Phys.org / Residents from strongly blue or red counties favor like-minded destinations for everyday travel, analysis finds
A new analysis of 471 U.S. counties has found that, for everyday travel, people from counties with particularly strong political leanings—whether liberal or conservative—are more likely to visit like-minded destinations. ...
Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Cryoelectron tomography reveals paracrystalline architecture of proteasome storage granules
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. ...
Phys.org / AI bosses are creating a new problem for gig workers
For millions of gig workers driving for companies such as Uber Eats, DoorDash and Deliveroo, there is no human manager to call, no supervisor to appeal to and no office to walk into. Decisions about pay, performance, penalties ...
Phys.org / Unprecedented 3D views of sensory cells accelerate hearing research
The cochlea is the spiral-shaped structure within the inner ear responsible for our sense of hearing. To fully understand hearing functions and open the door to new hearing loss treatments, scientists require intricately ...
Phys.org / New ABF crystal delivers high-performance vacuum ultraviolet nonlinear optical conversion
Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using nonlinear optical (NLO) crystals ...
Phys.org / Hearing tests uncover unexpected humpback sensitivity to high-frequency noise
University of Queensland hearing tests conducted across kilometers of ocean off the Australian coast show humpback whales react to higher frequency sounds than expected. Associate Professor Rebecca Dunlop from UQ's School ...
Phys.org / How iron-sulfur nanolayers are formed: X-ray methods enable real-time view
Researchers at the University of Hamburg, the University of Toulouse, and the DESY and ESRF research institutes have observed for the first time in real time how iron-sulfur nanostructures form in solutions. Using time-resolved ...
Phys.org / Strength-in-numbers X-ray technique can map previously unattainable atomic structures
For many decades, the method to obtain atomic-level descriptions of chemical compounds and materials—be it a drug, a catalyst, or a commodity chemical—has been X-ray crystallography. This method has a known weakness: ...
Phys.org / Proton-trapping MNene transforms ammonia production for food security and economic growth
With a new electrochemical synthesis via an electrochemical nitrogen reduction reaction (NRR), achieving carbon-free ammonia production is closer to reality through work from Drs. Abdoulaye Djire and Perla Balbuena, chemical ...
Phys.org / Land use acts as a 'silent amplifier' of extreme heat, AI-driven study reveals
A new study using Explainable Artificial Intelligence (XAI) has revealed land-use change—particularly deforestation and unplanned agricultural expansion—is dramatically intensifying heat waves across Africa, with findings ...
Phys.org / Cell surface glycoRNA clusters found to fine-tune growth factor signaling
The recent discovery of glycoRNAs on the cell surface upended the world of cell biology. These glycoRNAs were found to form highly organized clusters with cell surface RNA binding proteins (csRBPs), but their purpose remained ...
