Why Do Planes Takeoff at Such a Steep Angle?

Planes are feats of modern engineering and we are so thankful they exist. But why the heck do they have to have such a steep takeoff?

The answer, as you might have guessed, is for practical reasons. Planes are at their most efficient when they are at their cruising altitudes, so pilots do their best to take off, ascend sharply to around 35,000 feet, and cruise until it’s time to make that final descent.

Because the airlines and pilots have to keep customer comfort and other plane traffic in mind, the pilots can’t take off as steeply as they’d like to, but obviously, that ain’t gonna…fly…

Goats Are Drawn to Happy People, According to Research

Good news, goat lovers. If goats are drawn to you, that means you are a happy person. That’s an obviously self-fulfilling statement, but it also may be scientifically true that goats prefer you because you’re happy.

At least that’s what a recent study says.

The study says that goats prefer “positive human emotional facial expressions.” In other words, if you’re smiling, goats are more drawn to you. In the study, goats roamed and explored an area that had two black and white photos at goat-eye level. One was of a smiling human face, the other an angry face.

The goats preferred to approach the smiling face. This suggests that goats have the ability to read human facial expressions. Companion animals such as dogs are recognized as able to read human emotions, but this is the first research to show that goats might have that same ability. So get out into the country today and go smile at some of these adorable fluffers!

These 5 Puzzles Will Warm Up Your Brain

Your brain could always use a good workout, and these five puzzles are just the thing to do the trick. Enjoy!

#5. A kingdom far, far, away.

Far, far, away lived a king who didn’t allow anyone in or out of his kingdom. There was a single bridge that connected them to the outside world, and royal orders stated that anyone moving outside should be killed, and anyone coming in should be turned back.

There’s a single guard on the bridge and he’s allowed to take rest breaks inside a hut of no more than 5 minutes. It takes 8 minutes to cross the bridge.

Even so, one woman manages to escape the kingdom. How?

There’s a Scientific Reason Why Food Tastes Bad After Brushing Your Teeth

As anyone who has ever brushed their teeth knows (and, hopefully, that’s everyone) you don’t want to eat something too soon after brushing. There are horror stories of foolish souls who thought it would be a good idea to down a glass of OJ within minutes of hitting their teeth with some Crest. They were never heard from again.

But why does toothpaste have the capacity to ruin your breakfast? Science, of course, has the answer.

Photo Credit: Pixabay

It has to do with sodium laureth sulfate – also known as sodium lauryl ether sulfate (SLES) and sodium lauryl sulfate (SLS). The chemicals are the wetting agents in your toothpaste (meaning they lower the surface tension of a liquid) and work to create the foam that makes the paste easier to spread across your teeth.

Fun fact: They’re also used in detergents, fabric softeners, paints, laxatives, surfboard waxes, and insecticides. So, you know, if you eat any of those things, watch your breakfast choices as well.

Both SLES and SLS screw with our taste buds abilities in 2 ways. First, they suppress the receptors that perceive sweetness (hence why my grape juice tasted sour), and second, they break up the phospholipids on our tongue. Those are fatty molecules that inhibit our receptors for bitterness – so when SLEs and SLS are coating our tongues, bitter tastes are enhanced.

The bottom line is that anything you eat or drink after lapping up the chemicals in your toothpaste is going to taste less sweet and more bitter than it normally does. If the phenomenon really bothers you, there are toothpastes out there that are SLES/SLS free – you won’t have your usual foamy experience, but you can also pick your breakfast juice without worry.

Worth it? I mean…

Women Are More Resilient Than Men, According to Science

Women are pretty darn strong. Need I remind you that many spend months of their lives enduring pregnancy and hours of labor all to push something the size of a watermelon out of their vaginas? Think men can do that?

Photo Credit: AMC

Although the recent research defines men as people with an XY chromosome makeup and women as ones with XX’s – meaning it applies to cis individuals and not people who identify as different from their chromosomal makeup – it’s still pretty damning when it comes to which of the sexes is more likely to survive through tough situations. James Vaupel and his team at the University of Southern Denmark in Odense concluded that in fact women are statistically more likely to survive in times of crises (I mean, we saw this on The Walking Dead, so good luck with the zombies, dudes!) like famines, epidemics, and enslavement. The conclusions were drawn by measuring things like population and life expectancy, and it boils down to the fact that women are survivors.

