Genes for age-related cognitive decline found in adult worm neurons (Nature)

By Staff Researchers from Princeton University have identified genes important for age-related cognitive declines in memory in adult worm neurons, which had not been studied previously. The research, published in the journal Nature, could eventually point the way toward therapies to extend life and enhance health in aging human populations. "The newly discovered genes regulate … Continue reading Genes for age-related cognitive decline found in adult worm neurons (Nature)

Using powerful computers, physicists uncover mechanism that stabilizes plasma (Physical Review Letters)

By Raphael Rosen, Princeton Plasma Physics Laboratory Communications A team of physicists led by Stephen Jardin of the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has discovered a mechanism that prevents the electrical current flowing through fusion plasma from repeatedly peaking and crashing. This behavior is known as a "sawtooth cycle" and can … Continue reading Using powerful computers, physicists uncover mechanism that stabilizes plasma (Physical Review Letters)

Warm nights could flood the atmosphere with carbon under climate change (PNAS)

By Morgan Kelly, Office of Communications The warming effects of climate change usually conjure up ideas of parched and barren landscapes broiling under a blazing sun, its heat amplified by greenhouse gases. But a study led by Princeton University researchers suggests that hotter nights may actually wield much greater influence over the planet's atmosphere as … Continue reading Warm nights could flood the atmosphere with carbon under climate change (PNAS)

PPPL physicists propose new plasma-based method to treat radioactive waste (Journal of Hazardous Materials)

By Raphael Rosen, Princeton Plasma Physics Laboratory Communications Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are proposing a new way to process nuclear waste that uses a plasma-based centrifuge. Known as plasma mass filtering, the new mass separation techniques would supplement chemical techniques. It is hoped that this combined … Continue reading PPPL physicists propose new plasma-based method to treat radioactive waste (Journal of Hazardous Materials)

Dolphin-disease outbreak shows how to account for the unknown when tracking epidemics (Journal of the Royal Society Interface)

By Morgan Kelly, Office of Communications Stopping the outbreak of a disease hinges on a wealth of data such as what makes a suitable host and how a pathogen spreads. But gathering these data can be difficult for diseases in remote areas of the world, or for epidemics involving wild animals. A new study led … Continue reading Dolphin-disease outbreak shows how to account for the unknown when tracking epidemics (Journal of the Royal Society Interface)

Identifying new sources of turbulence in spherical tokamaks (Physics of Plasmas)

By John Greenwald, Princeton Plasma Physics Laboratory Communications For fusion reactions to take place efficiently, the atomic nuclei that fuse together in plasma must be kept sufficiently hot. But turbulence in the plasma that flows in facilities called tokamaks can cause heat to leak from the core of the plasma to its outer edge, causing … Continue reading Identifying new sources of turbulence in spherical tokamaks (Physics of Plasmas)
