Baseball’s ‘magic mud’
 A jar of Lena Blackburne Baseball Rubbing Mud sits on a table beside a muddy, dirty baseball.

Lena Blackburne’s legendary baseball rubbing mud has been a game-day staple for nearly a century, helping Major League pitchers achieve a better grip. Now, researchers at the University of Pennsylvania have scientifically confirmed its friction-enhancing properties, revealing its significance not just in baseball, but also in the broader field of materials science.

New genetic cause of blindness in dogs

In collaboration with a foundation that breeds service dogs for the visually impaired, researchers at the School of Veterinary Medicine at the University of Pennsylvania and the University of Padova in Padova, Italy, have identified a novel variant associated with progressive retinal atrophy in three Labrador retrievers.

New high-definition pictures of the early universe

Research by the Atacama Cosmology Telescope collaboration has led to the clearest and most precise images yet of the universe’s infancy—the cosmic microwave background radiation that was visible only 380,000 years after the Big Bang.

Can surface fractures on Earth, Mars, and Europa predict habitability on other planets?
A view of a planet in the solar system.

(On homepage) A global view of Jupiter’s moon Europa displaying extensive surface fractures—long, curving lines carved into the ice by tidal forces from Jupiter. These cracks hint at dynamic activity beneath Europa’s frozen shell and may provide clues about the moon’s potentially habitable subsurface ocean.

Can surface fractures on Earth, Mars, and Europa predict habitability on other planets?

Geophysicist Douglas Jerolmack has used the mathematical framework developed for understanding fracture patterns on Earth to survey two-dimensional fracture networks across the solar system, which could offer insights into detecting potentially habitable environments on other planets.
