Scientists may have found an affordable way to destroy forever chemicals

Posted on by

A team of scientists may have found a safe and affordable way to destroy “forever chemicals.” PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are found in many household items, including non-stick Teflon pans and dental floss. According to the US Environmental Protection Agency, at least 12,000 such substances exist today. They all share one common feature between them: a carbon-fluorine backbone that is one of the strongest known bonds in organic chemistry. It’s what gives PFAS-treated cookware its non-stick quality. However, that same characteristic can make those substances harmful to humans.

Since they’re so durable from a molecular perspective, PFAS can stay in soil and water for generations. Scientists have shown that prolonged exposure to them can lead to an increased risk of some cancers, reduced immunity and developmental effects on children. Researchers have spent years trying to find a way to destroy the carbon-fluorine bond that makes PFAS so stubborn, but a breakthrough could be in sight.

In a study published Thursday in the journal Science, a group of chemists from UCLA, Northwestern University and China found that a mixture of sodium hydroxide, a chemical used in lye, and an organic solvent called dimethyl sulfoxide was effective at breaking down a large subgroup of PFAS known as perfluoro carboxylic acids or PFCAs. When lead author Brittany Trang heated the mixture between 175 and 250 degrees Fahrenheit (about 79 to 121 degrees Celsius), it began breaking down the bonds between the PFAS molecules. After a few days, the mixture can even reduce any fluorine byproducts into harmless molecules. The sodium hydroxide is part of what makes the mixture so potent. It bonds with PFAS molecules after the dimethyl sulfoxide softens them and hastens their breakdown.

Professor William Dichtel, one of the study's co-authors, told The New York Times there’s a lot of work to be done before the solution works outside the lab. There’s also the enormity of the problem. In February, scientists estimated that humans are putting approximately 50,000 tons of PFAS chemicals into the atmosphere every year. Another recent study found that rainwater everywhere on Earth is unsafe to drink due to the ubiquity of those substances. However, scientists are understandably excited about Trang’s discovery since it may help researchers find other novel ways to destroy PFAS.

College textbook maker Pearson eyes NFTs to claim a cut of second-hand sales

Posted on by

NFT advocates often tout the technology's ability to grant the creator a cut of second-hand sales as one of its major attributes. Artists can earn from one of their digital creations years after first selling it. Others are looking at NFTs to earn a buck from the secondary market too, including the publishers of college textbooks.

Pearson, which said in 2019 it would focus on digital textbook sales, wants a piece of the action. “In the analogue world, a Pearson textbook was resold up to seven times, and we would only participate in the first sale,” CEO Andy Bird told Bloomberg this week. “The move to digital helps diminish the secondary market, and technology like blockchain and NFTs allows us to participate in every sale of that particular item as it goes through its life."

There's an obvious reason why students resell textbooks. They're expensive! Students often have to spend hundreds of dollars on required materials each semester — or even hundreds of dollars on a single textbook. Selling on a textbook when it's no longer needed just makes sense.

Turning textbooks into NFTs and banking on the blockchain to track ownership of them (from “owner A to owner B to owner C,” as Bird put it) seems unnecessary, though. Digital rights management already exists and doesn't need to go anywhere near cryptocurrency. Pearson has a $15 per month subscription service for its textbooks as well.

Bird could simply be bloviating about a zeitgeisty technology to try and keep Pearson's investors happy — even though NFT sales have plummeted this year. In any case, there's still not much he or Pearson could do to stop students from screenshotting every page of a textbook before selling it on.

How TikTok can help you get better at studying

Posted on by

When you think of study aids, TikTok is likely not what comes to mind. And, there’s probably a good reason for that. Scrolling your For You page may be entertaining, but it’s rarely productive.

But, a growing group of study influencers might be changing that. From #booktok, #studytok and #edutok, there are dozens of accounts that can help with study tips, math tutoring and even college admissions advice.

To be clear, it’s still a good idea to limit how much time you spend scrolling. And watching study-themed TikToks is not a substitute for… actually studying. But, videos from academically-minded TikTokers can offer advice on learning tough subjects and serve as inspiration for building new and productive study habits.

What to look for (and avoid)

If you’re looking for study help, well-established hashtags like #studytok or #edutok are a great place to start. Many tutors also post to TikTok, and you can find subject-specific content by adding “tutor” or “help” to the topic, like #mathtuor, #physicshelp etc.

