Sensor uses DNA to detect presence of lead, a dangerous contaminant

Researchers at the University of Illinois have developed a DNA-based sensor that can detect lead ions in real-time. The sensor uses catalytic DNA with high metal ion selectivity and sensitivity to fluorescence detection, making it an ideal candidate for environmental monitoring and clinical toxicology applications.

Turning salt and water into wine

A new technology called Partial Rootzone Drying (PRD) has emerged as a solution to reduce river water irrigation without exacerbating saline soils. By alternating irrigation patterns, half of the roots can be kept moist while the other half are kept dry, conserving water and maintaining fruit production.

Virginia Tech mathematician named AAAS fellow

Frank S. Quinn, a professor of mathematics at Virginia Tech, has been recognized as an AAAS fellow for his contributions to low-dimensional topology. He is the first person to prove the 4-dimensional annulus conjecture, a theoretical work that aims to understand mathematical structures and potentially connect with high-energy physics.

Plant scientist named AAAS fellow

Kriton Hatzios, a renowned plant scientist at Virginia Tech, has been awarded the prestigious AAAS Fellow Award. He is recognized for his outstanding contributions to understanding the mechanisms of herbicide action and selectivity in crops.

Neuroscience at NIDA: series of satellite symposia will highlight current neuroscience research during annual Society for Neuroscience meeting
