3D printed skin – huge advances could revolutionise wound healing
Two major advances in 3D printing human skin could lead to major advances in wound healing. A team of scientists at Wake Forest Institute for Regenerative Medicine in the US have printed full thickness human skin for the first time. They successfully printed all six major human cell types present in human skin, creating normal skin layers - the epidermis, dermis, and hypodermis. The bioprinted skin formed blood vessels, skin patterns, and showed normal tissue formation. It also produced more collagen which will reduce scarring. If you pay to subscribe to the extended version of the podcast you can hear about another study where the Brazilian cosmetic company Grupo Boticário has 3D printed skin which includes hair follicles.
Stolen mobile phones in Brazil can now be blocked immediately
A new system that blocks stolen mobile phones via an app or the web has been launched in Brazil. Almost a million mobiles were stolen in 2022 in Brazil. Many Brazilians use the instant payment system Pix, so blocking a stolen phone as quickly as possible can significantly reduce the amount money stolen from someone’s account. More than a million people have registered to use the Celular Seguro programme in its first two weeks. Using the country’s citizen registration scheme, it allows people to block or unblock their phones from a trusted and registered source.
The programme is presented by Gareth Mitchell and the studio expert is Angelica Mari.
