NASA's flying obervatory 'SOFIA' reveals nearby planetary system is remarkably similar to our own


The Stratospheric Observatory for Infrared Astronomy, or SOFIA, studying a nearby planetary system has confirmed that it has an architecture remarkably similar to that of our solar system.
NASA's SOFIA, the world's largest airborne astronomical observatory, recently completed a detailed study of this nearby planetary system.
Located 10.5 light-years away in the southern hemisphere of the constellation Eridanus, the star Epsilon Eridani, eps Eri for short, is the closest planetary system around a star similar to the early sun.
It is a prime location to research how planets form around stars like our sun, and is also the storied location of the Babylon 5 space station in the science fictional television series of the same name, a a NASA release published on its official website.
Previous studies indicate that eps Eri has a debris disk - that can be broad, continuous disks or concentrated into belts of debris, similar to our solar system’s asteroid belt and the Kuiper Belt.
Debris disk is the name astronomers give to leftover material still orbiting a star after planetary construction has completed. The debris can take the form of gas and dust, as well as small rocky and icy bodies.
Furthermore, careful measurements of the motion of eps Eri indicates that a planet with nearly the same mass as Jupiter circles the star at a distance comparable to Jupiter’s distance from the Sun, according to the report.
Using new SOFIA images, Kate Su of the University of Arizona and her research team were able to distinguish between two theoretical models of the location of warm debris, such as dust and gas, in the eps Eri system. These models were based on prior data obtained with NASA’s Spitzer space telescope.
“One model indicates that warm material is in two narrow rings of debris, which would correspond respectively to the positions of the asteroid belt and the orbit of Uranus in our solar system. Using this model, theorists indicate that the largest planet in a planetary system might normally be associated with an adjacent debris belt, the report added.”
“The other model attributes the warm material to dust originating in the outer Kuiper-Belt-like zone and filling in a disk of debris toward the central star. In this model, the warm material is in a broad disk, and is not concentrated into asteroid belt-like rings nor is it associated with any planets in the inner region.”
Su and her team ascertained that the warm material around eps Eri is in fact arranged like the first model suggests; it is in at least one narrow belt rather than in a broad continuous disk.
This study was published in the Astronomical Journal on April 25, 2017.

Pine Nuts: Are Their Health Benefits Worth The Cost?

Tasty, buttery pine nuts are considered one of the fanciest of all nuts. They are actually the seeds of pine trees and not really nuts. They are found in the pine cones but only 18 types of pine trees create pine nuts that are large enough to eat. Like most nuts, they are packed full of nutrition and health benefits.
Health Benefits
In numerous studies, the consumption of nuts was found to lower waist circumference, blood pressure, insulin resistance and increase high cholesterol.
Healthier Weight
Those who eat nuts regularly have been found to maintain a healthy weight, according to research. The thought is that those eating nuts regularly have a considerably healthy diet because they are getting more fiber, vitamin E, calcium, magnesium and potassium, according to statistics.
Bad Cholesterol Lowered
Mixed nuts (walnuts, peanuts and pine nuts), when included in a healthy diet for six weeks, showed an improvement in cholesterol levels.
Suppresses Appetite
The fatty acids in pine nuts help release an appetite-suppressing hormone (cholecystokinin). When women in a study consumed fatty acid (pinolenic acid from the pine nut) before breakfast it was found to lower the amount of food eaten throughout the day by 37 percent. Pine nut oil was found to help overweight, post-menopausal women suppress their appetite in this study.
Decreases Heart Disease Risk
There was a decrease in cardiovascular disease in participants that ate one-quarter ounce of nuts per day in a 1999-2004 study
Please Note: As with all nuts, they have been known to cause allergic reactions. There is a rare allergic reaction to pine nuts known as Pine Mouth Syndrome which can last a few weeks but it is not dangerous. This causes a bitter or metallic taste after eating pine nuts.
  
