17 Surprising Reasons You’re Stressed Out

April 13, 2015 / / 0 Comments





Excerpt from huffingtonpost.com
By Amanda MacMillan


You're probably all too aware of the major sources of stress in your life -- money, your terrible commute, the construction workers who start jackhammering at 5 a.m. But stress and anxiety don't have to just come from obvious or even negative sources. "There are plenty of chronic strains and low-grade challenges that don't necessarily overwhelm you in the moment, but almost take more of a toll in the long run," says Scott Schieman, Ph.D., professor of sociology at the University of Toronto. These are some of unexpected reasons why you might feel anxious or agitated. By recognizing them for what they are, says Schieman, you can better prepare to cope.

1. Your Significant Other
Even if you have a blissfully happy relationship with your live-in partner or spouse, you're both bound to do things that get on each other's nerves. "Early in the relationship, it's usually about space and habits -- like whether you squeeze the toothpaste from the middle or the bottom of the tube," says Ken Yeager, Ph.D., associate professor of psychiatry at the Ohio State University Wexner Medical Center. "Later on, you might clash over parenting style or financial issues, and finding a unified front to face these issues together." So what's the key to surviving and thriving in your life together? Finding balance, says Yeager: spending the right amount of time together (not too much and not too little), making compromises, keeping communication open and honest, and remembering to acknowledge what you love about each other on a daily basis.

2. Everyday Annoyances
We're told not to sweat the small stuff, but sometimes it's the little things that have the biggest impact on our mood: the never-ending phone calls with your insurance company, the rude cashier at the grocery store, the 20 minutes you lose looking for a parking space. "We let these things bother us because they trigger unconscious fears," says Yeager -- fears of being seen as irresponsible, of being bullied or embarrassed, or of being late all the time, for example. "Sometimes you need to take a step back and realize that you're doing the best you can given the circumstances." 

3. Other People's Stress
Stress is contagious, according to a 2014 German study: In a series of experiments, most participants who simply observed others completing a stressful task experienced an increase themselves in production of the stress hormone cortisol -- a phenomenon known as empathic stress. You can also experience stress when someone you know is affected by a traumatic event, like a car crash or a chronic illness. "You start to worry, 'Oh my gosh, could that happen to me?'," says Yeager. "We tend not to think about these things until they hit close to home."

4. Social Media social media
It may seem like Facebook is the only way you keep up with the friends you don't see regularly -- which, during particularly busy times, can be just about all of them. The social network also has a downside, according to a 2015 study from the Pew Research Center: It can make you aware of stressful situations in your friends' lives, which in turn can add more stress to your life. The Pew report didn't find that social media users, overall, had higher levels of stress, but previous studies have suggested that frequent social-media use can be associated with negative body image and prolonged breakup pain.

5. Distraction
A distraction can be a good thing then when it takes your mind off of a stressful situation or difficult decision, like when you take a break from work to meet a friend for lunch. But it works the other way, as well: When you're so busy thinking about something else that you can't enjoy what's going on around you, that kind of distraction can be a recipe for stress. Practicing mindfulness gives you brain the refresh it needs, says Richard Lenox, director of the Student Counseling Center at Texas Tech University. Paying full attention to your surroundings when you're walking and driving can help, he adds. "Stress and anxiety tend to melt away when our mind is focused on the present." 

6. Your Childhood
Traumatic events that happened when you were a kid can continue to affect your stress levels and overall health into adulthood. A 2014 University of Wisconsin-Madison study found that these childhood experiences may actually change parts of the brain responsible for processing stress and emotion. The way you were raised can also have a lasting impact on your everyday angst, suggests a 2014 Johns Hopkins University study. Researchers found that children of parents with social anxiety disorders are more likely to develop "trickle-down anxiety" -- not simply because of their genes, but because of their parents' behaviors toward them such as a lack of warmth and emotion, or high levels of criticism and doubt.

