Varying Drug Levels in the Body Could Speed the Emergence of Drug-Resistant Bacteria

Strains of bacteria able to resist multiple antibiotics pose a growing threat to public health, yet the means by which resistance quickly emerges aren’t well understood.

Exotic particles, chilled and trapped, form giant matter wave

Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave.

Envelope for an Artificial Cell

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life.

Jim Arnold, Founding Chemist at UC San Diego Dies at 88

James R. Arnold, founding chairman of UC San Diego’s chemistry department and first director of the California Space Institute whose contributions to science spanned the study of cosmic rays to the future of manned space flight, died Friday, January 6. He was 88.

Hints of the Higgs Boson Seen as Trap Set for the Elusive Particle Tightens

Physicists announced today that they may have caught glimpses of the Higgs boson, but the signals they see are not yet robust enough to meet the stringent requirements they have set for announcing an official discovery.

Simple Genetic Circuit Forms Stripes

Many living things have stripes, but the developmental processes that create these and other patterns are complex and difficult to untangle.

Suspects in the quenching of star formation exonerated

Supermassive black holes millions to billions times the mass of our Sun lie at the heart of most, maybe all large galaxies. Some of these power brilliantly luminous, rapidly growing objects called active galactic nuclei that gather and condense enormous quantities of dust, gas and stars.
