Octopuses sometimes punch the fish they go hunting with, just cuz they feel like it

Have you ever been part of a group project and had the overwhelming urge to punch one of your partners?

Of course you have. We all have. Even those of us who aren't prone to violence can understand the urge. In fact, we're all engaged a big group project right now called The Coronavirus Pandemic, and there are whole lot of people in the U.S. group who are just begging for a smackdown. Still think the virus is a "hoax"? Thwap. Wearing your mask as a chin diaper instead of covering your mouth and nose? Whpsh. Toting your AR-15 to the state capitol to threaten public officials because they insist on trying to protect public health? TKO time.

Apparently, those of us who are feeling a bit punchy these days are in good company. A new study has found that octopuses occasionally punch fish that they cooperatively hunt with, seemingly just because they feel like it. Though it's not clear exactly why they do it, scientists say it doesn't appear to be an act of aggression. Some think that they might do it out of "spite" or to influence better hunting behavior.

In other words, Mr. Octopus is hunting along with some annoying group of fish until he's finally like, "Dude, you're bugging the crap out of me. Stop it." Thwack. Or "Dude, you're fudging everything up. Knock it off." Thwack.

Some scientists also think octopuses will throw a punch in a self-serving, I'm-taking-that-just-because-I-can of way. "Dude, back the hell up. That prey is mine." Thwack.

If we want to get a bit more scientific about it, octopuses are known to hunt collaboratively with fish so that they can cover more area and increase their chances of catching something. In a new report published in Ecology, scientists describe how one kind of octopus in particular, the big blue octopus (also known as day octopus), seems to express displeasure with their hunting partners by randomly lashing out, using "a swift, explosive motion with one arm." Or in other words, punching.

That's the word the scientists actually use. Punching. Yay, science.

It seems that the humor is just inherent in the visuals. Eduardo Sampaio, one of the study authors and a Ph.D. student at the University of Lisbon, found it hilarious when he first observed the behavior from the cephalopods he was studying. "I laughed out loud, and almost choked on my own regulator," he told Live Science in an email.

It might seem like the most logical explanation is that the octopus is simply knocking the fish away from the prey it wants. Sampaio explained that that is what some scenarios indicate.

"Despite collaborating, each partner will always try to maximize its benefits," he told Live Science. "In the cases where prey is readily available, the octopus seems to use 'punching' as a way to control the partner's behavior in a self-serving way."

However, the researchers also observed that there were instances where there didn't seem to be any benefit to the octopus to punch the fish. More research is needed to figure out what that's all about, but that's where the "spite" speculation comes in.

It is quite something to witness—the octopus and fish swimming along nicely together when all of a sudden one of those tentacled arms flies out and punches a fish out of nowhere. It's also fun to speculate whether the octopus is just being a big old bully or if that fish actually deserved it.

We can come up with whole storylines for why Mr. Octopus feels justified in sucker-punching his partner. Maybe the octopus is in a bad mood and the fish is just in the wrong place at the wrong time. Or maybe the little guy is just super needy and hovering, and it's the octopus's way of saying, "Back off. Just because we work together doesn't mean we're gonna be friends."

Octopuses are, after all, one of the most intelligent animals on earth. My guess is if they're punching the creatures they're working with, they probably have a good reason for it.

4 simple hacks to help you meet your healthy eating goals

Trying to eat healthier? Try these 4 totally doable tricks.

Most of us want to eat healthier but need some help to make it happen.

True

When it comes to choosing what to eat, we live in a uniquely challenging era. Never before have humans known more about nutrition and how to eat for optimal health, and yet we’ve never been more surrounded by distractions and temptations that derail us from making healthy choices.

Some people might be able to decide “I’m going to eat healthier!” and do so without any problem, but those folks are unicorns. Most of us know what we should do, but need a little help making it happen—like some simple hacks, tips and tricks for avoiding pitfalls on the road to healthier eating.

While recognizing that what works for one person may not work for another, here are some helpful habits and approaches that might help you move closer to your healthy eating goals.

