C’Dots, silica-encased nanoparticles developed in the lab of engineering professor Ulrich Wiesner, have just begun their first therapeutic human clinical trial. They’re being further developed by Elucida Oncology Inc., a company co-founded by Wiesner.
New study shines light on how plant cells perceive and respond to mechanical forces
Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study in the journal
Science is among the first to directly investigate what one type of these mechanosensitive ion channels is doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how.
Biologists led by Elizabeth Haswell at Washington University in St. Louis discovered that so-called PIEZO channels are not found along the plasma membrane in plant cells as they are in animal cells.

Without requiring vaccines, filled stadiums are unsafe
Some 135,000 fans gathered in the Indianapolis Motor Speedway for the Indy 500 over the 2021 Memorial Day Weekend.
