Strawberries and DNA spark RISE Elementary students' interest in science
NEOSHO, Mo. — At the end of their experiment, RISE Elementary students were pulling out a gooey, stringy substance from their strawberry mush.
'That's not a booger, that's DNA,' Joseph Williams told the students. 'Science is kinda yucky sometimes, but it's fun.'
Williams, an assistant professor of basic sciences and director of assessment and data analytics for Kansas City University Joplin, helped students extract the DNA from strawberries using a couple of different chemical processes.
The 45 first graders used common household items for the experiment, but Williams told them it's similar to the process they do in the lab to extract human DNA. Extracting the DNA is important for research, testing and exploring the living world, he said.
The students mashed up their individual strawberries in a plastic bag. Then using a simple coffee filter and chemical reactions with things like dish soap and salt, they were able to extract DNA from the fruits with a straw.
Students only had to follow two rules — have fun and ask lots of questions.
'The whole idea about science is about curiosity,' Williams said. 'What we see up and down the spectrum of science education is that the skill of curiosity and wonder is the same skill we want to foster here today. The earlier we can see that science is available, it's accessible, and the questions students have are valid, the hope is that it's going to continue on to create another generation of wonderful scientists and physicians.'
First grade teacher Kacie Barratt said RISE Elementary — Reaching and Inspiring through STEAM Education — focuses on hands-on activities, including bringing in special guests and field trips to spark students' curiosity in science.
While DNA is an advanced concept for her class, students were excited to learn Wednesday and were engaged the entire time, she said. Barratt has a student who can be a bit reserved, but the experiment opened his world to new things.
'His quote was, 'Now this is the science I'm talking about,' Barratt said. 'I asked him if he wanted to be a doctor, and he said no, he wanted to be a scientist. He has been on cloud nine all this afternoon, he can't quit talking about the DNA. This meets kids where they are and also ignites something in their brains.'
First grader Bregan Burch said she had fun learning what DNA stands for, what it is and where it can be found, especially in the strawberries they used Wednesday.
'We watched it when we put it in the cup, and some people were being funny and smelling it,' Burch said. 'When we were watching it, the DNA popped up quick. When I got it in my bag, it didn't really look like what I thought it would look like. It was really gooey.'
Burch isn't quite sure if she wants to be a scientist but maybe wants to work with animals such as dolphins, jellyfish and sea otters. Those animals all have DNA in them, she noted.
Williams hoped his presentation sparked students' interest in medicine and science, and that starts with the makeup of the world around them. He wanted students to understand that DNA is inside of them and makes up all the living matter.
'When they start to see that all life, whether that's human life or a bug or a tree, it all comes back to these basic biochemical structures that whenever they're out on the playground they can start to explore and stay curious about,' Williams said.
The earlier they engage students with these concepts, the better, Williams continued.
'Curiosity and love and compassion are such foundational things of the human experience,' Williams said. 'It's almost one of those things that the earlier we see students, those things haven't had the chance to be deconditioned at times. While we want to help build knowledge, we want to keep that curiosity as well.'
At the end of the afternoon, Barratt thanked Williams for giving the students an experience they'll never forget.
'It's important so they know there's all kinds of options out there for them, there are all kinds of careers,' Barratt said. 'The world is so big. It opens their eyes to new adventures they can go on. This is a memory that will last a lifetime.'

Tree of Knowledge: Fairmont State receives Division of Forestry grant for planting project
Jun. 11—FAIRMONT — Don't call it "landscaping." Fairmont State University last week received a grant from the West Virginia Division of Forestry, which it will use for a tree-planting project on its Locust Avenue campus — but the motivation, participants say, has roots going way deeper. "The trees themselves are a great project, " architecture major Ryan Williams said. They include the American Holly, Eastern Rosebud, Common Witch Hazel trees, all of which are native to north-central West Virginia, and all planted near the dormitories that line the Campus Drive East entrances, which are currently devoid of greenery. "But even more than that, I hope it will inspire more students to get involved, " continued Williams, who is on the school's Creative Sustainability Council and helped secure the Community EquiTree grant through the forestry division. "The more people are engaged with their community and campus, " the student said of the project expected to be completed at month's end, "the more we can better serve." And the best way to engage and serve, Williams continued, is by celebrating nature, which is perpetually blooming, growing and evolving. Such celebration, the student said, happens whether we realize it or not. For many, the academic family tree goes back 41 years to 1984, when celebrated biologist and naturalist Edmund O. Wilson wrote and published a slim book he titled, "Biophilia " — or literally, "love of life." "Life, " in the case of Fairmont State, being what happens on the other side of the classroom wall. Humans, inherently — and unconsciously, even — just "feel " better in the presence of greenery and trees in places they may not normally be found, the naturalist surmised. Especially, he said, in cities and other locales where concrete, neon and gray buildings prevail. College campuses, too. At the height of the pandemic five years ago, with its student population sequestered under quarantine, Fairmont State did a nod to Wilson. The university created Falcon Park, a walking trail which takes in 7.9 wooded acres at the top of campus and is a haven for native birds, turtles and butterflies. Falcon Park has since been recognized by the National Wildlife Federation. Meanwhile, the most recent tree project, said Devin Carpenter, an assistant construction manager at Fairmont State, will be enjoyed for future generations — aesthetically and environmentally. As the trees grow, he said, their root systems will stabilize hillsides, preventing soil erosion. Their canopies will shade asphalt during the hottest days of summer. And their fall foliage will add to the beauty of campus, Carpenter said. "And they offer back to nature a piece of what urban development once removed, " he said.

