mathematical thought.

Groundbreaking science is often the result of true collaboration, with researchers in a variety of fields, viewpoints and experiences coming together in a unique way. One such effort by Clemson University researchers has led to a discovery that could change the way the science of thermoelectrics moves forward.

Graduate research assistant Prakash Parajuli; research assistant professor Sriparna Bhattacharya; and Clemson Nanomaterials Institute (CNI) Founding Director Apparao Rao (all members of CNI in the College of Science’s Department of Physics and Astronomy) worked with an international team of scientists to examine a highly efficient thermoelectric material in a new way—by using light.

Their research has been published in the journal Advanced Science and is titled “High zT and its origin in Sb-doped GeTe single crystals.”

In the Nevada desert yesterday, Virgin Hyperloop tested human travel in a hyperloop pod for the first time.

SAN FRANCISCO – L3Harris Technologies will help the U.S. Defense Department extract information and insight from satellite and airborne imagery under a three-year U.S. Army Research Laboratory contract.

L3Harris will develop and demonstrate an artificial intelligence-machine learning interface for Defense Department applications under the multimillion-dollar contract announced Oct. 26.

“L3Harris will assist the Department of Defense with the integration of artificial intelligence and machine learning capabilities and technologies,” Stacey Casella, general manager for L3Harris’ Geospatial Processing and Analytics business, told SpaceNews. L3Harris will help the Defense Department embed artificial intelligence and machine learning in its workflows “to ultimately accelerate our ability to extract usable intelligence from the pretty expansive set of remotely sensed data that we have available today from spaceborne and airborne assets,” she added.

A Chinese team has demonstrated a prototype of a microwave plasma thruster capable of working in the Earth’s atmosphere and producing thrust with an efficiency comparable to the jet engines you’d find on modern airliners – under laboratory conditions.

Plasma thrusters are already operational on spacecraft as a means of solar-electric locomotion, using xenon plasma, but such things are no use in the Earth’s atmosphere, as accelerated xenon ions lose most of their thrust force to friction against the air. Not to mention, they only make a small amount of thrust in the first place.

There are around 300 million planets that exist outside our Solar System but within the Milky Way which could potentially harbour life. According to research from NASA, four of them are within just 30 light-years from Earth, with the closest just 20 light-years away, NASA claims.

They went in search of the Holy grail of astronomical research, scouring for the ‘Goldilock’s Zone’ where life may thrive.

The idea of terraforming Mars is a fascinating idea. … But just how long would such an endeavor take, what would it cost us, and is it really an effective use of our time and energy?

Ultimately, Yakovlev thinks that space biospheres could also be accomplished within a reasonable timeframe – i.e. between 2030 and 2050 – which is simply not possible with terraforming. Citing the growing presence and power of the commercial space sector, Yakovlev also believed a lot of the infrastructure that is necessary is already in place (or under development).

Have no fear: the Jolly Green II is finally here.

The Air Force officially took possession of its first two HH-60W Jolly Green II combat rescue helicopters at Moody Air Force Base last week, the service announced.

23rd Wing and 347th Rescue Group leadership took receipt of the new helos after they were flown from Lockheed Martin’s Sikorsky Training Academy in Connecticut to Moody AFB in Georgia by Air Force personnel.

There is a physical and electrical disconnect between the world of electronics and the world of biology. Electronics tend to be rigid, operate using electrons, and are inherently two-dimensional. The brain, as a basis for comparison, is soft, operates using ions, and is three-dimensional. Researchers have therefore been looking to find different routes to create biocompatible devices that work well in wet environments like biological systems. In an exiting new development, researchers from North Carolina State University have fabricated a memory device that is soft, entirely based on liquid-based matter, and functions well in wet environments — opening the door to a new generation of biocompatible electronic devices.
