In every moment our life style is changing with the help of science. The science has changed our world rapidly. Many discover and invention has made this world like this which is in front of us. We are informing you all about Top 10 Discovers of the Decades. Hope you all are improve your knowledge by these informative article.
Here is the Top 10 Discovers of the Decades. Let’s have a look.
1. Glaciers Melting Fast: When the 21st century began, scientists studying Earth’s climate thought the gigantic ice caps on Greenland and Antarctica would melt slowly around the edges and lag behind the overall global warming of climate. But this past decade, the warmest on record, proved the climate modelers wrong. Glaciers have been melting much faster than ever expected and researchers have been trying to understand why.
2. Human Genome Mapped: Coiled up inside every human cell sit 23 molecules that, if unwound and placed end to end, would stretch about three feet. Those molecules, known as chromosomes, contain all the instructions necessary to build an entire human being. It took more than 10 years and an international collaboration of scientists, but the year 2000 saw a rough draft of the entire human genome, followed by a completed version in 2003.
3. Mars Surface Gives up Signs of Water: In 2008, NASA’s Mars Phoenix lander touched down on the Red Planet to confirm the presence of water and seek out signs of organic compounds. Eight years before, the Mars Global Surveyor spotted what appeared to be gullies carved into the landscape by flowing water. More recently, the Mars Exploration Rovers have uncovered minerals that also indicated the presence of ancient water. But proof of modern-day water was elusive.
4. Stem Cells Found in New Sources: In 2007, scientists from Kyoto University and the University of Wisconsin-Madison, working separately, essentially turned back the clock for adult skin cells, allowing these mature cells, which were preprogrammed to become skin, to act like embryonic stem cells. The adult cells became pluripotent cells, or cells that could end up being virtually any other kind of cell.
5. Humans Meld with Machines: In 2000, researchers at Duke University Medical Center implanted electrodes in monkeys’ brains and then trained them to reach for food using a robotic arm. Such a neurochip could one day restore motor function in paralyzed patients. A team from the MIT Media Lab Europe developed a non-invasive method for picking up brain waves and, in 2004, used those signals for the first time to control the movements of a video game character.
6. Alien Planets Seen Directly: In 2008, astronomers using the Hubble Space Telescope and the infrared Keck and Gemini observatories in Hawaii announced that they had “seen” explants orbiting distant stars. The two observatories had taken images of this alien world. The Keck observation was the infrared detection of three exoplanets orbiting a star called HR8799, 150 light-years from Earth.
7. New Human Ancestors Emerge: In 2002, researchers in northern Chad unearthed the 6- to 7-million-year-old skull of Sahelanthropus tchadensis known as Toumai. Only skull bones have been discovered, so it’s not confirmed whether Toumai walked upright on two feet. But other Toumai remains make a stronger case that it greatly extends the human family timeline.
8. Dark Matter’s Existence Confirmed Directly: n the summer of 2006, astronomers made an announcement that helped humans understand the cosmos a little better: They had direct evidence confirming the existence of dark matter even though they still can’t say what exactly the stuff is. The unprecedented evidence came from the careful weighing of gas and stars flung about in the head-on smash-up between two great clusters of galaxies in the Bullet Cluster.
9. T. rex Tissue Dug from Bone: n 2005, Mary Higby Schweitzer and her colleagues reported in Science the discovery of what appeared to be soft tissues blood vessels, bone matrix and other cells inside the fossilized femur of a small T. rex. Since then, the bones have revealed amino acids that resemble those of modern chickens, firming the link between dinosaurs and birds.
10. Pluto-Sized Eris Rocks Solar System: In January 2005, Mike Brown and his team at Palomar Observatory, Calif. discovered 136199 Eris, a minor body that is 27 percent bigger than Pluto. Eris had trumped Pluto and become the 9th largest body known to orbit the sun. In 2006, the International Astronomical Union (IAU) decided that the likelihood of finding more small rocky bodies in the outer solar system.
These are the main discover in the last decades. This discovers is a legendary step for the future. By reading this article you already have some idea about those discovers.
