BREAKING: ‘This hurts’: UNL eliminates 4 programs despite faculty, student pleas The University of Nebraska-Lincoln eliminates the Earth and atmospheric sciences 8-0, educational administration 7-1, statistics 7-1, textiles, merchandising and fashion design 7-1 programs.

It's over.

Despite the fact that the academic council recommended against it, despite the fact that the program brought in more tuition than it cost, and despite the fact that Nebraskans need & deserve this expertise, Earth & Atmospheric Sciences will be cut.

Occurrence and temporal dynamics of denitrifying protist endosymbionts in the wastewater microbiome Abstract. Effective wastewater treatment is of critical importance for preserving public health and protecting natural environments. Key processes in waste

Protist–bacteria partnerships are more common in wastewater treatment plants than we thought. In this ISME communications paper, we uncovered widespread denitrifying endosymbionts inside ciliates, their global distribution, and their temporal dynamics across WWTPs.🦠

$94.58 billion in NIH funding flowed back into the U.S. economy in 2024. Every dollar boosted jobs, businesses and local communities.

One of the key messages for tomorrow's ASBMB Hill Day is that NIH funding is an economic engine.

Every dollar invested in NIH returns $2.56 to the U.S. economy through jobs, innovation, and commercial activity rooted in NIH driven research.
