Peptides promise to be useful drugs, but they're too easily digested and can’t get into cells without help. Chemists at UC San Diego now show that peptides can be protected from digestion and delivered into cells without changing their biological function by rearranging them into dense brushes.
Chemists have devised a versatile way to attach handles and tags to RNA so that the tiny molecules can be detected and traced within cells or selectively pulled from a complex mixture of molecules.
A simulation that traced the evolution of enormous, bright galaxies over the course of several billion years has illuminated the possible origins of some of the most extreme objects in the universe.
The newly discovered planet orbits a nearby star a lot like our own, though brighter and much younger at just 20 million years old. And the planet is a gas giant, like Jupiter, but hotter and even younger than its star. Because the new planet and its star resemble an earlier version of part of our solar…
Light becomes trapped as it orbits within tiny granules of a crystalline material that has increasingly intrigued physicists, a team led by University of California, San Diego, physics professor Michael Fogler has found.
Scientists have designed nanoparticles that release drugs in the presence of a class of proteins that enable cancers to metastasize. That is, they have engineered a drug delivery system so that the very enzymes that make cancers dangerous could instead guide their destruction.
Physicists have found a way to control the length and strength of waves of atomic motion that have promising potential uses such as fine-scale imaging and the transmission of information within tight spaces.
UC San Diego’s Department of Chemistry and Biochemistry ranked second in the nation in a new survey of professorships held by underrepresented minorities, reflecting the progress we’ve made in building a diverse faculty.
Inspired by the way iridescent bird feathers play with light, scientists have created thin films of material in a wide range of pure colors — from red to green — with hues determined by physical structure rather than pigments.
Synthetic microscopic beads sense changes in their environment and self-propel to migrate upstream, a step toward the realization of biomimetic microsystems with the ability to sense and respond to environmental changes.
