Pillow Talk: Exploring Disclosures After Sexual Activity
Drawing on physiological research, this study explores disclosures after sexual activity, or ‘‘pillow talk.’’ Oxytocin, better known as the ‘‘bonding hormone,’’ has been associated with physical affection and intimacy. While the hormone was originally studied for its role in childbirth, recent work has started to explore oxytocin’s other effects, such as decreasing stress, decreasing perception...
متن کاملReproductive cross-talk: seed development in flowering plants.
Flowering plants have evolved to be a predominant life form on earth. A common principle of flowering plants and probably one of the main reasons for their evolutionary success is the rapid development of an embryo next to a supporting tissue called the endosperm. The embryo and the endosperm are protected by surrounding maternal tissues, the integuments, and the trinity of integuments, embryo ...

متن کاملReproductive Biology: Receptor-Like Kinases Orchestrate Love Songs in Plants
Genetic studies have identified a family of receptor-like kinases (RLKs) involved in the control of reproduction in the model plant Arabidopsis. Each RLK-dependent signaling pathway is active in cells associated with either male or female gametes. Collectively, these RLKs control the delivery of sperm cells to female gametes.

1512 normal enzyme. Then, they replaced the oxygen in question with a sulfur atom. The reaction didn’t work as well because, by the rules of chemistry, sulfur doesn’t like to bind to magnesium. But sulfur does like manganese and cadmium ions. So they replaced the magnesium with one of these other metal ions and measured the reaction. The researchers saw that these other metal ions restored (or ...
