Model embryo with heartbeat replicates cells in early pregnancy
Exclusive: Scientists used stem cells to create the structures, which were unable to develop into a foetusScientists have created a model human embryo with a heartbeat and traces of blood in an advance that offers an extraordinary window into the first weeks of life.The synthetic structure, created from human stem cells without the need for eggs, sperm or fertilisation, replicated some of the cells and structures that would typically appear in the third and fourth week of pregnancy. But it was specifically designed to lack the tissues that go on to form the placenta and yolk sac in a natural embryo, meaning that it did not...

The Guardian view on stem cells and embryos: creating life ’s likeness in a lab | Editorial
New technology raises hopes and ethical dilemmas. Society will have to work out what it thinksScience often moves faster than moral thought progresses, leaving the public disoriented and exposing the limits of legislators ’ imagination. Many people will be struggling to make sense of the astonishing breakthroughs presented at this week’s International Society for Stem Cell Research’s (ISSCR)annual meeting in Boston. Thework by Prof Magdalena Żernicka-Goetz, of Cambridge University and the California Institute of Technology, creating human embryo-like models from stem cells, without the need for eggs or sperm, raises...

Two epilepsy patients ’ seizures greatly reduced in stem cell therapy trial
Early results show promise in trial involving injection of lab-grown inhibitory neurons into brainThe first two epilepsy patients to receive an experimental stem cell therapy experienced an almost complete reduction in seizures a year after treatment, early trial results show.The therapy involves a single brain injection of lab-grown neurons that are designed to dampen electrical activity with the aim of stopping seizures. It is too early to confirm whether approach is effective but the initial results, presented at the International Society for Stem Cell Research ’s annual meeting in Boston last week, are viewed as extr...

Biologists create detailed lab replicas of early human embryos
Biologists trying to create laboratory models of the early growth of a human embryo have taken a major step forward. In preprints posted online on Thursday and Friday, four research teams reported using various kinds of human stem cells, some genetically modified, to create ersatz embryos that closely resemble real embryos that are up to 14 days old, replicating a period in human development that is very difficult to study.
The rush of papers was triggered when the leader of one group, developmental biologist Magdalena Zernicka-Goetz, briefly described her team’s results at the International Society for Stem Cell R...

Advances in synthetic embryos leave legislators needing to catch up
Analysis: As the science outpaces the law, scientists should proceed cautiously and clear boundaries must be setSynthetic embryos sit at a unique juxtaposition: scientifically fascinating, ethically challenging and, for the most part, entirely unregulated by current legislation. Thelatest work by Prof Magdalena Żernicka-Goetz’s team brings these issues into stark relief and show that developments in this field are happening so quickly that the science is rapidly outpacing the law.The motivation for creating embryo models in the lab is relatively uncontroversial. For the avoidance of doubt, there are no plans to create l...

Crops grown without sunlight could help feed astronauts bound for Mars
Riverside, California—
For the first astronauts to visit Mars, what to eat on their 3-year mission will be one of the most critical questions. It’s not just a matter of taste. According to one recent estimate, a crew of six would require an estimated 10,000 kilograms of food for the trip. NASA—which plans to send people to Mars within 2 decades—could stuff a spacecraft with prepackaged meals and launch additional supplies to the Red Planet in advance for the voyage home. But even that wouldn’t completely solve the problem.
Micronutrients, including many vitamins, break down over months and will need to...
