A new research and training facility at Imperial that will construct DNA at industrial levels has been announced today by the Universities Minister. Designing‚ constructing and testing DNA is a crucial element of synthetic biology‚ an area of science which combines biology and engineering to create new biologically based devices that will help solve a range of different global challenges. These devices are made from harmless cells‚ such as yeast cells. Manmade yeast genes could then be used to

SAT testing is not an appropriate method of measuring a student’s overall intelligence. This popular standardized test is offered in over 176 countries‚ including the United States. The SATs can be the deciding factor of college acceptance‚ making the exam itself too influential on a student’s future. Additionally‚ the test has been taken advantage of numerous times for higher scores. The legitimacy of the SATs is also questioned with the issue of income inequality. Most students in the 21st century
