Why Google Has Sat on the Web3 Sidelines (bloomberg.com) 6

An anonymous reader shares a report: Google doesn't accept cryptocurrencies for ad buying, its payments service or its app store. Until recently, Google had banned several categories of crypto ads. Google hasn't touched NFTs. In a recent interview with Bloomberg Television, Chief Executive Officer Sundar Pichai copped that he "dabbled" in crypto, but didn't own any. Some staffers at Google have also dabbled with the technology, according to multiple current and former employees at the company. Still, Google hasn't laid out a plan for inserting itself into web3. A Google spokesperson said its mobile payments service is "working with several companies" such as Coinbase, Bitpay and Gemini "to support crypto cards, which transact in fiat currencies."

There are a few reasons Google might not want to dive into the new arena -- one is defensive. Web3 evangelists see the technology as "decentralized," controlled by its many participants. They draw stark contrasts to the business models of Google, Facebook and Amazon. These boosters see the blockchain as inherently trustworthy, unlike the current web titans. "Can't do evil > don't be evil," tweeted Chris Dixon, an Andreessen Horowitz partner, in a clear dig at Google. And many Silicon Valley visions for web3 activity, search engines and media decidedly don't involve advertising, Google's main business. But the company isn't completely averse to cryptocurrency. Google has been willing to take crypto money for its cloud business. In September, the division signed a deal with Dapper Labs, a Canadian blockchain company. It also has agreements with Hadera, Block.one and others. Given web3's escalating computing demands, Google will certainly look to ink more of these. (Google will have to weigh crypto's energy needs versus the company's zero-emissions targets.) In some ways, the wait-and-see strategy is typical of Pichai, who has a more deliberate management style than his predecessors. And that doesn't mean the company isn't quietly exploring the technology.

India Approves $10 Billion Plan To Lure Semiconductor and Display Makers (reuters.com) 3

India has approved a $10 billion incentive plan to attract semiconductor fabricators and display manufacturers, its technology minister said on Wednesday, as part of efforts to establish itself as a global electronics production hub. From a report: Israel's Tower Semiconductor, Apple's contract manufacturer Foxconn and a Singapore-based consortium have all shown interest in setting up semiconductor fabrication units in India, a government source told Reuters. New Delhi also approved a design linked incentive (DLI) plan to encourage 100 local companies in semiconductor design for integrated circuits and chipsets, technology minister Ashwini Vaishnaw told a news briefing.

Presentations Point To Greater Huawei Role In China Surveillance Than Acknowledged (thehill.com) 21

An anonymous reader quotes a report from The Hill: PowerPoint presentations from Chinese telecommunications giant Huawei Technologies indicate that the company has a larger role in China's surveillance efforts than was previously known, according to The Washington Post. The Post reviewed over 100 Huawei PowerPoint presentations, many of them labeled "confidential," in which the company detailed how the government could use its technologies to identify voices, track people for political purposes and monitor the movements of inmates within prisons, among other surveillance tactics.

While the Post could not confirm who the presentations were shown to, the newspaper said that PowerPoints detailing surveillance tactics specific to government agencies -- such as slides appearing to refer to China's controversial prison reeducation and labor programs -- may have been intended for government audiences. While China's Communist Party depends on tools such as facial recognition to find dissenters, it has warned tech companies like Huawei against misusing the technology in the private sector, the Post said.
"Huawei has no knowledge of the projects mentioned in the Washington Post report," the company said in a statement to the Washington Post. "Like all other major service providers, Huawei provides cloud platform services that comply with common industry standards."

Rocket Scientists and Brain Surgeons Aren't Necessarily More Clever, Study Finds (bbc.com) 91

Thelasko shares a report from the BBC: Considering a career in brain surgery or rocket science? It might well be within reach. Members of both professions aren't necessarily more clever than the general public, according to a study. Researchers asked 329 aerospace engineers and 72 neurosurgeons to complete a series of tasks to test their cognition. The results, published in the British Medical Journal, show few differences with members of the British public.

Professionals from both groups were assessed online in six cognitive domains, using a 'Great British Intelligence Test' originally devised at Imperial College, London. The test looked at areas like working memory, attention and emotion processing, and respondents were asked about their age, sex and industry experience. The results were then compared between both groups, and data previously gathered from 18,000 members of the British public. It found that neurosurgeons scored significantly higher than rocket scientists in semantic problem solving, like defining rare words. Aerospace engineers, meanwhile, performed better than their rivals when it came to attention, and to mental manipulation tasks like rotating images of objects in one's head. When compared with public scores, however, rocket scientists didn't show significant differences in any domains.

