Pay close attention to the rising waxing gibbous moon tonight (Feb. 28), and if you live anywhere in the western hemisphere, you'll be able to watch an excellent demonstration of the movement of the moon in its orbit around the Earth.?

Normally we see the moon rise in the east and then move across the sky, reaching its highest point in the south before descending down toward the western horizon. Of course, this movement is due to the west-to-east rotation of our Earth. But the moon too is also moving in a west-to-east direction in its orbit against the star background, circling Earth at roughly 2,200 miles an hour (3,500 kilometers per hour), the equivalent of its apparent diameter on the sky. Usually though, we're not aware of that movement during the course of a typical night.?

But during an eclipse, when the moon interacts with Earth's shadow, that eastward motion becomes readily apparent. The moon's eastern (left) edge first touches the shadow, and then some minutes later (depending on how deeply the moon plunges into the shadow), it leaves the shadow behind, the last vestige of it disappearing on its western (right) edge.

While it appears that the shadow was creeping over the moon, it was actually the moon moving along in its orbit crossing through the shadow. [Top 10 Cool Moon Facts]

Another way to see the moon's motion through space is to watch when it closely passes a bright star or planet. Such will be the case this evening, when the moon has a close interaction with the bluish first magnitude star, Spica, in the constellation Virgo. Spica is the 16th brightest star in the sky, and soon after the moon comes above the east-southeast horizon at around 9:30 p.m. local time, you'll also see Spica near the moon. What you'll see depends on where you live.

For the eastern United States and Canada, the moon, 87-percent illuminated, will appear above and to the right of Spica as they move up above the horizon. But by 1 a.m. EST (Friday morning, March 1), the gap between them will have narrowed considerably and the moon will now appear just below and to Spica's right; their closest approach to each other.?

If you live in the northeast United States, Spica will appear less than a moon's width from the moon's lower limb. If you live in the southeast United States, they'll appear even closer ? less than half a moon's width from the lower limb.?

You should still be able to see Spica with the naked eye, although the moon will be over 100,000 times brighter; you might want to use binoculars to see it better. The moon will then move slowly away from Spica. By 2:15 a.m. it will appear directly underneath the star as they stand almost due south, and as dawn is breaking at around 5 a.m., you'll see the moon will have shifted noticeably below and to Spica's left.?

From the western United States, Spica and the moon will appear closest together right after they've risen at around 9:30 p.m. PST. Spica will appear very close to the moon's upper left rim, and then the moon will spend the rest of the night gradually moving away to the east. The moon will appear directly below Spica at the stroke of midnight, and at the break of dawn, the moon will have moved directly off to Spica's left.

The most dramatic view will be afforded to those living along the Pacific coast of Mexico and Central America as well as a large swath of South America, where the moon will actually pass directly in front of Spica. We could call this an eclipse of a star, though it's more popularly called an occultation.?

Is reference to the Bible circular in nature? | Compassion in Politics ...

1) In the context of a court room evidence?which is the context of today looking back 2000+ years?the idea of circularity is distinctively different.

2) All worldviews are generally circular unto themselves. Thats the nature of paradigm shifts and ways of viewing the world.

3) The are internal proofs in the Bible.

4) The historical evidence of Jesus is pretty compelling as a source of external justification.

5) Provide additional justifications based on commonly accepted beliefs about how the world works. This is typically what many apolegists tend to do in combination with other methods.

6) Using the methods of logic?cause and effect relationships, metaphors, analogies, and experiential evidence. Arguably these can even help provide some kind of justification for the spiritual and mystical nature of reality?a reality beyond just materialism?that open up the possibility of realms and reality beyond reductionist science

7) Ultimately some issues may need to rely on faith. But all worldviews have some element of faith.

8] Oxford Theoretical physicist Ard Louis has a notion of a tapestry of Truth. The Christian faith is grounded on a tapestry of integrated ideas and proofs.

9) I?m not sure if any of these specifically address this issue, but Resources about Biblical Authority . I might particularly look at the work of NT Wright, as he?s a widely trusted philosopher and theologian.

10) The nature of logical fallacies is heuristic?not eliminative. This is pretty key. Its also the reason why #5 is true.

11) There are multiple authors to the text. This is an integrative proof. For instance, you have a number of apostles and minor prophets, all who write books. They should be treated as independent texts for the purposes of a proof like this one.

MAG completes ?1.5 billion deal to buy Stansted | Buying Business ...

Manchester Airports Group has become the new owner of Stansted after completing its ?1.5 billion purchase of the Essex airport.

MAG, which had its offer for Stansted accepted last month, has bought the airport from Heathrow Airport Holdings, previously known as BAA, which was ordered to sell Stansted by the Competition Commission.

