A student accidentally created a rechargeable battery that she says could last 400 years

"This thing has been cycling 10,000 cycles and it’s still going." ⚡️⚡️

Steve Zylius/University of California, Irvine.

UCI doctoral candidate Mya Le Thai has developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner added. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most. ”"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

Since her discovery, Mya Le Thai has gone on to a successful career as the Principal Scientist with the Enevate Corporation,

Thousands of people get lost in the desert every year, but these otherworldly solar beacons could save them

They look like save checkpoints in a video game, and they kind of are.

Solar-powered beacons in the Saudi Arabian desert guide lost travelers to water.

Chief among my worries as a kid was what I considered the high probability that at some point in my life I would be trapped in quicksand. It felt extremely important that I remember all the tricks and techniques for getting out — just in case! A close second would have to be getting lost in the desert and dying of dehydration. You absolutely had to watch out for those deadly mirages, where the light on the horizon bends in such a way that you're certain you can see water up ahead.

At least one of those fears was fairly well-founded. All jokes aside, the desert is an incredibly dangerous place. It turns out that thousands of people get lost and go missing in deserts across the world every year. The Sahara Desert, the largest hot desert in the world, claimed a staggering 8,000 lives alone in 2023. These aren't overly flippant explorers, for the most part. Many migrants fleeing conflict zones across the desert become lost and suffer a tragic fate while trying to navigate the 3.6 million square mile area. There are many things that make the desert deadly, but dehydration with no access to water is at the top.

A team in Saudi Arabia has been testing a new technology that could drastically reduce dehydration-related deaths in the country's Al-Nafud Desert, and it looks like something straight out of a video game.

Though the Al-Nafud desert is quite a bit smaller than the Sahara standing at about 25,000 square miles, it can still be daunting to cross. Most years, hundreds of people go missing with several dozen of them perishing in the process.

An explorer named Mohammad Fohaid Al-Sohaiman had a brilliant idea to help lost travelers find water. Having been rescued in the desert himself, even as an experienced survivalist and outdoorsman, he knew there had to be a better way.

“Many people lost their lives in the desert near water resources because they did not know that water resources were close to them,” he told Arab News.

The idea: Beacons made of laser light, shot directly into the sky near water sources such as water wells. These powerful lights could be seen from miles away and would be powered by solar panels, ensuring they never go dark.

The plan is to eventually install 100 of the beacons throughout the Saudi Arabian desert.

The program to install the life-saving beacons began in 2021. It's still getting attention and inspiring awe all over the world.

A recent viral Reddit thread highlighted the innovative laser lights, and users were impressed:

"Absolutely brilliant! The rest of the world should immediately begin to implement this system in their desert areas as well as open oceans where water, food and communication devices could be stored for boaters in distress."

"This is such an amazing idea."

Others joked to the beams look like "save points" or "checkpoints" in a video game. They're not wrong!

Some have criticized the beacons, however, claiming that the light pollution may harm the desert's natural environment and residents like nocturnal animals and insects.



The desert holds vast potential for solar power due to its massive open spaces and plentiful sunlight. In fact, solar farms are common in deserts all over the world.

However, there are a couple of limitations that stop us from covering all the world's deserts in solar panels and completely converting to solar energy.

First, people underestimate how destructive and harsh the desert environment really is. Sand is incredibly corrosive, especially when whipped around in high-powered sandstorms. Maintaining solar equipment in the desert is incredibly challenging and costly.

Second, we think of deserts as open wasteland, but that's a misnomer. They're actually incredibly biodiverse natural habitats, home to many different forms of plant, animal, bird, and insect life. The desert habitat is no less important to preserve than rainforests or oceans.

Third, while solar energy is generally considered incredibly eco-friendly, massive solar farms can actually put off quite a bit of heat. A desert-sized solar farm would emit so much heat that it could negatively contribute to global warming and have devastating effects.


In any case, the life-saving beacons are a genius idea and a fantastic use of solar technology. Once the program is fully rolled out, it could save dozens or even hundreds of lives every year.

Just imagine a similar operation conducted in the massive Sahara Desert, or even in remote stretches of the American southwest.

As one commenter stated perfectly, "Now this is the type of innovation for the future I can get behind."

"How to use a printer" satire perfectly captures our frustration with modern technology

There's a word for why everything that should be awesome by now seems to be getting worse.

Home printers are incredibly frustrating to use, and they aren't getting better.

Anyone who has ever printed a document at home knows the inevitable rage of dealing with your standard home-office inkjet printer. They're clunky, unreliable, and prone to a litany of problems—everything from drivers to ink cartridges to the WIFI is bound to malfunction at some point. And without a usable interface, they're extremely difficult to troubleshoot on your own.

