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.
With a tag, an anchor and a cage that can be unlocked with light, chemists have devised a simple, modular system that can locate proteins at the membrane of a cell.
Astronomers have expanded the search for extraterrestrial intelligence into a new realm with detectors tuned to infrared light. Their new instrument has just begun to scour the sky for messages from other worlds.
Nearly every cell in our bodies carries the same genetic code. Yet different types of cells read the same DNA in widely different ways, influenced by chemical chemical tags that modify the genetic material without changing the underlying DNA sequence. Scientists today announced significant progress in…
Two UC San Diego astrophysicists together with a colleague at Columbia University have been awarded a 2014 Buchalter Cosmology Prize for a paper proposing a way to significantly enhance cosmological measurements in a way that should enable sensitive tests of ideas fundamental to our understanding of…
When a rapidly-growing cell divides into two smaller cells, what triggers the split? Is it the size the growing cell eventually reaches? Or is the real trigger the time period over which the cell keeps growing ever larger? A novel study published online today in the journal Current Biology has…
A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.
Composite subatomic structures created by powerful collisions of protons have fallen apart in unexpected ways within a detector in the Large Hadron Collider called LHCb.
Marvin L. "Murph" Goldberger, an emeritus professor of physics who was dean of UC San Diego’s Division of Natural Sciences from 1994 to 1999, following a prominent career that included working on the Manhattan Project and serving as the president of Caltech, died Nov. 26 in La Jolla. He was 92.
