If time freezes at the edge of a black hole, does that mean that you could live forever if you could overcome the gravity? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world.

Answer by Viktor T. Toth, IT pro, part-time physicist, on Quora:

Whenever you think about time dilation in relativity theory, keep in mind that the theory is not about you. It is about what others see. As far as you are concerned, no matter where you are or how you move, time will always appear to pass as it always does.

So suppose you are in a super-fast spaceship. Every second of your life is a thousand years on Earth. Does this mean you live forever? Nope. You can still expect a normal human lifespan as measured by your own watch and calendar. Sure, billions of years would pass on the Earth in the meantime, but you will not experience billions of years. You will experience a few decades, like any human being would.

Or suppose you are deep inside a very powerful gravitational field. Extreme time dilation, right? But once again, it’s about what others see. Others, us here on the Earth, will see you age slowly and we will see your clock tick slowly. But as far as you are concerned, your clock will tick as it always does, and you will age exactly as fast as you would anywhere else.

So let me repeat the main point: Relativity theory is not about what happens to you. It is about what others, who are observing you, see.

I've been switching back and forth between my iPhone 6S Plus and our Google Pixel review unit, and I keep wishing I had the Pixel.

You should note that everything here is subjective. The iPhone has great features that the Pixel doesn't have, and the Apple ecosystem is in a league of its own.

But damn, the Pixel is good.

You should also note that I'm comparing the Pixel XL experience with my iPhone 6S and not the iPhone 7 series. That's because I have more experience with the 6S Plus, as it has been my phone for the past year and a half.

However, the iPhone 6S Plus isn't that much different, as a whole, from the iPhone 7. The performance is still comparable, and the iPhone 7's camera upgrades aren't as important as some of the Pixel's more functional features.

Here's what I think makes the Pixel a better phone than the iPhone:

The Pixel is lighter.

The Pixel is lighter.

My iPhone 6S Plus' weight (192 grams) never bothered me until I picked up the Google Pixel XL (168 grams). The iPhone 7 Plus is slightly lighter than the 6S Plus, at 188 grams, but that's a difference of only 4 grams, so I'd still consider the 7 to be heavy compared with the Pixel.

The Pixel's lighter weight has no ill effect on its reliability, and it's easier to manage in your hands.

The Pixel is slightly smaller but has the same screen size.

The difference is slight, but it's there and noticeable on a device you hold and use many times a day.

The iPhone is on the lower end of the screen-to-bezel ratio (67.7%) compared with the Pixel XL (71.2%).

The Pixel's screen is stunning.

The Pixel's design is more utilitarian than it is beautiful, but its AMOLED screen outshines the iPhone's Retina display.

Everything looks better on the Pixel than on the iPhone's LCD display. Pictures, videos, and apps pop with inky blacks and vibrant — but not oversaturated — colors, which makes for an overall more premium and modern look.

In the photo above (taken with the Pixel, by the way), the Pixel XL and the iPhone 6S Plus are showing the same picture on full brightness. The iPhone's LCD screen is nice, but the colors aren't as rich, and the contrast isn't as pronounced, as on the Pixel's display.

The iPhone 7 Plus also has a 1080p screen that's fine and sharp enough, but the Pixel's 1440p screen is sharper.

The Pixel has a clever way to add grip.

Antonio Villas-Boas/Business Insider

I don't like cases, but I have to use one for my iPhone. As nice as the iPhone's metal back and edges are, they don't offer any grip, and I've dropped and dinged my iPhone a couple of times as a result.

The glass inlay on the Pixel's back doesn't look particularly nice — it looks better on the white model — but it's a great grip for your index finger, and that makes the Pixel feel more secure in your hands.

Fast charging.

Fast charging.
SuperSaf TV/YouTube

The tech YouTube channel SuperSaf TV tested the charging times of the Pixel XL, the iPhone 7 Plus, and the Galaxy S7 Edge with the chargers included in each phone's packaging.

The Pixel XL was nearly 100% charged after two hours, while the iPhone 7 Plus was dragging its feet at 72%. The Galaxy S7 wiped the floor with the other two, having charged to 100% after an amazing one hour and 29 minutes. Still, the Pixel charged faster than the iPhone.

