This is a view of Enceladus, Saturn's sixth-largest moon, taken by the Cassini spacecraft.

New research from NASA’s Cassini mission has all eyes on Enceladus, Saturn’s sixth-largest moon. The research, recently published in Science magazine, indicates that plumes of vapor escaping from cracks in the moon’s icy shell are full of molecular hydrogen, the fuel for microbial life.

As Scott Bolton, a co-author and mission co-investigator from the Southwest Research Institute, explains: “Hydrogen’s the most common element in the whole universe, but we don’t expect a lot of it sitting on Enceladus.” That’s because Enceladus is too small to trap large reserves of hydrogen in its gravity field, he says.


The inference, of course, is that hydrogen is being produced somewhere on the Saturnian moon. But how? Bolton and his colleagues have an idea — one that could link the global ocean beneath Enceladus’ ice shell with the life-sustaining deep oceans of Earth.

“The idea that we’ve proposed — and we’ve researched a lot of different ideas trying to come up with an alternative theory — is that actually there’s hydrothermal activity going on deep in the ocean on Enceladus, and it may be producing white and black smokers, kind of like what we see on Earth,” Bolton says.

He explains that on Earth, smokers are deep hydrothermal vents that put out white or black “smoke” underwater, depending on their sulfur content: “Basically, what you have is you have minerals that are very rich in iron interacting with water.” That chemical process forms new minerals, he says — and releases hydrogen.

“In other words, under the deep sea, the water meets the rock, and some chemistry occurs, and hydrogen is released,” he explains. At least, that’s how it happens on Earth — and Cassini data has already shown that the ocean on Enceladus lies above a rocky core.

On Earth, scientists believe that hydrothermal vents were an early source of life. Today, the areas around deep sea vents teem with species that we’re still discovering.

“You don’t need any sunlight at all,” Bolton says. “You just have the microbes basically feeding off of this hydrogen, and that’s its energy source. And around that region on the Earth in these hydrothermal vents, you find little spider crabs, little shrimp, all kinds of different kinds of mussels.”


To find a shrimp in Enceladus’ ocean would take a submarine, but Bolton says there’s another place we can look for life: in the water vapor spewing through cracks in the moon’s ice hull.

“If you can fly a spacecraft through that water mist, you can go in and measure whether there’s microbes, and amino acids, and other kinds of things that might be present in that water,” he says.

Bolton says that a follow-up probe to Enceladus hasn’t yet been approved, but a mission to one of Jupiter’s moons, Europa, is currently in the works. “It would, hopefully, fly through these plumes,” Bolton says.

“We’ve seen some plumes coming out of the ice of Europa through Hubble telescope images. And so we would look for something similar as to what we just saw on Enceladus, and even more.”

UPDATE: A previous version of this story incorrectly stated Europa was a moon of Saturn, it is a moon of Jupiter.

Lots of people think that the best way to become successful is to pick up lots of new habits and skills. While this can help, sometimes the best thing you can do is give up the things that distract you from your goals.

Instead of adding more things to your life, try removing some negative things that hold you back from success. Some are very easy to give up, while others require a little more time and effort.

Here are 8 things that you should remove from your life to be more successful:

1. Remove Excuses

Successful people don’t try to blame their family, their friends, their boss or their co-workers for their life. Instead, they understand that they are fully responsible for their own life and situation. They see this as a good thing as it means that they hold the power to significantly improve their life. When you make up excuses you are lying to yourself, which will hold you back from achieving your goals.


2. Remove Perfectionism

Perfection is unattainable, so trying to achieve it is a waste of your time. Instead of worrying about mistakes that you have made or physical flaws that bother you, simply focus on trying to better yourself with small steps. No one is perfect, but anyone can make the decision to be a better person.

3. Remove Fear

Lots of people make themselves smaller without realizing; they keep quiet during discussions when they want to say something; they avoid taking risks; and they always think about the worst-case scenario. This fearful attitude will stop you from achieving your full potential, so remove it from your life and be brave instead; speak up, voice your thoughts and actively chase your dreams and goals.

4. Remove The Need To Control Everything

You can’t control everything, and trying to do so is a futile task. It won’t help you to become more successful, but it will make you feel stressed, upset and frustrated. Instead of trying to control everything around you, make an effort to care less about the things you can’t control and focus on the things that you can.


