Visits to the dentist are usually cumbersome and expensive, but the latest development from a team of engineers, dentists and biologists from the University of Pennsylvania have designed a crew of microrobots that can be deployed and controlled to remove the buildup of plaque between the teeth and gums. That is right, scraping and scratching with mechanical tools is not the only methods via which dental clean-ups can be performed.
The scientists have developed two different types of robotic systems for entirely varied purposes. One of them works on open surfaces, whereas the other system is designed specifically to operate inside closed spaces. The researchers showcased the microrobots’ ability to destroy biofilms and sticky deposits of bacteria. Plus, the scientists state that the same technology can be implemented in cleaning dirty water pipes and other inaccessible areas which are prone to bacterial deposits.
About The Research Process
The research was led by Hyun (Michel) Koo of the School of Dental Medicine and Edward Steager of the School of Engineering and Applied Science. As per their statements, multiple biomedical fields face the issue of microbial deposits in inaccessible places. And this problem gets enhanced when the action has to be taken on human teeth, simply because it requires more precision and manual labour at the same time.

Biofilms are extremely difficult to remove from a surface, owing to their chemical composition. Previously, multiple attempts have been made to devise chemicals that can remove such deposits with relative ease, but in vain. The sticky matrix holding the bacteria against the surface provides protection from antimicrobial agents. The microrobots designed by the researchers, however, break down the biofilm matrix by working catalytically on the material with the help of iron-oxide-containing nanoparticles. The particles then activate hydrogen peroxide to release free radicals that can destroy bacterial biofilms.
The design of the 3D printed microscope is based on digital holographic microscopy. Bahram claims that the images produced by the portable microscope are almost twice the resolution of the images produced by traditional microscopy. The applications of such a device are not limited to research and medical science, rather, it can be used in defence and education as well. Since the entire microscope is manufactured out of 3D printed parts, it can be assembled anywhere and with relative ease. Moreover, unlike other scientific equipment, the 3D printed microscope is not expensive at all. Also, the incorporation of alternative components such as image sensors could drastically reduce the price point of the microscope when/if it is mass produced at some point. 
The core of the new microscope works in similar ways to a traditional digital holographic ones, where a digital camera captures the hologram generated when the light coming from the sample object interferes or colludes with the reference light wave. This process relies on a controlled setup where the environment has to be free of vibrations and temperature fluctuations. Instead, the newly manufactured equipment combines the two images using a super-resolution technique, which is scientifically referred to as Structured Illumination Microscopy. In this process, a structured light pattern is created with the help of a clear disc.

The Japanese manufacturer previously revealed information regarding some features of the upcoming console. For instance, the PlayStation 5 is expected to sport 3D audio technology, which will enable gamers to have an immersive gaming experience. Another speculated feature of the PS5 is the incorporation of a Solid State Drive or an SSD. This will lead to visibly faster game load times and seamless switching between various applications within the console’s interface. 
The Sony PlayStation 5 is expected to be the first console to sport 8K resolution gaming. Of course, to take full advantage of the same, gamers will need to plug in their console to an 8K supported panel, but Sony making a move for future-proof gaming will surely be appreciated. Last but not the least, some new PS5 games may support Ray Tracing. Ray Tracing simulates the interaction of real world light with real time objects in the game, which leads to lifelike graphic rendering. Battlefield 5 was the first game to support Ray Tracing on NIVIDA RTX powered PCs, and we can expect developers to release more titles in accordance with Ray Tracing technology if consoles start supporting it too.

First leaked on April 24 by a Dutch website, the roadmap highlights Intel’s key plans over the next two years. As per the roadmap, the company will launch a whole new refreshed lineup of Coffee Lake CPUs in the latter half of 2019. Intel will then follow up the Coffee Lake processors with the Comet Lake series of processors in the early half of the year 2020. Since Intel often labels its desktop processors as the “S-series”, it’s clearly visible in the roadmap that Intel will keep working on 14-nm S-series processors until 2022. 
Another highlighting fact is that the company has marked its upcoming 10nm “Tiger Lake” processors as TBD, or To Be Decided. Tiger Lake architecture-based CPUs will be released as the “U-series”, and they will be specifically targeted towards mobile devices such as laptops. Planned for release somewhere in the second quarter of the year 2021, the TBD label on the aforementioned CPUs may mean that the company might have different plans for them.

