An Icy Journey Gave Penn’s Leah Davidson a Worldly Perspective
Leah Davidson, a sophomore at the University of Pennsylvania, plans to pursue a career in business. But she wants to do so in an environmentally conscientious manner. So when, as a high school senior, she learned of an opportunity to visit one of the most untouched habitats on Earth, she jumped at the chance.
Fruit fly genes reveal strategies to battle Lou Gehrig’s disease
No one fully understands what causes amyotrophic lateral sclerosis (ALS), the illness commonly known as Lou Gehrig’s disease. The ailment typically crops up spontaneously, leading to dysfunction and death of motor neurons, slowly sapping strength until those living with the disease can become entirely paralyzed.
Penn Team Reduces Toxicity Associated With Lou Gehrig’s Disease in Animal Models
Amyotrophic lateral sclerosis, better known as Lou Gehrig’s disease, is a devastating illness that gradually robs sufferers of muscle strength and eventually causes a lethal, full-body paralysis. The only drug available to treat the disease extends life spans by a meager three months on average.
Penn professor tells the history of one of Philly’s most visible, bushy-tailed residents
Etienne Benson, an assistant professor in Penn’s Department of History and Sociology of Science, has trained his academic eye on the history of conservation of large, charismatic wildlife, such as tigers, grizzly bears, and orcas.
Crossing the blood-brain barrier to treat Alzheimer’s
Drugs intended to break apart the tangled plaques that cloud the brains of Alzheimer’s patients confront a biological obstacle: the blood-brain barrier. Tightly packed cells along this border between the brain and the bloodstream allow only small molecules to cross, effectively protecting the brain against pathogens, but stifling many treatment strategies.
Penn Researcher Traces the History of the American Urban Squirrel
Until recently, Etienne Benson, an assistant professor in the University of Pennsylvania’s Department of History and Sociology of Science, has trained his academic eye on the history of conservation of large, charismatic wildlife, such as tigers, grizzly bears and orc
One Protein, Two Personalities: Penn Team Identifies New Mechanism of Cancer Spread
Cancer involves a breakdown of normal cell behavior. Cell reproduction and movement go haywire, causing tumors to grow and spread through the body.
Penn Study Treats Alzheimer’s by Delivering Protein Across Blood-Brain Barrier
The body is structured to ensure that any invading organisms have a tough time reaching the brain, an organ obviously critical to survival. Known as the blood-brain barrier, cells that line the brain and spinal cord are tightly packed, making it difficult for anything besides very small molecules to cross from the bloodstream into the central nervous system.
Five Penn Faculty Earn Distinction as AAAS Fellows
Five faculty members from the University of Pennsylvania have been named fellows of the American Association for the Advancement of Science.
Penn biologists get a flavor for the evolution of bitter taste
A bitter taste may elicit a grimace, and indeed many bitter substances are toxic and should be avoided. Yet some foods and drugs taste bitter but promote or protect health—think broccoli or quinine.
