Cardiac fibroblasts can be directly reprogrammed to form beating heart muscle cells on soft surfaces that match the elasticity of native myocardium. This approach shows increased functional maturation and spontaneously beating iCMs, with implications for treating heart failure and myocardial infarction.
The COVID-19 outbreak has caused immense problems at a macro socioeconomic level and has taken a toll on the physical and mental well-being of individuals worldwide. Caregivers, physicians, and others directly dealing with patients are likely experiencing trauma consequences and burnout syndrome.
A new study suggests that young women who experience a heart attack may have more favorable long-term outcomes compared to men. The research found that second heart attacks were less frequent in women and they were more likely to have healthy arteries. However, women were also at higher risk of stroke compared to men.
Scientists have developed a low-temperature resisting hybrid electrolyte for aqueous zinc-based batteries (ZBBs), exhibiting high zinc-ion conductivity at low temperature. The new electrolyte improved the performance of ZBBs, enabling high energy densities, power densities and long-cycle life at -20°C.
Researchers have developed a new method for creating multicolor single-mode microlasers capable of emitting over the full visible spectrum. The lasers are achieved through heterogeneously coupled cavities constructed with three spherical microcavities and distinct gain media.
A RUDN University linguist found a potential correlation between the number of COVID-19 cases in a country and the presence of aspirated consonants in its main language. The study, published in Medical Hypotheses journal, suggests that languages like English with more aspirated consonants may lead to faster spread of the virus.
A new scoring system is proposed to diagnose COVID-19, taking into account epidemiological evidence, clinical symptoms, and investigations. This simple system can be calculated in minutes and helps classify suspected patients for further evaluation or isolation.
