Our accomplishments never cease to amaze me. Imagine being a scientist who can detect hidden chemicals with just a simple test. Here’s another hidden gem.
Dr. Betty Harris is a brilliant scientist and inventor known for her work in chemistry. She was born on July 29, 1940, in Louisiana. From a young age, Betty was fascinated by science. She loved to learn how things worked and always asked lots of questions. Her passion for science led her to become a chemist.
By 1961, aged just 19, she had graduated from Southern University in Baton Rouge with a chemistry degree.
She did her research at Los Alamos National Laboratory, New Mexico, where she worked in the areas of hazardous waste treatment and environmental remediation as well as explosives chemistry. Areas of focus included explosives detection, synthesis and characterization of insensitive high explosives and sensitivity of weathered high explosives.
Her invention, a spot test for TATB, represents a significant advancement in the detection of this crucial but stable explosive compound.
TATB stands for 1,3,5-triamino-2,4,6-trinitrobenzene. It’s a type of explosive that is very stable and safe to handle, making it important for various safety applications. TATB is used in explosives because it doesn’t explode easily under heat or shock, which means it’s safer to store and use.
Harris invented a special test called a “spot test” to detect TATB. Before her invention, finding TATB in materials was difficult and time-consuming. Her spot test made it quick and easy to detect this important chemical.
The spot test developed by Harris is a simple yet powerful method that involves a few straightforward steps. A small sample of the material in question is obtained. The sample is treated with a special chemical solution formulated by Harris. If TATB is present in the sample, the solution undergoes a color change, providing a clear and immediate indication of its presence.
Harris’s spot test is important for several reasons. The test helps ensure that explosives are safe to handle and store. By detecting TATB quickly, accidents can be prevented. It is easy to use and provides fast results, saving time and resources.
Inventions like Harris’s help science to progress by making it easier to work with important chemicals.
Her contributions extend beyond her scientific achievements. She is a passionate advocate for education and has been a mentor to countless young scientists, particularly encouraging girls and African American students to pursue careers in Science, Technology, Engineering and Math (STEM) fields.
Her dedication to fostering the next generation of scientists has earned her numerous accolades and respect in the academic community.
Harris still lives in New Mexico.

OPINION: Your Voice and Vote Impact the Quality of Your Health Care
One of the most dangerous developments we’re seeing now? Deep federal cuts are being proposed to Medicaid, the life-saving health insurance program that covers nearly 80 million lower-income individuals nationwide. That is approximately 15 million Californians and about 1 million of the state’s nearly 3 million Black Californians who are at risk of losing their healthcare.

Shortly after last year’s election, I hopped into a Lyft and struck up a conversation with the driver. As we talked, the topic inevitably turned to politics. He confidently told me that he didn’t vote — not because he supported Donald Trump, but because he didn’t like Kamala Harris’ résumé. When I asked what exactly he didn’t like, he couldn’t specifically articulate his dislike or point to anything specific. In his words, he “just didn’t like her résumé.”
That moment really hit hard for me. As a Black woman, I’ve lived through enough election cycles to recognize how often uncertainty, misinformation, or political apathy keep people from voting, especially Black voters whose voices are historically left out of the conversation and whose health, economic security, and opportunities are directly impacted by the individual elected to office, and the legislative branches and political parties that push forth their agenda.
That conversation with the Lyft driver reflects a troubling surge in fear-driven politics across our country. We’ve seen White House executive orders gut federal programs meant to help our most vulnerable populations and policies that systematically exclude or harm Black and underserved communities.
One of the most dangerous developments we’re seeing now? Deep federal cuts are being proposed to Medicaid, the life-saving health insurance program that covers nearly 80 million lower-income individuals nationwide. That is approximately 15 million Californians and about 1 million of the state’s nearly 3 million Black Californians who are at risk of losing their healthcare.
Medicaid, called Medi-Cal in California, doesn’t just cover care. It protects individuals and families from medical debt, keeps rural hospitals open, creates jobs, and helps our communities thrive. Simply put; Medicaid is a lifeline for 1 in 5 Black Americans. For many, it’s the only thing standing between them and a medical emergency they can’t afford, especially with the skyrocketing costs of health care. The proposed cuts mean up to 7.2 million Black Americans could lose their healthcare coverage, making it harder for them to receive timely, life-saving care. Cuts to Medicaid would also result in fewer prenatal visits, delayed cancer screenings, unfilled prescriptions, and closures of community clinics. When healthcare is inaccessible or unaffordable, it doesn’t just harm individuals, it weakens entire communities and widens inequities.
The reality is Black Americans already face disproportionately higher rates of poorer health outcomes. Our life expectancy is nearly five years shorter in comparison to White Americans. Black pregnant people are 3.6 times more likely to die during pregnancy or postpartum than their white counterparts.
These policies don’t happen in a vacuum. They are determined by who holds power and who shows up to vote. Showing up amplifies our voices. Taking action and exercising our right to vote is how we express our power.
I urge you to start today. Call your representatives, on both sides of the aisle, and demand they protect Medicaid (Medi-Cal), the Affordable Care Act (Covered CA), and access to food assistance programs, maternal health resources, mental health services, and protect our basic freedoms and human rights. Stay informed, talk to your neighbors and register to vote.

IN MEMORIAM: Nate Holden, State Senator and Longtime Los Angeles Councilmember, Dies at 95
Los Angeles County Supervisor Janice Hahn described Holden as “a lion” in the State Senate and a force to be reckoned with on the Los Angeles City Council.” Hahn added that she learned a lot working with Holden when she was a new councilmember.

Former Los Angeles City Councilmember Nathaniel “Nate” Holden, a prominent figure in the city’s politics, passed away at the age of 95, his family confirmed on May 7.
Holden, who represented South Los Angeles for 16 years on the City Council and served one term in the California State Senate, was widely regarded as a forceful advocate for his community.
Los Angeles County Supervisor Janice Hahn described Holden as “a lion” in the State Senate and a force to be reckoned with on the Los Angeles City Council.”
Hahn added that she learned a lot working with Holden when she was a new councilmember.
Holden’s journey to political prominence began in the segregated South, where he was born in Macon, Georgia, in 1929. He often recalled the childhood moment when he first heard the governor of Georgia vowing to continue suppressing Black people.
“Doing the best you can for the people. Law and order. Make sure that people’s communities are safe. I did it all,” said Holden, reflecting on his legacy.
Holden is survived by his sons, including former California Assemblymember Chris Holden, who represented a district in Southern California that includes Pasadena and Altadena in Los Angeles County and cities in San Bernardino County.
