New Study Unveils Serotonin’s Key Role in Fertility and Depression

Posted by in categories: biotech/medical, health, neuroscience

Scientists from Nagoya University in Japan have identified the role of serotonin neurons in linking glucose availability to reproductive health. Their research demonstrates how elevated glucose levels stimulate serotonergic neurons, leading to the release of serotonin, which in turn activates kisspeptin neurons responsible for reproductive hormone release. These findings explain why poor nutrition affects fertility and suggest potential treatments for depression-induced infertility through the use of selective serotonin reuptake inhibitors (SSRIs).

Scientists from Nagoya University in Japan have clarified the connection between energy levels and fertility in both animals and humans. They discovered that signaling from serotonin neurons plays a crucial role in maintaining reproductive function by detecting glucose availability, which in turn enhances the release of the reproductive hormone gonadotropin. These findings also offer an explanation for the reduced fertility seen in individuals with depression and suggest potential treatments. The study was published in Scientific Reports.

People who lack sufficient nutrition encounter problems with their reproductive health. For example, ballet dancers can experience menstrual disruptions, and women who fast can struggle to conceive. According to a new study led by Designated Associate Professor Sho Nakamura and Professors Hiroko Tsukamura and Satoshi Ohkura, one of the main factors that affect a person’s reproductive health is glucose availability.

New 3D-printed microscale photonic lantern opens opportunities for spatial mode multiplexing

Posted by in category: energy

Optical waves propagating through air or multi-mode fiber can be patterned or decomposed using orthogonal spatial modes, with far-ranging applications in imaging, communication, and directed energy. Yet the systems that perform these wavefront manipulations are cumbersome and large, restricting their utilization to high-end applications.

New model suggests partner anti-universe could explain accelerated expansion without the need for dark energy

Posted by in categories: cosmology, information science, quantum physics

The accelerated expansion of the present universe, believed to be driven by a mysterious dark energy, is one of the greatest puzzles in our understanding of the cosmos. The standard model of cosmology called Lambda-CDM, explains this expansion as a cosmological constant in Einstein’s field equations. However, the cosmological constant itself lacks a complete theoretical understanding, particularly regarding its very small positive value.

21 New Laser Materials Uncovered in Groundbreaking Global Study

Posted by in categories: robotics/AI, transportation

Utilizing distributed self-driving lab technology, the University of Toronto’s Acceleration Consortium rapidly identified 21 high-performing organic solid-state lasers (OSL) materials, marking a significant advance in molecular optoelectronics and paving the way for future materials discovery.

Organic solid-state lasers (OSLs) offer significant potential for various applications thanks to their flexibility, color adjustability, and high efficiency. Nevertheless, they are challenging to produce. With the need for potentially over 150,000 experiments to identify viable new materials, fully exploring this space could take many lifetimes. In fact, in the previous few decades, only 10–20 new OSL materials have been tested.

Researchers with the Acceleration Consortium based at the University of Toronto, took up this challenge and used self-driving lab (SDL) technology that, once set up, enabled them to synthesize and test over 1,000 potential OSL materials and discover at least 21 top performing OSL gain candidates in a matter of months.
