New imaging technology could help predict heart attacks

Researchers have developed a new intravascular imaging technique that could one day be used to detect coronary plaques that are likely to lead to a heart attack. Heart attacks are often triggered when an unstable plaque ruptures ...

An ultra-degree-of-freedom structured vector beam

Optics Express recently published research demonstrating a laser that is able to produce a new type of vector beam. This so-called vector-ray-wave beam with 5 degrees of freedom breaks the paradigm of the conventional vector ...

New optical method paves way to breath test for cancer biomarker

Researchers have developed an extremely sensitive, yet simple optical method for detecting formaldehyde in a person's breath. Because formaldehyde is being studied as a potential biomarker for lung and breast cancer, the ...

Scientists create the first diamond X-ray micro lens

After fourth-generation synchrotrons were invented (these are particle accelerators, which are, in fact, giant research facilities), there was an urgent need for a fundamentally new optics that could withstand high temperatures ...

Exploring tiny forces with single molecule force spectroscopy

In terms of space organization, DNA has powers rivaling Marie Kondo. A strand of DNA that is two meters long intricately folds itself into a cell nucleus only 10 microns across. (One of the hairs on your head has a diameter ...
