Silica in waste rice husks used to produce LED light

Scientists in Japan have developed a way to recycle rice husks to create the first silicon quantum dot (SiQD) LED light.This new method transforms agricultural waste - 100 million tons of rice husk waste is produced per year - into light-emitting diodes in a low-cost, environmentally friendly way.

Which dog breeds live the longest and are the best behaved?

Do some dog breeds live longer than others? And does your dog's breed effect its behavior? Yes, and no, according to two new studies. Jack Russell terriers are longest lived, but genetics suggests breed only poorly predicts behavior.
Quick tips to Reducing Waste in the Lab Experiments

Quick tips to Reducing Waste in the Lab Experiments

the environmental impact of lab experiments. Laboratories are resource-intensive spaces. Lab storage spaces are filled with stacks of boxes containing gloves, pipette tips or PCR plates - all used once, and then thrown away. So, what can be done to reduce the environmental impact of lab work?
Finding Better Ways to Recycle Plastics

Finding Better Ways to Recycle Plastics

Chemical recycling methods and the development of novel polymers can have a significant impact on global plastic waste. According to Megan Mohadjer Beromi, PhD, and Paul Chirik, PhD, "the challenges associated with polymer recycling today are rooted in our inability to manage waste on scale."
