Correcting the “self-correcting” mythos of science

In standard characterizations, science is self-correcting. Scientists examine each other’s work skeptically, try to replicate important discoveries, and thereby expose latent errors. Thus, while science is tentative, it also seems to have a system for correcting whatever mistakes arise. It powerfully explains and justifies the authority of science. Self-correction thus often serves emblematical...

Correcting Contradictions

This paper describes a manual investigation of the contradiction asymmetries of the SICK corpus, which is the intended testing set for a new system for natural language inference. Any system providing conceptual semantics for sentences, so that entailment-contradiction-neutrality relations between sentences can be identified, needs a baseline test set. The investigation of this test set, a part...

Codes Correcting Two Deletions

In this work, we investigate the problem of constructing codes capable of correcting two deletions. In particular, we construct a code that requires redundancy approximately 8 log2 n+O(log2 log2 n) bits of redundancy, where n denotes the length of the code. To the best of the author’s knowledge, this represents the best known construction in that it requires the lowest number of redundant bits ...

Correcting the scientific record.

This month we are publishing a retraction of a paper by Won et al. entitled “Small molecule–based reversible reprogramming of cellular lifespan.” The Letter, which appeared in our July 2006 issue (Nat. Chem. Biol. 2, 369–374, 2006), described the discovery by high-throughput screening of CGK733, a small molecule that was reported to modulate the ‘senescence clock’ in human cells. In the paper, ...
