Simple and inexpensive, an artificial nose senses smell by seeing colors

Researchers have developed an artificial nose that senses smell by visualizing color changes in metalloporphyrin dyes, offering improved sensitivity and humidity resistance compared to human noses. The technology has various applications in industries such as food and beverage, perfume, customs checkpoints, and chemical workplaces.

Vaccine put into tomatoes shows promise fighting virus in lab tests

Researchers at the University of Illinois have developed a vaccine approach to fight the respiratory syncytial virus (RSV) by infusing it into genetically modified cherry tomatoes. The study found that mice fed with these vaccine-containing tomatoes showed increased antibody production, providing protection against the virus.

Heat capacity of glassy substance holds key to its transition kinetics

University of Illinois researchers have developed a theory that explains how glassy materials behave and predict the speed of molecular motion changes with temperature. The theory, based on thermodynamic measurements of heat capacity, provides a universal form for expressing glass transition phenomena.
