Phys.org / Three nonlinear optical materials achieve sub-200-nm cutoff edges for advanced photonics
Nonlinear optical (NLO) materials play a vital role in modern photonic technology, driving advancements in applications such as laser frequency conversion, ultrafast optical switching, and quantum information processing. ...
Phys.org / Northern lights may be visible in parts of the US due to solar storms
Solar storms may bring colorful auroras to several northern U.S. states Thursday night.
Phys.org / Not-so-model behavior: Popular software tools may give faulty forecasts
Some of the models used to forecast everything from financial trends to animal populations in an ecosystem are incorrect, according to an Idaho State University statistician.
Phys.org / Landscape clues suggest Indigenous Peoples have thrived in southwestern Amazon for more than 1,000 years
In September 2021, a multidisciplinary expedition explored one of the least-known regions of the Bolivian Amazon: the Great Tectonic Lakes of Exaltación in the department of Beni.
Phys.org / Deep-sea mining waste threatens life and foodwebs in the ocean's dim 'twilight zone,' first study of its kind finds
A new study led by researchers at the University of Hawaii (UH) at Mānoa published in Nature Communications is the first of its kind to show that waste discharged from deep-sea mining operations in the Pacific's biodiverse ...
Phys.org / Electrified atomic vapor system enables new nanomaterial mixtures
Vapor-phase synthesis, a technique used to create very pure and scalable nanomaterials and coatings, has great promise for the electronic, optical, aerospace, energy and environment, and semiconductor industries.
Phys.org / In the US, Western rivers may be allies in the fight against climate change
For decades, scientists have generally thought that rivers emit more carbon dioxide, a greenhouse gas, than they take in. But a new analysis of every river network in the contiguous United States—including underrepresented ...
Phys.org / Unraveling water's effect on chitin nanocrystals
Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have used three-dimensional atomic force microscopy (AFM) and molecular dynamics simulations to determine the structure of water in the hydration ...
Phys.org / The enzyme that doesn't act like one: NUDT5 controls DNA building block production through structure, not catalysis
Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that provides vital chemical units ...
Phys.org / New polariton technology could advance thin infrared detectors in various industries
Researchers at the University of Turku, Finland, have developed an organic infrared photodiode that achieves record-level sensitivity in devices that are ultrathin and ready to be integrated into different applications. This ...
Phys.org / Illegal shark fin trade persists despite protections
Despite more than a decade of international efforts to curb the trade of threatened shark species, new research led by FIU marine biologist Diego Cardeñosa and Demian Chapman, director of the Shark and Rays Conservation ...
Phys.org / Creating better tools to read our DNA's hidden instructions
DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated—able to read not only the code itself, but how ...
