DARPA successfully demonstrates, transitions advanced RF networking program
A DARPA network technology program recently concluded field tests demonstrating novel software that bridges multiple disparate radio networks to enable communication between incompatible tactical radio data links - even in the presence of hostile jamming. The technology is transitioning to Naval Air Systems Command (NAVAIR) and the Marine Corps, which plans to put the software on a software repr How scientists are using declassified military photographs to analyse historical ecological change
Researchers are using Cold War spy satellite images to explore changes in the environment, including deforestation in Romania, marmot decline in Kazakhstan and ecological damage from bombs in Vietnam.
Ecologists have harnessed new advances in image processing to improve analysis of declassified US military intelligence photographs and detect previously unseen changes in the environment. Dr Weak force has strong impact on nanosheets
You have to look closely, but the hills are alive with the force of van der Walls.
Rice University scientists found that nature's ubiquitous "weak" force is sufficient to indent rigid nanosheets, extending their potential for use in nanoscale optics or catalytic systems.
Changing the shape of nanoscale particles changes their electromagnetic properties, said Matt Jones, the Norman an New fullerene crystal production method 50 times faster than predecessor
Researchers from Yokohama National University and the University of Electro-Communications in Japan have developed a highly efficient technique for producing a unique fullerene crystal, called fullerene finned-micropillar (FFMP), that is of significant use for next-generation electronics.
Fullerene is a popular choice for developing technologies not only due to its small size, it is also v Space Development Agency to reevaluate proposals for missile-tracking satellites

ESA Clean Space tackles space junk one component at a time
VALETTA, Malta — Through a novel approach to testing, the European Space Agency’s Clean Space initiative is assisting in the development of satellite components that are designed for demise, an approach to satellite development that advocates for the safe disposal of spacecraft by destructive atmospheric reentry.
Image: Space bauble produced by the Multiscale Boiling experiment
Deck the halls with space-based bubbles!
Here is a festive bauble you will not see on Earth: a bubble produced by the Multiscale Boiling experiment, known affectionately as Rubi.
In this image, electrostatic forces are pulling the bubble upwards and making it spherical, producing not only a cool image but also cool insights into the boiling process.
Understanding how boiling behaves in weightlessness is imperative because gravity plays an important role. Without gravity, boiling takes place in slow motion and produces larger bubbles. This has allowed scientists to observe and measure effects that are too fast and too small on Earth.
The experiment is also installed with an electrode to observe the effect of an electric field on the bubbles, enabling scientists to observe and quantify the effect of external forces.
"Boiling is an extremely efficient way of getting rid of excess heat. This research could therefore provide very valuable information for improving the thermal management systems in space as well as in terrestrial applications," says ESA project scientist Daniele Mangini.
With this insight and more accurate calculations of the boiling process, products such as laptops can be improved and made more compact.