Neuroscientists, on the other hand, scored differently in only two areas: their problem solving speed was quicker, but their memory recall was slower. Researchers suggested this may be due to the "fast-paced nature of neurosurgery... or it could be, albeit less likely, a product of training for rapid decision-making in time-critical situations." "It is possible that both neurosurgeons and aerospace engineers are unnecessarily placed on a pedestal," the study reflected. "Other specialties might deserve to be on that pedestal, and future work should aim to determine the most deserving profession."

NASA's Parker Solar Probe Becomes First Spacecraft To 'Touch' the Sun (cnn.com) 39

Sixty years after NASA set the goal, and three years after its Parker Solar Probe launched, the spacecraft has become the first to "touch the sun." CNN World reports: The Parker Solar Probe has successfully flown through the sun's corona, or upper atmosphere, to sample particles and our star's magnetic fields. The announcement was made at the 2021 American Geophysical Union Fall Meeting in New Orleans on Tuesday, and research from the solar milestone has been published in the Physical Review Letters.

The Parker Solar Probe launched in 2018 and set out to circle closer and closer to the sun. Scientists, including the spacecraft's namesake astrophysicist Eugene Parker, want to answer fundamental questions about the solar wind that streams out from the sun, flinging energetic particles across the solar system. The sun's corona is much hotter than the actual surface of the star, and the spacecraft could provide insight about why. The corona is one million degrees Kelvin (1,800,000 degrees Fahrenheit) at its hottest point, while the surface is around 6,000 Kelvin (10,340 degrees Fahrenheit).

The spacecraft has already revealed surprising finds about the sun, including the 2019 discovery of magnetic zig-zag structures in the solar wind called switchbacks. Now, thanks to Parker's latest close approach to the sun, the spacecraft helped scientists determine that these switchbacks originate from the solar surface. Before Parker Solar Probe's mission is done, it will have made 21 close approaches to the sun over the course of seven years. The probe will orbit within 3.9 million miles of the sun's surface in 2024, closer to the star than Mercury -- the closest planet to the sun.

Scientists Urge Creating Strategic Forest Reserves To Mitigate Climate Change, Protect Biodiversity (phys.org) 71

An anonymous reader quotes a report from Phys.Org: The United States should immediately move to create a collection of strategic forest reserves in the Western U.S. to fight climate change and safeguard biodiversity, according to a scientific collaboration led by an Oregon State University ecologist. Bev Law, her College of Forestry colleague William Ripple and other scientists from around the West argue that climate change and biodiversity are inextricably linked and that strategic forest reserves would tackle both "emergencies" while also promoting the protection of water resources.

Describing the U.S.'s natural wooded systems as "America's Amazon" and forest protection as "the lowest-cost climate mitigation option," the researchers emphasize older forests' ability to accumulate massive amounts of carbon in trees, vegetation and soils, to provide homes for wildlife and to serve as sources of water for drinking and other uses. The scientists note that multiple nations have pledged to meet goals commonly known as 30x30 and 50x50; the former calls for protecting 30% of land and water areas globally by 2030, the latter 50% by 2050. Hitting the 50x50 target is widely viewed as necessary for ensuring the Earth's biodiversity, the researchers say. [...] The scientists note that multiple nations have pledged to meet goals commonly known as 30x30 and 50x50; the former calls for protecting 30% of land and water areas globally by 2030, the latter 50% by 2050. Hitting the 50x50 target is widely viewed as necessary for ensuring the Earth's biodiversity, the researchers say.

The framework produces preservation priority rankings by using spatial metrics of biodiversity, carbon stocks and accumulation under climate change and future vulnerability to drought or wildfire. In the West the highest priority forestlands are mainly under federal ownership, with substantial areas controlled by private entities and state and tribal governments. Many federal forest lands would reach GAP 2 protection simply by phasing out grazing, mining and logging and strengthening protection via administrative rule. Inventoried roadless areas make up almost 42 million acres of national forest in the West and are readily available for permanent protection.
The researchers lay out their framework for developing the reserves in a paper published in the journal Communications Earth & Environment.

"GAP 1, as defined by the U.S. Geological Survey, refers to permanent protection such as wilderness areas and national parks, where natural disturbances such as fire can proceed without interference or are mimicked via management activities," notes Phys.Org. "On GAP 2 lands, uses or practices that degrade the quality of existing natural communities, such as road building, may be allowed, and suppression of natural disturbances is allowed as well."

