Chinese researchers turn cigarette butts into steel's guardian?

People smoke a lot of cigarettes, which leads to a lot of trash.Tom Novotny has done the math and it has been estimated 5.6 trillion butts each year end up littering the global environment. But a group of Chinese researchers has a solution: recycling. With the data they have collected they found out that cigarette butts makes a great anti-rusting inhibitor for steel.Jun Zhao and Ningsheng Zhang and their colleagues soaked cigarette butts that they found from the trash and along side the roads in distilled water for 24 hours.Then they added some of this cigarette extract to a 10 percent solution of hydrochloric acid, which would ordinarily indent and rust the steel. But the amount of anti-rust dropped by almost 95 percent when another 5 percent of the solution consisted of the butt extract.

Drug Companies Letting You Choose What You Want In Your Drugs?

Drug companies are going to try to sell drugs by letting you decide what you want in it. They are going to try to use netflix's method in order to save a lot more money but they will probably make more money too. With this method people will buy more of that drug to try to save more. For example if you need to take a whole bunch of pill's in this concept you would only have to take one. These companies would save up to $1 billion, if they do this then not only will they get more out of it but hopefully the people get more out of it too. In this case it is a win/win situation.

Earthquake hits Haiti

Haitians took recovery efforts into their own hands Thursday as aid workers trickled into the quake-battered capital. One group of Haitians worked for 24 hours to free a man pinned under a collapsed school. An 11-year-old girl pleaded for water and screamed in pain as a group of Haitians tried to lift a piece of metal off her right leg. They chose to try to free her themselves rather than wait for help from professional rescue workers. Those scenes of Haitians banding together to free their neighbors played out across the capital. Roads leading from the port city's dock into town were crumpled about 5 feet high.

The bug that may have killed a dinosaur

Sue is a famous Tyrannosaurus Rex whose skeleton lives in the Field Museum in Chicago. Small, smooth holes in Sue’s jawbones have been a scientific mystery for years. Scientists may have solved the mystery in Sue’s jaws. A new study suggests that the holes were caused by something much smaller than another dinosaur. Researchers say the holes may have come from infection by a tiny parasite... and that infection may have killed the mighty dinosaur. A parasite is an organism that cannot live on its own. Instead, it feeds and lives on another organism, but this parasite is called Trichomonas. Unlike the dinosaurs, which became extinct about 65 million years ago, different kinds Trichomonas still live on the Earth. A Trichomonas infection can cause tissues to swell and block the throat. It can also cause the jaw to rot and leave holes in the bones.Today, this parasite often infects such birds as pigeons, turkeys and chickens. The scientists caught a break with the skull of an osprey, a fish-eating hawk easily recognized by its dark back and white chest. The osprey had holes in its jaws similar to Sue’s, and the scientists knew that when the bird was alive it was infected with Trichomonas. They started looking at other T. Rex skulls and found nine, including Sue’s, with the telltales holes of a Trichomonas infection.

32 Planets Discovered Outside our Solar System

The European Southern Observatory/Center for Astrophysics announced the existence of the exoplanets, planets outside our solar system. While the use of a high-precision instrument installed at a Chilean telescope it allowed the observatory to detect movements as small as 3.5 km/hr (2.1 mph), a slow walking pace. The tally of new exoplanets found by HARPS is now at 75, out of about 400 known exoplanets. An important find for the study of planet formation was that three exoplanets were around stars that are metal-deficient. Metal-deficient stars are thought to be less favored for planet formation; however, planets the size of several Jupiters were found orbiting such deficient stars.

Tiny T. Rex fossil discovery

A pint-sized version of the Tyrannosaurus Rex, with similarly powerful legs, razor-sharp teeth and tiny arms. The predator, nicknamed Raptorex, lived about 60 million years before the T. Rex and was slightly larger than a man. The fossilized remains were discovered in lake beds in northeastern China. Scientists who have studied the fossilized animal, which was 5 to 6 years old when it died, believe it was an ancestor of the fearsome T. Rex. Based on estimates of other similar-sized theropods, or "beast-footed" dinosaurs, Sereno and his colleagues estimate an adult Raptorex was about 9 feet tall and weighed about 143 pounds. The Tyrannosaurus Rex, which topped the prehistoric food chain until dinosaurs went extinct about 65 million years ago, was believed to weigh at least five tons. Scientists hypothesize that Raptorex ran its prey down, using its enlarged skull, powerful jaws and sharp teeth to dispatch animals much larger than itself. Like the T. Rex, the Raptorex also had tiny forelimbs.
