Penn-led Research Elucidates Genetics Behind Salmonella’s Host Specificity
It’s called bird flu for a reason. Particular characteristics about the influenza virus known as H5N1 allow it to primarily affect avifauna, though in some worrying cases the disease has been passed to humans.
Penn Study Blocks Ebola Virus Budding by Regulating Calcium Signaling
The Ebola virus acts fast. The course of infection, from exposure to recovery, or death, can take as little as two weeks. That may not leave enough time for the immune system to mount an effective response.
Study of birds takes flight at Penn
Students in Mike McGraw’s course spend time learning cold, hard facts in the classroom. But they also spend time in less traditional settings.
Penn Dental Medicine Study Shows How Stem Cell Therapy Protects Bone in Lupus
People with lupus, an autoimmune disease, suffer from fatigue, joint pain and swelling and also have a markedly increased risk of developing osteoporosis. Clinical trials have shown that receiving a transplant of mesenchymal stem cells can greatly improve the condition of lupus patients, yet it has not been clear why this treatment strategy works so well.
Fulbright Scholarship to Bring Penn Dental Medicine Professor Full Circle

Penn: Stressed Dads Affect Offspring Brain Development Through Sperm MicroRNA
More and more, scientists have realized that DNA is not the only way that a parent can pass on traits to their offspring. Events experienced by a parent over a lifetime can also have an impact.
Penn study stops vision loss in a canine model of a severe blinding disease
A team led by the School of Veterinary Medicine and the Scheie Eye Institute at the Perelman School of Medicine has shown that they can cure the canine form of X-linked retinitis pigmentosa (XLRP), a severe blinding disease, over the long term, even when the
Pebbles on Mars Likely Traveled Miles Down a Riverbed
While new evidence suggests that Mars may harbor a tiny amount of liquid water, it exists today as a largely cold and arid planet. Three billion years ago, however, the situation may have been much different.
Plant Hormone ‘Switch’ Unravels Chromatin to Form Flowers, Penn Biologists Find
Because plants cannot pick up and move, they have evolved a plethora of strategies to cope with environmental stresses, whether they bring a harsh spell of drought or a browsing deer.
Pebbles on Mars Likely Traveled Tens of Miles Down a Riverbed, Penn Study Finds
While new evidence suggests that Mars may harbor a tiny amount of liquid water, it exists today as a largely cold and arid planet. Three billion years ago, however, the situation may have been much different.
