A team at Helmholtz Munich and the Technical University of Munich (TUM) has developed a new microscopy technique that can distinguish lipid species in living cells—in particular cholesterol and sphingomyelin—and map them ...
As human-caused climate change continues to raise temperatures across the globe, understanding how birds regulate their temperature is vital for their conservation. But how much heat birds emit—an invisible spectrum of radiation ...
Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its capabilities, photonics comes ...
Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical imaging, but their generation often relies on complex and power-intensive systems ...
After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control electrical currents—are few and far between. But with a pair of published papers, materials engineers at ...
Polypropylene and polyethylene are two durable and affordable plastics commonly used as packaging materials, snack wrappers, microwave containers, and other, usually flexible, plastic films. Their flexibility, however, makes ...
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious ...
When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region of the electromagnetic ...
In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around three years before fading ...
Researchers at Oregon State University have developed and tested in a mouse model a new type of nanoparticle that enables the removal of melanoma tumors with a low-power laser. After the systemically administered nanoparticles ...