7. Tea And Chocolate
You probably know to take it easy on the coffee when you're already feeling on edge. "Caffeine is always going to make stress worse," says Yeager. But you may not think as much about drinking several cups of tea at once, or chowing down on a bar of dark chocolate -- both of which can contain nearly as much caffeine as a cup of joe. "Chocolate is a huge caffeine source," says Yeager. "I know people who don't drink coffee but they'll eat six little candy bars in a two-hour period because they want the same kind of jolt." Too much caffeine, in any form, can cause problems with sleep, digestion, and irritability. 

8. Your Expectations woman trail running
When things don't go the way you've planned, do you tend to get upset and act defensively, or do you roll with the punches and set off on a new plan? If it's the former, you could be contributing to a mindset of pessimism and victimization that will slowly wear you down, even when things may not be as bad as they seem. "Your level of serenity is inversely proportionate to your expectations," says Yeager. That doesn't mean you shouldn't set ambitious goals for yourself or settle for less than what you want, of course, but being realistic about what's truly possible is important, as well.

9. Your Reaction To Stress
If you tend to deal with stressful situations by working long hours, skipping your workouts, and bingeing on junk food, we've got some bad news: You're only making it worse. "We know that physical activity and healthy foods will help your body better deal with stress, and yet we often avoid them when we need them the most," says Yeager. "People really need to think about this downward spiral we get into and work harder to counteract it."

10. Multitasking
Think you're being super efficient by tackling four tasks at once? Chances are you're not -- and it's only decreasing your productivity while increasing your stress. A 2012 University of Irvine study, for example, found that people who responded to emails all day long while also trying to get their work done experienced more heart-rate variability (an indicator of mental stress) than those who waited to respond to all of their emails at one time. Focusing on one task at a time can ensure that you're doing that job to the best of your abilities and getting the most out of it, so you won't have to worry about or go back and fix it later, says Schieman. And don't worry: You'll have enough time to do it all. In fact, you may discover you have more time than you thought.

11. Your Favorite Sport
Watching a tight game of college hoops can stress you out -- even if your alma mater wins. "The body doesn't distinguish between 'bad' stress from life or work and 'good' stress caused by game-day excitement," says Jody Gilchrist, a nurse practitioner at the University of Alabama at Birmingham’s Heart and Vascular Clinic. Watching sports can even trigger the body's sympathetic nervous system, releasing adrenaline and reducing blood flow to the heart. Those temporary consequences aren't usually anything to be concerned about, but over time, chronic stress can lead to high blood pressure and increased disease risk. And, of course, it doesn't help if you're adding alcohol and binge-eating to a situation that's already stressful on your body. You may not be able to control the outcome of the game, says Gilchrist, but you can limit its effects on your own body. 

12. Digital Devices laptop in bed
Whether you're using it for work or play, technology may play a large role in your mental health, says Yeager. Using computers or e-readers too close to bedtime could lead to sleep problems, he says, and spending too much time virtually socializing can make real-life interactions seem extra stressful. (Plus, texting doesn't trigger the same feel-good hormones as face-to-face talk does.) Then there's the dreaded "work creep," says Schieman, when smartphones allow employees to be tethered to their jobs, even during off-hours. "People say they're only going to check email for an hour while they're on vacation, but the problem with email is that they're filled with responsibilities, new tasks, and dilemmas that are going to be hard to compartmentalize and put out of your head once that hour is up."

13. Your (Good) Health
While it may not be as stressful as having a chronic illness or getting bad news at the doctor's office, even people in the best shape of their lives worry about their bodies, their diets, and their fitness levels. In fact, people who take healthy living to an extreme may experience some rather unhealthy side effects. People who follow low-carb diets, for example, are more likely to report being sad or stressed out, while those on any kind of restrictive meal plan may feel more tired than usual. And it's not unheard of for someone to become obsessed with healthy eating (known as orthorexia) or working out (gymorexia). Like any form of perfectionism, these problems can be stressful at best, and extremely dangerous at worst.

14. Housework
Does folding laundry help you feel calm, or does it make your blood boil? If you're in a living situation where you feel you're responsible for an unfair share of work, even chores you once enjoyed may start to feel like torture. "Dividing up housework and parenting responsibilities can be tricky, especially if both partners work outside the home," says Schieman. "And whether you define that division of labor as equal or unequal can really change your attitude toward it."

