Genome editing reveals role of gene important for human embryo development


Researchers have used genome editing technology to reveal the role of a key gene in human embryos in the first few days of development. This is the first time that genome editing has been used to study gene function in human embryos, which could help scientists to better understand the biology of our early development.

Three policies to improve children's language development


Bilingual children from low-income homes are at greater risk of falling behind their peers in developing the appropriate language skills for their age group, leading to poorer academic achievement over time. A new article addresses how inequality impacts children’s language development and details policies that can intervene.

Gravity, 'mechanical loading' are key to cartilage development


Mechanical loading is required for creating cartilage that is then turned to bone; however, little is known about cartilage development in the absence of gravity. Now, bioengineers have determined that microgravity may inhibit cartilage formation. Findings reveal that fracture healing for astronauts in space, as well as patients on bed rest here on Earth, could be compromised in the absence of mechanical loading.
