Angiosarcomas of the scalp are aggressive invasive tumors that, more often than not, mimic benign painless skin lesions. We here report a case of angiosarcoma that was timely diagnosed and treated thanks to the dermoscopic rainbow pattern.

Batesian mimics gain protection from predation through the evolution of physical similarities to a model species that possesses anti-predator defences. This protection should not be effective in the absence of the model since the predator does not identify the mimic as potentially dangerous and both the model and the mimic are highly conspicuous. Thus, Batesian mimics should probably encounter ...

Experiments show that a collection of bouncing fluid droplets can behave like microscopic system spins — the intrinsic angular momenta particles. This discovery could lead to better understanding physics spin systems. Complex interactions synchronize droplet motion.

The role of microRNAs (miRs) is shown as a biomarker whose expression level changes have been associated with cancer development and progression. Circulating miRNAs have been postulated as biomarkers for breast cancer. Detection and diagnosis of miRNA markers could provide an improved and sensitive method in the clinical application. In this study, we applied and improved the effective approach...
