Team makes startling discovery in highly efficient, 'thresholdless' laser A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that funnels all its photons into lasing, without any waste. The two new lasers require very low power to operate, an important breakthrough since lasers usually require greater and greater "pump power" to begin...

Stem cells derived from fat have a surprising trick up their sleeves: Encouraged to develop on a stiff surface, they undergo a remarkable transformation toward becoming mature muscle cells. The new research appears in the journal Biomaterials. The new cells remain intact and fused together even when transferred to an extremely stiff, bone-like surface, which has University of California, San Diego bioengineering professor Adam Engler and colleagues intrigued. These cells, they suggest, could...

Who´d have thought Facebook was popular in an ancient Tanzania culture? Well it wasn´t, but the people of the Hadza group exhibited many of the “friending” habits familiar to today´s Facebook users, suggesting that social networking patterns were set early in the history of our species. While ancient humans didn´t have the luxury of updating their social status, social networks were indeed an essential part of their livelihood, say authors of a new study,...

Researchers from North Carolina State University, Sandia National Laboratories, and the University of California, San Diego have developed new technology that uses microneedles to allow doctors to detect real-time chemical changes in the body — and to continuously do so for an extended period of time. “We´ve loaded the hollow channels within microneedles with electrochemical sensors that can be used to detect specific molecules or pH levels,” says Dr. Roger Narayan,...

The lowly and simple roundworm may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow scientists to improve the body's response to healing skin wounds, a serious problem in diabetics and the elderly. That's the conclusion of biologists at the University of California, San Diego who have discovered genes in the laboratory roundworm C. elegans that signal the presence of surface wounds and trigger another series of...

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus. Specifically,...
