Where much of the osteoarthritis experienced by more than 32 million Americans is brought on by gradual wear and tear on the joints, some is triggered by injuries to the articular cartilage that covers the ends of the bones. Scientists have developed a… Continue reading Injectable hydrogel could save injured joints from osteoarthritis
Injured cartilage can take the body a long time to repair, but back in 2014 we looked at a promising study where scientists created grafts from nasal cartilage cells and deployed them in damaged knees to help things along. The researchers have since ta… Continue reading How nose cartilage cells are being weaponized against osteoarthritis
Researchers at Washington University School of Medicine have tested an experimental new treatment for rheumatoid arthritis in mice. The team implanted stem cells that have been reprogrammed to secrete anti-inflammatory drugs only when they sense inflam… Continue reading Rheumatoid arthritis implants release drugs when they sense inflammation
Taking inspiration from some of the unique attributes of dragonfly wings, scientists at Germany’s Kiel University have developed a new type of splint for injured joints that offers support in all the right places. The device can withstand loads many ti… Continue reading Dragonfly-inspired splint locks into place to support injured joints
As a degenerative disease that gradually wears away at the joint cartilage and causes great pain for sufferers, scientists are searching far and wide for potential cures for osteoarthritis. For researchers at Pennsylvania State University, that search … Continue reading Anti-depressant found to promote healing in osteoarthritic joints
Human knees are notoriously vulnerable to injury or wearing out with age, often culminating in the need for surgery. Now researchers have created new hybrid bioinks that can be used to 3D print structures to replace damaged cartilage in the knee.Contin… Continue reading Hybrid 3D-printing bioinks help repair damaged knee cartilage
Like most machines, the human body tends to wear out faster at the points of articulation, where decades of stress are focused. Now, researchers at Stanford have found a way to induce cartilage tissue to regenerate in joints by tweaking the stem cells … Continue reading Joint cartilage regrown in arthritic mice by a stem cell tweak
Drawn along in the wake of the 3d printing/home shop revolution has been the accessibility of traditional subtractive CNC equipment, especially routers and mills. Speaking of, want a desktop mill? Try a Bantam Tools (née Othermachine) Desktop Milling Machine or a Carvey or a Carbide 3D Nomad. Tiny but many-axis general purpose mill? Maybe a Pocket NC. Router for the shop? Perhaps a Shapeoko, or an X-Carve, or a ShopBot, or a… you get the picture. The MatchSticks device is a CNC tool for the shop and it might be classified as a milling machine, but it doesn’t quite work …read more

Nobody is likely to confuse it with the beautiful joinery that makes fine furniture so desirable. But as a practical technique, using plastic bottles as heat-shrink tubing for composite joints is pretty nifty, and the pieces produced are not without their charm.
Undertaken as an art project to show people what can be done with recycled materials, [Micaella Pedros]’ project isn’t a hack per se. She started with bottles collected around London and experimented with ways to use them in furniture. The plastic used in soda and water bottles, polyethylene terephthalate (PET), turns out to shrink quite a bit when …read more

Hackaday is primarily a place for electronics hackers, but that’s not to say that we don’t see a fair number of projects where woodworking plays a key role. Magic mirror builds come to mind, as do restorations of antique radios, arcade machines built into coffee tables, and small cases for all manner of electronic and mechanical gadgets. In some of these projects, the woodworking really shines and makes the finished project pop. In others — well, let’s just say that some woodwork looks good from far, but is far from good.
Far be it from me to pass judgment on …read more
