Artic Melt Season Getting Longer

http://http://www.phschool.com/science/planetdiary/archive10/atmo1031510.html

With all the news going around about global warming,it comes to no surprise that the melt season in the artic is growing longer.Every year,a few of the sea ice melts in the summer and refreezes in the winter. Now a new NASA study shows the melt season is starting earlier and lasting longer.Usually the melt season starts the day in spring when ice stops frezing and melting is continous. The season ends when when the ice begins to freeze again.Furthemore,data shows the melt season increased,on average,more than six days per decade.These changes are most dramatic along ice pack edges at the lower latitudes.There, the melt season is as much as 40 days longer per decade. The changes in the melt season are accelerating because melting itself leads to more melting.Likewise, dark ocean water absorbs more solor energy than mirror-like ice.Therefore, an earlier melt season allows ocean water to soak up heat for a longer time,the extra heat delays refreezing,Moreover, I think that this article gives a sense of realizm as to what is happing to the ice in the much colder regions,yet cant this not be part of how the earth works?Greenhouse gases effect this rapid change, but can't the earth make its own defence mecanisim in order to protects itself?.Animals change the way they live to go along with the changes in their enviroment.Even though earth is not alive is has been changing for many milleniues.

Surprising Sea Slug Is Half plant,Half animal

A green sea slug appears to be part animal,part animal.It is the first critter discovered to produce the plant pigment chlorophyll.These slugs seem to have stolen the genes that enable their skills from algae they have eaten .With the combiened genes,the sulgs can carry photosynthesis(process plants use to convert sunlight into enery).A biologist Sidney Pierce of the University of South Florida has been studing these unique creatures for 20 years and presented his finding to the Society and Comparative Biology in Seattle,but Science News reported this finding first. Offically called Elysua chlroratica these sneaky unique creatures live in salt marshes in New England and Canada.Also the slugs steal tiny cell parts called chloroplasts which they use to conduct photosynthesis.Therefore,reserchers use radioactive tracers to be sure that the slugs are actually producing the chlorophyll themselves as to stealing the pigment from algae.The slugs incorporate the genetic matirials so well they pass it to further generations.The baby slugs have the ability to produce their own chlorophyll,but they cant carry out photosynthesis until they have eaten enough algae to steal the necessary chloroplats.Moreover,this connects directly to science because this is an example of evolotion the slugs pass on important survival skills in the genes of their further generations.In my opinion this is an intresting find because plants and slugs are two different spicies and now they are one.http://www.livescience.com/animals/green-slug-animals-100112.html

Interviwing an Oceanographer

I interviewed "Lena Delta" an oceanographer.On my "T.V Channel" C.E.C (College Education Channel).On her boat we talked about her job.

Burning Suger

This week in class we did a lab on burning suger.We placed a test tube containing two suger cubes in the flame.In this lab we learned what occures when suger is burned. Soon the buttom of the test tube began to burn so did the suger its self and smoke was coming out from the top of the test tube.After the burnt suger cooled,we observed it.The new substance was a brown-black color.The hardness was somewhat dense and solid and the texture was rough,hard and smooth.In the end my group learned that the suger was not still present because when suger is burnt it turnes into ash and the water in the suger dissolves.In my opinion I think this lab was fun and it help me better understand pysical and chimical changes.

Nearly 3 Dozen Planets Found

Ever wondered if there are more planest oustide of this solor system.? Well Astronomers announced the discovery of 32 extrasolor planets.Some are five times the mass of Earth and the others are five times heftier than the biggest planet in our solor system Jupiter.Therefore,in class we are studing density which has to do with mass.These new planests were found with the HARPS(High Accuacy Velocity Planet Searcher) spectrograph on the European Southern Observatory's.The HARPS program survayed about 2,000 stars for five years.The particular aim is for looking at solar-type stars for low-mass planets .In my opinion I think this is a great find.These new findings can help us find planets exactly like our own so one day we can explore it and live on it.

Man-sized Dinosaur was a tiny T.Rec

We always thought that the T-rex was the one and only of its kind but,a new find has changed that theroy. A miniture tyrannosauras;It may have been tiny but it had the same fierce features of its bigger cousin.Moreover,the newly discovered dinosaur is not a T-rex but, a turanosaurid.It lived tens of millions of years earlier than its mighty cousin.Weighing in at a measley 150 pounds with a body length of just 9 feet(2.7cm).This new find remians unearthed in the northeast of China .Likewise,cientistist found that the Tyranosaurid(Raptorex)had tiny forelimbs,long legs for quick runnig,powerful jaw muscles,an oversized head,and an enlarged olfactory bulbs that suggestes that this predetor had an expert sense of smell."Many of these traits have never been found in anything but the big brutes"said Paul Sereno of the University of Chicago.All in All i think that this dicovery is intresting but, what if this is a baby dinosuar?.
