Terrifying Laser Bazooka Is Like a Handheld Death Star

Standard

In the right hands, broken electronics can be turned into something useful again. But useful isn’t the best way to describe Drake Anthony’s 200-watt laser bazooka made from a bunch of old DLP projectors he bought off eBay. Words like incredibly dangerous, do-not-try-this-at-home, or “are you crazy?” seem more appropriate.

For comparison, the handheld laser pointers used during PowerPoint presentations measure in at a measly 0.05-watts, while the FDA limits non-medical lasers to a maximum power rating of 0.5-watts. That means that Drake’s creation, which focuses four 50-watt lasers through a massive lens—is 400 times more powerful than what the FDA will let you play with. And those rules are there for a good reason. Lasers can be deadly!

In mere seconds this 200-watt laser bazooka can burn through the metal housing on a tower PC and would cause severe eye damage if used without wearing a welder’s helmet.

Why Female Praying Mantises Devour Their Partners During Sex

Standard

Female praying mantises have a habit of killing and eating their partners during sex, which sucks for the male. Or does it? A fascinating new study shows this sacrifice is actually giving the males a distinct reproductive advantage.

Sexual cannibalism among praying mantises is well documented, but scientists have debated the reasons for it. A new study published in Proceedings of the Royal Society B shows that females who eat their male partners after sex produce more eggs than those who don’t. What’s more, by eating the male, the widowed female ensures that her man is still providing for their offspring, even though he’s dead.

William Brown, a scientist at State University of New York at Fredonia and co-author of the new study, put it well: “Sexual cannibalism thus increases male investment in offspring.”

In praying mantises, around 25 percent of all sexual encounters result in the death of the male. The female typically begins by biting off her partner’s head, and she works down from there. Incredibly, this comprises about 63 percent of the female’s diet during the mating season. Scientists have speculated that it’s a way for the female to record a quick meal at a critical point in her reproductive life cycle, but this claim has largely remained unproven.

To see if this is actually the case, the researchers embedded traceable radioactive amino acids into crickets, which were subsequently fed to a population of male mantises. Each of these males was then paired with a female. Half of them were rescued from their two-faced lovers before cannibalism could take place, while the other half… well you know what happened to the other half. The researchers then set about the task of studying the reproductive success of each female involved.

By tracking the flow of radioactive proteins through the bodies of the females, the scientists could track the contribution of the recently-devoured male. Males who were devoured passed on nearly 90 percent of their tagged amino acids, while those who survived passed on about 25 percent—all of which were delivered via their ejaculate.

A significant portion of the amino acids were passed down to the baby mantises, which means they weren’t fully metabolized by the female. This means that, in addition to the male’s ejaculate, his body tissue is being used to produce eggs. The male—by virtue of his death—is providing nourishment to his offspring.

Those females who ate their partners produced more eggs than those who did not. On average, cannibalistic females produced about 88 eggs, whereas those who didn’t eat their partners produced about 37. That’s a big difference, one that gives cannibalized males a distinct reproductive advantage.

Well, at least in one-off situations. Males who survive mating encounters can potentially reproduce multiple times, which can also be seen as a reproductive advantage. Clearly, there’s an evolutionary tension here, one the scientists will have to look into a bit further.

Sexual cannibalism has also been observed in some spiders. But unlike these arachnids, whose reproductive organs become permanently damaged after sex, male mantises are able to copulate multiple times.

Magical Wheels Let This Car Roll in Any Direction

Standard

GIF

We’ve seen omnidirectional wheels installed on forklifts that have to deftly maneuver around crowded warehouses, but William Liddiard has invented a set that allow his Toyota Echo to move in any direction, spin 360-degrees, and slide into a parking spot making parallel parking easier than actual driving.

William calls his creation Liddiard Wheels—appropriately enough—and they’re powered by 24,000 pounds of torque applied directly to the wheels which gives them incredible precision. They can also be bolted onto any vehicle making it easy to upgrade your existing ride, and they’re designed can be used on roads in any weather condition.

If you rolled up to your drivers license road test with a set of these on your vehicle, do you think they’d accuse you of cheating?

What Is Music and Why Is It So Special?

What Is Music and Why Is It So Special?

Radiolab’s Jad Abumrad sits down to talk about music—its purpose, its function, its meaning—with filmmaker Mac Premo in this wildly frenetic video and somehow manages to explain why music is so special. Abumrad says that unlike words, which are basically just a code or an agreement between people, music just is what it is, and the response we have is innate. Music can magically get around a person’s rational defenses and is something that makes us who we are.

It’s a really fun video to watch, especially if you like music like Abumrad does.

69-Year-Old Surfer Hippie Has Life All Figured Out, Quit His Job As A Cop To Travel, Surf, And Sell Oysters

Standard

Bruce Gold is amongst the last of a dying breed. In his 20’s Bruce was a policeman, but he reached a crossroads at which he knew that life wasn’t for him, and he needed to strike out on the open road. So he quit his job and moved to world famous Jeffreys Bay in South Africa, one of the top surfing destinations in the world.

Instead of working that 9-to-5 grind like most of us he decided the best way to provide for life’s essentials was to gather oysters in Jeffreys Bay and sell them in the local pubs, and to the traveling surfers (Btw, 9-to-5 actually seems great, I’m usually working the 8-to-7 grind in order to bring you bros the best content every day here on BroBible).