5. Remove A Fixed Mindset

Lots of people have a fixed mindset and they make no effort to learn more or change their perception. This makes it hard for them to become more successful as their mindset is stuck in the past. Try to embrace knowledge and learning, and remember that you can always become wiser.

6. Remove The Desire For Overnight Success

Some people believe that the majority of successful people became successful overnight, or that they became successful by chance. While luck can certainly play its part, you can’t rely on luck to become successful. In reality success takes time and dedication, so you should plan for the future as well as the day ahead of you.

7. Remove Toxic People

If the people around you are negative and pessimistic, over time you will start to become negative and pessimistic too. Remove the toxic people from your life and replace them with optimistic, supportive people who genuinely care about you and your dreams. You will find that you are more motivated to work on your goals, and you will be happier and less stressed.


8. Remove The Need To Say Yes (When Really You Want To Say No)

Some people struggle to say no to the people around them, even if they want to say no. This normally means that they end up wasting time doing things that they don’t want to do, and other people might start to take advantage of them. Be brave and say no when you want to; only you can make your dreams a priority, and it is difficult to do that if you are too busy helping other people with their dreams.

In this weekly series, LiveScience examines the psychology and sociology of opposite human behavior and personality types.

Lying — like it or not — is a part of everyday life. Most of us will bend the truth every now and then, with even the most honest person telling the occasional "white lie" to avoid hurting someone else's feelings.  

Yet some people, called pathological liars, utter untruths constantly and for no clear reason. Their behavior confounds scientists and oftentimes themselves. 

"Pathological liars have a pattern of frequent, repeated and excessive lies or lying behavior for which there is no apparent benefit or gain for the liar," said Charles Dike, clinical professor of psychiatry at Yale University and medical director of the Whiting Forensic Division of Connecticut Valley Hospital.

On the opposite end of the spectrum are those rare individuals who might be described as "pathological truth-tellers." These people forego socially convenient and appropriate fibs to speak the unvarnished, upsetting truth.

Intriguingly, this "lying handicap" is a common feature of the developmental disorder high-functioning autism and Asperger's Syndrome.

"People with Asperger's have a tendency to be very blunt and direct — they can be honest to a fault," said Tony Attwood, professor of psychology at Minds & Hearts, an Asperger's and autism clinic in Brisbane, Australia


Psychology and neuroscience have provided clues as to why some people lie up a storm while others have difficulty dissembling or detecting it in others. These contrasting extremes can help us learn about the default human mode of lying on a daily basis to avoid insult, get out of trouble or exploit others.

"If you define lying as 'statements intended to deceive,' then yes we all do lie, every day," said Dike.

Liar, liar

In psychiatric circles, pathological lying goes by the fancy name pseudologia fantastica, though it is not yet recognized as a distinct disorder.

What puzzles most about a pathological liar's behavior, Dike said, is that it is counterproductive. Dropping flagrant whoppers can cause trouble in jobs, relationships and even with the law through self-incriminations.

Stranger still, the lies can be blatantly see-through in their bogusness. "Not only is there no benefit to the lies, but the lies most of the time are easily disprovable," said Dike.

Dike offers an example of a coworker declaring he has a flight later that day. The co-worker is not trying to shirk a meeting, however. As the day goes on and the coworker remains in the office, he adds to the lie by announcing that the flight was cancelled. The pattern of falsities then continues. "The next day, there is some new story," said Dike.

Anecdotally, many of us will recognize this sort of behavior, though at present there are no good statistics for the prevalence of pathological lying. "What's clear," Dike said, "is that it's not uncommon."

A mind for facts

While acting in this manner makes no sense to most of us, it is essentially impossible for people with Asperger's. Patients have expressed to Attwood puzzlement at why ordinary people lie with such frequency.


To boot, people with Asperger's have trouble detecting falsity in words and actions. "They often think other people are as honest as they are, which leaves them vulnerable and gullible," said Attwoord.

Asperger's is characterized by impairment in social interactions and restricted interests. (A well-known television character who manifests much of the behavioral profile of someone with Asperger's is Dr. Sheldon Cooper on "The Big Bang Theory.") Attwood noted that these individuals have an "allegiance to the truth, rather than people's feelings."

Key to proper socialization and its subtleties is "theory of mind," the ability to attribute mental states to other individuals. "Theory of mind is determining what others are thinking, feeling or believe," said Attwood.

