A Pennington Biomedical Research Center study found that female mice on a high-fat diet given Russian tarragon or bitter melon supplements gained more weight and body fat compared to those not receiving the supplements. However, there was no significant change in insulin sensitivity or body-fat percentages.
A DNA study of over 6,000 dogs found that a specific genetic duplication on chromosome 18 is strongly associated with blue eyes in Siberian Huskies. This discovery sheds light on the genetic underpinnings of eye color in dogs and demonstrates the power of consumer genomic data.
A new study combines imaging and neuropsychological testing to more accurately assess cognitive status, distinguishing individuals with mild cognitive impairment from those with normal cognition. The combined data model achieved an overall accuracy of over 90%, surpassing individual models alone.
A large multi-ethnic study found that high circulating levels of an inflammatory marker are linked to long-term decline in kidney function. The study suggests a novel marker, soluble TNFR-1, is strongly related to kidney function decline over time.
Researchers developed flexible piezoelectric acoustic sensors for improved speaker recognition, achieving sensitivity over two times higher than conventional sensors. These sensors enable 97.5% accurate speaker recognition and diverse voice detection in various environments.
Cell biologist Needhi Bhalla's research reveals a complex chromosomal monitoring system that prevents errors during meiosis, a type of cell division. The system involves checkpoints and molecular mechanisms to ensure proper progression of recombination.
Research at the University of York suggests that Neanderthals had a well-developed system of care for injuries and childbirth challenges. The study of over 30 individuals with minor and serious injuries found evidence of healthcare dating back 1.6 million years ago, indicating a fundamental role in survival strategies.
Scientists discovered a genetic mutation in the CHRNA5 gene that contributes to nicotine dependence and relapse. The study found that this mutation increases nicotine consumption and rates of relapse, offering hope for developing new therapies to combat tobacco addiction.
