The excessive use of pesticides has brought about numerous disastrous effects on the environment, and among them, it has recently drastically reduced the bee population in various areas of the world. Yet, not many countries took remedial measures, even after realizing the dangers, but this was not the case with France.
It is on track to becoming the first European country to ban five pesticide varieties, as scientists believe that these neonicotinoids are extremely dangerous since they kill bees.
However, while bee-keepers and environmentalists are extremely happy with this decision, sugar beet and cereal farmers are not very excited about it, since they are afraid that in this way, their crops will be more prone to pests and insects.

“Complementary metal–oxide–semiconductor (CMOS) technology has provided a highly sensitive detection platform for high-resolution optical imaging, sensing and metrology. Although the detection of optical beams carrying angular momentum have been explored with nanophotonic methods, the metrology of optical angular momentum has been limited to bulk optics. We demonstrate angular-momentum nanometrology through the spatial displacement engineering of plasmonic angular momentum modes in a CMOS-compatible plasmonic topological insulator material.”
Twisted Light Could Dramatically Boost Data Rates.

“Big deal, you say? It most certainly was. The concept of orbital angular momentum (OAM) has done nothing less than inspire a reimagining of what we’re capable of doing with electromagnetic radiation. Beams that carry OAM can be used to move tiny objects, and they have been used to enhance the resolving power of microscopes.”

BEAUMONT-SUR-OISE, France (AP) — Master Yoda, dust off his French, he must.
It’s now easier than ever in France to act out “Star Wars” fantasies, because its fencing federation has borrowed from a galaxy far, far away and officially recognized lightsaber dueling as a competitive sport, granting the iconic weapon from George Lucas’ saga the same status as the foil, epee and sabre, the traditional blades used at the Olympics.
Of course, the LED-lit, rigid polycarbonate lightsaber replicas can’t slice a Sith lord in half. But they look and, with the more expensive sabers equipped with a chip in their hilt that emits a throaty electric rumble, even sound remarkably like the silver screen blades that Yoda and other characters wield in the blockbuster movies.

Stargazers will get a close-up look at Earth’s natural satellite this week thanks to the brightest supermoon event of the year.
A supermoon phenomenon occurs when a full moon, on its oval-shaped orbit, is at its closest to us, known as perigee, which is about 356,000 kilometres as measured from the centre of the Earth to the centre of the moon.
It takes place when the moon’s orbit brings it to the closest point to Earth while at the same time bathed in sunlight, giving the moon its bright appearance.

Electric cars could be charged at any time and any place.
It could reliably supply energy 99 per cent of the time, at six-times the intensity of solar farms on earth, he said.
Chinese scientists first plan to build and launch small to medium-sized solar power stations to be launched into the stratosphere to generate electricity, between 2021 and 2025.