Google Is Building a New AR Device and OS (arstechnica.com) 13

According to job listings on LinkedIn, Google appears to be working on an augmented reality device and operating system to pair with it. Ars Technica reports: On LinkedIn, operating system engineering director Mark Lucovsky announced that he has joined Google. He previously headed up mixed reality operating system work for Meta, and before that he was one of the key architects of Windows NT at Microsoft. "My role is to lead the Operating System team for Augmented Reality at Google," he wrote. He also posted a link to some job listings at Google that give the impression Google is getting just as serious about AR as Apple or Meta.

As 9to5Google discovered, one of the listings ("Senior Software Developer, Embedded, Augmented Reality OS") described Google's objective in clear terms: "Our team is building the software components that control and manage the hardware on our Augmented Reality (AR) products. These are the software components that run on the AR devices and are the closest to the hardware. As Google adds products to the AR portfolio, the OS Foundations team is the very first software team to work with new hardware." Other job listings say new hires will be working on an "innovative AR device." And one specifies that Google is "focused on making immersive computing accessible to billions of people through mobile devices." The roles are largely in the United States, but some are located in Waterloo, Ontario -- the HQ of Canadian smart glasses maker North, which Google acquired in 2020.

Bitcoin Could Become 'Worthless,' Bank of England Warns (theguardian.com) 185

The Bank of England has said that bitcoin could be "worthless" and people investing in the digital currency should be prepared to lose everything. The Guardian reports: In a warning over the potential risks for investors, the central bank questioned whether there was any inherent worth in the most prominent digital currency, which has soared in value this year to close to $50,000 a piece. The deputy governor, Sir Jon Cunliffe, said the Bank had to be ready for risks linked to the rise of the crypto asset following rapid growth in its popularity. "Their price can vary quite considerably and [bitcoins] could theoretically or practically drop to zero," he told the BBC.

The Bank's financial policy committee, set up in the wake of the 2008 financial crisis to monitor risks, said on Monday there was little direct threat to the stability of the UK financial system from crypto assets. However, it warned that, at the current rapid pace of growth, such assets could become more interconnected with traditional financial services and were likely to pose a number of risks. Publishing its regular health check on the financial system, the Bank said major institutions should take a cautious approach to adopting crypto assets and that it would pay close attention to developments in the market. "Enhanced regulatory and law enforcement frameworks, both domestically and at a global level, are needed to influence developments in these fast-growing markets in order to manage risks, encourage sustainable innovation and maintain broader trust and integrity in the financial system," it said. In a separate blogpost published on its website on Tuesday, a member of the Bank's staff said bitcoin failed to fulfill many of the features required of a currency and that it risked being inherently volatile.

Thomas Belsham, who works in the Bank's stakeholder and media engagement division, wrote: "The problem is that, unlike traditional forms of money, Bitcoin isn't used to price things other than itself. As Bitcoiners themselves are fond of saying, 'one Bitcoin = one Bitcoin'. But a tautology does not a currency make." He said scarcity of the crypto asset -- which is limited to 21m bitcoin -- is among the key reasons for its attraction for investors, but this feature embedded into its design "may even, ultimately, render Bitcoin worthless." About 19m bitcoin is currently in circulation, with new coins added when "miners" validate changes to the blockchain ledger underpinning the cryptocurrency. While the ultimate number of bitcoin in circulation is not expected to be reached until February 2140, it would become harder to sustain this system over time, Belsham said. "Simple game theory tells us that a process of backward induction should, really, at some point, induce the smart money to get out. And were that to happen, investors really should be prepared to lose everything. Eventually."

Dell's Luna Laptop Concept Is All About Repairability (theverge.com) 49

On Tuesday, Dell announced a new design concept for a laptop that's long lived, easy to take apart and fix, and takes a smaller toll on the climate. The Verge reports: Called "Concept Luna," the proof-of-concept laptop dreamed up by Dell's design team has a number of unusual features that are intended to make repair and maintenance easy. No screwdrivers or glue solvents are needed to pry loose a broken keyboard or peel off a cracked screen; both components simply pop free after a pair of keystones holding them in place are removed. The entire system contains far fewer screws than a typical Dell laptop, reducing the time needed to replace components. And you'll never have to worry about replacing a broken fan, because there isn't one: a shrunken-down motherboard placed in the top cover allows the laptop to passively cool itself.

