Science Current Event-3

Emissions on Diesel engines

          Diesel engines must be treated like gasoline engines, emissions must be met on both. Bio-diesel fuels are getting more popular because it is a renewable substance. These fuels are being tested on buses and trucks with turbo diesel engines to understand the nitric oxide (NO) smoke released from the engine. 

Purpose - stop the gastric release of nitric oxide, give diesel engines emissions

Hypothesis - These tests will work and diesels will be emissions free

Procedure - Use bio-diesel fuels in turbocharged diesel trucks and buses

Results - the bio diesel choked down the (NO) and gained combustion instability

Conclusion - Bio-diesel fuels are the better source for diesel engines

questions

1.) Is the engine healthy after a few months of using bio-diesel fuel?

2.) What is the gastric release now since the bio-diesel is healthier?

3.) Are emissions in general healthy for the motor itself?

SCE-2

New hope for regrowing severed limbs

Despite the human advancements in the world today we cannot grow limbs back such as a lizard can grow its tail back, but, Dr. Mayumi who is a stem cell biologists and dermatologist at NYU's medical center conducted an experiment using mice stem cells, called "Wnts," that have the ability to produce chemicals to regrow bone and flesh. so Via genetic engineering to make the tissue take in the protiens, the team of scientists were able  to regrow bone and flesh!

Purpose -   Regrow limbs for human beings

Hypothesis -  Dr. Mayumi and her group of scientists will be able to regrow limbs

Procedure -  Via genetic engineering, force "Wnts" to produce proteins

Results - "Wnts" was able to produce proteins and grow limbs (bone and tissue)

Conclusion -  This will be a big deal when it comes to amputaions

Questions

1.) Did the team grow the small limbs on mice?

2.) Was this limb making process difficult?

3.) If not difficult, when will this be happening in hospitals?

Science Current event: The Hyperloop

SpaceX/Tesla Motors owner and founder Elon Musk, has just released facts on his "Hyperloop" that can tack passengers and travel from Los angeles to San Francisco California in 30 minutes! The top speed would be near 700 miles per hour. This rail runs on a system called air bearings, different from what bullet trains run on, This system is like an air hockey board, im guessing its going to be a smooth ride.

Science Article Annotation and Summary Practice

Purpose - To extinguish a fire with sounds waves in space
Hypothesis - The sound waves will be able to extinguish the flame in free fall.
Procedure - while inside free-fall, use the sound waves on a candle igniting the the flame.
Results - The sound wave did not put out the flame in free fall but did extinguish it in the lab.
Conclusion - The hypothesis was incorrect.