But, as with everything on TikTok, not all study content is equal. And for every helpful account, there are also those who are sharing unhelpful shortcuts and too-good-to-be-true “study hacks.” So avoid accounts that post shady “advice” that’s actually cheating, like how to get an AI to solve your math homework or write an essay for you. And be wary of anyone who is more focused on selling products than usable advice.

Here are a few accounts that actually do a good job in the studying space.

Gohar Khan Goharsguide

Gohar Khan is most well-known for his college admissions advice, which he shares on TikTok, Instagram and YouTube. The 22-year-old recently graduated from MIT, but before that he was also accepted to Yale and Stanford. Now, he makes videos advising teens on how they can boost their chances of getting into Ivy League and other top-tier schools.

He shares videos with advice on all aspects of preparing for college, from application and essay-writing help, to how to choose a major once you get there. Even if an Ivy isn’t your ultimate goal, he also posts more general tips that will be helpful for students of all levels, In fact, some of his most popular content is geared around how to do homework more quickly, how to find the motivation to study and how to improve your test scores.

Kyle Johnson

Book lovers will appreciate Kyle Johnson’s TikToks for his concise but thoughtful book reviews and reading recommendations, but Johnson, who posts under the account panic_kyle, shares more than just reading lists. He also shares analysis of literary classics and other popular books you may often find as assigned reading in English class..

If you’re looking for a shortcut to avoid reading altogether, Johnson’s account won’t help much. He typically only gives a very brief summary of the books he covers. But if you want to think more deeply about literary themes, or get inspiration for an essay, his videos break down complex literary themes in an easy to digest way. He also shares more general advice, like how to take notes while reading fiction or how to analyze literature.

Your Bummy Math Tutor

I was awful at math when I was in school. Like, truly, awful; I had to repeat algebra three separate times. To the surprise of absolutely no one, I did not score well on the math portion of my SAT… or any other standardized test. And while I don’t know if any amount of TikTok-length videos would have helped back then, Your Bummy Math Tutor’s content makes me think it might have.

YBMT takes math questions from the SAT and practice tests and explains how to solve them, along with strategies for approaching different types of problems. It’s all fairly straightforward and yet, as a lifetime hater of math, the content is also way more engaging than any math class I can remember. Luckily for everyone, I haven’t had to do any algebra for more than a decade. But after watching enough of YBMT’s videos, I kind of feel like maybe I could solve a few problems that would have completely stumped my teenage self. At least, I might have had a few extra tools to try.

Study with soybean

You’ve probably heard of bullet journaling, the note-taking fad that’s part habit tracker, part diary and part to-do list organizer. While it can seem intimidating to start mapping out your entire life in a bullet journal, the system can be a useful study aid.

Study with soybean is a bullet journal pro whose content combines journaling inspo with study tips practical advice on how to take better notes. Her videos break down different styles of note-taking, and how to transform your notes into flashcards and other study aids. She also posts more creative content, like how to make your own greeting cards and improve your handwriting.

Google adds auto-transcription and simplified grading to its education tools

Posted on by

Many students have returned to in-person classes, but that isn't stopping Google from making online education more viable. The company has updated Classroom and Workspace for Education with a host of features that improve life for teachers and students alike. In Workspace, for instance, you can now auto-transcribe Meet calls directly into Google Docs — helpful if you want to quickly produce lesson material or help students catch up when they miss lectures. You can also host polls and Q&A sessions in Meet sessions, livestream public events (think school assemblies) to YouTube and use picture-in-picture to manage class presentations without losing sight of your pupils.

Teachers using Classroom, meanwhile, now have access to previously beta-only add-on support that extends functionality beyond what Google can offer. You can get an EdPuzzle add-on to automatically integrate and grade assignments, while a Pear Deck extension can create assignments using lessons from the Pear Deck library. The Classroom updates also make it easier to add YouTube videos to lessons, export grades and get updates through email notifications. An update later in 2022 will let teachers reply directly to students from Gmail notifications.

Google is expanding access to its Read Along app, too. It's rolling out a beta for a new web version over the next month, so students might not need to lean on their phones as they improve their literacy skills.

