With a beam of infrared light, scientists have sent ripples of electrons along the surface of graphene and demonstrated that they can control the length and height of these oscillations, called plasmons, using a simple electrical circuit.
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.
Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave.
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.
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.
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.
Chemistry lecturer teaches high school students how to power combustion engine using coffee grounds—but hopes they will also learn love for university life
Many living things have stripes, but the developmental processes that create these and other patterns are complex and difficult to untangle.
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.
The last missing piece of scientists’ fundamental model of particle physics is running out of places to hide.
