Optoacoustic imaging powered by short bursts of continuous wave (CW) lasers can stimulate the emission of ultrasound waves inside an animal or in human subjects. The method can noninvasively capture blood flow and produce ...
Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...
A recently developed technique known as light-sheet fluorescence microscopy has led to many biological discoveries by allowing researchers to create 3-D images of tissue, even live animal embryos, using fluorescent tags. ...
Researchers have fabricated a new kind of air-filled optical fiber bundle that could greatly improve endoscopes used for medical procedures like minimally invasive surgeries or bronchoscopies. The new technology might also ...
An international team of researchers has used an unconventional imaging technique known as ghost imaging to make spectroscopic measurements of a gas molecule. The new approach by scientists at Tampere University of Technology ...
Scientists from ITMO University developed a laser for precise measurement of the distance between the moon and Earth. The short pulse duration and high power of this laser help to reduce errors in determining the distance ...
Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an alternative to the magnetic ...
A new type of pressure sensor based on light could allow the creation of sensitive artificial skins to give robots a better sense of touch, wearable blood-pressure monitors for humans and optically transparent touch screens ...
The basic quanta of light (photon) and sound (phonon) are bosonic particles that largely obey similar rules and are in general very good analogs of one another. Physicists have explored this analogy in recent experimental ...
A newly developed analysis method can detect hydroxyl radicals (OH) with unprecedented sensitivity. Because OH is a critical component in the combustion processes that power most vehicles, the new approach could advance the ...
