Scientists create model of an early human embryo from skin cells

In a discovery that will revolutionize research into the causes of early miscarriage, infertility and the study of early human developmentā€”an international team of scientists led by Monash University in Melbourne, Australia ...

Turning off 'junk DNA' may free stem cells to become neurons

For every cell in the body there comes a time when it must decide what it wants to do for the rest of its life. In an article published in the journal PNAS, NIH researchers report for the first time that ancient viral genes ...

Human embryo-like model created from human stem cells

Scientists from the University of Cambridge, in collaboration with the Hubrecht Institute in The Netherlands, have developed a new model to study an early stage of human development, using human embryonic stem cells. The ...

Can plants tell us something about longevity?

The oldest living organism on Earth is a plant, Methuselah a bristlecone pine (Pinus longaeva) that is over 5000 years old. Conversely, animals only live up to a few hundred years. Can we learn something from plants about ...

How human brain development diverged from great apes

Researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, Institute of Molecular and Clinical Ophthalmology Basel, and ETH Zurich, Switzerland, have presented new insights into the development ...

'Nanofiber yarn' makes for stretchy, protective artificial tissue

The human body is held together by an intricate cable system of tendons and muscles, engineered by nature to be tough and highly stretchable. An injury to any of these tissues, particularly in a major joint like the shoulder ...

A first look at the earliest decisions that shape a human embryo

The factors that shape the destiny of a cell, like that of a fully formed person, remain something of a mystery. Why, for example, does one stem cell in a human embryo become a neuron rather than a muscle cell? And why does ...