15. Uncertainty
Stress can be defined as any perceived or actual threat, says Yeager, so any type of doubt that's looming over you can contribute to your anxiety levels on a daily basis. "When you know something could change at any minute, you always have your guard up and it's hard to just relax and enjoy anything." Financial uncertainty may be the most obvious stressor -- not being sure if you'll keep your job during a round of layoffs, or not knowing how you'll pay your credit card bill. Insecurities in other areas of life, like your relationship or your housing status, can eat away at you too.

16. Your Pet bulldog puppy
No matter how much you love your furry friends, there's no question that they add extra responsibility to your already full plate. Even healthy animals need to be fed, exercised, cleaned up after, and given plenty of attention on a regular basis -- and unhealthy ones can be a whole other story. "Pets can be the most positive source of unconditional love, but at the same time they require an extreme amount of energy," says Yeager. People also tend to underestimate the stress they'll experience when they lose a pet. "I've had people in my office tell me they cried more when their dog died than when their parent died. It's a very emotional connection."

17. Your Education
Having a college degree boosts your odds of landing a well-paying job, so although you're less likely to suffer from money-related anxiety, your education can bring on other types of stress, according to a 2014 study by Schieman and his University of Toronto colleagues. His research found that highly educated people were more likely to be stressed out thanks to job pressures, being overworked, and conflicts between work and family. "Higher levels of authority come with a lot more interpersonal baggage, such as supervising people or deciding whether they get promotions," says Schieman. "With that type of responsibility, you start to take things like incompetency and people not doing their jobs more personally, and it bothers you more."

New research shows billions of habitable planets exist in our galaxy

March 18, 2015 / / 0 Comments



CGI of how the Milky Way galaxy may appear from deep space


Excerpt from thespacereporter.com


Analysis of data collected by NASA’s Kepler space telescope has led researchers at the Australian National University and the Niels Bohr Institute to conclude that Earth is only one of billions of potentially life-sustaining planets in our galaxy.

In order for a planet to sustain life, it must orbit its star at just the right distance to provide sufficient light and warmth to maintain liquid water without too much radiation. This perfect orbital distance is considered to be the habitable zone.

According to a Weather Channel report, there are an average of two planets per star in the Milky Way Galaxy orbiting within their habitable zones. That brings the total number of planets with the potential for holding liquid water to 100 billion.

Scientists assume that water would be an essential ingredient for life to evolve on other planets, but it is not a certainty.

“If you have liquid water, then you should have better conditions for life, we think,” said Steffen Jacobsen of Niels Bohr. “Of course, we don’t know this yet. We can’t say for certain.”

To reach their conclusion, the researchers studied 151 planetary systems and focused on those with four or more planets. They used a concept called the Titus-Bode law to calculate where unseen planets might be located in a system based on the placements of other planets around the star. The Titus-Bode law suggested the existence of Uranus before it was actually seen.

The data will require further analysis and the sky will require further searching to yield a more accurate number of potentially life-harboring planets.
“Some of these planets are so small the Kepler team will probably have missed them in the first attempt because the signals we get are so weak. They may be hidden in the noise,” Jacobsen said.

The initial analysis, however, is extremely promising in the possibility of finding habitable planets. “Our research indicates that there are a lot of planets in the habitable zone and we know there are a lot of stars like the one we’re looking at. We know that means we’re going to have many billions of planets in the habitable zone,” said Jacobsen, who considers that “very good news for the search for life.”

Habitable’ Super-Earth Might Exist After All

March 9, 2015 / / 0 Comments


Artist's impression of Gliese 581d, a controversial exoplanet that may exist only 20 light-years from Earth.



Excerpt from news.discovery.com

Despite having discovered nearly 2,000 alien worlds beyond our solar system, the profound search for exoplanets — a quest focused on finding a true Earth analog — is still in its infancy. It is therefore not surprising that some exoplanet discoveries aren’t discoveries at all; they are in fact just noise in astronomical data sets.

But when disproving the existence of extrasolar planets that have some characteristics similar to Earth, we need to take more care during the analyses of these data, argue astronomers from Queen Mary, University of London and the University of Hertfordshire.