One of the biggest challenges while delivering drugs via nanoparticles is the exit strategy of the robots, implying that the micro robots can escape the blood vessels and accumulate in the desired spot for removal from the human body. Sangeeta Bhatia, a senior author of the aforementioned study states that it is tough to get the nanomaterials to the tissue in the lining of the blood vessel, but the use of magnetism to develop fluid forces, the nanoparticles can be pushed through the lining. The same study further states that swarms of naturally magnetic bacteria (Magnetotactic bacteria) can be also used to achieve the same result.
Schurele, the assistant professor at the Swiss Federal Institute of Technology previously worked on magnetic microbots, and consequently she aimed towards making the nanoparticle drug delivery technique more efficient when she started working with Sangeeta Bhatia. The researchers used their micro robots to target diseased sites in the human body which were usually a host of tumours. Since they faced issues with the same, the team explored their options with magnetic bacteria to devise a method to push the particles to the target in a better way.

Since the beginning, gamers have been confused regarding their monitors. Should it sport an IPS panel, or should it feature a high refresh rate for a smoother gaming experience? The ASUS PG279Q features a 27-inch IPS panel with a resolution of 2560 x 1440 px, but at the same time, the monitor sports a refresh rate of 144Hz (which is further overclockable to 165Hz), making it a “best-of-both-worlds” experience. Furthermore, the monitor features G-Sync, which allows you to switch between your refresh rates only if you are using an NVIDIA graphics card. However, the monitor is slightly expensive, and it will set you back by US$ 800 or INR 83,999. 
The Acer Predator X27 is a fantastic gaming monitor, which suffers a bit owing just to the price of the same. The monitor features an IPS panel, which is topped out a refresh rate of 144Hz. It supports 4K video playback, and a resolution of 3840 x 2160 px. The monitor supports VisionCare technology, which claims to reduce eye strain during long gameplay sessions. Moreover, G-Sync allows for a variable refresh rate in the monitor, making it the perfect fit for NVIDIA’s graphics cards. The Acer Predator X27 has a multitude of ports on both sides, including a total of 4 USB 3.0 ports as well as an HDMI 2.0 and DisplayPort 1.4. The real downside is the price, which tunes in at around US$ 2,000 (~INR 1,40,000), making it one of the most expensive gaming monitors in this list. 
Few monitors in this list cater to just eSports players, and AOC AG273QCG is definitely one of them.The monitor ticks all the boxes if you’re are an avid eSports player and need a professional grade monitor to play on. It has a 27-inch screen with 1440p resolution and on top of that, it supports NVIDIA G-Sync in one variant and AMD FreeSync in the other. The monitor has a curved design and features a high refresh rate of 165Hz. Furthermore, AOC AG273QCG has a vibrance scale that has received rave reviews from a lot of users, making it the perfect pick if you’re into that thing.
As per reports, the Samsung Galaxy Fit-e was previously supposed to be launched on May 21 in the United States, hence the fitness tracking suddenly appearing on Samsung’s Albanian website is probably a mistake. Moreover, the fact that the buying links on the website are not functioning at all gives a confirmation of sorts that this page may not be intended after all. 
Nonetheless, the listed specifications of the Galaxy Fit-e informs that the fitness band runs on the FreeRTOS operating system. It features a monochrome PMOLED display panel, which is expected out of an aggressively priced fitness band. It sports Bluetooth v5.0, and packs a 70 mAh battery which enables the Fit-e to last an entire week, the company claims. It measures at 40.2 x 16 mm and weighs 15 grams.

Dr. Niklas Mattsson, the physician at Skåne University Hospital and the lead author of the aforementioned study stated that a protein called neurofilament light in the blood can be conveniently used to measure brain cell damage in various stages of Alzheimer’s disease. The protein leaks/spills out of damaged and dying nerve cells and travels into the cerebrospinal fluid, heading into the bloodstream shortly afterwards. As per previous studies, people who suffer from diseases like Alzheimer’s have a higher level of neurofilament light in the blood.

As per noted analyst Ming-Chi Kuo, Apple will unveil a total of two iPad Pros in 2019, which will include an 11-inch variant and a second variant with a large 12.9-inch screen. This is not exactly surprising, since Apple always releases two iPad Pros every year, but the elephant in the room is the fact that Apple is planning to incorporate 5G modems in the future iPads, which will be released by early 2021 or late 2020. Yes, that’s a long way to go, especially since

When the rubber material is exposed to a source of heat, a chemical reaction occurs that enables the atoms of the material to fuse back together. The healing speed is directly proportional to the amount of heat provided to the material, the report states. However, the healing process can occur at room temperature too. It will just take more time.
