- Sensory response to environmental stimuli modulated by form of vitamin B3 in worms
- 12 October 2016 — Experiments show that too much of a form of vitamin B3 -- nicotinamide -- that is produced naturally inside of cells can lead to cell death in certain sensory cells and cause behavioral changes in the worm, Caenorhabditis elegans. The research, by a team of Penn State scientists, shows that excess nicotinamide causes overactivity of the TRPV ion channel that is involved in sensory perception by controlling the movement of certain charged particles in and out of cells. The work also provides clues to the mechanism causing the cells to die, and links these cellular processes to behavior. A paper describing the research is published in the October 12, 2016 edition of the journal Nature Communications.
- New, carbon-nanotube tool for ultra-sensitive virus detection and identification
- 07 October 2016 — A new tool that uses a forest-like array of vertically-aligned carbon nanotubes that can be finely tuned to selectively trap viruses by their size can increase the detection threshold for viruses and speed the process of identifying newly-emerging viruses. The research, by an interdisciplinary team of scientists at Penn State, is published in the October 7, 2016 edition of the journal Science Advances.
- Using satellite images to better target vaccination
- 07 October 2016 — A team of researchers led by Penn State scientists have combined satellite imagery, vaccination records, and measles case reports to illustrate how using predictable population fluctuations can help to improve vaccination coverage -- a vital factor in combatting infectious disease outbreaks. The research is published in the October 5, 2016 edition of the journal Scientific Reports.