The problem with printers is that they have been around since at least the 80s. And while the technology has improved in some ways, they remain incredibly buggy and difficult, and printer manufacturers have found infuriating ways to make them even more annoying and expensive to use. (Ink cartridge subscriptions, anyone?)

office space, printer, printers, home office, technology, profitsThe boys from Office Space knew how to handle wayward printers.Giphy

But YouTuber Gus Johnson is here to help. He's created a perfectly simple guide for anyone who wants to get their printer set up and begin printing documents. Let's go!

First, Johnson walks us through how to make sure our printer is turned on. It's on? OK, great! Now we're ready to print—well, after the printer installs the 18 mandatory driver updates.

Once those are all done, it's time to print. Except it turns out the ink is low—well, not low, but low-ish, which means the printer won't print until you replace all of the cartridges. And no, you are not allowed to print in black and white if your magenta is low, just so you know.

The cartridges, by the way, are not compatible between printers and often not reliably sold in stores. So, Johnson shows us how to order them online and then wait. Days later, now we're ready to print! Well, after one more new cartridge update installs, and of course given that you can figure out how to get your supposedly "wireless printer" to talk to your laptop.

Johnson's video is a gut-busting watch for anyone who's grappled with a home printer and been tempted to pull an Office Space on it with a hefty baseball bat. Watch the whole thing here:

- YouTubewww.youtube.com

Printers are a really complicated piece of technology. But that shouldn't let them off the hook. Most of the problems spoofed in Johnson's video are solvable. And that's exactly the larger issue.

The Wirecutter writes that "there is some amazingly complicated technology in your printer, including the printheads, the ink, and the mapping software. You take your printer for granted, but that box can cover a piece of paper in millions of dots of precisely located, color-matched ink in a few seconds," and that most manufacturers take a loss on the actual machinery of a printer, hoping to recoup the earnings via ink sales later down the road.

If printers were the only piece of technology that seem to get worse and worse, bleeding us for more and more money while offering a rapidly deteriorating product, maybe we'd be willing to spare a few tears for the poor manufacturers. But this is a global problem affecting practically everything we touch—from social media, streaming content, journalism, and even restaurants. We pay more or the same for something that doesn't ever get any better, and often gets worse!

There's a term for this phenomenon. It's officially called "enshittification," or platform decay.

Writer Cory Doctrow, who coined the term, describes the pattern like this: "Here is how platforms die: first, they are good to their users; then they abuse their users to make things better for their business customers; finally, they abuse those business customers to claw back all the value for themselves. Then, they die."

Bill Maher described Silicon Valley's approach to technology as, "If it ain't broke, f*ck with it."

- YouTubewww.youtube.com

Doctrow even mentioned printers specifically in a recent Medium post:

"They make printer-scanners that won’t scan unless all four ink cartridges are installed and haven’t reached their best-before dates. They make printers that won’t print black and white if your $50 magenta cartridge is low. They sell you printers with special half-full cartridges that need to be replaced pretty much as soon as the printer has run off its mandatory 'calibration' pages. The full-serving ink you buy to replace those special demitasse cartridges is also booby-trapped — HP reports them as empty when they’re still 20% full. ... HP tricks customers into signing up for irrevocable subscriptions where you have to pay every month, whether or not you print, and if you exceed your subscription cap, the printer refuses to work, no matter how much ink is left."

Ink is outrageously expensive, but the printer companies exploit copyright laws to make sure you can't buy third party cartridges. When that fails, they push out security updates that break compatibility with anything but their own ink cartridges. These kinds of offenses go on and on.

In other words, long ago it was very exciting that we were able to print our own documents at home. Initial innovations focused on making that process better and better. But we're long past that now and the problems with most home printers will probably remain forever, or as long as manufacturers think they can keep squeezing our wallets. They're not really incentivized to make a printer that actually uses 100% of an ink cartridge or reliably connects to WIFI—they just want to make sure we buy the next one.

Johnson's YouTube rant is so funny precisely because it's true, but also because it finds humor in the frustration we all share at this cycle of enshittification. If we can't get our $300 printer to reliably spit out a basic black and white document, at least we can all laugh at our shared misery.

7 mindblowing medical breakthroughs that could occur in our lifetime

One day soon, you might be able to grow new teeth. Seriously.

Canva Photos

My family has a history of Parkinson's Disease, so I always see the headlines that promise some major scientific breakthrough in regards to the disease based on small, lab-based experiments or trials run on animals. They give us a glimmer of hope but, far too often, these treatments never see the light of day. The road from promising idea to having a real treatment available for patients is extremely long and arduous. Most potential new medications and therapies don't survive.

But... things do sometimes happen! There are massive medical breakthroughs being achieved all the time. Sometimes it's a new discovery, sometimes it's a successful clinical trial, and sometimes it's the fruit of all that labor finally becoming publicly available to people who need it the most. For example, an RSV vaccine just became available in 2023 for the first time. A powerful non-opioid pain killer was approved in 2024. A new drug came out to treat schizophrenia that was completely different than anything that had come before. Progress is being made every single year.

