In a study of vaginal births in New York State hospitals, labor neuraxial analgesia -- having an epidural or combined spinal and epidural -- was associated with a decreased risk of severe maternal morbidity. Deliveries with a neuraxial analgesic also lessened the risk of post-partum hemorrhaging, the leading cause of preventable severe maternal morbidity. The researchers found that a decreased risk of severe maternal morbidity associated with neuraxial analgesia was similar between non-Hispanic White women and racial and ethnic minority women.

Researchers report on the development of a low-cost, portable, non-invasive device that uses light and saliva to test COVID-19 patients in less than 30 minutes. The results have shown that the device can detect very low concentrations of SARS-CoV-2 with a sensitivity of 91.2 percent and a specificity of 90 percent, similar to that of PCR but as fast as an antigen test.

Researchers have applied the tools of neuroscience to study when and how an artificial neural network can overcome bias in a dataset. They found that data diversity, not dataset size, is key and that the emergence of certain types of neurons during training plays a major role in how well a neural network is able to overcome dataset bias.

Mental speed -- the speed at which we can deal with issues requiring rapid decision-making -- does not change substantially over decades. Psychologists have come to this conclusion. They evaluated data from a large-scale online experiment with over a million participants. The findings of the new study suggest that the speed of cognitive information processing remains largely stable between the ages of 20 and 60, and only deteriorates at higher ages.
