Medical Xpress / Smartphone tests spot cognitive decline faster than standard method
People with mild cognitive impairment (MCI) are at higher risk of developing dementia. Indeed, many of them experience a gradual decline in cognitive performance over time. Smartphone- or tablet-based memory tests can capture ...
Phys.org / Mount Etna eruptions reveal carbon dioxide and water can trigger separate explosive paths
The plumbing systems of volcanoes are vast and complex. But they aren't consistent, even in the same volcano. A Cornell-led collaboration found very different mechanisms behind two historic eruptions of Mount Etna in Italy. ...
Medical Xpress / Suicide prevention overlooks products still widely sold and promoted, analysis warns
Governments put up railings and barriers and regulate supplies of certain drugs to prevent people from dying by suicide. But other products associated with fatal self-harm, such as firearms, pesticides and alcohol, remain ...
Phys.org / Freshwater boundary breach deepens as climate and land use amplify extremes
Human activities have significantly altered the freshwater cycle, threatening its ability to support vital climatic and ecological Earth system processes. A new study led by researchers at the University of Eastern Finland ...
Phys.org / Brain removal in Iron Age Scotland burial reveals far-reaching family ties
It is difficult to identify funerary practices in Iron Age (c. 800 BC–AD 43) Britain, as human remains rarely survive. However, evidence is particularly prominent in north-west Scotland, because environmental conditions support ...
Medical Xpress / AI diagnoses brain tumors in minutes instead of weeks
Experts in Heidelberg, Germany, have developed an AI system that can classify brain tumors with unprecedented accuracy using standard microscopic tissue sections. Using digitized standard stains, the system identifies more ...
Phys.org / Birth rates are declining in most of the world—here's why it really matters
Birth rates have been declining worldwide since the peak of the post-Second World War baby boom. Birth rates have now reached below replacement in most of the world, including Australia. Put simply, populations on average ...

Eating when the body is normally asleep appears to desynchronize the circadian clocks of different cell types in the intestines, a UT Southwestern Medical Center study suggests. The findings, published in PNAS, could help ...
Phys.org / Earth's energy imbalance has doubled—here's why that matters
Heat waves across Europe and South Asia have dominated the news recently. But these events are really a surface expression of more fundamental changes affecting our planet: Earth itself is accumulating heat faster than ever ...
Phys.org / Antibiotics drive resistance in waterways—even after they break down
Antibiotics continue to drive resistance in bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first ...
Phys.org / Precision measurement under impact—when the balance itself becomes the object of measurement
How do you take measurements using one of the most sensitive scales in the world? Researchers at TU Wien have demonstrated how the measurement process affects not only the object being measured but also the scale itself, ...
