Scientists have developed a novel biosensor based on aptamer-combined surface-enhanced Raman spectroscopy (SERS) to detect inflammatory microRNA-122 (miR-122) in cell-secreted exosomes.

Curved surfaces are found everywhere in biological tissues and evidence suggests that cells are able to sense whether they are in flat or curved environments. A study has now uncovered the mechanisms that regulate the cells’ behavior depending on the change of the environment’s curvature.

Moles and melanomas are both skin tumors that come from the same cell called melanocytes. The difference is that moles are usually harmless, while melanomas are cancerous and often deadly without treatment. A researcher has explained how these skin tumors form and why moles can change into melanoma.

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged.

Scientists are now combining recent advances in evolutionary analysis and deep learning to build three-dimensional models of how most proteins in eukaryotes interact.

Using dark-field microscopy and deep learning, scientists studied microplastics in living cells to help understand what detrimental effects they may be having.

Researchers have linked the T-cell dysfunction seen in rheumatoid arthritis with a metabolic deficiency. The information could help to develop effective treatments.

Prof. Michelle Farkas from the University of Massachusetts Amherst has been awarded a grant by the National Institutes of Health to develop next-generation tools to track and manipulate circadian rhythms in cancer cells.

Researchers say that eliminating old, dysfunctional cells in human fat also alleviates signs of diabetes. This discovery could lead to new treatments for Type 2 diabetes and other metabolic diseases.

Researchers have discovered a way to generate functional cells from stem cells that could open new treatment avenues for people with cystic fibrosis who have liver disease.
