A solution to injuries from slips and falls may be found underfoot — literally. The footpads of geckos    have hydrophilic (water-loving) mechanisms that allow the little animals  to easily move over moist, slick surfaces. Researchers in ACS Applied Materials & Interfaces report using silicone rubber enhanced with zirconia nanoparticles to create a gecko-inspired slip-resistant polymer . They say the material, which sticks to ice, could be incorporated into shoe soles to reduce injuries in humans. 

It’s peak cold and flu season in the northern hemisphere. These respiratory viruses and other infectious pathogens are spread through close contact and/or touching contaminated surfaces. Many people disinfect their homes to slow viral transmission or take antivirals to improve the recovery process if they get sick. Four papers published in ACS journals provide insights into novel antiviral compounds and methods to inactivate infectious viral particles and bacteria.

Rising carbon dioxide levels affect more than just the climate; they also affect the chemistry of the oceans. When saltwater absorbs carbon dioxide, it becomes acidic, which alters the aquatic animal ecosystem. But how exactly does ocean acidification impact animals whose genetic makeup can shift depending on environmental cues? A study published in ACS’ Environmental Science & Technology addresses this question through the “eyes” of oysters.
