| Liquid water found flowing on Mars? Not yet
NEW YORK: Researchers claim to have found no trace of liquid water on Mars, casting doubt on an earlier research which indicated presence of bright spots in some Martian gullies.
"It rules out pure liquid water," according to lead researcher Jon D. Pelletier of the University of Arizona.
Pelletier and his colleagues used topographic data derived from images of Mars from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
The researchers applied the basic physics of how fluid flows under Martian conditions to determine how a flow of pure liquid water would look on the HiRISE images versus how an avalanche of dry granular debris such as sand would look.
"The dry granular case was the winner.
The Savvy Shopper
Plus, it's better than any catwalk in Paris or Milan because it's the clothes real people actually wear. But my version of reality television practically turned to the sci-fi channel's horror night. I actually saw a grown woman swaddled in a full-size fleece blanket. She wasn't the only atrocity. I should have been passing out those funny black bars fashion magazines use when they take a snapshot of a real person on the street that's a dreaded "fashion don't." (One of my fears in life is to open one of those magazines and see the black bar over my eyes. I'm fortunate my life allows these trivial concerns.) I realize comfort is a concern when we're all packed in planes like bargain basement bins. But, really. Must we literally roll out of bed? Here's where this savvy shopper can help. Comfort does not equal giving up style. Let's start with your feet. This spring flats are everywhere. You don't have to smoosh your foot into a pointed toe shoe (though that's what this savvy shopper will be wearing). Ballet flats are big. If you can't imagine hoofing through the airport in those shoes, there are stylish sneakers on the market. Please don't bring your dirty, smelly old basketball shoes. No one wants to watch you take them off when you it's time to go through security. Comfy pants are essential. Pajamas are not pants. Sweatpants don't count. Actual pants. Even a pair of nice jeans get a thumbs up from this frequent flyer. Plan for the changing temperatures. Your plane may actually feel like your destination the sweaty beaches of the Caribbean or the snowy mountains of Colorado. Pair a top with a blazer or jacket for a pulled together look that will help you no matter what the climate. Why does this matter? It's no secret people who look nice and, above all, act nice get better treatment. Maybe that means getting bumped up to first class. Who doesn't want to fly through life with extra leg room? Don't forget to let me know when you see a killer deal pass them along! I'll give them to all my new friends (aka you!) My e-mail is beth.wilkin@wtkr.com.
Dr. Malloy: Neti Pots
One of my patients came in my office with severe nasal congestion and asked if I thought using a neti pot might help. She along with millions of others had learned about it from Dr. Oz on Oprah and was interested. So was I. Here's what I can tell you about neti pots. Neti pots are part of the ancient Indian yoga tradition and now they're going mainstream. The idea is to wash out the nasal secretions and allergens and open up the sinuses. The nasal cavity is the first line of defense against airborne infection and cleansing it may theoretically limit colds and sinus infections as well as relieve dryness. The neti pot is a small pitcher with an opening on top and a spout to place in the nostril. You fill it with warm salt water-1/4 teaspoon of salt to 8 ounces of water.
