Fertility treatment raised stroke related risk by 44% but not other heart disease risks.

Fertility treatment did not raise most heart and kidney disease risks over 30 years. It did raise the risk of stroke related brain blood flow problems by 44%. Women who had trouble getting pregnant, whether they used fertility treatment or not, tended to have higher risks of heart and kidney problems in general.

The number 44% higher risk

The extra risk of stroke related brain blood flow problems after fertility treatment, over 30 years.

Swedish registry data, 1992 to 2002 births, limited precision for early years.

A baby's gut bacteria come mainly from its mother's gut, not birth or milk.

A mother's own gut bacteria are the main source of the bacteria in her baby's gut. This comes from a large study that tracked 714 mothers and babies, using 4,526 stool samples from early pregnancy to one year after birth. Breast milk and the birth canal only rarely passed bacteria to babies. How a baby was born and fed shaped its gut bacteria the most, and the mother's gut bacteria helped predict whether her baby got eczema.

The size of the study that tracked gut bacteria from pregnancy through a baby's first year.

One country, observational only, no proof of cause.

In lab-grown human fetal brain tissue, an immune signal sped up brain growth and caused early folding.

A lab-made 3D model of real human fetal brain tissue lets scientists study how infections during pregnancy affect brain growth. A signal called IL-17A, made by the immune system during infections, caused the tissue to fold too early. It also grew thicker and made brain cells too fast. This signal switched on a stress pathway inside brain stem cells, and a drug blocking that pathway reversed the changes.

What it could change A drug blocking an inflammation pathway reversed abnormal brain tissue growth caused by an immune signal.

Shows a possible cause and a possible fix, both tested only in lab tissue, not in pregnancy.

Lab-grown tissue only, no living pregnancies tested yet.

In climate models, fixing a rainfall error made simulated Pacific warming look more like the real ocean.

Real ocean data show something odd. The eastern Pacific Ocean has cooled while the western Pacific has warmed faster. Climate models do not show this pattern. They instead predict more even warming across the whole ocean. Models that make a smaller error, a fake extra band of storm clouds south of the equator, matched real ocean data better. This suggests human caused climate change may explain more of the odd Pacific pattern than scientists thought.

What it could change A common rainfall error in climate models hides the true cause of a strange Pacific Ocean warming pattern.

Models with a smaller storm cloud error better matched real ocean warming patterns.

Model based only, not observed proof, future forecasts may improve.

Monsoon winds carry ground pollution high into the sky, sparking new tiny particles there.

Every summer, monsoon winds over Asia carry dirty air high into the sky. This pollution helps form tiny new particles far above the ground. These particles grow large enough to affect clouds and sunlight. Winds then spread them across huge areas of the sky, both lower and higher up.

What it could change Ground pollution lofted by monsoon winds seeds new particles high in the sky.

Shows pollution's likely role in forming particles that can reach clouds and affect sunlight.

Field data plus models only, not a direct cause proof.