Dell design strategist Drew Tosh described Luna as a "front end concept" intended to "solve some of the larger problems we're trying to get ahead of in the future," namely e-waste and climate change. A laptop that is easy to repair and upgrade is less likely to be replaced with a new one that takes yet more energy and resources to produce. When that computer eventually does stop working, parts can be harvested to live on in other machines rather than winding up as toxic trash in landfills. [...] "We're really focused on reuse and recycle," Tosh told The Verge. "And really, it would be more like reuse, reuse, reuse, and recycle only when we really have to." So far, only several prototype versions of this laptop exist. But the design Dell is showing off is as sleek and portable as any laptop in the company's current lineup.

Other ideas in Concept Luna are more focused on the climate impact of electronics. The aluminum in the chassis is smelted using hydropower energy, replacing what is often one of the dirtiest manufacturing steps with a low-carbon alternative. The motherboard is a quarter the size of the board in the Latitude 7300 AE, and according to Dell, it could have a 50 percent smaller carbon footprint. A life cycle analysis of the Latitude 7300 AE found that manufacturing accounted for 65 percent of the device's climate impact and printed wire boards were the most energy-intensive components to make. Considering Dell's leading position in the global laptop market, this level of carbon cutting on an individual parts basis could translate to significant reductions across the industry. Another key factor determining how long lived any laptop will be is the availability of spare parts for repair -- most importantly, screens and batteries [...]. [I]ndividuals can already order "tens of thousands" of spare parts from Dell, including replacement screens and batteries, however, these components are often unavailable for purchase online. [I]ncreasing the number of spare parts customers can buy online is "something we are working on right now."

USPS Built and Secretly Tested a Blockchain-Based Mobile Voting System Before 2020 (washingtonpost.com) 41

An anonymous reader quotes a report from The Washington Post: The U.S. Postal Service pursued a project to build and secretly test a blockchain-based mobile phone voting system before the 2020 election (Warning: may be paywalled; alternative source), experimenting with a technology that the government's own cybersecurity agency says can't be trusted to securely handle ballots. The system was never deployed in a live election and was abandoned in 2019, Postal Service spokesman David Partenheimer said. That was after cybersecurity researchers at the University of Colorado at Colorado Springs conducted a test of the system during a mock election and found numerous ways that it was vulnerable to hacking.

The project appears to have been conducted without the involvement of federal agencies more closely focused on elections, which were then scrambling to make voting more secure in the wake of Russian interference in the 2016 contest. Those efforts focused primarily on using paper ballot so the voter could verify their vote was recorded accurately and there would be a paper trail for auditors -- something missing from any mobile phone or Internet-based system. The project appears to have been conducted without the involvement of federal agencies more closely focused on elections, which were then scrambling to make voting more secure in the wake of Russian interference in the 2016 contest. Those efforts focused primarily on using paper ballot so the voter could verify their vote was recorded accurately and there would be a paper trail for auditors -- something missing from any mobile phone or Internet-based system.

The Postal Service system allowed people to cast votes on an Internet-connected mobile app similar to how they might add items to an online shopping cart or fill out an online survey. The votes were designed to be anonymous and to be recorded in multiple digital locations simultaneously. The idea is that each of those digital records would act as a check to verify the accuracy of the other records. This is essentially the same method that cryptocurrencies such as bitcoin use to ensure transactions are accurately recorded. But the system didn't protect against the numerous ways hackers might fake or corrupt votes, the University of Colorado researchers said. Those include impersonating voters, attacking the blockchain system itself so votes can't be trusted, flooding the system with information so it becomes too overwhelmed to function, and using techniques that undermine voters' privacy and the secrecy of the ballot. The researchers were able to successfully perform all those hacks during a mock election held on campus.
"The Postal Service was awarded a public patent for the concept in August 2020, but had not previously revealed that it built a prototype system or tested it," the report notes.

Masayuki Uemura, Designer of the Nintendo Entertainment System, Dies At 78 (nytimes.com) 15

"The New York Times has an obituary for Masayuki Uemura, designer of the first Nintendo Entertainment System console," writes Slashdot reader nickovs. Here's an excerpt from the report: Video game consoles had a moment of popularity in the early 1980s, but the market collapsed because of shoddy quality control and uninspiring software that failed to provide the thrills of arcade hits like Pac-Man and Space Invaders. Truckloads of unsold game cartridges ended up in landfills, and retailers decided that home gaming systems had no future. But in 1985, the release of the Nintendo Entertainment System in the United States changed the industry forever. The unassuming gray box with its distinctive controllers became a must-have for an entire generation of children and prompted Nintendo's virtual monopoly over the industry for the better part of a decade as competitors pulled out of the market in response to the company's dominance. "The NES was not the first video game console," adds nickovs. "The quality of the games that became available for the NES, including titles like Super Mario Brothers, made it much more appealing than pervious boxes and that lead to its commercial success. These games would not have been possible without the hardware that Uemura designed."