Virginia Zarulli, from the University of Southern Denmark’s Institute of Public Health explained to Global Citizen that females are simply born with a different sort of advantage:

“In simple words, it is easy to see that if by chance a bad mutation takes place on the X chromosome, women have another X that can partly – or totally – compensate for it, while men don’t have that possibility.”

Not only that, but as a report in The Guardian points out, bodies that produce estrogen have more of a guard against disease. Producing testosterone increases the risk of fatal infections, not to mention that high levels of testosterone leads to more risky and life threatening behavior.

The advantage begins at birth – male infants have higher mortality rates than their female counterparts – and continues through the end of life, as the life expectancy for women globally is four years longer than that of men.

Don’t feel bad, guys – you’re still really good at plenty of things. When it comes to digging into life by the fingernails and not letting go until God him- (her-?)self rips you loose, though, women take the cake from cradle to grave.

So make friends with the women in your life, maybe consider it part of your preparation for the zombie apocalypse. I mean. It can’t hurt.

This Is Why You Shouldn’t Wash Your Clothes in Warm Water

The majority of people think that washing clothes in warm water is always better. The heat kills the germs, right?

While that may be true when you’re washing your hands (or other body parts), it turns out the logic doesn’t hold true for getting the grime, stink, and stains out of your dirty clothes. Back in the day, hot water was required to get the most out of your detergent, but now most manufacturers have created products that work as well in cold water (unless you’re using powder, which will require warm water to dissolve).

And get this: it’s not only true that warm water doesn’t get your laundry any cleaner than cold, but there are several reasons that washing in cold water is actually the better way to go.

Better Stain Removal

Some types of stains – like ones from blood, sweat, and other proteins – will only come out in cold water. Warm water will set them in further, and when it comes to keeping your colors bright and your fabrics the right size, cold water is also your friend.

It’s Environmentally Friendly

90% of the energy used to power your washing machine is used to heat water, so using exclusively cold water saves hundreds of pounds of carbon dioxide emissions every year.

Wallet Friendly

Switching to cold water could save your family more than $200/year, according to personal finance blog The Simple Dollar.

So, while you might be tempted to set the water to hot if you’ve got something particularly gross or smelly, just resist! Your clothes, bank account, and the environment will thank you!

Science Proves the HPV Vaccine Doesn’t Actually Lead to More Sex Among Teens

No matter how many concerned parents have warned that sex education will lead to teens having more sex, science always says otherwise. The same is true for access to birth control. And, according to the latest study (which confirms results from a similar study done in 2015), promoting the HPV vaccine to this generation, you guessed it, doesn’t lead to more sex.

HPV, one of the most common sexually transmitted diseases in the United States, has been strongly linked to a number of cancers, including those attacking the cervix, vulva, vagina, penis, and anus, along with some forms of oral cancer.

Even though the vaccine has been found to prevent some forms of the virus and the following cancer – and is recommended by the CDC – fewer than half of girls (and even fewer boys) currently receive the full series of shots. This is due to prevailing (inaccurate) distrust of vaccines, but also a worry among some people that preventing an STD could lead to riskier sexual behavior among teenagers.

The most recent study, which compared teens in states with HPV vaccination promotion to teens in states without promotions, was recently published in the scientific journal Pediatrics. It compared the two lists of teenagers to the results of a multi-year survey of risky teen behavior, and found no difference in teens’ decisions and behavior based on the state they reside in.

Basically, kids are going to engage in sex – risky and otherwise – regardless of whether we protect them against cancer.

“Concern that legislation will increase risky adolescent sexual behaviors should not be used when deciding to pass HPV legislation,” concluded the study.

Currently 23 states and Washington D.C. have passed legislation related to the promotion of the HPV vaccine. The specifics vary from in-school awareness campaigns to programs that require insurance companies to cover the cost of the shots.

The study’s primary author, Erin Cook, told PBS that “the big takeaway is that the passage of legislation regarding HPV didn’t seem to be associated with any changes in adolescent sexual behaviors in the sample of states we were able to look at.”

Worry not, parents. You can protect your child from all sorts of cancer while being assured that the shots won’t cause them to engage in any promiscuous behaviors.

At least, no more than usual.
