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.

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

Penn, Johns Hopkins and UCSB Research: Differences in Neural Activity Change Learning Rate

blurb: 
A new study suggests that recruiting unnecessary parts of the brain for a given task, akin to over-thinking the problem, plays a critical role in the difference between people who pick up a new skill faster or slower.

Why do some people learn a new skill right away, while others only gradually improve? Whatever else may be different about their lives, something must be happening in their brains that captures this variation.

Penn-Rochester Study Identifies a Novel Way to Deliver Drugs to Control Dental Plaque

Therapeutic agents intended to reduce dental plaque and prevent tooth decay are often removed by saliva and the act of swallowing before they can take effect. But a team of researchers has developed a way to keep the drugs from being washed away.
