Penn: Stressed Dads Affect Offspring Brain Development Through Sperm MicroRNA

blurb: 
University of Pennsylvania researchers have shown at the molecular level how experiencing stress changes a male mouse’s sperm in such a way that it affects his offspring’s response to stress.

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’s Hanson Works to Protect Cultural Heritage Sites in Syria and Iraq

blurb: 
In places like Iraq and Syria, Penn Museum’s Katharyn Hanson teaches locals in the field emergency measures to safeguard culturally important artifacts and sites.

Katharyn Hanson stands on stage at the World Café Live in Philadelphia in front of a crowd of several dozen. Behind her flash images of antiquities and artifacts that make up much of the cultural legacy in places like Syria and Iraq. Sprinkled throughout are photos of explosions, dark gray plumes masking former heritage sites.

Turncoat Protein Regulates Sensitivity of Breast Cancer Cells to Drug, Providing New Target for Preventing Relapses, Finds Penn Study

A surprising, paradoxical relationship between a tumor suppressor molecule and an oncogene may be the key to explaining and working around how breast cancer tumor cells become desensitized to a common cancer drug, found researchers at the

Penn Team Maps First Comprehensive Profile of Non-Protein-Coding RNAs to Provide Clinicians with New Way to Diagnose Array of Cancers

Growing insights about a significant, yet poorly understood, part of the genome – the “dark matter of DNA” -- have fundamentally changed the way scientists approach the study of diseases.

Penn Medicine Researchers Discover Hidden Brain Pathways Crucial to Communication

Being able to understand speech is essential to our evolution as humans. Hearing lets us perceive the same word even when spoken at different speeds or pitches, and also gives us extra sensitivity to unexpected sounds.

Plant Hormone ‘Switch’ Unravels Chromatin to Form Flowers, Penn Biologists Find

blurb: 
University of Pennsylvania researchers have identified a hormone-mediated “chromatin switch” that directs a plant to form flowers. In the absence of auxin, genes that initiate flower formation are tucked away in tangled chromatin, a tightly packed bundle of DNA. But, in the hormone’s presence, proteins are recruited to unravel chromatin and make the genes responsible for flower formation more accessible.

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

blurb: 
In a new report led by University of Pennsylvania geophysicists, they estimate that rounded pebbels on Mars traveled roughly 30 miles from their source, providing additional evidence for the idea that Mars once had an extensive river system, conditions that could support life.

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.

Penn Study Stops Vision Loss in Late-stage Canine X-linked Retinitis Pigmentosa

blurb: 
Three years ago, a team from the University of Pennsylvania announced that they had cured X-linked retinitis pigmentosa, a blinding retinal disease, in dogs. Now they’ve shown that they can cure the canine disease over the long term, even when the treatment is given after half or more of the affected photoreceptor cells have been destroyed.