Asperger's patients tend to have a poorly developed theory of mind, which presents them with great difficulty in empathizing with others. More positively, this trait makes it tough to construct deceitful ruses, and those with Asperger's who do learn how to lie often do so badly, said Attwood.

Brain scans using functional magnetic resonance imaging (fMRI) have revealed a basis for this deficit. In Asperger's patients and autistics, there is less activity in parts of the "social brain," such as the prefrontal cortex. "In Asperger's,that area is dysfunctional," said Attwood. "Areas of the prefrontal cortex that should light up don’t in fMRI."

Natural born liars

To an extent, it would seem then that humans are wired to trick their fellows. In our closest primate relatives, who also have sophisticated social structures in which they live, deception is rife. Chimpanzees for example will purposefully mislead troop members away from a tasty food source and then return later to gobble it solo.

Researchers have discovered that the more conniving a primate species, the bigger its brain. (It therefore makes sense that with our giant brains, humans are veritable founts of hogwash.) The faculties of memory and abstraction needed to mince language and appearance so as to deceive require a lot of brainpower, researchers have learned.

Interestingly, brain scans have revealed that the prefrontal cortexes in frequent liars are built differently from those in a typical brain. A 2005 study showed that liars had 22 percent more "white matter" than average, as well as about 14 percent less "gray matter." The former acts like wiring in the brain, while gray matter cells in this region play a role in impulse control.

"If you have more white matter, you are more able to manipulate information and words," said Dike. "You can weave thoughts in ways others probably can't."

Dike, who was not involved in the 2005 study, pointed out that it was conducted on criminals and people with antisocial behaviors who lie with purpose, unlike pathological liars. Indeed, the motivation behind pathological liars' duplicity remains another big mystery.

Researchers speculate that pathological liars experience some sort of psychological excitement from fooling others. "There has to be some sort of internal satisfaction that makes them go on with this behavior, but no one knows for sure," said Dike.

Some everyday innovations as varied as a solid golf club and a high-quality selfie owe their existence to NASA technologies.


NASA published its 2017 edition of "Spinoff" — a profile of 50 commercial technologies originally designed for NASA missions and research.


Since 1976, NASA has published an annual document introducing run-of-the-mill items inspired by NASA innovations.


Here are seven of the most common objects on this year's list.


1. Crash-test cameras


1. Crash-test cameras

NASA needed high-speed, rugged cameras to record parachute testing for its landing systems.


The agency reached out to the California-based company Integrated Design Tools, which built a camera that could record 1,000 frames a second and immediately store the data.


That same technology is used in cameras that record vehicle crash tests.


2. Laser imaging: from space to underneath soil


2. Laser imaging: from space to underneath soil


NASA uses laser-imaging technology, known as LIDAR, on missions in outer space. LIDAR, which measures distances using laser light, can be used to develop high-resolution maps, among many other things.






NASA helped design smaller versions that are used on the ground. Archaeologists use them to help unearth artifacts. LIDAR is also being used in autonomous-driving technology.


3. From a screw thread to golf clubs


3. From a screw thread to golf clubs

It turns out that spacecraft design and golf-club engineering have some similarities.An innovation called the "Spiralock" is an advanced screw thread designed by the Holmes Tool Company.


NASA sought the company out because it needed an advanced screw that could withstand the rigors of a space launch.It is being used in golf clubs, too.


4. Brain-surgery tools


4. Brain-surgery tools


Neurosurgeons employ bipolar forceps, which use electricity to cut and cauterize tissue. But electricity in the forceps generates extra heat that must be dissipated to avoid damaging healthy brain tissue.


A company called Thermacore has a solution that NASA had been using since the early days of space flight. Heat pipes. A scaled-down version was created for bipolar forceps, helping to ensure the safety and effectiveness of neurosurgery.


5. Earthquake protection


5. Earthquake protection

A NASA-developed technology that used liquid fuel to prevent vibrations in the Ares 1 rocket was adapted to help stabilize buildings and bridges during earthquakes.






Now the NASA-derived technology, licensed by the engineering firm Thornton Tomasetti for commercial use, has been installed on a new building in Brooklyn, New York.


6. Fertilizer


6. Fertilizer


NASA helped Florikan, a fertilizer company in Florida, develop a fertilizer that doesn't dissolve too quickly, ensuring that plants get the right amount of nutrients from the fertilizer at the right time.


