Sensory neurons detect internal and external cues in organs and send this information to the brain. Lung cancer exploits this pathway to lessen immune responses.

Genetic data from 139,416 human embryos were used to characterize chromosomal abnormalities, called aneuploidies, that underlie many cases of pregnancy loss. This approach revealed a relationship between aneuploidy and the exchange of DNA between chromosomes during female meiosis and egg formation, and identified common maternal genetic variants associated with meiotic errors.

Fundamental particles called quarks can be created in quantum-correlated pairs. These correlations can be passed on to larger particles that form from the quarks.

The state of the North Atlantic Ocean during the last ice age remains debated. A pair of independent geochemical measures shows that a cold, salty and dense deep-ocean current, known as the North Atlantic Deep Water, continued to form and remained relatively warm, instead of being close to freezing as was assumed previously.
