Just two weeks after launching from Vandenberg Space Force Base in California, NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is “To discover and expand knowledge for the benefit of humanity.”

A documentary and journey into the future exploring the possibilities and predictions of artificial intelligence. This timelapse of the future explores what is coming, from robots that are too fast for humans to see, to A.I. bots from Microsoft (bringing back loved ones to life) and Google’s laMDA (replacing the need for online searches).

Elon Musk’s Neuralink goes from a medical and healthcare device, to helping people become superhuman – with intelligence amplification, and add-ons that connect to the brain chip.

Artificial general intelligence begins to design an A.I. more powerful than itself. People begin to question if humanity has reached the technological singularity. Artificial Super Intelligence emerges from the AGI.

And further into the deep future. Human consciousness becomes digitized and uploaded into a metaverse simulation. It is merged with A.I. creating hybrid consciousness – which spreads across the cosmos. Matrioshka brains and Dyson Spheres host humanity’s consciousness in a cosmic simulation network.

It was a big year. Fermilab discovered possible evidence of new physics with the muon G-2 experiment. Physicists created a time crystal, a new phase of matter that appears to violate one of nature’s most cherished laws. And we got a glimpse of an enormous pair of bubbles towering over the Milky Way.

Mitochondria are pivotal for bioenergetics, as well as in cellular response to viral infections. Nevertheless, their role in COVID-19 was largely overlooked. Here, we analyzed available bulk RNA-seq datasets from COVID-19 patients and corresponding healthy controls (three blood datasets, N = 48 healthy, 119 patients; two respiratory tract datasets, N = 157 healthy, 524 patients). We found significantly reduced mtDNA gene expression in blood, but not in respiratory tract samples from patients. Next, analysis of eight single-cells RNA-seq datasets from peripheral blood mononuclear cells, nasopharyngeal samples, and Bronchoalveolar lavage fluid (N = 1,192,243 cells), revealed significantly reduced mtDNA gene expression especially in immune system cells from patients. This is associated with elevated expression of nuclear DNA-encoded OXPHOS subunits, suggesting compromised mitochondrial-nuclear co-regulation. This, together with elevated expression of ROS-response genes and glycolysis enzymes in patients, suggest rewiring toward glycolysis, thus generating beneficial conditions for SARS-CoV-2 replication. Our findings underline the centrality of mitochondrial dysfunction in COVID-19.

Astronomers have produced the most comprehensive image of radio emission from the nearest actively feeding supermassive black hole to Earth.

The emission is powered by a central black hole in the galaxy Centaurus A, about 12 million light years away.

As the black hole feeds on in-falling gas, it ejects material at near light-speed, causing ‘radio bubbles’ to grow over hundreds of millions of years.
