Rodent research is a horrible testing method. This video explains it well: https://www.youtube.com/watch?v=FHl0nIdbiLA

that's basically a condescending mansplain

If you only watched the video, you'd know, there is also a reputable scientist teaching both of the actors.

Would you like to know whether that scientist is male or female? Does it matter? Go see the video.

You might find being vegetarian easier than you think. It's a little more effort while you learn new recipes, and depending on where you live you'll have less choice when you dine out, but I have been (mostly) vegetarian for the last two years and found it surprisingly easy. :)

Some experience for me. Unfortunately, after a couple of years, it was also easy to relapse when my social circles changed.

Don't consider it a relapse. Meat is not a drug. You can leave it as many time as you want. It's a journey you might have to take rest.

Are men not allowed to teach? Adam Ruins Everything is an educational show - they’re all actors

the man depicted in the animation is explaining only to women the actors behind the cartoon are reading a script written by someone...are you fooled by the puppetry ?

> is an alt-right meme and shout-out to Milo Yiannopoulos Wait, since when? The way it is phrased, and often the discussion it prompts, is certainly transphobic/homophobic, but any context I've seen it in (which hasn't been for a good few years) has been totally divorced from the alt-right. Did I miss it getting picked up by those groups at some point?

http://knowyourmeme.com/memes/traps “Are Traps Gay?” is a satirical debate within otaku and alt-right online communities, attempting to determine if being attracted to a crossdressing man is an indication of homosexuality. This debate is often discussed alongside the discussions of anime and futanari character design. On February 21st, 2015, Redditor NyaaFlame posted a thread entitled “Why Liking Traps Isn’t Gay” to…

Because household dogs don’t retain that behavior in the same way cats do.

Yep. My dog will chase things, but he wouldn't know what to do with a prey animal if he caught one. He's good at attacking the food bowl, and that's about it.

This kind of reminds me of my dog. He was quite happy with chasing birds whenever they landed in the garden. One day he caught one and killed it.

Then he kinda ignored the corpse for about week because he didn't know what to do with it and then we removed it from the garden (since we found it by then)

The bird was probably sick anyway since my dog is one of the worst hunting dogs I've seen.

I'm pretty sure it's due to the domestic upbringing, if he had grown up on a farm and actually had to hunt small rodents then he'd probably know how to eat them.

So rats have a built in gene sequencer and detect the base pairs directly?

Probably not, but why is that so far fetched? They'd just need to be dissolving it with chemicals, backed up by a neural network to identify the sequence (rat's brain, anyone?). That's kind of how smell works in general to begin with. As for why rats may develop the ability to sequence XX vs XY - if rats with the ability to do so were killed far less than those without, then rats would quickly evolve the ability to d…

Or there could be a signaling molecule specific to sex that directly interacts with some receptive system in the animal. Maybe it's nose? DNA sequencing would be an awfully slow signal given the technology available to the organism...

Your friend's eye color is defined by some genes. You don't need a gene sequencer to see what they are.

To see the color you mean?

Yes, it's terrible. Make sure none of the following list apply to you or anyone you care for. >If you’ve ever taken antibiotics, had a vaccine, a blood transfusion, dialysis, an organ transplant, chemotherapy, bypass surgery or joint replacement, you have benefited from animal testing and research. In fact, practically every drug, treatment, medical device, diagnostic tool or cure we have today was developed with the…

I don't buy the argument/implication that it's somehow hypocritical to oppose something while actively benefiting from it, as long as one is upfront about that fact.

For example, say that we have genuinely useful medical information as a result of Unit 731 experiments and similar crimes (which may or may not be the case; I have no idea). There's no contradiction if one person supports using those existing results to save lives while simultaneously opposing further collection of such results.

Another example: I personally eat a lot of meat (keto/LCHF), but even so I might support legislation to ban killing animals for food or sport, because the personal sacrifice would only be worth it to me if it came attached to a systemic change.

This reminds me of Feynman's story of the researcher who eliminated possible variables in rat experiments one by one, to find a surprising result (EDIT: To find that rats didn't need smell, spatial relationships, taste, or vision to find the cheese - the sound of the floor was enough) https://www.realclearscience.com/blog/2014/02/the_rat_experi...

I suppose humans tend to underuse, or undertrain, their senses, so we fail to consider the possibility that other animals might be taking advantage of their senses in different ways. In elementary school, I used to listen to the sounds of people’s pencils scratching on the desk, and could accurately determine what they were writing, especially if my head was near the desk and I knew what their handwriting looked like…

I believe you. Have you considered the possibility that it wasn't your ears?

It's interesting to think about what this could mean for people. We use these mice because they often are convenient models for humans. Are our moods are just as affected by combinations of lots of little things like these - smells, hormones, chemicals in the cleaners, hair products etc. On the scary side imagine being able to use this for evil. Spray something like this on your product to manipulate people's hormona…
