Could polyethylene waste could be a thing of the past?
Young and old blood stem cells. Rejuvenating the stem cells that create all blood cells could potentially slow aging. Images from Emmanuelle Passegué.
Could aging actually be slowed by revitalizing old blood?

A major advance in treating obesity
This could work: Restoring memory in people with damaged brains using a memory prosthesis
Is this the way to build a cure for heart attacks?
Top: the two-step oxidation of the bis(triarylamines) molecular series. Bottom: the geometry of the highest conducting trimer (n=3) molecule in the molecular junction. Red and blue regions are artistic depictions on the coupling between the two edge states. CREDIT Liang Li/Columbia University
Molecular electronics start to connect with the invention of a highly conductive molecular nanowire
Tissues cultured in the multi-organ chip (from left to right: skin, heart, bone, liver, and endothelial barrier) maintained their tissue-specific structure and function after being linked by vascular flow. Photo credit: Kacey Ronaldson-Bouchard/Columbia Engineering
Customized to the patient: Novel plug-and-play organ on a chip
MIT researchers have developed an ultrathin loudspeaker that can turn any rigid surface into a high-quality, active audio source. The straightforward fabrication process they introduced can enable the thin-film devices to be produced at scale. Image: Felice Frankel
A paper-thin loudspeaker that can turn any surface into an active audio source
Schematic illustrations of cargo transport by a swarm of molecular robots (top) and fluorescence images of a molecular robot transporting blue sphere-like cargo (bottom). The scale bar is 20 micrometers. By specifying the position of the light irradiation, it is possible to accumulate the cargo at the designated destination (right). The scale bar is 50 micrometers (Mousumi Akter, et al. Science Robotics. April 20, 2022).
Swarming molecular robots increase drug delivery capabilities by 5 times over single robots
Figure 1: Ionic communication: Cross-sectional schematic illustration of an ionic communication device consisting of an implanted transmitter (TX) electrode pair inside biological tissue and a receiver electrode pair (RX) on the surface of the tissue (top left). Frequency responses of ionic communication highlighting is capacity to operate at megahertz frequencies (top right). A 10-link ionic communication transmitter (TX) and receiver (RX) array conforming to the surface of an orchid petal (bottom). Credit: Dion Khodagholy/Columbia Engineering
Using the body’s naturally occurring ions to help transmit data from implantable devices
MediSCAPE imaging of fresh human kidney compared to gold standard periodic acid-Schiff (PAS) histology of the same tissue. Center shows large area scanned using MediSCAPE. Panels point to specific features of the kidney that are either normal or represent disease. 488 nm excited autofluorescence is color-coded in a yellow-blue scale.