YouTube TV Warns It May Lose All Disney-Owned Channels Amid Contract Dispute (arstechnica.com) 44

YouTube TV yesterday warned that it could lose all Disney-owned channels after Friday because of a contract dispute and said it will temporarily reduce its price by $15 a month if that happens. Ars Technica reports: "We're now in negotiations with Disney to continue distributing their content on YouTube TV so you can continue watching everything from your favorite teams on ESPN to The Bachelor to Good Morning America. Our deal expires on Friday, December 17, and we haven't been able to reach an equitable agreement yet, so we wanted to give you an early heads up so that you can understand your choices," the Google-owned YouTube wrote in a blog post.

"[I]f we are unable to reach a deal by Friday, the Disney-owned channels will no longer be available on YouTube TV and we will decrease our monthly price by $15, from $64.99 to $49.99 (while this content remains off our platform)," the blog post said. YouTube noted that users can pause or cancel their YouTube TV subscriptions at any time and subscribe to the Disney Bundle for $13.99 a month.

YouTube's statement that it wants "equitable" terms indicates that it is seeking a most-favored-nation (MFN) clause from Disney. "Our ask to Disney, as with all our partners, is to treat YouTube TV like any other TV provider -- by offering us the same rates that services of a similar size pay, across Disney's channels for as long as we carry them. If Disney offers us equitable terms, we'll renew our agreement with them," YouTube wrote. When contacted by Ars, Disney said that the contract is scheduled to expire on Friday at 11:59 pm ET and covers "the ABC Owned Television Stations, the ESPN networks, the Disney channels, Freeform, the FX networks, and the National Geographic channels."
In an email to Ars, Disney expressed confidence that the companies can get a deal done: "Disney Media and Entertainment Distribution has a highly successful track record of negotiating such agreements with providers of all types and sizes across the country and is committed to working with Google to reach a fair, market-based agreement. We are optimistic that we can reach a deal and continue to provide their YouTube TV customers with our live sporting events and news coverage, plus kids, family, and general entertainment programming."

What Is Web3 and Why Should You Care? (gizmodo.com) 102

Gizmodo's David Nield explains what Web3 is, what it will mean for the future, and how exactly the third-generation internet differs from the first two. An anonymous reader shares an excerpt from his report: Let's cut to the chase: For Web3 evangelists, it's a revolution; for skeptics, it's an overhyped house of cards that doesn't stand up to much scrutiny. [...] As you might remember if you're of a certain age, Web 1.0 was the era of static webpages. Sites displayed news and information, and maybe you had your own little corner of the World Wide Web to show off your personal interests and hobbies. Images were discouraged -- they took up too much bandwidth -- and video was out of the question. With the dawn of the 21st century, Web 1.0 gave way to Web 2.0 -- a more dynamic, editable, user-driven internet. Static was out and webpages became more interactive and app-like (see Gmail, for example). Many of us signed up for social media accounts and blogs that we used to put our own content on the web in vast amounts. Images and video no longer reduced sites to a crawl, and we started sharing them in huge numbers. And now the dawn of Web3 is upon us. People define it in a few different ways, but at its core is the idea of decentralization, which we've seen with cryptocurrencies (key drivers of Web3). Rather than Google, Apple, Microsoft, Amazon, and Facebook (sorry, Meta) hoarding everything, the internet will supposedly become more democratized.

Key to this decentralization is blockchain technology, which creates publicly visible and verifiable ledgers of record that can be accessed by anyone, anywhere. The blockchain already underpins Bitcoin and other cryptocurrencies, as well as a number of fledging technologies, and it's tightly interwoven into the future vision of everything that Web3 promises. The idea is that everything you do, from shopping to social media, is handled through the sane secure processes, with both more privacy and more transparency baked in. In some ways, Web3 is a mix of the two eras that came before it: The advanced, dynamic, app-like tech of the modern web, combined with the decentralized, user-driven philosophy that was around at the start of the internet, before billion- and trillion-dollar corporations owned everything. Web3 shifts the power dynamic from the giant tech entities back to the users -- or at least that's the theory.

