The Genetics of Epilepsy
Posted in biotech/medical, genetics
Our knowledge of the role of genetics in epilepsy is rapidly expanding, and this is enhancing epilepsy diagnosis, prognosis, and treatment. Julie Ziobro, MD, PhD is a pediatric epileptologist and research scientist at C.S. Mott Children’s Hospital. She and genetic counselor, Mallory Wagner, MS, LCGC, discuss some basic principles of genetics, currently available genetic tests, examples of genetic epilepsies, and how genetic test results can impact treatment decisions and prognosis. They also explore the role of genetics in developing precision therapies for epilepsy.

For ‘deeper reading’ among children aged 10–12, paper trumps screens. What does it mean when schools are going digital?

The Department of Education’s most recent study, declared in June, was surely sensational: it found that text comprehension skills of 13-year-olds had denied an average of four points since the Covid-affected schools in the academic year 2019–2020, and more alarmingly that the average drop was seven points compared with the 2012 figure. The results for the worst-performing students fell below the reading skill level recorded in 1971, when the first national study was conducted.
Hunting for a neutron star
To discover what lies at the center of SN 1987A, astronomers needed a telescope big enough and advanced enough to detect evidence of radiation from a hidden neutron star.
Enter the James Webb Space Telescope: the largest, most powerful telescope ever launched into space that is already revolutionizing our understanding of the universe within its first two years of operation.

Lung cancer is not the most common form of cancer, but it is by far among the deadliest. Despite treatments such as surgery, radiation therapy, and chemotherapy, only about a quarter of all people with the disease will live more than five years after diagnosis, and lung cancer kills more than 1.8 million people worldwide each year, according to the World Health Organization.
To improve the odds for patients with lung cancer, researchers from The University of Texas at Arlington and UT Southwestern Medical Center have pioneered a novel approach to deliver cancer-killing drugs directly into cancer cells.
“Our method uses the patient’s own cellular material as a trojan horse to transport a targeted drug payload directly to the lung cancer cells,” said Kytai T. Nguyen, lead author of a new study on the technique in the journal Bioactive Materials and the Alfred R. and Janet H. Potvin Distinguished Professor in Bioengineering at UTA.
Certain gut bacteria reside in colorectal tumors, but the species differ depending on a patient’s age, offering hope that our gut tenants could serve as early warning signs of cancer in young people.
