In this article it is basically talking about how the scientists are making new and improved fuel-cells that are stronger than the other ones that we used before the scientists came up with the new fuel-cells. And the new ones are now not only more more stable but stronger to. Now, scientists at the DOE (U.S. Department of Energy) have made something that uses only a single layer of platinum and it makes it more harder to brake it and minimizes the risk of it tearing and wearing off.

Here are some things of the quotes from this article:
"Our studies of the structure and activity of this catalyst -- and comparisons with platinum-carbon catalysts currently in use -- illustrate that the palladium core 'protects' the fine layer of platinum surrounding the particles, enabling it to maintain reactivity for a much longer period of time," explained Brookhaven Lab chemist Radoslav Adzic, who leads the research team.

"This indicates the excellent durability of this electrocatalyst, especially when compared with simpler platinum-carbon catalysts, which lose nearly 70 percent of their reactivity after much shorter cycling times. This level of activity and stability indicates that this is a practical catalyst. It exceeds the goal set by DOE for 2010-2015 and it can be used for automotive applications," Adzic said.

Worm goo conection to corn starch!!!!

In the experiment for the worm goo and the corn starch i saw that the worm goo was instant, and so was the corn starch, but i still think that the worm goo was more instant and faster turning into a solid than the the corn starch did when it turned into that mysterious goo. It took longer for the corn starch to mix with the water because the water was a liquid when it hit the corn starch and the corn starch was still a solid!! So there for the corn starch had to be mixed with our hands or the spoons to make it the actual goo!! So when the liquid (the worm goo) pored into the other liquid it turned into an instant solid!!

Microsensors Offer First Look at Whether Cell Mass Affects Growth Rate

University of Illinois students are using a new kind of microsensors to answer one of the questions in biology.The relationship between cell mass (depending on how much mass your cells have) and growth rate (depending on how fast you are growing). Here is what Bashir, who also directs the Micro and Nanotechnology Engineering Laboratory at Illinois said. "It's merging micro-scale engineering and cell biology," said Bashir, who also directs the Micro and Nanotechnology Engineering Laboratory at Illinois. "We can help advance biology by fabricating new tools that can be used to address important questions in cell biology, cancer research and tissue engineering." He basically said the we can help make biology advanced by making new tools that can be used to address important questions in cell biology, cancer research and tissue engineering. "As you make the structure smaller and smaller, it becomes more sensitive to the mass that's placed on it," Bashir said. He is very right! Just like when today in science class we saw how much water droplets could fit on a penny! The smaller the serfus area(in this case a structure) the it becomes more and more sensitive to the mass that is put on it!

Corn Starch Summarey

What happened when you held it, let it drip, squeezed it, punched it, poked it, scooped it?
When i let it drip it was so liquidey but when I squeezed it or punched it or poked it it emediatley became solid and was very hard.
What happened when there was too much water? When there wasn't enough water?
When there was to much water then it didnt have the rite consistencey, when there wasnt enough water the corn starch was all dryed up and is didnt have any liquid in it and it wasnt acting like normal corn starch!!!!
Did the substance change after time?
Yes it did. When i broght it to my loker i put it in my loker and left it there untill the end of the day. When i looked in my loker at the end of the day i took the korn starch and all of the water had been seperated from the corn starch.
How did your hands react to this mixture?
My hands were very excited even befor we even mixed the corn starch and also will we were doing the corn starch.
What further inquiry (questions or tests) could you do? What tests could you run next time or which ones did you run today that would provide evidence to your conclusion of whether it is solid or liquid material?
I think that me and Ogi could boil the corn starch and saw what hapend. I think that it would just become just corn starch because the water from the corn starch would evaporate from the goo and it would just becom corn starch.
Why is corn starch so special when it is only mixed with water?
It is special because then when it is mixed with water it becomes a liqud, solid. When you poke it or punch it, it becomes a solid but if you leav it in youre hands it will be liqude again.
What are your final thoughts of today's experiment and investigation?

My final thoughts are that it was so awesome!!!!!!!!!!!!!!!!!!!! Me and my partner were so estonished be how the corn starch was driping from our hand and how when we squezed it it became a solid!!!

Clam Cleanup Biologists Clam Up Waterways To Determine Sources Of Pollution

Published: January 1, 2009

Biologists are able to determent what type of toxic stuff is in the water by putting clams in the water so the clams suck up the toxins in the water and then the biologists can see when they detach the bode from the clam its self and then they can test it to see what was in the water. The local high school students had helped the biologists do that.

Some toxins in the water you can see, and some you cant. Like for an Ex, you cant see the chemical toxins that are in the water, but you can see toxins in the water like for an Ex, cups, old tennis shoos, tennis balls, and made even bigger things like bikes, stoves and stuff like that.They can contain very harmful toxins, like they ruin the waterways, what is in the water and it will destroy anything in it.
And here are a few quotes:
"We're using them as pollutant traps," said Harriette Phelps, Ph.D., a biologist at the University of the District of Columbia in Washington, D.C.

"It's been a great experience to actually come and see them and be the ones to pick them up out of the water," student Caitlin Virta said.

"We can trace them back to sources, and then hopefully we can go from there and get rid of the sources," Dr. Phelps said.
