Swarms of tiny robots remove microplastics from soil and water in lab tests.

Swarms of tiny robots remove microplastics from soil and water in lab tests.

Scientists from the Czech Republic have created microscopic cleanup robots that successfully removed microplastics from both soil and aquatic environments in the lab. Details of their work are published in the journal npg Asia Materials.

To build the robots, researchers started with microscopic MXene particles made of ultrathin, stacked layers. The material has a large surface area and surface chemistry that help it attract and hold plastic. They then coated the particles with magnetic nickel nanoparticles so rotating magnetic fields could drive the tiny robots.

Then came the testing phase. The team placed swarms of these microbots into water and soil samples contaminated with plastic. The externally generated magnetic fields made the robots spin and tumble through the liquid and squeeze through tiny water-filled gaps in the soil.

"In soil environments, the microrobots can navigate through water-permeated soil microenvironments, actively disrupt microplastic entrapment within soil matrices, and extract them," the study authors commented in their paper.

As they moved, their sticky surfaces collided with microplastics, binding to them and dragging them along. The researchers then used a magnet to pull the microrobots, along with their trapped plastic cargo, out of the samples.

They performed well. In water, they removed about 94% of test polystyrene particles and 89% of PET (polyethylene terephthalate) in around an hour. In the model soil, they removed about 81% of the polystyrene and 72% of PET. This outperformed the same MXene material used without magnetic motion, which relied on passive adsorption rather than actively moving through soil and water.

While the results were promising, the tests were carried out in a lab. Field trials will be needed to evaluate how well the approach works under real-world conditions. There are also potential risks that will have to be addressed, such as leaching metal ions and possibly incomplete magnetic retrieval. However, the team believes its microrobotic platform could be valuable in the years to come.

My father said he thinks I'm "just confused" after I spent $1000 + attending his second wedding.

I've been dating and fucking/getting fucked by men for 6 years. I brought my fucking ex-boyfriend to the wedding as a friend for fuck sakes and he thinks I'm confused?!?!

I already disliked him because he didn't try to save the relationship between my mom and him. He just gave up and allowed my brother and I to be raised in a single parent household. Then he found another woman with 2 boys and decided he'd date her along with be a better father for her sons.

I've been trying to reconnect/ keep in contact with him because I don't know much about him as he only visited twice between when i was 12 and 18. But he did help me out in my first couple years of university.

This month he decided he was going to marry his girlfriend and invited my brother and I out. My brother is broke so I paid his way thinking I'd have a nice vacation and visit with my Dad. I paid for the hotel, the gas and the food. I asked my Dad if I could bring my friend, who he knows I used to date, he said he didn't care. My friend needed out of town and I thought I'd be fun.

The wedding was hilariously bad and the reception had no dancing because the Bride insisted on the slowest country music that you can only really shuffle back and forth to. So my friend and I, along with everyone else just drank. My Dad talked with his brothers, his friends, not once did he approach me. When I told him my friend and i were leaving the reception, after being there for 3 hours, my Dad made a comment along the lines "Oh come on man you never visit me". I bit back a harsh reply about him being the parent between the two of us and said it was due to the music being too slow.

My brother stayed and joined my Dad at the after party. It was at the after party that my Dad decided to share his thoughts about my sexuality. He tells my brother while they are drinking 1 on 1 that he believes I'm going through a phase and am just confused. I don't know why the fuck he didn't realize my brother would tell me, as if my brother owes him anything enough to keep it a secret.

Fuck you Dad, i left details in here with hope you see this. I thought we might be able to form a relationship but I'm so fucking done being the only one putting effort into it. And if you can't respect my choices when I'm a grown man then I'm done chasing after you. I don't need you in my life, although it would have been nice to know you.

The "Don't team up on a gen" idea has to be killer propoganda + other rage.

This guy is specifically getting called out in a post because there was two gens we could have finished together while someone was being chased. Instead he constantly kept jumping off as I got on and went to search for another gen. Even when we were down to 2 gens he refused to team up. We all ended up dying.

I'll tell myself this was for some sort of achievement or challenge and it isn't how he normally plays because he spent more time looking for gens rather than working on them.

