Why are old habits so hard to break? A new study suggests that over time, our bad habits (such as smoking cigarettes or over eating) become automatic, learned behaviors. Even if we consciously try to put new good intentions into place, those previously learned habits remain stronger in more automatic, unconscious forms of memory.
This research may help explain why when were under stress we fall back into old habits, such as cheating on a new diet after a bad day at work. Stress can weaken our control over memory and behavior, so that those automatic, habitual responses from the past become more influential. With control weakened, those automatic responses - such as eating a cookie or smoking a cigarette - can override our new good intentions.
Aging can also erode aspects of memory that require control while leaving more automatic, learned behavior preserved. The new research suggests that new learning requires control, whereas past habits are relatively automatic. This may help explain why it can be so hard for older adults to "learn new tricks" and maintain them over time.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