Growing and Harvesting Pine Nuts is An Expensive Process
There are about 18 pine trees that produce nuts worthy of harvesting. These trees are found in Europe, Russia, Mongolia, Eastern Siberia, North Korea and North America. There are eight varieties that grow in cold climates such as Canada.
It can take at least 10 years to get pine nuts from a tree; first, it takes between 6-8 years for the tree to mature fully and then 2-3 more years to develop the pine nuts. They ripen in late summer or early fall.
Next is the drying process: they are placed in a burlap bag and exposed to heat to dry out the cone for about 20 days. The outer shell must be removed, the cones are broken apart and the seeds are taken out. This time-consuming process makes it an expensive nut. Learn more reasons why pine nuts are so expensive.
Nutrient Dense
One ounce serving (165 pine nuts) contains a wide variety of nutrients (potassium, protein, iron, magnesium, phosphorus, zinc, thiamin, niacin, vitamin E, vitamin K and more) Go here for more nutrition details.
History
Pine nuts have been consumed since Stone Age times; remains have been found in caves in southern France. The pine nut tree has been cultivated since about 4000 BCE according to Archaeologists.
They have been harvested for over 8,000 years. There is proof of them being found in excavations at Gatecliff Shelter, Nevada, 6,000 years BCE. 
How to Select
Shelled nuts are best in air-tight plastic bags in the stores. Make sure they are fresh, have not lost their light color and are not brown.
How to Store
Their high-fat content makes it important to store them in the refrigerator for 1 – 3 months or kept in an airtight container or in the freezer for up to 9 months.  At room temperature, they will only last for a week before going rancid.
Tips for eating or cooking
They are delicious raw, but you can also eat them roasted, adding a sweet nutty flavor and crunch to vegetable dishes and salads. And of course, there is delicious pesto.

5 Non-Food Uses for Sugar

Refined sugars aren’t so hot for our health, but there are some household uses for the sweet stuff that might surprise you!
You may not put sugar in your tea these days, but it’s actually an effective degreaser, stain remover, and craft supply. From cleaning uses to DIY projects, there are lots of ways to use sugar around the house without eating a single granule.

5 NON-FOOD USES FOR SUGAR

1. CLEAN YOUR HANDS

Do you have greasy hands from cooking or working on your car? Put about a teaspoon of sugar into the palm of your hand before washing with soap as usual. The sugar helps cut the grease and scrub it away. 

2. MAKE SUGAR SCRUB

Sugar is a gentle exfoliator that’s perfect for sloughing away dead skin. Combined with a little bit of oil, you’ve got yourself a skin scrub that exfoliates, moisturizes, and costs a whole lot less than commercial sugar scrubs. Even better? You can scent your homemade sugar scrub with essential oils rather than the chemical fragrance that you find in its store-bought counterpart.

3. SUGAR SCULPTURES

The tutorial linked above is for making Mexican sugar skulls, but you can use that same technique with different molds to create any shapes you like. Sugar sculptures use all food-based ingredients, but they’re not intended to be eaten. In the link above, she mentions that she made the skulls for her tutorial a full year before she got around to decorating them!

4. CLEAN THE COFFEE GRINDER

Coffee beans contain natural oils, and sugar helps cut that grease while the grains scour your grinder clean. Like one commenter suggests, you can also use sugar to clean it out, then use the sugar to sweeten your coffee, if you’re so inclined. If not, just toss it into the compost bin.

5. DIY STAIN REMOVER

Create a paste with water, white vinegar, and sugar to pre-treat stained clothing before washing. Let the paste sit for 10-20 minutes, rinse, then wash your garment in cold water. Before you stick it in the dryer, make sure that the stain is gone. If not, you’ll want to treat and wash in cold again. If you put the stained fabric into the dryer, the heat can set the stain.

8 Delicious Ways to Eat Less Salt

Most Americans eat far more than the recommended limit, but cutting back on salty food can be tough, especially if your palate has adjusted to a high-salt diet. Here are some ways to reduce the salt in your diet without sacrificing flavor.
Here in the U.S., we chronically oversalt our food. Whether we’re eating salty, processed foods or reaching for that salt shaker too often, all of that excess salt adds up. Too much salt makes us eat more and drink less water, and it puts us at risk for heart disease.
The recommended limit for salt is between 1500 mg and 2300 mg per day: between 3/4 and one teaspoon. The average American eats 3400 mg of salt per day, more than one-and-a-half times the highest recommended limit.
I cut way back on salt when I was pregnant to help ease pregnancy-related swelling. It was not easy at first, but over time I came up with a strategy and some tricks to make the transition more smooth. These are the things that helped me learn how to eat less salt.

1. Cut back gradually.

If you’ve been eating a lot of salt for a long period of time, your palate has likely adjusted. If you just cut the salt out of your food right away, it’s going to seem flavorless. Instead, try tapering the amount of salt you’re eating over a week or two until you reach your goals. 

2. Hide the salt shaker.

This is a great first step when you’re tapering. Try not salting your food once it’s prepared. Almost all recipes already call for salt in some form, and shaking on even more salt isn’t doing us any favors. 
If you really don’t feel ready to do this right away, try limiting how much salt you shake on. If you usually do three shakes, see if you can get by with two for a few days, then one, then get that shaker out of there.

