WhatsApp Introduces Biometric Authentication for Its Desktop App and Web Browserb

WhatsApp added biometric authentication for the phones to ensure there are no security issues and user’s private messages and data are secure. The move was appreciated by the users who liked the extra privacy protection option. As the changes were positively received by most users, WhatsApp had decided to launch the same biometric authentication options for logging in to the desktop app as well. But there was no official announcement on when those changes will be introduced.

WhatsApp now has come up with an extra biometric authentication step for users who want to link their WhatsApp account to a computer’s web browser or desktop app which will make the entire process a bit more secure. Users who have enabled the biometric authentication on their phones will be required to unlock the app on their devices before they can link their account.

The new system will ensure that no one can link someone else’s WhatsApp to their web browser. It will protect user data from being accessed by someone else. WhatsApp users don’t need to do anything the new system will be enabled by default on any Android device with biometric authentication and any iPhone device running iOS 14 with either Face ID or Touch ID. It means that the user will have to link their accounts unless they disable the biometric authentication for the entire device. People who don’t have biometric authentication on their phones can link their accounts like they usually do.

Just like any other biometric security that you can find on other devices, the new system introduced by WhatsApp does not mean that it is collecting or accessing user fingerprint or facial data. WhatsApp uses the same biometric data APIs that are used by any other security system.

So just like using your fingerprint to access any other service does not mean that one is giving up their fingerprint data, in the same way, using WhatsApp’s biometric authentication is safe and secure. The recent privacy issues faced by the company have been quite detrimental to the reputation of WhatsApp. So, the new changes that try to protect user data must be welcomed. With the growing stress of social media companies, it is the right move for WhatsApp to ensure that users feel safe while using their services.

Will the new changes introduced by WhatsApp to protect user privacy help restore its reputation or will we see a shift of a significant number of WhatsApp users to other messaging apps like Signal or Telegram? Although it is tough to predict, the damage done by privacy concerns is irreversible. WhatsApp can only afford damage control and expect that the users who have stuck around feel safe.

Scientists Discover How Crocodiles Survived the Biggest Asteroid Strike

Crocodiles are one of the robust animals who survived the biggest asteroid strike in the Cretaceous period.

They are semi-aquatic reptiles that live in tropical regions of Asia, Africa, Australia, and America. The reptiles have an efficient body shape and versatility to survive in extreme conditions. According to recent research, these species can withstand enormous climatic changes.

The physical trait of crocodiles allows them to become successful predators. The streamlined body of the species helps them to swim. And the external structure of crocodiles is an indication of their predatory and aquatic lifestyle. Crocodiles can live in or outside the water. They can even survive in darkness. They have a tough physical design; hence they can face any climatic extremities and severe injuries.

Crocodiles generally prefer warm climatic conditions. The species are cold-blooded; hence they can not regulate their body temperatures. They take warmth from the surrounding.

Over 66 million years ago, space rocks smashed all the natural habitats, including animals and plants in the Gulf of Mexico. During that calamity, almost all living beings died, and a large species wiped out from Earth. But, crocodiles survived the tragedy by drawing the energy from the sun.

The incident speaks out loud that unlike warm-blooded animals (mammals or birds), crocodiles do not need to eat much to survive, and they do not need to change or evolve.

Over the years, the crocodile species have undergone very little change. Researchers believe that the lack of evolution and their limited diversity might help them survive the major mass extinction.

The crocodiles of today have many similarities with the crocodiles of the Jurassic period. This indicates that crocodiles have undergone slight or almost no change from some 200 million years ago. Researchers at the University of Bristol say that the species’ efficiency to withstand the severe global tragedy might be the reason for the minimum change in crocodiles or the slow rate of evolution.

Author Dr. Max Stockdale said that the crocodiles’ well-designed body might be the reason for their survival at the end of the Cretaceous period. He added that the species had a versatile lifestyle, which helped them to adapt to the extreme climatic changes.

Crocodiles can hold their breath for around one hour underwater and own an incredible ability to hold oxygen. There are only 25 species of crocodiles that are alive today. They are great swimmers and also able to move on the land with surprising speed- especially when they are angry or alarmed.

