Phys.org / Hummingbirds speed up pineapple family's evolution
Hummingbirds make bromeliad plants split into new species twice as fast as other pollinators do, scientists at the University of Reading have found. The research team gathered records of which animals pollinate 403 types ...
Phys.org / 10 fathers took extended leave to care for their babies—how their family life changed
The UK government launched a major review of parental leave in July 2025, with recommendations expected in early 2027. One question sits at the heart of the review: What difference does parental leave make to family life?
Phys.org / How cells keep genomic hitchhikers under control
Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost their ability to copy themselves into new locations but can still cause problems if they become ...
Medical Xpress / Lower diversity and poorer function of gut bacteria linked to frailty in older women
Researchers at the University of Gothenburg have identified clear links between the composition of gut bacteria and frailty in older women. In cases of high frailty, with an increased risk of illness and death, gut bacterial ...
