 C. elegans head/upper body of two C. elegans worms, with protein aggregates visible in the pharynx in control conditions (shown by yellow fluorescence, left) and without aggregates due to protein clearance by the SAPA mechanism (right photo).

Tissue-Specific Protein Aggregation Protection Uncovered

Researchers have identified a backup mechanism of protein quality control which prevents the toxic effects of protein aggregation in specific tissues when normal methods of molecular monitoring fail.

Understanding Bacteria on an Individual Level

Recently, scientists have begun leveraging next-generation sequencing and associated techniques, such as single-cell RNA sequencing, that researchers can use to study gene expression in hundreds of thousands of individual cells simultaneously.

Air Pollution Tested on the Wing by Lab-on-a-Drone

Researchers have developed a "lab-on-a-drone" that can detect and analyze pollutants, such as hydrogen sulfide, while on the wing.

A Novel Principle for Nitric Oxide-Mediated Signaling in Blood Vessels

Although a simple molecule, nitric oxide is an important signal substance that helps to reduce blood pressure by relaxing the blood vessels. Researchers now present a novel principle that challenges the previous hypothesis.

Environmental DNA Reveals Diversity of Invasive Fish

Ecologists have demonstrated that the genetic material that species shed into their environments can reveal not only the presence of the species but also a broad range of information about the genetics of whole populations.
