“In corticospinal injuries using a mouse model, adult neurons begin a natural regeneration by revertiprocessng back to an embryonic state and that regeneration is sustained by a surprising gene.”

When adult brain cells are injured, they revert to an embryonic state, according to new findings published in the April 15, 2020 issue of Nature by researchers at University of California San Diego School of Medicine, with colleagues elsewhere. The scientists report that in their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

PCs, tablets, 5G-powered live streams, and cloud platforms are all expected to see more demand from the education sector in China, with the coronavirus outbreak accelerating a digital shift, according to a report from research firm IDC China.

Via Harvard David A. Sinclair “The coronavirus is part bat & part human virus. A new study says the Frankenstein event happened well before its transmission to humans. Wait, what? Humans first infected bats?

The intermediate Frankenstein coronavirus has part human/part bat versions of the spike protein (the knobs on the outside of the virus & what COVID-19 vaccines target). Coronafrankenstein is formally called RaTG13, the name, rank & serial # of a horseshoe bat sample. If we gave bats coronavirus first, then people, including scientists, should stay away from bats especially if they don’t feel well. That’s why, as much as I like cats, I don’t like how they can catch it from us. It’s a potentially vicious cycle.

The new study says a mutation has changed the spike protein of an Indian strain of coronavirus that likely reduces its ability to transmit, but “raises the alarm that the ongoing vaccine development may become futile in future epidemics” like seasonal flu.”

Monitoring the mutation dynamics of SARS-CoV-2 is critical for the development of effective approaches to contain the pathogen. By analyzing 106 SARS-CoV-2 and 39 SARS genome sequences, we provided direct genetic evidence that SARS-CoV-2 has a much lower mutation rate than SARS. Minimum Evolution phylogeny analysis revealed the putative original status of SARS-CoV-2 and the early-stage spread history. The discrepant phylogenies for the spike protein and its receptor binding domain proved a previously reported structural rearrangement prior to the emergence of SARS-CoV-2. Despite that we found the spike glycoprotein of SARS-CoV-2 is particularly more conserved, we identified a mutation that leads to weaker receptor binding capability, which concerns a SARS-CoV-2 sample collected on 27^th January 2020 from India. This represents the first report of a significant SARS-CoV-2 mutant, and raises the alarm that the ongoing vaccine development may become futile in future epidemic if more mutations were identified.

Another warning from the WHO to not treat coronavirus, but wait for a vaccine that does not even exist. The World Health Organization (WHO) reported on its site that it is not advised to take any herbal remedies to treat #COVID19, and in India Prime Minister Narendra Modi warned alternative healers they should not boast they have a cure for the virus, only remedies to assist with symptoms.

Between the summer of 1665 and the spring of 1667, Isaac Newton developed his theories on calculus, optics, and the laws of motion and gravity. He was quarantining during the Bubonic Plague and found the extra time on his hands gave him the freedom to pursue intellectual endeavors his day-to-day duties may have otherwise squandered.

Nearly 400 years later, history could be repeating itself.

With decades of work at the intersection of time, space, and elementary particles under his belt, Stephen Wolfram believes he’s close to discovering how the universe works—or, at least, the fundamental law of physics that makes all of our other laws of physics tick. So the 60-year-old computer scientist, businessman, and physicist has launched “The Wolfram Physics Project” to crowdsource that work with some of the best minds in the world.

Humans and all other living things have DNA, which contains hereditary information. The information in your DNA gives your cells instructions for producing proteins. Proteins drive important body functions, like digesting food, building cells, and moving your muscles.

Your DNA is the most unique and identifying factor about you—it helps determine what color your eyes are, how tall you are, and how likely you are to have certain health problems. Even so, over 99% of DNA sequences are the same among all people. It is the remaining 1% that explains much of what makes you, you!

DNA is arranged like two intertwined ropes, in a structure called a double helix (see figure 1). Each strand of DNA is made of four types of molecules, also called bases, attached to a sugar-phosphate backbone. The four bases are adenine (A), guanine (G), cytosine ©, and thymine (T). The bases pair in a specific way across the two strands of the helix: adenine pairs with thymine, and cytosine pairs with guanine.
