School of tuna, for article on tuna recovery

Vast marine protected area in the Pacific Ocean has led to significant rebound in tuna stocks

Marine protected areas can do more than guard what’s inside their borders — and Papahānaumokuākea is proving it. This vast Hawaiian reserve, spanning over 580,000 square miles, was created to protect biodiversity and culturally sacred Indigenous sites, not to boost commercial fishing. Yet catch rates for yellowfin tuna in surrounding waters rose 54%, a spillover effect driven by the monument’s sheer scale. The findings strengthen the global case for ambitious ocean protection, arriving just as momentum builds toward safeguarding 30% of the world’s oceans by 2030.

Newborn baby being held, for article on spina bifida treatment

World-first stem cell therapy trial treats spina bifida before birth

Spina bifida causes nerve damage that accumulates in the womb, and until now, medicine could only respond after that damage was done. A clinical trial at UC Davis Health is changing that window, applying a stem cell patch directly to a fetus’s spine during pregnancy to support repair before birth. The first baby treated was expected to arrive with leg paralysis — instead, she was kicking and wiggling her toes. If results hold across all 35 enrolled patients, this could establish a genuinely new standard of care for a condition that currently offers families very little hope.
