BioEntrepreneurial Idea




Photovoltaic technology is a great idea for a bioentrepreneurial idea because it uses the sun's energy to work some useful items in the house. The sun's energy doesn't affect our enviroment and it helps us save power using oil and gas. Photovoltaics do not pollute the air and it helps the economy. This is very useful to the enviroment and its free. Photovoltaics also do not contribute to greenhouse gases which causes global warming. It's also costs very little money to build photovoltaics, and has no impact on nature.


I think this would be a really good idea for the future because it might stop global warming and it could help save up energy and less pollution in the air. I also find it awesome that you wouldn't need to pay for something like this because all the energy it uses is coming from the sun.

Biological breakthrough


William Roberts and his colleagues made a discovery on rats. They found out that rats are able to track how much time has passed since they last discovered a piece of cheese, but they can't remember where exactly they found that piece of cheese. William Roberts used a experiment to show everyone that rats can remember how much time has passed since they found cheese. He got rats in the 'arms' of the maze at different times of the day. In the maze he placed moderately diserable food pellets and highly diserable cheese. Rats were then being tested on when, how long, or both. This discovery lead researchers to think that episodic-like memory in rats is qualitatively different from human episodic memorys.


I think this is a very interesting discovery because i didn't think rats could actually track how much time has passed since they found cheese. In the future i think rats will be able to remember where they last found the cheese and remember how much time has passed.