According to Dr. Stockdale and his colleagues, crocodiles have a “start-stop” phenomenon towards an evolution which majorly depends on the climate and surrounding. This pattern is known as “punctuated equilibrium” described in Nature Communications Biology. The theory proposes that some species stabilize their evolutionary rate and show very little or no changes. This state is also known as “stasis.” The phenomenon also explains why some prehistoric species are no longer alive. Many extinct species underwent “punctuated equilibrium,” including gigantic animals like dinosaurs, fast runners, diggers, plant-eaters, and water serpent-like monsters.

Dr. Stockdale, a geographical scientist, shared that his team has analyzed the species’ rate of evolution using machine learning. The evolutionary rate can be defined as the change that occurs within a species over a considerable amount of time. The researchers can find the rate of evolution by comparing different measurements from the fossils.

For the research, the scientists collect a few required data of the animal, including the species’ growth, how much food they need to survive, how fast do they grow, how big are their populations, and how they are likely to extinct.

According to the study, the researchers find out that Crocodiles can eat anything in their surroundings. They have a strong immune system. Just like bats, crocodiles can resist disease. The reptiles can survive without any large meals for a long time. Their babies mature much quickly. Crocodiles can also undergo hibernation and survive with the huge temperature drops; therefore, they survived the ice ages.

The crocodile species also flourish more in warm conditions because they need external heat to keep themselves warm. The climatic condition of the Cretaceous period was much higher than the temperature of today; hence there were more species of crocodiles in that era. Now a group of researchers has planned to study them more to find out why some prehistoric species became extinct while others survived.

Crocodiles are amazing creatures, and they have lived through two mass extinctions. The unique design of the species helps them to stand up to the ultimate living condition. Their body is able to sustain severe injuries.

Tom Cruise Resumes Mission: Impossible 7 Shooting

The shooting of the upcoming Tom Cruise’s film Mission: Impossible 7 has been resumed in the United Kingdom. The character of Ethan Hunt is returning for the seventh time after facing lots of challenges.

Christopher McQuarrie’s upcoming movie Mission: Impossible 7 is a spy film and Rogue Nation and Fallout sequel. Alongside Cruise, Rebecca Ferguson, Vanessa Kirby, Ving Rhames, Henry Czerny, Angela Bassett, and Frederick Schmidt reprise their original role, whereas Esai Morales, Hayley Atwell, Hayley Atwell will join the franchise. The installment is scheduled to release on 19 November 2021, and the sequel of the movie will be out on 4 November 2022.

On 14 January 2019, the team announced that they are working on the seventh and eighth installment of the franchise, and McQuarrie will be directing both the movies. However, the project has faced many many challenges during the making. The film was working under the title of Libra. The shooting was scheduled to start on 20 February 2020, but due to the increase in the number of coronavirus cases in Italy, the production work got halted.

After almost three weeks, the shooting resumed in July with the strict health guidelines to ensure cast and crew safety. The production of the film was again delayed as 12 people tested COVID-19 positive on the set. A week later, the shooting resumed again. Cruise had berated  a couple of crew members who he had reasons to believe had not followed safety protocols while filming the movie.

Recently, Variety confirmed that the movie’s shooting would be concluded in the United Kingdom at Longcross Film Studios, which was initially planned in Warner Bros. Studios Leavesden. Longcross used to be the United Kingdom’s Ministry of Defence site, which is now used to redevelop into the studios. Many movies like Guardians of Galaxy, Skyfall, Thor: The Dark, Artemis Fowl, The King’s Man, Death on the Nile, and The Gentlemen were shot in here.

According to the sources, Variety confirmed that the team is back from the Christmas break, shifting in the Warner Bros. Studio production. Longcross is in Surrey in Southeast England that falls within Tier 4. And the team is allowed to continue the shoot under the COVID-19 protocols.

The United Kingdom is again facing the devastating wave of the coronavirus. Since November, UK has reported a hasty increase in COVID-19 cases in London and South East England.

Hopefully, the film won’t experience any more interruptions. And the team can finish the production work peacefully after so many delays.
