Oshkosh can make 100% battery-electric delivery trucks for the U.S. Postal Service, likely dashing Workhorse’s hopes of reigniting the competition.

Oshkosh Truck Corp. (NYSE: OSK) can make 100% battery-electric delivery trucks for the U.S. Postal Service, undercutting an assertion by Workhorse Group (NASDAQ: WKHS) that its being passed over for the contract dooms the mail service to remaining a source of planet-warming greenhouse gas emissions.

SAN FRANCISCO — Kleos Space is conducting a six-month test of technology for in-space manufacturing of large 3D carbon fiber structures that could be used to construct solar arrays, star shades and interferometry antennas.

The company with operations in Luxembourg, the United States and United Kingdom is best known for radio frequency reconnaissance satellites. In the background, however, Kleos has been designing and developing in-space manufacturing technology called Futrism to robotically produce a carbon-fiber I-beam with embedded fiber-optic cables that is more than 100 meters long.

“It’s something that we have linked to our roadmap for RF, because it’s something that could deploy very large antennas for RF reconnaissance,” Kleos CEO Andy Bowyer told SpaceNews. “However, it’s useful for a whole range of other applications as well that we are very keen to work with partners on. We firmly believe that manufacturing in space is the future.”

Extremely precise measurements are possible using atom interferometers that employ the wave character of atoms for this purpose. They can thus be used, for example, to measure the gravitational field of the Earth or to detect gravitational waves. A team of scientists from Germany has now managed to successfully perform atom interferometry in space for the first time – onboard a sounding rocket. “We have established the technological basis for atom interferometry on board of a sounding rocket and demonstrated that such experiments are not only possible on Earth, but also in space,” said Professor Patrick Windpassinger of the Institute of Physics at Johannes Gutenberg University Mainz (JGU), whose team was involved in the investigation. The results of their analyses have been published in Nature Communications.

A team of researchers from various universities and research centers led by Leibniz University Hannover launched the MAIUS-1 mission in January 2017. This has since become the first rocket mission on which a Bose-Einstein condensate has been generated in space. This special state of matter occurs when atoms – in this case atoms of rubidium – are cooled to a temperature close to absolute zero, or minus 273 degrees Celsius. “For us, this ultracold ensemble represented a very promising starting point for atom interferometry,” explained Windpassinger. Temperature is one of the determining factors, because measurements can be carried out more accurately and for longer periods at lower temperatures.

Findings could help explain how air pollutants interact with the atmosphere.

Researchers at the University of British Columbia, University of California Irvine, and McGill University have discovered three liquid phases in aerosol particles, changing our understanding of air pollutants in the Earth’s atmosphere.

While aerosol particles were known to contain up to two liquid phases, the discovery of an additional liquid phase may be important to providing more accurate atmospheric models and climate predictions. The study was published recently in PNAS.

But being such effective survivors may come at a cost.

A group of Cancer Research UK-funded scientists are beginning to discover new vulnerabilities in cancer cells, which emerge when they enter “survival mode.”

Gotta catch them all because this one may cause legionnaires diesease.

“Institute of Zoology have named one of the newly discovered bacteria ‘Pokemonas’ because they live in spherical amoebae, comparable to Pokémon in the video game, which are caught in balls.”

A research team at the University of Cologne has discovered previously undescribed bacteria in amoebae that are related to Legionella and may even cause disease. The researchers from Professor Dr. Michael Bonkowski’s working group at the Institute of Zoology have named one of the newly discovered bacteria ‘Pokemonas’ because they live in spherical amoebae, comparable to Pokémon in the video game, which are caught in balls. The results of their research have been published in the journal Frontiers in Cellular and Infection Microbiology.

When you think of night-vision goggles, you probably imagine the pitch black of night being illuminated in a sea of green that helps improve visibility. That’s ancient technology now as the US Army’s Lancer Brigade of Joint Base Lewis–McChord demonstrates what soldiers see through the military’s latest and greatest night vision goggles. The Predator would be jealous.
