Manganese: The Magical Element?

by
0 comments

The element manganese is essential for human life. It’s aptly named after the Greek word for magic, and some mysteries surrounding its role in the body still exist today—like how our bodies absorb it, if very high or low levels can cause illness, or how it might play a role in certain diseases.

A graphic showing manganese’s symbol Mn, atomic number 25, and atomic weight 54.938 connected by lines to illustrations of steel railways, a bone, and a drinking can. Manganese steel contains ~13 percent manganese. It’s very strong and used for railways, safes, and prison bars. Manganese is essential for organisms. It’s needed for strong bones, and many enzymes also contain it. Drink cans are made with an alloy of aluminum and manganese, which helps prevent corrosion. Across the bottom of the graphic are the logo for the Royal Society of Chemistry celebrating IYPT 2019, the Compound Interest logo, and #IYPT2019. Manganese is necessary for metabolism, bone formation, antioxidation, and many other important functions in the body. The element is found in strong steel, bones and enzymes, and drink cans.

“I love that you can change the molecular-level structure of a material, then pull it, bend it, or twist it and see firsthand how the molecular changes you introduced influence its stretchiness or bendiness,” says Frank Leibfarth Ph.D., an associate professor of chemistry at the University of North Carolina (UNC) at Chapel Hill. In an interview, Dr. Leibfarth shares with us his scientific journey, his use of chemistry to tackle challenges in human health and sustainability, and his beliefs on what makes a career in science exciting.

“Our main goal is to get elementary students excited to learn about STEM, and for them to see how beautiful and relevant science can be to communities in eastern Montana,” says Amanda Obery, Ph.D., an assistant professor in elementary education at Central Washington University in Ellensburg, Washington. Dr. Obery co-leads the Authentic Community Engagement in Science (ACES) project with Matt Queen, Ph.D., an assistant professor in biological and physical sciences at Montana State University Billings (MSUB).

When she started college, Anne Carpenter, Ph.D., never guessed she’d one day create software for analyzing images of cells that would help identify potential medicines and that thousands of researchers would use. She wasn’t planning to become a computational biologist, or even to focus on science at all, but she’s now an institute scientist and the senior director of the Imaging Platform at the Broad Institute of Massachusetts Institute of Technology (MIT) and Harvard in Cambridge.

Starting Out in Science

Before beginning her undergraduate studies at Purdue University in West Lafayette, Indiana, Dr. Carpenter’s strongest interests were reading and writing. Then, her subjects expanded. “In college, I liked science as much as anything else, and I realized that was unusual, as a lot of other people really struggled with it. I decided to pursue science because I enjoyed it and the field had good job prospects,” she says. Dr. Carpenter majored in biology because she felt it had the “juiciest questions” as well as a direct impact on human health.

Slideshow: Circles of Life

Every year on March 14, many people eat pie in honor of Pi Day. Mathematically speaking, pi (π) is the ratio of a circle’s circumference (the distance around the outside) to its diameter (the length from one side of the circle to the other, straight through the center). That means if you divide the circumference of any circle by its diameter, the solution will always be pi, which is roughly 3.14—hence March 14, or 3/14. But pi is an irrational number, which means that the numbers after the decimal point never end. With the help of computers, mathematicians have determined trillions of digits of pi.

To celebrate Pi Day, check out this slideshow of circular microbes, research organisms, and laboratory tools (while you enjoy your pie, of course!). To explore more scientific photos, videos, and illustrations, visit our image and video gallery.

Launching Biomedical Careers for Students Who Are Deaf and Hard of Hearing

Scientists who are deaf and hard of hearing (DHH) are underrepresented at all career stages, especially at the Ph.D. level. To address this, the Undergraduate Research Training Initiative for Student Enhancement (U-RISE) training program for undergraduates who are deaf and hard of hearing at the Rochester Institute of Technology (RIT) in Rochester, New York, has committed to lifting barriers and increasing DHH representation in science.

Part of RIT’s National Technical Institute for the Deaf (NTID),
the program is now in its fifth year and prepares undergraduate students who are DHH to enter graduate programs through community-building activities, mentored research training, communication access services like interpretation, and much more. We’ve interviewed two RIT U-RISE students and its director to learn how the program supports its trainees.

Innovating Education, Outreach, and Mentorship With Organic Chemist Neil Garg

“An important part of being in science is being in a community,” says Neil Garg, Ph.D., Distinguished Professor and chair of the department of chemistry and biochemistry at the University of California Los Angeles (UCLA). That philosophy has led him to prioritize mentorship, diversity, and inclusion—while maintaining research excellence—as well as re-envisioning what it means to educate students and the public.

Falling in Love With Chemistry

Science was always a part of Dr. Garg’s childhood. He participated in science fairs as a kid but says he did it for the community and not necessarily for the love of science. “When I look back on those projects, they were always with friends—never by myself,” he says. His parents were both scientists and strongly encouraged him to go into medicine, and although he became a premed major at New York University (NYU), he ultimately chose a different path.

The year 2022 marked 50 years since the creation of the NIGMS Human Genetic Cell Repository (HGCR) at the Coriell Institute for Medical Research in Camden, New Jersey. The NIGMS HGCR consists of cell lines and DNA samples with a focus on those from people with rare, heritable diseases. “Many rare diseases now have treatments because of the samples in the NIGMS HGCR,” says Nahid Turan, Ph.D., Coriell’s chief biobanking officer and co-principal investigator of the NIGMS HGCR. She gives the example of a rare disease advocacy group who worked with the NIGMS HGCR to establish a cell line several decades ago. It was used to identify a gene associated with the disease, which aided in the development of five treatments that have received approval from the Food and Drug Administration.

Researchers have also studied NIGMS HGCR’s samples to help advance knowledge of basic biology and genetics, and even to support the development of a vaccine for a deadly virus.
