Is ‘Deltacron’ real? What is known about the possible new variant?



After a professor of biological sciences at the University of Cyprus on Saturday released what he called a “deltacron”, a possible convergence of the genetic signature of the omicron variant of the coronavirus within genomes of the delta variant, the international scientific community finds perplexed and, at the same time, cautious. Could we be facing a new variant of the virus, or is it all just a processing error in the laboratory?

THE Bloomberg reported on Saturday (8) that a Cypriot professor named Leondios Kostrikis claimed to have discovered 25 cases of coronavirus mutation. In an interview with Sigma TV the day before, the researcher revealed that “Currently there are omicron and delta co-infections, and we found this strain that is a combination of these two”. On the same day, the samples were sent to Gisaid, a database that tracks mutations of the coronavirus.

The release of the report started a small commotion on social networks, with the term “deltacron” reaching the trending topics. What people fear is that a possible genetic recombination of the highly transmissible omicron with the deadly delta could cause an unprecedented tragedy in the pandemic scenario. But soon experts arrived on the scene, claiming that perhaps the picture is not exactly what was broadcast.

What do the experts say?

One of the best-known coronavirus researchers, Imperial College London virologist Tom Peacock, took to his Twitter account to state that “Cypriot ‘deltacron’ sequences reported by several major media outlets appear to be clearly contamination.” About an alleged recombination, he explained: “Many of us have looked at the sequences and come to the same conclusion that it doesn’t look like a real recombinant.”

The World Health Organization’s (WHO) top COVID-19 authority, Krutika Kuppalli, also took to Twitter to clarify that, in the case of deltracron, there was likely “laboratory contamination of omicron fragments in a delta specimen.” In another tweet, the doctor even mocks the matter, stating: “Let’s not mix up infectious disease names, and leave it to celebrity couples.”

What can be seen is that, although Kostrikis assures that his findings do not constitute a “technical error”, many renowned experts doubt the published results. That is, until analysis proves otherwise, there is no cause for concern.

Apple becomes the world’s largest smartphone seller



If for three quarters, Samsung has been at the top of the ranking of smartphone sales, the South Korean brand will have to give way to its rival Apple. Indeed, in the fourth of the past year, iPhone sales have surpassed those of the portables marketed by Samsung.

iPhones alone made up nearly 22% of global smartphone shipments recorded in the last quarter of the past year. The information was revealed on January 18, 2022 by a report by the independent analysis company, Canalys.

Apple surfs on the good sale of the iPhone 13

Decidedly, 2021 seems to be a blessed year for Apple. A few days after breaking records in terms of capitalization, the Cupertino company has once again become the biggest seller of smartphones in the world.

According to Sanyam Chausaria, an analyst at Canalys, the bitten apple brand has benefited from the enthusiasm generated by the iPhone 13. Launched last September, Apple’s latest flagship product experienced strong demand between October and December.

Particularly in mainland China, where the iPhone 13 has been a big sales hit. It must be admitted that Apple had planned for it by implementing an aggressive pricing strategy for its flagship products, including the iPhone 13.

This allowed him to recover the first place at Samsung with an estimated market share of 22%. The South Korean brand does not have to be ashamed of its performance, however. It is just behind Apple with a market share estimated at 20%.

The top 5 is completed by three Chinese brands, namely: Xiaomi, Oppo and Vivo. They concentrate, for their part, 29% of the market share with 12% for Xiaomi.

Apple limited in its performance by shortages of key components

Apple certainly sold a lot of smartphones in the fourth quarter of 2021. However, its sales performance could have been more consistent. Indeed, the firm was forced to reduce its production at one time because of a break in its supply chain of essential components.

This did not allow it to manufacture enough smartphones to meet demand. According to Canalys, the constraints linked to the supply chain will have cost the Cupertino company the tidy sum of 6 billion dollars. However, it has made every effort to best meet the demands of priority markets, with appropriate delivery times.

Apple isn’t the only manufacturer that has been impacted by supply chain issues. This is a situation that has affected all suppliers without exception. The industry is not expected to regain its stride until the second half of 2022, according to estimates. Perhaps not for Apple, which has indicated that its supply chain is now fully restored.

WiFi 7 already flies at speeds of 30 Gbps and has an arrival date



Although it seemed that the names of WiFi were going to be simplified, since WiFi 6 we have known the announcement of three new wireless connectivity standards: Wi-Fi 6E, Wi-Fi 6 Release 2, and Wi-Fi 7. With WiFi 6E we can use the 6 GHz frequency, while with WiFi 6 Release 2 we have improvements in MU-MIMO to better support the load when many users are connected, as well as reducing energy consumption. However, the big jump we are going to see with Wi-Fi 7.

The Wi-Fi 7 standard (802.11be) is not even finalized yet by the Wi-Fi Alliance, but there are already manufacturers who are thoroughly testing it. MediaTek has been the first of all that has managed to make the new standard work in a real environment. And the speeds it reaches are spectacular.

Up to 30 Gbps speed with WiFi 7

With WiFi 5, the maximum speed was 3.5 Gbps, while with WiFi 6 the speed went up to 9.6 Gbps. Now, WiFi 7 will allow us to reach spectacular speeds of up to 30Gbps. These figures cannot be reached with a single device, but can be reached in aggregate with several devices connected at the same time. MediaTek claims to have already reached 23 Gbps in the first real tests, but that number will increase soon.

However, there are quite a few improvements for devices that connect individually, as they will be able to achieve higher speeds thanks to the more efficient use of the standard and be able to use all available bands at the same time. MediaTek affirms that this standard will be key in the establishment of the 4K and 8K at home, which need a high bandwidth to be seen without jerks if we are watching content with a high bitrate.

MediaTek is already working with manufacturers, and will be among the first to have Wi-Fi 7 chip. Currently, the company equips its chips in laptops, routers, televisions, cameras, routers and a multitude of Internet of things devices.

Twice as wide channels and better QAM modulation

MediaTek highlights that WiFi 7 offers a multitude of advances with respect to the different iterations of WiFi 6. To begin with, we find improvements in QAM modulation (up to 4096-QAM) to more efficiently take advantage of andl available bandwidth. There are also functions like multi-link operation (MLO), where the same device can connect to several channels at the same time to transmit packets through the fastest and least congested route, also opening the door to simultaneous connections between different access points.

With WiFi 7 it will also be possible to use 320MHz channels, compared to 160 MHz of WiFi 6. The number of antennas that each router can use will be the same.

As the standard is not yet finalized, it is difficult to estimate when the first routers and devices compatible with WiFi 7 will arrive. However, MediaTek states that the first devices will be available for 2023, so in just one year we will be able to enjoy the best wireless standard. Thus, if you are thinking of renewing your network, it might be better to wait until 2023 if you want to have a home prepared for the future.
