Sometimes it can seem that no matter what you say, you can’t get through. Many times this happens because of a framing problem. No, not carpentry framing, but conversational framing. Have you had a conversation with someone where you’ve had a bad day and you just want to complain about it, but the person you’re talking with keeps giving advice? You just need to get these things off your chest so you can move on, but it’s like the other person keeps putting up these speedbumps in the conversation that slow things down and makes the conversation kind of awkward. You’re having a framing problem. You want to complain and then be done, and your friend thinks you’re having some problems and just need some advice.
These two articles are about this. This one at lifehacker points out how it happens. It references this other blog post at lesswrong. You should really read the lifehacker one, as it is a good introduction. The lesswrong one is more in-depth.
I’ve noticed this happening at home, where my wife wants to unload and complain about something, and I want to be useful and give advice. It turns out that giving advice is something that males really like to do. But it gets in the way when the other person isn’t looking for advice. I’ve found that if I can recognize when I have that urge to give advice and then think “does the other person want the advice, or do they want to unload” helps to keep me from being the speedbump person and inadvertently making the conversation difficult for both of us.
This kind of self-reflection on something I’m about to do (give advice) and then backing off when it isn’t appropriate can really be useful in lowering the friction in a relationship.
Yes, rats have been trained to drive.
Not actual cars, but small vehicles in a lab. They can control left, right, and forward. The rats learned to drive to get food. And scientists found that learning to drive seemed to reduce stress.
The ability of rats to drive these cars demonstrates the “neuroplasticity” of their brains, says Lambert. This refers to their ability to respond flexibly to novel challenges. “I do believe that rats are smarter than most people perceive them to be, and that most animals are smarter in unique ways than we think,” she says.
And there are neat videos of rats driving their “cars”.
Here’s another article that includes information on the two groups of rats involved, including that they seemed to enjoy just driving their cars even if there were no treats involved, but only if they lived with many other rats in an enriching environment.
Some scientists painted stripes on cows, and found that it halved the number of biting insects. This could help ranchers save money, and is healthier than spraying pesticides on cattle.
If you’ve noticed that the news system likes to report on things going wrong instead of the nice things that happen, you now have evidence for the reason behind it. Humans pay more attention to bad things than good things. This study is about a world-wide 17 country study on how people react to negative news.
For example, while statistically, we are safer now than in the past, people are more and more afraid of it because the news concentrates on the bad things, not the good things that happen. That just isn’t “news”.
Vantablack absorbs 99.96% of incoming light.
MIT scientists have accidentally made a material that absorbs 99.995% of incoming light. I wonder if BMW will bother making a car coated in it?
K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf star K2-18, located 124 light-years (38 pc) away from Earth. The planet, initially discovered through the Kepler Space Observatory, is about eight times the mass of Earth, thus is classified as a super Earth. It has a 33-day orbit within the star’s habitable zone, but it is unlikely to be habitable.
In 2019, two independent research studies, combining data from the Kepler space telescope, the Spitzer Space Telescope, and the Hubble Space Telescope, concluded that there are significant amounts of water vapour in its atmosphere, a first for a planet in the habitable zone.
So, first exoplanet in a habitable zone with water vapor in the atmosphere! Neat! But it’s around a red dwarf star, and tidally locked. So it’s not likely to be actually habitable by humans. Red dwarfs are small stars that last much longer than our sun. They tend to have too much radiation to let life as we know it evolve. Being tidally locked means the same side of the planet always faces the star, so one side is hot and the other is cold. Life as we know it could probably only live on the circular edge where the star is near the horizon.
Beaches in California used to have great biodiversity, but that’s gone down recently. There’s still lots of critters living under the sand, but there aren’t as many different kinds of things there anymore.
You have blood. Your dog has blood. Heck, spiders have blood (hint: it’s clear). And now so do robots.
Would you believe that a robotic fish has blood that is used for both hydraulics and energy? Well there is one. It looks like a lion-fish. And using this special blood instead of batteries let it last up to 8 times longer.

According to this news article, in places it’s cheaper to build a new utility-scale wind or solar farm than keep running a coal power plant.
