FIFA panels come down at Science World - CTV News

Plants are the original solar panels, and they're very good at converting light into energy – red and blue light, that is. But what if a solar panel could co-exist with plants, capturing the light that they aren't using while allowing those red and blue wavelengths through? That's what a team led by Silvia Ma Lu of Mälardalen University in Sweden has tested in a new study, using semi-transparent, rose-tinted solar panels that let specific wavelengths of light through to plants growing below, while also capturing solar energy for electricity. They've presented their prototype in the scientific journal Cell Reports Physical Science. "The basic concept is quite straightforward," Ma Lu says. "The solar panels use part of the incoming sunlight to generate renewable electricity while allowing part of the light to pass through to the crops growing underneath. "Perhaps we could be harvesting sunlight more efficiently by allocating different portions of the solar spectrum to crop growth and electricity generation, she says.

Orcas are hunting great White Sharks around the world, scientists confirmThe killing of great whites by orcas has been reported in the waters of South Africa, California, and Australia, and the implications that the hunting behaviour would have on the marine ecosystem have been considered. In fact, it all started back on May 3, 2017, when the body of a female great white, weighing 1,100 kilograms, washed ashore in Gansbaai, close to Cape Town, with a deep gash through which its 90-kilogram liver had been extracted. Five more corpses of great whites appeared with similar wounds in the coming months, as claimed by shark biologist Alison Towner of Rhodes University. Two adult males, called Port and Starboard, who are supposed to be brothers judging by their dorsal fins that fold differently, were identified as the most probable perpetrators. The connection was officially established in 2022 based on video footage of a drone that caught three orcas chasing and biting a 3-meter great white off Mossel Bay. The sharks quickly disappeared from Dyer Island, one of the best places in the world to witness a great white.
