Researchers from Monash, Swinburne, and RMIT universities have tested the world’s fastest internet speed. The team was able to achieve a data speed of 44.2 Terabits per second (Tbps) from a single light source.
This new technology can support 1.8 million high-speed simultaneous connections, and best of all this technology can be installed into existing infrastructure. The new device known as a micro-comb replaces 80 conventional lasers with a single piece of equipment.
The future goal for the research team is to make this technology low cost and compact that it can be installed for commercial use by the general public in cities around the world.
The electronics and entertainment giant Sony has combined artificial intelligence with its image sensor. This new IMX500 sensor is the first of its kind to process images without the need for external hardware and assistance.
The new sensor features 12.3 megapixels and can handle 4K 60 fps video capture.
When it comes to security, the IMX500 shines since the chip can process a massive amount of data locally instead of sending that data to the cloud for processing. Which in turn keeps sensitive video and image data on the device itself. Since the data doesn’t need the cloud, processing times are also cut drastically.
Sony is currently shipping the IMX500 to commercial establishments for evaluation. Consumers can expect to see them sometime early next year. Something to keep in mind Sony is a huge supplier of image sensors for Apple iPhones and Nikon cameras.
Scientists from the National Renewable Energy Laboratory (NREL) have created a world record six-junction solar cell that has a conversion efficiency of 47.1%. The device is built using III-V materials which are known for a wide range of light-absorbing properties. Total the device contains 140 layers of III-V materials, with each layer design to capture a specific part of the solar spectrum.
These types of solar cells are typically used to power satellites because of there high efficiency and cost. Here on earth, the six-junction solar cell is best suited for concentrator solar panels. This type of panels cut the cost down quite a bit since you only need a fraction of the material used in conventional solar panels. Also, the efficiency increases as you concentrate the light.
The next step for the scientist is to exceed the 50% barrier and significantly reduce the cost so that these solar cells can reach new markets.
Microsoft is planning to release quite a bit of tech for this holiday season. One of the most anticipated is its new gaming console, The Xbox Series X. This beast of a system can rival many gaming PCs, and can kick out 4K gameplay with up to 120fps and is 8K ready. This is all possible thanks to AMD’s latest system on chip (SOC).
The brains of the system is a custom 8 core processor featuring AMD’s latest Zen 2 architecture. It’s able to sustain 3.8GHz (3.6 GHz for multithreaded games and apps).
When it comes to the graphics power, the Xbox Series X has 2x the power compared to the Xbox One X or 8x that of the original Xbox One. Built on AMD’s RDNA 2 architecture, the GPU feature 56 compute units and runs at 1825MHz sustained. This gives the GPU a compute power of 12 Tflops, also, the graphics processing unit has built-in Ray Tracing.
The Xbox Series X is equipped with 16GB of GDDR6 memory with a 328bit bus. It’s allocated in the following way, 10GB for the GPU, 3.5GB for standard memory task, and 2.5GB for the operating system. Storage is handled by a 1TB PCIe 4.0 SSD which has a transfer speed of 2.4GB/s Raw and 4.8GB/s compressed. There is also an external storage port in the back of the console. As of this writing, 1TB is the largest external storage available.
The new form factor of the console is not just aesthetically pleasing but is key to the cooling of the system. Inside you’ll find a dual motherboard setup with a vapor chamber cooling assembly. At the top is a custom fan that is designed to create a vortex that pulls air from the bottom up.
Other features of the Xbox Series X are quick resume which allows players to jump from game to game with very little wait time. Xbox Velocity Architecture takes old games and improves performance, resolution, as well as provide higher stable frame rates. Microsoft has also upgraded its wireless controller. The new controller has sculpted surfaces and a refined geometry for comfort, along with textured grip, a hybrid D-pad, and faster pairing.
There is no official price for the Xbox Series X yet, but given the hardware, expect to pay a premium.
Being the new normal, many of us are working from home. Unfortunately in the rush to set up our home offices, security and protection often get overlooked. The current situation has cyber-attacks on the rise which poses the risk of stolen identity, passwords, and personal information.
Recently Dell Technologies released a utility that protects the vital part of a computer system, the BIOS. The utility, called Dell SafeBIOS, relies on behavior-based threat detection to spot imminent attacks and provides a visual analysis of BIOS alterations before and during threats. System administrators can then isolate the targeted device and deploy countermeasures. Dell SafeBIOS is available for download at the Dell web site.
