Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid — in this case, the flow of air over the wings — becomes chaotic and unstable. For more than a century, the field of fluid mechanics has posited that turbulence scales with inertia, and so massive things, like planes, have an easier time causing it.

Deep brain stimulation (DBS) in a precise region of the brain appears to reduce caloric intake and prompt weight loss in obese animal models, according to a new study led by researchers at the University of Pennsylvania.

It was 3 a.m. at an engineering camp in Houston when insight struck Allison Pearce, now a junior at the University of Pennsylvania.

A dye-based imaging technique known as two-photon microscopy can produce pictures of active neural structures in much finer detail than functional magnetic resonance imaging, or fMRI, but it requires powerful and expensive lasers.

A gene therapy study focused on finding a cure for a rare congenital blinding disease has been recognized as one of the ten most outstanding clinical research projects of the year by the Clinical Research Forum (CRF). The study, led by Jean Bennett, MD, Phd, F.M.

“Well-rounded” just doesn’t seem to cover it.  Nor does “always busy.” Andrew Dierkes, 19, is a sophomore at the University of Pennsylvania, but, he’s no ordinary undergraduate.

A new study from the University of Pennsylvania has shown that children as young as 2 understand basic grammar rules when they first learn to speak and are not simply imitating adults.

A research team including members of the Department of Bioengineering in the University of Pennsylvania School of Engineering and Applied Science has discovered that drug intervention to reduce intercellular signaling between astrocytes following traumatic brain injury reduces cognitive deficits and damage.

The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body’s different cell types. But clinical applications in the field have been slow to materialize, partially owing to difficulties in replicating the conditions these cells naturally experience.

Like animals, plants go through several stages of development before they reach maturity. It has long been thought that some of the transitions between these stages are triggered by changes in the nutritional status of the plant.