3. Choose low-sodium soy sauce.

I don’t know about you, but I tend to use soy sauce more than table salt to add sodium to my dishes. We don’t always think of soy sauce as salt, but if you’re trying to get down to 2300 mg or less per day, soy sauce can be a big contributor.
Low-sodium soy sauce has about one third less sodium than traditional. Just make sure you’re not adding more low-sodium soy sauce to your food. Like the salt shaker, don’t reach for the soy sauce after you food is plated.

4. Cut back on processed foods.

Processed food tends to be high in salt for two reasons. First of all, salt is a cheap way to make things taste delicious. Salt is also a good preservative. Cutting out all packaged foods isn’t realistic for everyone, though, and that’s okay!
When you do buy packaged food, look for ones marked low-sodium or reduce sodium. And don’t let front-of-package labeling fool you. Turn that bag of chips over and read the nutrition label to see what percentage of your daily sodium is in that bag.

5. Cook at home.

You don’t have to give up all take-out forever when you cut back on salt, but cooking at home definitely helps you control how much salt is on your food. Restaurants love salt, because salt makes food taste good without adding much cost to a dish. The good news is, you can make home-cooked meals taste good with less salt!

6. Reach for the herbs.

Salt enhances your food’s flavor, but you can also add flavor by adding more fresh or dried herbs to your dishes. Try upping the herbs and spices in your favorite recipes while cutting back on the added salt. You may find that you didn’t need that added sodium in the first place!

7. Drop some acid. 

Into your bowl! A squeeze of lemon juice or dash of vinegar was one of my favorite ways to compensate for the “missing” salt when I started cutting back. Acidic foods like citrus add a similar bite to your dishes, no sodium needed.

8. Choose low- or no-sodium broth.

Broth is a major culprit when it comes to added salt, but it doesn’t have to be! One of my favorite tricks for keeping the flavor while cutting the salt in my soups was to use no-sodium broth cubes, but use twice as many cubes as the package called for.
You can also use broth to add flavor to your grains, beans and stews. Almost any time you see water in a savory recipe, you can sub no-sodium broth for a flavor boost. This is really just a cheater’s way to add more herbs without having to chop more herbs.

The Hidden Food Ingredient Linked to Pain and Inflammation

There’s a food additive so ubiquitous in the food industry it is found in most packaged foods, restaurant sauces and even many foods that have been “certified organic.” That ingredient is carrageenan. While the additive starts out harmless enough (it comes from the seaweed known as Irish moss) it is then processed to extract the ingredient known as carrageenan, which acts as a thickener or emulsifier for many prepared foods.
Like most people, I originally thought that carrageenan was a harmless extract from seaweed, so I didn’t give it much consideration. Then I heard that researchers were giving animals carrageenan to induce pain and inflammation as a way to prepare the animals for scientific studies exploring anti-pain drugs. That was the first I’d heard of carrageenan being used for harm. So I began to investigate.
Dr. Joanne Tobacman has conducted many studies on the effects of carrageenan consumption, including one in the Journal of Diabetes Research. After eating carrageenan for only six days, animals fed carrageenan developed glucose intolerance, an umbrella term used to describe impaired metabolism involving excessively high blood sugar levels. Dr. Tobacman found that the food additive caused blood sugar levels to skyrocket, indicating that it may lead to the development of diabetes. She indicates that carrageenan used in animals’ diets so commonly cause diabetes that the additive could be used for mouse models of the study of diabetes. 
She also found that carrageenan causes intestinal and systemic inflammation in animal studies. Considering that inflammation is a well-established factor in most chronic disease, including: heart disease, diabetes, cancer, arthritis, pain disorders and many others, any food additive in common use is a serious concern. Dr. Tobacman also indicates that the amount of carrageenan found in most peoples’ diets is sufficient to cause inflammation.
Sources of Carrageenan
Carrageenan is found in common foods, including:
infant formula
ice cream
cream
butter
soy milk
almond milk
rice milk
cottage cheese
sour cream
yogurt
coffee creamers
vegan cheese alternatives
egg nog
protein supplements
aloe vera gel
deli meats
juices
puddings
pizzas
chocolate bars
coffee beverages
many packaged foods
Additionally, some supplements, particularly those involving gel caps, commonly contain carrageenan. And, most grocery store rotisserie chickens typically contain the additive.
The Cornucopia Institute has compiled a comprehensive list of organic foods that contain carrageenan, since the ingredient is legally allowed in foods bearing the label “organic” or “certified organic.”

