When cancer cells break away from a primary tumor and migrate to other organs, this is called metastatic cancer. The organs affected by these metastases, however, depend in part on their tissue of origin. In the case of breast cancerusually form in the bones. In an attempt to identify what determines the organs affected by … Read more
The second line of defense of the immune system, T cells, has been shown to be highly effective in recognizing and counteracting the Coronavirus Omicron variant, in most cases preventing it from reaching the critical phase of Covid-19. This is shown by the results of laboratory tests in South Africa, Reuters reported, quoted by BNR. … Read more
– – PHOTO: Pixabay – Japanese scientists have successfully tested vaccines against cells that contribute to the aging process. Scientists say they may have taken a step toward achieving the goal of human longevity. In laboratory studies, a vaccine targeting proteins contained in old cells – those that have stopped multiplying naturally – slows the … Read more

Chemists from the United States have created cell-like structures that can selectively capture various substances and particles, transport them … Read more
While the pandemic has still not been contained, scientists continue to seek to better understand what causes the most severe cases of Covid-19. They could, this time, have identified a key molecular mechanism responsible for its mortality.

Spanish researchers discovered that a gene present in the cells that surround tumors, and that form the so-called tumor stroma, is key in the progression of breast cancer. Details of the finding have been published in Cancer Research. Led by researchers from the Higher Council for Scientific Research (CSIC) and the Complutense University of Madrid … Read more

The code was previously written on a computer and synthesized. Microbiologists at the Venter Institute in the United States have created a synthetic cell of a primitive type and found … Read more
– – COVID-19 directly infects the oral cavity PHOTO: Reuters – The new coronavirus infects cells in the mouth and saliva, which is why some people experience symptoms such as loss of taste, dryness and rashes in the mouth, Maylonline reported. The oral cavity also plays a role in transmitting the virus to the lungs … Read more
According to the journal “Nature”, two scientific groups from the United States Australia have developed cell structures similar to human ones from embryonic stem cells or cells reprogrammed in the laboratory. According to the magazine, these are “human embryo precursors” that were generated without using in vitro fertilization. These structures are similar to so-called blastocysts. … Read more
ATLAS SPAIN Updated:03/18/2021 09: 06h Keep Without the need to unite sperm and egg, a group of scientists has achieved what seemed impossible: create a model of a human embryo. It sounds like science fiction, but it is already a reality, thanks to the work of Monash University researchers. And they have done it using … Read more