The announcements come alongside Chrome OS updates that include improved casting and optimizing educational apps like Figma. Although these updates might not matter much as the pandemic (hopefully) winds down, they could still be useful as schools increasingly rely on internet-based lessons and coursework.

Masterclass offers US college students three months of access for $1

Posted on by

US college students who want to keep learning over the summer break might be interested in checking out the latest promotion from Masterclass. They can get a three-month individual membership for just $1.

Masterclass hosts video-centric classes from notable, successful figures including Lewis Hamilton, Gordon Ramsay, Anna Wintour, Spike Lee and Serena Williams. The company says it now has more than 2,500 lessons on topics including gardening, writing, filmmaking, business leadership, wilderness survival and interior design.

You'll need a .edu email address and to meet a few other criteria, such as being a current student enrolled in a college or university program in the US. Masterclass says your promotional plan won't auto-renew. Once it expires, you'll have the option of continuing your membership at the regular price. The plans start at $15 per month.

It's not quite as great a deal as the one year of access for $1 Masterclass offered students in 2020. Still, it's a low-cost way to try the service and learn a thing or two.

You'll need to act swiftly if you're interested. Masterclass says there's a limited supply of promotional memberships available and the offer expires at 11:59PM PT tonight. You can sign up for the so-called Summer of Learning via a dedicated page on the Masterclass website.

A US college is shutting down for good following a ransomware attack

Posted on by

Lincoln College says it will close this week in the wake of a ransomware attack that took months to resolve. While the impact of COVID-19 severely impacted activities such as recruitment and fundraising, the cyberattack seems to have been the tipping point for the Illinois institution.

The college has informed the Illinois Department of Higher Education and Higher Learning Commission that it will permanently close as of May 13th. As NBC News notes, it's the first US college or university to shut down in part because of a ransomware attack.

Lincoln says it had "record-breaking student enrollment" in fall 2019. However, the pandemic caused a sizable fall in enrollment with some students opting to defer college or take a leave of absence. The college — one of only a few rural schools to qualify as a predominantly Black institution under the Department of Education — said those affected its financial standing.

Last December, Lincoln was hit by a cyberattack, which "thwarted admissions activities and hindered access to all institutional data, creating an unclear picture of fall 2022 enrollment. All systems required for recruitment, retention and fundraising efforts were inoperable," the college said in a statement posted on its homepage. "Fortunately, no personal identifying information was exposed. Once fully restored in March 2022, the projections displayed significant enrollment shortfalls, requiring a transformational donation or partnership to sustain Lincoln College beyond the current semester."

Barring a last-minute respite, the one-two punch of the pandemic and a cyberattack have brought an end to a 157-year-old institution. Lincoln says it will help students who aren't graduating this semester transfer to another college.

Over the last few years, ransomware hackers have attacked other educational facilities, as well as hospitals, game studios, Sinclair Broadcast Group and many other companies and institutions.

Google Nest cameras now work with Amazon Alexa devices

Posted on by

The smart home ecosystem is getting a little more integrated: Google just updated its Amazon Alexa Skill to work on its latest Nest cameras. So if you already own a variety of Nest and Alexa devices, they'll work together more seamlessly moving forward. Now, you can stream live feeds from your Nest cameras, doorbells and other devices to anything from your Amazon Fire TV to any Echo device. Amazon made a similar gesture to open up its own smart home ecosystem last month, when it announced that its doorbells and security cameras would work with Google Nest, Ring, Abode and other third-party devices. Amazon’s Ring doorbell already works with Google Home and Apple Homekit.

A few other integrations between Nest and Alexa have been available for a while. For example, if you own a Google Nest thermostat, you can tell Alexa to change the temperature of your home. Older Nest cameras and doorbells have also had limited Alexa abilities, but the new skill allows for even more cross-platform integration. According to a recent post on Google Nest’s blog, the updated skill means Alexa will now support streaming from the Nest Cam with Floodlight, as well as the battery-powered models of Nest Cam and Nest Doorbell to the Echo Show, Fire TV or Fire Tablets.

If you own a Nest Doorbell, you can also talk to people through your door with any of your Alexa devices (such as the Echo, Echo Show, Fire TV and Fire Tablet). Eventually, Alexa will be able to announce when a Nest Cam or Nest Doorbell detects a person at your front door as well.
