A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.

This work presents a soft microelectrode array based on vertically aligned carbon nanotube (CNT) forests, combining high conductivity with mechanical softness. A densification process and air‐pressure‐assisted flexibilization improve structural integrity, ensuring stable insertion and reduced inflammation.

The History of Local Anesthesia
For hundreds of years, mankind has struggled with the problem of controlling pain during surgical procedures without putting the patient to sleep. In 1884, cocaine was discovered to have local anesthetic properties and soon became widely used in many types of surgery. The many undesirable properties of cocaine led scientists to find a safer alternative.

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

Cognitive dysfunction following desflurane versus sevoflurane general anesthesia in elderly patients: a randomized controlled trial. [PDF]
UnlabelledAs life expectancy increases, more patients ≥65 years undergo general anesthesia. Anesthetic agents may contribute to postoperative cognitive dysfunction, and incidence may differ with anesthetic agents or intraoperative anesthesia depth ...

Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

Buckling‐resistant and trace‐stacked (BRATS) intracortical microelectrode arrays (MEAs) eliminate the need for insertion aid and complex surgical setup, resulting in minimal inflammatory tissue response, compared to conventional flexible MEAs inserted with aid. Trace stacking effectively doubled the channel count without increasing the MEA shank width,

This work introduces a novel Hybrid Retinal Implant (HRI), composed of a high‐density electrode array integrated with glutamatergic neurons to overcome key limitations of current retinal prostheses. The significant reduction of activation threshold and of electrode cross‐talk yields in an improved spatial resolution.
