Kimmie Gilbert couldn't seem to lose weight despite trying diets, exercise, and medication. Research suggests that gut microbiome composition might play a role in a person's weight. AdvertisementKimmie Gilbert has one pressing question: "What in the world are y'all eating that I'm not eating that causes y'all to lose weight and not me?" In 2019, health tech had a global market value of approximately $350 billion, according to McKinsey. A microbe called Prevotella, which is associated with weight loss, wasn't found at all in her gut.

On Thursday, Seed Health launched CODA, a computational biology platform funded by its consumer business profitability. Seed Health has been in the business of microbiome scientific breakthroughs since its founding in 2015, but its biggest success to-date may have been becoming profitable as a bioscience startup. Katz's co-founder and co-CEO at Seed Health, Raja Dhir, said CODA and the accompanying data set will help to standardize microbiome science methods, which has long been an issue in the field. CODA's first applications are in metabolic health, brain health, longevity, and menopause, research areas chosen because they have already been identified as areas of human health where early CODA data displayed the strongest evidence. Seed Health has been working on several efforts around pioneering microbiome science for human and planetary health, and many in the field believe the approach is destined to have wider applications.

CNN —Scientists based in China have created a monkey chimera with two sets of DNA, experimental work they say could ultimately benefit medical research and the conservation of endangered species. It’s the world’s first live birth of a primate chimera created with stem cells, the researchers said. Scientists have created mouse embryos that are part human, and in 2021, scientists reported that they had grown human-monkey chimeric embryos. In September, researchers reported that they had grown kidneys containing mostly human cells inside pig embryos. Then they selected a subset of cells to inject into genetically distinct 4- to 5-day-old embryos from the same monkey species.

☆ Lab models of human embryos raise hopes and concerns
▼ + stars: | 2023-10-26 | by ( Katie Hunt | ) edition.cnn.com time to read: +14 min

From the moment sperm fuses with an egg, human embryo development involves a string of complex and little understood processes. What happens during human embryo development, particularly in the crucial first month, remains largely unknown. However, 14 days is an important milestone because it is when permitted lab research on cultured human embryos routinely ends. He said, in the future, it might be possible to go as far as 40 days with human embryo models. Some in the field envision a “tipping point” wherein human embryo models might be afforded some protection like those surrounding human embryos, as scientific advances diminish the differences between the embryo models and their real-life counterparts.

☆ Israeli scientists create model of human embryo without eggs or sperm

The Israeli team emphasised that they were a long way from being able to create an embryo from scratch. "The question is, when does an embryo model become considered an embryo? At the moment we are really, really far off from that point," said team leader Jacob Hanna. "None of these models fully recapitulate natural human development but each adds to ways in which many aspects of human development can now be studied experimentally," she said. The study raises some ethical questions over the possibility of potential future manipulation in human embryo development, Hanna and others noted.

REHOVOT, Israel (Reuters) - Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic development. "The question is, when does an embryo model become considered an embryo? At the moment we are really, really far off from that point," said team leader Jacob Hanna. "None of these models fully recapitulate natural human development but each adds to ways in which many aspects of human development can now be studied experimentally," she said.

Scientists used stem cells to create a model of an embryo in the lab without sperm or egg. Researchers brought us one step closer to understanding those early days by making a model of a human embryo in the lab, without using sperm or eggs. How scientists grew a model human embryo without a sperm or eggAn illustration of embryonic stem cells. Stem cells are cells that form other, more complex cell types depending on what messages the body sends them. Starting with stem cells, the researchers turned them into types of cells that make up a human embryo, from placenta to fetus.

☆ Scientists Debut Lab Models of Human Embryos

In its first week, a fertilized human egg develops into a hollow ball of 200 cells and then implants itself on the wall of the uterus. Over the next three weeks, it divides into the distinct tissues of a human body. And those crucial few weeks remain, for the most part, a black box. Dr. Hanna and a number of other biologists are trying to uncover those details by creating models of human embryos in the lab. They are coaxing stem cells to organize themselves into clumps that take on some of the crucial hallmarks of real embryos.

☆ Pentru prima dată în istorie, masa tuturor construcţiilor realizate de oameni depăşeşte biomasa
▼ + stars: | 2020-12-10 | by ( Publika.Md - Aici Sunt Știrile | ) www.publika.md time to read: 1 min

Masa tuturor construcțiilor artificiale realizate de oemeni - clădiri, șosele, aparatură etc. - va depăși după 2020 masa totală a întregii materii vegetale și animale de pe Pământ, informează Agerpres, care citează un studiu publicat de revista Nature. Cercetarea, realizată de Weizmann Institute of Science din Israel, susţine că omenirea şi Pământul se află la „un moment de cotitură” în 2020, când masa întregii materii produse de om a ajuns egală cu masa florei şi faunei, cum ar fi copacii, plantele, animalele, bacteriile şi ciupercile. Institutul estimează că masa materiei produse de mâna omului va fi de două ori mai mare decât cea a biomasei până în 2040. Până atunci, „jungla” din beton, oţel şi plastic creată de oameni este preconizată să cântărească cel puţin două teratone.

Institutul estimează că masa materiei produse de mâna omului va fi de două ori mai mare decât cea a biomasei până în 2040. Până atunci, jungla din beton, oțel și plastic creată de oameni este preconizată să cântărească cel puțin două teratone. Acesta a spus că studiul este, după știința sa, primul care compară masa fabricată de om cu biomasa. Rezultatele cercetării „demonstrează cât de mult s-a extins amprenta noastră globală peste măsura de la pantof”, a spus Milo. „Sperăm că odată ce avem toate aceste date șocante în fața ochilor, putem, ca specie, să ne asumăm responsabilitatea”, a mai spus acesta.
