An Israeli laboratory has grown synthetic mouse embryos with a beating brain and heart — in an egg-free sperm-free procedure that uses stem cells taken from the skin. The breakthrough, published Monday in the peer-reviewed journal Cell, is the first time advanced embryos of any species have been made from stem cells alone, said cell biologist Prof. Jacob Hanna of the Weizmann Institute of Science told The Times of Israel. . Hanna, who led the research, said that previous efforts have only led to blastocysts, meaning structures formed early in mammalian development. Blastocysts have a fraction of the millions of more cells present in their embryos. “Excellent,” he commented. “No sperm, no eggs and no uterus, but we managed to get embryos formed from stem cells alone for up to eight days – a third of the gestational age of mice – with beating hearts.” He said the research could one day be used to grow artificial human embryo-like structures to produce cells for futuristic medical sol

In the skin affected by colitis, the bacteria remain the same, but the number of immune cells is greater, creating inflammation. Image by Scharschmidt Lab. A new study by UC San Francisco researchers reveals how intestinal inflammation can irritate not only the digestive system, but the skin as well. It’s a story in which the main players are specialized immune cells and the community of bacteria – called the microbiome – that resides in the gut and skin. Scientists are becoming increasingly aware that disruptions to the gut microbiome can affect other parts of the body. These changes have been linked to an increased risk of diseases such as asthma, rheumatoid arthritis, multiple sclerosis. In a study published May 31, 2022 in Cell Reports, a team of researchers investigated how colitis, or chronic inflammation of the colon, can cau

Model struggling with severe acne reveals ‘secret’ weapon she used to achieve ‘glassy smooth skin’ in just six months: ‘You can thank me later’ Model Jordan Simek has shared her skin-changing skincare routine Aussie youth struggles with acne and redness for years She started using Secret Skin Care and saw her skin change ‘Your skin will thank me later, I promise,’ he said next to a snap of his face By Laura House For The Australian Daily Mail Published: 00:29 EDT, 7 July 2022 | Updated: 04:42 EDT, 7 July 2022 An Australian model has shared a ‘secret’ weapon that has cleared her acne and redness and left her with ‘glassy smooth’ skin in just six months. Jordan Simek, from Sydney, has finally revealed that he’s been using Secret Skin Care after ‘gatekeeping’ his routine for a while – and the results speak for themselves.

A study of the herpes virus infecting chickens offers new insight into the potentially problematic interactions between vaccines made from live viruses and viruses that are meant to be thwarted. Reported in the journal Virulence, the study offers direct evidence that vaccines and viruses can infect the same cells in live animals and share the molecular tools that allow the virus to infect other animals – in this case, chickens. The study focused on Marek’s disease, a viral infection that is spread when a chicken inhales flakes of dead skin or feather tissue from an infected chicken. “We’ve been trying to understand how the virus spreads from one host to another,” said University of Illinois Urbana-Champaign pathobiology professor Keith Jarosinski, who led the study. “Not only did we do it for the benefit of chickens in the poultry industry, but also because of a very similar mechanism used by the virus that causes chickenpox, where it enters through the respiratory tract and infects l
