During #development, distal visceral #endoderm (DVE) cells migrate to shape A-P axis specification. @m-stower.bsky.social @srinivas-lab.bsky.social &co reveal the role of Ca2+ dynamics in this, showing that inhibition of #calcium transients causes DVE arrest @plosbiology.org 🧪 plos.io/4nHWxF4
Epiblast Ca2+ waves propagate from the apical to basal domain. The images show selected time points from movies of E5.5 GCaMP6f embryos imaged using a ZEISS lattice light-sheet 7 microscope. Top row: An example of an epiblast wave involving a large proportion of the tissue captured by imaging a volume of the embryo at 20-s intervals. A total of 9/16 embryos showed at least one epiblast Ca2+ wave. Bottom row: Faster imaging at 5-s interval revealed that the Ca2+ wave in the epiblast can be preceded by a transient in a neighboring VE cell—this was observed in 5/19 events from 9 embryos (white arrowheads).

Visa costs will limit Britain's ability to court those who may seek to leave the U.S. after Trump's administration cut funding for universities and research bodies, says Professor Alison Noble FRS, Foreign Secretary of the Royal Society: www.reuters.com/world/uk/hig...

High UK visa costs deter international scientists and engineers
It took Ed Roberts over a year to find a senior scientist to work at his cancer research laboratory in Scotland, a delay he blames on high UK visa costs that made it harder to attract international workers.

Have always been fascinated about these elusive giants–the beaked whales. Until now nothing was known about this extant species; known from only seven records and have never been seen alive at sea. Turns out it has a nine-chambered stomach and vestigial teeth! www.doc.govt.nz/news/media-r...
