Upgrades to the power grid under a new rule could help accommodate an increasing renewable energy supply and meet data center demands. Also, extremely small particles might help scientists develop vaccines that are stable at room temperature and easier to administer.New Rule Sets Stage For Electric Grid UpdateThe US electric grid is straining to keep up with demand. For starters, our warming climate means more electricity is needed to keep people cool. Last summer—which was the hottest on record—energy demand in the US experienced an all-time hourly peak. And even though more renewable energy is being produced, our current grid, largely built in the 1960s and 1970s, was not built to handle those needs. Increased use of AI and cryptocurrency, which require power-hungry data centers, have only increased the burden on the grid.But on Monday, the Federal Energy Regulatory Commission approved new rules to upgrade the grid to accommodate rising demands. The policy includes approval for the construction of new transmission lines and modification of existing transmission facilities.Casey Crownhart, climate reporter for the MIT Technology Review, joins Ira to talk about this and other science stories of the week, including how a recent ocean heatwave will impact ocean life and the upcoming hurricane season, a new self-collection test for cervical cancer, and how a tiny beetle uses audio mimicry to avoid being eaten by bats.Could Vaccines Of The Future Be Made With Nanoparticles?In 2021, vaccines for COVID-19 were released, a little over a year after the SARS-CoV-2 virus triggered a global pandemic. Their remarkably short production time wasn’t the result of a rush-job, but a culmination of decades of advancements in infrastructure, basic science, and mRNA technology.But despite the years of innovations that allowed those vaccines to be developed and mass-produced so quickly, their delivery method—an injection—still has some drawbacks. Most injected vaccines need to be kept cold, and some require multiple trips to a pharmacy. And people with needle phobias may be reluctant to get them altogether. So what could the vaccines of the future look like?Dr. Balaji Narasimhan, distinguished professor and director of the Nanovaccine Institute at Iowa State University, joins Ira Flatow onstage in Ames, Iowa, to talk about how his lab is using nanotechnology to develop the next generation of vaccines, and how they could be more effective than current vaccines in the face of the next pandemic.Transcripts for each segment will be available after the show airs on sciencefriday.com.
