New research by the University of Portsmouth reveals that during the Great Plague of 1665, Londoners used published death figures to make daily, life or death decisions, reshaping how governments managed public health and ...
Phys.org / Could the discovery of a tiny RNA molecule explain the origins of life?
One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen polar ice to superheated ...
Phys.org / Study uncovers hidden psychology behind a 'good kiss'
New research from Abertay University published on Valentine's Day reveals that what makes a "good kiss" has far more to do with our imagination and internal emotional world than the physical act itself. Published in the journal ...

The Canadian government's recent approval of the first gene-edited animal to enter the food system has reignited debates over whether foods produced using genetic engineering techniques should be labeled.
Medical Xpress / Hearing loss and cognitive decline in presbycusis may be linked via neural activity fluctuations, cell death
Presbycusis is a prevalent form of age-related hearing loss that also hinders speech recognition. While scientists have linked hearing loss to an increased risk of cognitive decline, the biological "bridge" between the two ...
Medical Xpress / Why you hardly notice your blind spot: New tests pit three theories of consciousness
Although humans' visual perception of the world appears complete, our eyes contain a visual blind spot where the optic nerve connects to the retina. Scientists are still uncertain whether the brain fully compensates for the ...
Medical Xpress / Fast, simple method can detect key immunity biomarker in blood
Researchers at St. Petersburg University have developed an efficient way to detect a crucial immunity biomarker—neopterin—in the blood using nanotechnology and a laser. Neopterin is a nucleotide whose blood levels rise ...
