Researchers take major step towards creating synthetic embryo-like structures that mimic real human embryos | Science & Tech News
admin
Researchers have taken a major step towards creating synthetic embryo-like structures that mimic real human embryos with most of the fundamental features of the earliest stages of life. The latest study, from researchers at the Weizmann Institute in Israel, built on the work of a number of recent experiments using human embryonic stem cells and…

Human shoulders and elbows evolved as brakes for apes climbing trees, new study says | World News
admin
Humans’ rotating shoulders and extending elbows – which allow us to reach a high shelf or throw a ball – may have evolved as a natural braking system for our primate ancestors, new research suggests. Early humans needed the movements to slow their descent out of trees so they could climb down without dying, researchers…

Pig kidney keeps working in human body for over a month | Science & Tech News
admin
A genetically modified pig kidney transplanted into a brain-dead patient over a month ago is still working normally, researchers have found. The procedure was carried out by a team of surgeons in New York on 14 July, and researchers are now tracking the kidney’s performance for a second month. It is the longest period a…

Earth moves closer to Anthropocene epoch as surface shows indelible impact of human activity | Science & Tech News
admin
Scientists are a step closer to officially declaring a new geological time period that marks the start of humanity’s irreversible impact on the planet. How to define the start of the Anthropocene epoch, which would need to be visible in layers of rock in millions of years’ time, has proved controversial. Although humans began to…

Scientists create synthetic human embryos using stem cells in major breakthrough | Science & Tech News
admin
Scientists have created synthetic human embryos using stem cells in a major scientific breakthrough Experts believe the development could provide insight into causes of miscarriages and unique aspects of human development but also raises ethical and legal questions. Professor Magdalena Zernicka-Goetz, from the University of Cambridge and California Institute of Technology, described fostering the embryos…

Lucy, the world’s most famous human ancestor, could walk just like us, new research suggests | Science & Tech News
admin
The world’s most famous early human ancestor could walk upright like a modern-day human thanks to fully bendable knee joints, research suggests. ‘Lucy’ was from an extinct ape-like species that lived in Africa more than three million years ago. She was dug up in Ethiopia in 1974, and at the time was the most complete…

AI drone ‘kills’ human operator during ‘simulation’ – which US Air Force says didn’t take place | Science & Tech News
admin
An AI-controlled drone “killed” its human operator in a simulated test reportedly staged by the US military – which denies such a test ever took place. It turned on its operator to stop it from interfering with its mission, said Air Force Colonel Tucker “Cinco” Hamilton, during a Future Combat Air & Space Capabilities summit…

300,000-year-old human footprints discovered in Germany | Science & Tech News
admin
Scientists have discovered human footprints thought to be 300,000 years old and the earliest ever found in Germany. Experts believe the perfectly-preserved prints were left by a family of Heidelberg people, a long-extinct species of human. The footprints were discovered in the Schöningen Paleolithic site in the Harz Mountains. Ancient animal prints, including the first…

DNA inherited from Neanderthals may impact human nose shape, study finds | Science & Tech News
admin
The shape of modern human noses may be partly determined by genetic material inherited from Neanderthals, according to a new study. Neanderthals were an ancient species who lived in Eurasia until their extinction about 40,000 years ago. But scientists believe they interbred with homo sapiens – meaning some of their DNA remains in modern-day humans.…
