LinkedIn will now require some users to verify their identity before they change job titles in an attempt to cut down on scams on the platform. The new identity verification rules will specifically apply to executives and recruiters who interact with job seekers or represent a company in one form or another.

As part of these changes, LinkedIn says users who add or update their title to anything recruiter-related (recruiter, talent acquisition, etc.) will have to verify their workplace on their profiles. The same identity verification rules will apply to executives, as well, which LinkedIn says covers titles like "Executive Director, Managing Director, and Vice President." Verifying your workplace requires you to provide an official email address that uses your company’s domain name. The new requirement only applies to people changing roles, existing recruiters and executives won’t have to verify.

LinkedIn has offered similar verification tools to select companies upon request, but now the platform says it’ll open up the option to every company with a LinkedIn page via a new "Premium Company Page subscription." A verified company should be easier to trust when paired with verified employees.

While LinkedIn is best known as a home for thought leadership and a necessary evil in job hunts, it’s also the site of a large amount of fraud. Scammers impersonate company employees to collect data from fake job postings or conduct elaborate investment schemes, as CNBC reported in 2022. LinkedIn has automated systems for weeding out fake accounts, and rolled out an earlier wave of anti-scam features focused on job postings in 2023, but this new system should offer even more security.

Easier plastic recycling is on the horizon

https://www.popsci.com/environment/plastic-recycling-catalyst/

The age of pre-sorting mixed plastic waste may soon be over. The secret weapon? A cheap catalyst made from nickel that targets one of our most problematic polymers. The findings are detailed in a study published September 2 in the journal Nature Chemistry.

Even after decades of worldwide efforts, recycling plastic remains much easier said than done. The frustrating reality is largely thanks to a group of polymers called polyolefins. Humans manufacture roughly 220 million tons of polyolefin-based products every year, most of which are single-use items like condiment bottles, milk jugs, plastic wrap, trash bags, and juice cartons.

“Basically, almost everything in your refrigerator is polyolefin based,” Northwestern University chemist and study co-author Yosi Kratish said in a statement

Plastics are typically broken down using catalysts–compounds capable of exploiting weak chemical bonds to kickstart decomposition in the materials that otherwise take hundreds or thousands of years to deteriorate. 

We annually recycle less than 10 percent of polyolefin products, resulting in mountains of waste destined for either landfills or industrial furnaces. That’s because while other plastics are typically broken down with catalysts, polyolefins are a different story. These resilient polymers resist eroding due to tiny molecules linked by notoriously tough carbon-carbon bonds.

“Polyolefins don’t have any weak links. Every bond is incredibly strong and chemically unreactive,” said Kratish.

Our current solutions aren’t “solutions” so much as stopgaps. Polyolefin products can be shredded, melted, and downcycled into low-quality plastic pellets, but even then there are caveats. Human-assisted separating is still necessary, and even the smallest amounts of food residue or non-plastic material can compromise an entire batch. Meanwhile, burning polyolefins requires temperatures as high as 1,292 degrees Fahrenheit.

“Everything can be burned, of course,” said Kratish. “If you apply enough energy, you can convert anything to carbon dioxide and water. But we wanted to find an elegant way to add the minimum amount of energy to derive the maximum value product.”

A potential solution may reside in hydrogenolysis, a process in which a combination of hydrogen gas and a catalyst deconstruct polyolefin plastic into actually useful hydrocarbons. Existing hydrogenolysis options also involve high temperatures and expensive, noble metal-derived catalysts, but Kratish’s team found a workaround.

Unlike rare earth metals like palladium and platinum, engineers discovered that a synthesized alternative called cationic nickel is cheap, abundant, and easy to amass. Other nickel-based catalysts include multiple reaction sites. Cationic nickel’s single-site variant allows it to function more like a precise laser or sharp knife. Instead of breaking down all of a plastic’s structure, this option specifically targets those resilient carbon-carbon bonds at a much lower temperature and with half the hydrogen gas pressure. The new catalyst is so stable that it holds up to infamous, contaminant-heavy plastics like PVC.

“Adding PVC to a recycling mixture has always been forbidden. But apparently, it makes our process even better,” Kratish said. “That is crazy. It’s definitely not something anybody expected.”

If proven to be scalable and efficient, the new catalyst could largely eradicate the need for painstaking plastic pre-sorting while also drastically reducing the amount of microplastics released into the environment every day.

Meet the Top 10 AI-Proof Jobs That Everyone Wants

https://gizmodo.com/ai-proof-jobs-a-robot-cant-do-2000651426

AI is rapidly scaling in the workforce and creating fears of an employment crisis, as workers and people entering the workforce try to figure out if their career is on the chopping block.

