A collection of sixteen senior scientists have created an academy in Boston in order to showcase the important work currently being conducted on human aging and how researchers are developing ways to slow or even reverse it.
The Academy for Health and Lifespan Research is a nonprofit organization that will be organizing a series of forums at which researchers will share knowledge and research data, helping to improve the flow of information in this field.
The Academy will also be actively lobbying governments around the world to improve funding for aging research and to help improve regulatory pathways in ways that make it easier to develop therapies that target the aging processes in order to prevent age-related diseases.

“Dongsheng’s fabulous work on the involvement of the hypothalamus in aging first came to my attention six years ago, as a result of a groundbreaking paper on the role of GnRH, and he spoke at the last Cambridge conference in 2013. His group’s research has since continued to make immense progress, including very recent advances, and I’m delighted that he has agreed to update us in Berlin”, says Aubrey de Grey.

Having a muted RSA and an elevated resting heart rate reflects a heightened state of arousal, which is an appropriate response to danger, says Amy Vaughan Van Hecke, associate professor of psychology at Marquette University in Milwaukee, Wisconsin, who was not involved in the study.
The part of the nervous system that regulates heart rate and breathing is involved in autism, a new study suggests.
Specifically, the changes in heart rate that ordinarily accompany breathing are slow to develop in autistic children.
Heart rate usually speeds up slightly as a person inhales and slows as she exhales. These fluctuations, known as respiratory sinus arrhythmia (RSA), serve as a proxy for the activity of the autonomic nervous system, which regulates heart rate and breathing, among other functions. The fluctuations are also important for regulating emotions and attending to social cues.
Five-thousand tons of water-ice delivered to cislunar space per two-year mission! In a recent announcement, TransAstra Corporation proposed a spacecraft able to achieve this. They call it the Queen Bee, a new part of the Asteroid Provided In-Situ Supplies (APIS; Apis) architecture. Queen Bee is a large scale version of their asteroid mining spacecraft design.
TransAstra is a Los Angeles, California based aerospace company founded in 2015 by Joel Sercel. Their goal is to help make industrial processes in space possible. A key process they study is extracting volatiles, including water, from small Near Earth Asteroids (NEA). Their past work has focused on Optical Mining, asteroid encapsulation, and solar thermal thrusters for the mining and utilization of carbonaceous Near Earth Asteroid (NEA) volatiles.
