From Nature.com (emphasis added):
Here, we describe easily deployable hardware and software for the long-term analysis of a user’s excreta through data collection and models of human health. The ‘smart’ toilet, which is self-contained and operates autonomously by leveraging pressure and motion sensors, analyses the user’s urine using a standard-of-care colorimetric assay that traces red–green–blue values from images of urinalysis strips, calculates the flow rate and volume of urine using computer vision as a uroflowmeter, and classifies stool according to the Bristol stool form scale using deep learning, with performance that is comparable to the performance of trained medical personnel. Each user of the toilet is identified through their fingerprint and the distinctive features of their anoderm, and the data are securely stored and analysed in an encrypted cloud server. The toilet may find uses in the screening, diagnosis and longitudinal monitoring of specific patient populations.
tl;dr — Data gathering for toilets using biometrics of your anus. Got it? Okay cool.
The article itself is paywalled, as far too many academic articles are, but one Twitter user shared screenshots of this screening, diagnosis, and longitudinal monitoring technology:

We performed 410 fingerprinting [Ed note: butthole] trials from 10 participants … Among 11 participants, two video clips of the anus per participants were acquired from 7 participants, whereas one video clip of the anus per participant was acquired from 4 participants … As an input, individual frames of the anus from participant 1 were used for identification purposes.
A good toilet paper is hard to find these days, thanks to everyone's totally irrational coronavirus panic buying. But that's not the biggest problem for our butts.
No, worse is that alt-TPs are messing with our septic systems, which makes an even bigger mess for everyone.
My colleague Doug Mahoney has a great new blog post over at Wirecutter that explains why you shouldn't flush anything but toilet paper down your porcelain throne, and also recommends some handy alternatives (and disposal methods) in case you do have a problem finding those cherished rolls of soft white butt scoopers.
Toilet paper is very fragile and is designed to self-destruct in water with very little agitation. Tissues, on the other hand, are made to stand firm against a 100 mph sneeze discharging from your nose. Although the two products might have the same general look and feel, this video shows the difference in their durability. It takes less than 30 seconds of agitation for the toilet paper to be almost completely broken down. The tissue, however, remains fully intact. In plumbing, the bits of toilet paper can speed down the waste lines, but tissues remain big enough to catch on something, contributing to a clog.
Out of Toilet Paper? You Have Other Options. Just Don’t Flush Them! [Doug Mahoney / Wirecutter]

For a decade, people have been destroying public toilets across Tokyo. Over the last six years, vandals have broken 85 toilets just in Hikarigaoka Park. What a pisser. Now, Tokyo officials have commissioned ironworks Ito Tekko to construct iron urinals for public use. From SoraNews24:

People in Japan were conflicted, feeling both pride in the quality engineering of these urine collectors as well as shame that it has come to this.
“I know people who like to smash toilets won’t agree, but I think these are great toilets.”
“I had no idea so many toilets were getting broken.”
“I think we should deal with the underlying issues of toilet smashing first.”

Toilet aficionados and sewer connoisseurs never settle for boring bathroom fixtures. For a cool $16,500, you too could impress your guests with a venus fly trap urinal, just like Oto Cadsky. Read the rest
Paris-based artist Anastassia Elias created these papercraft cityscapes inside toilet paper cores. It was part of November's World Toilet Day, and it was commissioned to bring awareness to the sad state of toilet affairs in many large cities. Read the rest

Amir captured this video of O'Hare Airport's hygiene-freakout toilets that automatically and in a hands-free fashion wrap the seat in fresh, germ- and piss-free plastic film between each user. Read the rest

Latvian designer Kaspars Jursons designed the Stand, a combination sink/urinal, to address water shortages. The water flowing from the tap as you wash your hands also flushes the toilet. ""It is more suitable for hygiene than just a urinal and then guys who don't wash [their] hands," Jursons told NPR. The look reminds me of the Penal-Ware Comby, a stainless steel, suicide resistant toilet/sink combination designed for prisons. Unfortunately, that device doesn't use the sink faucet's water to flush. Read the rest

Toto, Japan's foremost toilet manufacturer, has made a motorized tricycle that runs on human crap. The saddle is a functional toilet, and if you can muster up enough colonic motility to keep up a steady stream, you could travel the world.
Toto makes some damned fine toilets, incidentally -- we went to rather a lot of trouble to get one of the Toto toilet-seat/bidet devices imported to the UK and converted to local voltage, and never regretted it.
Lisa at TokyoMango explains:
As the person drives, he can poop into the bowl, and that poop will be turned into fuel for the car. It's actually part of a campaign that Toto is running in an effort to reduce its CO2 emissions by 50% in the next 6 years. The motorcycle will be making its way from Kyushu to Tokyo over the next month (departing in six days). Very exciting! I'm not sure who's driving but I'm sure that, in addition to having a drivers license, they had to check his stool to make sure its healthy and fuel-worthy.
