A New UV Laser Sends Messages in Trillionths of a Second

Ultrafast UV-C light just took a leap forward, opening the door to lightning-fast communications and next-generation photonic technologies.

Devices that work with ultraviolet light in the UV-C range (100−280 nm) are becoming increasingly important across many fields, including super-resolution microscopy and optical communications. Scientists are especially interested in UV-C light because it scatters strongly in the atmosphere, a property that makes it useful for non-line-of-sight communication. This means data could be sent even when a clear line of sight is blocked, such as in cluttered or obstructed environments. Despite these advantages, progress has been slow because researchers have lacked practical components that can reliably generate and detect UV-C light.

Identification and Characterization of Alamandine-(1−5), a New Component of the Renin-Angiotensin System

The nitrogenase-like enzyme superfamily.

Nitrogenases are the only enzymes that reduce dinitrogen to ammonia, a reaction essential for all life on Earth.

Recent work demonstrates that nitrogen fixation‐like (Nfl) enzymes have extensive functions beyond nitrogen fixation, including reducing C=C double bonds of tetrapyrroles and breaking C–S bonds to support bacterial sulfur scavenging.

All nitrogenase-like enzymes consist of a reductase component containing an [Fe4S4]-cluster, and a catalytic component containing diverse metalloclusters.

The catalytic components of the nitrogenase-like enzymes contain simpler FeSclusters than nitrogenases, including [Fe4S4]-clusters and nitrogenase cluster precursors. https://sciencemission.com/nitrogenase-like-enzym

Nitrogenases are the only enzymes capable of converting atmospheric nitrogen into bioavailable ammonia, an essential process for all life on Earth. Early ancestors of bona fide nitrogenases and their maturases gave rise to several structural homologues with diverse functions. The nitrogen fixation-like enzyme superfamily comprises ancient metalloproteins involved in elemental processes that range from the biosynthesis of bacteriochlorophyll in bacterial photosynthesis to the biosynthesis of cofactor F430 in archaeal methanogenesis. Recently, new functions of nitrogenase-like enzymes in sulfur scavenging were discovered and have spurred interest due to the simultaneous production of small hydrocarbons.

A New Theory Says Hidden Dimensions May Create Mass. That Would Rewrite Particle Physics

This theoretical explanation could also help explain some of the outstanding questions about the accelerating expansion of the universe. The team explains the possible existence of a particle known as the “torstone,” which would be linked to torsion that could be detected in future experience—if this theory proves out.

Of course, that’s a pretty big if. With the Nobel Prize-winning discovery of the Higgs boson in 2012, the idea of a Higgs scalar field is a strong theory in the standard model. And as with every incredible theoretical idea, this new proposal requires equally incredible evidence. Luckily, scientists are developing ever more-sensitive detectors for probing these very questions. But until scientists can glimpse some semblance of a “torstone,” or other piece pointing to the complicated interaction between higher-dimensional space time and mass, this idea will remain just that—an idea.
