Researchers uncover how brain circuit elicits hunger responses during starvation

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

Could we eventually see a day where we have cell circuitry nanobot pill that eliminates hunger and obesity as replacement to gastric bypasses? Maybe.

The human body responds to starving conditions, such as famine, to promote the chance of survival. It reduces energy expenditure by stopping heat production and promotes feeding behavior. These “hunger responses” are activated by the feeling of hunger in the stomach and are controlled by neuropeptide Y (NPY) signals released by neurons in the hypothalamus. However, how NPY signaling in the hypothalamus elicits the hunger responses has remained unknown.

Sympathetic motor neurons in the medulla oblongata are responsible for heat production by brown adipose tissue (BAT). Researchers centered at Nagoya University have now tested whether the heat-producing neurons respond to the same hypothalamic NPY signals that control hunger responses. They injected NPY into the hypothalamus of rats and tested the effect on heat production. Under normal conditions, blocking inhibitory GABAergic receptors or stimulating excitatory glutamatergic receptors in the sympathetic motor neurons induced heat production in BAT. After NPY injection, stimulating glutamatergic receptors did not produce heat, but inhibiting GABAergic receptors did. The study was recently reported in Cell Metabolism.

Senolytics – Taking Out The Trash Might Keep You Fit And Healthy

Posted by in categories: biotech/medical, life extension

Clearing out senescent cells could lead to better fitness and health as we age.

From around age forty we start to lose muscle mass due to various aging processes, one of these processes is the accumulation of senescent cells. Senescent cells are simply cells that have become damaged or have reached their maximum number of divisions. Normally these cells are shut down by a kind of self destruct program inside the cell, ready to be disposed of by the immune system.

GWU’s Innovations in Electric Propulsion Technology Help Vector Provide Unprecedented Access to Space

Posted by in categories: materials, satellites

Since our launch in 2016, Vector has focused on connecting space startups and innovators with affordable and reliable space by dramatically increasing access and speed to orbit. And as a result, Vector is reshaping the multi-billion launch market. Building on over 10 years of research to develop the Vector-R launch vehicle, Vector is truly at the forefront of innovation and revolutionizing the next generation of rocket launches. George Washington University has developed ground-breaking plasma steering thrusters which will help put Vector ahead in the great “New Space” race. Our collaboration with George Washington University will help us move closer to achieving our long-term vision of furthering the technological achievements for our industry.

Through this agreement, Vector will license the plasma thruster technology created by the School of Engineering and Applied Science at George Washington University for the Vector-R launch vehicle. The technology will allow us to propel miniature satellites, which are significantly less expensive and made from common materials, and control them while in space. As part of the collaboration, Vector will develop the thruster for commercial space use, and the University will continue to develop the next generation of the technology.

Small spacecraft and satellites are extreme ly difficult to maneuver and control once in space, and George Washington University’s plasma thruster technology helps us manage this problem. The thrusters use titanium as a propellant, which is converted into a gas-like plasma to provide propulsion. The plasma then accelerates and expands into a vacuum at high velocities to produce thrust. This thrust helps the craft overcome drag and maintain the small satellite’s orbit. We plan to use the technology as part of our launch system dedicated to micro spacecraft.
