Of note, this color change is sensitive to even super low levels of radiation that are just considered part of modern life – like cigarette smoke and car exhaust. That said, it is a useful monitor because it grows in many climates and shows exposure within just a few days.

Not to critique evolution, but I would think orange and black stripes wouldn’t be as good for camouflage in a forest as, say, green and black would.
It turns out a lot of animals can’t see the difference between orange and green! Elephants, for instance, have dichromatic vision (two types of cones, rather than three like most humans.)
Check out this diagram from ResearchGate. It deals with the color vision of horses, who are also generally dichromatic. (I think, though I’m not sure, that zebras would have the same color vision as horses.) See how orange and green look to them?
Not to critique evolution but I think prey animals should be better at telling when their predator is dressed like a traffic cone.
It doesn’t matter what zebras see, because tigers are not native to Africa and do not naturally hunt zebra. Tigers are Asian and mostly hunt animals like deer, elk, and buffalo. These aren’t animals with great color vision. They don’t need to have it because they don’t eat fruit and so don’t need to know when the berry is ripe vs when it’s not. Good color vision is too expensive to have if you don’t need it. Deer put their vision stats in a wide field of vision that is sensitive to motion, low light capabilities, and possibly seeing UV light. They don’t have great color and lack a lot of acuity, but have a great sense of smell and good hearing. That’s way more useful if you’re prey. Deer see well in the blue end of the color spectrum and less well in the red. This makes sense because deer are most active in the dawn and dusk periods, when there is more blue in the light. Tigers are taking advantage of deer eyesight by being orange.
We see tigers are being obviously colored because tigers are fruit colored to our tree ape brains.
I don’t know what the best part of this is: implying that deer chose their attributes on a character sheet, or the fact that we get to see tiger colors because they look like a snack.
a “hypothesis”, or a “science headcanon”,
I’m just going to die laughing a little bit.
dont you just love capitalism..
Black Mirror predicted this we are all goona die
my god but I get mad when someone flippantly dismisses important scientific progress because you can make it sound dumb by framing it the right way.
For a start, of course a lot of science sounds dumb. Science is all in the slogging through the minutiae, the failures, the tedious process of filling in the blank spaces on the map because it ain’t ’t glamorous, but if someone doesn’t do it, no one gets to know for sure what’s there.
Someone’s gotta spend their career measuring fly genitalia under a microscope. Frankly, I’m grateful to the person who is tackling that tedium, because if they didn’t, I might have to, and I don’t wanna.
But let’s talk about why we should care about this particular science and spend money on it. (And I’ll even answer without even glancing at the article.)
Off the top of my head?
- -advances in robotics
- -advances in miniature robotics
- -advances in flight technology
- -advantages in simulating and understanding the mechanics and programming of small intelligences
- -ability to grow crops in places uninhabitable by insects (space? cold/hot? places where honeybees are non-native and detrimental to the ecosystem?)
- -ability to improve productivity density of crops and feed more people
- -less strain on bees, who do poorly when forced to pollinate monocultures of low nutrition plants
- -ability to run tightly controlled experiments on pollination, on the effects of bees on plant physiology, on ecosystem dynamics, etc
- -fucking robot bees, my friend
- -hahaha think how confused those flowers must be
Also worth keeping in mind? People love, love, love framing science in condescending and silly sounding terms as an excuse to cut funding to vital programs. *Especially* if it’s also associated with something (gasp) ‘inappropriate’, like sex or ladyparts. This is why research for a lot of women’s issues, lgbtq+ issues, minorities’ issues, and vulnerable groups in general’s issues tends to lag so far behind the times. This is why some groups are pushing so hard to cut funding for climate change research these days.
Anything that’s acquired governmental funding has been through and intensely competitive, months-to-years long screening by EXPERTS IN THE FIELD who have a very good idea what research is likely to be most beneficial to that field and fill a needed gap.
Trust me. The paperwork haunts my nightmares.
So, we had a joke in my lab: “Nice work, college boy.” It was the phrase for any project that you could spend years and years working on and end up with results that could be summed up on a single, pretty slide with an apparently obvious graph. The phrase was taken from something a grower said at a talk my advisor gave as a graduate student: “So you proved that plants grow better when they’re watered? Nice work, college boy.”
But like, the thing is? There’s always more details than that. And a lot of times it’s important that somebody questions our assumptions.
A labmate of mine doing very similar research demonstrated that our assumptions about the effect of water stress on plant fitness have been wrong for years because *nobody had thought to separate out the different WAYS a plant can be water stressed.* (Continuously, in bursts, etc.). And it turns out these ways have *drastically different effects* with drastically different measures required for response to them to keep from losing lots of money and resources in agriculture.
Nice work, college boy. :p
Point the second: surprise! Anna Haldewang is an industrial design student. She developed this in her product design class. And, as far as I can tell, she has had no particular funding at all for this project, much less billions of dollars.
