Tracing the radioactive isotopes of heavy elements like uranium 235 – used in nuclear reactors and weapons – is critical to monitor their use and misuse. Michael Gross reports
A silicon device to transform skin tissue into blood vessels and nerve tissue has moved from prototype to standard fabrication. The device, a tissue nanotransfection (TNT) chip, allows DNA or any other charged molecules to be transferred directly into cells to facilitate tissue reprogramming.
Many labs now mimic the protein chemistry used in mussel, oyster and barnacle adhesion in their hunt for glues that are super-strong, non-toxic and that stick under water or inside the body. Emma Davies reports.
Researchers in Japan have proposed an alternative electric energy storage system that uses carbon as an energy source. Their ‘carbon/air secondary battery’ (CASB) comprises a solid-oxide fuel and electrolysis cell where carbon generated via electrolysis of CO2 is oxidised with air to produce energy (J. Power Sources, doi: 10.1016/j.jpowsour.2021.230681).