Doctors Report the First Pregnancy Using a New AI Procedure
Doctors at Columbia University Fertility Center have reported what they are calling the first pregnancy using a new AI system, in a couple that had been trying to start a family for nearly two decades. The pregnancy was possible due to an advance developed by the Columbia team, led by Dr. Zev Williams, director of the center, to address azoospermia, or a lack of detectable sperm in the ejaculate. Male factors account for about 40% of infertility in the U.S., and azoospermia is responsible for about 10% of those cases. Until recently, there was little doctors could do to address the lack of sperm needed to fertilize an egg, other than using donor sperm. While to the naked eye, a sperm sample from a man with azoospermia might look normal, the microscope tells a different story, Williams says. Highly trained technicians rarely find any sperm in these samples, which are often filled with other debris. Add to that the fact that sperm are the smallest cell in the body, and it's not surprising that even the best fertility technicians rarely find sperm in azoospermia samples. That's where AI comes in. Williams and his team spent five years developing a system that combined an AI algorithm for detecting sperm with a fluidic chip that passed the semen sample through a tiny tubule on a plastic chip. If the AI picked up sperm, that tiny portion of semen would be directed to a separate tubule and collected. The few sperm isolated in this way could then be stored, frozen, or used to fertilize an egg. Called STAR, for Sperm Track and Recovery, the system was inspired by similar approaches that astrophysicists use to enlist AI to detect new stars and planets. 'If you can look into a sky that's filled with billions of stars and try to find a new one, or the birth of a new star, then maybe we can use that same approach to look through billions of cells and try to find that one specific one we are looking for,' says Williams. In this case, STAR is trained to pick up 'really, really, really rare sperm,' he says. 'I liken it to finding a needle hidden within a thousand haystacks. But it can do that in a couple of hours—and so gently that the sperm that we recover can be used to fertilize an egg.' Read More: IVF Patients Say a Test Caused Them to Discard Embryos. Now They're Suing STAR is distinct from AI systems that have been developed to scan and detect specific features, Williams says, because it combines that analysis with the ability to also actively isolate the target in question—in this case, any sperm found in a semen sample. The system can scan eight million images in about an hour, and Williams remembers the moment when he was convinced that STAR could become a powerful tool for treating certain forms of infertility. 'To test the system, before we discarded samples where embryologists could not find any sperm, we decided to run those samples through the system. The embryologists really worked hard to find sperm, since they didn't want to be outshone by a machine. In one of the samples they analyzed for two days and found no sperm, STAR found 44 in an hour.' Rosie and her husband became the first couple to get pregnant using STAR in March 2025. The couple spent nearly 19 years trying to get pregnant, and Rosie—who asked to use a pseudonym to protect her privacy—says their Orthodox Jewish faith kept them hopeful during 15 unsuccessful IVF cycles. Prior to the pregnancy, they had explored multiple options to address her husband's azoospermia, including surgery and enlisting an expert from overseas to manually analyze and isolate sperm from his samples. They also researched efforts to extract sperm that were more controversial because they involved using chemicals that could potentially be detrimental to the quality of sperm. 'There really was nothing else out there,' says Rosie, 38, of their options before learning about STAR. 'Especially because I am running quite a few years ahead of where we should be [for fertility]. I'm not that old, but in fertility years—egg-wise—I was reaching my end.' They were introduced to Williams and his fertility program through a community group and learned everything they could about the system. 'We knew exactly what it was, and knew what they were trying to do,' says Rosie. 'If they could get sperm in a more natural way without chemicals and hopefully chose the good ones—if the program was able to do that, we knew we had a better chance.' Read More: Why It's So Hard to Have Your Fertility Tested For the couple, using STAR did not require any additional testing or procedures; their successful cycle in March proceeded no differently than any of the other IVF cycles they had experienced. 'We were keeping our hopes to a minimum after so many disappointments,' says Rosie. 'We came in, did what we had to do for the cycle, knowing there was probably a very small chance of anything happening. Why should this be any different from every other time?' Usually in an IVF cycle, there are far more sperm than eggs, says Williams, but in cases of azoospermia, the opposite is true. So to ensure that a couple has the best chance of a pregnancy, Williams and his team collect several batches of sperm using STAR and freeze them. Then they coordinate the mother-to-be's ovulation cycle on IVF, and on the day they retrieve her eggs, they collect a fresh semen sample, run it through STAR, and use any sperm collected to fertilize any available eggs. The frozen sperm serve as backup in case no fresh sperm can be found. Within two hours after collecting her husband's sperm that March, they learned that Rosie's eggs had been successfully fertilized and were ready to be transferred to her uterus a few days later. 'After the transfer, it took me two days to believe I was actually pregnant,' says Rosie. Now four months along, Rosie is receiving standard obstetric care, and all indications are that her pregnancy is proceeding well. 'I still wake up in the morning and can't believe if this is true or not,' she says. 'And I still don't believe [I'm pregnant] until I see the scans.' Williams says azoospermia is only one of many infertility issues that AI could address. 'There are things going on that we are blind to right now. But with the introduction of AI, we are being shown what those things are. The dream is to develop technologies so that those who are told 'you have no chance of being able to have a child' can now go on to have healthy children.' Contact us at letters@
