After closely studying the biomechanics of cats, dogs, and jellyfish, engineers are turning their attention to more bothersome critters: fire ants.
Engineers at the Georgia Institute of Technology examined the notoriously feisty ants more closely and discovered that the hairy surface of their rough skin makes it difficult for water to penetrate, much as duck feathers repel water because of their tiny bumps. Their work could lead to the development of new and better waterproof materials.
Is your lunch fresh enough to eat? Now the plastic wrap can tell you
Consumers often throw away perfectly edible food because they think it has “gone bad.” As a result, the Environmental Protection Agency estimates that food scraps constitute 12 percent of municipal landfills, making food the single largest component of the country’s waste stream.
To help prevent consumers from prematurely throwing away food, researchers are developing a plastic wrap that will change colors when the food is no longer safe to eat.
Qatar, a small Middle Eastern country that has been designated host of the 2022 World Cup, is not known for its mild summers. In fact, temperatures in July regularly average over 115 degrees F (50 degrees C), which presents a serious challenge to the event’s organizers.
But not to fear – engineers from Qatar University’s Department of Mechanical and Industrial Engineering have a clever solution. Over the next ten years they plan to develop an artificial cloud that will hover over the soccer stadium and provide crucial shade to players and audience members.
Scientists may have created an affordable solution for those who live without electricity.
The invention is an artificial leaf, and it is powered by an advanced solar cell that mimics photosynthesis (the process green plants use to convert sunlight and water into energy.)
For the past week, prospective NFL athletes have been competing in the NFL Combine – an exhibition that tests players’ physical and mental abilities. Not only have NFL prospects been working hard to impress coaches with their strength, speed, and intensity, some also have been the first to wear the new biometric Under Armour E39 shirt.
The E39 may look like a typical Under Armour compression shirt, but it is equipped with electronic sensors that monitor heart rate and breathing as well as a triaxial accelerometer to gauge swiftness.