Charging speed is a huge deal, especially for a device that's designed to be portable and mobile. It means your smartphone can spend less time tethered to a charging cord. The Pixel's USB-C charging is faster, and it's one of the harder things to adjust to when switching back to the iPhone.

I can choose to make the Pixel work faster.


I can adjust Android to make it feel faster than iOS by cutting down or removing the animations when I open apps and swipe between screens.

Apple's iOS has a Reduce Motion option, but it seems to only change the default zoom-in and zoom-out animations when opening and closing apps to fade-in and fade-out animations. Apps don't appear to open or close any faster.

Pixel has better battery life, thanks to Android.

Android's Doze feature is exceptionally effective. It does a fantastic job of reducing the Pixel's power consumption when I'm not using it, compared with iOS on my iPhone.

I prefer Android overall.

I prefer Android overall.
Antonio Villas-Boas/Business Insider

I simply get along better with Android than iOS.

Apple still hasn't figured out how to show me notifications in iOS as well as Android. They're easier to manage from the Android lock screen, where I can clear notifications away with one swipe compared with iOS's swipe-and-tap to clear. I can also pull down on the notifications to peek at more details compared with iOS, which doesn't show me very much.

Notifications also manage themselves better in Android. For example, when I open a new email or Hangouts conversation on my computer, Android automatically clears those notifications on the Pixel, whereas they remain on my iPhone until I manually clear them.

It's also difficult in iOS to swipe up from the bottom of the screen, for things like changing the brightness, with the on-screen keyboard there. On Android, I can easily swipe down from the top of the screen to access the most important settings from any app, whether the keyboard is there or not.

The universal back button that simply brings you back to your most recent screen or page is incredibly useful because it's always in the same place. On iOS, the back button for apps and screens can differ from app to app.

There's also the "I can hide my apps in the app drawer and put them wherever I want on the home screen" customization argument, which has been a classic Android argument since its release.

Finally, for those who use a voice-activated assistant, Google's Assistant has proved to be far more advanced than Siri.

A new website and series of videos highlight several reasons to give up your Android phone and switch to iPhone.

Apple and Android may forever be locked in a fight for mobile domination, but they take very different approaches to their quest for market share. On the one hand, there are more than 2 billion active Android devices in use around the world. On the other, Apple makes gobs of money from selling just a handful of handsets.

But like the PC wars of the 90s, Apple isn’t content with such a slim slice of the market. While it has had a Move to iOS app in the Play Store for a while now, Apple is now taking the fight directly to Android users with a new campaign devoted to switching.

Head over to the iPhone tab on Apple.com and you’ll see a new box in the middle of the page. Called “Why Switch,” it declares that “Life is easier on the iPhone,” and offers 10 questions potential switchers might be asking:

  1. Will it be easy to switch?
  2. Is the camera as good as they say?
  3. Why is the iPhone so fast?
  4. Will iPhone be easy to use?
  5. How does iPhone help protect my personal information?
  6. What makes Messages so great?
  7. Can I get help from a real person?
  8. Can I switch at an Apple Store?
  9. What about the environment?
  10. Will I love my iPhone?

And finally, it asks, “Are you ready to switch?” while offering links to purchase all five of the phone models. The site also promotes Apple’s trade-in policy, boasting up to $260 in credits.

There is also a series of videos on Apple’s YouTube channel to highlight many of the points, including speed, ease of switching, and privacy. It’s unclear whether Apple plans on taking the campaign beyond the web, but it’s not too hard to see a TV or print campaign accompanying the site.

Earlier this year, Google unveiled its own switching site, coinciding with a new transfer tool that synced your contacts, calendar entries, and photos through Google Drive. It’s similar in practice to Apple’s Move to iOS app, but doesn’t require the installation of app you won’t need after the transfer is finished.

Apple ran a highly successful switcher campaign in the early 2000s, which used real people to tell stories about why they moved to a Mac. While Tim Cook has said upwards of 30 percent of new iPhone buyers are making the switch from an Android phone, Apple hasn’t previously launched an ad campaign targeted at Android.

Flip the switch: It’s no secret that Apple is looking for signs of growth. While the upcoming iPhone 8 will surely boost sales in the holiday quarter, Apple still needs to generate excitement during the rest of the year, which has proven difficult due to a steady stream of rumors and flagship competitors from the likes of LG and Samsung. But a new switcher campaign could be just what the doctor ordered.

