A team of researchers has captured high-speed footage of a light pulse traveling in three dimensions as it bounced off of a series of mirrors [1]. Previous efforts have only recorded pulses moving in 2D. The team’s achievement was made possible by a new high-resolution, high-speed camera. The demonstration shows the emerging capabilities of high-speed image sensors and hints at potential applications in technologies such as time-resolved medical imaging and car safety feat
In Berlin, boudoir brand Womanizer has launched a renewable and biodegradable adult toy line called Premium Eco. Developed in partnership with British singer/songwriter Lily Allen, the toy is made from the corn starch-based biopolymer biolene. Womanizer also launched a $20,000 kickstarter, the proceeds of which will go to the nonprofit One Tree Planted. “The Womanizer […]
Geological parks: a catalyst for economic growth
Pakistan has the advantage of being a central point in the world’s geological history
The writer is a civil servant holding a PhD
The PM has recently announced the establishment of two new high altitude national parks in Gilgit-Baltistan. However, the geological history of the areas adjoining these parks and their hidden potential to aggrandise Pakistan’s economic growth remain highly under-investigated. Economic growth is not necessarily created by fixed parameters of growth in developing countries. Rather, it needs to be sustainable based on demand-led policy advice and innovative ideas. In July 2020, the International Growth Centre published a book,

Abstract:
An international research team lead by Aalto University has found a new and simple route to break the reciprocity law in the electromagnetic world, by changing material properties periodically in time. The breakthrough could help to create efficient nonreciprocal devices, such as compact isolators and circulators, that are needed for the next generation of microwave and optical communications systems.