In our lifetime, say the next five to 20 years, we could see unbelievable advancements in treating certain medical conditions. Here are a few pretty amazing potential developments that are on the horizon.

1. Growing new teeth

Unlike sharks, humans are known to grow only two sets of teeth, our baby teeth and permanent adult teeth. If one gets knocked out or lost due to decay or infection, you're out of luck!

But researchers say growth buds exist in our gums for a third set, and scientists in Japan have had success in activating them to grow naturally. It could be a major gamechanger that could one day replace dentures and prosthetics. The team has moved onto human trials and has a target date of having a drug ready by 2030.

2. Cancer vaccines

Medical scientists have made amazing strides in cancer research, especially in the field of vaccines.

Did you know that lung cancer is considered to be the most deadly of the bunch? A lung cancer vaccine could be available very soon. If a cancer vaccine sounds odd, think of it this way: Cancer can be treated by chemotherapy and radiation, but there's always a chance of it coming back. People who have survived cancer could theoretically take the vaccine and massively improve their chances of reoccurrence.

A similar vaccine is showing promising results in clinical trials for pancreatic cancer.

3. Better treatment for Alzheimers

Alzheimer's Disease is one of the most destructive and heartbreaking conditions imaginable. It's also extremely difficult to treat, with most currently available therapies and medications focusing on slowing or temporarily relieving certain symptoms.

One new avenue scientists are exploring is a vaccine that could target a protein called tau, which clumps together and tangles up crucial neurofibers that deliver information in the brain. One such medication aims to activate a patient's immune system and produce "a strong antibody response against both pTau and its harmful aggregated form." The drug was recently fast-tracked by the FDA and has shown promising results in human clinical trials.

Another relatively new development is the availability of monoclonal antibody treatment, which helps slow the progression of the disease. Currently, the treatments are not particularly cost-effective but may become moreso in the near future.

4. Breakthrough treatment for Huntington's Disease

Huntington's is a fatal central nervous system disorder that shuts down key brain functions in patients like speech, walking, and cognitive function. Some of the symptoms can be treated but, so far, little can be done to slow or stop the progression of the disease.

However, a new drug known as PTC518 was recently fast-tracked by the FDA due to promising results in clinical trials. It attacks mutant Huntington protein in blood cells and in cerebrospinal fluid and has been shown to improve symptoms of the disease in a 12-month trial run. What's especially exciting is that this drug attacks the disease itself rather than just treating symptoms at the surface level.

5. Targeted viruses that kill antibiotic-resistant bacteria

Bacteria is getting smarter and evolving. Antimicrobial resistance is a grave threat to the global population as well-known antibiotics become less effective against infection and new antibiotics are expensive and difficult to develop.

(If you've ever dealt with a staph infection, you know how scary it is when drugs just... don't work.)

This is where special viruses, called bacteriophages or just phages, come into play. These viruses selectively target and kill bacteria, and were actually first used about 100 years ago. Scientist are coming around to using them again. In select settings, they've proven to be incredibly effective against resistant infections, but will need more testing before they become widely available. However, it's definitely possible that this become a viable alternative to antibiotics in some cases in the next few decades!

6. Synthetic and bioprinted organs

There are simply not enough donor organs going around for all the people who need a healthy liver, heart, or kidney.

Luckily, incredible strides have been made in creating artificial organs that can function like the real thing. A man in Australia just lived for 100 days with a titanium heart while he awaited a transplant! And bioprinting technology – quite literally 3D printing using real tissue and living cells — has the potential to create new working organs from scratch in the near future. Genetically modifying animal organs to function in humans temporarily or maybe even permanently has also come an extremely long way and is a process that will drastically improve in the coming years.

7. A one-pill cure for Hepatitis B

Hepatitis B is a potentially fatal infection of the liver that affects hundreds of millions of people worldwide. There is a safe and effective vaccine available to some people, but it's only preventative and won't treat active infections.

A research team in Israel recently discovered that a low dose of well-known chemotherapy drug, Curaxin-137, completely destroyed a crucial and mysterious protein that the Hepatitis virus depends on. The testing was done in a lab setting, so the next step is clinical trials. The team hopes that one day in the not-so-distant future, patients could take a single dose and completely eradicate the virus in their system. That's about as close to a miracle-cure as you can get!

Not all of these potential breakthroughs will come to fruition, but it's pretty amazing to dig into the advancements and discoveries that are being made every day. This list is just scratching the surface, to say nothing of robotic surgeons that will make major surgeries less invasive, new treatments for baldness, nanotechnologies that can deliver medicine to specific parts of the body, and more. Ultimately, good news is coming relatively soon for people who need it.
