Penn Study: For Cardiac Stenting Procedures, Wrist Access Offers Cost Saving Benefits Over Groin Access

In the United States, radial artery (wrist) catheterization is performed in the minority of diagnostic angiograms and cardiac stenting procedures despite the benefits it offers to patients in terms of reduced complications and faster mobility after the procedure.

Researchers From Penn, Michigan and Duke Study How Cooperation Can Trump Competition in Monkeys

PHILADELPHIA— Being the top dog — or, in this case, the top gelada monkey — is even better if the alpha male is willing to concede at times to subordinates, according to a study by researchers from the University of Pennsylvania, the University of Michigan and Duke University. Alpha male geladas who allowed subordinate competitors into their group had a longer tenure as leader, resulting in an average of three more offspring each during their lifetimes.

Penn Engineers Convert a Natural Plant Protein Into Drug-delivery Vehicles

PHILADELPHIA — Finding biocompatible carriers that can get drugs to their targets in the body involves significant challenges.  Beyond practical concerns of manufacturing and loading these vehicles, the carriers must work effectively with the drug and be safe to consume. Vesicles, hollow capsules shaped like double-walled bubbles, are ideal candidates, as the body naturally produces similar structures to move chemicals from one place to another. Finding the right molecules to assemble into capsules, however, remains difficult. 

Chasing Storms to Study the Carbon Cycle, Penn’s Hyejung Lee Pursues Research in Puerto Rico

Most visitors to the Caribbean hope that their stay won’t coincide with a major tropical storm. Hyejung Lee hoped for exactly the opposite.

Penn Researchers Improve Living Tissues With 3D Printed Vascular Networks Made From Sugar

PHILADELPHIA — Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient’s own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow. Bioengineers can already make 2D structures out of many kinds of tissue, but one of the major roadblocks to making the jump to 3D is keeping the cells within large structures from suffocating; organs have complicated 3D blood vessel networks that are still impossible to recreate in the laboratory.

George W. Bush to Visit Botswana-UPenn Partnership’s Cervical Cancer Program July 5

PHILADELPHIA  – Former President George W. Bush will visit Gaborone, Botswana, Thursday, July 5, to launch a program that will expand women’s health initiatives in that country.  

SAS prof expands the use of carbon nanotubes

Carbon nanotubes have long intrigued physicists and engineers. Their microscopic size and tremendous strength make them ideal candidates for construction materials, and their conductive properties mean they can be used like wires in tiny electrical devices.

Working Dog Center to open at South Bank this fall

Though the 11th anniversary of the Sept. 11, 2001 terrorist attacks will be a time for somber reflection, the Penn Vet Working Dog Center is using the day to celebrate the opening of a new physical space—located in the South Bank, 3401 Grays Ferry Ave.—for training detection dogs.

Morris Arboretum Commemorates 125th Anniversary

PHILADELPHIA -- This year marks the 125th anniversary of the land purchase for Compton, John and Lydia Morris’ estate that would become the Morris Arboretum.  In 1887, the siblings purchased 26 acres of farmland in Chestnut Hill overlooking the Wissahickon Valley with sweeping views of the surrounding countryside.  Their purchase would become one of the foremost Victorian gardens of its time and would lay the foundation for a grand public garden and educational institution that def
