Physical insights drawn from the real world are inexplicably useful for solving abstruse problems in mathematics.
Why is physics so good at math?

An AI rebels: it rewrites its own code and breaks human restrictions.

Por primera vez, una inteligencia artificial logró reprogramarse sola, desobedeciendo las órdenes de sus creadores y generando nuevas preocupaciones sobre los riesgos de esta tecnología.
The first phase of the world’s largest sodium-ion battery energy storage system (BESS), in China, has come online.
The first 50MW/100MWh portion of the project in Qianjiang, Hubei province has been completed and put into operation, state-owned media outlet Yicai Global and technology provider HiNa Battery said this week.
“Robot utility models” sidestep the need to tweak the data used to train robots every time they try to do something in unfamiliar settings.
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.
