Solar farm, for article on U.S. electric grid investment

U.S. announces ‘largest ever’ investment in its electric grid to advance climate goals

A $3.46 billion federal investment is rewiring America’s electric grid, spreading across 58 projects in 44 states to make power more reliable and ready for clean energy. The projects are designed to bring more than 35 gigawatts of new renewable energy online — roughly half the country’s utility-scale solar capacity as of 2022. They’ll also fund 400 microgrids, giving hospitals, neighborhoods, and rural communities a way to keep the lights on when storms take down the main grid. Each project had to direct benefits toward communities historically hit hardest by outages and pollution. For a clean energy future to actually reach everyone, the wires connecting it all matter just as much as the panels and turbines — and this is what modernizing with equity in mind looks like.

Bandage on knee, for article on bioprinted skin

Breakthrough human-like bioprinted skin heals wounds better and faster

Bioprinted skin combining all six primary skin cell types has, for the first time, been successfully grafted onto wounds in pre-clinical trials — closing them faster and with noticeably less scarring. Researchers at Wake Forest layered keratinocytes, fibroblasts, adipocytes, melanocytes, and two other cell types into a three-layer structure mirroring real skin, then watched it grow blood vessels and integrate naturally with surrounding tissue. A larger graft, roughly two inches square, worked on a pig model — a meaningful step toward the kind of scale human patients actually need. For burn survivors and others who simply don’t have enough healthy skin to donate, a lab-grown alternative made from their own cells could transform one of medicine’s most painful, limited tools into something closer to true regeneration.
