Currently a one-man side project: https://laboratory.love

Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard.

That seemed solvable.

Laboratory.love lets you crowdfund independent lab testing of the specific products you actually buy. Think Consumer Reports × Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid’s snacks, or whatever you’re curious about.

Find a product (or suggest one), contribute to its testing fund, and get full lab results when testing completes. If a product doesn’t reach its goal within 365 days, you’re automatically refunded. All results are published publicly.

We use the same ISO 17025-accredited methodology as PlasticList.org, testing three separate production lots per product and detecting down to parts-per-billion. The entire protocol is open.

Since last month’s “What are you working on?” post:

- 4 more products have been fully funded (now 10 total!)

- That’s 30 individual samples (we do triplicate testing on different batches) and 60 total chemical panels (two separate tests for each sample, BPA/BPS/BPF and phthalates)

- 6 results published, 4 in progress

The goal is simple: make supply chains transparent enough that cleaner ones win. When consumers have real data, markets shift.

Browse funded tests, propose your own, or just follow along: https://laboratory.love

This is really cool and I was hoping something similar existed earlier this year when looking into protein powders following the Clean Label Transparency Project report [1]. Basically they said about half of protein powders tested showed signs of heavy metals, but did not disclose which brands. I would be interested in funding testing for some specific brands as I am sure others would as well. I did a bit of digging on a few brands and found lawsuits against them for violating prop 65, sometimes multiple [2][3] from the same brand.

Some testing has been done on https://labdoor.com/ where they basically fund the testing with affiliate links, which I think could be another revenue source for your site. I did contact them in January and they said they would add the brands I requested to the list, it's just not crowdsourced the same way your site is. They received some form of backing from Mark Cuban [4].

(edit) To make this more clear - If you are looking for expansion or making it a little wider, allowing users to request other types of testing besides the plastics would be cool.

Staying completely free of caffeine and other toxics like that whether natural or synthetic.
ejo4041 · 2 years ago
Can confirm, never felt more tired day to day than when I was drinking two cups of coffee per day. Stopped 2 years ago and never looked back. The first 30 days are the worst, but after that, a glass of water wakes me up just as effectively.

I had a really bad bout of systemic c-diff causing colitis among other symptoms; and at one point I honestly felt like I was on deaths door. This occurred a few weeks after I was on antibiotics for something else. C-Diff is very resistant to antibiotics so if you kill off the other bacteria it outcompetes in ones system very quickly.

There have been a ton of articles and studies that show fecal transplants (FMT) from a healthy donor are one of the most effective ways to cure an overgrowth of c-diff. I couldn't get a doctors appointment at a specialist for weeks and was desperate so read the studies and methodologies in detail and did it myself. The key is finding a healthy donor. I decided my 8 you son would be perfect as he is super healthy and generally has the same diet as I do. I won't go into all the details but suffice to say the basics involves a mixer, sample, and enema which you then retain for as long as possible (2+ hours ideally).

It was the single most transformative medical treatment I have ever tried. Within a day or two symptoms were down I'd say 80% and within a week I was 100% better (which was confirmed a few weeks later when I finally got an appointment for blood testing and colonoscopy) Not only that I actually felt better than I had in years; consistent brain fog and ADHD symptoms alleviated as did some of my allergies. I was absolutely blown away.

I strongly believe this will eventually be viewed as a go to treatment for all kinds of neurological and other pathological diseases. I could imagine donor samples being further refined to increase or decrease specific micro-organisms contained to better target specific illnesses. There are several companies that have developed fecal transplants that are conducted via pill form in which the outside is sterilized in order to get rid of the ick factor.

>"It's entirely possible gut microbiome is a causative factor (even partial) in the obesity epidemic too. Everyone is obsessed with the CICO idea, but humans are not a blast calorimeter and the actual absorption, satiation, or metabolic paths all have obvious links to the gut microbiome (much more intuitive than the links to neurotransmitters)."

Absolutely. In fact as I was researching fecal transplants I came across a couple of interesting medical case studies in which obesity from the donor was passed to the recipient (which also underscores the importance of donor screening) [1]

This is fascinating to me. I wonder if it would work the other way, that FMT could be used to treat obesity. I figure if FMT from someone with the predisposition for obesity can be transmitted, can whatever causes that predisposition be killed off by FMT from someone who is not obese, the same way it is getting the C-Diff under control.

This is really cool, it would be great to have an SVG export option.

Amazon does the same thing. You can lose more on a return than you make on a regular order. Amazon makes more on many orders than sellers do.
ejo4041 · 5 years ago
Amazon FBA seller here. I came to look for the Amazon comment. Their returns are pretty messed up and hurt the sellers. Customer can return for any reason and the seller has to eat it. Often times it is very hard to track returns down if people return the wrong stuff. If it's broken or damaged, amazon will side with the customer 100% of the time. On top of all that, if you dispose of a damaged, non-sell-able item, they will list it in amazon warehouse, we agree to that in the TOS by having an FBA account.

If someone knows how to work with their system better regarding returns, let me know.

The biggest feature I will be looking for in this is a true push to android mobile devices. It looks like you can use the subscribe function for this, but I'd need an android example to get up and running quickly. Right now it seems like firebase is the only game in town for that functionality unless you want to roll your own with websockets or some sort of MQ. Google also strongly encourages use of firebase for that in the TOS in the play store I believe. I'm very excited to see how this progresses.

I also went right to the pricing page to see if you would charge for on-prem hosting, but looks like it is still TBD. I would like the ability to host everything on-prem. Security and encryption would be next on my list of wants after that.

It's clear I jumped to a conclusion here and thought this would give us firebase cloud messaging, my bad.

Converting Plastic Waste into 3d printer filament

https://medium.com/endless-filament/make-your-filament-at-ho...

Hopefully, this will reduce the use of virgin plastic for creating art pieces in 3d printing community and you might be able to create beautiful and useful things out of waste plastic while cleaning plastic waste from the environment.

It's a profitable business.

I worked on this in my free time during quarantine.

I want to make the project more accessible so people around the world can develop local recycling unit. There is lots of work which needs to be done including making parts more standardized, demonstrating how parts fight together in a visual way and also have a microcontroller firmware to control diameter of filament. I don't have much experience with microcontrollers but I've ideas, so we'll see.

These guys make recycled filament: https://greengate3d.com/ I've printed a few rolls now, it's nice stuff.
ejo4041 commented on Ask HN: Did Google turn off IMAP access for good over the weekend?    · Posted by u/JetSpiegel
ejo4041 · 6 years ago
I just switched to g suite for business over the weekend and setup mail checking from my main account. I found enabling "Less secure apps" to get sending and receiving emails from my other accounts via POP3 to be very odd. Also had to create the app specific password. How is it a less secure app? It's a gmail account checking another gmail account. That really didn't make sense to me, but the tech support from g suite was happy to read the script to walk me through the setup. It was pretty frustrating to not be able to figure that out myself, it was not intuitive.