Enter your budget and a number of your preferences and Teleport will match you with some fitting cities

if you’ve ever struggled to figure out where to live and work, you might benefit from Teleport, a website and app that recommends cities based on your lifestyle.

Trying the web browser version for myself, I prioritized places good for remote work and quality of life options including “tolerant society,” “near water” and “travel with ease.” (I skipped the cost of living questions; the past decade, I’ve lived in Copenhagen and San Francisco, two of the most expensive cities on the planet. I’m used to exorbitant expenses.) Under the city infrastructure options, I chose “car-free life” and ignored “school quality” and “less traffic” since neither really applies to my life. I was surprised when it suggested I move to Lisbon or Geneva, two walkable, cosmopolitan cities I’d never considered.

Teleport grew out of the founding team’s own experiences living in various cities around the world, often working remotely across cities and time zones in North America, Europe and Asia. The software company, which is constantly expanding its product line, began with Teleport Cities, a service that uses big data to determine where an individual should be based. (They are tight-lipped when it comes to specifics about the algorithm.) Since then, the group has developed tools, including Teleport Runway, which helps compare the costs of starting and running a small business in various locations, and Teleport Directory, a resource list for finding services and people in your next home city, as well as international moving checklists and blueprints for how to manage professional teams remotely.

Currently based in Palo Alto, Calif., Teleport co-founder and CEO Sten Tamkivi shares his story with Smithsonian.com.

Where did the idea for Teleport originate?

Teleport definitely grew out of personal pains. Between my two co-founders, Silver Keskküla and Balaji Srinivasan, and me, we had lived in a dozen countries already, and I personally had spent a large part of my career running teams spread between multiple cities. Most of our team knows the struggles of moving around all too well. [There are many aspects to] trying to stay informed about your next location and steps you need to take: the hours of research, 29 browser tabs open at a time, the lack of credible information and trying to remember everything that is important to you and whoever you're moving with.

Half of our team previously worked at Skype, which also plays a huge part in both what we are building as well as how we are doing it. Basically, if at Skype we were making the world a smaller place in metaphorical sense, at Teleport, we are getting to the next stage and moving people around physically. By the time we had 200 people, we already had 10 locations, so every week, there were some questions about where to hire the next people and where to open the next office.

teleport2.jpgTeleport co-founders Silver Keskküla (left) and Sten Tamkivi (right) (Teleport)

What’s the elevator pitch?

Teleport moves people to their best place to live and work, based on their personal needs and preferences. We help you plan your life across the current and future cities you want to work and live in, and get in touch with the communities, employers and governments to make the next move.

What’s the user experience for Teleport Cities?

You tell us about yourself: choose the life quality aspects that are important to you, and also reveal a little bit about your financial situation, such as your area of work and monthly rent budget.

Based on this, Teleport Cities gives you a list of cities that match your preferences, including a breakdown of your match score (qualitative features of a city), and budget differences (the hard numbers) compared to your current city. If you’d like, you can change your info, or add or remove some life quality settings to get a more accurate match list.

Once you’re happy with your preferences, you can go ahead and explore your top cities. Our city profile pages contain a huge amount of interactive widgets that break down information about every quality of life aspect in that city that you could possibly imagine.

Data is nice, but local experience is also great. For any other questions, we have an Ask a Local community, easily accessible from each city profile, where you can ask locals about living in a particular city.

teleport6.jpgTeleport Cities gives a user a list of cities that match his or her preferences, each with a score. (Teleport)

What is the geographic range? Is it limited to certain cities, with plans of expanding to others?

It's completely global. We kind of even ignore countries as a division on a map and think of cities or urban areas everywhere as our unit of management. We started out with the 100 most creative cities around the world, and have now reached 265. We add new cities based on user votes, both to avoid our own bias and to make sure our product is as versatile as possible.

A third of our users come from Europe, a third from North America and another third from everywhere else, mostly South America and Asia. We have a quarter of a million accounts signed up and executed over a million searches in 2016.

What types of preferences can a user select in a search?

