A simple way to boost math progress

Researchers from Penn’s Behavior Change for Good Initiative and their collaborators conducted a megastudy to investigate whether low-cost nudges–informed by behavioral science–could help teachers accelerate student progress in math.

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.

A less clumpy, more complex universe?

Researchers combined cosmological data from two major surveys of the universe’s evolutionary history and found that it may have become “messier and complicated” than expected in recent years.
Fruit fly development offers insights into condensed matter physics

Drosophila melanogaster, the fruit fly, has long been a model species for biologists seeking to understand the molecular mechanisms of animal function and how novelty may arise in organisms. Theoretical physicist Andrea Liu of the School of Arts & Sciences is conducting research on the insect, along with biology and experimental biophysics collaborators at Duke University. Their research has opened the door to an approach that could offer not only a new understanding of how biological function emerges but also suggest a new class of systems in condensed matter physics.

Fruit fly development offers insights into condensed matter physics

Penn Physicist Andrea Liu and collaborators modeled the behavior of tissue during a stage of fly development and found, surprisingly, it doesn’t fluidize as it shrinks but stays solid. Their approach could offer insights physical systems with complex functionality.
