This episode #20 of my “Pessimistic guide to Anti-Aging Research” titled “Healthspan First, Lifespan –Distant Second”.

When we are dreaming of physical immortality, we really mean not one but two very different immortalities: the one for our body, and quite another for our spirit. The body permits essentially any kind of interventions, modifications, replacements or even transformations for the sake of staying healthy and young indefinitely. In contrast, the spirit absolutely demands the preservation of our unique personalities and memories and, therefore, does not make allowances for treatments that violate this condition.

The Earth, solar system, the entire Milky Way and the few thousand galaxies closest to us move in a vast “bubble” that is 250 million light years in diameter, where the average density of matter is half as high as for the rest of the universe. This is the hypothesis advanced by a theoretical physicist from the University of Geneva (UNIGE) to solve a conundrum that has been splitting the scientific community for a decade: At what speed is the universe expanding? Until now, at least two independent calculation methods have arrived at two values that are different by about 10% with a deviation that is statistically irreconcilable. This new approach, which is set out in the journal Physics Letters B, erases this divergence without making use of any “new physics.”

The has been expanding since the Big Bang occurred 13.8 billion years ago—a proposition first made by the Belgian canon and physicist Georges Lemaître (1894−1966), and first demonstrated by Edwin Hubble (1889−1953). The American astronomer discovered in 1929 that every galaxy is pulling away from us, and that the most distant galaxies are moving the most quickly. This suggests that there was a time in the past when all the galaxies were located at the same spot, a time that can only correspond to the Big Bang. This research gave rise to the Hubble-Lemaître law, including the Hubble constant (H0), which denotes the universe’s rate of expansion. The best H0 estimates currently lie around 70 (km/s)/Mpc (meaning that the universe is expanding 70 kilometers a second more quickly every 3.26 million light years). The problem is that there are two conflicting methods of calculation.

This month, an international team put all of those ingredients together, turning theory into reality.

The three labs, scattered across Padova, Italy, Zurich, Switzerland, and Southampton, England, collaborated to create a fully self-controlled, hybrid artificial-biological neural network that communicated using biological principles, but over the internet.

The three-neuron network, linked through artificial synapses that emulate the real thing, was able to reproduce a classic neuroscience experiment that’s considered the basis of learning and memory in the brain. In other words, artificial neuron and synapse “chips” have progressed to the point where they can actually use a biological neuron intermediary to form a circuit that, at least partially, behaves like the real thing.

NASA’s Ames Research Center in California has issued a mandatory policy for employees to work from home after one worker tested positive for the coronavirus responsible for COVID-19.

The research center, which is located in Moffett Field in the Silicon Valley, has been placed on restricted access after the employee was confirmed to have the coronavirus on Sunday (March 8).
