Scientists with the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers said the method demonstrates great promise; the dots are already as efficient as existing conventional methods, even though the experiments are still in early stages.

The dots could someday form the basis of infrared lasers as well as small and cost-effective sensors, such as those used in exhaust emissions tests or breathalyzers.

“Right now the performance for these dots is close to existing commercial infrared light sources, and we have reason to believe we could significantly improve that,” said Philippe Guyot-Sionnest, a professor of physics and chemistry at the University of Chicago, member of the James Frank Institute, and one of three authors on the paper published in Nature Photonics. “We’re very excited for the possibilities.”

The patented product, an AR windshield, utilizes a range of sensors such as visible light cameras and infrared cameras to create a 3D picture of the world.

Federal agencies will send the alerts on Oct. 4 to ensure that the country is prepared to inform the public in the event of a large-scale emergency.

Microsoft will drop support for the Cortana app in Windows before the end of this year, but it may be working on a new digital assistant for wearables. The company has filed a patent application for an AI-powered smart backpack.

The proposed backpack would have a camera, microphone and other sensors to collect visual and audio data from the surroundings. It could then use this contextual data to complete voice commands given by the user.

According to the patent filing, the backpack could provide navigation assistance, add calendar events, compare prices while shopping, and more. It would access the user’s data to help provide relevant information.

Sensors can detect bacteria and viruses, toxins, or other contaminants.

Samsung is the world’s biggest memory chip maker, and the company consistently keeps pushing the boundaries of technology to bring cutting-edge memory products. This time, however, the tech giant has outdone itself by developing a 256TB SSD. Yes, you’ve read it correctly. This is the first 256TB SSD in the industry, and Samsung has teased the latest product at Flash Memory Summit (FMS) 2023 in California, USA.

Samsung announces the world’s first 256TB SSD

As you might imagine, Samsung is aiming this 256TB SSD primarily at hyper-scale data centers. According to Samsung, it uses the 3D QLC NAND technology and consumes approximately seven times less power than stacking eight 32TB SSDs. The tech giant hasn’t revealed any other details about this flash drive. However, considering that it is made for data centers, it most likely has an ESDFF or NGSFF form factor.

The Maui fire. What happened. Many are pointing fingers at Hawian electric with many videos of downed powerlines. There is video taken at the Maui Bird Conservation Center in Makawao appears to show a power pole faulting just before 11 p.m. If Hawai electric turned of power when the winds were very strong there might have been a different scenario. Hundreds of kilometers to the south, Hurricane Dora was moving across the Pacific. On Maui, the wind blew, stronger than is usual for hurricanes on the island. The power then fails. Maui’s first reported wildfire last week may have been caused by damaged power lines, according to newly released research conducted by a power monitoring company. Bob… More.

Videos showing downed power lines apparently sparking some of the early blazes in Maui have become key evidence in search for cause.