In a paper published by the journal Science last week, the researchers focus on the first exoplanet discovered to orbit a nearby star within its habitable zone.

Revealed in 2009, Gliese 581d hit the headlines as a “super-Earth” that had the potential to support liquid water on its possibly rocky surface. With a mass of around 7 times that of Earth, Gliese 581d would be twice as big with a surface gravity around twice that of Earth. Though extreme, it’s not such a stretch of the imagination that such a world, if it is proven to possess an atmosphere and liquid ocean, that life could take hold.

And the hunt for life-giving alien worlds is, of course, the central motivation for exoplanetary studies.

But the exoplanet signal has been called into doubt.
Gliese 581d’s star, Gliese 581, is a small red dwarf around 20 light-years away. Red dwarfs are known to be tempestuous little stars, often generating violent flaring outbursts and peppered in dark features called starspots. To detect the exoplanet, astronomers measured the very slight frequency shift (Doppler shift) of light from the star — as the world orbits, it exerts a tiny gravitational “tug”, causing the star to wobble. When this periodic wobble is detected, through an astronomical technique known as the “radial velocity method,” a planet may be revealed.

Last year, however, in a publication headed by astronomers at The Pennsylvania State University, astronomers pointed to the star’s activity as an interfering factor that may have imitated the signal from an orbiting planet when in fact, it was just noisy data.

But this conclusion was premature, argues Guillem Anglada-Escudé, of Queen Mary, saying that “one needs to be more careful with these kind of claims.”

“The existence, or not, of GJ 581d is significant because it was the first Earth-like planet discovered in the ‘Goldilocks’-zone around another star and it is a benchmark case for the Doppler technique,” said Anglada-Escudé in a university press release. “There are always discussions among scientists about the ways we interpret data but I’m confident that GJ 581d has been in orbit around Gliese 581 all along. In any case, the strength of their statement was way too strong. If the way to treat the data had been right, then some planet search projects at several ground-based observatories would need to be significantly revised as they are all aiming to detect even smaller planets.”

The upshot is that this new paper challenges the statistical technique used in 2014 to account for the signal being stellar noise — focusing around the presence of starspots in Gliese 581′s photosphere.

Gliese 581d isn’t the only possible exoplanet that exists around that star — controversy has also been created by another, potentially habitable exoplanet called Gliese 581g. Also originally detected through the wobble of the star, this 3-4 Earth mass world was found to also be in orbit within the habitable zone. But its existence has been the focus of several studies supporting and discounting its presence. Gliese 581 is also home to 3 other confirmed exoplanets, Gliese 581e, b and c.

Currently, observational data suggests Gliese 581g was just noise, but as the continuing debate about Gliese 581d is proving, this is one controversy that will likely keep on rumbling in the scientific journals for some time.

Could Saturn’s moon Titan host an alternate type of life?

March 5, 2015 / / 0 Comments


Titan


Excerpt from mashable.com

In a world first, chemical engineers have taken a different look at a question astronomers and biologists have been pondering for decades: Does Saturn moon Titan host life?

Of course, Titan is way too hostile for life as we know it to eke out an existence — it is a frigid world awash with liquid methane and ethane and a noxious atmosphere devoid of any liquid water. But say if there is a different kind of biology, a life as we don't know it, thriving on the organic chemistry that is abundant on Titan's surface?

Normally, astrobiologists combine what we know about Earth's biosphere and astronomers zoom in on other stars containing exoplanets in the hope that some of those alien world have some similarities to Earth. By looking for small rocky exoplanets orbiting inside their star's habitable zones, we are basically looking for a "second Earth" where liquid water is at least possible. Where there's liquid water on Earth, there's inevitably life, so scientists seeking out alien life 'follow the water' in the hope of finding life with a similar terrestrial template on other planets.

Titan, however, does not fall into this category, it is about as un-Earth-like as you can get. So, chemical molecular dynamics expert Paulette Clancy and James Stevenson, a graduate student in chemical engineering, from Cornell University, Ithaca, New York, have looked at Titan in a different light and created a theoretical model of a methane-based, oxygen-free life form that could thrive in that environment.

There is no known template for this kind of life on Earth, but the researchers have studied what chemicals are in abundance on Titan and worked out how a very different kind of life could be sparked.

