The most recent signals from science and engineering
Hamming, 1950: how three check bits can repair one error
A damaged bit need not destroy a message. Hamming’s construction adds three carefully chosen checks to four data bits, allowing the receiver to locate and repair any single flipped bit. Its limits are just as important: the seven-bit code cannot reliably distinguish one error from two.
Shannon, 1948: measuring information to communicate reliably
How can a message arrive intact when its signal is disturbed? In 1948, Claude Shannon gave engineers a mathematical framework for separating a message from its physical carrier, measuring how much it can be compressed, and finding the rate below which noise can be overcome with coding. His results established limits and possibilities, not a ready-made universal transmitter.
Camizestrant turns an emerging ESR1 mutation into a treatment-switch signal before radiographic progression
The FDA has granted accelerated approval to camizestrant plus a CDK4/6 inhibitor when an ESR1 resistance mutation emerges in blood ctDNA during first-line therapy, before imaging shows progression. SERENA-6 reported median PFS of 16.0 versus 9.2 months; overall survival remains immature.

Structured, verified knowledge behind the signals
What is a set?
A set groups well-defined objects; membership, inclusion and operations describe its structure.
Graphs, degrees, and Eulerian trails
In a multigraph whose vertices of nonzero degree are all connected, degree parity determines whether every edge can be traversed exactly once.
The law of diminishing returns
With technology unchanged, increasing one input while the others remain fixed often ultimately reduces its marginal product; if it is the only variable input, paid at a constant price, and as long as its marginal product remains positive, this decline raises marginal cost.
Comparative advantage
In the two-good, constant-cost model, reallocation follows opportunity cost; if preferences are strictly increasing in chairs over the bundles compared, a price strictly between the two costs enables mutual gain.
