Miniature Needle Delivers Drugs Directly to Brain Cells

March
2018
A needle as thin as a human hair can deliver micro-doses of drugs to millimeter-sized regions deep within the brain.

Earthquakes Linked to Wastewater Injection Depth

March
2018
The relationship between wastewater disposal from oil and gas recovery and earthquakes is becoming clearer. In parts of the U.S. east of the Rocky Mountains, the number of earthquakes has increased dramatically since 2009.

CRISPR-Based Tool Detects Viral DNA

March
2018
A team of scientists led by Jennifer Doudna, a professor of biochemistry and molecular biology at the Univ. of California, Berkeley, has created a new DNA detection system based on CRISPR biology.

Air Pollution from Agriculture Rivals Motor Vehicle Emissions

March
2018
A major source of air pollution may be right underfoot. Agricultural land is responsible for between 20% and 32% of nitrogen oxide (NOx) air pollution in California, according to new research.

For more than 40 years, process intensification (PI) efforts in the U.S. have lagged behind those in other parts of the world. Europe has invested heavily in this research area, and both industry and academia have embraced advances in these technologies — particularly in the chemical and pharmaceutical manufacturing areas, which have seen increases in productivity, energy efficiency, and sustainability. American manufacturing is now awakening from its long slumber and progress is on the horizon.
