Back to the Future: Scientists create a real hoverboard

Ever since Marty McFly hopped aboard his pink hoverboard in 1989's Back to the Future Part II, the world has been waiting for real scientists and engineers to catch up. Now, finally, it appears that you can get your hands on one - if you have $10,000.


Ever since the fictional hoverboards in 1989’s Back to the Future Park II children (and adults) have dreamed of scooting along six inches from the ground, safe from the rough terrain and water which would stop a normal skateboard in its tracks.

In the 90s the film’s director Robert Zemeckis cruelly spread rumours that a commercial version was under development, raising hopes around the world before scientists dashed them with a dose of reality - the problem was just too hard.

But now a Californian startup claims to have cracked it and developed a working prototype, although there are several catches: the battery only lasts seven minutes, it will only float over smooth metal and it costs $10,000. There is also a limited supply of just ten hoverboards available.

Hendo Hover has turned to Kickstarter to crowdfund the $250,000 it needs to create the first run of products. It claims to need the money to put the “finishing touches” to its device.

Currently its HENDO hoverboard levitates one inch from the ground but will only work above conductive surfaces.

The money raised will also go towards “creating places to ride them”, as existing skateparks with their tarmac surface are unsuitable. Engineers claim that one day they could be improved to work on any surface, but this is still some way off.

Those pledging $5 will get a mention on the company’s social media accounts, while those giving $100 will get a five minute ride on a hoverboard. Only those giving $10,000 will get a hoverboard, and there are only 10 available in this campaign.

The company claims that those donating to get a hoverboard will be presented with the devices today, but only $3,856 of the target of $250,000 has so far been raised, meaning that nobody with deep pockets has yet taken the plunge.

“Our engineering team has been amazing, rapidly iterating on design after design. In fact, this our 18th prototype, and we continue to make advances week after week,” says the company’s Kickstarter campaign.

“The magic behind the hoverboard lies in its four disc-shaped hover engines. These create a special magnetic field which literally pushes against itself, generating the lift which levitates our board off the ground.”

A video reportedly showing the device in action gives the impression that it’s rather hard to control: without wheels or friction it seems nearly impossible to point it in a specific direction. It is intended to be propelled with the push of a foot, like a skateboard, but its creators say that the technology used to make it levitate could be adapted to provide forward momentum.

Despite the obvious connection to the Back to the Future franchise featuring Michael J. Fox as Marty McFly, it seems that the company is making no direct connection: “Yep, there was a movie. However, our attorneys have told us not to go there.”

The company has also created a “whitebox” device which will float in the same way as the hoverboard, and be used to demonstrate the technology to engineers: “It is designed to be explored, taken apart, and analysed, encouraging you to dare to wonder.”

The startup hopes that it can licence the technology to be used in factories, warehouses and anywhere else that levitating heavy objects could prove useful. Telegraph.co.uk

6 Bullshit Facts About Psychology That Everyone Believes


Psychology is one of those subjects that everybody likes to think they know something about. We love to go around diagnosing our friends and co-workers, both to make sense of the world and to make ourselves feel like we're smarter than they are.

But like any science that makes its way into the pop culture, a lot of the "common sense" statements we hear every day are so wrong that they border on raving idiocy. Such as...

#6. "If You Let Your Anger Out, You'll Feel Better!"



You always hear people talk about how "cathartic" an experience was and how much better they feel, or you'll hear them say things like, "If you keep your anger bottled up, one day you'll just snap!"

In fact the "about to go crazy because he can't express anger" character is a mainstay in television and movies (see that Simpsons episode where Ned Flanders finally loses it, and every movie where a renegade cop fires his gun into the air instead of unloading on the bad guy who just killed his wife).

Things like squeezing stress dolls, screaming into a pillow, hitting a punching bag and strangling a kitten are all practices that we've seen offered as healthy alternatives to walking up to the fish counter at Farm Fresh and drowning the clerk in the lobster tank.


