Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates. Turning on and off the activity of a single enzyme on demand is a much desired ...

Scientists discovered a key molecular switch to keep neurons healthy by controlling the disassembly and assembly of their ...

A Weill Cornell Medicine team has found that triple-negative breast cancer depends on the enzyme EZH2 to spread. By silencing key genes, EZH2 drives chaotic cell divisions and fuels metastasis.

Steviol glycosides, natural sweeteners extracted from Stevia rebaudiana, are widely used as sucrose substitutes due to their ...

Iridoids are a widespread and evolutionarily ancient class of plant secondary metabolites belonging to the terpenes. They ...

Although putting together the words "random" and "biased" can seem like a clash, these are the attributes that describe how bacteria navigate and fetch their food. They follow a random path, but ...

A new type of assay based on click chemistry will make it possible to carry out high-throughput screens to find inhibitors of the gut hormone ghrelin, a target for obesity and diabetes medications.

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This ...

NIH/Eunice Kennedy Shriver National Institute of Child Health and Human Development Researchers at the National Institutes of Health have discovered that a rare tumor of the adrenal glands appears to ...

New research identifies several existing compounds that block replication of the COVID-19 virus (SARS-CoV-2) within human cells grown in the laboratory. The inhibitors all demonstrated potent chemical ...
