The original paper about microplastics in the brain seems to have a serious methodological flaw that undermines the conclusion that our brains are swimming in microplastics.
“False positives of microplastics are common to almost all methods of detecting them,” Jones says. “This is quite a serious issue in microplastics work.”
Brain tissue contains a large amount of lipids, some of which have similar mass spectra as the plastic polyethylene, Wagner says. “Most of the presumed plastic they found is polyethylene, which to me really indicates that they didn’t really clean up their samples properly.” Jones says he shares these concerns.
This is from other microplastics researchers. See this article. So before we panic about this, let’s wait for some independent replication and more agreement in the scientific community.
Microplastics are a serious concern, and we need to deal with plastic pollution. Let’s just stick to high quality science while we do that.
I haven’t seen any evidence that this is solvable. You can feed in more training data, but that doesn’t mean generative AI technology is capable of using that in the way you describe.
This article is 10 years old.
When you first boot up a device, most data on that device is encrypted. This is the Before First Unlock (BFU) state. In order to access any of that data, someone must enter the passcode. The Secure Enclave uses it to recreate the decryption keys that allow the device to access that encrypted data. Biometrics like Face ID and Touch ID won’t work: they can’t be used to recreate the encryption keys.
Once you unlock the device by entering the passcode the device generates the encryption keys and uses them to access the data. It keeps those keys in memory. If it didn’t, you’d have to enter your passcode over and over again in order to keep using your device. This is After First Unlock (AFU) state.
When you’re in AFU state and you lock your device, it doesn’t throw away the encryption keys. It just doesn’t permit you to access your device. This is when you can use biometrics to unlock it.
In some jurisdictions a judge can legally force someone to enter biometrics, but can’t force them give up their passcode. This legal distinction in the USA is that giving a passcode is “testimonial” because it requires giving over the contents of your mind, and forcing suspects to do that is not legal in the USA. Biometrics aren’t testimonial, and so someone can be forced to use them, similar to how arrested people are forced to give fingerprints.
Of course, in practical terms this is a meaningless distinction because both biometrics and a passcode can grant access to nearly all data on a device. So one interesting thing about BFU vs AFU is that BFU makes this legal hair-splitting moot: biometrics don’t work in BFU state.
But that’s not what the 404 Media articles are about. It’s more about the forensic tools that can sometimes extract data even from a locked device. A device in AFU state has lots of opportunities for attack compared to BFU. The encryption keys exist, some data is already decrypted in memory, the lightning port is active, it will connect to Wi-Fi networks, and so on. This constitutes a lot of attack surface that hackers could potentially exploit to pull data off the device. In BFU state, there’s very little data available and almost no attack surface. Automatically returning a device to BFU state improves resistance to hacking.
This is a terrible idea. It’s negligibly better than writing down the passwords, because it’s trivially easy to try every password represented on this card. Once someone has the card, your entropy is just two characters, which is the two characters you memorize for the site. In effect, you have a 2 character password.
One of the ways I do this is “spot the lie” when an ad comes on. Virtually every ad has some lie in it, even if it’s small. Buying this brand of car will make a sexy person like me (nobody cares what you drive). Altria Group is altruistic (they kill millions with cigarettes). Adopting a pet today will make you happy (Not everyone can care for a pet, and sometimes it’s miserable). A price of $4.99 is basically $4 (it’s really $5). I practice this, talking about why the ads exist and why they are effective, the biases they tap into. Everyone is vulnerable to manipulation like that. And then I extended that to some of the videos my kids watch. Why are the Ninja Kidz playing with that toy the entire episode? Because they were paid to do it. It’s just another ad.
Then that skill pivots to other things. Religion behaves the same way, selling itself to people. Conspiracy theories do this as well. And sometimes other people are doing the advertising right to your face, and they may not even realize it.
In short, equip your kid with the best BS detector that you can, and then let them find their way.
You can’t fight brainwashing by providing more facts. It doesn’t work. Brainwashing gives the victim mechanisms to reject new facts that contradict the false beliefs. The false beliefs become a part of a person’s identity, so it’s tied into self esteem and confidence. So that’s how you have to approach it: find ways to challenge the false beliefs that don’t also challenge their sense of self. For adults this is very difficult.
But for children, it’s easier. During the teen years children are trying on identities like they’re trying on clothes. Give you child a look at a good, comfortable identity. It should make them confident, give them a community they feel comfortable in, and not make enemies of the ones they love.
I find that scientific skepticism does this by giving people the tools to think rationally about the world, spot ways that the world tries to deceive them, and giving an understanding of why those deceptions are effective.
Apple Watch works well as a kid tracker if they’re old enough to wear it safely, and I think the privacy aspects are very good. It uses the FindMy network, and Apple can’t see the location. There’s a bunch of specifics here. Apple Watch used to require an iPhone, but Apple made it so you can add a kid’s watch to the family so it uses a parent’s iPhone instead.
