just another attempt to revive cold fusion from the dead ... and all with dubious experimental setups; read the last phrase ""From my perspective, this is still a physics experiment," Zawodny said. "I'm interested in understanding whether the phenomenon is real, what it's all about. Then the next step is to develop the rules for engineering. Once you have that, I'm going to let the engineers have all the fun." He went on to say that, " All we really need is that one bit of irrefutable, reproducible proof that we have a system that works. As soon as you have that, everybody is going to throw their assets at it. And then I want to buy one of these things and put it in my house."
"The forecasts were the product of a series of "summer studies" led by NASA's Ames Research Centre and Stanford University, at which top academics, scientists, and engineers gathered to imagine how future space colonies could look. Artists gave life to the blueprints, producing a stunning series of images that look like a cross between CGI real-estate models (complete with would-be residents smugly sipping wine) and the fantastical worlds of Isaac Asimov."
must look funny ...
They calculate the properties of such a metatmaterial and how it might be constructed with a basic repeating unit in the form of a concrete cylinder some 18 metres in diameter, with four perpendicular holes in its sides (see picture).
These cylinders, perhaps varying in size to absorb a range of seismic wavelengths, would need to surround the foundations of a building in cylindrical shells some 60 metres across.
That needn't be prohibitively expensive but it would be a big structure that could only be constructed around isolated buildings (thereby somewhat negating the supposed benefit that other buildings in the earthquake 'shadow' might also be protected).
VERY nice! one of the promised apps of "swarms" at last demonstrated...and i was beginning to lose hope! (pity this article goes under this "singularity" website...)
A crack team of engineers at the University of Illinois has developed an electronic circuit that autonomously self-heals when its metal wires are broken.
Progress in atomic, optical and quantum science1, 2 has led to rapid improvements in atomic clocks. At the same time, atomic clock research has helped to advance the frontiers of science, affecting both fundamental and applied research. The ability to control quantum states of individual atoms and photons is central to quantum information science and precision measurement, and optical clocks based on single ions have achieved the lowest systematic uncertainty of any frequency standard3, 4, 5. Although many-atom lattice clocks have shown advantages in measurement precision over trapped-ion clocks6, 7, their accuracy has remained 16 times worse8, 9, 10. Here we demonstrate a many-atom system that achieves an accuracy of 6.4 × 10−18, which is not only better than a single-ion-based clock, but also reduces the required measurement time by two orders of magnitude. By systematically evaluating all known sources of uncertainty, including in situ monitoring of the blackbody radiation environment, we improve the accuracy of optical lattice clocks by a factor of 22. This single clock has simultaneously achieved the best known performance in the key characteristics necessary for consideration as a primary standard-stability and accuracy. More stable and accurate atomic clocks will benefit a wide range of fields, such as the realization and distribution of SI units11, the search for time variation of fundamental constants12, clock-based geodesy13 and other precision tests of the fundamental laws of nature. This work also connects to the development of quantum sensors and many-body quantum state engineering14 (such as spin squeezing) to advance measurement precision beyond the standard quantum limit.
Neurobiologists from the University of Leicester have shown that insect limbs can move without muscles - a finding that may provide engineers with new ways to improve the control of robotic and prosthetic limbs
In a jaw-dropping feat of engineering, electronics turn a person's thoughts into commands for a drone. Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.
Engineering and improving great tits so they can better withstand climate change. By selectively breeding and genetically Engineering the birds scientists try to keep the time when the birds produce offspring in sync with the changing availability of food sources in spring (mainly grubs).
I remember that ESA was looking into similar things for the Vulcain 2/2+ NE upgrade together with Volvo and other companies. Does anybody know about the status of that program (google does not ;-))?
Engineers at NASA's Kennedy Space Center in Florida are partnering with counterparts at the agency's Goddard Space Flight Center in Maryland to develop systems to bring potential future robotic "service tow trucks" to orbiting spacecraft in need of aid
"A band of space hackers and engineers are trying to do something never done before - recover a 36 year old NASA spacecraft from the grips of deep space and time. With old NASA documents and Rockethub crowdfunding, a team led by Dennis Wingo and Keith Cowing is attempting to steer ISEE-3, later rechristened ICE, the International Cometary Explorer, back into an Earth orbit and return it to scientific operations. Dennis says, 'ISEE-3 can become a great teaching tool for future engineers and scientists helping with design and travel to Mars'. Only 40 days remain before the spacecraft will be out of range for recovery. A radio telescope is available, propulsion designs are in hand and the team is hoping for public support to provide the small amount needed to accomplish a very unique milestone in space exploration
