Tientallen vrouwen hebben in een bewustwordingscampagne verteld hoe zij werden getroffen door placenta accreta spectrum. • Vrouwen moesten een grote spoedoperatie ondergaan, waaronder een hysterectomie, nadat medisch personeel er niet in slaagde vast te stellen dat zij een zeldzame maar potentieel fatale zwangerschapscomplicatie hadden. • Tientallen vrouwen hebben hun verhaal gedeeld over hoe zij werden getroffen door placenta accreta spectrum (PAS), sinds de lancering in februari van een campagne om NHS-personeel en aanstaande moeders bewust te maken van de risico's die dit met zich meebrengt.

Over the next two weeks stargazers have a chance to spot the blue-green orb and smudgy tail of comet known as C/2025 R3 PanSTARRS A comet formed on the edges of the solar system will grace southern skies over the next fortnight, giving viewers a rare chance to glimpse it before it disappears from view for another 170,000 years.The comet – known as C/2025 R3 PanSTARRS – had been travelling through the northern hemisphere but has “swung around the sun” and is now visible in the south, said Josh Aoraki, an astronomer at Te Whatu Stardome in Auckland, New Zealand.

• Northland analysts have initiated a buy rating on USA Rare Earth as the U.S. pursues rare earth independence from China. • The move reflects broader geopolitical efforts to establish domestic supply chains for critical materials essential to technology and defense sectors. • Rare earth elements are vital for electronics, renewable energy, and military applications, making supply chain security a strategic priority.

Researchers find increase in whale deaths in the Bay, largely because of collisions with vessels on busy shipping routeGray whales have historically been a rare sight in the San Francisco Bay. They trek from the warm lagoons of Mexico’s Baja California over 10,000 miles north to the Arctic region to feast on shrimp-like animals during the summers, seldom stopping in the busy shipping corridor for prolonged periods.But in recent years, that story has changed in a dire way. A new study, published this week in the journal Frontiers in Marine Science, has found that gray whales in the Bay have been dying at alarming rates, largely due to collisions with vessels.

• Researchers at the Facility for Rare Isotope Beams (FRIB) directly measured the proton capture reaction of arsenic-73 forming selenium-74, the lightest p-nucleus, using a rare isotope beam. • Led by Artemis Tsantiri, the study involved over 45 scientists from 20 U.S., Canadian, and European institutions, published in Physical Review Letters. • This first-of-its-kind experiment sharpens models of p-nuclei formation, proton-rich heavy isotopes that have puzzled astronomers.
