Today I learned about optogenetics. It's a biological technique that involves the use of light to control cells in living tissue, typically neurons, that have been genetically modified to express light-sensitive ion channels. It is a neuromodulation method that uses a combination of techniques from optics and genetics to control and monitor the activities of individual neurons in living tissue—even within freely-moving animals—and to precisely measure these manipulation effects in real-time. https://en.wikipedia.org/wiki/Optogenetics By shining with a laser in a mouse-brain, they can activate neurons and change the behavior. Neuroscientists at Stanford University in California conducted their experiments on mice that were genetically engineered to have light-sensitive neurons in a brain region called the orbitofrontal cortex.https://www.nature.com/news/laser-used-to-control-mouse-s-brain-and-speed-up-milkshake-consumption-1.20995

No. The belief in afterlife is often due to wishful thinking.

Does 'being drunk' has an effect on this?

I sometimes have blurred vision(more then usual) and then I can somehow look for focus to have a 'clear' vision. I do have a neuromuscular disease...

Today I learned about marine heatwaves. Those are periods of extreme warm sea surface temperature that persist for days to months and can extend up to thousands of kilometres. Some of the recently observed marine heatwaves revealed the high vulnerability of marine ecosystems and fisheries to such extreme climate events.http://www.nature.com/articles/s41586-018-0383-9

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of the star that makes life on Earth possible. The mission’s findings will help researchers improve their forecasts of space weather events, which have the potential to damage satellites and harm astronauts on orbit, disrupt radio communications and, at their most severe, overwhelm power grids. https://www.nasa.gov/press-release/nasa-ula-launch-parker-solar-probe-on-historic-journey-to-touch-sun

Today I learned a group of crows is called a murder. It reminds me of 'The Birds' Hitchcock. http://thekidshouldseethis.com/post/why-is-a-group-of-crows-called-a-murder

That's a very normal state of affairs. Science constantly tries to solve the things which are 'not understood'. The scientific knowledge grows all the time. There are atm many 'theories' concerning space and time., future will tell which are correct and which are not. The incorrect ones will disappear out the world of science and the correct ones may form new scientific theories. This is imo the beauty of science. It a self sustaining process…..so science remains scientific. But this thread is about Space.. The Holographic basically states our 3D world (incl space)arises from 2D information. https://en.wikipedia.org/wiki/Holographic_principle https://phys.org/news/2017-01-reveals-substantial-evidence-holographic-universe.html It might look like a wild idea of a crazy scientist but it's not. A quote of Sherlock Holms explains how you should interpret the holographic principle and how it was formed. "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." Hiroshi Ooguri 's quantumgravity model(space time is built by entanglement) leans on the holographic principle. https://www.ipmu.jp/en/node/2174 Leonard Susskind created a model where he shows entanglement hooks space together.https://youtu.be/lH-3bFqtJjg These models fit with the theory that states the Big Bang model implies a high degree of entanglement.(everything is entangled)https://arxiv.org/abs/1205.1584 this concerns Holographic Entanglement Entropy.https://arxiv.org/pdf/1609.01287.pdf What do you think of this? It seems a matter of time before there is scientific evidence for the holographic principle.

What does it matter????????????????????? Gee! 'scientists use 'time' all the time (pun intended) , while at the same time they have no clue what it actually is! And you really think it doesn't matter? Ah well..... Science is full of things we have no clue what it really is. Why do we have to know what time is, to use it?

What does it matter we can't explain what time is? Logic dictates we will be able in the future.

I learned the Kermode bear is a rare subspecies of the American black bear living in the Central and North Coast regions of British Columbia, Canada. Most Kermode bears are black but there are about 100-500 white individuals. So they are white Black bears...often called spirit bears. https://en.wikipedia.org/wiki/Kermode_bear

Elvis is Back!

This is not real evidence but it's very interesting, and related. -High-quality genome sequences for some of the great apes have been assembled using state-of-the-art sequencing tools. The assemblies provide an unbiased comparison between humans and their closest evolutionary relatives. https://www.nature.com/articles/d41586-018-05679-9

I learned that pit vipers have infrared sensing organs...so they can detect warm-blooded animals at night.https://en.wikipedia.org/wiki/Pit_viper

Heisenberg! Neuron joke!

Today I learned vampire bats can sense infrared to detect birds and mammals at night. Their entire nutrition relies on blood from mammals or birds. https://en.wikipedia.org/wiki/Vampire_bat https://en.wikipedia.org/wiki/Infrared_sensing_in_vampire_bats
