Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

When Olga Troyanskaya's dog Jessy fell ill in early 2006, the vet had painful news.

  - For her senior thesis project, Princeton civil and environmental engineering major Ida Posner is developing a filter that could allow scientists to quickly measure water use by plants like this basil grown in the Princeton EcoHydrology Lab.

  - - Search committee for dean for research established - Princeton Provost Christopher Eisgruber has formed a committee to search for a successor to A.J. Stewart Smith as the University's dean for research.

Princeton University and the Max Planck Society of Germany have joined forces in a scientific collaboration that is designed to accelerate progress in cutting-edge research ranging from harnessing nuclear fusion to understanding solar storms. 

A major effort to study a mysterious substance that could enhance understanding of the cosmos and fusion energy has received a critical boost from the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) .

An emerging class of long-lasting flu vaccines could do more than just save people the trouble of an annual flu shot.

A massive expansion of hydropower planned for the Mekong River Basin in Southeast Asia could have a catastrophic impact on the river's fishery and millions of people who depend on it, according to a new study by researchers including scientists from Princeton University.

  - Molecular biology major Kristan Scott focused his senior thesis on a mutant gene linked not only to colorectal cancer but also to the cancer’s ability to resist chemotherapy.

Differences in factors such as income, education and marital status could contribute overwhelmingly to the gap in life expectancy between blacks and whites in the United States, according to one of the first studies to put a number on how much of the divide can be attributed to disparities in socioeconomic characteristics.

  - Princeton Professor of Chemical and Biological Engineering Bruce Koel is working with scientists at the Princeton Plasma Physics Lab to apply the science of surface chemistry to solving one of the biggest obstacles facing fusion: how to keep the fusion reaction burning for long periods.

  - Edgar Choueiri, a Princeton University professor of mechanical and aerospace engineering, is working to push the boundaries of sound reproduction through his 3-D Audio and Applied Acoustics Lab.

  - Researchers from Princeton University's Department of Civil and Environmental Engineering — from left, Professor Eric Wood, research scholar Justin Sheffield and graduate student Nathaniel Chaney — have created a computer model to track drought in remote or war-torn regions of Africa that are difficult for ground-based observers to reach.
