Electrical engineers build 'no-waste' laser

Tweet

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.

Good timing: NIST/CU collaboration adds timing capability to living cell sensors

Tweet

Individual cells modified to act as sensors using fluorescence are already useful tools in biochemistry, but now they can add good timing to their resumé, thanks in part to expertise from the National Institute of Standards and Technology (NIST).

With the added capability to track the timing of dynamic biochemical reactions, cell sensors become more useful for many studies, such as measurements of protein folding or neural activity.

'Dark plasmons' transmit energy

Tweet

Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers at Rice University.

Research finds ways that young couples experience less relationship stress, higher satisfaction

Tweet

MANHATTAN, KAN. -- The happiest young couples may be involved in a different kind of engagement.

Young adults who easily engage in rewarding conversations with their partners are less likely to hold onto anger and stress and more likely to be satisfied with the relationship, according to research from Kansas State University.

New technology platform for molecule-based electronics

Tweet

Researchers at the Nano-Science Center at the University of Copenhagen have developed a new nano-technology platform for the development of molecule-based electronic components using the wonder material graphene. At the same time, they have solved a problem that has challenged researchers from around world for ten years.

New battery could lead to cheaper, more efficient solar energy

Tweet

A joint research project between the University of Southampton and lithium battery technology company REAPsystems has found that a new type of battery has the potential to improve the efficiency and reduce the cost of solar power.

Study: Some formerly cohabiting couples with children keep romantic relationship

Tweet

COLUMBUS, Ohio – When low-income cohabiting couples with children decide to no longer live together, that doesn't necessarily mean the end of their romantic relationship.

A new study suggests that about one in four of these couples who split their households still maintain some type of romantic relationship.

Amazing skin gives sharks a push

Skin deep

For swimmers looking to gain an edge on the competition, the notion that simply donning a different swimsuit – like a Speedo Fastskin II suit, with a surface purportedly designed to mimic by shark skin – can be the difference between first and last place is a powerful one.

It's also one that's almost completely misplaced, said George Lauder, the Henry Bryant Bigelow Professor of Ichthyology.
