From octopus to elephant: A molecular zoo of epigenetics
Our genes are encoded in the DNA sequence of the genome, which is highly similar across the diverse cell types of our body. Yet, each cell can only access those genes that are in an epigenetically permissive state. The epigenome thus provides a form.....»»
Scientists learn how to drug wily class of disease-causing enzymes
UCSF scientists have discovered how to target a class of molecular switches called GTPases that are involved in a myriad of diseases from Parkinson's to cancer and have long been thought to be "undruggable.".....»»
Hidden, compact galaxies in the distant universe—searching for the secrets behind the little red dots
Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA's most powerful telescope, have found a class of galaxies that challenges even the most skillful creatures in mimicry—like the mimic octopus. This creature can imp.....»»
Researchers develop molecular biosensors that only light up upon binding to their targets
Biosensors—devices that use biological molecules to detect the presence of a target substance—have enormous potential for detecting disease biomarkers, molecules-in-action in diverse biological processes, or toxins and other harmful substances in.....»»
Northern elephant seals use deep-sea research sonar as dinner bell
Northern elephant seals were repeatedly captured on camera in the deep Pacific Ocean using sonar from an Ocean Networks Canada (ONC) observatory as a dinner bell to forage for their next fish feast, according to a new study led by University of Victo.....»»

Controlling molecular electronics with rigid, ladder-like molecules
As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years, according to Moore's law. Molecular elec.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