Charlie Cornish, chief executive of MAG, said: ?We?re delighted to have added Stansted to our strong portfolio of UK airports. We aim to help fulfil its potential in the London market and bring more choice to its passengers in the years ahead.

"Today represents the achievement of a major strategic ambition for MAG and we look forward to working alongside staff, partners and stakeholders in ensuring the group?s success.?

MAG already owns Manchester airport as well as East Midlands and Bournemouth which collectively serve more than 23.9 million passengers per year. The company is owned by the 10 borough councils which make up the Greater Manchester area.

Stansted catered for 17.5 million passengers during 2012 although this was down 3.2 per cent on the previous year.

Sir Richard Leese, leader of Manchester City Council, a MAG shareholder, added: "MAG is a key driver of jobs and growth in the north of England and the acquisition of Stansted will help us deliver maximum value for Manchester City Council and the other local authority shareholders.

"A larger, stronger MAG will benefit the whole region and we welcome confirmation that the acquisition has been completed."

'Resistant' Starches Heal the Colon, Prevent Cancer & Diabetes

The Borg had it wrong. Resistance is not futile. In fact, it can stave off colon cancer and ease inflammatory bowel disease and other digestion problems.

The resistance, in this case, comes in the form of so-called resistant starches, certain kinds of carbohydrates that resist digestion in the small intestine and enter into the large intestine, or colon, mostly in the same form they entered your mouth.

These starches ? found in seed hulls, parts of corn and beans, and in room-temperature rice and pasta ? can ferment in the colon to promote the growth of "good" bacteria and have many other beneficial effects.

Researchers at the University of Colorado Denver summarize these benefits in a review paper in the current issue of the journal Current Opinion in Gastroenterology. The review includes the researchers' own findings concerning resistant starch and weight control. [The Scoop on 7 Perfect Survival Foods]

Starch vs. fiber

The word "starch" often is confused with fiber. Both are complex carbohydrates, and both are important for good health. But starch, for the most part, is highly digestible; and fiber is not. Starches are found in root vegetables, tubers, winter squashes, grains and legumes. Your body starts digesting these starches from the moment you start chewing, extracting nutrients and energy.

Fiber is more like the natural packaging for fruits and vegetables, such as the skin or the rigid cellular walls of plants. The human body does not absorb nutrients or energy from them. Soluble fiber dissolves in water, making food more viscous, slowing digestion, and prolonging the feeling of fullness. Insoluble fiber absorbs water and promotes regular and firm bowel movements.

Resistant starch has properties of both soluble and insoluble fiber, said Janine Higgins, lead author on the review paper and associate professor of Pediatrics at the University of Colorado School of Medicine. There are five different forms of resistant starch, she said, and each kind reaches the colon largely unscathed to do its handiwork.

Cures what ails you

Resistant starch might sound like some kind of miracle cure-all, but independent studies have found this substance, more so than ordinary dietary fiber, can help: kill precancerous polyps in the colon; prevent diabetes by improving insulin sensitivity and regulating blood sugar; maintain healthy body weight; reduce inflammation; prevent or treat inflammatory bowel disease; and help promote the growth of beneficial bacteria in the gut.

In 2010, scientists at Virginia Polytechnic and State University reported that resistant starch might also protect against breast cancer.

So, how can a bit of indigestible starch do all this?

"Resistant starch is a very good substrate for fermentation," Higgins told LiveScience. "Instead of being digested by amylases in the upper digestive tract, it passes to the bowel, where it is fermented by bacteria into short chain fatty acids (SCFA). SCFA are acidic, so they lower bowel pH, which facilitates proliferation of good bugs and inhibits growth of pathogenic bacteria. All of this extra fermentation and availability of SCFA provides fuel or energy for the colonocytes [cells lining the colon], which are a barrier against infection."

"Therefore, the lining of the bowel thickens and becomes healthier, and more good bugs colonize and thrive," Higgins added. "In this way, resistant starch acts as a probiotic. Resistant starch also has some of the properties of insoluble fiber, so it increases stool bulk and decreases transit time, both of which are indicators of bowel health."

Also, butyrate, a type of SCFA, seems to be involved in the prevention of bowel cancer, Higgins said.

Most high-fiber, vegetable-based diets will be rich in resistant starches, but some extra care is needed to get them into your diet. For example, pasta and rice have resistant starch, but only at room temperature. So, pasta salad and sushi are better sources of resistant starch. Whole grains, peas, and beans have a form of resistant starch that maintains its structure even when hot, though.

Green banana flour is another source of resistant starch, and it is gluten free.

Christopher Wanjek is the author of a new novel, "Hey, Einstein!", a comical nature-versus-nurture tale about raising clones of Albert Einstein in less-than-ideal settings. His column, Bad Medicine, appears regularly on LiveScience.
