Preeclampsia in pregnancy reduces risk of some cancers but raises endometrial cancer odds

Women with preeclampsia in their first pregnancy had a lower risk of developing breast, cervical, and lung cancer later in life, but a higher risk of endometrial cancer. The large Nordic cohort study also found that siblings of women with PE had a modestly reduced risk of cancer, particularly lung cancer.

EU researchers call for wider use of alternatives to animal testing

Researchers examine how the use of animal testing to identify endocrine-disrupting substances in the EU can be reduced. Although it is, in principle, possible to identify such substances without using animals, non-animal methods are still rarely applied.

Spaceflight exposes astronauts to hidden threats in their gut

This review highlights how the unique stressors of space travel, radiation, microgravity, and circadian disruption impact astronauts’ gut microbiomes, with potential consequences for their mood, cognition, and immunity. The authors call for targeted microbiome monitoring and dietary interventions to protect astronaut mental health on future missions.

Embryos from women with PCOS carry distinctive epigenetic memory

Novel research presented today at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) has found that embryos from women with polycystic ovary syndrome (PCOS) carry a distinctive 'epigenetic memory' that could explain why the condition often runs in families.
