Can You Read A Bar Graph?
Bar graphs seem like one of the simplest ways to represent data. Many people assume that the longer the bar, the bigger the number it represents. Sometimes bar graphs represent an average not a total count, which is trickier to understand.
And because bar graphs are everywhere, psychologists from Wellesley College wanted to determine how well people can actually read and interpret bar graphs. Turns out, one in five people in their study misunderstood the data the bar graphs intended to show. And sometimes simple-looking graphs actually make it harder to understand the data they are based on.
Ira talks with Jeremy Wilmer, associate professor, and Sarah Horan Kerns, research associate, at Wellesley College’s department of psychology, based in Wellesley Massachusetts about their bar graph research and curriculum to improve data literacy.
Scientists Release The First Fully Complete Human GenomeTwo decades ago, scientists announced they had sequenced the human genome. What you might not know is that there were gaps in that original sequence—about 8% was completely blank.
Now, after a years-long global collaboration, scientists have finally released the first fully complete assembly of the human genome. Researchers believe these missing pieces might be the key to understanding how DNA varies between people.
Six scientific papers on the topic were published in a special edition of the academic journal Science this week.
Ira talks with Karen Miga and Adam Phillippy, co-founders of the Telomere to Telomere Consortium, an international effort that led to the assembly of this new fully complete human genome.
Karen Miga is an assistant professor of bimolecular engineering and the associate director of the UC Santa Cruz Genomics Institute, based in Santa Cruz California. Adam Phillippy is head of the Genome Informatics Section and senior investigator in the computational and statistical genomics branch at the National Human Genome Research Institute at the National Institutes of Health, based in Bethesda, Maryland.
One Last Martian Love FestAfter a month of non-stop Mars science, what questions do you still have about the Red Planet? SciFri producer Christie Taylor and co-host Stephanie Sendaula interview planetary scientist and Sirens of Mars author Sarah Stewart Johnson. Plus, they take your questions about the planet’s poles, its magnetic field, and the progress of the Perseverance rover.

Why Another Antarctic Ice Shelf Collapsed
On March 15, the Conger ice shelf, a piece of ice half the size of Rome, collapsed in eastern Antarctica. It’s the first time that side of the continent experienced a major loss of ice in the 40-year history of satellite observations. Previous collapses of shelves have until now occurred in western Antarctica. Meanwhile, researchers are reporting temperatures more than 70 degrees Fahrenheit warmer than average, while parts of the Arctic are beating averages by 50 degrees.
Scientific American’s Sophie Bushwick explains why warming at the poles is both more likely than other parts of the globe, and is also exacerbating the likelihood of collapses like this. Plus, new insights into strange radio circles in space, the Hubble telescope sees the most distant star yet, and a look at the statistical likelihood of basketball “hot hands.” And an April Fool’s Day quiz on some new inventions that may or may not be real.
Scientists Are Working On HIV Vaccines Based On COVID Vaccine TechSeveral early Phase 1 human trials of vaccines using mRNA technology are now under way. The approach—which uses mRNA to induce the body to manufacture specific parts of a viral structure that then trains the immune system—was famously successful in the COVID-19 pandemic, and the basis for both the Moderna and Pfizer-BioNTech vaccines.
Now, researchers are wondering if the mRNA approach might be a solution to diseases like HIV, which have thwarted vaccine researchers for years. The NIH has supported three trials, other trials from IAVI and Moderna are also under way in Phase 1.
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, joins Ira to talk about the challenges of developing vaccines against HIV, the path through the clinical trials process, and why researchers are very cautiously optimistic about the new vaccine trials. They also discuss the state of the COVID-19 pandemic, and the need for continued vigilance and funding.
An Oregon Lithium Deposit Could Help Power Clean Energy TechPresident Joe Biden and U.S. lawmakers are ramping up their efforts to mine, manufacture and process more battery materials at home — and that’s drawn praise from the company exploring a large lithium deposit in southeast Oregon. Jindalee Resources Limited, the Australian company with lithium claims at a Bureau of Land Management site in Oregon’s Malheur County, says the growing push for U.S. critical minerals production is a positive sign. “You’ve seen bipartisan support for the development of critical minerals projects growing,” said Lindsay Dudfield, Jindalee’s executive director. “Jindalee is advancing a critical minerals project, and so we’re very encouraged by these developments.”
The Intercept reported Thursday that Biden is preparing to invoke the Defense Production Act to expedite production of batteries for electric vehicles, consumer electronics and renewable energy storage. The Defense Production Act was recently used to increase supply and hasten delivery of COVID-19 vaccines. Lawmakers in recent weeks have urged the president to use his authority under the law to do the same for batteries. “The time is now to grow, support, and encourage investment in the domestic production of graphite, manganese, cobalt, lithium, nickel, and other critical minerals to ensure we support our national security, and to fulfill our need for lithium-ion batteries — both for consumers and for the Department of Defense,” wrote Sens. Lisa Murkowski, R-Alaska; Joe Manchin,D-W.Va.; Jim Risch, R-Idaho; and Bill Cassidy, R-La., in a letter to the president last week. The Biden administration published a report last June that found the American battery supply chain to be extremely vulnerable as demand for batteries increases. For decades, the U.S. has relied on foreign imports of minerals needed to make those batteries, especially lithium.
While the U.S. has large lithium reserves, it only produces about 1% of the world’s supply. Demand for lithium and other materials is expected to skyrocket as the U.S. seeks to transition away from fossil fuels, according to the International Energy Agency. The Biden administration’s report says ...

FDA Convenes Panel On COVID Boosters And New Vaccines
This week, the FDA convened a panel of independent experts to discuss COVID-19 boosters and possible variant-specific vaccines. This comes after last week’s authorization of a second booster for people over the age of 50, and some immunocompromised people.
Ira talks with Maggie Koerth, senior science writer at FiveThirtyEight, based in Minneapolis, Minnesota, about the latest on boosters and other science news of the week, including a new particle measurement that might shift our understanding of physics, fish who can do math and why Mars has two different speeds of sound.
Want To Get Your Spring Garden Going? Here’s Some Expert AdviceIn most parts of the U.S., it’s time to get the garden going for the year. From readying your soil to picking your plants and getting seeds started, April can require a lot of decision-making to set the stage for a successful growing season.
Have questions about choosing containers, hardening your seedlings, or dealing with excess water? Our panel of expert gardeners is here for you. Ira talks to Cornell University Extension’s Elizabeth Buck and Oregon State University Extension’s Weston Miller about common spring troubleshooting, chemical-free pest management, and even how to brace your garden against climate change.
