Researchers found that R-PIA increased the activity of glutathione, an antioxidant that absorbs free radicals, providing enhanced protection from damage. Animals treated with R-PIA recovered their hearing faster and more completely than those treated with saline, showing less damage to sensory cells.
A Johns Hopkins University professor has built a virtual laboratory to give engineering students hands-on experience with real-world challenges, including oil-drilling simulations and digital logic circuits. The online lab offers a cost-effective alternative to traditional labs, allowing more students to participate and reducing costs.
A UPMC study found that people think more slowly at night due to increased information-processing requirements. After losing a night of sleep, participants showed a slowing in the speed of information processing during the day.
