Phys.org / Traveling protein waves reveal how dividing cells set chromosome-splitting spindle size
When a human cell prepares to split into two daughter cells, it must first construct a tiny internal machine called the mitotic spindle—a structure of protein fibers that physically pulls chromosomes apart and deposits one ...
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 ...
Phys.org / Researchers uncover the inside story on plant organ growth
Research has shed intriguing new light on the genetics underlying the diverse plant organ shapes seen in agriculture and nature. Despite more than a century of scientific investigation into the role of inner and outer tissues, ...
Phys.org / Bees reveal emotion-like reactions, from 'lip licking' to head shaking, in new videos
New research proving bumblebees exhibit emotion-like behaviors—previously thought to exist only in mammalian species—has implications for how scientists understand the consciousness of insects.
Phys.org / Hotter, drier weather could double water bills in some US cities, study finds
Hotter, drier weather threatens to double water bills by midcentury in some cities, according to a Stanford-led study. The research, published in Nature Sustainability, is the first to comprehensively model how climate change, ...
Phys.org / From The Godfather to Middlemarch: 8 of the most faithful adaptations ever
Adapting canonical literary classics into cinema is an inherently difficult task, as it requires walking a razor's edge between remaining faithful to the text and translating it into another medium.
Medical Xpress / Gut bacteria boost immune system, help send vitamin A to T cells
Scientists at UT Southwestern Medical Center have discovered that gut bacteria help regulate the development of the body's immune system by directing the movement of vitamin A through a previously unrecognized cellular network. ...
Medical Xpress / Health care spending gap between high- and low-income Americans continues to widen, study finds
A new study led by a University of Chicago researcher finds that health care spending in the United States has increasingly diverged between high- and low-income Americans over the past two decades. The analysis shows that ...
Medical Xpress / Research confirms safety in voluntary assisted dying
New research demonstrates that the Victorian model for oral self-administration of voluntary assisted dying (VAD) medication is safe and effective, providing the largest global experience of patient outcomes.
Phys.org / Tiny carbon rings enable a new form of quantum control
Quantum states can be precisely controlled with the help of tiny carbon rings measuring only a few nanometers in size. This is made possible by a class of rarely used electromagnetic dipoles called toroidal moments. Using ...
Tech Xplore / Researchers identify the 'hidden energy cost' of AI agents for the first time
As the era of AI agents—systems that can reason and act autonomously—begins, the power consumption of data centers is emerging as a critical challenge. A KAIST research team has, for the first time, analyzed the computational ...
Medical Xpress / Genetic insights into a fluid-related brain condition in newborns
Early detection and treatment of congenital cerebral ventriculomegaly (CCV)—when a fetus's fluid-filled brain ventricles swell due to a condition called hydrocephalus—can help clinicians prevent developmental or neurological ...