There are about 300 different data dimensions involved in the product, but some of the most popular examples are cost of living, quality of education, tolerance towards minorities, environmental quality, cultural activities, job availability, labor regulations and economic growth.

teleport7.jpgThe tool provides a breakdown of each city's life quality score. (Teleport)

What are the most popular of your location optimization tools?

Teleport Cities is definitely our most used product, and the one we spend the most time developing. While at it, though, we’ve kept running into adjacent pains that our users need a solution for, and especially some that have been really easy to build as light little apps based on the data and infrastructure we already have for our core product.

Some of our more popular side products include Teleport Zen, an interactive moving checklist; Teleport Sundial, a coordination tool for remote teams; and Teleport Runway, a tool to calculate your startup’s runway budget and compare costs in different locations.

Are there any misconceptions about your suite of products?

Some people have been slightly confused at the sheer amount of products we have built in a very short time. I’ve even been invited to speak at a product conference on the topic of immaturely large product portfolios. While the Teleport Cities life search is our core, we’ve just felt a number of small, targeted apps on the side have allowed us to learn and experiment without bloating our core product with random features.

Luckily, we have a great user base that is very active in giving us feedback and letting us know immediately when something is wrong or hard to understand, which is great, because we can fix the issue as well as learn a valuable lesson.

The untold truth of Red Bull

Whether you're the type that can't imagine a trip to the grocery store or gas station without grabbing an energy drink or if you rely on them only for an occassional emergence pick-me-up, you're familiar with the distinct taste of Red Bull. It's gone from being the drink of choice for truck drivers in Thailand to a global phenomenon, and you might be surprised at some of the things about the drink — and its creators — that you've never heard.

Its inventor was from incredibly humble beginnings

Red Bull is pretty much everywhere today, which makes it easy to forget that it definitely hasn't been around forever, and its invention is actually an unlikely story.

The original Red Bull is called Krating Daeng, and it was created by an entrepreneur in Thailand. Chaleo Yoovidhya created the energy-imbuing blend in 1976, and it took the top spot among the country's energy drinks within two years. As the saying goes, timing is everything, and Chaleo's creation came when there was a surge in people who were trying to stay awake and productive. The economy was facing a nationwide industrialization, and its citizens needed something to help them make the transition from rural lifestyle to urban jobs — especially blue-collar ones. Truck drivers were among the first targeted by the brand, and its popularity skyrocketed.

Part of his success hinged on the idea that he wasn't just selling a product, he was building a brand. He also knew exactly where his clients were coming from, too, as he'd been there. Chaleo was born in 1923 to a family of Chinese immigrants who had moved to Thailand, and he counted things like duck farming among his early occupations. He founded his own company — TC Pharma — in 1956. It took almost another two decades before he started an energy drink revolution.

It went global thanks to an international toothpaste promoter

Krating Daeng wasn't an overnight, global success by any means, and it wasn't until 1987 that a completely unrelated business encounter turned it into Red Bull and introduced it to the world. Chaleo's company was working with importing product from a German toothpaste company called Blendax. When Blendax's marketing director sampled his licensee's energy drink, there was no looking back — especially after that marketing director, Austrian businessman Dietrich Mateschitz, struck upon the idea of forming a corporation specifically to bring the drink to the rest of the world.

After a bit of tweaking and translation that took a whopping three years to get just right, they started testing in the Austrian market first. Fifteen years later, the company was enjoying $1.3 billion in annual sales, all built on the shoulders of someone who had started out in the business of selling toothpaste.

It's been subject to nationwide bans

Introducing Red Bull to a global market wasn't a flawless, simple process, and even if you're from one of the countries that never had a problem putting the original Red Bull on store shelves, you've probably heard the concerns over what it does to a person's brain and body. In 2004, France raised concerns about the levels of caffeine Red Bull contains, and banned the import and sale of it completely. The ban was challenged on the grounds that it was interfering with the right to import products into the country, but based on a report from the European Court of Justice's Scientific Committee on Food that suggested more studies were needed to completely assess any health risks, the ban was upheld.

It wasn't until 2008 that the original, unmodified version of Red Bull was allowed to be imported to and sold in France, because continued testing couldn't find any evidence of the supposed health risks that had kept it out of the hands of French citizens until then.

