A single neuron can encode information from two different sounds
A single neuron can encode information from two different sounds by switching between the associated signals at different firing rates. Our brains are capable of processing multiple stimuli at once. Our working memory is constrained to around 5 to 7 items.
Senolytic drugs selectively eliminate senescent cells which affect neighboring ones. A combination of two senolytic drugs extended life span and gave better health to aging mice. Additional research is necessary with the compound in clinical trials with people.
Giant neurons found in the nucleus gigantocellularis
Giant neurons found in the nucleus gigantocellularis (NGC), with links to virtually the entire nervous system could be essential for the initiation of any behavior. They are crucial to wake up the brain in the morning and participate in the general arousal in animals and humans, keeping us aware and in touch with ourselves and our environment.
A profusion of microorganisms has been identified in the ocean
A profusion of microorganisms has been identified in the ocean twilight zone, between 100 and 1000 meters below the surface. They consume carbon-rich particles sinking to the seabed. Only one family of organisms consuming up to 20% of the particles sinking, they could all play a far more outsized role in the carbon cycle than previously believed.
The epithelial cells, in skin and internal organs, resemble column-like prism or bottle shape of a truncated pyramid. But when the curvature of the tissue increases a more energy-efficient new shape appears, called scutoid. It looks like a prism with one end having five edges and the other six.
The transport system inside our cells uses motor proteins
The transport system inside our cells uses motor proteins which walk along tracks. Each cell has a cytoskeleton made up of filaments. These filaments provide structural support for the cell and tracks for the proteins. Microtubules are one type of tracks used for long-distance transport. Actin is another one used for short-distance delivery.
The most common transposon accounts for 24% of the human genome.
The most common transposon, LINE1, accounts for 24% of the human genome. This gene which was considered as a dangerous and disease-causing parasite is necessary for embryos to develop after the two-cell stage. Its RNA form a complex with gene regulatory proteins in the cell nucleus.
(73aH*) : August 6th is the anniversary of the atomic bomb explosion on Hiroshima in 1945.
This date represents the entrance of Humanity into the age of Revelation (Apocalypsis).
Thus, since August 6, 2018, we are in 73 aH, (meanning 73 after Hiroshima).
It is also an “atheist” and universal calendar to replace the existing ” monotheist”, religious and non universal calendars.
