This article is about how the University of Michigan invented a tiny generator that makes energy from the vibrations in the air. The vibrations are produced with simple things like traffic, factories, and even people exercising. They were invented by Khalil Najafi and Tzeno Galchev. The good thing about this generators is that they have more abilities than normal devices because they have a better energy source. This genarators use electromagnetic that is coil in a magnetic field and there are three of this generators existed. This generators can produce 500 micro-watts from simple body vibration. This is energy that can be used with a wrist watch and a pace maker. The point of this is to replace batteries specially with in-wireless devices.
Our opinion is that this is a really important invention that can change our life. This is way better than batteries because batteries when all its energies have been used, they take out a poisoning substance that contaminates the world a lot. Also this is a good way of how we can use the bad emissions from factories and traffic. Besides it invites us to do more exercise. It affect us because we are seeing change in our world and some day we will be able to buy this generators and make our lives simpler. We are really happy this event happen and we hope more of this generators are produced as well as more inventions will be created.
The bias are that Khalil Najafi and Tzeno Galchev believed that this is really important and will change the future life. "Mini Generators Make Energy from Random Ambient Vibrations."

This weeks article is about how scientists discover that he banana has the solution to HIV transmission. Bananas contain a part in them called BanLec which is a potent in this fruit. This is really as potent as a two anti-HIV drugs and it is less expensive if it is applied on the vaginal part of the body. Solutions for HIV are really needed so this is a really good solution specially in poor countries where this problem is really affective. What the banana do is to attach to the virus and block its entry to the body. The difficult part is that the chemical needs to be isolated from the banana but it is still possible. Our opinion is that we are happy that this discovery has been found because it will help a lot. We believe as well as other people that using banana is better than using therapies or drugs because they have a longer range of protection and it stops the virus from mutations. Also it is cheaper so it will help poor countries which are the most affected. So now, we will eat more bananas reducing our chance of getting HIV!

This weeks article is about how corral reefs may disappear. Doctor Simon Donner a profesor in the university talked bout how corral reefs become affected by climate change or higher ocean temperature. Corrals get their energy from algae but this algae gets affected when the ocean gets warmer so the corral lacks energy and dies. Based on Dr. Simon that even if we froze emissions today the planet has enough warming to left on it so this is really dangerous for the corrals. A lot of people who live in coast areas get affected because corrals mean a lot to them. The good part is that it seems they won't become completely extinct but they will only live on certain habitats. Our opinion is that this is a really concerning event and it should be stopped. We think that we are ruining our world and we are starting with the corrals reefs. It affects us in the way that it affects peolple that live in the coast areas adn now they won't have enough food or tourism."Will Coral Reefs Disappear?"