A lot of actual therapies have been constructed around this idea, and they all basically encourage you to curb your anger by feeding a knuckle sandwich to a punching bag, to prevent you from doing the same to your boss. It makes sense, right? Why throw your wife against the refrigerator when the casserole she under-cooked will shatter to pieces in a much more literal, and satisfying way?

Why it is Bullshit:


Research says it doesn't work. Expressing your anger, even against inanimate objects, doesn't make you less angry at all. In fact, it actually makes you want to get pissed off. Imagine if Bruce Banner walked around all day looking for an excuse to hulk-out, but replace the embarrassing shredded pants with friends and loved ones who are legitimately terrified every time his favorite sports team loses.

See, we humans have these things called "habits." When we do something, and it makes us feel good, we want to do it again... and more often. This is why you don't see a lot of Buddhist monks throwing bricks through storefront windows on their path to enlightenment and Lifetime original movies spend more on broken casserole dishes than on acting. The rush of anger is addictive as hell, and letting yourself lash out as a means to control your anger is like drinking to control your urge to drink.

 And that's bad news, considering there are lots of situations where you don't have an inanimate object to take it out on. If a person gets entrenched in the habit of beating the living shit out of an inanimate object every time they get upset, heads are going to roll if they can't excuse themselves from a meeting to go chokeslam the tank on the break room water cooler.



#5. "Just Believe in Yourself, and You'll Succeed!"



The "self-esteem" thing has been hammered into our brains for decades, based on the belief that high self-esteem types achieve more in school, make and keep more friends and, in general, function better as a member of society.

Pretty much every single high school movie is a huge proponent of this theory. The fat, dumpy pariah, tired of years of depressing abuse, digs deep down and discovers his/her own self-worth in time for the big dance/game/senior trip. Then the entire student body takes notice of this radical change and raises this loser up to the most popular kid in school (roll credits to a Green Day song).



Numerous training programs and self-help books take this idea and run with it; promising that building self-esteem is the key to overcoming obstacles and failure. Even elementary schools jumped on board and started giving self-esteem classes to kids, because as all Americans know, the key to happiness is constant rewards for little to no actual accomplishments.

Why it is Bullshit:

This seems to be one of those deals where they've confused correlation and causation. Rather than thinking, "Maybe kids with high self-esteem feel good about themselves because they get good grades in school and have lots of friends," they decided that it's the other way around, that they succeed because they have self-esteem. So they tried to teach people to feel good about themselves for no other reason than pure entitlement, figuring the actual reasons for feeling good about themselves would follow at some later date.

This results in some kids having too much self-esteem, a breed of human that scientists classify as "douchebag." [See Figure 1.1]


We're not kidding. Research shows kids who have an inflated sense of self-worth become aggressive when their sense of superiority is called into question, leading to a more damaging fall for little Billy when he realizes what a loser he is (whereas fat Ralph already knew himself to be a loser and is therefore immune to disappointment).

We're certainly not experts, but it would, you know, seem like the solution would be to teach the stuff that leads to success (like social and communication skills, better strategies at dealing with stress, etc.) and just let that lead naturally to success and thus self-esteem, rather than just bypassing all that and going right for the self-esteem part.

Mr. Miyagi didn't teach the Karate Kid to believe in himself. He taught him how to kick people in the fucking head.

#4. "Cult Members are Stupid, Gullible Sheep!"



Quick, go find an Internet article that mentions Scientology. Now check out the comments.



You will find almost universal agreement that anyone who participates in a cult (or, organized religion of any kind) is either weak, retarded or some kind of weaktarded combination of the two. We tend to associate cults with fanaticism, assuming that they are all made up of people that wear bed sheets and live in backwoods communes pissing in Dixie cups. Thanks to high profile, apocalyptic and/or suicide cults like the Branch Davidians and Heaven's Gate, we don't have much reason to think otherwise.

Why it is Bullshit:

Studies show cult members are just as intelligent, if not more so, than the general public. And around 95 percent of cult members are perfectly sane (when they join up, anyway), with no history at all of real psychological problems. They're not stupid, and they're not crazy.

Of course this only serves to make cults even scarier. How in the hell do these groups get people--who are every bit as sane and smart as your best friend--to join up?

