When fossil fuel CO2 is released to the atmosphere, it essentially accumulates in the relatively rapidly cycling atmosphere / ocean / land biosphere carbon cycle. The atmospheric concentration of CO2 spikes through a time period of CO2 emissions, then is expected to slowly decline over the centuries as CO2 invades the ocean. The “lifetime” of fossil fuel CO2 in the atmosphere is a complicated question because there are multiple processes operating, but in general the CO2 concentration will be higher than natural for hundreds of thousands of years.
Having the knowledge and understanding of scientific concepts and processes necessary to make informed decisions on scientific issues.
Researchers at Princeton University and the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have launched a new center to study the volatile heliosphere — a complex and frequently violent region of space that encompasses the solar system. This region is carved out by the solar wind — charged plasma particles that constantly stream from the sun — and gives rise to space weather that can disrupt cell phone service, damage satellites and knock out power grids.
One of the principal challenges remaining for realizing magnetic fusion energy is to understand and mitigate the chaotic flows of ionized gas, or plasma, that lead to unacceptable energy loss from the hot core of the device. These microscopic, randomly varying, or turbulent, fluctuations of plasma velocity and temperature arise owing to the strong differential in temperature from the hot core (>100,000,000 degrees) to the surrounding wall...
Language-based learning disabilities affect approximately 20% of the population and increase the risk of academic failure. Understanding the role of dynamic auditory processing in the development and disorders of speech, language and reading, coupled with physiological animal research on neuroplasticity, has led to the development of novel neuroplasticity-based cognitive and language training programs disguised as computer games.
Summer is a time that many teenagers prefer to spend relaxing and soaking up the sun at the beach, but 10 high school students at PPPL decided instead to spend their summer soaking up plasma physics knowledge and performing hands-on research.
The high school interns started on July 1, taking a three-day introductory course in plasma physics, offered as part of the program for the first time. Following the course, the students scattered throughout the Laboratory with each assigned a mentor.
