Researchers at Linköping University, Sweden, have developed biosensors that make it possible to monitor sugar levels in real time deep in the plant tissues - something that has previously been impossible. The information from the sensors may help agriculture to adapt production as the world faces climate change. The results have been published in the scientific journal
iScience.
The primary source of nutrition for most of the Earth s population is mainly plants, which are also the foundation of the complete ecosystem on which we all depend. Global population is rising, and rapid climate change is at the same time changing the conditions for crop cultivation and agriculture.

Researchers at Linköping University, Sweden, have developed efficient blue light-emitting diodes based on halide perovskites. We are very excited about this breakthrough , says Feng Gao, professor at Linköping University. The new LEDs may open the way to cheap and energy-efficient illumination.
Illumination is responsible for approximately 20% of global electricity consumption, a figure that could be reduced to 5% if all light sources consisted of light-emitting diodes (LEDs). The blue-white LEDs currently in use, however, need complicated manufacturing methods and are expensive, which makes it more difficult to achieve a global transition.