OK, ask yourself this: Why do rebellious biker types all immediately go out and start dressing and talking exactly like other biker types?





Why did you do, well, every single thing you did in your teenage years?



As social animals we are hard-wired to want to belong to a group. It's a need as basic and real as hunger or sex. When we get cut off from our group--say we lose a job, or move to a new city, or break up with our girlfriend--we go a little crazy. Cults are very, very good at finding people in that exact moment of weakness, and saying exactly the right things. Those pamphlets that sound so corny and transparent to you, read like a glorious breath of fresh air to somebody caught in one of those rough spots.

So sure, when we're in our normal, stable state of affairs we like to imagine ourselves coolly shooting down all of the charismatic cult leader's stupid-ass claims with the power of pure critical thinking. But remember that the next time you're drunk dialing your ex-girlfriend in the middle of the night, or stalking her new boyfriend, sneaking into the parking lot where he works and pooping on the hood of his car.

If you can't remember ever doing something dumb and embarrassing because you were feeling lonely and rejected, well, either you're very young, or you were just too drunk at the time to retain the memory.

And once these people are in the cult they realize that, no, not all cult members wind up as part of some bizarre suicide ceremony. Most lead normal, successful lives.


And once they make friends with these normal, successful people, what are they going to do when they run into some smartass like the Internet commenters above, who talk about how only retarded sheeple believe that garbage? They stand up for the group, that's what.

It's not even about defending the beliefs at that point, it's about defending their friends. And mindlessly doing things because all our friends do them is pretty much 90 percent of what society is.






#3. "Be Careful! Advertisers Use Subliminal Messages to Make Us Do Things!"


This myth seems to re-emerge every decade or so in a different form. In the 80s it was "backward masking," supposed hidden (and Satanic!) messages in rock music, only audible when played backward, yet able to secretly influence the teenage brain when played normally.

But before that it was subliminal messaging, a technique whereby advertisers could allegedly flash a message on a screen so fast it wasn't consciously noticed, yet still able to trick your subconscious into doing or buying whatever the advertiser said.

Can you spot the subliminal ad in this episode of House?

These days you'll hear similar claims about "neuro-linguistic programming," which performers like magician Derren Brown claim allows them to control any subject by slipping certain command words into a sentence, unnoticed.

All of it amounts to the same thing: forms of communication that can magically bypass your conscious mind and manipulate your subconscious until you're nothing more than a helpless puppet.

Why it is Bullshit:

Not only do none of these particular methods work, as far as we know, no methods for subliminal messaging work. No, your brain can't pick up backward messages when played forward, and even when you intentionally play a track backwards, most of what you think you hear is a product of your own imagination.

The one study that claimed subliminal "flash frame" advertising worked (saying that rapidly flashing "Drink Coca-Cola" and "Hungry? Eat Popcorn" on a movie theater screen lead to massive increases in the sales of both products) is now believed to have been based on falsified data, if it ever actually happened at all.


Turns out people just like eating popcorn at the movies.

As for neuro-linguistic programming, well, there's a reason why the main guy known for using it is a magician.

But this is common sense. If there really was a reliable method for distributing invisible and unheard messages that could turn the masses into robots, whoever mastered it first would utterly rule the world.

They wouldn't need a military to invade another country, they'd just have to get their broadcast heard by the population there, and they would be helpless to resist. The fact that every single government in the history of the planet has failed to invent a method for this, no matter how badly they wanted it, makes us pretty comfortable in calling it bullshit.


#2. "We'll Find Out if He's Lying! Give Him a Lie Detector Test!"



What do murder suspects, government job applicants and game show contestants all have in common? They can all wind up hooked up to a polygraph to see if they're telling the truth.

Polygraph (commonly called "lie detector") tests go back to the early 20th century, and have been used in law enforcement since the 1920s. Over the next 80 years the machines became sufficiently advanced that society allowed their use in game shows.

Remember The Moment of Truth? Where they hooked contestants up to a polygraph so that they could get caught in outrageous lies and humiliate themselves in front of millions of people for money (which really just describes every game show, ever)?


