The simple cause of the lily's fan-like shape -- elastic relaxation resulting from bending during differential growth -- was revealed by using an equally simple technique, stretching foam ribbons.

But even the most sophisticated computer cannot match the reasoning of a youngster who looks outside, sees a fresh snowfall, and knows how to bundle up for the frosty outdoors. For artificial intelligence scientists, enabling computers to have such human-level intelligence requires a commonsense knowledge base that can evolve and learn new things. But it's an elusive goal.

Although the first century BC in Italy has been extensively studied, and much is known about the great figures of the era, including Cicero, Caesar, Virgil, and Horace, some basic facts -- such as the approximate population size of the late Roman Republic -- remain the subject of intense debate.

Too much excitement and the network will slip into an apoplectic, uncomprehending chaos. Too much inhibition and it will flatline. A new mathematical model describes how the trillions of interconnections among neurons could maintain a stable but dynamic relationship that leaves the brain sensitive enough to respond to stimulation without veering into a blind seizure.

Researchers also found that low-income children who attended high-quality child care programs before the age of five performed similarly to their affluent peers. These findings have implications for the role of child care in the creation of anti-poverty policies.

The number of learning opportunities a person is exposed to is of great importance to that individual’s cultural evolution during his/her lifetime, according to researchers in Sweden. With the aid of mathematical models, these scientists show that there are differences between cultural and biological evolution.

Hearing aids and cochlear implants act as tiny amplifiers so the deaf and hard-of-hearing can make sense of voices and music. Unfortunately, these devices also amplify background sound, so they're less effective in a noisy environment like a busy workplace or café.
