For some reason the mouse-over for this link on the wikipedia page for SQL shows the page for an embryo. 😆 (the link itself is correct)

A new map of arthropod evolution, from #fossils to #embryos

New study sheds light on how #insects, #spiders, #crustaceans, and other #arthropods evolved their distinct body structures. By tracing these patterns back to ancient embryonic processes, the research uncovers a deep evolutionary logic behind the segmented #bodyPlans that define the world’s most diverse animal group.

Deciding the fate of “leftover” #embryos
It’s not always easy to choose whether to store, donate or discard extra #IVF embryos.
No one knows for sure how many embryos are frozen in storage tanks, but the figure is thought to be somewhere between 1 million and 10 million in the US alone. Some of these embryos have been in storage for years or decades. In some cases, the intended parents have deliberately chosen this, opting to pay hundreds of dollars per year in fees.

Trump #executiveorder declaring only ‘two #sexes’ gets the #biology wrong, #scientists say .

Order describes sex as an ‘immutable biological classification set at conception as either #male or #female’, but all #human #embryos start out as #female.

#SarahMcBride points out #fatalflaw in Trump’s #executiveorder: ‘He just declared everyone a #woman’

All #human #embryos follow a “#female” #developmental #path until the activation of the #SRY #gene several weeks after #conception, which sparks #sexualdifferentiation.

#Donating #embryos for #research is surprisingly complex

The UK is seen as a global leader in regulating #reproductive #technologies. Some worry that onerous paperwork is causing embryos to be wasted.

Guidelines on lab-grown embryo models are strong enough to meet ethical standards — and will build trust in science

The UK code of practice for researchers working with stem-cell-based embryo models is designed to both reassure the public and provide valuable guidance to researchers.

A friend in Silicon Valley mentioned that a lot of her friends have had October babies in recent years. It's because copays & other insurance stuff resets every year. So, IVF in January, babies in October.

"Dozens of labs around the world are striving to grow models of human embryos to study development, fertility and therapies. They are entering uncharted ethical territory."

#US #startup charging couples to ‘screen #embryos for #IQ’
#Heliospect’s services were marketed at $50,000 for 100 embryos. Managers boasted they could produce gain of more than 6 IQ points. Selecting embryos for high IQ is not permitted under #UK law. While legal in US, where #embryology is more loosely regulated, IQ screening is not yet commercially available there.
Leading #geneticists and #bioethicists said the project raised a host of moral and medical issues.

Since then, ≥4 of #Alabama’s 7 #fertility clinics have hired #biotech cos to move the cells elsewhere. A 5th clinic is working w/a doctor in NY to discard #embryos bc of concerns about the legality of doing so in AL.

Fertility patients outside of AL, too, are worried about how their embryos…might one day be affected by lawmakers who believe human life begins at conception. Since #SCOTUS’ 2022 decision to overturn #RoeVWade, 14 states have passed total or near total #abortion bans.

A court ruling that deemed #FrozenEmbryos “children” has motivated some patients & clinics to move embryos out of #RedStates.

The embryo migration is most striking in #Alabama, where the State Supreme Court ruled in Feb that #embryos were “unborn children.”