Even Maury Povich uses polygraph tests to "help" a bafflingly large number of couples determine whether one of them is cheating. And while it seems odd for guilty people who believe in the tests to agree to be tested, Maury isn't exactly known for having Nobel Laureates or members of Star Fleet as guests.

Why it is Bullshit:

The problem was always the "lie detector" nickname given to the devices. It implied that the machines somehow know the truth, and can sense falsehood in the air. Obviously they don't (as that would be, you know, magic). They instead simply measure a number of physical responses that may mean you're lying.

Now, studies do show that polygraph tests are slightly better than, say, marshmallows at determining a person's truthfulness, but they are far from completely accurate. In 2003 a huge study by the National Academy of Sciences found polygraphs do help detect lies at a rate a little better than flipping a coin does. But that's actually a bad thing; if your hit rate is just higher than chance, the sheer number of false positives render the effort worthless. For instance, when using the machines to screen employees (as federal agencies do in the U.S.) they found you'd be better off just rejecting the guys who have "shifty eyes."


The problem is there are a huge number of variables that can throw off the results, everything from the personality and physical condition of the person taking the test, to the technique of the guy asking the questions, to the way the results are scored, to countless tricks people have figured out that can throw the test off (Soviet spy Aldrich Ames beat the polygraph... twice).

That's why it's in some ways worse than flipping a coin. With the coin, you know it's random. With the polygraph, you get a false sense of security (after all, the guilty guy who beats a test is now less of a suspect than if he hadn't been tested at all).

Damn, you'd expect more from a machine when one of its inventors also created Wonder Woman. Or maybe not.




#1. "Carl is Such a Homophobe! I Bet He's Secretly Gay!"



If you watch any movie or television show that focuses on gay characters, particularly those made by Alan Ball, you're going to eventually see the "Hates Gays Because He's Secretly Gay" character (see American Beauty). It's such a pop culture archetype that in real life when you see some guy at the gym expressing disgust at the whole gay thing, you automatically assume he's got some pictures of well-oiled dudes under his bed. Or actual dudes.

And we do see it in real life; staunch conservative politicians wind up soliciting sex in public bathrooms and sending pornographic emails to underage male pages.

"Yes, we have a meeting with the Congressman."

Why it is Bullshit:


OK, we admit this is sometimes true. There was even a popular study done in 1996 with 64 male college students, 35 of whom were homophobes (according to a survey they filled out gauging their attitudes on the subject). The researchers hooked a meter to their dongs (seriously) and had them watch lots of porn (yes, this happened--here's the damned link).

It was found that the majority of the homophobes would get at least a semi-boner while watching gay porn (where only about a quarter of the non-homophobes got aroused).

You can see right away what's odd about the numbers. All-told, nearly half of their total test subjects got at least semi-hard watching the gay porn. So... half the male population is secretly gay? That seems fairly unlikely.


Statistically speaking, 110 percent of the men featured in this picture are gay.

So, what is it? That guys who volunteered for this test were simply more likely to lean that way? You do have to wonder how dedicated they were to the anti-gay cause if they agreed to have some wires plugged into their tackle box while they sat and watched a movie called Rear Admiral.

Or maybe this was just some very well-made gay porn. Or, maybe this whole thing is just ridiculously unscientific.

Ding! We think we have a winner!

Hell, the above study even notes that gay lust and anti-gay rage can both give you a boner. We've got a confusion boner right now!

The main problem is that nothing in science says that "homophobia" is even a thing. It's not listed among the actual phobias. It's more of a slang term that gets used in popular culture to describe a huge range of attitudes, from people who have strong moral objection to homosexuality due to religious beliefs or upbringing, to people who physically find homosexual sex disgusting, to people who brim with an inexplicable rage toward gays.

Combine them all and you find that about half of the population thinks homosexuality is morally wrong (with intolerance skewing higher among older respondents, obviously). There is just no scientific criteria for which of those people are suffering from "homophobia."

