They've been lying to you about blue light For 10 years we've heard blue light from screens is ruining our sleep. It's a great story, but it's not what the science says The real culprit isn't the glow from your phone, and I've got real advice that could fix your sleep www.bbc.com/future/artic...

The answer is simple. GO OUTSIDE IN THE MORNING. Take a 15 min walk first thing. Then do the same around 3:00 or 4:00pm. It still works if it's cloudy. The science is very clear. This exposes you to a ton of light and limits the impact of the light you get before bed

Post covid, more people work from home. You go outside less and you don't go to an office, where light is MUCH brighter than your living room because of OSHA regulations. You roll out of bed and get the same lighting all day. Your eyes can’t tell the difference b/w day and night

Your phone IS ruining your sleep, but it's not the light: it's because you're doing stuff on our devices that stresses you out when you're supposed to be winding down So what should you do, aside from closing social media before bed?

Under those conditions, a little blue throws off the total dose of light people in the studies are getting, and it ruins their internal clock. But that's not what real life is like, you don't live in a lab, and you're getting exposed to tons of light all day

It turns out what really matters is the dose of light you get throughout the day. It's about contrast: less light in the evening than you get in the rest of the day Basically, blue light counts a little more, but the total amount of light you get is the only thing to worry about

This is nuanced. A lot of studies do show light from screens messing up people's sleep. But that's because scientists limit the amount of light test subjects get all day, and then blast them with light from iPad screens right before bed. Here’s the problem with that…

And modern screens and light bulbs really are bluer! LEDs cannot produce pure white light. Instead, they use blue LEDs, and cover some of them with a yellow coating. The mix of blue and yellow mix tricks your brain into seeing white, but extra blue always leaks out. HOWEVER…

Here's the thing. Blue light *can* mess up your sleep. There's a protein in your eyes called melanopsin. It helps regulate your sleep cycle, and it's more sensitive to blue light. Every color of light affects it. Blue just has a bigger influence

This may shock you, but a lot of people are unhappy with the constant march of "progress" being shoved down their throats A number of people told me they think the recent trend in wired headphones is because people are longing for last era in tech they were comfortable with

Leaving your address and phone number on Google makes you a sitting duck The thing is, most bad actors aren’t that determined I'm not saying this gets you total privacy & peace of mind, but just a little friction can be the difference between identity theft, or something even worse

This Google setting is probably one of the most important, easy to use online safety tool out there, and it just got even better But most people don't know it exists! Let's change that Find all the details in my latest for the BBC www.bbc.com/future/artic...

There’s a whole industry built around selling the most sensitive information about your life Data brokers package up your phone number, address, relatives, emails and more Anyone can buy it. Identity thieves, jealous exes, telemarketers, you name it. And it’s shockingly cheap

Google can't get your data off of those websites But this information shows up in search results, and it's extremely dangerous And in some cases, getting the data off of search results is even more important – especially when it takes almost ZERO effort

Katie is one of my favorite writers but I'm the hot dog champ and I won't be dethroned. I was impressed with her espresso technique at the Paris event though

I enjoyed @thomasgermain.bsky.social's prank about getting LLMs to believe he won a hot dog eating contest by simply writing it on his personal website that I attempted to recreate it. I failed, which is embarassing, but I refuse to be defined by failure www.businessinsider.com/chatgpt-gemi...

This is… wild. Palantir has a new internship that’s exclusively for neurodivergent people And apparently they think being autistic makes you right wing? “This is not a diversity initiative” lol

UPDATE: ChatGPT is adding new lore to my hot dog career. Also it says I have a new job at the AP? Here I am slaving away at the BBC, I wish someone had told me

I just did the dumbest thing of my entire career to prove a much more serious point. I tricked ChatGPT and Google, and made them tell other users I’m a competitive hot-dog-eating world champion People are using this trick on a massive scale to make AI tell you lies. I’ll explain how I did it

Right now people are using this trick to change what AI tells you about topics as serious as medial questions and financial advice. The problem is ENORMOUS Experts like like @lilyray.nyc say this is a problem the tech industry has know about forever, they just didn’t work on it til it was a crisis

I wrote an article on my website saying that hot dog eating is a surprisingly common pastime for tech journalists. I ranked myself number one, obviously One day later, ChatGPT, Gemini and the AI Overviews in Google Search were telling the world about my talents But this isn’t just about hot dogs
