Individual neurons could recognize, for example, when we are about to touch our tongue to our palate to say the letter D * This will enable the development of prostheses for those suffering from speech problems
Mouse, rabbit and human embryos (right to left) in the same developmental stage - gastrulation (days 8-7.5 of pregnancy in rabbits and mice and around day 18 of development in humans). At this stage the human, rabbit and other vertebrate embryos are almost flat disc-shaped, while the mouse embryo is elongated cylinder-shaped. The images of the mouse and rabbit embryos were created as part of the current study, the image of the human embryo is taken from a study published in 2021 (Richard CV Tyser et al. Single-cell transcriptomic characterization of a gastrulating human embryo. Nature 600: 285-289)

In the rabbit hole

The institute's scientists developed a method that allows real-time monitoring of the development of embryos at the beginning of their journey and applied it for the first time to rabbits. The comparison they made between embryonic development in rabbits and mice gave rise to answers to fascinating questions about the formation of humans

Eureka moments, strange discoveries and super plants

Thanks to an accidental discovery in the laboratory, researchers were able to improve plant growth and give them resistance to drought and salinity conditions, by exposing their seeds to a plant hormone in a simple and easy-to-apply process
Canaanite finds from Megiddo Hill (courtesy of Megiddo Archaeological Expedition)

Researchers have analyzed the genetics of the Canaanites and its relationship to modern populations such as Jews, Palestinians and Bedouins

The DNA analysis showed that the Canaanites were created from the mixing of populations that migrated to the southern Levant mainly from the Caucasus region (or western Iran) with ancient local populations that stayed there, a process that lasted at least 1,000 years

Every dog has its day? The people who hesitate to vaccinate their dogs

A new study reveals that about half of Americans are afraid to vaccinate their dogs, thereby risking the spread of rabies and other diseases that can harm the animal - and humans. And what is the situation in Israel?

A mechanism has been discovered that causes sleep apnea in sick children

  • No comments
One of the diseases resulting from such mutations in the PHOX2B gene is the disease CCHS. This is a rare and life-threatening syndrome in which babies, children and adults stop breathing as soon as they fall asleep. The patients must be connected to ventilators in order not to die in their sleep