13 Wonderful Benefits Of Grapefruit

The health benefits of grapefruits are wide-ranging and nearly unmatched by any other fruit. A glass of chilled grapefruit juice, especially in winter, helps seriously boost your levels of vitamin C, which gives grapefruits a high place amongst various citrus fruits. It’s packed with the benefits derived from various nutrients and vitamins, including potassium and lycopene. Along with these, it also contains calciumsugar and phosphorous. In terms of its culinary value, it is considered a wonderful appetizer, and is regularly included for breakfast as a refreshing and energizing start to the day.
Grapefruits are high in fiber and low in calories, and they contain bioflavonoids and other plant chemicals that protect against serious diseases like cancerheart disease, and the formation of tumors. Grapefruits increase the body’s metabolic rate, lower insulin levels and give you a feeling of fullness and normality. It assists the human body in fighting various conditions like fatigue, fevermalariadiabetesconstipation, indigestion, urinary problems, excess acidity and many more.
There are plenty of major health benefits of grapefruits, which are also known to be powerful drug/poison eliminators. It works as a natural antiseptic for external wounds, and it functions as a liver tonic. It contains a high water content, which helps in changing the complexion of the skin and increasing the body’s metabolic rate. The pulp and fiber of grapefruits supply healthy bulk to our food intake, which aids bowel movements and reduces chances of colon cancer. It also helps to quench thirst and thus, reduces the burning sensation that arises during fever. The Asia Pacific Journal of Clinical Nutrition suggests that the intake of grapefruit reduces the risk of developing prostate cancer.

Health Benefits Of Grapefruits

 Appetite Loss: Grapefruit works as an excellent appetite suppressant as compared to many other substances and foods. It is said that smell of the grapefruit reduces the feeling of hunger, which is the reason why people often include grapefruit in their weight loss programs. The high amounts of fiber contained in this fruit can also satisfy hunger and help people avoid the temptation to overeat, since it is a bulky food, and stimulates cholecystokinin to be released, a hormone that regulates digestive juices and acts as a hunger suppressant.
Influenza: Grapefruit is a valuable remedy for influenza, since it helps to minimize acidity in the system. The bitter properties arising from an essence called ‘naringin’ in grapefruits tones up the system and the digestive process. Naringin is also considered a flavonoid, which are powerful antioxidant sources in the human diet. They also have antiviral, antifungal, antibacterial, anti-cancer, and anti-inflammatory qualities, making them one of the most important lines of defense in the immune system, protecting against influenza as well as many other serious conditions.
Malaria: The juice, or the fruit itself, contains valuable and natural ‘quinine’ which is advantageous for the treatment of malaria. Quinine is an alkaloid with a long history of treating malaria, as well as lupusarthritis, and nocturnal leg cramps. It is not an easy component to find in many foods, so grapefruits are a beneficial and rare example. The quinine can be easily extracted from the fruits by boiling a quarter of grapefruit and straining the pulp.
Fever: The pulp or the juice of grapefruit helps patients recover quickly from fevers, and it reduces the burning sensation that occurs when the body reaches a high temperature. It is also known as a way to boost the immune system against colds and other common illnesses. Grapefruit juice, when combined with water, can quench thirst very quickly and can keep you hydrated longer. Most of these benefits come from the high content of vitamin C in grapefruits, which acts as a general immune system defense system and can help the body fight to break fevers.
Fatigue: Grapefruits are also beneficial in the treatment of fatigue, so it can help you to dispel your general tiredness caused from routine or boring work. Drinking equal amounts of grapefruit juice and lemon juice can be a refreshing and delicious way to quickly boost your energy levels. Nootkatone is a very rare and important compound found within grapefruits, and is probably its most valuable component in terms of extracting as an aromatic substance. Nootkatone improves energy metabolism in the body through AMPK activation. This results in higher endurance and energy, increased weight loss, and a reduction in the the chances of developing diabetes.
Indigestion: Grapefruit is useful for solving the problem of indigestion. It is very light as compared to other foods and thus, acts immediately on indigestion by easing the heat and irritation caused in the stomach. It improves the flow of digestive juices, which eases the movement of the bowels and keeps your excretory system regulated. This is due to the presence of fiber and vegetative pulp in grapefruits, that adds bulk to the bowels and regulates your excretory schedule, and grapefruit extract is also often used in modern medicine for these same reasons.
Insomnia: A simple glass of grapefruit juice, if drunk before going to bed, can promote healthy sleep and alleviate the irritating symptoms and repercussions of insomnia. This is due to the presence of tryptophan in grapefruits, the chemical we often associate with becoming sleepy after big meals. The levels of tryptophan in grapefruit juice lets us nod off peacefully to sleep.
Diabetes: Diabetic patients can safely eat grapefruit, because consuming grapefruit can reduce the level of starch in the body. If a patient is diabetic, intake of grapefruit can help them to regulate the flow of sugar in their body, effectively handling the disease. recent studies have shown this beneficial relationship between diabetes and grapefruits to be due to the flavonoid content of grapefruits, along with a number of other healthy benefits from those compounds.
Acidity: Fresh grapefruit juice creates an alkaline reaction after digestion. The citric acid of the fruit is contained in the human body and thus, increases the effect of the alkalinity reaction after digestion. The juice extracted from the grapefruit is beneficial in preventing acid formation and many other diseases that arise due to the presence of excess acidity in the body.
Constipation: A glass full of freshly squeezed grapefruit juice in the morning is a great remedy to control constipation. The juice stimulates the colon and other parts of the body relating to the digestive system. This is due to the stimulating effect of fiber on the secretion and stimulation of gastric juices that ease the constriction of the digestive tract and induce a bowel movement.
Flatulence: 10 to 20 drops of grapefruit juice, taken before all three meals of the day, can work as an appropriate pro-biotic and digestive enzyme, and will relieve excess flatulence and stomach discomfort. Further research needs to be done on the exact mechanism behind this phenomenon, but again, people believe it relates to flavonoid content in citrus fruits like grapefruits.

