Summary: The most common contagious human disease is influenza. It usually occurs most during Winter. Vaccines for this disease is very important for elderly old people and also the sick. They have a much higher risk of flu-related health complications than the young. Birds are most likely to blame because that is where the flu orginated. The swine flu started to outbreak during the spring of 2009. it is caused by INfluenza A virus and can affect pigs year round.
Why I chose: It was interesting to read about the orgin of the swine flu and about other types as well. I also chose it because there has been a lot of news on the swine flu

Sun Oddly Quiet -- Hints at Next "Little Ice Age"?
By: Griffin McKinzie
Link: http://news.nationalgeographic.com/news/2009/05/090504-sun-global-cooling.html
Summary: The sun has weirdly been dimmer than before. In the last couple decades this is the only time that it has been this weak. Scientists want to see what’s going to happen next. They want to see if anything out of the ordinary is going to happen. Something out of the ordinary would be if the sun turned off, the sun exploded, the sun lost its juice, or if the sun was blocked off by some space cloud. If any of those things happened it could be hard for the Earth. What do you think? Is the Aztec calendar correct? Will the world end?
Why I Chose this Article?-I chose this article because I was looking for an article and I thought this one would be good. Also other people have been talking about space and I thought I could help out. I think this could be really bad.

"MISSING LINK" PHOTOS: New Fossil Links Humans, Lemurs?
Name: Robby C.
Link to Article: http://news.nationalgeographic.com/news/2009/05/090519-ida-primate-fossil-link.html
Summary: "Ida" was found in Germany. Ida could be the missing link in primate evolution. Ida, which is a fossil known as Darwinius masillae has a lemur like skeleton with opposable thumbs and clawless fingers with nails. Before, scientists were unsure where the primate group that included lemurs split off from the primate group that included humans. Ida could be the missing link between the two. Also, the fact that Ida was found in Germany is interesting to some scientists because it contradicts the fact that most primate evolution came from the African continent. Ida's fossil is so well preserved that scientists are able to pick through bones, fur, and even what she last ate.
I chose this article because I always think its interesting when they discover something new. Also, it was the first article I came across.

Asteroid Attack 3.9 Billion Years Ago May Have Enhanced Early Life On Earth
Author: Will
Link: http://www.sciencedaily.com/releases/2009/05/090520140403.htm
Summary:
A Study done by the University of Colorado at Boulder shows that although there were meteors the size of kansas hitting the Earth, it may have actually helped early life. The results from the study push the initial 3.9 billion years ago date of life on earth all the way back to 4.4 billion years ago. The bombardment of Earth with meteors was said to have lasted anywhere from 20 million years to 200 million years. Researchers concluded that subterranean microbes living at temperatures of 175 to 230 degrees may have flourished during the bombardment period. Planetary scientists also believe that a planet the size of mars glanced off of Earth 4.5 billion years ago. This event would have effectively hit the Earth's reset button.
Why I Chose this Article:
I chose this article because I am really interested in space because it is so vast and large and full of things unknown to humans. I love learning about the events of Earth's early life. I also find this article scary, and that somehow draws me towards it.

Fingerprinting Slow Earthquakes And How They Relate To The Big One
By:

http://www.sciencedaily.com/releases/2009/04/090423142322.htm
Summary:
This article is pretty much what the title says. Carnegie Institution's Department of Terrestrial Magnetism, has found that an unusual layer at the top of a subducting plate coincides with the locations of slow earthquakes and non-volcanic areas. Slow earthquakes take days to release built-up energy instead of just minutes as in regular earthquakes. The scientists have been recording 20 years of seismic data for southern Mexico, where the Cocos plate is slipping beneath the North American plate. Other plants and things on the ground are slipping away in and around other areas as well. Scientists found that slow earthquake areas and the "ultra-slow-velocity" layers cluster together, and that regions of non-volcanic areas are near/next to those clusters. Scientists believe that this all may be subducted oceanic crust at unusually high levels of water saturation. The cause of such "anomalously high pore pressures" is unknown, but a clue might come from the fact that non-volcanic tremors are concentrated in areas with temperatures around 840°F.With all of this pressure and heat, these small earthquakes are just showing signs of possible big earthquakes in the near future. The plants that are slipping away underground also show major movement of tectonic plates.
I chose this article because we are learning about earthquakes and volcanoes. I have also been feeling some earthquakes lately so i thought it was relevant to do some research on them. But for the most part, i just enjoy learning more about earthquakes.

NASA grows algae for biofuel, treats waste
Name : Emily
Link : http://www.msnbc.msn.com/id/30767086/
Summary : Some scientists have discovered algae is good alternative for fossil fuels. They want to grow freshwater algae in nutrient-rich waste water inside plastic membranes. They think that "the natural salinity of the ocean will draw the freshwater out, retaining the plants and nutrients. The membranes prevent saltwater from getting inside and killing the plants, while ocean waves keep the algae mixed and healthy. The process treats the sewage water, which is then released into the ocean." There are some problems with this concept though, like that waste water that had been treated so much would not produce good algae for the whole project. Another problem is that theirs not enough of algae that they've found to replace some oil companies.
Why did you choose this article? I chose this article because I think its very interesting that people are trying so hard to find a replacement for oil usage.

Creatures living on violent undersea volcano give climate change survival clue
By: Mckenna Pearson
Summary:
There is a volcano, underwater, near the island of Guam that erupts so frequently that it has built a new cone 131ft high and 984ft wide in the time span of three years. Bill Chadwick, a volcanologist at Oregon State University said: 'that's as tall as a 12-story building and as wide as a full city block.’ This amazing volcano, named NW Rota-1, has created a habitat in which shrimp, crab, limpets and barnacles, have thrived on. Chadwick said: 'they're specially adapted to their environment and are thriving in harsh chemical conditions that would be toxic to normal marine life.' NW Rota-1 has created a heat source so the animals living on it can thrive and mate at the appropriate times. The animals that have already been living here have adapted to the toxic conditions and can live happily on NW Rota-1. A biologist from the University of Victoria, said that two species of shrimp had revealed intriguing adaptations to volcano living. Her name is Verena Tunnicliffe. Tunnicliffe said 'the 'Loihi' shrimp has adapted to grazing the bacterial filaments with tiny claws like garden shears.’ The second group of shrimp is a new species as well. They are like the first group when they are young, but, when they grow to their adult stage, their front claws grow and, instead of being the prey, they are now the predators. 'The new species attacks the Loihi shrimp and preys on marine life that wanders too close to the volcanic plumes and dies. Tunnicliffe said: 'we saw dying fish, squid, and so on, raining down onto the seamount, where they were jumped on by the volcano shrimp - a lovely adaptation to exploiting the noxious effects of the volcano.'
Why I chose this article:
I chose this article to write my current events journal on because it's interesting and it is also what we're studying, in class, at the moment. I didn't know that volcanoes could erupt under water though. I though that if they did, then the lava would cool so fast that the volcano wouldn't have time to erupt at all. But they can! And I though that was cool. That's why I chose this article form my current event journal.
