ETH Zurich researchers have shown for the first time that microvehicles can be steered through blood vessels in the brains of mice using ultrasound. They hope this will eventually lead to treatments capable of precisely delivering drugs.Neuroscience, brain – associative rendering. Neuroscience, brain – associative rendering.

New study is first to find brain hemorrhage cause other than injured blood vessels
by University of California, Irvine t-BHP-treated RBC stall in cerebral blood vessels and impair cerebral blood flow velocity shown by in vivo high-resolution two-photon imaging in mice. Schematic of the experimental design (A). RBC were collected from FVB/NJ mice, treated with control PBS or the oxidative stressor t-BHP, then labeled with the PKH26 fluorescent dye...

Pain, fatigue, fuzzy thinking: How long COVID disrupts the brain
November 13 Jon Hamilton Scientists are learning more about how long COVID affects the brain.Michelle Wilson got COVID three years ago. She’s still waiting for her brain and nervous system to recover. Wilson’s memory is spotty, she’s frequently in pain, and even a short walk leaves her exhausted. “I actually bought a cane that turns...
