The Kjeldahl Method as a Reference Method for Nitrogen and Protein Analysis
An educational video on the Kjeldahl method for determination of Total Kjeldahl Nitrogen (TKN) and crude protein for food and beverage analysis, as well as environmental and pharmaceutical applications.
HPLC Solvent Line Monitor
The Solvent Line Monitor from TESTA Analytical is a valuable addition to any HPLC system. It is designed to detect when one or more of your HPLC pump solvent reservoirs are empty and automatically shut-off the system. This ingenious device continuously monitors the fill status of tubing carrying solvent to up to two HPLC pumps. The device is set-up and controlled using an intuitive PC-based app that provides a simple audible beep or a STOP signal once an ‘solvent empty’ alarm status is detected.
From the OR to the Microbiology Lab: Advanced Development of the MasSpec Pen for Broad Clinical Use
Ambient ionization mass spectrometry techniques that enable direct, gentle, and rapid analysis of samples offer exciting opportunities to provide clinicians with rich molecular data to enhance decision-making. Here, an overview of several ongoing clinical projects in the Eberlin laboratory related to the development of a handheld MS-based device, the MasSpec Pen technology, for improving patient care will be discussed. In particular, I will describe results centered around our efforts in employing the MasSpec Pen for intraoperative tissue analysis and cancer detection, identification of infectious microorganisms, and detection of drugs of abuse.
Mental Illness Not Behind Majority of School Shootings, Study Finds
Researchers analyzing the motivations behind mass school shootings have concluded that in the majority of cases severe mental illness wasn’t a contributing factor.
“Drag-and-Drop” Gene Editing Holds Potential for Treating Genetic Diseases
In a promising development for treating genetic disease, scientists have built upon gene editing technology, creating a novel technique called PASTE to edit large genes safely and more effectively.
Children’s Behavioral Development Is Linked to How You Help Them Sleep
Researchers have discovered that parental methods to help toddlers sleep are related to the development of a child’s temperament.

Making Cancer Medicines With Microbes
For oncology, plant-based anti-cancer drugs have proven instrumental in the fight against a disease that claims approximately 609,360 lives in the United States alone. But their demand far outweighs their supply. Can yeast help?
International Day of LGBTQIA+ People in STEM 2022: An Interview With Dr. Sebastian Groh
Dr. Sebastian Groh identifies as bisexual and transmasculine, “somewhere between non-binary and a trans man”, in his own words. Groh is a research associate at University College London and cofounder of Trans in STEM, and in this interview, we spoke to him to learn more about his research and experiences working in STEM.

Nitrosamine Impurity Analysis Solutions Guide
Since the discovery of elevated levels of nitrosamines in certain pharmaceuticals, reported in July 2018, finding the right solutions have become a major focus for many pharmaceutical manufacturers, particularly as they are considered probable human carcinogens.
Analytical Solutions for mRNA Vaccines and Therapeutics
Messenger RNA (mRNA) therapy enables the body to make the proteins needed to prevent, treat or cure diseases but, unlike traditional biologics, mRNAs are large and delicate molecules that need to be protected by lipid nanoparticles (LNPs) on the journey to reach target cells.
Protein Degradation – A Guide to the Proteasome and Autophagy Systems
The maintenance of proteostasis (the regulation of the proteome) is ensured by complex and interconnected pathways. Impaired proteostasis can lead to the accumulation of damaged or aggregated proteins, or excessive protein degradation.
