Last month, a team from North Carolina State University and Johns Hopkins University found a workaround. They embedded DNA molecules, encoding multiple images, into a branched gel-like structure resembling a brain cell.

Dubbed “dendricolloids,” the structures stored DNA files far better than those freeze-dried alone. DNA within dendricolloids can be repeatedly dried and rehydrated over roughly 170 times without damaging stored data. According to one estimate, each DNA strand could last over two million years at normal freezer temperatures.

Unlike previous DNA computers, the data can be erased and replaced like memory on classical computers to solve multiple problems—including a simple chess game and sudoku.

The FDA approved amivantamab-vmjw in combination with standard chemotherapy for the treatment of certain adults with non-small cell lung cancer, according to the agent’s manufacturer.

The indication applies to adults with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or L858R substitution mutations whose disease progressed on or following treatment with an EGFR tyrosine kinase inhibitor.

Amivantamab-vmjw (Rybrevant, Janssen) is an EGFR and mesenchymal epithelial transition (MET) factor bispecific antibody that targets activating and resistant EGFR and MET mutations and amplifications.

In Disguised Queries, I talked about a classification task of “bleggs” and “rubes”. The typical blegg is blue, egg-shaped, furred, flexible, opaque, glows in the dark, and contains vanadium. The typical rube is red, cube-shaped, smooth, hard, translucent, unglowing, and contains palladium. For the sake of simplicity, let us forget the characteristics of flexibility/hardness and opaqueness/translucency. This leaves five dimensions in thingspace: Color, shape, texture, luminance, and interior.

Scientists at the Max-Planck-Institute for Intelligent Systems (MPI-IS) have developed hexagon-shaped robotic components, called modules, that can be snapped together LEGO-style into high-speed robots that can be rearranged for different capabilities.

The team of researchers from the Robotic Materials Department at MPI-IS, led by Christoph Keplinger, integrated artificial muscles into hexagonal exoskeletons that are embedded with magnets, allowing for quick mechanical and electrical connections.

The team’s work, “Hexagonal electrohydraulic modules for rapidly reconfigurable high-speed robots” was published in Science Robotics on September 18, 2024.
