Xiaomi 80W wireless charging technology goes official

Chinese technology company Xiaomi has announced its next salvo in the fast charging wars, a new 80W wireless method that the company claims beats out any other competitor. The 80W solution is said to be able to charge a 4,000mAh battery up to 50 percent full in eight minutes and 100 percent full in 19 minutes. The video above shows it in action on a modified Mi 10 Pro.

Xiaomi already has the fastest wireless charging on a shipping phone; the Mi 10 Ultra has 50W wireless technology that can fully charge its 4,500mAh battery in 40 minutes. Oppo recently announced a 65W solution that is said to be able to charge a 4,000mAh battery in 30 minutes, but the tech is yet to ship in a commercial device.

Fast wireless charging is much less common outside China, where companies like Huawei and Xiaomi have been working to outdo each other for a while. The fastest option that’s widely available in the West is the OnePlus 8 Pro, which has an optional 30W wireless charger. Apple’s new MagSafe chargers for the iPhone 12 line charge at up to 15W.Xiaomi hasn’t announced when a phone with 80W wireless charging will actually ship, but it shouldn’t be too far off. The company has consistently released phones with ever-higher wireless power specs over the past couple of years, with the Mi 10 Ultra only coming out a couple of months ago. Source: https://www.daily-bangladesh.com

Google launches strong encryption for Android messages

Google said Thursday it will be rolling out end-to-end encryption for Android users, making it harder for anyone, including law enforcement, to read the content of messages.

“End-to-end encryption ensures that no one, including Google and third parties, can read the content of your messages as they travel between your phone and the phone of the person you’re messaging,” said Drew Rowny, head of Google product, in announcing the rollout.

Google’s move is part of an upgrade from SMS to the Rich Communication Services (RCS) standard with additional features for images and videos.

It will be available for people communicating using Android-powered devices.

The move brings additional privacy and security to Google’s messaging application, however, law enforcement agencies around the world complained that “strong encryption may enable criminals to hide their tracks”.

Digital rights activists have long supported strong encryption to allow users to avoid snooping by governments and cybercriminals. But some governments have warned the technology could hinder criminal investigations.

End-to-end encryption is already available on some services such as Facebook-owned WhatsApp, but the company has been facing resistance over its plan to bring full encryption to its Messenger app.

Last year, US Attorney General William Barr joined with British and Australian counterparts in urging Facebook to abandon its encryption, claiming the planned court hurt investigations into child exploitation.

Civil liberties groups countered that a lack of encryption or privileged access for law enforcement could hurt privacy and security for all internet users, creating holes that could be exploited by bad actors.Source: AFP, Tech Xplore Source: https://www.daily-bangladesh.com

Apple bringing 5G to the MacBook

Apple has begun working on its first cellular modem to bring 5G to its growing system-on-chip components, a new report from Bloomberg claims. However, it will bring 5G to the MacBook and due to this modem, the battery consumption will be much higher than usual.

Johnny Srozy, Apple's senior vice president of hardware technology, has confirmed the development of that 5G modem, saying “kicked off the development of our first internal cellular modem which will enable another key strategic transition.” 

Intel has been working on making Five-G modems for the last few years, however, they did not succeed in the project of making modems. Qualcomm also had problems with the device overheating and battery consumption when it first built the Five-G modem.It has not been yet known when Apple will be able to bring MacBook with Five-G modem, it’s probably going to take a while to implement. Source: https://www.daily-bangladesh.com

Scientists decode how coronavirus interacts with proteins in human cells


DEC 26, 2020 BOSTON: Scientists have charted the first atlas showing how the genetic material of the novel coronavirus interacts with the proteins in human cells, an advance which may provide a starting point for the development of new treatments against COVID-19. According to the researchers, including those from Broad Institute in the US, one of the most urgent tasks is to understand all the molecular interactions between the virus and the cells it infects. They explained that a detailed understanding of these interactions will help identify the processes in host cells which favour the multiplication of the virus, and the ones which activate the host immune system. While the SARS-CoV-2 virus uses host proteins to replicate, the scientists said until now, there has been no detailed understanding of all the proteins occurring in human cells which interact with the viral genetic material -- its RNA. In the current research, published in the journal Nature Microbiology, the scientists created the first global atlas of direct interactions between the SARS-CoV-2 RNA and the proteins present in human cells. Based on the findings, the researchers also identified important regulators of viral replication. The scientists infected human cells with the novel coronavirus, purified the viral RNA and identified the proteins bound to it. "In this particular case, we were able to perform quantitative measurements to identify the strongest specific binding partners," said study co-author Mathias Munschauer from the Helmholtz Institute for RNA-based Infection Research (HIRI) in Germany. The scientists said the atlas of RNA-protein interactions offers unique insights into SARS-CoV-2 infections, enabling the systematic breakdown of factors influencing the replication of the virus, and host defense strategies -- a crucial prerequisite for the development of new therapeutics. From the results, the scientists identified 18 host proteins that play an important role during SARS-CoV-2 infection, and found 20 small molecules that may inhibit these proteins. They believe the two proteins CNBP and LARP1 are particularly interesting. The researchers also identified target sites in these proteins that could be used to inhibit the replication of the virus. According to Munschauer, the characterization of LARP1 as an antiviral factor is a major finding. "The way LARP1 binds to viral RNA is very interesting, because it is similar to the way LARP1 regulates certain cellular messenger RNAs that we already know. This in turn provides insights into possible mechanisms of action," he added. According to the scientists, three out of four small molecules they tested inhibited viral replication in different human cell types -- findings that may open up new ways to treat COVID-19.

Scientists evaluate various mask protection, modifications against COVID-19


DEC 12, 2020 NEW YORK: Scientists have assessed the filtering efficiency provided by various types of facemask modifications, and found that masks made of two layers of woven nylon are some of the most effective when fit snug against the wearer's face. The scientists, including those from the University of North Carolina (UNC) School of Medicine in the US, noted that over the course of the COVID-19 pandemic, there have been a number of innovative "hacks," devices, and mask enhancements that claim to improve the performance of conventional masks. However, they believe there have been few evaluations of the efficiency of these face coverings or mask enhancements at filtering airborne particles. In the study, published in the journal JAMA Internal Medicine, the scientists assessed the protectiveness of various kinds of consumer-grade and modified masks, assuming the mask wearer was exposed to the virus. According to the researchers, surgical masks offered 38.5 per cent filtration efficacy, but when the ear loops were tied in a specific way to tighten the fit, the efficacy improved to 60.3 per cent. When a layer of nylon was added, they said these masks offered 80 per cent effectiveness. "Limiting the amount of virus is important because the more viral particles we're exposed to, the more likely it is we will get sick and potentially severely ill," said Emily Sickbert-Bennett, another co-author of the study from UNC. The study found that cotton bandanas folded and worn as "bandit style masks" were only 49 per cent effective, whereas N95 respirators were 98 per cent protective. According to the researchers, the presence of nose bridges, and the washing of cotton and nylon masks, significantly improved their protectiveness. "While modifications to surgical masks can enhance the filtering capabilities and reduce inhalation of airborne particles by improving the fit of the mask, we demonstrated that the fitted filtration efficiencies of many consumer-grade masks were nearly equivalent to or better than surgical masks," said study co-first author Phillip Clapp from the UNC School of Medicine.