At 69-years-old Bruce Gold is still living the dream, and I kind of wish I’d have never learned about his life but here we are, and now I’m thinking about what it’d take for me to unplug and follow that life right there.

Facts:

1) I love surfing.
2) I love being in, on, or near the water more than anything.
3) Oysters are my favorite food.
4) I’ve been a travelin’ fool ever since my parents took my on my first abroad trip when I was barely a preteen.
5) This man is living my dream.
6) The only reason I have to not drop it all and follow in this bro’s footsteps are, well, my entire life.

I’m always envious when I read stories about people like Bruce, and I figured this was a great story to share with you bros on an otherwise insignificant Tuesday.

These Are People’s Top 10 Sex Fears, And Unsurprisingly One Of Them Is F’d Up Body Hair

Standard

Let’s be honest here, bros, when you’re getting naked with some chick for the first time in anticipation of bumping uglies there can be some trepidation, fear of the unknown. Does she have an Amazonian jungle going on down there? Should I be worried about STI/Ds? What happens if the condom breaks? Do I even need a condom? Is this going to suck or be awesome?

Well, our colleagues over at UPROXX.com uncovered this recent study about what the average person’s top 10 biggest sex fears are, this way when you read through the list you can know that you’re not alone in your fear of things that go bump in the night:

I guess we’re all worried where our partners have been, and that’s probably a good thing because it’d go against human nature to dive dong-first into a big ol’ pile of crabs. It’s healthy to be cautious, and we’re not alone in our fears of STIs.

Watch A Yo-Yo Without A String Attached Defy Physics (And Then Learn The Actual Physics Behind It)

Standard

Veritasium is far and away my favorite YouTube channel on the entire internet. Derek Muller’s videos take some of the most complicated science … stuff (see how educated I am) and make it possible for even the most rock headed Bros to comprehend.

And he blows your mind in the process (like this video on the Magnus Effect).

In his most recent effort, he met with world famous yo-yoer Ben Conde, to show how he could use a yo-yo that didn’t have a string tied to it.

How does it manage to defy physics like that? Well, the answer is actually physics.

Damn, physics. You a woman of many talents.

The 2017 Porsche Panamera Turbo’s Wing Is Some Fucking Iron Man Shit

Standard

GIF

(Image: Porsche)

Today the world was introduced to the first major redesign of the Porsche Panamera. Nice smooth lines front to back, with a retractable spoiler like a freaking badass robotic razor blade.

Porsche’s official description of the device as per the new car’s press release is, surprisingly reserved:

On the Panamera Turbo, the wing also splits as it extends, providing additional surface area.

You don’t say.

The basic execution and one-two stage foldout pretty much looks the same as the old Panamera but, somehow, better. In fact I never even noticed the original Panamera’s spoiler deployment but this one has me like, whoa.

Maybe it’s the apparently slightly sharper edge. Maybe it’s just the great lighting in that promotional video. But it might be my favorite design feature on an altogether beautiful new car.

10 Signs Telling You Should Let Go Of What You Have And Move On

Standard

let go

The idea of letting go can seem terrifying. Strong emotional bonds and feelings can make it hard for us to move on – even when we know we are putting our happiness at stake.

However, it is important to embrace letting go and moving on. Holding on to old feelings and reliving past decisions can cause you to become stressed, upset and bitter. This can negatively affect your present and future, but you can make the conscious decision to let go so that you can live a peaceful and happy life.

Here are 12 moments that are telling you to let go and move on.

1. You’re Changing Into Someone You’re Not

Our personal values and goals and dreams define who we are as people. If you think that these things are changing for the worse, it may be that your job/partner/friend/family are trying to make you be someone you’re not. If this happens, it is time to move on – you will never be happy pretending to be someone else.

2. Your Dreams Are Getting Harder To Achieve

Your dream once seemed achievable, but now you think that it would be impossible to achieve them – or that it would be a waste of your time. If you feel this way, it means you need to take action by putting your dreams first again.

3. You’re Faking Happiness

If you feel like you have to fake a smile every day, it may be because you feel like you need to hide your true self. Let go of anything that makes you feel this way, as it clearly brings you down and lowers the quality of your life.

4. You Are Exhausted

You feel tired every day, partially because your work or the people in your life are draining your energy. If you can relate to this, find the thing that is draining your energy so you can cut it out of your life and move on.

5. You Feel Isolated

If you constantly feel misunderstood and alone, it is probably time to surround yourself with a new group of people. If people value you, they will try to make you feel important and they will accept you for who you are.

6. You Feel Bored

When you wake up you don’t feel excited for the day ahead. You mostly feel bored and resentful, as you think the day won’t go well.

7. You Don’t Feel Appreciated

You feel like you’re being taken for granted, as people expect things from you but they don’t thank you or congratulate you. If you have people in your life who don’t respect you, cut them out of your life so that you can find friends who will treat you well.

8. You Are Constantly Making Sacrifices

People always expect you to give up your time, energy and money, but they don’t return the favor. You experience all of the pain and anxiety, but the other person is unwilling to do the same.

9. You Make Excuses For Others

You justify the behaviour of others because you are scared of letting go and moving on. You say things like;

“He wasn’t being insensitive; he just had a tough day.”

“She has a short temper and I’m more relaxed, so I don’t mind dealing with her temper.”

10. You Repeatedly “Try To Make It Work” Even Though You Should Let Go

You tried over and over again to make the situation more bearable for you, but with little to no success. It is time to let go and move on.
