A team of amateur archaeologists have managed to find an old Roman road in the northwest countryside of England. The road has been discovered using the maps made available by the Environment Agency (EA). The maps, which are used to determine the risk of floods in areas, are developed through laser scanners fitted over the aircraft.
A US laboratory has begun printing high-temperature, high-strength 3D ceramic parts, and the development is likely to have noteworthy benefits for aviation. Californian company HRL Laboratories has used a 3D printed resin in the required size and shape, and fired it to convert it into a ceramic that can endure temperatures up to 1,700 degrees Celsius, without any loss of crucial strength.
A new technique termed as autocorrelation function timescale technique can calculate gravity on surface of distant stars with an accuracy of four percent. Scientists from University of British Columbia, University of Vienna, Australia, France and Germany have worked on a collaborative project to develop a new method of calculating gravitational pull for distant stars.
The annual Quadrantid meteor shower that is expected to peak in the pre-dawn hours on January 4 would be the first celestial event to be seen in the New Year. And scientists have suggested that those wanting to have the best view should observe the event from midnight and on through to sunrise on Monday morning.