France isn't the only one, either, and in 2014 Lithuania voted a new law into effect that took away a huge part of Red Bull's target audience: minors. The law forbid the selling of any high-caffeine energy drink (not just Red Bull) to minors.

The accusations of a conflict of interest in scientific studies

Decades after Red Bull was made available to most of the world and years after even France had gotten on board, there are still studies being done on potential risks associated with energy drinks. While other companies have also had their products targeted, it's Red Bull's influence that has some medical professionals concerned.

In 2014, Dr. Peter Miller of Australia's Deakin University published a piece in the BMJ that questioned just how honest some of these studies are. Specifically, he was concerned about investigations into what happens when you start combining energy drinks and alcohol, and whether it intensifies the affects of the alcohol. The problem, he claims, is that there are a number of studies that say Red Bull is completely safe. Read the fine print, though, and you'll find they're often financed by Red Bull themselves in what seems to be a complete conflict of interest.

Red Bull did provide a response, saying simply that no, there was no apparent increase in risks from mixing its product with alcohol. What they didn't respond to, though, were questions about providing placebos or approving studies. Other researchers have warned that studies are, in fact, rather incomplete by necessity. It's a case where laboratory conditions can't mimic real-life situations, since ethics laws place limits on just how much volunteers can be asked to drink. Those rules don't apply in real life, and that raises more concerns about just how accurate studies are.

Samples of Red Bull Cola tested positive for cocaine

Red Bull might be best known for its energy drinks, but in 2009, the company made headlines with another product. Their Red Bull Cola was making waves — and not in a good way — when testing in Germany found samples that contained trace amounts of cocaine.

News reports clarified the process behind making cola, which is made from the same coca plant that's notorious for its illicit byproducts. It's included in a number of energy drinks, but the manufacturing process removes the cocaine component… in most cases.

Even though the amount found was negligible — the German food safety department said it would take chugging an impossible 12,000 liters to get any cocaine-like effects from it — it was still banned in six German states. The ban wasn't universally supported, even within Germany, either, with Fritz Soergel, a representative from the Institute for Biomedical and Pharmaceutical Research saying that it was a completely inactive version of cocaine that was completely harmless. Still, no one likes to hear that something with cocaine is on their grocery store shelves, and the ban stood.

One company produces Red Bull flavors for the world
Getty Images

Everyone who's ever had a Red Bull knows exactly what it tastes like. It's an incredibly distinctive flavor, but you probably can't name it. No one has been able to really settle on just what the flavor is, although ideas range from things like liquid sweet tarts to cough syrup with added sugar. New flavors are a little more identifiable, with the release of cranberry, blueberry, kiwi, and even pink grapefruit flavors (depending on what country you're in). In 2015, Saravoot Yoovidhya, CEO of Red Bull manufacturers TC Pharma, admitted that in order to move forward they were going to have to keep up with the times, reevaluating their flavors and other choices. When China Daily reported on the changes on the horizon, they quoted Saravoot as saying, "We introduced everything — the production system, the flavors, the concept of our product, even the formula, using local teams. It has been 20 years now, and the market has changed a lot in that time. We need to make some adjustments for the future."

While that has meant introducing these new flavors, one thing that remains unchanged is the unique taste of the original Red Bull. There's a good reason for its consistency, too: they've never outsourced their flavors, and TC Pharma remains the only producer of that magical, mysterious, Red Bull flavor.

Those red bulls are actually gaur

The logo of Red Bull is iconic, and you might assume they're simply two red bulls, squaring off for a fight. They're actually animals called gaur, but you might also know them as Indian bison. Since 1986, they've been on the IUCN Red List because of their declining population, and they're incredible creatures.

Native to South and Southeast Asia, the gaur is the tallest of the world's wild cattle, and they all have the horns you see on the Red Bull logo, regardless of whether they're male or female. They're also among the largest still-living land animals, and in areas where they commonly come into conflict with people, they've actually adapted to nocturnal schedules in an attempt to avoid intruders. The presence of people encroaching on their land has changed their temperament, too, as animals that aren't frequently exposed to people are timid creatures, but those that have been confronted are known to charge. Ironically, even though the gaur on the Red Bull logo are shown charging each other, they're almost never seen fighting. Herd hierarchy and breeding rights are governed by size, and they rarely have to fight off predators, either. Instead, they rely on intimidation and numbers to dissuade predators — usually tigers, leopards, or crocodiles — from hunting the young or the elderly.