Goal: Snack on less junk food

Tip: Focus your willpower on the grocery store, not your home

Willpower is a limited commodity for most of us, and it is no match for a bag of potato chips sitting on top of the fridge. It’s just a fact. Channeling your willpower at the grocery store can save you from having to fight that battle at home. If you don’t bring chips into your house in the first place, you’ll find it a lot easier to reach for something healthier.

The key to successful shopping trips is to always go to the store with a specific list and a full stomach—you’ll feel much less tempted to buy the junky snack foods if you’re already satiated. Also, finding healthier alternatives that will still satisfy your cravings for salty or crunchy, or fatty foods helps. Sugar snap peas have a surprisingly satisfying crunch, apples and nut butter hit that sweet-and-salty craving, etc.

Goal: Eat less sugar

Tip: Instead of “deprive,” think “delay” or “decrease and delight”

Sugar is a tricky one. Some people find it easier to cut out added sugars altogether, but that can create an all-or-nothing mindset that all too often results in “all.” Eating more whole foods and less processed foods can help us cut out a lot of ancillary sugar, but we still live in a world with birthday cakes and dessert courses.

One approach to dessert temptation is to delay instead of deprive. Tell yourself you can have any sweet you want…tomorrow. This mental trick flips the “I’ll just indulge today and start eating healthier tomorrow” idea on its head. It’s a lot easier to resist something you know you can have tomorrow than to say no to something you think you’ll never get to have again.

Another approach when you really want to enjoy a dessert at that moment is to decrease the amount and really truly savor it. Eat each bite slowly, delighting in the full taste and satisfaction of it. As soon as that delight starts to diminish, even a little, stop eating. You’ve gotten what you wanted out of it. You don’t have to finish it. (After all, you can always have more tomorrow!)

Goal: Eat healthier meals

Tip: Focus on fresh foods and plan meals ahead of time

Meal planning is easier than ever before. The internet is filled with countless tools—everything from recipes to shopping lists to meal planning apps—and it’s as awesome as it is overwhelming.

Planning ahead takes the guesswork and decision fatigue out of cooking, preventing the inevitable “Let’s just order a pizza.” You can have a repeating 3-week or 4-week menu of your favorite meals so you never have to think about what you’re going to eat, or you can meal plan once a week to try new recipes and keep things fresh.

It might help to designate one day a week to “shop and chop”—getting and prepping the ingredients for the week’s meals so they’re ready to go in your fridge or freezer.

Goal: Eat more organic/humanely raised food

Tip: Utilize the “dirty dozen” and “clean 15” lists to prioritize

Many people choose organic because they want to avoid pesticides and other potentially harmful chemicals. Organic food is also better for the planet, and according to the Mayo Clinic, studies have shown that organic produce is higher in certain nutrients.

Most people don’t buy everything organic, but there are some foods that should take priority over others. Each year, researchers from the Environmental Working Group (EWG) analyze thousands of samples of dozens of fruits and vegetables. From this data, they create a list of the “Dirty Dozen” and “Clean 15” fruits and vegetables, indicating what produce has the most and least pesticide residue. These lists give people a good place to start focusing their transition to more organic foods.

To make organic eating even simpler, you can shop O Organics® at your local Albertsons or Safeway stores. The O Organics brand offers a wide range of affordable USDA-certified organic products in every aisle. If you’re focusing on fresh foods, O Organics produce is always grown without synthetic pesticides, is farmed to conserve biodiversity, and is always non-GMO. All animal-based O Organics products are certified humane as well. Even switching part of your grocery list to organic can make a positive impact on the planet and the people you feed.

Healthy eating habits don’t have to be all or nothing, and they don’t have to be complicated. A few simple mindset changes at home and habit changes at the grocery store can make a big difference.

3,700-year-old Babylonian stone tablet gets translated, changes history

They were doing trigonometry 1500 years before the Greeks.

Dr. Daniel Mansfield and his team at the University of New South Wales in Australia have just made an incredible discovery. While studying a 3,700-year-old tablet from the ancient civilization of Babylon, they found evidence that the Babylonians were doing something astounding: trigonometry!

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.
