Throughout the pandemic, testing has continued to be one of the biggest issues, particularly in the United States. Some scientists say that the solution is to rethink our COVID-19 testing strategy, focusing on making faster, cheaper tests. While these more cost-effective tests may be lower in sensitivity than the PCR tests and perhaps not as accurate, they would allow for more people to get tested and receive faster results. The system can also help improve case tracking—which is essential as more people return to work, school, and daily lives. Eric Topol, the founder and director of the Scripps Research Translational Institute, talks about how these tests can look ahead for infectious patients rather than those already infected. Plus, epidemiologist Anne Wylie walks us through what the process would look like to develop a rapid test.

Plus, we’re back with another installment of the Charismatic Creature Corner! This is Science Friday’s place to highlight creatures (broadly defined) that we think are charismatic (even more broadly defined).

This month, we’re bringing you an ancient ant relative with a possibly offputting name: the Hell Ant. This insect was a subspecies of ants that lived in the Cretaceous period, when T. rexes and velociraptors roamed the earth. The largest hell ants were about a centimeter and a half long, which isn’t much different than some modern ants.

What makes hell ants so cool, however, is their dramatic headgear. They sport jaws that look like mammoth tusks, sticking out of their faces and moving up and down, a motion similar to our own jaws. Hell ants also had horn-like protrusions coming out of their foreheads, which may have helped them catch and eat prey.

SciFri’s new Charismatic Creatures Correspondent Kathleen Davis tries to convince Ira that these extinct insects are worthy of the coveted Charismatic Creature title, with the help of Phil Barden, assistant professor of biology at the New Jersey Institute of Technology in Newark, New Jersey. 

Also, climate activists have struggled to convince lawmakers to meaningfully reduce the country’s carbon footprint. Now, new research ties air pollution’s monetary cost to arguments for change. As Vox reports, a Duke University researcher presented findings to Congress last week that air pollution’s effects are roughly twice as bad as previously thought, potentially costing the United States as much as $700 billion per year in avoidable death, illness, and lost productivity—more than the estimated price tag for transitioning to clean energy.