As a collaborator on the NASA/ESA Cassini-Huygens mission, Lunine, professor in the Physical Sciences in the College of Arts and Sciences’ Department of Astronomy, has been fascinated with the possibility of methane-based life existing on Titan for some time, so he joined forces with Clancy and Stevenson to see what this hypothetical life form might look like.

In their research published in the journal Science Advances on Feb. 27, Clancy and Stevenson focused on building a cell membrane "composed of small organic nitrogen compounds and capable of functioning in liquid methane temperatures of 292 degrees below zero (Fahrenheit; or 94 Kelvin)," writes a Cornell press release. On Earth, water-based molecules form phospholipid bilayer membranes that give cells structure, housing organic materials inside while remaining permeable. On Titan, liquid water isn't available to build these cell membranes.

"We're not biologists, and we're not astronomers, but we had the right tools," said Clancy, lead researcher of the study. "Perhaps it helped, because we didn't come in with any preconceptions about what should be in a membrane and what shouldn't. We just worked with the compounds that we knew were there and asked, 'If this was your palette, what can you make out of that?'"

The researchers were able to model the ideal cell that can do all the things that life can do (i.e. support metabolism and reproduction), but constructed it from nitrogen, carbon and hydrogen-based molecules that are known to exist in Titan's liquid methane seas. This chemical configuration gives this theoretical alien cell stability and flexibility in a similar manner to Earth life cells.
"The engineers named their theorized cell membrane an 'azotosome,' 'azote' being the French word for nitrogen. 'Liposome' comes from the Greek 'lipos' and 'soma' to mean 'lipid body;' by analogy, 'azotosome' means 'nitrogen body.'" — Cornell
"Ours is the first concrete blueprint of life not as we know it," said lead author Stevenson, who also said that he was inspired, in part, by Isaac Asimov, who wrote the 1962 essay "Not as We Know It" about non-water-based life.

Having identified a possible type of cell membrane chemistry that functions in the Titan environment as a cell on Earth might, the next step is to model how such a hypothetical type of biology would function on Titan. In the long run, we might also be able to model what kinds of observable indicators we should look for that might reveal that alien biology's presence.

That way, should a mission be eventually sent to Titan's seas, sampling the chemical compounds in the soup of organics may reveal a biology of a very alien nature.
Scientists have been trying to know if life could exist on Titan, the largest moon of Saturn. According to scientists, there are possibilities that life could survive amidst methane-based lakes of Titan. After conducting many studies, they have found signs of life on Titan, but the scientists also said that life will not be like life on earth.
As per some scientific reports, Titan is the only object other than earth which has clear evidence of stable bodies of surface liquid. Like earth, the moon has mountains, islands, lakes and storms, but it doesn’t have oxygen, which is a major element to support life. It means that only oxygen-free and methane-based can exist on Titan.
According to lead researcher Paulette Clancy, “We didn’t come in with any preconceptions about what should be in a membrane and what shouldn’t. We just worked with the compounds that, we knew were there and asked, ‘If this was your palette, what can you make out of that”.
Clancy said although they are not biologists or astronomers, they had the right tools to find life on Saturn’s largest moon. Adding to that, the researchers didn’t know what should be in a membrane and what should be not. They worked with compounds and found that life can exist on Titan, but would be very different from earth’s life, Clancy added.
According to reports, the researchers had used a molecular dynamics method to know about Titan. They screened for suitable candidate compounds from methane for self-assembly into membrane-like structures. As per the researchers, the most promising compound they discovered was an acrylonitrile azotosome, which is present in the atmosphere of Titan.
As per the researchers, acrylonitrile has shown good stability and flexibility similar to that of phospholipid membranes on Earth. It means that the Saturn largest has atmosphere and conditions to support life in a different way than earth.

Do we really want to know if we’re not alone in the universe?