It sounds like we're splitting hairs, but it's a great example of the kind of problem people run into when they decide to play amateur psychologist and "diagnose" the people around them. Remember, the guy who's spouting a particularly venomous anti-gay diatribe may be covering up for his own confused homosexuality, and may deserve only your pity. But there's a very good chance that he's simply a dick.

The Life Saving Animal Blood Worth $60,000 Per Gallon and the Truth About the Colour of Spider Blood


When it comes to spiders, people generally know two facts about them- that you swallow around eight of them per year and that their blood is bright blue. Fortunately, the former is absolutely not true at all, the latter, on the other hand, is mostly correct.

While it’s certainly true that spiders have blue liquid in their veins, the reality is a bit more grounded than is sometimes depicted, with the fluid a much more reserved shade of blue-ish green. Also, thanks to fact that spiders are (generally) so tiny and contain very little liquid, you’re not going to see too much of this after smashing one.

It should also be noted that, unlike humans, spiders have what is known as an “open circulatory system.” Essentially, their blood is allowed to mix with all the interstitial fluids within their bodies. The scientific term for this mixture is hemolymph, which is a combination of the Greek word for blood (HaĆ®ma) and the Latin word for water (Lymph) and it’s defined as: “The circulating fluid in many invertebrates that is functionally similar to the blood and lymph of vertebrates”



So what in this mixture is causing the fluid in the spiders to turn blue? Well, as you may recall, human and indeed all mammal blood is red because of the presence of the protein haemoglobin. The reason haemoglobin makes blood red instead of say, green is because of the presence of iron as an oxygen carrying pigment. (And to quickly debunk another popular blue-blood myth: No- deoxygenated human blood does not turn blue. It turns dark red. On a related note, the red juice you see in red meat at the grocery store is not blood.)

Spiders and other arthropods don’t have haemoglobin in their bodies, rather they have a protein known as haemocyanin, which contains copper instead of iron. However, haemocyanin isn’t bound to any cells in the creature’s body like haemoglobin is, instead it just grooves around their circulatory system at its leisure. When an oxygen atom binds itself to haemocyanin, instead of turning a deep shade of red, it will instead turn a pale blue-ish green, as copper is wont to do when it oxidises. The result in spiders is less than impressive because their bodies contain so little hemolymph to start with; in larger arthropods though, this effect can be quite stunning.

For example, the blood of the horseshoe crab is a delicate shade of baby blue thanks to the presence of haemocyanin, as is the blood of lobsters, crayfish and most mollusks like slugs and snails.

The Life Saving Animal Blood Worth $60,000 Per Gallon and the Truth About the Colour of Spider Blood

But what’s even more fascinating (and unique) about horseshoe crab blood is a chemical found in the amoebocytes of its blood. When this is exposed to a potentially dangerous foreign bacterium, it will immediately coagulate around the threat, rendering it harmless without actually destroying it. This effect is near instant and the blood can be used to detect a potential threat even if it’s diluted as much as one part in a trillion!

This effect is amazingly useful for detecting bacterial contamination in things like medicines and vaccines, or on medical equipment like needles, pacemakers, and numerous other items that are required to be sterile. In fact, no drug on the market today can be certified by the FDA unless it has been tested using this exact method (known as the Limulus amebocyte lysate test, in homage to the species of the crab- Limulus polyphemus). It’s by far the best way scientists are aware of for detecting whether a batch of medicine or vaccine has been compromised or not. As such, the blood of these crabs is worth a small fortune, selling for around $60,000 per gallon.

If you’re wondering how this blood is harvested, the crabs (over a half a million per year) are carefully picked up when they visit the shore for breeding purposes and taken in cooled trucks to certified labs where around 30% of their blood is drained, after which they’re returned to the sea. The blood cells are then separated using centrifugation. Next, the isolated cells are placed in distilled water where they will eventually burst (see Why Salt Preserves Meat for why this happens), releasing the valuable chemical inside. After being purified, it is then freeze-dried and stored to be used for testing.

