To err is human, to learn, divine

Researchers develop a new model for how the brain processes complex information: by striking a balance between accuracy and simplicity while making mistakes along the way.

This three-square-millimeter filter chip can take the output of low-cost lasers and convert it such that it has the same frequency noise as bigger and significantly more expensive lasers. (Image: Penn Engineering)

State-of-the-art lasers at the micro level

New filter chips created by Penn engineers could enable high-quality lasers at a fraction of their current size and cost.

Ph.D. candidate Tamir Williams will curate an exhibition at Slought titled “A Space to Appear, A Space to Tarry,” which will present works from the photographic series “Black Nightclubs on Chicago’s South Side” (1975-1977) by Penn alumnus Michael Abramson.

The Sachs Program unveils 2020 grants

The Sachs Program for Arts Innovation revealed 34 new art projects from students, faculty, and staff that will receive funding.
‘Nanocardboard’ flyers could serve as Martian atmospheric probes
Graphic rendering of nanocardboard

In this artist’s conception, fleets of flyers could be launched from ground-based rovers and steered with lasers to collect samples. Planets and moons with thin atmospheres and low gravities would enhance these flyers’ ability to levitate by shooting air through their corrugated channels. (Image: Penn Engineering)

‘Nanocardboard’ flyers could serve as Martian atmospheric probes

As NASA plans to launch its next Mars rover, Perseverance, this summer, Penn Engineers are now testing their ‘nanocardboard flyers’ ability to lift payloads.

Lyle Ungar, a professor in the School of Engineering and Applied Science and one of the principal investigators of the World Well-Being Project, which has spent more than half a decade working on ways to grasp the emotional satisfaction and happiness of specific places.

Language in tweets offers insight into community-level well-being

In a Q&A, researcher Lyle Ungar discusses why counties that frequently use words like ‘love’ aren’t necessarily happier, plus how techniques from this work led to a real-time COVID-19 wellness map.

New scavenger technology allows robots to ‘eat’ metal for energy
A robot resembling a toy car attached to a pole turns round and round over a surface covered in hydrogel.

Rather than a battery, the researchers’ metal-air scavenger vehicle gets energy from breaking chemical bonds in the aluminum surface it travels over. The vehicle keeps going until the hydrogel slab it’s dragging dries out or the surface is completely corroded, but a freely moving robot could seek out new sources of water and metal.
