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 development by Weizmann Institute of Science scientists makes it possible to predict what the smell of any molecular compound will be and may pave the way for the digitization and reproduction of smells
Regional map of average symptoms characterizing COVID-19. Shown are areas in different cities where there are at least 30 respondents, or neighborhoods with at least 10 respondents to the questionnaire. Each area is colored according to a category determined according to the average amount of symptoms reported by the respondents in that area. Green - low percentage of symptoms, red - high percentage of symptoms

Dr. Oren Raz came up with an idea for a new way to circumvent the phase reconstruction problem: to combine two ultra-fast laser flashes and measure them together, so that the combination between the two would act as a hologram

The shape of the flash - how to measure a very fast phenomenon using a much slower detector

In the figure: networks with a homogeneous structure (A) differ from heterogeneous networks (B) in their ability to adapt to changes through improvisation. In networks of the first type (homogeneous), each vertex affects a limited number of other vertices. As a result, chaotic dynamics are created and the search process (exploration) does not converge to a stable state. In the heterogeneous networks, on the other hand, some of the vertices (marked as large circles) affect large parts of the network and create dynamics leading to a steady state.
