Recent research has revealed oxytocin’s critical role in enhancing long-term object recognition memory in animals, opening new avenues for Alzheimer’s disease treatment and understanding the cognitive benefits of oxytocin. Credit: SciTechDaily.comA study has demonstrated how activating oxytocin neurons in the brain can significantly improve long-term memory, suggesting a promising approach to combat dementia and Alzheimer’s disease.Oxytocin (OXT) is a hormone that is known for its effects on psychological well-being and…

Recent research has unveiled a connection between anxiety disorders and the TACR3 receptor, highlighting the role of testosterone in mitigating anxiety symptoms. This breakthrough offers new therapeutic possibilities for those suffering from anxiety related to testosterone deficiency. Credit: SciTechDaily.comA groundbreaking study has unveiled a significant link between anxiety disorders and a brain receptor known as TACR3, as well as testosterone.Prof. Shira Knafo, head of the Molecular Cognitive Lab at Ben-Gurion…

Candida albicans usually co-exists peacefully in the body, but under the right conditions it transforms into hyphae, the dark red filaments pictured above, which can form harmful biofilms. Research shows that a gut hormone called peptide YY also plays a vital role in maintaining the health of the gut microbiome by preventing helpful fungi from turning into more dangerous, disease-causing forms.Peptide YY (PYY), a hormone produced by gut endocrine cells that was already known to control appetite, also plays an important…

Recent research has identified a potential trigger for growth cessation in fruit flies, with implications for understanding human development. The study, focusing on the role of the steroid hormone ecdysone, suggests that growth stops not due to body size but due to a self-regulatory switch in the gland producing the hormone.All animals start out as a single-celled organism and then start growing. At some point, of course, they need to stop getting bigger, but the process by which this happens is poorly understood. New…

Almost 25 years since scientists first identified the difference in anesthetic sensitivity between males and females, new research suggests that sex hormones make men more responsive to this state of unconsciousness – and women far less so.Earlier studies have shown that women take longer to be 'put under', to emerge from anesthetic faster than men, and are more likely to experience rare occurrences of awareness while on the operating table. But why this is has been largely theory-based and understudied, which should not…

Canadian researchers have found that women using Combined Oral Contraceptives (COCs) show changes in brain regions related to emotion regulation, raising concerns about the potential impact on brain development and emotional health. These effects may be reversible, highlighting the need for increased awareness and further research in this area.Scientists have discovered that the use of oral contraceptives may influence the morphology of brain regions related to fear. This finding could enhance our comprehension of…

Researchers have identified the specific neurons responsible for controlling how growth hormone affects anxiety and the creation of fear memories, a hallmark of post-traumatic stress disorder. The discovery could lead to a new class of anti-anxiety drugs.Depression, anxiety, and post-traumatic stress disorder (PTSD) affect millions of people worldwide. While the exact mechanisms underlying these conditions are not fully understood, growing evidence suggests that hormones may affect a person’s susceptibility to them.A new…

How can you tell if a dinosaur is female or male? It’s one of the most basic aspects of biology and yet, for the most part, it continues to be a mystery in paleontology. We don’t yet know the sex of most extinct species, even if those in museum displays have gender-specific names like Sue the T.rex or Cliff the Triceratops. But this past October at the annual meeting of the Society of Vertebrate Paleontologists, one scientist offered insight into the work he and his team are doing to uncover hormones in fossil bones.…

Scientists have discovered that a hunger hormone in the gut directly influences the brain’s hippocampus, affecting decision-making related to food. The study, conducted on mice, showed that hunger hormones modify brain activity to either inhibit or permit eating based on the animal’s hunger level. Researchers have found that hunger hormones in the gut directly affect the brain’s hippocampus, influencing eating decisions. This discovery, made through a study on mice, shows how the brain regulates eating based on hunger…
