AUSTIN, Texas — Researchers at The University of Texas at Austin are building a new type of ventilator made of cheap, widely available materials to help fill the demand created by the spread of COVID-19 for these critical devices that help patients breathe. (more…)
Someone I know was in a minor car crash recently. The car was hit from behind by a driver who was using a cellphone, causing damage to both vehicles, but nobody was hurt. The police were called, and though the officer was told that the driver who caused the crash was using a cellphone, no tickets were issued. The officer left without filing any kind of accident report. (more…)
AUSTIN, Texas — An extremely rare eyeless catfish species previously known to exist only in Mexico has been discovered in Texas.
Dean Hendrickson, curator of ichthyology at The University of Texas at Austin, identified the live fish, discovered in a deep limestone cave at Amistad National Recreation Area near Del Rio, Texas, as the endangered Mexican blindcat (Prietella phreatophila). The pair of small catfish, collected by a team in May, have been relocated to the San Antonio Zoo. (more…)
UD graduate studies soil moisture levels as a geologist in Texas
Even as a little kid, Chelsea Halley knew that she wanted to be a geologist. Now, as the 2012 University of Delaware graduate gets set to receive her master’s degree in geology from the University of Texas, the goal she set when she was younger is becoming a reality as she embarks on a career as a geologist for an environmental consulting company in Austin.

When you do a simple Web search on a topic, the results that pop up aren’t the whole story. The Internet contains a vast trove of information — sometimes called the “Deep Web” — that isn’t indexed by search engines: information that would be useful for tracking criminals, terrorist activities, sex trafficking and the spread of diseases. Scientists could also use it to search for images and data from spacecraft. (more…)
Wechselnde Umweltbedingungen üben einen starken Selektionsdruck auf Arten aus. Im frühen Miozän, vor ca. 18 Mio. Jahren, gab es in Afrika noch keine Savanne, unterschiedliche Lebensräume waren Triebkraft für die Entstehung der Menschenartigen. Auf der Insel Rusinga im Viktoriasee untersucht ein internationales Wissenschaftlerteam unter Beteiligung von Senckenberg-Säugetierspezialist Dr. Thomas Lehmann den Lebensraum einiger der frühesten Menschenartigen. Erstmals konnten die Forscher beweisen, dass diese schwanzlosen Affen wenigstens zeitweise in einem sehr dichten Wald lebten. Die Ergebnisse wurden jetzt im Fachjournal Nature Communications veröffentlicht.
Als die ersten Menschenartigen entstanden und sich ausbreiteten, begann der Ostafrikanische Graben sich zu öffnen. Über Millionen von Jahren hin entstand dadurch zeitgleich eine Vielzahl unterschiedlicher Lebensräume. Da sich ändernde Umweltbedingungen einen starken Selektionsdruck auf Arten ausüben, waren diese variablen Lebensbedingungen auch eine Triebkraft für die Evolution von Affen und Frühmenschen. (more…)
Texas leads the nation in executions. Minnesota has no death penalty. So two researchers—one from the University of Minnesota and one from the University of Texas at Austin (UT Austin)—teamed up to find out something no one had ever looked at before: what the death penalty does for the murder victims’ families. They compared family survivors’ experiences in Texas with Minnesota, the latter one of 18 states with life without the possibility of parole (LWOP) as its “Ultimate Penal Sanction.”
The study used in-person interviews with victims’ families to examine the death penalty process and its long-term impact on the families. (more…)
Significant portions of the Ogallala Aquifer, one of the largest bodies of water in the United States, are at risk of drying up if it continues to be drained at its current rate.
In the current issue of Earth’s Future, a journal of the American Geophysical Union, Michigan State University scientists are proposing alternatives that will halt and hopefully reverse the unsustainable use of water drawdown in the aquifer. The body of water, also known as the High Plains Aquifer, spans from Texas to South Dakota and drives much of the region’s economy. (more…)