In its current form, Web3 rewards users with tokens, which will eventually be used in a variety of ways, including currency or as votes to influence the future of technology. In this brave new world, the value generated by the web will be shared out between many more users and more companies and more services, with much-improved interoperability. NFTs are closely linked to the Web3 vision. [...] For our purposes here, the link between cryptocurrencies, NFTs, and Web3 is the foundation: the blockchain. Throw in some artificial intelligence and some machine learning to do everything from filter out unnecessary data to spot security threats, and you've got just about every emerging digital technology covered with Web3. Right now Ethereum is the blockchain attracting the most Web3 interest (it supports both a cryptocurrency and an NFT system, and you can do everything from make a payment through it to build an app on it).

Intel's Mystery Linux Muckabout is a Dangerous Ploy at a Dangerous Time (theregister.com) 62

Open source is no place for secrets. From a report: This is a critical time for the Good Chip Intel. After the vessel driftied through the Straits of Lateness towards the Rocks of Irrelevance, Captain Pat parachuted into the bridge to grab the helm and bark "Full steam ahead!" Its first berth at Alder Lake is generally seen as a return to competitive form, but that design started well before Gelsinger's return and there's still zero room for navigational errors in the expeditions ahead. At least one of the course corrections looks a bit rum. Intel has long realised the importance of supporting open source to keep its chips dancing with Linux. Unlike the halcyon days of Wintel dominance, though, this means being somewhat more open about the down-and-dirty details of exactly how its chips do their thing. You can't sign an NDA with the Linux kernel.

Chipmakers are notoriously paranoid: Silicon Valley was born in intrigue and suspicion. Despite Intel's iconic CEO Andy Grove making paranoia a corporate mantra, Intel became relatively relaxed. Qualcomm and Apple would throw you into their piranha pools merely for asking questions if they could, while Intel has learned to give as well as take. But it may be going back to bad habits. One of the new things not open to discussion is something called Software Defined Silicon (SDSi), about which Intel has nothing to say. Which is odd because it has just submitted supporting code for it to the Linux kernel. The code itself doesn't say anything about SDSi, instead adding a mechanism to control whatever it is via some authorised secure token. It basically unlocks hardware features when the right licence is applied. That's not new. Higher performance or extra features in electronic test equipment often comes present but disabled on the base models, and the punter can pay to play later. But what might it mean in SDSi and the Intel architecture?

It is expensive for Intel and OEMs alike to have multiple physical variants of anything; much better if you make one thing that does everything and charge for unlocking it. It's a variant of a trick discovered by hackish school kids in the late 1970s, where cheaper Casio scientific calculators used exactly the same hardware as the more expensive model. Casio just didn't print all the functions on the keyboards of the pleb kit. Future Intel chips will doubtless have cores and cache disabled until magic numbers appear, and with the SoC future beckoning that can extend to all manner of IO, acceleration, and co-processing features. It might even be there already. From engineering, marketing, and revenue perspectives, this is great. Intel could make an M1-like SoC that can be configured on the fly for different platforms, getting the design, performance, and fab efficiencies that Apple enjoys while making sense for multiple OEMs. There could be further revenue from software upgrades, or even subscription models.

Bugs Across Globe Are Evolving To Eat Plastic, Study Finds (theguardian.com) 78

Microbes in oceans and soils across the globe are evolving to eat plastic, according to a study. The research scanned more than 200m genes found in DNA samples taken from the environment and found 30,000 different enzymes that could degrade 10 different types of plastic. From a report: The study is the first large-scale global assessment of the plastic-degrading potential of bacteria and found that one in four of the organisms analysed carried a suitable enzyme. The researchers found that the number and type of enzymes they discovered matched the amount and type of plastic pollution in different locations. The results "provide evidence of a measurable effect of plastic pollution on the global microbial ecology," the scientists said.

Millions of tonnes of plastic are dumped in the environment every year, and the pollution now pervades the planet, from the summit of Mount Everest to the deepest oceans. Reducing the amount of plastic used is vital, as is the proper collection and treatment of waste. But many plastics are currently hard to degrade and recycle. Using enzymes to rapidly break down plastics into their building blocks would enable new products to be made from old ones, cutting the need for virgin plastic production. The new research provides many new enzymes to be investigated and adapted for industrial use.
