Why it matters: All that packaging we've treated as disposable may finally be reborn. Researchers have cracked the code for turning plastic back into the building blocks to make new plastics. It could revolutionize recycling, which studies have shown is broken.
The bleeding edge? Swedish scientists may have found a radical nanotech solution to keep the heart beating when it runs into minor problems when healthcare isn't accessible. A newly developed injectable "heart stimulator" can temporarily correct arrhythmia by using your smartphone as a power source.
Blade Runner Perovskite: Researchers at the Hong Kong University of Science and Technology have developed a novel approach to flexible LED technology. By incorporating perovskite, they successfully created fiber light-emitting diodes, or Fi-LEDs, with enhanced optoelectronic properties.
Sweating Planet: Rising temperatures are transforming vast regions of the planet into unbearably hot environments. While air conditioning is effective at cooling indoor spaces, it is also an enormous drain on energy resources. As a result, scientists are seeking innovative solutions that can provide comparable cooling without consuming excessive energy or resources.
