The 2023 Nobel Prize in Chemistry was focused on quantum dots – objects so tiny, they’re controlled by the strange and complex rules of quantum physics. Many quantum dots used in electronics are made from toxic substances, but their nontoxic counterparts are now being developed and explored for uses in medicine and in the environment. One team of researchers is focusing on carbon- and sulfur-based quantum dots, using them to create safer invisible inks and to help decontaminate water supplies.

The researchers will present their results today at the spring meeting of the American Chemical Society (ACS).

Quantum dots are synthetic nanometer-scale semiconduc...

Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.

In our rapidly industrialized world, the quest for sustainable materials has never been more urgent. Plastics, ubiquitous in daily life, pose significant environmental challenges, primarily due to their fossil fuel origins and problematic disposal.

Now, a study led by Jeremy Luterbacher’s team at EPFL unveils a pioneering approach to producing high-performance plastics from renewable resources.

The research, published in Nature Sustainability, introduces a novel method for creating...

With more of us looking for alternatives to eating animals, new research has found a surprising environmentally friendly source of protein – algae.

The University of Exeter study has been published in The Journal of Nutrition and is the first of its kind to demonstrate that the ingestion of two of the most commercially available algal species are rich in protein which supports muscle remodeling in young healthy adults. Their findings suggest that algae may be an interesting and sustainable alternative to animal-derived protein with respect to maintaining and building muscle.

Researcher Ino Van Der Heijden from the University of Exeter said: “Our work has shown algae could become part of a secure and sustainable food future...

Barley seedlings grow on average 50% more when their root system is stimulated electrically through a new cultivation substrate. In a study published in the journal PNAS, researchers from Linköping University have developed an electrically conductive “soil” for soilless cultivation, known as hydroponics.

“The world population is increasing, and we also have climate change. So it’s clear that we won’t be able to cover the food demands of the planet with only the already existing agricultural methods...
