Messenger RNA can travel between different types of stem cells through tunnel-like structures, as revealed by a new study. By studying interactions between mouse and human stem cells, they discovered that this RNA transfer can reprogram human cells to an earlier developmental state. This groundbreaking finding not only sheds light on an underexplored form of cellular communication but also suggests promising applications in regenerative medicine without using artificial genetic modifications or external chemicals.
A researcher at Osaka Metropolitan University examined the impact of opening a multifunctional facility on residents' daily walking time. The results indicate that the facility significantly increased the average walking time of visitors compared to non-visitors.
Monogamous and non-monogamous individuals report similar levels of satisfaction in both their relationships and sex lives, according to a comprehensive new meta-analysis.

Key findings
• This study observed a decreasing global burden of silicosis. However, the trends differed across countries and regions. In addition, the silicosis age-standardized incidence rate (ASIR) and age-standardized disability-adjusted life years (DALYs) rate (ASDR) were higher in males.
What is known and what is new?
• Previous studies have reported various health metrics of silicosis in different countries and regions worldwide.
• This cross-sectional study provides the most up-to-date estimates of the incidence, number of deaths, and DALYs resulting from silicosis and their temporal trends based on data from 204 countries and regions, with significant differences by sex, region, country, age, and sociodemographic index. In addition, the global ASIR, age-standardized mortality rate, and ASDR of silicosis were projected for the next 30 years.
What is the implication, and what should change now?
• Silicosis continues to pose a public health issue, and it is essential to enhance health interventions in certain regions to reduce the damage inflicted by this condition.
As little as five minutes a day of eccentric exercise could offer significant health benefits to those living a stagnant lifestyle, researchers from Edith Cowan University (ECU) found.
