Study: At-risk mothers receive less support, information on breastfeeding

A new study found that single mothers, those with less education, and mothers enrolled in the WIC Program may receive fewer resources and information to help them breastfeed. Despite receiving support from professionals, demographic differences and stress levels may affect their ability to engage in breastfeeding practices.

Meditation: An effective new therapy to reduce eye pressure in primary open-angle glaucoma

A new study published in the Journal of Glaucoma found that mindful meditation practice significantly lowers intraocular pressure, reducing stress-related biomarkers and improving quality-of-life. Meditation also positively influences other indicators, such as reduced cortisol levels and increased brain-derived neurotrophic factors.

What can a tau mouse model reveal about the effects of repetitive brain injury?

Researchers have developed a mouse model expressing human tau protein to study the effects of repetitive brain injury on cognitive function, motor dysfunction and white matter damage. The study found that repetitive concussive injuries resulted in chronic disruptions in white matter and associated neuroinflammation.

Is there a universal hierarchy of human senses?

A study conducted by researchers at the University of York found that cultures' emphasis on specific sensory experiences, such as music or pottery, affects their ability to communicate about different senses. This challenges the long-held assumption of a universal hierarchy of human senses.

Oldest evidence of dairying on the East Asian Steppe

Researchers discovered dairy pastoralism in Mongolia as early as 1300 BC through cultural transmission rather than population replacement or migration. Milk proteins were found in tooth tartar and dental calculus of ancient Mongolians, indicating the livestock were cattle, sheep, and goats introduced by Western Steppe herders.

Changing temperatures are helping corn production in US -- for now

A new study by Harvard researchers found that warmer temperatures and localized cooling have contributed to increased maize production in the US. A longer growing season and reduced exposure to high temperatures have boosted yields, with over a quarter of the increase attributed to these factors.

Cell transplant restores vision in rats

Researchers at the University of California, Irvine, have successfully restored vision in rats with severe retinal degeneration through cell transplantation. The study demonstrates that donor cells can integrate into the retina and generate nearly normal visual activity in the brains of blind animals.
