Phys.org / First direct evidence of Migdal effect opens new path for dark matter search
In a landmark discovery that bridges nearly a century of theoretical physics, a Chinese research team has successfully captured the first direct evidence of the Migdal effect, a breakthrough with profound implications for ...
Phys.org / Increased soil salinity alters global inorganic carbon storage, finds study
A new global study shows that increasing soil salinity is systematically reshaping the storage and distribution of soil inorganic carbon (SIC), a key but often-overlooked part of terrestrial ecosystems. The findings, published ...
Phys.org / Grains of sand prove people—not glaciers—transported Stonehenge rocks
Ask people how Stonehenge was built and you'll hear stories of sledges, ropes, boats and sheer human determination to haul stones from across Britain to Salisbury Plain, in south-west England. Others might mention giants, ...
Medical Xpress / Progenitor cells constantly attempt to produce new myelin-producing brain cells, study finds
In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells—one of the few brain cell types that continue to be produced in the adult brain—undergo differentiation ...
Medical Xpress / Alzheimer's disease can be evaluated with brain stimulation, finds study
As individuals with Alzheimer's disease (AD) move from the mild cognitive impairment stage to moderate and severe dementia, complex awareness deteriorates although lower-level sensory awareness is relatively maintained. Most ...
Phys.org / Catalyst selectivity as a balancing act: Co₃O₄ 'trapped' in transition shows peak activity
In a study appearing in Nature Catalysis, researchers from the Inorganic Chemistry Department of the Fritz Haber Institute reveal how structural changes on the surface and in the bulk region of the cobalt oxide catalyst Co3O4 ...
Phys.org / A twitch in time? Quantum collapse models hint at tiny time fluctuations
Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at once, defined mathematically ...
Medical Xpress / Targeting key proteins in fight against ALS
Northwestern Medicine scientists have zeroed in on a cellular gatekeeper that may hold promise for treating abnormal protein accumulation in neurodegenerative diseases, according to a study published in Nature Communications. ...
Phys.org / Vibrational spectroscopy technique enables nanoscale mapping of molecular orientation at surfaces
Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the micrometer scale by the ...
Phys.org / Nanoscopic raft dynamics on cell membranes successfully visualized for first time
A collaborative team of four professors and several graduate students from the Departments of Chemistry and Biochemical Science and Technology at National Taiwan University, together with the Department of Applied Chemistry ...
Phys.org / Kenya's big cats under pressure: Cattle are pushing lions away
In the Kenyan savanna, lions and livestock essentially live in shifts: Cattle graze during the day and are enclosed at night when lions are active.
Phys.org / Scientists discover a hidden RNA 'aging clock' in human sperm
Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity and stillbirth. But what drives this increased risk remains unknown.
