Penn and UC Merced Researchers Match Physical and Virtual Atomic Friction Experiments

Technological limitations have made studying friction on the atomic scale difficult, but researchers at the University of Pennsylvania and the University of California, Merced, have now made advances in that quest on two fronts.

Penn Study Identifies Molecular Link Between DNA Damage and Premature Aging

blurb: 
University of Pennsylvania researchers found that inactivating interferon signaling in a mouse model of progeria, or premature aging, extended the animals’ lives.

Like a beloved pair of jeans, human DNA accumulates damage over time, and older people’s bodies can’t repair it as well. Many scientists believe a build up of damage can cause cells to enter an irreversible dormant state known as senescence.

Penn Vet, Montreal and McGill Researchers Show How Blood-Brain Barrier Is Maintained

blurb: 
In a new study, researchers have made insights into how the blood-brain barrier, or BBB, is maintained, identifying a protein key to the process. Delivering this protein to mice with the rodent equivalent of MS improved their symptoms.

The brain is a privileged organ in the body. So vital to life, the brain is protected from alterations elsewhere in the body by a highly regulated gateway known as the blood-brain barrier, which allows only selected molecules to pass through.

Mentally Stepping Back From Problems Helps Youth Deal With Negative Emotions, Penn Study Says

Adolescence is a time of frequent and intense emotional experiences, but some youth handle their emotions better than others. Why do some young people react adaptively while others ruminate?

Penn Senior Adrian Lievano to Tackle Water Security in Kenya

blurb: 
Building prosthetic limbs and developing rain-water filtration systems may seem like they have nothing in common. But to Adrian Lievano, a University of Pennsylvania senior from Miami majoring in mechanical engineering and applied mechanics, there’s a synergy: In both cases, the user is the designer’s top priority.

Penn Researchers Help Make Maps of the Universe’s Dark Matter

blurb: 
Members of the Dark Energy Survey have released the first in a series of maps that show the concentration of dark matter in the cosmos. These maps, created with one of the world’s most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve researchers’ understanding of dark matter’s role in the formation of galaxies.

After the Higgs: Penn Gears Up for New Physics Discoveries at CERN

blurb: 
After a two-year hiatus, the Large Hadron Collider is gearing up for its second run. The LHC enabled the 2012 discovery of the Higgs boson, which gives mass to all particles, but the world’s most complicated scientific apparatus is far from finished

After a two-year hiatus, the Large Hadron Collider at the European Organization for Nuclear Research, or CERN, is gearing up for its second run. The LHC enabled the 2012 discovery of the Higgs boson, which gives mass to all particles, but the world’s most complicated scientific apparatus is far from finished