The heir to the Red Bull fortune is a wanted fugitive
Getty Images

In May 2017, a bizarre series of events continued unfolding, and the heir to the Red Bull fortune was right in the center. It started on September 3, 2012, when Vorayuth "Boss" Yoovidhya was accused of hitting a motorcycle policeman in Bangkok while driving his Ferrari. After dragging the policeman several meters, he sped away and later didn't show up in court to answer summons. According to his lawyers, he was detained by business, but the Associated Press uncovered a slew of social media posts that indicated he wasn't away on business (or sick, as was also claimed), but was instead flying around the world, hitting the best restaurants, and relaxing at luxury hotels. He was given one final chance to appear in court in May 2017, but instead fled the country again two days before he was due in court.

An arrest warrant was issued, plus his passport has been revoked and his immigration status in every other country has been invalidated. If convicted of the charges against him, it would mean a sentence of up to 10 years in jail, and the statute of limitations on that charge — reckless driving — doesn't expire until 2027. (Limitations on some of the other crimes have expired.)

According to his lawyers, he originally left the scene to talk to his father, and hadn't been drinking while driving in spite of a later blood test that indicated he had been. According to the statement issued by the police commissioner, "We will not let this police officer die without justice. Believe me."

They sued an 8-man brewery over their name
Getty Images

All companies are protective of their intellectual property, but Red Bull might have taken it a little too far in 2013 when they went after a small brewery in Norwich, England, for using a name they deemed too similar to their own. According to Red Bull, Redwell Brewing could easily be confused with the energy drink giant, and disputed their right to register their name and trademark.

Red Bull issued an official statement, saying, "The term "well" is merely descriptive and therefore of no distinctive character at all. Furthermore, the term "bull" and the term "well" share the same ending and just differ in two letters. The ending "ll" is identical and therefore the terms Red Bull and Redwell are confusingly similar from a visual as well from a phonetical point of view. The consumer will thus be confused as to the origin of the services."

The brewery, which boasted only eight employees and took their name from Redwell Street in Norfolk, had to sit down with Red Bull to agree that they wouldn't be making any energy drinks at any point in the future, and Red Bull allowed them to continue with their chosen name.

The insane false advertising lawsuit

There are plenty of incredible lawsuits that have been filed over the years, and in 2014 Red Bull found themselves the target of one. Benjamin Careathers sued the company for their slogan, which he deemed misleading. In spite of repeatedly seeing advertisements that claimed "Red Bull gives you wings" and consuming the energy drink in quantity, he was (presumably) shocked to find that he had not actually grown wings. He was also disappointed that he hadn't developed any intellectual or athletic super powers, so he decided to take them to court.

Shockingly, his accusation that the company had created their advertisements to deliberately mislead customers was met with something of a win. The suit claimed there was absolutely no scientific proof that a single Red Bull was any more effective than a cup of coffee, even though it was considerably more expensive when broken down to its core caffeine content, and marketed as being a superior product. Red Bull settled out of court, and agreed to pay every Red Bull consumer $10. The cost of the suit? A whopping $13 million, with $6.5 million going into a dedicated fund that was going to be paid out to consumers, $10 at a time.

They're behind an insane high-performance training center
Getty Images

While you might know Red Bull is linked with Formula One and extreme sports, you might not know they're also behind an insanely high-tech training facility in Santa Monica, California. Not only do trainers give their athletes one-on-one attention, but they do it with some pretty wild equipment.

There's a trampoline, for "air awareness", according to Sports Illustrated, and all the standard training equipment you might expect. But there's also a rig for neurological training, too, that measures brainwaves and helps athletes get a visual about what's going on in their heads as they're working. In layman's terms, it's getting "in the zone", and the training center actually has monitoring equipment that teaches athletes how to control their breathing and their focus to get there faster.

Other computers have sensors that allow trainers to look into their athlete's muscles to see how much oxygen is there, which helps them pinpoint training routines to get them to their peak efficiency. And then there's the cryosauna, a machine that athletes can hop into after training to get a freezing dose of cold that kicks hormones into overdrive and helps kick-start the recovery process.