That fertilizer is now being used around the world — and in space.


7. From space photography to selfies


7. From space photography to selfies

You are using NASA-derived technology when you take a picture with your smartphone.A sensor adapted from complementary metal-oxide semiconductors was developed by NASA engineer Eric Fossum in the 1990s.


Though the semiconductors have been used in computers for years, NASA says Fossum was the first person to successfully adapt it for picture-taking.

LIFE probably does not exist on Mars as there is no water on the surface of the planet, a new study found.

A new study of meteorites that have crashed into the surface of the Red Planet over millions of years has found none showed signs of rust, suggesting there is no liquid present on Earth’s neighbour.

Our Neightbouring planet still harbours plenty of secrets, but alien life may not be one of them

There is less moisture on Mars than in the driest place on Earth – the Atacama Desert in Chile and Peru.

Some weather stations in this region have received no rain for years, while another station reports an average of one millimetre per year.

An international team of planetary scientists led by the University of Stirling suggested rust free meteorites showed Mars was incredibly dry and has been for millions of years.


The findings showed how difficult it would be for life to exist on Mars today as Earth’s nearest neighbour is the primary target in the search for life elsewhere.

Dr Christian Schröder said: “Evidence shows that more than three billion years ago Mars was wet and habitable.

“However, this latest research reaffirms just how dry the environment is today.

“For life to exist in the areas we investigated, it would need to find pockets far beneath the surface, located away from the dryness and radiation present on the ground.”

A study last year using data from the Curiosity Rover investigating Gale crater suggested very salty liquid water might be able to condense in the top layers of Martian soil overnight.

But the lecturer in environmental science and planetary exploration and science team collaborator for the Mars Exploration Rover Opportunity mission added: "But, as our data show, this moisture is much less than the moisture present even in the driest places on Earth."

The Mars Exploration Rover Opportunity provided data on a cluster of meteorites at Meridiani Planum - a plain just south of the planet's equator and at a similar latitude to Gale crater.

The study comes as the European Space Agency's Schiaparelli lander prepares to land on Mars to search for life

The search for life on Mars might just center around a strange funnel-shaped surface feature inside a crater, scientists say in a new study. Located in what is known as the Hellas depression, the feature could hold the “ingredients of life.”

The Daily Mail reported last week that a new study suggests that volcanic activity on Mars might have been a key contributor to the odd funnel depression that could be Mars’ best chance to host living organisms. Scientists have believed that a volcano located beneath a glacier on Mars’ surface created the Hellas depression, but new data taken from stereoscopic images and digital elevation models indicates that the formation is not only volcanic in origin, it might be similar to “ice cauldrons” on Earth. Such a formation could create an environment warm enough to host liquid water and chemical nutrients that might support life.

Ice cauldrons are found on Earth in places like Iceland and Greenland, created when volcanoes erupt under an ice sheet. On Mars, these same conditions potentially could host life.

Joseph Levy, a research associate and lead author of the study from the University of Texas Institute for Geophysics, explained the reasoning behind the study’s site choice.

“We were drawn to this site because it looked like it could host some of the key ingredients for habitability – water, heat, and nutrients.”

The Hellas depression, as noted, is located in a crater at the edge of the Hellas basin. Ancient glacial deposits surround the feature.

Nor is the feature, which was first discovered in 2009 in images from the Mars Reconnaissance Orbiter, unique. It is similar to a depression in the Galaxias Fossae region.

“These landforms caught our eye because they’re weird looking. They’re concentrically fractured so they look like a bull’s-eye. That can be a very diagnostic pattern you see in Earth materials,” Levy admitted.

The study concluded that the two funnel structures were formed in different ways. The Galaxias Fossae depression seems to be a product of an impact, while the Hellas depression showed several indications of volcanism.


Levy and his fellow researchers suggest that such depressions on Mars should be considered as prime locations for the search for life on the Red Planet. The Hellas formation is of particular interest due to its possible volcanic origins and the potential for life-fostering properties.

The search for life on Mars might have received a boost or perhaps even a confirmation (or denial) of its existence last month had the Rocosmos and European Space Agency’s lander been able to continue its mission on the planet’s surface. Called Schiaparelli, the lander was an astrobiology project specifically designed to search for life on Mars. As the Inquisitr reported, Schiaparelli exploded on impact with the surface on October 19, a victim of its parachute deploying too early (although conspiracy theorists oddly accused NASA of shooting down the craft to maintain its scientific dominance).

