Medical Xpress / Fecal transplants from older mice found to significantly improve ovarian function and fertility in younger mice
A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all ...
Dialog / The wetland puzzle that stumped hydrology for decades—how physics and AI joined forces to predict unmeasured regions
For years, the Prairie Pothole Region has bothered me in a very specific way. On a map, it looks like a normal landscape: fields, gentle slopes, small streams. But hydrologically, it behaves like something else entirely. ...
Medical Xpress / Pathogen-agnostic testing reveals hidden respiratory threats in negative samples
The COVID-19 pandemic brought the term "Polymerase Chain Reaction testing" into the mainstream. The PCR method is a type of nucleic acid amplification test (NAAT) that detects a pathogen by finding and amplifying components ...
Medical Xpress / Brain activity and breathing rhythms operate separately in deepest sleep, finds research
Could the deepest parts of the brain hold some of the secrets of sleep that still remain elusive to science? A team from Hackensack Meridian Health and its Center for Discovery and Innovation (CDI) has produced a new in-depth ...
Medical Xpress / Tuberculosis cases have been rising as public health agencies struggle to keep up
In Johnson County, Iowa, the number of tuberculosis cases has increased in recent years—and so has the cost of containing it. The cost of contact tracing and surveillance, traveling each day to patients' homes to ensure ...
Medical Xpress / Tiled amplicon sequencing could transform tuberculosis care
When the COVID-19 pandemic was at its peak, and multiple variants were threatening lives around the world, scientists relied on a process called "tiled amplicon sequencing" to track the virus's spread. Now, an international ...
Medical Xpress / X-rays miss it for weeks: How a blood test may spot a common post-surgery condition early
Heterotopic ossification (HO) is a common post-surgery condition where bone abnormally forms within soft tissues. A new study out of Mass General Brigham assesses the viability of a simple blood test to detect HO long before ...
Tech Xplore / Palm-sized piezo robot combines mobility with sub-micrometer positioning accuracy
With the speed at which technology advances, there is little room for suboptimal performance and out-of-date tech. Precise positioning is a field where advancement is needed, as many conventional applications feature tools ...
Phys.org / Arrowhead marks found in Central Asia could prove the existence of Homo sapiens 80,000 years ago
Unretouched triangular microlithic projectile points have been identified from their impact traces in the oldest occupation layers of the Obi-Rakhmat site in Uzbekistan, dating to 80,000 years ago. Their size corresponds ...
Phys.org / A tool lets residents track Texas power outages and aids in disaster response
Texas is known nationwide for its grueling hot summers. However, hurricanes and occasional winter weather can have a harsher impact on citizens and infrastructure due to the effects of power outages. Led by director and primary ...
Medical Xpress / Ultra-processed foods in preschool years associated with behavioral difficulties in childhood
A team led by researchers at the University of Toronto has found an association between ultra-processed foods in early childhood, and behavioral and emotional development. Specifically, the team found that higher ultra-processed ...
Phys.org / Discovery of natural mechanism behind ferroptosis solves longstanding puzzle in cell biology
After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...
