Polyglycerol coating: A breakthrough in safer nanoparticle environmental remediation      (via sciencedaily.com)     Original source 

Engineered nanoparticles (NPs), commonly utilized in environmental remediation, can pose significant toxicity risks upon ingestion by organisms. Researchers have now devised a solution to this challenge by creating a hydrophilic coating, utilizing polyglycerol (PG) functionalization, for NPs. This coating effectively prevents NP aggregation inside organisms' bodies and facilitates easier passage, thereby reducing accumulation. Applicable to various NPs, the novel surface functionalization approach holds promise for addressing concerns about NP toxicity in environmental remediation.

A simple quantum internet with significant possibilities      (via sciencedaily.com)     Original source 

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.

How to make ubiquitous plastics biodegradable      (via sciencedaily.com)     Original source 

Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process. The plastic can't be broken down by biotechnological means, either. Researchers are looking for ways to rectify this: An international team decoded a bacterial enzyme that plays a key role in styrene degradation. This paves the way for biotechnological application.
