Deconstructing the mechanics of bone marrow disease
A new understanding of how mechanical features of bone marrow affect resident immune cells in a fibrotic cancer points to future therapeutic strategies for cancers and fibrotic diseases.
Music-making and the flow of aerosols
If simply breathing can spread the SARS-CoV-2 virus to others nearby, what about blowing into a tuba? Researchers from the School of Engineering the School of Arts & Sciences used fluid mechanics to study the movement of aerosols generated by musicians.
In the pursuit of scientific truth, working with adversaries can pay off
The Adversarial Collaboration Project, run by Cory Clark and Philip Tetlock, helps scientists with competing perspectives design joint research that tests both arguments.
The Higgs boson discovery, 10 years later
Penn physicist Elliot Lipeles reflects on the past, present, and future of physics, from the discovery of the Higgs boson to theories about new subatomic particles.
A cleaner, greener airport of the future
Six students from across the University presented their vision of an airport equipped with carbon-capturing technology and an electrified vehicle fleet at a NASA competition, garnering the “Most Intriguing Concept” award.
Shapeshifting microrobots can brush and floss teeth
In a proof-of-concept study, researchers from the School of Dental Medicine and School of Engineering and Applied Science shows that a hands-free system could effectively automate the treatment and removal of tooth-decay-causing bacteria and dental plaque.
The Supreme Court restricts the EPA’s power to curb climate change
Shelley Welton, a new faculty member with Penn Carey Law and the Kleinman Center for Energy Policy, calls the decision “devastating,” even if expected. She explains the ruling and its implications for action on climate change.
Bioengineering technology keeps track of living cells and tissues
A new chemistry technique developed by Jina Ko, assistant bioengineering professor, and colleagues allows for a wider range of fluorescent markers to be added to individual cells without damaging them in the process.
A newly identified stem cell regulator enables lifelong sperm production
Research led by Jeremy Wang of the School of Veterinary Medicine has discovered that the enzyme DOT1L, a stem cell renewal factor, is essential for mice to produce sperm throughout their adult lives.
University of Pennsylvania’s first NFT commemorates mRNA research
Proceeds from the July auction of the non-fungible token—a digital asset—will benefit ongoing research at Penn.
