During power outages, microgrids leverage local renewable sources like rooftop solar panels and small wind turbines for efficient power restoration.

Addressing this common challenge, a research team from the University of California — Santa Cruz led by assistant professor Yu Zhang is employing innovative methods to enhance power systems’ efficiency, dependability, and robustness. For this, they have devised an artificial intelligence (AI) centered strategy to intelligently manage microgrids intelligently, ensuring effective power restoration in the event of outages.

The company says that the device can help users work, create, and explore in their dreams.

Prophetic, founded in March this year, has created a headpiece called the “Halo” that can induce a state of lucid dreaming. Lucid dreaming is when you are aware that you are dreaming and can manipulate the content of your dreams. Prophetic says that using the Halo can turn your dreams into a virtual workspace where you can do anything you want.

An earthquake of at least magnitude 7.5 struck Mindanao in the southern Philippines late on Saturday, triggering evacuation orders for some areas of the country and for south-west Japan over warnings of tsunami waves of 1 metre (3ft) or more.

The Philippine Seismology Agency, Phivolcs, said the waves could hit the Philippines by midnight local time (4pm GMT) and continue for hours, though there were no initial reports of significant wave damage by that time.

In the age of rapid technological advancements, a new player has emerged on the scene, promising to revolutionize the way we transmit data wirelessly. Li-Fi, or Light Fidelity, is a cutting-edge technology that employs visible light to transmit information, offering an innovative alternative to traditional radio frequency-based wireless communication systems.

The IEEE published the 802.11bb standard for light-based networking in July 2023, an extension of the Wi-Fi specification enabling wireless networking using visible and infrared light rather than the radio spectrum. The standard outlines adjustments to the physical and medium access control layers, allowing wireless networking through light source modulation imperceptible to the human eye.

The Li-Fi specification mandates bidirectional transmission within the 800nm to 1,000nm electromagnetic spectrum range, ensuring a minimum throughput of 10 Mb/s and a maximum of 9.6 Gb/s at the MAC data service access point. By comparison, Wi-Fi operates within wavelengths of 120mm (2.4 GHz) and 60mm (5 GHz), with speeds that vary across versions, including Wi-Fi 6, which reaches up to 9.6 Gb/s, akin to Li-Fi capabilities.
