Artificial Retinas Restores Sight
Nelson Hernandez III
Scientists and researchers from the Massachusetts Institute of Technology have recently developed an artificial retina that could restore perfect vision to the blind. They plug it directly into optic nerve and stops progressive diseases witch can eventually lead to blindness unless it is treated immediately. Some drugs are proven to slow the process down, but when the cells are dead, they cannot be replaced. Implants usually cannot restore the sight very well and could only detect a few colors like yellow and grey. With this new artificial retina, sight can be restored to near perfect!

Plastic Bridges Support Tanks
Plastic Bridges Support Tanks
Nelson Hernandez III
The United States Army plans to be putting a new, environmentally friendly technique of bridge building in effect. As appose to standard concrete and wooded bridges traditionally use to make bridges, scientists say that new plastic bridges can be used for military uses. These new bridges are mostly made out of old recycled detergent bottles and car bumpers. The older styles of bridges were expensive and took to long to manufacture. With these new plastic bridges, the military can now make them effectively without spending a ton of money. The bridges are usually used to get across rough terrain and rives that normally couldn’t be crossed. They are made of polyethylene and the plastic from the bottles. The result from mixing these chemicals is a super strong material that can withstand the weight of a seventy-three ton tank! It also requires a lot less regular maintenance which saves the government millions!

Newly developed hydrogel heals broken bones and brain injuries.
Newly developed hydrogel heals broken bones and brain injuries.
Nelson Hernandez III
Scientists and researcher at Celmson University have developed a strange new method of healing bone and brain injuries in the form of a hydrogel. It has been tested on lab rats with serious medical conditions. Around twelve weeks after it was applied, their muscle and sensory functions were practically back to its normal state. Some people suggest that it has the power to replace risky surgeries that people need to keep them alive! I believe that this will soon be a practiced method that all doctors use in the future. Although this still needs to go through a few more clinical trails, it will soon be applied in medical practices.

Watermelon Juice: Renewable Energy Source?
Nelson Hernandez III
Every year, about 20 to 40 percent of all watermelon crops (360,000 tons a year) are wasted and left to rot on the ground. Now scientists and environmentalist have discovered a use for these discarded melons. It is still going threw clinical trails, but scientists say that the wasted fruit can be converted into 9.4 million liters (2.5 million gallons) of pure ethanol fuel every year. Some people suggest that it has the potential to replace corn and sugar cane (what we are using now). However, the melons may not be as efficient in making ethanol as the combination between corn and sugar cane, but they require a lot less water to be added.

Cure for Color Blindness
Cure for Color Blindness
Nelson Hernandez III
US teams of scientist have been doing some research and have been successful in curing an adult monkey of color blindness. Naturally, they can’t sense colors like red and green, but now, this monkey can see them. Besides monkeys, scientists also believe that this technique can be manipulated and used to cure humans as well. It was thought to be impossible to rearrange an adult brain like this, but some theories are being changed. They were able to introduce therapeutic genes into the light sensory cells in the back of the eye. Color blindness is usually caused by disease and certain medicine side effects. The scientists and researchers are going to be setting up clinical trails with humans soon, but they are still testing and researching.

MONKEYS BORN FROM DNA TRANSPLANT!!!
MONKEYS BORN FROM DNA TRANSPLANT!!!
BY: Nelson Hernandez
Scientist and researchers alike have been searching for some time for a way for women to avoid passing on genetic diseases and defects. They have been successful in the birth of four healthy rhesus macaques. Although it is not a very safe technique, experts say that this method is new exiting. This experiment involved the transfer of DNA of two of the monkeys, both of the same species. In the future, scientist plan to use this method to stop diseases by stopping defects in mitochondria. About one person in every four or five thousand has a defect in their mitochondria. However symptoms may be things like muscle weakness, dementia, movement disorders, sight and hearing loss, and heart, muscle and kidney problems. This method still need testing before it is practiced.
