Dopamine neurons have a role in movement, new study finds (Nature Neuroscience)

By Catherine Zandonella, Office of the Dean for Research Princeton University researchers have found that dopamine - a brain chemical involved in learning, motivation and many other functions - also has a direct role in representing or encoding movement. The finding could help researchers better understand dopamine's role in movement-related disorders such as Parkinson's disease. … Continue reading Dopamine neurons have a role in movement, new study finds (Nature Neuroscience)

Chemical tracers reveal oxygen-dependent switch in cellular pathway to fat (Nature Chemical Biology)

By Tien Nguyen, Department of Chemistry Using tracer compounds, scientists have been able to track the cellular production of NADPH, a key coenzyme for making fat, through a pathway that has never been measured directly before. By tracking this pathway, known as malic enzyme metabolism, which is one of a few recognized routes to make … Continue reading Chemical tracers reveal oxygen-dependent switch in cellular pathway to fat (Nature Chemical Biology)

Electrons slide through the hourglass on surface of bizarre material (Nature)

By Staff A team of researchers at Princeton University has predicted the existence of a new state of matter in which current flows only through a set of surface channels that resemble an hourglass. These channels are created through the action of a newly theorized particle, dubbed the "hourglass fermion," which arises due to a … Continue reading Electrons slide through the hourglass on surface of bizarre material (Nature)

Same immune-system proteins may first giveth, then taketh away motor control (Brain, Behavior, and Immunity)

By Morgan Kelly, Office of Communications Princeton University researchers have found that a family of proteins with important roles in the immune system may be responsible for fine-tuning a person's motor control as they grow — and for their gradual loss of muscle function as they age. The research potentially reveals a biological cause of … Continue reading Same immune-system proteins may first giveth, then taketh away motor control (Brain, Behavior, and Immunity)

Researchers propose surveillance system for Zika virus and other infectious diseases (The Lancet)

By Catherine Zandonella, Office of the Dean for Research A group of prominent researchers from seven institutions including Princeton University are calling for the establishment of a worldwide program to collect and test blood and other human bodily fluids to aid in the study and prevention of emerging infectious diseases such as the mosquito-borne Zika … Continue reading Researchers propose surveillance system for Zika virus and other infectious diseases (The Lancet)
