Stanford particle accelerator delivered smaller than grain of rice

The U.S. Department of Energy, with the help of researchers at Stanford University and other public and private institutions, have demonstrated the ability of a chip no larger than a grain of rice to accelerate particles 10 times faster than a conventional particle accelerator can do alone. The chip, which is specially nano-fabricated of fused silica, has the potential to drastically scale down the machinery necessary for particle research, security scanners, medical devices and other technology. The global effect of this advance could be just as revolutionary as silicon was.

However, it may take some time before scientists can collect and snap together all the puzzle pieces of this technology. Although the specially ridged inner channel of the chip can intensify by many factors the energy of a particle in the later stages of acceleration, a conventional particle accelerator (such as the Large Hadron Collider, Fermilab or CERN of dubious “God particle” fame) is still needed to get the particle up to speed in the first place.

But even here, science may have serendipitously shaken hands with itself. Researchers at the Max Planck Institute of Quantum Optics in Garching, Germany have concurrently reported some success in accelerating low-energy electrons using laser light. This could signal a marked change in the workaday humdrum of the advanced quantum mechanics world, as current research facilities rely on microwaves, which are far less energy efficient than lasers.

The Department of Energy is the single largest funder of the physical sciences in the U.S. Its research on this project, the results of which first appeared in Nature, is additionally supported by Defense Advanced Research Projects Agency’s (DARPA) Advanced X-Ray Integrated Sources (AXiS) program, the University of California at Los Angeles, and Tech-X Corp.

iPad (2022) and iPad Pro with M2 announced

Apple has announced their latest iteration of the iPad (entry level model) and the iPad Pro lineup with the new M2 processor. The event, held on the 18th of October as a recorded session displayed the key features of the iPads with the most significant being the base model iPad which has now received an upgrade. iPad 2022 This model of the base model iPad ditches the almost 12 year old home button and display layout and goes for a cleaner display only design found on the iPad Air . The chassis, which now comes with flatter sides and a TouchID fingerprint sensor on the top has also abandoned the lightning port in favor of USB C and it also comes with a set of pogo style connectors for accessories including a keyboard with trackpad. Internally, the iPad comes either as a Wifi only (Wifi6) and a 5G cellular model and is offered with 64 or 256GB of storage. The processor has also been upgraded to the Apple A14 which is the same found on the iPhone 12 series and last year's iPad Air. L

Google Pixel 7 and Pixel 7 pro along with Pixel watch unveiled.

Google announced their latest Pixel 7 and Pixel 7 Pro smartphones along with the Pixel Watch - google's first wearable at a special launch event today. The devices, which are powered by Google's second generation Tensor SOC bring major improvements in photography which has always been Google's highlight. Google Pixel 7 and Pixel 7 Pro. Google's Pixel 7 and the Pixel 7 Pro are Google's latest flagship phones for 2022. The devices, which have been developed around the Tensor G2 - Google's second generation processor developed on a 4nm architecture. The chipset, which consists of 2 Cortex X1 cores, 2 Cortex A78 cores and 4 Cortex A55 cores with a Mali G710 MC10 GPU cores and the chip is paired with 8GB of RAM for the Pixel 7 and 12GB RAM for the Pro variant. Both models come with 128 / 256GB of UFS 3.1 storage and the pro model comes with 512GB. The phones, which come with two different display sizes consist of a 6.3" 2400x1080 AMOLED display with 90Hz refre

Nikon D850 is official

Nikon D850 has probably been the company's worst kept secret . The camera , which was announced a month back during Nikon's 100 year anniversary just explained in brief ,but thanks to leakers some of that information managed to hit the internet and inadvertently lead the camera to be the most talked about topic in the camera world . But now , after a month of waiting anxiously for the official pricing (rumors made headlines after many quoted $1000-2000 more than the official one ) , the Nikon D850 is finally official . Nikon D850 The Nikon D850 is Nikon's jack of all trades semi - flagship camera which sits below the D5 but above the D750 . The model which succeeds the D810 from almost 3 years back is armed with a new backlit 35mm sensor and the largest optical viewfinder and pentaprism for any camera . Video features on the camera include 4K with full sensor readout and features 8K timelapse . The camera features 7 fps at full resolution and 9fps when connecte
