Research aims to keep drones in the sky for longer

Agencies have come to rely on drones for bridge inspections and search and rescue operations. One of their major drawbacks, however, is the length of time unmanned systems can stay airborne without being recharged.

The Persistent Aerial Reconnaissance and Communications (PARC) drone from CyPhy Works, however, can climb to 400 feet and stay there for up to a week. Because it is tethered to the ground, it can’t range far from base...

On the thawing tundra, researchers race to understand black carbon’s climate impact

On a morning in September 2015, sterile, gray Arctic light filtered through a blanket of woolly clouds as Matt Gunsch and Tate Barrett parked their rented pickup truck on a dirt road and clomped in rubber boots down a long, icy boardwalk to their air-monitoring laboratory on the tundra.

From the outside, the lab looked unglamorous — a dingy, white shack perched on a metal frame in a meadow speckled with snow and grass stubble. It felt distinctly like the middle of nowhere — though it was just a couple of miles beyond the main streets of Utqiaġvik, Alaska, the...

UNT research team analyzing effectiveness of trees

It may not be long before residents of Dallas, Denton, Tarrant and surrounding counties feel the vicious heat of summer and, on certain days, hazy conditions caused by particle pollution in the air. When particulate matter levels in the air are high, anyone sensitive to them may need to limit time spent outdoors, particularly outdoor exercise.

Planting trees in certain urban areas may improve air quality because the trees’ leaves and branches in summer foliage become “urban air filters,” according to Alexandra Ponette-González, University of North Texas assistant professor of geography and the environment.


Breast cancer breakthrough: Spread of disease could be stopped with diabetes drug

Researchers in the US believe the key to fighting the development of a protein associated with the disease could be pioglitazone, a drug typically used to treat type two diabetes by reducing insulin resistance.

They found that reducing the level of the protein NAF-1 and the activity of the iron-sulfur clusters it transports, may be the answer to halting tumour growth.

The team, including scientists from Rice University, Texas, and scientists from Israel, the University of California, San Diego (UCSD) and the University of North Texas, discovered that a single mutation can stop growth.

University of North Texas Students Look For Zika Virus In Mosquitoes

Tue, Sep 13, 2016 - 4:06am

By Bianca Castro

Graduate students at the University of North Texas are at the front lines of the battle against the West Nile virus.

They're testing mosquitoes for the disease that has already affected dozens of North Texans this year and now, they're tracking possible Zika-carrying mosquitoes.

"It's probably a given that Zika is going to get here sometime. No idea when that is going to happen, but it’s already established in Florida and no doubt it’ll do that here," said James...
