The future of humanity and the environment are intertwined. Our collective growth shapes disrupts environmental systems at planetary-scale. We pursue increasingly technological futures, while warning need to repair natural biosphere that sustain us. Facing globally interconnected challenges, scientific approaches guide our decision-making have never been more important for informing future. Physicalist (physical-only), reductionistic worldviews, which strive eliminate subjectivity, provide conceptual framing mainstream views purport completely frame describe biological life. However, we observe ample case studies from biology, ecology, human health, animal behavior, other life sciences where course events shaped by intrinsic cognitive subjective assessments benefits drawbacks. It is argued such perceptions, adaptive goal-directed behaviors, represent an overlooked non-material facet or dimension, linked bioelectric read/write/compute capacity, critical organism-, ecosystem-, biosphere-scales.

In birds and insects, the female uptakes sperm for a specific duration post-copulation known as ejaculate holding period (EHP) before expelling unused mating plug through ejection. this study, we found that Drosophila melanogaster females shortens EHP when incubated with males or mated shortly after first mating. This phenomenon, which termed m ale- i nduced E HP s hortening (MIES), requires Or47b+ olfactory ppk23+ gustatory neurons, activated by 2-methyltetracosane 7-tricosene, respectively. These odorants raise cAMP levels in pC1 responsible processing male courtship cues regulating receptivity. Elevated neurons reduce reinstate their responsiveness to cues, promoting re-mating faster study established MIES genetically tractable model of sexual plasticity conserved neural mechanism.

Aggression and mating of male mice are strongly associated with Esr1-expressing neurons in the bed nucleus stria terminalis (BNSTpr) hypothalamus vomeronasal pathway. By projecting to downstream hypothalamus, upstream BNSTpr Esr1 gates aggression maternal behavior female mice. The medial preoptic area (MPOA) ventrolateral subdivision ventromedial (VMHvl) two subdivisions downstream. In addition receiving projections from BNSTpr, there is also a mutual projection between MPOA VMHvl. process transforming sex information into aggression, MPOA, VMHvl act as messengers information, finally producing inhibitory or excitatory projection. These different direction, but they all work together control selection that most conducive defense reproduction when encounter Here, we summarized property function connections these encode highlight importance benefits cells aggression.
