Medical Xpress / Intermittent hemodialysis not noninferior to continuous renal-replacement therapy
Intermittent hemodialysis as an initial treatment approach is not noninferior to continuous renal-replacement therapy (CRRT) among critically ill patients with acute kidney injury (AKI) with indications for renal replacement ...
Medical Xpress / Common leukemia mutation derails protein positioning during cell division, study reveals
Experts from the University of Nottingham have discovered how a common genetic mutation disrupts the positioning of a key protein during cell division, revealing a new mechanism behind acute myeloid leukemia and a potential ...
Medical Xpress / Skin measurements show link between insomnia and disrupted fear responses
A new computational model using skin conductance measurements to estimate stress-related emotional arousal found a significant difference in learned fear and safety responses over time between adults with and without insomnia.
Medical Xpress / Menopause is marked by a body-wide physiological 'cliff,' study suggests
The final menstrual period is preceded by abrupt "cliff-like" biological changes across multiple body systems, some of which show early signs more than a decade beforehand, according to research published in Nature Medicine. ...
Medical Xpress / The shape of water at a key tau hotspot helps drive dementia-linked clumping
Diseases such as Alzheimer's and frontotemporal dementia are considered neurodegenerative tauopathies, in which tau proteins in the brain misfold and lead to cognitive decline. Until now, it has been unclear how misfolded ...
Phys.org / Baby tooth places macaques in northern Germany more than 300,000 years ago
A research team from the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen and Leiden University in the Netherlands has examined a tooth from the Schöningen archaeological site in ...
Phys.org / Ivy bees fight back against honeybees that drive other pollinators off flowers
Honeybees are outcompeting wild pollinators in the U.K., and new research has found evidence of their aggressive behavior, recording for the first time the extent to which they restrict access to food sources and attack and ...
Tech Xplore / How artificial neural networks build their own learning machinery
As artificial intelligence becomes more powerful, its ability to handle humanlike tasks is undeniable. Artificial neural networks can learn to recognize images, use language or write computer code. Like the brain's circuits, ...
Phys.org / The gooier marine snow is, the better it is at transporting carbon, new study finds
In the deep sea, it never stops snowing. The type of snow that falls in the ocean, known as marine snow, is very different from the flaky geometric wonders that fall on land. Marine snow describes tiny clumps of organic and ...
Phys.org / Local DNA motion inside the cell stays nearly constant throughout interphase
Human genomic DNA is wrapped around core histone proteins to form nucleosomes, the fundamental units of chromatin. During interphase, the period between cell divisions, DNA is replicated and the nucleus becomes larger. At ...
Phys.org / Stabilizing a simple amino acid opens a path to biodegradable sensors
The humble amino acid glycine—the simplest of all amino acids—is everywhere. The human body produces it, and it helps make up our skin, bones and ligaments. It's found in meats like beef and has even been discovered in comets ...
Tech Xplore / Engineers develop wearable solar device to power soldiers' gear in the field
A U.S. soldier may carry up to 20 pounds (9 kilograms) of batteries to power communications equipment and other electronics on missions. New research from FIU could help lighten that load. A team of engineers has developed ...