Fellow survivors I promise you it's worth rushing the rest of a gen rather than wasting time searching for a new one ESPECIALLY when killer is in chase.

MAYBE the "Don't team up on gens" applies for the first gen just to spread pressure. But once the game has begun, work with your teammates to speed through gens!

I loooooove getting lectured for speaking my mind to my parents

I'm a grown ass man talking to a grown ass woman, expressing my frustration and suggesting solutions to our current living dynamic. What do I get in response?

Multiple paragraphs about how she could have been a worse mother. A paragraph saying she is trying her hardest and I shouldn't mind being her only support now that she is getting back on her feet. Never mind it was herself that allowed her life to get this bad.

Fuuuuuuuuuuck I fucking hate this goddamn predicament. I almost wish she was a worse mother then it would be easier to cut her off. But nope she had to be a loving enough mother that I feel the need to help while also being an incompetent adult whole requires help.

Every fucking day I wonder what it must be like to grow up with parents who actually have a plan for life other than winging it. I swear its like I'm the 50 year old and she is the 20 year old.

If your grocery store does price matches, download the Flipp app

It's free to use, you plug in your postal/zip code and it finds flyer deals from all over your area.

I live in a town of ~2500 off the highway. We have two grocery stores and prices are higher than in the city. But one of the stores price matches to places in the city which has a population of 75k and is ~200km away.

Get the flipp app, ask if your store price matches and what distance they match up to.

It takes more preplanning but it has saved me hundreds of dollars since I started using it this year.

P.S if you live in a big city download the "Too Good To Go" app. It's for restaurants to reduce food waste. You can get food that is within 24hours old for fraction of the original cost. Not great for picky eaters though as most of the bundles are random.

As a paramedic I want to respect Cops but some officers make it really difficult.

I live in rural, northern Canada in an indigenous dominant town. I interact with RCMP on calls all the time.

My biggest complaint about the RCMP is how often officers get rotated and how my community seems to only get rookie officers. They never seem to stay long enough to learn the community or how it's inhabitants live.

I will say I have worked with some amazing officers. One in particular has shown amazing de-escaltion techniques time and time again. But he is a senior officer and has a permanent placement in town.

These new, young officers? Fuck do I just want to slap them across the face sometimes or just sit them down and ask them if they realize what job they are working.

The way some of them treat my indigenous patients gets my blood boiling. The condescension, the mistrust, the assumptions, and the lack of professionalism in front of the public is insane.

I'll give you the example from tonight. I get a call at 1am for a man unconscious on the road. We get there, rouse him and learn he is walking to the indigenous reserve about 2 hour walk out of town. He was abandoned in town and didn't have money, or anyone to call. He's had some alcohol and his BGL is low. He doesn't want to go to the hospital as it will strand him further away from home. So I give him some glucose gel packets and spend ~hour with him until his BGL is at an acceptable level.

Now the RCMP shows up due to the severity and circumstances of the call. As I said the patient has no way home other than walking.

I decide to ask the RCMP officer (maybe 25yo) if he can drive my patient the rest of the way (~40 minute drive). This fucking officer had a good 10 second tantrum! Quietly cursing to himself and bitching about the guy. I really wish I could remember his exact words because they struck me as extremely childish. Mind you this is about ensuring a guy gets shelter for the night and isn't left to walk a highway. I ended up walking away from him and going back to my patient as he made a call to his supervisor.

Unknown to me, the officer asked my partner if we could just take him, my partner told the officer that the patient refused. Officer asked if we could try convincing him harder. Then the officer asked my partner if we could just restrain the patient and take them. Regardless of if it was a joke, I made a report about this because he's suggesting a gross abuse of power.

The officer finally realized he was actually going to have to serve his community, and talked with my patient. He got some names of the patients family and called around until he was able to get ahold of a family member.

This POS officer then says to my patient in the most condescending tone "You have a very nice brother, he's agreed to take you in tonight, I'll drive you there. You be nice to your brother tonight" which looking back isn't that bad but the tone he used!

Officer, this is is 38yo man who you are talking to like a child. I wish I could say this was just a cop issue but I also notice and get ticked off by onscene immaturity and unprofessionalism from coworkers.

