MIT scientists recycle plastic bags to develop a new sustainable fabric
Plastic grocery bags are one of the most pernicious types of plastic waste. Now, scientists say they have developed a technique that could recycle plastic bags into the fabrics of the future. MIT researchers have come up with a method that can transform polyethylene into lightweight fabrics that Read More...
CRISPR technology shows promise in treating rare genetic disease
CRISPR technology has been used to successfully treat sickle cell disease, and now, the CRISPR gene-editing tool has been shown to work safely and effectively when used inside the patient’s body, or 'in vivo,' for the first time. CRISPR conducts cut-and-paste edits to the genome inside cells, Read More...
Artificial intelligence and nanotechnology may help solve world hunger
According to the United Nations, about 840 million people will experience hunger by 2030. This growing global challenge to feed people will only be exacerbated by climate change, increasing populations, and degrading soil quality. Some researchers, however, claim that artificial intelligence and Read More...

Like many other bee cultivators, Beeflow rents out their colonies to farmers to better pollinate the Read More...
How to make flood risk research more equitable
Climate change is exacerbating flood risks in many parts of the world, but unfortunately, research about the impacts of this climate-related flooding is not evenly conducted around the world. Research on flood-vulnerable communities, and subsequent mitigation funding, tends to center on more Read More...
Kazakhstan will become home to the world’s largest green hydrogen plant
Kazakhstan is the ninth biggest — and 18th least densely populated — country on the planet, with just seven people per sq mile. Plus, about a third of the country consists of endless plains of the steppe. All of this means that there’s plenty of land to install renewable energy infrastructure Read More...
This wireless pacemaker dissolves once your body doesn't need it
A team of researchers from Northwestern University has developed a revolutionary temporary pacemaker that is absorbed by the body once it’s no longer needed. Pacemakers are incredible devices that are implanted in patients’ bodies to help regulate their heartbeat. The first pacemaker was Read More...
Dissolving ‘skyscraper’ intends to recover ecosystems destroyed by wildfire
As climate change makes wildfires a more common and severe threat to ecosystems, Italian architect Alberto Roncelli has come up with a design for a dissolving ‘skyscraper’ that would naturally spread nutrients and seeds to ravaged forests — all in a bid to regenerate ecosystems destroyed by Read More...
