The value of returning a sample of the Martian atmosphere.

The elemental and isotopic abundances of major species in the Martian atmosphere have been determined, but analyses often lack sufficient precision, and those of minor and trace species are frequently not well known. Many important questions about the evolution and current state of Mars require the kind of knowledge that can be gained from analysis of a returned sample of the Martian atmosphere. Key target species include the noble gases, nitrogen, and various species containing carbon, hydrogen, and oxygen, such as methane.

Knowledge, Attitudes, and Decision-Making About Reproductive Health and Epilepsy: A Survey of Health Care Providers and Women With Epilepsy.

Background And Objectives: Cisgender women with epilepsy (WWE) have distinct reproductive health needs. It is unknown to what extent WWE and their health care providers (HCPs) are aware of recent research advances regarding the reproductive health of WWE. This study aimed to survey US health care providers and WWE about their knowledge, attitudes, and decision-making pertaining to reproductive health; their awareness of key findings from recent relevant research; and whether learning of these findings would change their decision-making.

Comparative analysis of sleep physiology using qualitative and quantitative criteria for insomnia symptoms.

Despite decades of research, defining insomnia remains challenging due to its complex and variable nature. Various diagnostic systems emphasize the chronic nature of insomnia and its impact on daily functioning, relying heavily on patient self-reporting due to limitations in objective measures like polysomnography (PSG). Discrepancies between subjective experiences and objective PSG results highlight the need for more nuanced approaches, such as electroencephalogram (EEG) spectral analysis, which reveals distinct patterns of high-frequency activity in individuals with insomnia.
