for some cops now,math is now used for solving mysteries or finding criminals,a mathematician in maryland invented a method using math to find crooks.most cops believe that if a robber robs again it means his from the area.but the mathematical from maryland thinks that's not accurate.he thinks that the previous crimes may help or the stores that are easier targets.so the mathematician is making a new computer program that will help police find all these informations very quickly using math. census, or survey, information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example that the younger the criminal the closer to home the crime.i agree with mike oleary that math could solve criminal stuff. and it's very important to make programs like this that will help the police to make the world a better place.

My article is about the discovery of Methane in Mars.After five years of researches, scientists have now found and are sure that there is Methane is Mars. In Earth, Methane is used as a byproduct of living bacteria. But the scientists are still not sure of the cause of having Methane. In 2004, the scientists had some thoughts of having Methane, but this year they are sure of finding it. The scientists are still not sure of where does Methane come from, but some guesses think that it might be living off hydrogen produced by rock.

This is important because if the purpose of having Methanr in Mars was the same as in Earth, then life can exist. Methane is used in earth as a byproduct of living Bacteria.So after all of this reaserching the scientists can be sure of having life in Mars of not by finding why is there Methane in Mars. I also agree with this because there is nothing wrong with this discovery that can have any effecs on us or anything. And also I think that its very important and its one of the reasons of finding wheter there is life on Mars or not. A question that still cant be answered.=D

Exoplanet’s Atmospheres had been detected from Earth!
Two independent groups of astronomers have detected the atmospheres of planets around other stars from ground-based telescopes. Previous observations of the atmospheres of extra solar planets had been made almost entirely by space-based instruments, such as the Hubble and Spitzer space telescopes, although another team last year detected the signature of sodium in an exoplanet atmosphere.

This is important because it shows us that astronomers are starting to improve their skills on finding more details about other planets that are way far beyond our universe. If you just imagine how far our planet is from the outer universe, you’re just going to tell to yourself of how we humans are so clever. According to me, this article is one of the best articles I had ever found out, and I will keep encouraging other astronomers or groups to explore more of our surroundings in the universe.

Antractica is warming which is threatening the penguins down there.Sattelites and weather stations stated the antractica is felling the heat and that is hurting the penguins.Scientists studying climate change knew some areas of Antarctica had rising temperatures. But the weather stations inland ,at the South Pole indicated these areas were getting colder. Researchers suspected that the whipping winds and freezing temperatures that grip these interior regions were keeping the rest of the continent cool. To check that out, a group of scientists decided to take a look at the data. The team combined meteorological records from 42 weather stations in Antarctica together with data collected from satellites.The scientists then devised a new estimate of temperature changes in Antarctica.It shows that much of this continent especially the West Antarctic Ice Sheet — had been warming . This region makes up about one-quarter of the continent and has a lower average elevation than does East Antarctica. The analysis showed that,West Antarctica is warming about 0.17 degrees Celsius per decade.Data from penguin rookery in Terre Adélie Antarctica showed that when winter sea ice dropped an average of 11 percent for several years so did the penguins . at that period, the population dropped to half its number. When the sea ice reached high levels, penguin populations remained high. if Antarctic ice sheets continue melting at a high rate, emperor penguins could nearly be wiped out, says Hal Caswell, a mathematical ecologist at the Woods Hole Oceanographic Institution, in Massachusetts.Even if sea-ice melting slow down , the number of penguins continued falling. A study by Caswell and his colleagues studied the current penguin-population changes together with how much sea ice will be available in coming years. These studies showed that the Terre Adélie rookery could host only 400 breeding pairs by the end of this century. Forty years ago, there were 15 times that many.i agree that antractica is warming because of the green house effect and global warming.and i think this is important because penguins are such sweet creatures and we need to have them in this world.

my article is about a car that works on electricity it is called the ultimete aero ev the munufacter is shelby it has 1000 horsepower and it can go from 0 to 60 miles per hour in 2.5 sec its top speed is 208 mph it has a charge that last for 150or 200 mph and it has a charging time of 10 minuts it will be done the first quarter of 2009 its slogon is who says green cnat be mean

i think this is very good because it is better for the infirement and it can be the begining of a new green tecknolygy age it can save our planet earth and it is very pretty and fast
