The art of talking about science
Paul Offit of Penn Medicine and CHOP offers five tips for better communicating tough scientific topics to the public—and standing up for science in the process.
A physical model for forming patterns in pollen
Physicists have developed a model that describes how patterns form on pollen spores, the first physically rigorous framework that details the thermodynamic processes that lead to complex biological architectures.
The dynamics of light-harvesting chemistry
A new paper provides insights into the chemistry that underlies human-made, light-driven catalytic systems and paves the way to better understand how light-induced reactions can be controlled more effectively.
How one gene in a tiny fish may alter an aquatic ecosystem
Linking genomics to evolution to ecology, the work takes an unusual approach to reveal broad implications of how species adapt to their local environment.
Supreme Court decision a boon for truck drivers and, potentially, the gig economy
Three Penn experts discuss the ruling, which gives transportation workers the ability to sue their employers in class-action lawsuits, sidestepping forced arbitration.
Infection-resistant catheter plan wins Y-Prize
The team of four undergraduates propose reinventing the catheter to prevent urinary tract infections at the source, using a wrinkle printing technology developed at Penn.
‘Metallic wood’ has the strength of titanium and the density of water
In a study published in Nature Scientific Reports, researchers at the School of Engineering and Applied Science, the University of Illinois at Urbana–Champaign, and the University of Cambridge have built a sheet of nickel with nanoscale pores that make it as strong as titanium, but four to five times lighter.
The physics of multitasking
Penn physicists characterize the limits of multitasking in biological networks, paving the way for future applications in fields from biology to medicine.
Designing with resilience to prepare for a changing world
Urban designers joined with architects, engineers, city planners, sociologists, and other experts to share strategies for adapting to rising sea levels, fiercer storms, and sinking shorelines, coinciding with the launch of the Certificate in Urban Resilience at the School of Design.
Engineers 3D print smart objects with ‘embodied logic’
Researchers at the School of Engineering and Applied Science have taken inspiration from the sorts of systems embodied in Venus fly traps, utilizing stimuli-responsive materials and geometric principles to design structures that have “embodied logic.”

A new insulation material is practically weightless yet still durable
The School of Engineering and Applied Science’s Deep Jariwala commented on a new, nearly weightless insulation material made of porous aerogel capable of withstanding temperature shifts of over 1,000 degrees Celsius. “It’s notoriously hard to make materials that are not just lightweight but can also be heavily heat resistant.”

Have you heard the buzz? Honeybees can count
Elizabeth Brannon and postdoc Rosa Rugani of the School of Arts and Sciences discussed new research about honeybees’ ability to add and subtract numbers. Brannon said bees use ratios, rather than exact digits, to understand quantities. “When animals are comparing two numerical values, they’re much better if they differ by a large ratio than if they differ by a very small ratio,” she said.

People don’t trust blockchain systems—Is regulation a way to help?
The Wharton School’s Kevin Werbach wrote about blockchain and the contradiction between its “allegedly trust-less technology and its trust-needing users.”

The false trade-offs of personal data protection
The Annenberg School for Communication’s Joseph Turow was cited for his research, which found that most Americans don’t believe trading data for discounts is “a square deal.”

Blue pigment in 1,000-year-old teeth links women to the production of medieval manuscripts
The Libraries’ Nicholas Herman offered commentary on a study that used bio-archaeology to identify ultramarine in the dental tartar of an 11th-century woman in rural Germany. “Only by looking very closely at new kinds of evidence can we begin to discover the true importance of female artisans,” said Herman.

Are bigger brains smarter? Barely, says study led by Penn scholar
A new study co-led by the Wharton School’s Gideon Nave and the School of Arts and Sciences’ Joseph Kable found that brain size has a slight, but ultimately insignificant, correlation to intelligence.

PGW plan for liquified natural gas facility in Southwest Philadelphia clears hurdle
Christina Simeone of the Kleinman Center for Energy Policy discussed the possible environmental impact of the creation of a new liquified natural gas (LNG) facility in Southwest Philadelphia. “The environmental benefit will happen if LNG displaces diesel or fuel oil,” she said. “But it’s just not clear until there’s a client base who is going to be the end user of this gas.”

After a stressful election, experts warn blockchain is not the answer
Matt Blaze of the School of Engineering and Applied Science weighed in on blockchain voting. “The charlatans pushing for blockchain elections and online voting are doing the equivalent of advocating a healthcare policy that assumes we’re about to cure cancer,” Blaze tweeted. “Maybe we will, but best not to bet on it.”
