Dogs cry tears of joy when reuniting with their owners.
Pet dogs produce a larger volume of tears when they are reunited with their owners than with acquaintances, possibly because of surging oxytocin levels—findings that could be the first evidence of emotional crying in nonhuman animals.
The stimulations were critical for their learning. Separate experiments with DishBrain without any electrical feedback performed far worse.

The study is a proof of concept that neurons in a dish can be a sophisticated learning machine, and even exhibit signs of sentience and intelligence, said Kagan. That’s not to say they’re conscious—rather, they have the ability to adapt to a goal when “embodied” into a virtual environment.
Sponsored by Kishore Tipirneni’s new book “A New Eden” available here: https://getbook.at/NewEden | Abiogenesis – origin of life. Living matter from non-living matter. The origin of living organisms from inorganic or non-living material is called abiogenesis. But abiogenesis is not evolution.
Despite the incredible variations of life we see today, at the fundamental level, all living things contain three elements: Nucleic acids, Proteins, and lipids. These three things had to have been present in order for life to start.
The most important component may have been lipids which make up the cell walls because without a way to encapsulate certain elements, they various chemicals could not come together to potentially interact.
Lipids molecules have a unique structure. The round part loves water. The tail part hates water. So it has a tendency to self-assemble into natural spheres. However, when there are certain salt ions present, it destroys the lipid spheres. But RNA and other functions of a cell require salts and other ions. However, researchers at the University of Washington showed that lipid spheres do not disassemble if they are in the presence of amino acids, precursor to protein molecules. So it turns out that lipid cell walls and proteins need each other to exist, in salty water.
Recreates the immune system;…Prolonged fasting forces the body to use stores of glucose, fat and ketones, but it also breaks down a significant portion of white blood cells. Longo likens the effect to lightening a plane of excess cargo. During each cycle of fasting, this depletion of white blood cells induces changes that trigger stem cell-based regeneration of new immune system cells. In particular, prolonged fasting reduced the enzyme PKA, an effect previously discovered by the Longo team to extend longevity in simple organisms and which has been linked in other research to the regulation of stem cell self-renewal and pluripotency — that is, the potential for one cell to develop into many different cell types. Prolonged fasting also lowered levels of IGF-1, a growth-factor hormone that Longo and others have linked to aging, tumor progression and cancer risk.
A simulated version of Paris where universities and telecommunication hubs are connected by a quantum communication network suggests that existing technology is already nearing the ability to create functional “quantum cities”.
The study shows how deep learning can be used to detect cell image analysis.
Researchers have found a way to observe cell samples to study morphological changes — or the change in form and structure — of cells. This is significant because cells are the basic unit of life, the building blocks of living organisms, and researchers need to be able to observe what could influence the parameters of cells, such as size, shape, and density.
Conventionally, cell samples were observed directly through microscopes by scientists to observe and discover any changes of the cells. They would look for morphological changes in the cell structures.
