Scientists have discovered the origins of the building blocks of life

Rutgers researchers have discovered the origins of the protein structures responsible for metabolism: simple molecules that powered early life on Earth and serve as chemical signals that NASA could use to search for life on other planets.

Their study, which predicts what the earliest proteins looked like 3.5 billion to 2.5 billion years ago, is published in the journal Proceedings of the National Academy of Sciences.

The scientists retraced, like a many thousand piece puzzle, the evolution of enzymes (proteins) from the present to the deep past. The solution to the puzzle required two missing pieces, and life on Earth could not exist without them. By constructing a network connected by their roles in metabolism, this team discovered the missing pieces.

“We know very little about how life started on our planet. This work allowed us to glimpse deep in time and propose the earliest metabolic proteins,” said co-author Vikas Nanda, a professor of Biochemistry and Molecular Biology at Rutgers Robert Wood Johnson Medical School and a resident faculty member at the Center for Advanced Biotechnology and Medicine. “Our predictions will be tested in the laboratory to better understand the origins of life on Earth and to inform how life may originate elsewhere. We are building models of proteins in the lab and testing whether they can trigger reactions critical for early metabolism.”

“We think we have found the building blocks of life—the Lego set that led, ultimately, to the evolution of cells, animals and plants.”

The Rutgers team focused on two “folds” that are likely the first structures in early metabolism. They are a ferredoxin fold that binds iron-sulfur compounds, and a “Rossmann” fold, which binds nucleotides (the building blocks of DNA and RNA). These are two pieces of the puzzle that must fit in the evolution of life.

There is evidence the two folds may have shared a common ancestor and, if true, the ancestor may have been the first metabolic enzyme of life.

Universal to release movies online while they are in theaters, starting with ‘Trolls World Tour’

With the spreading coronavirus pandemic forcing movie theaters to close, Comcast is breaking with tradition and making a number of new movies available to watch at home.

Universal’s “Trolls World Tour” will be the first movie it will simultaneously debut online and in theaters on April 10. Other films that are currently in theaters, like “The Invisible Man,” “The Hunt” and “Emma” will be available for a 48-hour rental as soon as Friday with the suggested price of $19.99.

Typically, movie studios wait 90 days for a film to run in theaters before putting it out to home viewing, but the company will be releasing new films online while they are still in cinemas.

Notably, Universal has decided to implement this new policy for its low-to-mid-tier budgeted films. The budget for “Trolls World Tour” is half that figure, “Invisible Man” was around $7 million and “The Hunt” was around $14 million.

Meanwhile, the release of the upcoming “F9” was pushed from May 2020 to April 2021. The budget for “F9″ is likely on par of that of its predecessor “The Fate of the Furious,” which cost $250 million to make, excluding marketing.

“NBCUniversal will continue to evaluate the environment as conditions evolve and will determine the best distribution strategy in each market when the current unique situation changes,” Jeff Shell, CEO of NBCUniversal, said in a statement Monday.

“Trolls World Tour” is the sequel to Dreamworks and Universal’s animated hit from 2016 “Trolls.” With schools around the country closing and more people seeking to self-quarantine or being ordered to stay at home, “Trolls World Tour” wasn’t likely to draw big crowds. Many theaters that remain open in the U.S. have capped the number of people who can attend.

Making this kid’s film available online allows parents to keep their kids safe from the transmission of COVID-19, but also entertained.

Brave Browser Delivers on Promise, Files GDPR Complaint Against Google

Earlier today, March 16, Brave filed a formal complaint against Google with the lead General Data Protection Regulation (GDPR) enforcer in Europe.

In a February Cointelegraph interview, Dr. Johnny Ryan, Brave’s chief policy and industry relations officer, explained that Google is abusing its power by sharing user data collected by dozens of its distinct services, creating a “free for all” data warehouse. According to Ryan, this was a clear violation of the GDPR.

Aggravated with the situation and the lack of enforcement against the giant, Ryan promised to take Google to court if things don’t change for the better.

Complaint against Google

Now, the complaint is with the Irish Data Protection Commission. It accuses Google of violating Article 5(1)b of the GDPR. Dublin is Google’s European headquarters and, as Dr. Ryan explained to Cointelegraph, the Commission “is responsible for regulating Google’s data protection across the European Economic Area”.

Article 5(1)b of the GDPR requires that data be “collected for specified, explicit and legitimate purposes and not further processed in a manner that is incompatible with those purposes”. According to Dr. Ryan:

“Enforcement of Brave’s GDPR ‘purpose limitation’ complaint against Google would be tantamount to a functional separation, giving everyone the power to decide what parts of Google they chose to reward with their data.”

Google is a “black box”

Dr. Ryan has spent six months trying to elicit a response from Google to a basic question: “What do you do with my data?” to no avail.

Alongside the complaint, Brave released a study called “Inside the Black Box”, that:

“Examines a diverse set of documents written for Google’s business clients, technology partners, developers, lawmakers, and users. It reveals that Google collects personal data from integrations with websites, apps, and operating systems, for hundreds ill-defined processing purposes.”

Brave does not need regulators to compete with Google

Cointelegraph asked Dr. Ryan how Google’s treatment of user data frustrates Brave as a competitor, to which  Dr. Ryan replied:

“The question is not relevant. Brave does not —  as far as I am aware — have direct frustrations with Google. Brave is growing nicely by being a particularly fast, excellent, and private browser. (It doesn’t need regulators to help it grow.)”

A recent privacy study indicated that Brave protects user privacy much better than Google Chrome or any other major browser.

In addition to filing a formal complaint with the Irish Data Protection Commission, Brave has reportedly written to the European Commission, German Bundeskartellamt, UK Competition & Markets Authority, and French Autorité de la concurrence.

If none of these regulatory bodies take action against Google, Brave has suggested that it may take the tech giant to court itself.
