Gene-edited babies and cloned monkeys: China tests bioethics

A Chinese scientist's claim that he created the world's first genetically-edited babies has shone a spotlight on what critics say are lax regulatory controls and ethical standards behind a series of headline-grabbing biomedical ...

Embryos remember the chemicals that they encounter

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent ...

Not junk: 'Jumping gene' is critical for early embryo

A so-called "jumping gene" that researchers long considered either genetic junk or a pernicious parasite is actually a critical regulator of the first stages of embryonic development, according to a new study in mice led ...

The misleading evidence that fooled scientists for decades

There are surprisingly few proven facts in science. Instead, scientists often talk about how much evidence there is for their theories. The more evidence, the stronger the theory and the more accepted it becomes.

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 ...

Researchers obtain chicken embryo development data

KFU Extreme Biology Lab and RIKEN have uncovered new facts about chicken embryo growth, which may lead to similar discoveries about humans. The work is published in PLOS Biology.
