The recent ratification of the IEEE 802.11bb standard represents a seismic shift in wireless communication, offering a new frontier that goes beyond Wi-Fi: LiFi (Light Fidelity). Utilizing infrared light instead of radio waves, this standard brings LiFi technology closer to mainstream adoption. This article delves into what this innovative standard means for various applications, including smart homes, healthcare, retail, and more.

The Core of IEEE 802.11bb

The IEEE 802.11bb standard serves as a robust framework for secure, reliable, and high-speed wireless communication. Unlike traditional LiFi that used visible light, this new standard utilizes infrared (IR) lightwaves, invisible to the human eye but highly effective for transmitting data at lightning speeds.

Wi-Fi signals can do much more than deliver streaming movies and music around the home, it turns out: they can also be used to identify shapes through solid walls, as demonstrated in recent experiments.

The ability for Wi-Fi to spot movement through walls has been shown off before, but the technology struggles with seeing anything that isn’t in motion.

To overcome that limitation, researchers from the University of California Santa Barbara (UCSB) designed a Wi-Fi setup to concentrate specifically on the edges of objects, much like a person might do an outline drawing.

Beguš is a linguist at the University of California, Berkeley. He got the chance, last summer, to observe sperm whales in their wild Caribbean habitat off the coast of the island nation of Dominica. With him were marine biologists and roboticists. There were also cryptographers and experts in other fields. All have been working together to listen to sperm whales and figure out what they might be saying.

They call this Project CETI. That’s short for Cetacean Translation Initiative (because sperm whales are a type of cetacean).


AI translates human languages with ease. Researchers are now using this tech to analyze the sounds of whales, rodents and many other animals.

HARNHAM, United Kingdom — The mysteries of Stonehenge may be the tip of the archaeological iceberg in this region of the United Kingdom. Researchers have made another remarkable discovery just miles from the world-famous site.

While preparing for a new housing development in Harnham, just eight miles south of Stonehenge, workers unearthed items that may date all the way back to 10,000 BC. The findings include ancient pottery, knives, and even red deer antler, which was often used for making tools and weapons in prehistoric times, according to archaeologists.

Cotswold Archaeology partnered with Vistry Group, the property developers, on this excavation project.

The Sentinel system facilitates extended stays underwater, allowing scientists to reside at depths of up to 200 meters for as long as 28 days.

In a bold initiative, DEEP, a leading research organization, has announced plans to construct an underwater habitat open to the public by 2027. Named Sentinel, this modular subsea abode aims to revolutionize underwater living, research, and observation by providing scientists unprecedented access to the depths of the ocean.

Rubio surpassed the U.S. space endurance record of 355 days on Monday at the International Space Station. He arrived at the outpost last September with two Russians for a routine six months. But their stay was doubled after their Soyuz capsule developed a coolant leak while parked at the space station.

The trio will return to Earth on Sept. 27 in a replacement capsule that was sent up empty for the ride home. By then, Rubio will have spent 371 days in space, more than two weeks longer than Mark Vande Hei, the previous U.S. record holder for a single spaceflight. Russian cosmonaut Valeri Polyakov holds the world record of 437 days, set in the mid-1990s.

This talk is about how you can use wireless signals and fuse them with vision and other sensing modalities through AI algorithms to give humans and robots X-ray vision to see objects hidden inside boxes or behind other object.

Tara Boroushaki is a Ph.D student at MIT. Her research focuses on fusing radio frequency (RF) sensing with vision through artificial intelligence. She designs algorithms and builds systems that leverage such fusion to enable capabilities that were not feasible before in applications spanning augmented reality, virtual reality, robotics, smart homes, and smart manufacturing. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

The Floridian repeat offender told the authorities that he planned on wheeling himself to London, England.

It started on August 26 when the US Coast Guard was transiting in the Atlantic Ocean in preparation for an intense hurricane when they found a weird-looking vessel in the middle of the ocean, 70 miles (110 km) off the coast of Georgia. There was a man aboard the vessel. He told the authorities that he planned on wheeling himself to London, England.


A Florida man was arrested in the middle of the ocean after he was found floating in a homemade vessel resembling a hamster wheel. But how did he get there in the first place?

Vessel has peddles to propel it

When the Coast Guard asked the man for registration papers, he assured the men that the vehicle was registered but was unable to produce papers. Looking closely at the vessel, the Coast Guard was able to identify home supplies like wires and buoys and deemed the vehicle unsafe for the voyage.

Lenovo’s next 27-inch 4K monitor is unlike any display it has released before. Featuring a lenticular lens and real-time eye-tracking, it’s a 3D monitor that doesn’t require any glasses. Other companies are already pushing stereoscopic products, but Lenovo’s ThinkVision 27 3D Monitor, announced at the IFA conference today, takes the glasses-free experience to a bigger screen.

The technology behind Lenovo’s 3D monitor and the accompanying software, 3D Explorer, are proprietary, a Lenovo spokesperson confirmed to Ars. 3D Explorer includes a 3D player and SDK for building 3D apps. Lenovo is targeting the monitor and app at content creators, like 3D graphic designers and developers.

Like other glasses-less 3D screens, the ThinkVision works by projecting two different images to each of your eyes, resulting in a 3D effect where, as PR images would have you believe, it appears that the images are popping out of the screen. Lenovo says the monitor’s 3D resolution is 1920×2160. The lenticular lens in the monitor is switchable, allowing for normal, 2D viewing at 3840×2160, too.

Bacteria that can align themselves with the Earth’s magnetic field have been found in a new habitat. Previously spotted on land and in shallow waters, these magnetotactic bacteria have now been confirmed to thrive in the depths of a hydrothermal vent. Despite the challenging conditions, the bacteria were able to adapt and survive in an environment that was not ideal for their typical needs.

Magnetotactic bacteria are of interest not only for the role they play in Earth’s ecosystem but also in the search for extraterrestrial life. Evidence of their existence can remain in rocks for billions of years. Their magnetic inclinations can also provide a record of how magnetic poles have shifted over time. This new discovery brings hope to researchers that the magnetic bacteria might be found in yet more unexpected locations, on Earth and perhaps even on Mars.

Mars is the second smallest planet in our solar system and the fourth planet from the sun. It is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.
