Learning about massive open online courses
Over the past five years, massive open online courses (MOOCs) have become an important component of modern education disrupting many conventions and opening up a wide range of new approaches and possibilities. Now, computer scientists explain how expectations are high for what MOOCs can achieve (...)
[Science daily] Toward 'green' paper-thin, flexible electronics
The rapid evolution of gadgets has brought us an impressive array of 'smart' products from phones to tablets, and now watches and glasses. But they still haven't broken free from their rigid form. Now scientists are reporting a new step toward bendable electronics. They have developed the first (...)
[Science daily] Smarter algorithms ensure more secure chip cards
Scientists have succeeded in securing chip cards against leaking confidential information. Through the use of smart algorithms it is now possible to better secure, for instance, bank cards, public transport chip cards and electronic keys of buildings and cars against (...)
[Science daily] Drought-induced tree mortality accelerating in forests
Drought and heat-induced tree mortality is accelerating in many forest biomes as a consequence of a warming climate, researchers report. To predict characteristics of plants that will survive and die during drought in future warmer climates, scientists used Darcy's Law, a core principle of (...)
