The Physics of Sliding on Ice

Share This Post

Want to know what makes an ice skating rink slippery? Researchers have developed a mathematical foundation explaining the science behind the slickness of ice. They measured the forces from objects used to push against the ice at different temperatures, pressures, and speeds to come up with molecular-level explanations. According to their results, the slickness is a result of a phase transition (when a material changes from one state to another). The liquid that forms on the surface carries similar properties to those found in both frozen ice and liquid water. Read full article here

The First Solar-Powered Car Comes at a Hot Price

The Lightyear O is a revolutionary electric car powered by the sun. Developed by a Dutch startup, the four-door sedan has over 50 square feet of solar panels on its roof and hood, generating up to 43 miles of energy a day. With production now underway in Finland, the car does come with a hefty price tag at $262,000, but the company hopes to introduce a more affordable version, the Lightyear 2, by 2025.

Magneto Protein Could Help Magnets Control Brain Circuitry

This groundbreaking research by scientists at the University of Virginia has demonstrated a novel way to control the nervous systems of zebrafish and mice using magnets. This method, called magnetogenetics, involves inserting genetic constructs into neurons to make them sensitive to magnetic fields, providing a more precise and non-invasive way to control and manipulate neural circuits than traditional methods. This could one day revolutionize the treatment of brain disorders in humans. Read full article here
