‘Radiolabeling’ lets scientists track the breakdown of drugs (Nature)

By Tien Nguyen, Department of Chemistry A new method for labeling molecules with radioactive elements could let chemists more easily track how drugs under development are metabolized in the body. Chemists consider thousands of compounds in the search for a new drug, and a candidate’s metabolism is a key factor that must be evaluated carefully … Continue reading ‘Radiolabeling’ lets scientists track the breakdown of drugs (Nature)

In rainforests, battle for sunlight shapes forest structure (Science)

New finding helps explain rainforests' influence on global climate By Catherine Zandonella, Office of the Dean for Research Despite their diversity, the structure of most tropical rainforests is highly predictable. Scientists have described the various sizes of the trees by a simple mathematical relationship called a power law. In a new study using data from … Continue reading In rainforests, battle for sunlight shapes forest structure (Science)

PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid (Nuclear Fusion)

By Raphael Rosen, PPPL Office of Communications Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have produced self-consistent computer simulations that capture the evolution of an electric current inside fusion plasma without using a central electromagnet, or solenoid. The computer simulations of the process, known as non-inductive current ramp-up, were performed … Continue reading PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid (Nuclear Fusion)