The Life Saving Animal Blood Worth $60,000 Per Gallon and the Truth About the Colour of Spider Blood

Approximately 85%-97% of the crabs harvested for this purpose survive and go on their merry way after, with the crab’s blood levels returning to normal in under a week.

Even with the relatively good survival rates, all of this may sound harsh. But there is one type of animal besides humans that, at the least, is glad this property of horseshoe crab blood was discovered in 1956 by Dr. Frederik Bang- namely, the rabbit. Before the horseshoe crab blood method (LAL) of detecting microbial contaminants, a much less accurate and time consuming system involving testing on live rabbits was used. (In this rabbit pyrogen test, the rabbits were injected with a sample of the substance to be tested.)

So to sum up, if you’re not too technical in your definition of “blood”, spiders do have slightly blue fluid coursing through their bodies. Also, horseshoe crab blood may someday save your life, if it hasn’t already.

Eight Things You Didn’t Know You Could Do With Human Sperm

Eight Things You Didn’t Know You Could Do With Human Sperm

Sperm are single-purposed: They're optimized to get to an egg and inseminate it. But that doesn't mean there isn't more to this cell than meets the ovum. Sperm, along with its travelling companion, semen, are surprisingly versatile and adaptable substances. Here are eight unconventional things you can do with human sperm.
1. Skin softener
Sperm contains an anti-oxidant called spermine that is thought to diminish wrinkles, smooth the skin, and help with acne. Looking to take advantage of these much sought after attributes, a Norwegian company called Bioforskning (you can't make this stuff up) has synthesized the compound and is selling it as a facial cream. These, uh, spermine facials cost $250 and can be ordered through Townhouse Spa, or for $125 Graceful Services.
Eight Things You Didn’t Know You Could Do With Human Sperm

2. Cooking
Those looking to take their culinary skills to the next level should check out a book by Fotie Photenhauer called Natural Harvest, a collection of semen-based recipes. The book description:
Semen is not only nutritious, but it also has a wonderful texture and amazing cooking properties. Like fine wine and cheeses, the taste of semen is complex and dynamic. Semen is inexpensive to produce and is commonly available in many, if not most, homes and restaurants. Despite all of these positive qualities, semen remains neglected as a food.
This book hopes to change that.
Once you overcome any initial hesitation, you will be surprised to learn how wonderful semen is in the kitchen. Semen is an exciting ingredient that can give every dish you make an interesting twist. If you are a passionate cook and are not afraid to experiment with new ingredients - you will love this cook book!
3. Painting
Artist Martin Von Ostrowski is known for using bodily fluids as his paint mediums (including his infamous portrait of Hitler made from his own excrement). Back in 2008, Von Ostrowski put out an exhibition at the Gay Museum in Berlin in which he featured works painted with his own semen. A single painting requires about 40 ejaculations, which, given the size of the exhibition, suggests that he needed to ejaculate at least 1,000 times. Impressive! Von Ostrowski is able to keep these large quantities of sperm fresh by freezing it.
 4. Invisible ink
Back during World War I, the British Secret Intelligence Service (MI6) discovered thatsemen could act as an effective invisible ink. In June 1915, Walter Kirke, deputy head of military intelligence in France, wrote in his diary that chief Mansfield Cumming (yes), was "making enquiries for invisible inks at the London University." Rumor at the time had it that semen worked particularly well, and follow-up studies showed that it did not react to the usual methods of detection (including iodine vapor). It was also readily available for any intrepid secret service agent willing to make the sacrifice. The practice went into use, but it was noted that on at least one occasion that an agent had to be reminded to use only fresh supplies of the "ink" when people started noticing an unusual smell.
5. An anti-Depressant for women
Another potential application for semen is its use as an anti-depressant. This idea is quite controversial — but there is a modicum of scientific evidence to support it. A study done back in 2002 showed that women who were directly exposed to semen were less depressed. The researchers concluded that this was on account of mood-altering hormones in the semen being absorbed through the vagina — and that they had ruled out other explanations (New Scientistdidn't entirely agree — proposing a number of their own). That said, as Jesse Bering has pointed out, "there's good in this goo":
In fact, semen has a very complicated chemical profile, containing over 50 different compounds (including hormones, neurotransmitters, endorphins and immunosupressants) each with a special function and occurring in different concentrations within the seminal plasma. Perhaps the most striking of these compounds is the bundle of mood-enhancing chemicals in semen...Such anxiolytic chemicals include, but are by no means limited to, cortisol (known to increase affection), estrone (which elevates mood), prolactin (a natural antidepressant), oxytocin (also elevates mood), thyrotropin-releasing hormone (another antidepressant), melatonin (a sleep-inducing agent) and even serotonin (perhaps the most well-known antidepressant neurotransmitter).
6. Ovulation control
A recent study at the University of Saskatchewan has discovered that a protein in semen acts on the female brain to prompt ovulation — and that it's the same molecule that regulates the growth, maintenance, and survival of nerve cells. As a result, it's very possible that semen acts as a hormonal signal, working through the hypothalamus of the female brain and the pituitary gland. This in turn triggers the release of other hormones that signal the ovaries to release an egg.
7. Help with morning sickness

