The body is pretty good at repairing itself, but some parts of our anatomy struggle to bounce back after an injury.

One such material is cartilage – the spongy yet firm connective tissue that keeps our bones from rubbing and jarring against each other. Over time, the translucent or ‘hyaline’ components of cartilage can become heavily degraded, resulting in painful conditions like osteoarthritis and chondromalacia.

Scientists have been working on a way to regenerate hyaline cartilage for years, and now a team led by Northwestern University in the US has achieved a breakthrough. They have developed a biomaterial that, injected into damaged cartilage in living sheep, acted as a scaffold that promoted cartilage regrowth in active joints.

Helical foldamers are a class of artificial molecules that fold into well-defined helical structures like helices found in proteins and nucleic acids. They have garnered considerable attention as stimuli-responsive switchable molecules, tuneable chiral materials, and cooperative supramolecular systems due to their chiral and conformational switching properties.

Double-helical foldamers exhibit not only even stronger chiral properties but also unique properties, such as the transcription of chiral information from one chiral strand to another without chiral properties, enabling potential applications in higher-order structural control related to replication, like nucleic acids.

However, the artificial control of the chiral switching properties of such artificial molecules remains challenging due to the difficulty in balancing the dynamic properties required for switching and stability. Although various helical molecules have been developed in the past, reversal of twist direction in double-helix molecules and supramolecules has rarely been reported.

The allure of AI companions is hard to resist. Here’s how innovation in regulation can help protect people.

The Air Force Research Lab is working with the Space Warfighting Analysis Center and the Defense Innovation Unit to test space data transport concepts.

A groundbreaking study using sub-daily GPS has improved our understanding of early afterslip following earthquakes, offering a more accurate assessment of seismic hazards and enhancing emergency response and preparedness strategies.

A groundbreaking study has revealed new insights into the Earth’s crust’s immediate behavior following earthquakes. Researchers have utilized sub-daily Global Positioning System (GPS) solutions to accurately measure the spatial and temporal evolution of early afterslip following the 2010 Mw 8.8 Maule earthquake. This innovative approach marks a significant advancement in seismic analysis, offering a more precise and rapid depiction of ground deformations, which is essential for assessing seismic hazards and understanding fault line activities.

The aftermath of an earthquake is marked by intricate postseismic adjustments, particularly the elusive early afterslip. Daily seismic monitoring has struggled to capture the rapid and complex ground movements occurring in the critical hours post-quake. The intricacies of these initial activities and their profound implications for seismic hazard assessment highlight an urgent need for more refined and immediate monitoring techniques.
