What do glass, dirty ice, and riverbeds have in common? All are disordered solids, meaning they have malleable internal structures that can rearrange themselves over time.

Since 1955, the Alfred P. Sloan Foundation has granted yearly fellowships to early-career scientists and scholars whose achievements and potential identify them as the next generation of scientific leaders.

Electric cars may be the future of driving, but first, the vehicles need to spark excitement among the general public. That’s why Penn students have been working hard for the past two years to build one of the world’s first electric racecars.

Coding may be a way of life for top collegiate hackers, but even the best of the best are pushed to their limits during PennApps, the nation’s premier student-run hackathon.

Mutualism—an ecological interaction between different organisms that benefits both—takes many variations in nature.

Contaminated wastewater produced during hydraulic fracturing, or fracking, is a major environmental concern associated with natural gas extraction. Fracking involves pumping large amounts of water into underground rocks to release the natural gas stored within. When this water returns to the surface, it brings with it contaminants, including oils, salts, and heavy metals.

While gender gaps are narrowing in most science, technology, engineering, and math fields, the share of women studying computer science has declined from a peak of roughly 35 percent in the mid-1980s to less than 20 percent today.

Each semester, top collegiate hackers from around the world convene in Penn’s Engineering quad for a weekend of nonstop coding. PennApps, the nation’s largest and most prestigious student-run hackathon, marked its 10th edition on Sept. 12-14, with more than 1,200 student hackers.

Last fall, the Penn Center for Innovation (PCI) launched the AppItUP Challenge, a contest that collected mobile app ideas from across the University and helped bring the best ones to life. The 2013 challenge yielded 185 ideas from 11 of Penn’s 12 schools.
