Researchers at Princeton University have developed an ultracompact camera, the size of a grain of salt that can produce full-color images. Just about 0.5 mm wide, the camera uses new technology called metasurface - with 1.6 million cylindrical posts.
The overall camera system makes use of hardware combined with sophisticated software to produce images. This camera, so tiny, is likely to find immediate use in invasive endoscopy and medical robots to diagnose and treat diseases.

Japanese engineers have achieved 319 Tb/s data transfer speed. For reference, it'd download 80,000 movies in a second. Researchers developed a 4-core experimental optical fiber and fired laser pulses at different wavelengths and multiple amplification techniques.
The 319 Tb/s speed was achieved over 1800 miles. Don't expect it to make it to your homes; but be assured that engineers are already preparing for 6G and the 7G.

How about paying a monthly fee to rent a grandkid who'll treat you as their own grandpa or grandma? Let's call it GaaS; and it's a reality. GoodFellows, a startup by Shantanu Naidu, who works as Ratan Tata's business assistant is currently beta-testing the concept; and it's working good.
GoodFellows participants are vetted using psychometric tests and paired. The startup aims to solve the problem of loneliness among elderly. It also aims to provide fulfilling and purposeful employment to young graduates. Interesting startup, right?

SpinLaunch is designing a novel mechanism of launching satellites into space without rockets. SpinLaunch's Orbital Accelerator spins up the satellites inside a vacuum chamber to about 5000 mph prior to launching it into atmosphere. Company promises 4x reduction in fuel and overall 10x reduction in cost.
After its first successful test-launch in October 2021, the company plans to offer commercial launches in 2024.

Apple's just made a key hire - Christopher "CJ" Moore, the director of Autopilot Software at Tesla since 2019. Moore will report to Stuart Bowers - who was the head of Autopilot at Tesla until 2019. Apple's been tight-lipped about its plans to develop automobile. There's no clarity on how long it will be before we'll see Apple's iCar. We promise to keep you posted.
