Deep down you know you a little feelings for the little flipping mammal. It all relates back to when you are young at the local Dolphin show. Dolphins are one of the smartest animals. In Austria there has been a discovery in Dolphin feeding. They feed on fast small fish. Dolphins have been having trouble catching their peer. There is a small group of dolphins that have find a way to bet the survival of the fittest. The head dolphin runs in a tight circle pushing its tail down hard on the sand causing a thick dark cloud. The small fish response by going crazy. The Dolphins just wait and their food is literally handed to them. Scientist were amazed by the creativity this mammals have shown. If its from the local Dolphin show too Austria where they are finding new discoveries every day on survival.
Skin cancer is caused by the uncontrollable growth of abnormal skin cells. It is usually detected from an irregular looking mole on your skin. If left untreated, it can develop into a serious fatal illness spreading quickly from the skin into tissues and organs. It is very dangerous. The main cause of skin cancer is the UV rays from the sun. Not all cases of skin cancer are from the sun. In some cases it is inherited through your genes, and unfortunately, there is nothing that can be done.
Many of us enjoy soaking up the son and getting tan, I admit it myself. If people come to the beach on holidays they sit at the beach for most of the day and frazzle their skin.
When you are running around outside for many hours playing your sport in Florida, you don’t realise the effect the sun is having on your skin. That is why you need to wear sunscreen and a hat!
Monday, November 16, Linda Mayberry (Social Studies department) and I drove over to Kennedy Space Center for the launching of the space shuttle Atlantis. The entire Visitor’s Center was open, so we explored the exhibits and looked for a good place where Linda could watch the launch. I had received a special invitation, so I would be going to a different location to view the launch. I had no idea how good that location would be.
I boarded a bus and found myself at the viewing site for family members and friends of the shuttle astronauts. This is the closest location from which spectators can view a launch, 4 miles. People there were talking about their friends / roommates / flight buddies who were going on the mission, and I could feel the excitement and anticipation as the countdown wore on. Every time an announcement said that another system checked out the crowd would break out in applause.
Finally the countdown got close to zero. At T minus 3 minutes NASA played the National Anthem. Just before the launch I photographed a Bald Eagle flying by. The crowd counted down the final ten seconds with the announcer. When the first plumes came from the launch pad a cheer went up. Then the shuttle rose on a pillar of fire, cleared the tower, and the crowd roared.
As the shuttle neared the clouds, the sound from the launch finally reached us. While it was not as loud as I expected, I could feel the concussions from the roar and crackle of the engines. The shuttle continued to climb, and we watched it until the solid rocket boosters separated. Then we made our way back to the buses and returned to the visitor’s center.
It was cool to overhear people talking. Many were moved to tears knowing that their best friends or family were fulfilling lifelong dreams of traveling into space. I realized as I listened that I was a spectator; these people were participants. Even though I found the launch exhilarating, the launch meant more to them than I will ever understand.
STS-129 was my first attended shuttle launch. Everything worked perfectly, and there were no delays or postponements. I was a recipient of a marvelous opportunity, and I experienced something I will never forget. — Eric Van Zytveld
Every November, Earth gets a glance of meteor light in the night sky. This year is not different. While Asia will be getting the most mesmerizing meteor show this year, we will also be getting a natural entertainment. The Leonid meteor shower is coming this morning, at 3:30 am and the shower will run from then until about 5:30 am. There should be 20 to 30 meteors per hour in America and as many as 200 to 300 per hour over in Asia. With the weather like tonight’s, nothing will stop us from seeing the Leonid meteor shower. So please, spread the news and set your alarms to 3:30 am! I don’t know if you have heard this before but wishing upon a meteor is very effective! Having a wish come true is definitely worth waking up for! Even if you do not believe in these “girly” beliefs, you should still not miss the chance because as damaged and polluted as the earth is now (this is just my opinion), it would not be surprising that we will never get to see this again. Besides, it could be a romantic night with your other half and maybe you can even repair a broken relationship or even better, mend a shattered heart.
Enjoy the show and don’t forget to make a wish!
Astronomers from the European Southern Observatory (ESO) have discovered 32 new planets orbiting various stars in the galaxy. The discovery was made at the La Silla observatory in Chile thanks to the High Accuracy Radial Planet Searcher or Harps. The Harps spectrograph is connected in turn to a 3.6 meter telescope and has considerably contributed to the 400 exoplanets, or planets that exist outside of our solar system, that have thus far been found. Because the planets aren’t visible even through the most powerful telescopes, they had to be found by analyzing the wobble that their stars underwent as each body pulled on the other. Although none of the planets seemed inhabitable or particularly unusual, the importance of these discoveries relates to the masses of some of these bodies. While a good number of high mass planets made up of toxic gasses were found, it was the lower mass planets that were exciting. Massive gas planets were thought to make up the vast majority of exoplanets, severely reducing the probability that life could exist elsewhere in our galaxy, but, according to the ESO, as many as 40% of stars in our universe could be orbited by a planet of similar mass to Earth.
While NASA’s LCROSS success crash landing onto the moon was spectacular, now that the probes and sensors have all been deployed, the real science can begin. The surprises came right from the landing as excessive levels of sodium have been detected, and while it was known that some percentage of the lunar surface was made up of the highly active metal, the concentration is much greater than expected. LCROSS identifies elements and compounds using its many spectrometers. Spectrometers compare which frequencies of light pass through certain substances with known elemental frequencies. These devices are highly accurate, and it is hoped that they will be able to detect water if any is present. The probe, however, has even more up its sleeve. Microwave ovens work by exciting water molecules by emitting electromagnetic waves at the frequency at which water resonates. LCROSS is also armed with a microwave emitter, and it was hoped that energizing molecules of water would make them easier to detect. Unfortunately, no water has been found thus far on the moon, but the abundance of hydrogen found on other moon missions keeps hopes high.
Abortion is the termination of a pregnancy by the expulsion from the uterus of an embryo, resulting in or caused by its death.
Abortion has a long story and has been induced by various methods. The herbal abortifacients, the use of sharpened tools, physical trauma and medications to induce abortion. The legality, prevalence, and cultural views on abortion vary substantially around the world. In many parts of the world there is prominent and divisive public controversy over the ethical and legal issues of abortion. Abortion and abortion-related issues feature prominently in the national politics in many nations often involving the opposing pro-life. Incidence of abortion has declined worldwide, as access to family planning education and contraceptive services has increased. Abortion incidence in the United States declined about a 8% from 1996 to 2003.
The types of abortion are medical and surgical abortion. The medical abortions is only used in the first trimester of pregnancy. The medical abortion is the 10% used in the United States and Europe. Surgical abortion it is used in the first 12 weeks, suction-aspiration or vacuum abortion is the most common method.Manual Vacuum Aspiration (MVA) by suction using a manual syringe, while electric Vacuum Aspiration (EVA) abortion uses an electric pump.
