Astronomers have identified the final chunks of all the ordinary matter in the universe — Despite the fact that it took so long to identify it all, researchers spotted it right where they had expected it to be all along: in extensive tendrils of hot gas that span the otherwise empty chasms between galaxies, more properly known as the warm-hot intergalactic medium, or WHIM. Early indications that there might be extensive spans of effectively invisible gas between galaxies came from computer simulations done in 1998.
~ Ah, those tendrils of hot gas!
Spock’s home — In a wonderful example of truth validating fiction, the star system imagined as the location of Vulcan, Spock’s home world in Star Trek, has a planet orbiting it in real life. A team of scientists spotted the exoplanet, which is about twice the size of Earth, as part of the Dharma Planet Survey (DPS), led by University of Florida astronomer Jian Ge. It orbits HD 26965, more popularly known as 40 Eridani, a triple star system 16 light years away from the Sun. Made up of a Sun-scale orange dwarf (Eridani A), a white dwarf (Eridani B), and a red dwarf (Eridani C), this system was selected to be “Vulcan’s Sun” after Star Trek creator Gene Roddenberry consulted with astronomers Sallie Baliunas, Robert Donahue, and George Nassiopoulos about the best location for the fictional planet.

Unprecedented glow around neutron star — Neutron stars, which contain more mass than the Sun but have a radius of only a few miles, continue to be the subject of intense observation. Now, scientists have spotted one of these ultra-dense objects emitting infrared radiation far brighter than they’d expect, over a seemingly wide swath of space – larger than our Solar System. They have several ideas as to what they’re looking at, and any of these ideas, if verified, would be important discoveries.
~ My idea is that gleaming Joanna Paul stuff women used to put on their faces.
Where are we, again? The third edition of the International Celestial Reference Frame, or ICRF-3, is the most up-to-date version of the International Astronomy Union’s standardised reference frame. Imagine the universe as a graph from geometry – scientists need a place to put the origin and axes.
~ Very Long Baseline Interferometry puts us in our place.
First Hydrogen-powered train hits the tracks In Germany — French train-building company Alstom has built two hydrogen-powered trains and delivered them to Germany, where they’ll zoom along a 62-mile stretch of track that runs from the northern cities of Cuxhaven, Bremerhaven, Bremervorde, and Buxtehude,” Alstom is contracted to deliver 14 more hydrogen-powered trains, called Coradia iLint trains, before 2021.
The trains are an initial step toward lowering Germany’s transportation-related emissions, a sector that has been intractable for policy makers in the country.
~ Smart motion.
Robots to take and give jobs — The advancement of robotics and artificial intelligence will make 75 million jobs obsolete by the year 2022, according to a new report. Sounds dreadful, but the same report goes on to predict the creation of 133 million new jobs over the same period.
~ Yeah, but maybe I don’t want to be a robot-polisher!
Robot skin transforms inanimate objects — Typically, robots are built to perform a single task. To make them more adaptable, researchers from Yale University have developed a kind of ‘robotic skin’ that transforms ordinary objects into multifunctional robots.
OmniSkins is made from elastic sheets embedded with sensors and actuators. The flexible sheets can be wrapped or affixed to a soft, malleable surface, such as a stuffed animal or a foam tube. The skins then “animate” these objects by applying force to their surface, leading to distinct movements.
~ So chuck it on corpses and make zombies? Yuk!
