Students Conceive of Plan to Protect Earth from Space

NASA asked researchers to look into what to do if an asteroid targeted earth. Some enterprising students have decided that gravity is the most efficient (and cheapest) way to deflect big rocks from destroying our small planet. What’s more is that the students have designed their device to perform research on the asteroid as the spacecraft does it thing.

The equipment will collect data on the location and composition of the asteroid and relay it back to Earth. It is considered very unlikely that Apophis will collide with Earth. However, if required, the craft will be sent to it again in 2025 and, using its gravity, will begin to divert the asteroid from its path. Due to the difference in mass between the asteroid and the spacecraft, it will not be able to divert the asteroid with enough force and will need the assistance of the Earth’s mass. Since in 2029, the asteroid is supposed to pass near the Earth, the spacecraft will use the Earth’s mass in order to divert it.

Crystals Absorb CO2 Like a Sponge

This is pretty neat!

The CBC is reporting that a new form of crystal can capture CO2 in a way that seems like magic.

Chemists at the University of California Los Angeles said the crystals — which go by the name zeolitic imidazolate frameworks, or ZIFs — can be tailored to absorb and trap specific molecules.

“The technical challenge of selectively removing carbon dioxide has been overcome,” said UCLA chemistry professor Omar Yaghi in a statement.
The team of scientists created 25 ZIF crystal structures in a laboratory, three of which showed a particular affinity for capturing carbon dioxide. The highly porous crystals also had what the researchers called “extraordinary capacity for storing CO2”: one litre of the crystals could store about 83 litres of CO2.

Feed the Birds to Help them Mate

Birds make nice music, and the birds that there are the more music that is created. To indirectly produce more music one should then feed birds. A recent released study came to the conclusion that feeding birds over the winter helps them procreate.

Those that were given extra food laid eggs earlier and, although the same number of chicks hatched, on average one more successfully fledged per clutch. Although it was well known that feeding birds during winter increases their survival, this is the first time that the benefits to subsequent breeding have been shown.

Leading the research, Gillian Robb, from Queen’s University School of Biological Sciences said “Our study shows that birds that receive extra food over winter lay their eggs earlier and produce more fledglings.”

Dr Stuart Bearhop from the University of Exeter, who supervised the research, said “We show that extra food provided in winter helps the birds that take it, however, we are still unclear whether it has a knock on effect on other species. Nevertheless, I will certainly be continuing to feed the birds in my garden for the rest of the winter.”

Be Lazy When Waiting for the Bus

Waiting for a bus that never seems to come can be one of life’s more aggravating moments. No need to sit around getting all frustrated with underfunded services though. Thanks to the power of mathematics we now know that you should justbe lazy and sit and wait for the bus.

Scott Kominers, a mathematician at Harvard University, and his colleagues derived a formula for the optimal time that you should wait for a tardy bus at each stop en route before giving up and walking on. “Many mathematicians probably ponder this on their way to work, but never get round to working it out,” he says.

The team found that the solution was surprisingly simple. When both options seem reasonably attractive, the formula advises you to choose the “lazy” option: wait at the first stop, no matter how frustrating (www.arxiv.org/abs/0801.0297).

Apple Cider Vinegar Can Solve Nearly Everything

We’ve covered the wonders of vinegar before, and thanks must go out to all the commenters that left their tips on use to vinegar.

Now I’ve found out that apple cider vinegar picks up where regular vinegar drops off. I’ve never heard of this stuff until recently. I wish I could get past the smell so I can enjoy all the health benefits. Here’s a collection of things you can use apple cider vinegar for. Add your wisdom to the comments!

One reader reported that a shot of ACV saved him from going to the emergency room for heart pain. Apple Cider Vinegar also breaks down fat and is widely used to lose weight. It has also been reported that a daily dose of apple cider vinegar in water has high blood pressure under control in two weeks!
