In our universe: Most distant galaxies observed in 2022: “Webb was made to observe the most distant galaxies in the universe, and in mid-December, scientists confirmed that they had done just that. The telescope has officially observed the four most distant galaxies known, which also means they are the oldest. Webb observed the galaxies as they appeared about 13.4 billion years ago, when the universe was only 350 million years old, about 2% of its current age.” – Rebecca Sohn, Space.com, December 29, 2022 Meanwhile, a much bigger telescope array, the multinational SKAO project, is under construction: Composed of respectively hundreds of dishes and thousands of antennas, the SKAO’s telescopes will be the two most advanced radio telescopes on Earth.

Our universe: A recent buzz is the magnificent new map of the universe from Johns Hopkins University, giving some sense of our universe’s nearly unfathomable size. Astronomer Hugh Ross points out at Reasons to Believe that the universe also seems to be designed for observability: Sound implausible? Well, here’s what he says: “ … there’s a relatively narrow time window in the history of the universe during which astronomers can observe 100% of the universe’s past history. Humans are inside that time window now. I also demonstrated that we are living in the one location within this vast universe where intelligent physical life is possible, and where that intelligent life can observe 100% of the past history of the universe.

Confirmed: “Secret” Tunnels Connect Our Skulls and Brains

The newly confirmed skull tunnels produce immune system cells and funnel them to the brain in case of inflammation or damage

Neuroscientists usesd to think that immune system cells were carried in the bloodstream from, say, big leg bones in order to address brain inflammation following a stroke, injury, or disorder. It turns out that the brain gets neutrophils from much closer to home, right under the scalp. That’s what one group discovered when looking for the cells in the tibia (the larger of the shinbones in the leg) in mice: They found that the skull contributed significantly more neutrophils to the brain in the event of stroke and meningitis than the tibia. But that raised a new question – how were the neutrophils being delivered? “We started examining the skull very carefully, looking at it from all angles, trying to Read More ›
