The research revealed widespread disruptions in the activity of genes responsible for early embryonic genome activation, metabolic processes, epigenetic regulation, and chromatin structure in embryos from women with PCOS.
It’s a debilitating disease that affects more than 500,000 Australians, but new research from the University of South Australia is offering fresh hope to people living with rheumatoid arthritis (RA).
Low-income patients—and their healthcare providers—are less likely to challenge denials of their health insurance claims than those with household incomes above $50,000, according to University of Massachusetts Amherst research.
The development of renewable polymers for use in healthcare has shown excellent results, especially in biomedicine, such as in controlled drug release. Using materials like cellulose, chitosan, and starch, scientists have developed advanced ways of applying these polymers to the human body. However, turning these discoveries into commercially available products is still a significant challenge.
Researchers have unveiled the transformative potential of micropattern arrays—engineered microstructures—to probe and guide cellular biomechanics. These arrays not only help decipher how cells sense physical cues but also steer tissue regeneration and stem cell fate, paving the way for breakthroughs in tissue regeneration, organ-on-a-chip systems, and disease modeling.
Researchers looked at how sleep habits and sleep fluctuations are related to next-day physical activity. On average, those who went to bed earlier were more physically active the next day. Next-day exercise was highest following earlier than usual bedtimes combined with a person’s normal number of hours of sleep.
