Reversing Cognitive Decline

Posted by in categories: life extension, neuroscience

A team of Stanford researchers led by Professor Wyss-Coray set out to find out which genes were linked to age-related cognitive decline. Not only did the researchers find the culprit, they were able to reverse cognitive decline and rejuvenate aged mouse brains.

Searching for the cause of cognitive decline

Microglia are immune cells that reside in the brain and spinal cord. These cells mediate immune responses in the central nervous system and act like other macrophages, clearing cellular debris and dead neurons from nervous tissue through the process of phagocytosis (cell eating).

Blue Origin urging Air Force to postpone launch competition

Posted by in categories: military, satellites

COLORADO SPRINGS — Blue Origin wants the U.S. Air Force to wait until 2021 before picking the two companies it intends use for launching critical military satellites in the decade ahead.

The Air Force, however, aims to solicit proposals this spring and choose its two preferred launch providers in 2020 — perhaps a year or more before the new rockets that the Air Force is fostering at Blue Origin, United Launch Alliance and Northrop Grumman make their first flights.

All three companies were chosen in October by the Air Force Space and Missile Systems Center to share $2.3 billion in so-called Launch Service Agreement (LSA) funding to support development of next-generation rockets capable of meeting the military’s satellite launch needs.

Made In Space unveils small satellite interferometry tool

Posted by in category: satellites

COLORADO SPRINGS – Made in Space unveiled a product April 8 to help customers conduct interferometry missions on small satellites.

Possible applications for the new product, Optimast-Structurally Connected Interferometer (Optimast-SCI) include space situational awareness and detection of near-Earth objects, Andrew Rush, Made In Space president and chief executive, told SpaceNews.

Traditional space-based interferometry missions bring along large deployable structures to separate their telescopes or other instruments. Hinges and mechanical systems on the deployable structures allow them to be folded in launch fairings and extended in orbit.
