There would be no oil shortage if we could use our coal, since we have LOTS of it. But burning it releases greenhouse gases, and what we need most is a clean way to power cars.

Researchers Burt Davis and Rodney Andrews are exploring ways to increase the efficiency of converting coal to liquid fuel. Davis says, "North America is one of the world’s largest coal-reserve regions. Its petroleum is declining, but coal is still the largest resource. If the United States is to become independent from foreign sources of petroleum, it has to make it from oil shale, coal or both. We have about equal amounts of reserves of oil shale and coal, at the current rate of usage, to be able to generate petroleum substitutes for the United States for the next 200 years."

Not everyone thinks we should be investing so much time and money in the ISS, but there’s more than one reason to return to the moon: while it’s a source of a potentially perfect fuel to some nations, to climate change researchers, it represents the ideal place from which to study climate change on Earth.

Researcher Shaopeng Huang has found that surface temperatures on the near side of the moon accurately record important information about Earth’s climate system. Based on his analysis, he is calling for an international effort to develop and deploy monitoring stations on the moon for the study of global warming here on earth.

Almost all of us have lost friends and parents to cancer. Surgery, radiation and chemotherapy can prolong a patient’s life, but now there’s hope for a real CURE to this dreaded disease.

Scientists have learned how to create stem cells from human fat and turn them into “suicide genes” that seek out and destroy tumors like tiny homing missiles. Researcher Cestmir Altaner says, “Nearly everyone has some fat tissue they can spare, and this tissue could be a source of cells for cancer treatment that can be adapted into specific vehicles for drug transport.”