At the end of the day, athletes experience everything from specialized training equipment for their chosen sport to getting an inside look at themselves, all in an attempt to really, truly, give them wings.

Researchers believe split between chimps and humans occurred in eastern Europe, not Africa

A jawbone discovered by German troops in Athens during the Second World War could be evidence that apes and humans diverged 200,000 years earlier than the current theory says.

Chimpanzees and bonobos are the nearest known relatives to humans, sharing 99 per cent of our DNA. It's believed that we split between five and seven million years ago. 

However, researchers analyzing two fossils — a jawbone from a German museum and an upper premolar from a collection in Bulgaria — concluded their ages to be roughly 7.2 million years, and belonging to a pre-human.

But there's another significant finding: that human split occurred in the eastern Mediterranean and not Africa, as it is believed.

Pre-human roots

The researchers came to the conclusion after analyzing the roots of the teeth preserved in the fossils, named Graecopithecus freybergi.

"While great apes typically have two or three separate and diverging roots, the roots of Graecopithecus converge and are partially fused — a feature that is characteristic of modern humans, early humans and several pre-humans including Ardipithecus and Australopithecus," Madelaine Bohme from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tubingen explained in a statement.

This came as a bit of a surprise to the researchers, who used computer tomography to examine the interior of the roots, which were, unlike the external teeth, in pristine condition. This method allowed a more accurate dating than techniques used in other fossil findings, such as Australopithecus and Ardipithecus, two of the oldest known pre-humans.

"It's an important advance," David Begun, a paleoanthropologist from the University of Toronto and co-author of the paper that appeared in PLoS One, told CBC News. "Because it's not so much that it's older — because it's not hugely older — but that the date is really a good, solid date."

Begun also noted that, because Graecopithecus is so old and no limb bones were found, it's not known whether it was bipedal or used arms and legs to move around.

Skepticism is likely

This conclusion is likely to draw some criticism: the divergence of apes and humans is believed to have taken place in Africa roughly six million years ago. Suggesting instead that it occurred in Europe is not a popular theory.

Begun said that he's already heard some skepticism about the group's findings. 

"People who are skeptical … will say that it evolved in parallel," Begun said. "But that's a special pleading for people who just can't believe … that chimps and humans could have diverged outside of Africa. But there's no reason to start with that premise at all."

A second paper published in PLoS One highlights the geological evidence to support a climate similar to present-day Africa. Giraffes, antelopes and even rhinoceros lived in that region for some time.

The drought-like conditions may have played a role in the splitting of chimps and humans. Changing conditions may have forced the animals and pre-humans toward the equator, to Africa.

Before this finding, the oldest known pre-human was Sahelanthropus from Chad.

Most of us have spent a lot of time surfing through loads of videos on YouTube. Now we might have our own preferences over the kind of videos we like to watch on the Google owned video platform, yet the basic fundamentals of the website remain the same.

Built on that, there are set methods to help you surf through those videos in a smarter way. Have you ever wanted to watch a video, the name or information of which you cannot recall correctly? A song that you feel like listening to but don’t remember the name of?

In any such case, these simple YouTube tips and tricks will help you find your way to that exact video that you want to watch. Playing on the YouTube search parameters, these hacks are as follows:

1. Let YouTube guide you

This one’s a no-brainer. Can’t recall the complete name of a video but know a few keywords? Use the YouTube search bar to type any known keyword and YouTube will present suggestions related to it.

Remember that YouTube has a complete track of your previous activities on the website. This means that it knows what kind of videos you usually like to watch.

This, combined with the ‘most-searched for’ videos on those keywords will present to you a pretty accurate list of suggestions. Chances are, you will find what you are looking for through these YouTube suggestions.

Note: YouTube creates a transcript for every video uploaded on it. This means you can search for a music video by typing in the lyrics of the song instead of the name. Same goes for other videos as well. The acuracy of the search results may vary though.

2. Use YouTube Filters

Filters are a great way to narrow down on your search results. As soon as you make a search, a Filter option on the top of the result column will let you put in advanced filters on your search.

