Science is an entity that we created to interpret the behavior of our world. Are we taking on superhuman powers when we attempt to correct our mistakes?In this year of ... More..
Sciences > Geology & Geophysics What will happen when we run out of oil: 1 of 14
Recently, I have followed both the petrochemical and biofuel evolving debate in the Chicago region. As a chemist and concerned citizen I have attended lectures on biofuel by leading researchers and toured petroleum refineries. Many of these events are attended by other scientists in the region. The interest in both petroleum ... More..
Sciences > Sciences (Other) Nanotechnology explained: 2 of 10
Nanotechnology: A Chemist's PerspectiveNano' has been in fashion for a while now. Apple named their iPod Nano for a reason to imply how small it is. But does the general public know what nano' and nanotechnology is? Some of my non-science friends affiliate nanotechnology with computers. Given the 2007 Nobel Prize in Physics f... More..
Sciences > Atmosphere & Weather Removal of excessive carbon from the atmosphere: 2 of 8
How Do We Restore the Balance of CO2?The jury is out on the removal of CO2 from the atmosphere. It has to go. But at the same time we cannot completely get rid of atmospheric carbon dioxide; there has to be a balance. I can think of two main methods to remove it, with biological or chemical means.Biological Remediation of Car... More..
Sciences > Genetics Have breakthroughs in DNA research led to more harm than good?: 8 of 30
Genetic Testing for Behavioral Diseases of the MindGenetic testing can do even more than it already has done by assisting doctors in diagnosing a patient's current medical condition and treatments. Wouldn't it be wonderful to have personalized disease treatment? All this can be done without looking at a person's entire genome... More..
Health & Fitness > Health Care Direct-to-consumer genetic testing: 1 of 3