That quick pace is backed by emerging data. As a result, people are trying to find “AI-proof” jobs that can guarantee job security as companies around the world choose to automate tasks instead of hiring new workers.

Although no study can definitively say which occupations are 100% AI-proof and which are doomed to automation, a recent Microsoft study and its findings can shed a light on the matter.

A Microsoft study published last month measured how AI can productively apply to the common tasks of different jobs.

Microsoft researchers analyzed more than 200 thousand anonymized conversations from Bing Copilot, the company’s search engine chatbot, from January 2024 through September 2024 to see “what tasks users perform with a mainstream, publicly available, free-to-use generative AI chatbot,” the study says.

The study then developed “AI applicability scores” for these jobs, a number that represents the combination of which work activities people sought the most AI assistance for plus how successful these tasks were and their scope of impact.

There are caveats

Although the study shows which occupations AI can automate best, and those which it can’t do as well, Microsoft says that doesn’t necessarily mean that those jobs will be eliminated.

The AI applicability score highlights “where AI might change how work is done, not take away or replace jobs,” Microsoft representatives told Gizmodo earlier this month.

“Our research shows that AI supports many tasks, particularly those involving research, writing, and communication, but does not indicate it can fully perform any single occupation,” Microsoft said.

The data also does not imply that jobs with high AI applicability scores will have higher wages thanks to AI incorporation, the study noted, because the data does not include “the downstream business impacts of new technology.”

Read more about AI’s predicted effect on the corporate world from Gizmodo here.

Why companies automate

Microsoft believes AI can be used to augment these jobs rather than completely automating them.

But is that what corporate executives want? It’s tough to make a blanket statement on that, but early signs indicate that executives might be more pro-automation than not.

Increasingly, executives around the corporate world are voicing their expectations and desires to see AI cut costs across the workplace. This news has naturally led to a slowdown in hiring, particularly impacting early career workers in white-collar fields to which, as the Microsoft study also shows, AI poses the biggest threat.

“Artificial intelligence is going to replace literally half of all white-collar workers in the U.S.,” Ford CEO Jim Farley said at the Aspen Ideas Festival just last month.

Several executives have also already put into effect new hiring policies this year that ask managers to explain why an AI agent can’t fulfill the role before they can go ahead with hiring a new worker.

Just because you can doesn’t mean you should

AI can cut labor costs and increase profit for companies. But that is not yet a case for wholesale automation.

Although AI can automate some of these jobs, it doesn’t mean it can do a great job at it.

For example, Microsoft says that writers are in the top 10 for highest AI applicability. But AI-generated writing has been criticized far and wide, particularly for its bountiful copyright issues as AI feeds on the work of existing human writers to “create” new pieces.

The disruption of the labor market that is bound to follow the automation of certain jobs should also be a cause for concern.

Former Google executive Mo Gawdat said earlier this month that he believes this AI-driven labor problem is one of several aspects of the way we approach AI that is bound to lead to a short-term dystopia in the next 15 years.

Much like the Microsoft researchers that worked on the study, many other experts argue that the augmentation of AI into certain fields is a much better way to fuse AI into the economy for productivity gains than automation.

So what are the jobs?

Here are the ones most likely to stay human-run, the study says:

10. Tire Repairers and Changers

9. Ship Engineers

8. Automotive Glass Installers and Repairers

7. Oral and Maxillofacial Surgeons

6. Plant and System Operators

5. Embalmers

4. Helpers-Painters, Plasterers

3. Hazardous Materials Removal Workers

2. Nursing Assistants

1. Phlebotomists (aka healthcare professionals trained to collect blood samples)

AI works with data. So it is not surprising that the list overwhelmingly includes healthcare industry jobs, and blue collar work, both of which require specialized physical expertise rather than clear-cut data synthesis.

In the healthcare industry specifically, AI adoption has also been particularly slow due to limited datasets. Only less than 10% of surgical data is publicly available due to strict regulations.

The jobs that are at highest risk 

Microsoft also looked at jobs that it deemed had the highest levels of AI applicability. Those were, rather unsurprisingly, knowledge work occupations and sales roles, where AI is already being rapidly incorporated.

Here is the list of the top 10 jobs that have the highest levels of AI applicability:

10. Broadcast announcers and radio DJs

9. Ticket agents and travel clerks

8. Telephone operators

7. CNC tool programmers

6. Customer service representatives

5. Writers and authors

4. Sales representatives of services

3. Passenger attendants

2. Historians

1. Interpreters and translators

Google’s Browser-Based Video Editor Is Now Available for Free

https://lifehacker.com/tech/google-browser-based-video-editor-free

Google Vids is the company’s web-based video editor, and you can now use it for free. Up until now, Vids was available only for paying Google Workspace subscribers, but this move makes it accessible to everyone. The pitch here is quite simple: Vids is a simple video editing tool that integrates extremely well with Google Drive. You can use basic editing tools and templates for free, and if you’re a paying Google subscriber, then you can use its AI features, too. 

