Paraconsistent logic challenges this standard view. A logical consequence relation is said to be paraconsistent if it is not explosive. Thus, if a consequence relation is paraconsistent, then even in circumstances where the available information is inconsistent, the consequence relation does not explode into triviality. Thus, paraconsistent logic accommodates inconsistency in a controlled way that treats inconsistent information as potentially informative.
The prefix ‘para’ in English has two meanings: ‘quasi’ (or ‘similar to, modelled on’) or ‘beyond’. When the term ‘paraconsistent’ was coined by Miró Quesada at the Third Latin America Conference on Mathematical Logic in 1976, he seems to have had the first meaning in mind. Many paraconsistent logicians, however, have taken it to mean the second, which provided different reasons for the development of paraconsistent logic as we will see below.
Paraconsistent logic is defined negatively: any logic is paraconsistent as long as it is not explosive. This means there is no single set of open problems or programs in paraconsistent logic. As such, this entry is not a complete survey of paraconsistent logic. The aim is to describe some philosophically salient features of a diverse field.
“It’s an interesting question to ask: Are there things other than a black hole” that “will give you a hint about what new physics could look like?” added Bah. “But before you get there, you need to know how to tell whether you have a black hole or not, and to do that you have some prototype examples of things that are not black holes to be able to compare.”
Black holes are among the most fascinating and puzzling objects ever observed in our universe. These massive compact entities have so much gravitational power that nothing, not even light, can escape beyond their borders, known as the event horizon. Scientists have imaged black holes with the Event Horizon Telescope and have captured the ripples that these objects make in spacetime, which are called gravitational waves.

Researchers discover Chimno, the gene responsible for the juvenile stage in insects. This gene is present in mammals and could play a key role in cancerous processes.
The study, which was published in the journal eLife and led by the Institute for Evolutionary Biology (IBE, CSIC-UPF) and the IRB Barcelona, has revealed that the Chinmo gene is responsible for establishing the juvenile stage in insects. It also confirms that the Br-C and E93 genes play a regulatory role in insect maturity. These genes, which are also present in humans, act as a promoter and as a suppressor, respectively, of cancerous processes.
The results of the research, which was carried out with the fruit fly Drosophila melanogaster and the cockroach Blatella germanica, reveal that these genes have been conserved throughout the evolution of insects. Therefore, it is believed that they could play a key role in the evolution of metamorphosis.

A long, long time ago, back in the early exciting days of raltegravir, the first HIV integrase inhibitor, we learned something important from a clinical trial with disappointing results. The trial bore the (barely) hidden name of the company that developed the drug — SWITCHMRK, get it? — and had a profound impact on how we managed virologically suppressed patients for years.
What did we learn? Namely, that it was risky to switch stable people from their “high resistance barrier” regimen of lopinavir/ritonavir plus NRTIs to raltegravir plus NRTIs if they harbored viruses with NRTI resistance. Some of the participants who had a history of treatment failure who switched ended up experiencing virologic rebound with integrase inhibitor resistance, which made the switch to raltegravir not noninferior (sorry for the double negative) to continuing lopinavir/ritonavir.
The interpretation was that despite the potency and excellent tolerability of raltegravir — massively better than lopinavir/ritonavir — it wasn’t enough to maintain viral suppression reliably unless the NRTIs were also fully active. Based on these results, for years we steered clear of use of this valuable drug class in any setting where we couldn’t use at least one other fully active drug.
