The use of proteins involved in the photosynthetic process enables the development of affordable and efficient devices for energy conversion. However, although proteins such as photosystem I are robust in nature, the use of isolated protein complexes incorporated in semi-artificial electrodes is associated with a considerably short long-term stability. Thus, technological application is still limited. Researchers showed that careful operation of the photosystem-based bioelectrode under the exclusion of oxygen is the key for achieving high stability.
If you believe that great scientists are most creative when they're young, you are missing part of the story. A new study of winners of the Nobel Prize in economics finds that there are two different life cycles of creativity, one that hits some people early in their career and another that more often strikes later in life.
An engineer has created a method to fill in the gaps of available connected vehicle data, which will give transportation planners a more accurate picture of traffic in their cities. It is also a more cost-effective data gathering system than what is currently available.
Scientists have further explored a new effect that enhances their ability to control the direction of electron spin in certain materials. Their discovery may lead to more powerful and energy-efficient materials for information storage.