‘grats, Anna, you FUCKING ROCK.
ps: On a lighter note, summarizing research to make it sound stupid is both easy AND fun. Check out @lolmythesis – I HIGHLY RECOMMEND. :33
I’d also like to chime in that a chunk of my family are apple farmers, and one thing I learned visiting them is that you can’t always let bees pollinate. With certain apple varieties, people have to go out with little paintbrushes to pollinate them by hand, because if they cross-pollinate with the wrong variety the apples won’t come out the same. Beebots could potentially be a huge time-saver at that task, because depending on how the algorithms work, you could just tell them “Don’t go into the Gala field next door” and let them do the job more efficiently than you without having to worry about getting weird mutant apples.
Also holy shit all science is not interchangeable. Nobody got up one morning and said “instead of saving the bees I’m going to build a bee robot.”
The only problem with those robots is a marketing one. Make ‘em anthropomorphic, like pixies, and people would be all over that shit and want them as pets.
I feel morally obligated to remind everyone, when I see discourse like this, that there are vested interests in destroying the public’s faith in
- Evidence-based statements
- Publicly-funded science
- Critical examination of the media
- Affection and investment for the natural world
And this is something I’ve been explaining for years.
And next thing you know it’s 2017 and everyone is surprised that the CDC has been told not to use the words “vulnerable” or “evidence-based” when writing their budgets. And the people running the world are able to deny the effects of climate change while the waters rise. This is how you get hurricanes while people tell you there aren’t any hurricanes. And how conspiracy theories are more attractive than the truth.
We got here on purpose because we wanted to be here. Because cynicism seemed cooler than wonder. Because of course the world is broken so why bother?
Because we didn’t want to be like those wide-eyed nerds and their silly robot bees.
I think I may have rebligged the root post before without particularly examining how counter to my values it is. Though, I do truly hope that scientific research can fix the woes of ailing bees before we have to implement any robot army based solutions.
every time i see this im reminded of the “shrimp on a treadmill” thing that people were lambasted for being a “waste of taxpayer money”. DESPITE the fact that it was like a few thousand dollars MAX and done by a student in university (with a grant provided BY THE UNIVERSITY) to study how the negative water quality in the gulf of mexico caused by the bp spill would affect oxygen processing in shrimp.
which is a SIGNIFICANT part of the fishing industry down there and how some folks literally make their living. it also ties into ecology and conservation since you don’t want to overfish shrimp populations that arent going able to bounce back from it. you also dont want to start resorting to fishing methods that will do more harm to to the environment to try to get bigger hauls to hit basic demand if theres nothing there to catch.
my own research was mostly done out of pocket w a few hundred dollars grant despite the fact that it involved potentially an entirely new mode of sensory input as of yet undiscovered by science that had LOADS of potential applications in biology and robotics. but boil it down to “put a scorpion in a maze in the dark to see if it bumps into walls” on paper and people just kinda roll your eyes at you. hell, i even built my own lab apparatuses and paid for the materials with money from my food budget. (bulk dry spaghetti saved my life)
anytime you see a “lol this science was a waste of money” it’s almost always blatant propaganda to encourage the cutting back of research and the justification of budget cuts. dig a little deeper into “dumb studies” and there’s usually some very nifty applications or hypotheses being tested that have real world applications concerning problems that exist RIGHT NOW.
not to say you shouldnt think critically about WHY something is being studied, but the studies you usually have to look out for are the ones privately funded by groups looking to push an agenda (ones from christian “family” groups on homosexuality/lgbt issues, stuff from people with connections to big oil/etc who do studies on global warming, or on the other end of the political spectrum something from pro-marijuana lobbyist about how marijuana will cure -insertailmenthere-). there could still be good raw data in these studies, assuming it hasnt been altered or data sets excluded, but it will be presented in such a way to make their point so you have to keep that in mind (as well as their methodology and things that could have been intentionally or unintentionally skewing the data, but that goes for any study)
“anytime you see a “lol this science was a waste of money” it’s almost always blatant propaganda”
OP turns out to be a Russian propagandist
holy shit i didn’t even notice that lmao
Coming up with alternatives to augment natural processes is good sense.
We quite possibly “think” because of viruses.
Where can I vaccinate against this to become just the worst type of rube nincompoop
Visitors walking past the icy pond in the Japanese Hill-and-Pond Garden might notice that the painted turtles and red-eared sliders are not basking on the rocks as they do in summer. Where do they hunker down for winter? Turtles actually hibernate deep in the mud at the very bottom of the pond, insulated by layers of ice, water, and muck. When cold-blooded animals like turtles hibernate it’s called “brumation.” In winter, turtles no longer come to the water’s surface to breathe. Instead, they breathe underwater through specialized skin on their neck, legs, and tail. Baby painted turtles can even freeze solid for a few days and still survive! Though the turtles are hidden out of sight, you may be able to spot the koi even on the coldest days. They spend the winter in a similar, slowed-down state, sheltering in the warmer water under the ice.