Beyond Mars, the search for life outside the bounds of the Solar System received help from the Parkes Observatory in Australia this week. According to Space.com, the telescope joined the $100 million Breakthrough Listen project, the astronomical initiative launched by Russian billionaire Yuri Milner, becoming the third telescope in the line-up that includes the Green Bank Telescope in West Virginia and the Automated Planet Finder at Lick Observatory in Northern California.


“The addition of Parkes is an important milestone,” Milner said in a statement. “These major instruments are the ears of planet Earth, and now they are listening for signs of other civilizations.”

The Parkes dish’s first Breakthrough Listen observations were received from the nearest star system, Proxima Centauri, where a planet has been detected that exists in the star’s habitable zone.

With the results of the past presidential elections, many Americans are thinking about the future of life in the Red Planet. However, a new study showed that it very difficult for life to exists on Mars today. 

The study, published in the journal Nature Communications, showed that the very salty water that can condense in top layers of Martian soils is much less than the moisture present in the driest places on Earth.

"Evidence shows that more than 3 billion years ago Mars was wet and habitable. However, this latest research reaffirms just how dry the environment is today," said Dr Christian Schröder, Lecturer in Environmental Science and Planetary Exploration at the University of Stirling and Science Team Collaborator for the Mars Exploration Rover Opportunity mission, in a statement. "For life to exist in the areas we investigated, it would need to find pockets far beneath the surface, located away from the dryness and radiation present on the ground."

For the study, the researchers examined a cluster of meteorites at Meridiani Planum using data from the Mars Exploration Rover Opportunity. By studying the chemical weathering rate of the meteorite on Mars, the researchers were able to demonstrate the lack of water on the surface of the red planet. 


The researchers found out that it would take at least 10 and possibly up to 10,000 times longer for rust to form from the metallic iron present in meteorites on Mars to reach the same levels of rust formation than in the driest desserts of Earth. Rust formation is chemical weathering process that depends on the presence of water.

With their findings, the researchers have reasons to believe that the current environment of the Red Planet may not be suitable for life. Furthermore, evidence points out that Mars is incredibly dry and has remained to be as such for millions of years.

With over 1.5 million apps available on the app store alone, it can be confusing to determine which ones you should download and which ones you should ignore. There’s just too much noise out there today.

Not only are there more apps than we can fathom, but there’s only so much time and mindspace we have to consume all of them. This is why it’s increasingly important to filter out the apps and websites that will have the biggest impact in our lives, with the least amount of effort.

This post is dedicated to delivering that value. Here are 17 apps and websites that can change your life.

1. Headspace

Need a peace of mind? Facing stress or anxiety? Or maybe there’s just not enough time of the day to smell the roses.

Headspace may be the answer for you busy bees. With only 10 minutes of your time, this app will guide you through a simple, yet powerful, meditation practice that is guaranteed to help you smile more, sleep better, and love better.

Don’t have 10 minutes?

You may need this more than you think. As the popular Zen proverb goes, “You should sit in meditation for twenty minutes every day — unless you’re too busy. Then you should sit for an hour.”


2. Codeacademy

Coding has become so in demand these days that understanding the basics of coding — such as HTML, CSS, or Javascript — is as standard as knowing how to use Microsoft Powerpoint.

Lucky for us, there are great websites like Codeacademy that are 100% free and are able to guide you through each step of the way — even if you start from scratch. They include practical projects that you can build to apply what you’ve learned, and give you immediate feedback to correct your mistakes. Talk about immersion!


3. Rype

Have you heard of Netflix? Well, think of this as Netflix for language lessons.

Rype offers unlimited one-on-one lessons (in Spanish only right now), live online classes, and premium video lessons, for a simple membership fee.

Booking a lesson takes less than 15 seconds, and lack of time will never be an excuse for you again. Take a look.


If you want to dip your feet into the pool, Rype also offers free live Spanish classes that you can attend. Check out the upcoming live classes.

4. Uber

This app probably needs no introduction.

Despite some sketchy and questionable lawsuits that Uber has been through, you can’t question the convenience and value that this app provides. Whether it’s providing a side hustle for struggling artists and entrepreneurs, or saving us all a major hassle of calling a cab, Uber is a game changer.