Okay, this is probably the last thing a woman is thinking about when she's suffering through morning sickness, but psychologist Gordon Gallup at SUNY-Albany, a male member of the human species who specializes in human reproductive competition and behavior, is suggesting that oral sex could serve as a kind of cure. Gordon theorizes that expectant women become ill and vomit because their bodies are rejecting the sperm's genetic material as something foreign and unfamiliar. His idea, which was presented at 2012 Northeastern Evolutionary Psychology Society, suggests that women can build up their immunity by ingesting the sperm of the baby's father. Gallup's conclusion is a bit hard to swallow, but there's also a scientific study supporting the idea that oral sex can reduce the incidence of preeclampsia in pregnant women.
 8. Archival storage of information

In what gives new meaning to the term "hard drive", human sperm — a transmitter of DNA — could be used to store information — a lot of information. We recently reported on a breakthrough by Sriram Kosui and his team at Harvard and Johns Hopkins in which he devised a technique for archiving information in DNA. The process, which takes advantage of DNA's data sequencing attributes, could be used to store as much as one petabyte of data (one petabyte = 1,024 terabytes) in a volume of 1.5 mg of DNA. Because genetic information can be packaged in three dimensions, that equates to a storage volume of about one cubic millimeter — so you'll finally have a secure and ironic place to store your massive digital porn collection.

What Your Zodiac Sign Says About Your Drinking Habits

What Your Zodiac Sign Says About Your Drinking Habits

We all know (or should know) that horoscopes are self-fulfilling prophecies and are, overall, a load of crap. However, despite this nonsense, it is always interesting to see if they hold any merit.

Which behaviors do you actually exhibit that are consistent with your zodiac sign? Do you think this is indicative of a truth or just happen to be a coincidence? Think what you want and think what you may.

While I believe this is all a load of bullsh*t, it is always fun to explore what different signs say about an individual. What’s even more entertaining is to see how members of different signs interact with one another in various situations. Which signs get along with others and which do not?

In true Elite Daily form, we are gong to analyze the drunken behaviors behind each astrological sign. Take this lightly, since we all know astrology means sh*t anyway.

Aries:

Known for having an outgoing and friendly demeanor, an intoxicated Aries will bounce from person to person, checking in and making sure everyone else is enjoying themselves as much as the Aries is.

If not, you can count on this person to buy you enough shots until you are on his or her level. If you are ever in a bad mood, this is definitely the person you want to hit up for happy hour.

What Your Zodiac Sign Says About Your Drinking Habits

Taurus:

Said to be one of the more loyal astrological signs, this person will be by your side no matter what. Need a good wingman for the night? This is whom you should be calling.

Be careful though because once a Taurus is blacked out, the stubbornness will be sure to emerge. If they don’t like your game plan for the night, rest assured they will not succumb to this peer pressure, especially when alcohol is involved.

This is also perhaps the worst person to get into a drunken altercation with, as they are temperamental by nature.

