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 / 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 / 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 / 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 / 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 / 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 / Extracellular vesicles manage to slip gene edits into Pneumocystis fungi
Pneumocystis is an unwieldy genus of fungal pathogens that cause severe pneumonia, particularly in immunocompromised people like those with HIV/AIDs or who have received organ transplants. However, the mechanisms by which ...
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 ...
Phys.org / Cells' built-in capacity limit for copying DNA could impact cancer treatment
For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides, which happens constantly. Without this process, we would die. These essential, ongoing ...
Phys.org / Atlantic nurse sharks show faster growth patterns in Biscayne Bay than nearby Bimini, Bahamas
A new study from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science shows that juvenile Atlantic nurse sharks (Ginglymostoma cirratum) grow more rapidly as juveniles and reach smaller maximum ...
