Published in the journal Scientific Reports, researchers have created realistic, skin-like replicas made of Ecoflex, a type of silicone rubber that can potentially serve as a platform to evaluate risks of bacterial infections from intravenous catheters and test wearable sensors, among other biomedical applications. The study found that EcoFlex-based skin replicas can be engineered to mimic actual skin textures, wettability, and elasticity, simulating the conditions where bacteria grow and adhere.

Medical artificial intelligence (AI) has progressed rapidly over the years, driven by novel foundation and large language models. This is highly promising for transforming medical education and healthcare delivery. Now, a review in the Chinese Medical Journal by researchers from China highlights the prospects and points to challenges related to data collection, analysis, and privacy. It emphasizes the importance of effective collaboration among various stakeholders to ensure a bright future for AI in healthcare.

One of the biggest mysteries in science – dark energy – doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is growing equally in all directions. They employed the concept of dark energy as a placeholder to explain unknown physics they couldn't understand, but the contentious theory has always had its problems. Now a team of physicists and astronomers at the University of Canterbury in Christchurch, New Zealand are challenging the status quo, using improved analysis of supernovae light curves to show that the Universe is expanding in a more varied, "lumpier" way.

A recent study led by researchers at the University of Arizona Cancer Center and Northern Arizona University found that Native American women were disproportionately affected by vaginal dysbiosis, a disruption in the balance of bacterial that increases the risk of human papillomavirus infection, which can cause cervical cancer.