Before you get too excited about Google Vids, though, you should know that it’s not a replacement for professional editing software. It’s more intended as a good place to get started, a bit like what Windows Movie Maker used to be about 15 years ago. You can do a lot with Google Vids, but if you’re a professional, you’ll hit the limits of the app’s capabilities fairly quickly. The good news is that there are alternatives like DaVinci Resolve for those who want professional-grade editing software and don’t need to do their editing in a browser. But if that’s a bit overkill for your needs, Google Vids is still worth looking into, especially because of the new free tier.

Google Vids now has a generous free tier

Over the years, I’ve learned to lower my expectations for web-based video editing tools, but Google Vids is quite decent. My favorite thing about it is that if you have no idea how you want to present a video, it has several built-in templates to help you get started. For instance, there’s a template that lets you create a "year in review" style video. Within each template, you can insert premade scenes alongside your own footage. For instance, a sourdough prep template I found had premade scenes showing an ingredient list (with text you can swap out for your own recipe), someone prepping dough, someone making dough, and so on. 

You also have the option of importing a presentation from Google Slides and converting it into a video. It’s a great use of the app’s integration with Google Drive, and even better, you can also easily import pictures from your Google Photos account if you need still shots. There’s even a handy feature that lets you search stock photo/video websites to get filler footage.

The tools available for basic edits are also quite intuitive. Even as a novice, I was able to easily add basic animations for text or transition effects, and modify on-screen elements like the background. Google Vids also lets you easily search for royalty-free music to add to your videos, which is a nice touch. The best bit is that you can use Google Vids via any browser, not just Chrome. 

You can pay for AI integration

If you are a paying Google Workspace subscriber, then you can also use AI features in Google Vids. The basic editing tools remain the same, and all the AI stuff basically revolves around using a text prompt to generate ideas or videos. For instance, you can use a text prompt to generate a rough storyboard, or just ask Gemini to look at a Google Docs file to generate it even without a prompt. Vids also lets you throw in a script and generate an AI voiceover for your videos, and you have the option to choose from multiple types of voices.

Using Veo 3, you can also now make eight-second video clips from a text prompt, or convert still photos into video using AI. If that’s not enough, you could also input your entire script, and Vids will generate an AI avatar to read it out loud for you, with no restriction on time, over your other footage. I’ll presume Google has done its due diligence to not base any of these avatars on actual people—you can see a few avatar choices above—but still, it does mean that some of the talking heads you’re about to see online won’t resemble the person making the video at all. Be careful with what you assume is real.

SpaceX Just Sent the ISS a New Way to Stay in Orbit

https://gizmodo.com/spacex-just-sent-the-iss-a-new-way-to-stay-in-orbit-2000648211

The International Space Station (ISS) has been in orbit for over 26 years, housing astronauts at an altitude of 250 miles (400 kilometers) above Earth. But even at that distance, the space station can’t escape the drag of Earth’s atmosphere as oxygen molecules and other gases collide with it, causing it to lose altitude over time.

For the ISS to retain its status in orbit, NASA and its partners perform the occasional reboost maneuver. This is typically done using the space station’s own thrusters (which are tiny and relatively weak) or with Russia’s Progress spacecraft and Northrop Grumman’s Cygnus. For the first time, however, and starting in September, NASA will use SpaceX’s Dragon vehicle to help sustain the space station’s orbital altitude.

A boost kit in the trunk

SpaceX’s Dragon launched to the ISS on Sunday at 2:45 a.m. ET, carrying more than 5,000 pounds of supplies to the orbiting lab. The otherwise routine commercial resupply mission carried a little something extra this time around, a propellant system tucked inside Dragon’s trunk for a reboost demonstration.

Dragon’s boost kit will be used to maintain the altitude of the ISS starting in September through a series of burns planned throughout the fall, nudging the massive space station a little higher in its orbit.

The SpaceX spacecraft, while docked to the station, will use a propellant system that’s independent from the one used to fuel its own engines. Instead, the boost kit fuels two Draco engines in the spacecraft’s trunk using an existing hardware and propellant system design, according to NASA.

Dragon’s engines are not facing the right direction to pull off the boost maneuvers; hence, the need for the additional engines that are aligned with the velocity vector of the ISS.

