While you may be just starting to reap the advantages of 5G wireless technology, researchers throughout the world are already working hard on the future: 6G. One of the most promising breakthroughs in 6G telecommunications is the possibility of Visible Light Communication (VLC), which is like a wireless version of fiberoptics, using flashes of light to transmit information. Now, a team has announced that they have invented a low-cost, innovative way to harvest the waste energy from VLC by using the human body as an antenna. This waste energy can be recycled to power an array of wearable devices, or even, perhaps, larger electronics.

Creating smart sensors to embed in our everyday objects and environments for the Internet of Things (IoT) would vastly improve daily life -- but requires trillions of such small devices. A professor believes that emerging alternative semiconductors that are printable, low-cost and eco-friendly could lead the way to a cheaper and more sustainable IoT.

A team of engineers and neuroscientists has demonstrated for the first time that human brain organoids implanted in mice have established functional connectivity to the animals' cortex and responded to external sensory stimuli. The implanted organoids reacted to visual stimuli in the same way as surrounding tissues, an observation that researchers were able to make in real time over several months thanks to an innovative experimental setup that combines transparent graphene microelectrode arrays and two-photon imaging.

Marvel at the tiny nanoscale structures emerging from labs, and it's easy to imagine you're browsing a catalog of the world's smallest pottery: itty-bitty vases, bowls, and spheres. But instead of making them from clay, the researchers designed these objects out of threadlike molecules of DNA, bent and folded into complex three-dimensional objects. These creations demonstrate the possibilities of a new open-source software program.

Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent's plants and wildlife by the year 2100, according to a new study.

Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration.
