  • Reproducing the sensation of flexibility

    By decoupling cutaneous and kinesthetic signals, EPFL’s SORI (Softness Rendering Interface) device faithfully reproduces the sensation of flexibility of a set of real materials, thus filling a gap in the field of robotics and enabling numerous applications where this perception is essential, from the exploration of the seabed to robot-assisted surgery.

     

     

    Strongly connected neurons thanks to axons

    Bringing together 1,400 terabytes of digital data, the new three-dimensional mapping of a cubic millimeter of human brain includes 57,000 neurons, 230 millimeters of blood vessels and 150 million synapses. Some pairs of neurons are strongly connected to each other by axons — up to 50 connections. Some axons also form a sort of intertwined ball of knots.

     

     

    Restoring sensation and movement with red light

    With a one-minute dose of 660 nm red light delivered daily over a seven-day period, a reduction in tissue scarring from spinal cord injuries was seen. This dose provides significant improvements for patients, particularly in restoring sensation and movement, through the regeneration of damaged nerve cells.

     

     

    Cerebellum controls movements, regulates complex social and emotional behaviors

    The cerebellum contains three-quarters of all neurons in the brain. They are organized in an almost crystalline manner, with a regularity and ordering that contrasts with the tangle of neurons that we observe in the normal brain. In addition to controlling movements, the cerebellum regulates complex social and emotional behaviors. To exert this global influence, it is the data processing center with connections throughout the brain.

    (78aH*) : August 6th is the anniversary of the atomic bomb explosion on Hiroshima in 1945.
    This date represents the entrance of Humanity into the age of Revelation (Apocalypsis).
    Thus, since August 6, 2023, we are in 78 aH, (meanning 78 after Hiroshima).
    It is also an “atheist” and universal calendar to replace the existing “monotheist”, religious and non universal calendars.