The rear-facing engines are connected to propellant tanks filled with hydrazine and nitrogen tetroxide, which ignite when they come in contact with one another. When it’s time to give the ISS a little boost, the engines will ignite and lightly adjust the space station’s altitude in low Earth orbit.

Multiple reboost options

NASA and SpaceX tested Dragon’s ability to reboost the ISS in November 2024 through a demonstration that lasted approximately 12 minutes. Dragon successfully adjusted the station’s orbit by 7/100 of a mile at apogee, the point at which it’s farthest away from Earth, and 7/10 of a mile at perigee, when it is closest to Earth.

“By testing the spacecraft’s ability to provide reboost and, eventually, attitude control, NASA’s International Space Station Program will have multiple spacecraft available to provide these capabilities for the orbital complex,” NASA wrote in a statement at the time.

The Dragon spacecraft will remain docked to the ISS until December—the longest period for a cargo mission—in order to pull off the reboost maneuvers in the coming months. The boost kit being used on this mission is a smaller version of one SpaceX is currently developing for the space station’s final deorbit.

The ISS is due to retire by 2030, and NASA plans on using a Dragon spacecraft to perform a series of deorbit burns that will lower the space station’s altitude until it burns up in Earth’s atmosphere. Until the moment comes for its impending doom, the ISS will get to enjoy a little boost from Dragon.

Eating Plant or Animal Protein Makes No Difference When It Comes to Mortality

https://www.discovermagazine.com/plant-or-animal-protein-makes-no-difference-when-it-comes-to-mortality-47964

We all know that nutrition is one of the pillars of health. To live a long and healthy life it’s important to get the details right, and one ongoing topic of dietary research is protein. Like carbohydrates and fats, both the amount and quality matter.

Nutritional research is tricky, often relying on observational studies that offer hints but not definitive answers. A recurring debate is whether plant proteins are healthier than animal proteins. Researchers from McMaster University in Ontario recently set out to explore that question.

Their study, published in Applied Physiology, Nutrition, and Metabolism, looked at data from nearly 16,000 adults. Surprisingly, it doesn’t seem to matter whether protein comes from plants or animals when it comes to overall mortality, though animal protein showed a slight protective effect against cancer deaths.

Confusion Around Eating Protein

The recommended dietary allowance (RDA) for protein in Canada and the U.S. is 0.8 grams per kilogram of body weight per day. Another way to approach protein amounts is the acceptable macronutrient distribution range (AMDR), which is broader, at 10 to 35 percent of daily calories. Most people already fall comfortably within this range, often several times higher than the RDA.

Debate remains over how much protein is optimal, especially for older adults. Some studies suggest more protein supports muscle health and longevity, while others raise concerns. One study linked high protein intake with a 75 percent increase in overall mortality and a four-fold higher cancer risk in adults aged 50–65.

Interestingly, that risk disappeared when the protein came from plants, lending support to guidelines like Canada’s Food Guide, which favors plant protein. But instead of focusing on protein amounts, the McMaster researchers looked at usual amounts of protein, only differing in the source of protein.

“There’s a lot of confusion around protein – how much to eat, what kind and what it means for long-term health. This study adds clarity, which is important for anyone trying to make informed, evidence-based decisions about what they eat,” said study co-author Stuart Phillips, professor at McMaster, in a press release.

Plant vs. Animal Protein

To provide clarity, the team analyzed data from the Third National Health and Nutrition Examination Survey (NHANES III), which gathered dietary information from U.S. adults between 1988 and 1994. Close to 16,000 people, ages 19 and up, were included.

The researchers used advanced statistical methods, including the National Cancer Institute (NCI) method and multivariate Markov Chain Monte Carlo modeling, to account for daily fluctuations in protein intake.

“It was imperative that our analysis used the most rigorous, gold standard methods to assess usual intake and mortality risk. These methods allowed us to account for fluctuations in daily protein intake and provide a more accurate picture of long-term eating habits,” said Phillips.

Results showed no link between total, animal, or plant protein and risk of death from any cause, including cardiovascular disease and cancer. Even when both protein sources were analyzed together, the findings held steady. There was a hint that animal protein may slightly reduce cancer-related mortality but no significant relationship emerged for plant protein.

Protein That Promotes Health and Longevity

The takeaway? The data don’t support the idea that one protein source is inherently more harmful or beneficial for longevity than another. If anything, animal protein may be mildly protective against cancer deaths, but the difference is small.

As with all observational studies, the findings can’t prove cause and effect. Still, when combined with decades of clinical trial evidence, the results offer reassurance for people who enjoy a mixed diet.

“When both observational data like this and clinical research are considered, it’s clear both animal and plant protein foods promote health and longevity” concluded first author Yanni Papanikolaou in the statement.
