Researchers have found that ongoing thyroid hormone imbalance in pregnancy may be linked to higher autism risk in children. Treated thyroid disorders did not show the same effect. The longer the imbalance lasted across trimesters, the more the risk appeared to rise. The study underscores the need for consistent thyroid monitoring.

A decade-long study of older women found that tea drinkers had slightly stronger bones, while moderate coffee drinking caused no harm. Heavy coffee intake—over five cups a day—was linked to lower bone density, especially in women who consumed more alcohol. Tea’s benefits may stem from catechins that support bone formation. The researchers say small daily habits could make a meaningful difference over time.
Tea may strengthen bones in older women while heavy coffee weakens them

Worrying about getting older—especially fearing future health problems—may actually speed up aging at the cellular level, according to new research from NYU. In a study of more than 700 women, those who felt more anxious about aging showed signs of faster biological aging in their blood, measured using cutting-edge “epigenetic clocks.” Fears about declining health had the strongest link, while concerns about beauty or fertility didn’t appear to have the same biological impact.

Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells. By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells that help maintain brain health. In mice that already showed memory problems, this approach reduced plaque buildup and preserved cognitive function over time.

Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s activity was blocked. The findings help explain how hormonal cycles influence cognitive performance and psychiatric symptoms. This connection offers a new path for understanding brain disorders tied to dopamine.

A long-term Australian study found that calcium supplements do not raise dementia risk in older women, countering previous fears. The research followed more than 1,400 participants for nearly 15 years and revealed no harmful cognitive effects. Scientists say these results should reassure those using calcium to prevent osteoporosis, though more research is needed across broader populations.

Women who undergo C-sections are more likely to experience debilitating pain and sleep disorders in the months after giving birth. Researchers found both qualitative and large-scale data supporting this link, including a 16% increase in sleep disorder diagnoses. Proper pain management and healthy sleep habits can reduce these risks, helping new mothers recover more smoothly and avoid complications like depression and fatigue.

Menopause brings profound shifts not just in hormones but in the very structure of the brain. Scientists have found that gray matter in regions tied to memory and thinking can shrink, while white matter may show damage linked to blood flow issues. Yet there’s hope — evidence points to partial recovery and adaptive changes postmenopause.

An international team of researchers led by scientists from the Max Planck Institute for Evolutionary Anthropology in Leipzig, working with 15 collaborators around the world, has conducted the most comprehensive study yet of lifespan differences between the sexes in mammals and birds. Their findings shed new light on one of biology’s enduring mysteries: why males and females age differently.
