It’s no coincidence that the expression “to leave a bitter taste in one’s mouth” has a double meaning; people often have strong negative reactions to bitter substances, which, though found in healthful foods like vegetables, can also signify toxicity. For this reason, the ability to sense bitterness likely played an important role in human evolution.
For solar panels, wringing every drop of energy from as many photons as possible is imperative. This goal has sent chemistry, materials science and electronic engineering researchers on a quest to boost the energy-absorption efficiency of photovoltaic devices, but existing techniques are now running up against limits set by the laws of physics.
An interdisciplinary team of University of Pennsylvania researchers has already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materials, such as nanoparticles.
A third-year student at the University of Pennsylvania Law School, Brittany Strandell, has been selected as the third Alan Lerner Fellowship in Child Welfare Policy recipient.

How do we transform education? Team up.
That’s what researchers and educational leaders from the Barbara and Edward Netter Center for Community Partnerships at the University of Pennsylvania say.
Some people are deeply religious and others not at all. Evolutionary psychologists are interested in determining the functions of religiosity in social life that lead to this diversity.

The Institute of Medicine and the National Research Council today released a comprehensive report on sports-related concussions in youth, detailing factors associated with increased rates of the brain injury, the effectiveness of protective devices and new screening, diagnosis, treatment and management techniques, as well as the long-term consequences of concussions.
Looks do matter, and University of Pennsylvania experts will explain why during a Nov. 2 - 3 conference at Penn's Perelman School of Medicine. Among the participants are Sharrona Pearl from the Annenberg School for Communication and Jesse Taylor from Penn Medicine.
Centuries of economic theory have been based on one simple premise: when given a choice between two items, people make the rational decision and select the one they value more. But as with many simple premises, this one has a flaw in that it is demonstrably untrue.