Urinary Disorders: Grapefruit juice is quite rich in potassium and vitamin C, so it is one of the best treatments for dangerously reduced urination that is often caused by liver, kidney or heart problems. Furthermore, its high potassium content works as a vasodilator, meaning that blood vessels and arteries relax, reducing blood pressure and lessening the risk of heart attacks and strokes. Also, increased levels of potassium have been associated with higher cognitive function because of increased blood and oxygen flow to the brain!
Consumption of Grapefruit is Better than Many Other Medicines
Grapefruits are natural sources of medicine that help the body fight off various diseases. This fruit is readily available in any season. It is completely natural and much better than consuming artificial pharmaceuticals to relieve some of your most basic health conditions. It enables the human body to regulate your cholesterol, which means that it minimizes the risk of various cardiovascular diseases caused by cholesterol issues. The Journal of Agricultural and Food Chemistry shows that consumption of grapefruit can reduce LDL cholesterol (bad cholesterol), as well as hazardous triglycerides.
A Few Words of Warning: Despite all of these health benefits, and the fact that sometimes grapefruits can be superior to other medicines in their efficacy, you must be very careful taking medicine and consuming grapefruit juice at the same time. Certain chemicals in grapefruits, like naringin, and other less common compounds can negatively interact with various drugs and cause damage to your organ systems. Be sure to consult your doctor in terms of drug interactions with grapefruit juice in your diet before beginning any new treatments! You want to improve your health, but sometimes doing it in too many different ways can hurt you!

8 Surprising (And Easy) Memory Boosters

The key to remembering where you put your keys? It could be as easy as these simple tweaks to your daily routine.

PRACTICE GOOD POSTURE

Go thank Mom for nagging you to sit up straight—standing and sitting up straight and tilting your chin up boosts blood and oxygen flow to the brain by up to 40 percent, making it easier to recall memories.

TRY A DIFFERENT TYPE

We’re talking typeface—researchers have found that using an unusual font on study materials can help you remember the content better. Does this mean Comic Sans for your next work presentation? 

WATCH FUNNY CAT VIDEOS

Learning ability, recall, and visual recognition all improved among a group of elderly individuals who watched a funny 30-minute video, one study found. Chalk it up to the stress relief, researcher Gurinder Bains, M.D. says. “With aging, the damaging effects of stress can impair the ability to learn and sustain memory,” he explained. “Humor and the associated mirthful laughter can reduce stress by decreasing stress hormones, including cortisol and catecholamines.”  
  

GO TO HAPPY HOUR

Over 60 years old? Light and moderate alcohol consumption in older adults has been associated with larger volume in the hippocampus and better episodic memory (the ability to recall events).

TAKE REGULAR WALKS

The hippocampus—the brain’s memory center—shrinks as you age, but research has found that older adults who go on walks actually gain volume in the hippocampus.

LIFT WEIGHTS

Prefer to hit the gym? One study had participants lift weights while looking at a series of photos. Two days later, those who strength trained remembered about 60 percent, while those who didn’t remembered 50 percent.

CHEW GUM

It doesn’t get easier than this. Chewing gum has been shown to increase heart rate, blood pressure, and blood flow to the brain, giving you a 15 to 20 minute window of improved memory.

USE PEN AND PAPER

Taking notes in a meeting? Bring a notebook, not a laptop. Writing things down instead of typing them was found to help with active listening and retention.