As a 23yo medic I think the thing that drives me insane the most is feeling like the most mature person in the room while also being the youngest 🙄

This is walking a line but I want to talk about the whole "landback" idea for indigenous peoples.

First I want to start put by saying I am a white Canadian born and raised in BC, I've live in a town that has 5 indigenous reservations around it for over two decades. I have dated indigenous men. My school was over 50% indigenous. My first roomates were indigenous. I have nothing against the average indigenous person and find their culture more atuned to my soul than chirstianity. Many from my experience are humble and kind. But i hear this radical idea online about giving the indigenous more land or more control over Canada. I think most of the people who say this have never lived in a reserve town.

There are 619 indigenous bands in Canada. 43 of them have the jurisdiction to have law-making powers over their internal affairs, health, education, land management, and social programs, and reduce reliance on federal administrative funding. These 43 set an example and are some of the most well maintained nations. However many of them still deal with claims of corruption.

I'm not saying that Canada's politicans are uncorruptable. We are all human, all of us are susceptible to greed. But Canadian municipalities have higher scrutiny when it comes to audits and financial transparency. It also comes down to skill sets - the average Canadian town has people with more experience and more knowledge on running a town/area than the average indigenous band.

I'm not saying this is the fault of the indigenous bands. But if more people knew how some indigenous bands handle day to day issues on the reserve, they'd be less keen to give them more control over their daily life.

As a paramedic I love telling people who ask about my worst calls.

Patients and bystanders love to ask "what's your worst call" whenever there's a long transport time or even just out and about when they realize you work EMS.

Loads of paramedics hate bringing up the trauma. I haven't been affected by my calls yet, and i find the bad calls more cool than traumatic. I love telling people my worst calls and watching their enthusiasm switch gears.

They always start so joyful, just looking for an easy topic of conversation. Then I start telling them and that cheerfulness turns into empathetic and concerned looks.

I always think to myself "Oh are my most traumatic calls, too traumatic for you? Kinda a buzz kill to hear about the worst days, huh?"

They either end up cutting in and changing subjects or stay quiet for a little while after.

So just a PSA. Don't ask a paramedic Healthcare provider what their worst case was. If you do be prepared to hear some shit.

For anyone wondering my worst call (so far) >! A guy lost control of his truck and drove into the ditch, colliding with a chain link fence. The metal pole (about 1/2 - 3/4 inch diameter) on top of the fence skipped over his hood, pierced the windshield and penetrated the guy through the chest, right side. The pole ended up going through him and stuck into the backseat. He ended up surviving and I saw him walking around a few days later!<. Tame by a lot of standards but I work rural EMS.

If you work in healthcare it should be a crime coming to work sick.

I'm a paramedic and the amount of my coworkers who refuse to book of when sick is frustrating! Especially when they always pull the "would you mind if I drive, I don't feel well" if you don't feel well you need to book the fuck off.

We rotate between driving and attending every day, I shouldn't be forced to attend multiple days in a row because you refuse to stay home!

They always say they can't book off because they need the money, meaning i have to risk getting sick and missing work because they don't budget properly.

I'm so angry right now I wish I had the words to perfectly sum it up. It's just the entitlement of coming to work in a healthcare setting, while contagious because you can't be bothered to save money, drives me insane.

If I had more years on the job I'd be more comfortable telling my coworker to book off. But I'm going to look through the policies and see what the rules are surrounding this. I'm not going to let this slide again, next time some tries to dodge their job because they are sick I'm just going to tell them to go home.

I (23) reached the milestone of being finacial independent from my parents.

My entire life up to this point I have been taken care by someone else. Whether it was for housing and food or car insurance and clothing. September 2024 i got started in a good paying career.

My phone plan was the last thing being paid for by my Dad. Two months ago I was happy to tell him to take me off his plan when I bought myself a new phone

It's such a relief standing on my own two feet financially. Especially because I don't have a good relationship with my Dad, now I don't have to worry about offending him and being cut off.

I'm thankful for my job and happy that I am able to start investing right away for the day where I no longer have to work!
