You weight Slightly less ,When the Moon is directly overhead

When the moon is directly overhead, you will weigh slightly less.

Yes, Because your mass is a physical constant - it will not change if gravity changes, it is how much matter you have in you.

Your weight however is the force downward that you experience, it depends on the gravity as well as your mass. For instance, if you were on the moon, which has a gravity around 1/4 of that on earth, you would WEIGH less but your MASS would be the same.

In the situation you described there are two gravities to consider, the pull of the earth down, and the pull of the moon up. Because they are opposite they cancel and your total weight is the difference between these two.

Since the moons pull will be greatest when it is directly above you your weight will be the least at this time. However, because the moon is so far away this gravitational change is very small and so will not be noticible. It would take very sensitive equipment to notice it.

They never Sleep : Ants

Ants are social insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12,500 out of an estimated total of 22,000 species have been classified.

They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies which may occupy large territories and consist of millions of individuals. These larger colonies consist mostly of sterile wingless females forming castes of "workers", "soldiers", or other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens". The colonies are sometimes described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony.

What is Barbie doll's Full name ?

The Barbie doll’s full name is Barbara Millicent Roberts.

Barbie is a fashion doll manufactured by the American toy-company Mattel, Inc. and launched in March 1959. American businesswoman Ruth Handler is credited with the creation of the doll using a German doll called Bild Lilli as her inspiration.
Barbie is the figurehead of a brand of Mattel dolls and accessories, including other family members and collectible dolls. Barbie has been an important part of the toy fashion doll market for over fifty years, and has been the subject of numerous controversies and lawsuits, often involving parody of the doll and her lifestyle.

The Explosive Potential of Methane Frozen Beneath Abraham Lake

LOCATION : Alberta, Canada
While this stunning image of frozen Abraham Lake in Alberta, Canada may look like a perfectly tranquil and picturesque postcard scene, something more menacing – and explosive – lurks beneath the surface. The crisp, bluish-white, cotton wool-like formations are actually frozen bubbles of flammable methane gas trapped in the icy man made lake. As spring sets in and the lake thaws, the bubbles break free and rise to the top. And when the ice cracks, the bubbles escape and vanish into the atmosphere.

The methane in the lake is created when bacteria decomposes organic matter in the water. This organic matter includes plants, leaves, trees and also animals that have died and fallen into the lake. The matter sinks to the bottom, where bacteria begin to break it all down, producing methane in the process.

On top of this, man made lakes and reservoirs are created by flooding dry land – such that the water covers previously existing vegetation and soil and causes them to decompose. Organic matter from natural ecosystems, farms and sewage systems also gets washed into these bodies of water, increasing decomposition rates.

When Abraham Lake is frozen, much older methane from deep beneath the Earth’s crust and ancient oceans remains trapped at the bottom of the lake as a white rock substance known as methane hydrate. As the lake starts to warm up, the methane escapes and comes to the surface. Combined with the methane from decomposition, this creates the amazing-looking frozen columns seen in these photographs. 

This doesn’t just happen in Abraham Lake, either; methane forms in millions of water bodies around the Arctic region as well. Methane is a potent greenhouse gas that has 20 times the effect on climate change than the same amount of carbon dioxide over a 100-year time frame. Unless, that is, it is burned first.

To prove that the odorless and colorless gas released from the frozen lakes is methane, ecologists from the University of Alaska Fairbanks bravely lit some of the volatile emissions on an Alaskan lake – and with some pretty dramatic results. To do this, the researchers poured warm water onto the ice and then used a digging tool to create a hole, before leaning over the hole with a lighter. The results were quite explosive – like a fire breather performing from beneath the ice.  

Emissions of methane are on the increase. Ecologist Katey Walter Anthony of the University of Alaska Fairbanks warns, “When we look at how much carbon is in permafrost still frozen and the potential for that permafrost to thaw in the future, we estimate that more than 10 times the amount of methane that’s right now in the atmosphere will come out of these lakes.”

          Although methane seeping from lakes is one thing, it was once thought that permafrost in cold seas was keeping a lot of the gas trapped – yet it appears that this is no longer the case. In a 2010 National Geographic article, University of Alaska Fairbanks biogeochemist Natalia Shakhova explained that, in recent years, “The permafrost is actually failing in its ability to preserve this leakage.” According to Shakhova and her colleagues, around eight million tons of methane a year is emitted into the air from the Arctic Ocean’s East Siberia Sea alone, which brings with it the threat of increased global warming.

 When you think about how potent and volatile methane is as a gas, and you consider the fact that massive half-mile-wide bubbles were found in the Arctic Ocean a few years ago, you realize just how serious and potentially dangerous a situation this could be. Still, it’s not all bad. 

In early 2013, Japan became the first country to successfully extract natural frozen gas from deposits of icy methane hydrate buried in the ocean floor. According to experts, the amount of carbon stored in these types of gas deposits across the globe is staggering, and the idea of tapping into this newfound energy reserve could mean big things for countries with scant energy resources.