5. F.lux

If you’re like me, then you probably spend a majority of your day staring at a screen, whether it’s your desktop, tablet, or mobile. Eye strain is one of the most common problems we face, and F.lux has solved this issue.

This free widget adjusts the lighting of your screen, depending on the time you set in the preferences, so you’re no longer staring at a flashlight pointing towards your face. Say goodbye to tired-looking eyes!


6. Spritz

When Bill Gates and Warren Buffet were asked what superpower would they want to have, in two different interviews, they both said the ability to read faster. While superpowers may not exist, Spritz can be the next best thing.


This app scans the web page you’re on and displays single words to you in a speed of your choosing. It takes some time to get used to, as our eyes are accustomed to scanning a page from left to right, but with a little bit of patience, you may have just discovered your first superpower! Test it out for yourself!


7. TED

TED, which stands for Technology, Education, and Design, requires no introduction. This global event attracts some of the finest leaders across the world, from Tony Robbins, to Bill Gates, to North Korean refugees. Real people, heartfelt stories, and eye-opening insights are shared on stage.

The best part is that you don’t need to pay $5,000 for a ticket to watch these talks — they’re all available for you to see online for free.


8. Scribd

Speaking of knowledge, if TED sparked your attention, then Scribd will be another popular choice.


Similar to Rype, Scribd is the Netflix for Ebooks. With a simple monthly payment, you can get read as many books as you would like in their library, where they have hundreds of thousands of books available.


9. CreativeLIVE

Want to learn from the best for free? CreativeLIVE is your answer.

CreativeLIVE has attracted world-class entrepreneurs, Pulitzer Prize winners, and New York Times Bestselling authors to teach topics like photography, business, marketing, and more.


10. Two Foods

As the saying goes, “we are what we eat.” Every day we make dozens of decisions on what we eat, and therefore what we become. We can decide to save money and eat healthier by waiting an additional 30 minutes to cook at home, or we can pass by the nearest McDonalds.


While some choices are easy when it comes to determining what’s healthier, some are hard. This is where Two Foods comes in.

This simple website allows you to type in the two different food you are debating, and they provide you with the nutritional information for each dish.


11. Wunderlist

It seems that as the day goes by, the bigger our to-do list seems to get. Sometimes we don’t have the time to write it down or organize it into different categories.


Wunderlist solves this problem. This free app allows you to create multiple to-do lists and categorize your different to-do’s. For example, I have one for my business, my personal, my upcoming book, my goals, and more.


12. Memrise

Memorizing things can be hard. Memrise provides an easy solution to make memorizing things fun through gamification.

For example, if you’re learning a new language, learning the most common words is key to picking up the language fast. You can use Memrise to quickly run through the words you want to learn and retain them through memorization techniques.


This can also apply to anything you want to remember, whether it’s the periodic table, parts of the human body, or countries.

13. Mint.com

One of the biggest tasks we tend to procrastinate on is our personal finances. Who’s with me?

Mint aims to solve this procrastination. By integrating our bank accounts into this website, it analyzes our spending, income, and budget in one place for us to see.

You can also set personal budgets for different categories — rent, travel, food, entertainment — and make sure you don’t go over it by tracking it all on Mint. My personal favorite is to be able to see all my spending for the month in a visual pie chart.


14. Kiva

So often, we think that we need to be amass large quantities of wealth before we give back. This couldn’t be further than the truth.


Most of us can spare a $25 loan to an entrepreneur who is making a difference across the world. And here’s the thing, it’s not a donation that you don’t get back, it’s a loan!

As described on Kiva’s website, here’s how it works:

  1. Choose a borrower
  2. Make a loan
  3. Get repaid
  4. Repeat!

kiva II large

15. Quora

Ever had a crazy question that you were curious to know the answer to?

Chances are, you can find the question and answer on Quora. Unlike most Q & A forums, Quora has managed to attract the best of the best, giving you real answers from real people.

For example, if you want to know what it’s like to work at Facebook, someone from Facebook can give you a direct answer. No BS, no fluff.

Quora has additional uses that go beyond than beating your curiousity. Entrepreneurs can use it to acquire potential customers, and anyone can use it to build an audience. What you do with the website is up to you!


