As long as you have problems posting, I would recommend using a “throwaway” account to do your posting so you never lose your main account. A few months ago, I actually got 2 of my “throwaway” accounts UNBANNED. It is cool when you end up gaining accounts instead of losing them.

S timeline but they almost never complain recently.

The weekend release of the US Central Intelligence Agency (CIA) report favouring a laboratory leak as the likely origin of COVID-19 – albeit with “low confidence” – has reignited a vitriolic debate.

On the one side of the divide are those who argue that SARS-CoV2, the virus causing COVID-19, originated from a lab leak from the Wuhan Institute of Virology (WIV) that was studying coronaviruses in bats.

Some researchers who favour the lab-leak thesis argue that the virus contains unusual features that indicate it may have been genetically modified by humans. These focus on the virus’s furin cleavage site, a strange feature on the spike protein of the virus that is not present in other coronaviruses, that cast doubt on whether the virus had evolved naturally.

“ tabindex=”0” amino acids and incorporated sulfur-based compounds much earlier than previously thought. This challenges long-standing experiments and opens the door to the possibility that extinct genetic codes existed before ours.

Cracking the Code of Life’s Origins

Despite awe-inspiring diversity, nearly all life on Earth — from tiny bacteria to massive blue whales — shares the same genetic code. But exactly how and when this code emerged remains a topic of scientific debate.

A study reveals DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Panzeri et al. use a Trim28 +/D9 mouse model with intrinsic developmental heterogeneity to show that ‘heavy’ and ‘light’ developmental morphs exhibit different timing, type and severity of cancer, linked to a relevant DNA hypomethylation signature.