Gemini:

This symbol represents twins and is known for its multiple personalities. You know how difficult it is to go out and drink with someone whose demeanor can change at the drop of a hat?

Geminis cannot tolerate indecisive people, so you better know exactly what you are doing that night and who you are seeing. Be careful when you go out with Geminis, as they cannot stand to remain in one place for too long.

You know that one friend who disappears the second they black out? Chances are he or she is a Gemini.

Cancer:

This is the emotional waste case, the person who starts crying in a heap on the floor when something does not go his or her way.

Cancers display an array of emotions in any given situation, which is why drinking with them is not always ideal. One moment they are having the time of their lives and the next they are screaming at the bartender.

What Your Zodiac Sign Says About Your Drinking Habits

Leo:

Get the liquor flowing and a Leo’s mouth will not stop moving. Leos don’t hold back their opinions, regardless if they are offensive.

Everyone knows how chatty people start to get after they’ve thrown multiple shots back. Be careful when trying to put Leos in their place, as their natural role is similar to a lion: a leader.

Virgo:

You can find these perfectionists sipping wine at the end of the bar, solo, after a rough day at the office. These are not your ideal drinking partners, as they tend to keep more to themselves as opposed to a crowd of people. Dive bars? Yeah right.

Virgos are neat freaks and hate less than exceptional establishments. If you are looking for a classy night out on the town, then look no further than your Virgo friend.

Libra:

A Libra is perhaps one of the best people to go out and get hammered with. They are the happy-go-lucky types who always want everyone to have fun.

They are level-headed, which is a great quality to have when getting sh*tfaced. When your two friends get in a fight, you can always count on a Libra to mediate the situation.

Scorpio:

Give a Scorpio a flight of tequila and watch his or her opinions unfold. Scorpios do not hold anything back, which can be both a good and a bad thing.

However, they are the people who will drink with you throughout any given situation. The best part is they tend to hide their emotions, so you never have to worry about your Scorpio friend getting sh*tfaced and crying in the middle of the bar.


Sagittarius:

Be careful when partying with a Sagittarius, as he or she has a sharp tongue by nature. Alcohol and anger do not mix well, so you better watch what you say around these people.

As they drink throughout the night, you will notice how their flirtatious personality quickly emerges. Need a wingman or double date partner? This is who you are going to call.

Capricorn:

Capricorns, or should we say chameleons, are the perfect drinking buddies, as they can acclimate to whichever situation they are thrown into.

This is your carefree friend who just wants to have fun. They don’t care who, what, when or where. They only care how — how they are getting f*cked up.

Aquarius:

Be careful when drinking with an Aquarius because one moment everything can be going great as you take shots at the bar, but the moment you slip up and piss him or her off, sh*t will hit the fan.

People of this sign have quick-changing personalities, which makes getting intoxicated with them an experience all in its own.

Pisces:

A Pisces displays the most extreme of emotions, which makes getting hammered with him or her quite interesting. Be careful of Pisces’ mood swings because that one extra shot can really throw them over the edge.

When trying to go on a spontaneous drinking endeavor, a Pisces would be at the top of your list, as they are the type to go with the flow rather than fight the current.

Jewelry That Harvests Energy From Your Veins

Jewelry That Harvests Energy From Your Veins

Naomi Kizhner, an industrial designer and graduate student from Hadassah College in Jerusalem, has designed jewelry that theoretically extracts energy from the wearers own body. The ‘speculative’ jewelry is embedded into the person's veins and uses their blood to turn small wheels inside the device.

As Naomi notes, the jewelry is not meant to be a practical energy source, but a discussionpiece “about how far will we go to in order to ‘feed’ our addiction in the world of declining resources.”

The project is called 'Energy Addicts' and consists of three pieces of jewelry: The Blinker, The E-Pulse Conductor, and The Blood Bridge. On her website, she says "The work delves into a world in which there is a significant decline, which forces humanity to seek all the more forcefully for alternative ways of cultivating power. The suggested solution to the dilemma is based on the idea of biological wealth, harvesting energy directly from the body.”

Watch Naomi’s take on the world of energy consumption below.
