UNT Makes Strides in Genetic Research with Chemical Mapping

Fri, Mar 31, 2017

By Julia Battle

A student at the University of North Texas completed the first 3D imaging of the inside of Arabidopsis thaliana, a tiny seed that is used for plant research.

Drew Sturtevant, a doctoral student in UNT’s Department of Biological Sciences, used a technology called MALDI-mass spectrometry imagery, which is used to generate chemical heat maps that give researchers an inside look at molecules in a tissue. UNT is one of the few institutions in the...

A Cedar Ridge High School graduate has earned a prestigious scientific honor.

Isabel Delwel, a junior at the University of North Texas, was chosen to participate in the 2017 Howard Hughes Medical Institute Exceptional Research Opportunities Program. One of Delwel’s professor’s, Dr. Lee Hughes, encouraged Delwel to apply for a spot in the program.

Now, she will be one of 67 students from across the United States to participate in the exclusive research opportunity.

The EROP program “aims to ensure that a diverse and highly trained workforce is prepared to assume leadership...

UNT Researcher Studies Pollution, Cardiovascular Disease Link

Fri, Dec 9, 2016

By Nealie Sanchez

Amie Lund, a University of North Texas assistant professor of Biological Sciences, is researching the possible connection between air pollution and deaths due to cardiovascular disease and stroke, according to a UNT news release.

Annually, about 3 million deaths are linked to outdoor air pollution, and Lund is researching the effects of traffic-generated pollution on humans. She found that pollution and higher levels of oxidized “bad” cholesterol in...

UNT Researchers Crack Code of how Plants Form Tannins

Fri, Dec 2, 2016

By Lance Murray

A team of researchers at the University of North Texas’ Department of Biological Sciences has made a major discovery in how plants put tannins together.

Tannins have major human health benefits, and can impact the taste of fruits, and drinks such as tea and wine, according to a release from the university.

The research by Chenggang Liu, Xiaoqiang Wang, Vladimir Shulaev and Richard Dixon, is being featured in the journal, Nature Plants, the university said.

“This is one of the most exciting papers of my career,” Dixon, distinguished research professor...

Bats, bees and the tricky science behind our war on mosquitoes

The letter says it all.

Martha DeLuca of Grand Prairie wrote to The Dallas Morning News in late September, saying her backyard had been full of honeybees, monarch butterflies and hummingbirds. Then, pesticide trucks came to kill mosquitoes.

"This week I have not seen one bird on the feeders, not one honeybee zooming around the garden, dead monarchs lying on the ground, total silence in my garden," DeLuca wrote.

Instead of spraying, she urges natural control, including encouraging mosquito-eating bats to live in neighborhoods.

There is no single way...
