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 / 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 / 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 / New fear unlocked: Runaway black holes
Last year, astronomers were fascinated by a runaway asteroid passing through our solar system from somewhere far beyond. It was moving at around 68 kilometers per second, just over double Earth's speed around the sun.
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: ...
Medical Xpress / A neural basis for dumb decisions: Why paying more or waiting in line for an item increases its value in our minds
Ahab hunting down Moby Dick. Wile E. Coyote chasing the Road Runner. Learning Latin. Walking over hot coals. Standing in a long line for boba tea or entrance to a small, overpriced clothing retail store. Forking up for luxury ...
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 / Ultrathin kagome metal hosts robust 3D flat electronic band state
A team of researchers at Monash University has uncovered a powerful new way to engineer exotic quantum states, revealing a robust and tunable three-dimensional flat electronic band in an ultrathin kagome metal, an achievement ...
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 / 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 / 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 ...
Medical Xpress / Interferon signal reprograms macrophage mitochondria to promote inflammation resolution, finds study
When our body fights an infection, the immune system must quickly activate defenses and trigger a beneficial inflammatory response. But it is just as important to resolve that inflammation and return to homeostasis. Macrophages ...