16. Investopedia

Ask an average person on the street and they can tell you more about what’s happening with the Kardashians than they can tell you about their personal finances or what’s happening in the global markets.

Investopedia is the “Webster Dictionary for Investors.” Now you don’t need to be a stock investor to gain benefit from Investopedia. It can useful for general learning about finance, understanding how the markets work, and discovering how you can make or save more money at the end of the day.


17. Epicurious

This is the last app on our list, and perhaps the “sexiest” one. Ask someone in the streets on the top 10 skills they look for in a partner, and most will answer “the ability to cook.”


Epicurious helps you become sexier with simple yet diverse recipe ideas on healthy dishes and meals you can cook from your own kitchen. Give it a go!


Hopefully you’ve discovered something new on this list that you didn’t know before.

If you’ve gotten some value from this, please share this with your friends or family! It could change their lives.

The science community is keeping a wary eye on a Canadian research team’s claim of finding possible homes for life in outer space.

The researchers from Universite Laval in Quebec City say analysis of some unusual signals has helped them identify 234 potential systems that might be playing host to extra-terrestrial intelligence (ETI).

The theory has evolved over several years and took root when lead researcher Ermanno Borra published a paper in 2012 speculating on how residents of other galaxies may try to broadcast their existence to the rest of space.

He published a theory that such life forms could use lasers to make their home planet emit an unusual signal that would be noticed by anyone carefully observing the cosmos.

Now, Borra and graduate student Eric Trottier say they’ve identified 234 stars emitting that exact signal, adding they all appear to have characteristics that would enable them to help sustain life.

Fellow academics are intrigued enough by the research to study the findings more


but are currently treating the findings with skepticism and saying it’s too early to make definite claims.

Borra agrees, saying the latest findings – which have been published to a repository of scientific papers and are awaiting peer review – are far from conclusive.


“The kind of signal we found is in agreement with the ETI hypothesis, but right now it’s still a hypothesis that must be confirmed with further work,” Borra said in a telephone interview from Quebec City.

The signal at the heart of the theory involves lasers, which Borra said are a simple form of technology to produce and would be well within the capabilities of civilizations that are potentially much more advanced than humankind.

Borra theorized that sending flashes of light millionths of a second apart would be an easy feat that could produce a dramatic result – altering the unique light spectrum produced by an individual star.

Earth-bound scientists have already dedicated vast resources to charting the spectra of planets, stars and other bodies in various galaxies and collecting the information in central databases.

For their research, Borra and Trottier turned to the Slone Digital Sky Survey, a 16-year project that has purportedly mapped more than 30 per cent of the sky and catalogued

spectra for at least 2.5 million astronomical objects.

Borra said they compared the theoretical spectrum that would be produced by laser flashes to the survey results and found only 234 matches.


Borra said the stars in question all share spectral characteristics with the sun, which itself is too hot to support life forms. The stars he’s identified are therefore more likely to be the centres

of prospective stellar systems in which other life-sustaining planets could exist, he added.

“We intuitively expect that an ETI would bein a planet that turns around a star like the sun at about the same distance as the Earth from the Sun,” he said. “This is because this environment would be the best for life to exist. The proof comes from the fact that life exists on Earth.”

Borra said he accounted for the fact that the spectra might be caused by factors other than ETI, such as chemical makeup or calculation errors, but said the research suggests such factors are not at play.

Academics at the University of California, Berkeley, however, aren’t so quick to dismiss such causes.

The university’s Breakthrough Listen project has announced it will be studying the results more closely, but currently doesn’t place much stock in the findings as a sign of life beyond Earth.

Scientists dedicated to searching for extra-terrestrial intelligence have developed the Rio scale to assess the likelihood that anomalies are a sign of alien life. UC Berkeley currently give the Canadian findings a 0 or 1 on the Rio scale, classifying them as “insignificant.”


“The one in 10,000 objects with unusual spectra seen by Borra and Trottier are certainly worthy of additional study,” the university said in a statement. “However, extraordinary claims require extraordinary evidence. It is too early to unequivocally attribute these purported signals to the activities of extraterrestrial civilizations.”

Borra said the Berkeley researchers will try to reproduce the results with their own telescopes, adding he welcomes the additional scrutiny and potential confirmation from outside sources.

“I do not know myself what this really is,” he said. “More work has to be done to confirm it.