March 4, 2015 / / 0 Comments



Frank Drake, the founder of Search for Extraterrestrial Intelligence (SETI), at his home in Aptos, Calif. (Ramin Rahimian for The Washington Post)


Excerpt from washingtonpost.com

It was near Green Bank, W.Va., in 1960 that a young radio astronomer named Frank Drake conducted the first extensive search for alien civilizations in deep space. He aimed the 85-foot dish of a radio telescope at two nearby, sun-like stars, tuning to a frequency he thought an alien civilization might use for interstellar communication.

But the stars had nothing to say.

So began SETI, the Search for Extraterrestrial Intelligence, a form of astronomical inquiry that has captured the imaginations of people around the planet but has so far failed to detect a single “hello.” Pick your explanation: They’re not there; they’re too far away; they’re insular and aloof; they’re zoned out on computer games; they’re watching us in mild bemusement and wondering when we’ll grow up.

Now some SETI researchers are pushing a more aggressive agenda: Instead of just listening, we would transmit messages, targeting newly discovered planets orbiting distant stars. Through “active SETI,” we’d boldly announce our presence and try to get the conversation started.

Naturally, this is controversial, because of . . . well, the Klingons. The bad aliens.

 NASA discovers first Earth-size planet in habitable zone of another star

"NASA's Kepler Space Telescope has discovered the first validated Earth-size planet orbiting in the habitable zone of a distant star, an area where liquid water might exist on its surface. The planet, Kepler-186f, is ten percent larger in size than Earth and orbits its parent star, Kepler-186, every 130 days. The star, located about 500 light-years from Earth, is classified as an M1 dwarf and is half the size and mass of our sun." (NASA Ames Research Center)
“ETI’s reaction to a message from Earth cannot presently be known,” states a petition signed by 28 scientists, researchers and thought leaders, among them SpaceX founder Elon Musk. “We know nothing of ETI’s intentions and capabilities, and it is impossible to predict whether ETI will be benign or hostile.”

This objection is moot, however, according to the proponents of active SETI. They argue that even if there are unfriendlies out there, they already know about us. That’s because “I Love Lucy” and other TV and radio broadcasts are radiating from Earth at the speed of light. Aliens with advanced instruments could also detect our navigational radar beacons and would see that we’ve illuminated our cities.

“We have already sent signals into space that will alert the aliens to our presence with the transmissions and street lighting of the last 70 years,” Seth Shostak, an astronomer at the SETI Institute in California and a supporter of the more aggressive approach, has written. “These emissions cannot be recalled.”

That’s true only to a point, say the critics of active SETI. They argue that unintentional planetary leakage, such as “I Love Lucy,” is omnidirectional and faint, and much harder to detect than an intentional, narrowly focused signal transmitted at a known planet.

NASA and ESA telescopes trace ultra-strong winds blowing from black holes

February 21, 2015 / / 0 Comments


 



Excerpt from thespacereporter.com

According to a NASA statement, telescopes have revealed for the first time that powerful winds emanate from black holes in all directions. These winds are so tremendous that they can actually work to hamper the formation of new stars in the host galaxy.
The two telescopes that were employed by the agency, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s XMM-Newton, focused on PDS 456, a quasar, an extremely bright type of black hole, over 2 billion light-years away. The results were then analyzed by a team led by Emanuele Nardini of Keele University in the UK.
The two telescopes studied the quasar PDS 456 at five different times throughout 2013 and 2014. By combining low-energy X-ray observations from XMM-Newton with high-energy X-ray observations from NuSTAR, Nardini and team were able to trace iron dispersed by the quasar’s winds. These data demonstrated that the winds blow outwards from the black hole in a spherical front.
Having ascertained the structure of the quasar winds, the team was then able to calculate the strength of the winds. So strong are the quasar winds that they push huge quantities of matter before them, dispersing it outwards through the host galaxy and preventing it from eventually coalescing to generate new stars. In an earlier period of the universe’s history, about 10 billion years ago, supermassive black holes were more abundant and their terrible winds probably had a hand in shaping the current shapes of galaxies.
“For an astronomer, studying PDS 456 is like a paleontologist being given a living dinosaur to study,” said co-author Daniel Stern of NASA’s Jet Propulsion Laboratory. “We are able to investigate the physics of these important systems with a level of detail not possible for those found at more typical distances, during the ‘Age of Quasars.’”
The new findings have been published in the journal Science.