The filters are based on the Upload Date, Type, Duration and the Features that you expect in your video. The ‘Features’ option will help you look for only HD, Only 4K, with subtitles and more such options in your search results.

NOTE: You can also activate these filters using commas in your search results. E.g. type in ‘Messi, Month, HD, Short’ in the search bar to find videos on Lionel Messi uploaded in HD in the last one month and which are short in duration.

3. Use + and – in your search results

These are called the Boolean operators. YouTube search allows you to add and subtract keywords from your search using the + and – symbols respectively. This is especially handy when the keywords you are using have an exact match with something else on the internet world.

Try searching ‘Donald’ on YouTube. You will mostly get search results catering to ‘Donald Trump’ or ‘Donald Duck’. What if you are looking for an entirely different ‘Donald’?

You can type in ‘Donald –Trump –Duck’ and the results will not contain any videos catering to those two keywords.

Similarly, the + operator can be used to include additional keywords into your search.

4. Force exact match using “ ”

At times YouTube shows matching results instead of the exact same keywords. As an example, upon searching for ‘Photography’, YouTube will also show results for ‘Photographer’ or other such deviated but related words.

To restrict the search results to the exact same keyword, you can use double inverted commas around the keyword. This will make YouTube look for the exact same word in the title or the description of the video.

This makes more difference when the ‘sort by’ option is set to anything other than ‘Relevance’.

5. Use ‘intitle’ to find keywords in video title

If in case you remember a few words from the title of the video that you had watched earlier or can make a wild guess about it, ‘intitle’ comes in quite handy.

The string command will give preference to search results that have the keywords that you have placed after the command, in its title rather than the description. Limited but useful results can be garnered out of this simple trick.

Whether you're suffering from the blues or simply experiencing a dip in morale, getting a boost of happiness is always a welcome feeling. With endorphins being one of our brain's major pathways to joy, it can be dire if you're unable to participate in the things that release it into your blood stream, like exercising or laughing with friends.

Google Cloud launched a new Internet of Things management service today called Google Cloud IoT Core that provides a way for companies to manage IoT devices and process data being generated by those devices.

A transportation or logistics firm, for example, could use this service to collect data from its vehicles and combine it with other information like weather, traffic and demand to place the right vehicles at the right place at the right time.

By making this into a service, Google is not only keeping up with AWS and Microsoft, which have similar services, it is tapping into a fast-growing market. In fact, a Google Cloud spokesperson said the genesis of this service wasn’t so much about keeping up with its competitors — although that’s clearly part of it — it was about providing a service its cloud customers were increasingly demanding.

That’s because more and more companies are dealing with tons of data coming from devices large and small, whether a car or truck or tiny sensors sitting on an MRI machine or a machine on a manufacturer’s shop floor. Just validating the devices, then collecting the data they are generating is a huge undertaking for companies.

Google Cloud IoT Core is supposed to help deal with all of that by removing a level of complexity associated with managing all of these devices and data. By packaging this as a service, Google is trying to do a lot of the heavy lifting for customers, providing them with the infrastructure and services they need to manage the data, using Google’s software services like Google Cloud Dataflow, Google BigQuery, and Google Cloud Machine Learning Engine. Customers can work with third-party partners like ARM, Intel and Sierra Wireless for their IoT hardware and Helium, Losant or Tellmeplus for building their applications.

While the company bills itself as the more open alternative to competitors like AWS and Microsoft Azure, this IoT service is consistent with Google’s overall strategy to let customers use both its core cloud services and whatever other services they choose to bring to the process, whether they are from Google itself or from a third party.


The solution consists of two main pieces. First there is a device manager for registering each of the “things” from which you will be collecting data. This can be done manually through a console or programmatically to register the devices in a more automated fashion, which is more likely in scenarios involving thousands or even tens of thousands of devices.

As Google describes it, the device manager establishes the identity of a device and provides a mechanism for authenticating it as it connects to the cloud, while maintaining a configuration for each device that helps the Google Cloud service recognize it.

The second piece is a “protocol bridge,” which provides a way to communicate using standard protocols between the “things” and the Google Cloud service. It includes native support for secure connection over MQTT, an industry-standard IoT protocol, according to the company.

Once the device is registered and the data is moved across the protocol bridge, it can flow through processing and eventually visualization or use in an application.
