Battlefield Space: To The Moon And Beyond
Posted by Dan Breeden in categories: military, satellites
After a successful test flight of NASA’s Artemis-1 moon mission, the space agency now turns its attention to returning Americans to the moon within two to three years. But the U.S. is not the only country with lunar ambitions. China is aggressively pursuing it own plans to land astronauts on the moon and build out a permanent base. Both countries openly talk about the need to have a military presence in space to defend against the other. Already, a dangerous cold war cat-and-mouse game involving U.S., Russian and Chinese satellites plays out every day. NBC News goes in-depth to explore the challenges in a potential battlefield that is complex, congested and contested.

Hubble Telescope Accidentally Discovers a MIND-BLOWING New Galaxy
Posted by Dan Breeden in category: cosmology
Humankind is getting very good at looking deep into space: We have already seen two neutron stars colliding, we have encountered mysterious radio blasts and we are about to see, for the first time, the event horizon of a black hole.
But there are still some surprises out there, right here in our own corner of the Universe.

Probiotic Alleviates Muscle Aging in New Study
Posted by Paul Battista in categories: biotech/medical, life extension
Bened Biomedical scientists increase muscle strength and size and stimulate the ghrelin hormone with Lactobacillus parcasei PS23, a probiotic, in age-accelerated mice.
While I would say your timeline is generally too long, I think the steps are pretty good. This was a visceral read for me.

Saccade vigor reflects the rise of decision variables during deliberation
Posted by Saúl Morales Rodriguéz in category: neuroscience
During deliberation, as we quietly consider our options, the neural activities representing the decision variables that reflect the goodness of each option rise in various regions of the cerebral cortex.1,2,3,4,5,6,7 If the options are depicted visually, we make saccades, focusing gaze on each option. Do the kinematics of these saccades reflect the state of the decision variables? To test this idea, we engaged human participants in a decision-making task in which they considered two effortful options that required walking across various distances and inclines. As they deliberated, they made saccades between the symbolic representations of their options. These deliberation period saccades had no bearing on the effort they would later expend, yet saccade velocities increased gradually and differentially: the rate of rise was faster for saccades toward the option that they later indicated as their choice. Indeed, the rate of rise encoded the difference in the subjective value of the two options. Importantly, the participants did not reveal their choice at the conclusion of deliberation, but rather waited during a delay period, and finally expressed their choice by making another saccade. Remarkably, vigor for this saccade dropped to baseline and no longer encoded subjective value. Thus, saccade vigor appeared to provide a real-time window to the otherwise hidden process of option evaluation during deliberation.