Some common sense things you can do to help protect yourself is keeping your anti-virus up-to-date, download the most recent security updates for your router, and your operating system.
Intel’s long-awaited answer to AMD’s Ryzen 3rd Gen processors is just around the corner. The 10th generation Comet Lake S processor is expected to be formally announced on April 30 and will feature boost speeds up to 5.3GHz. This speed boost is made possible using Intel’s Thermal Velocity Boost technology, which engages when the system has proper cooling and power available.
The processor is expected to come in three flavors, the top i9-10900K will feature 10 cores and 20 threads as well as reach 5.3GHz. According to leaked specs, the i9-10900K should perform faster than the AMD Ryzen 3700X but slower than the 3900X. The other processors will be the i7-10700K with 8 cores, 16 thread and speeds up to 5.1GHz and the i5-10600K with 6 cores, 12 threads and a top boost speed of 4.8GHz.
Intel says that these processors will have high frames rates in AAA titles, even under heavy multitasking workloads. Pricing for the i9, i7 and i5 are estimated at $550, $288 and $177.
Later this year the two giants go head to head again, with AMD planning the release of the Ryzen 4000 series processors and Intel unveiling their 11th generation processor lineup.
Neuroscientists at the University of California San Francisco have come up with an artificial intelligence program that can turn thoughts into text. The scientists conducted human trials with four participants. Each of the participants with epilepsy had electrodes implanted into their brains. Then each participant read 50 sentences aloud multiple times, including lines like “there is chaos in the kitchen.”
As each person spoke, the researchers monitored each participants brain activity and input the data into a machine learning algorithm. The algorithm converted the brain wave activity into a string of numbers that encoded the sentences. In another part of the system, the numbers were converted back into a sequence of words.
In the beginning, the system produced some strange results. Over time the system was able to improve, at one point it got 97 percent of the sentences correct.
Currently, this technology is limited to verbal speech, it has the potential to help those who have speech disabilities in the future.
Do you experience poor signal strength or slow data transfers when using Wifi? Engineers at the University of California San Diego might just make all that a thing of the past, as they have developed a “smart surface”. In testing, the smart surface extended WiFi range from 98 feet to 147 feet, as well as, doubled its speed.
This surface is a 4″ x 12″ printed circuit board containing 48 small antennas. These antennas combine incoming WiFi signals from a router to create an entirely new path for signals to travel. This new path is just as strong as the original coming from the router. This technology also creates a second data stream that goes to your connected Wifi device. Not only do you get a connection in areas where you could not before, but you also get double the data rate where you already have connectivity.
This technology has a couple unique benefits, one is it’s extremely power efficient, it can last up to a year on a coin cell battery. Second is the technology can be mass-produced for $5 each.
In future studies, the researchers plan to combine multiple smart surfaces to see if they could possibly triple or even quadruple data rates and range.
The cybersecurity organization Bitdefender reported that phishing scams related to the coronavirus have been detected on Linksys and D-Link routers. Hackers taking advantage of weak passwords change the DNS IP addresses so that instead of going to a legitimate website, the user is redirected to a malicious one.
Once the user goes to the malicious website, a pop-up window appears that says “to have the latest information and instructions about coronavirus (COVID-19).” The pop-up also claims that the information is provided by the World Health Organization. When the download button is clicked, a trojan is installed that steals sensitive information. Such as user keystrokes, passwords, emails, and financial documents.
To combat this threat, users are advised to turn off remote administration on their routers, update to strong passwords for their systems, and make sure anti-virus and anti-malware programs are up to date. Also double-check the spelling of email addresses and websites for variances from legitimate ones.
Physicists from the University of Leeds have made a breakthrough, they have created a spin capacitor that can generate and hold the spin state of electrons for several hours. This is the first time this has ever been accomplished, previous attempts have only ever held the spin state for a fraction of a second.
In electronics, a capacitor stores an electric charge. A spin capacitor not only holds a charge but also stores the spin state of a group of electrons-which basically freezes the spin position of each of the electrons.
The ability of this new capacitor makes it possible to create highly efficient storage devices. So much so that a spin capacitor measuring just one square inch could store 100 Terabytes of data.
