DASH-style diet associated with reduced risk of depression

Researchers found that participants who closely adhered to a DASH-style diet were less likely to develop depression than those who did not. The study, funded by the National Institutes of Aging, evaluated 964 participants and showed an association between a healthier diet and lower rates of depression.

Mom's immune system shapes baby's brain

A study published in JNeurosci found that a woman's immune system during pregnancy influences the development of her child's brain network, which may be linked to psychiatric disorders such as autism and schizophrenia. Higher maternal immune activation was also associated with improved cognitive ability in infants.

New research could lead to improved method of treating pancreatic cancer

Researchers at Binghamton University have developed a new method of treating pancreatic cancer using dual thermal ablation, which combines heating and freezing to kill cancer cells. The study found that this approach achieves complete cell death in pancreatic cancer cells more effectively than heating or freezing alone.

Mechanism of diamond formation

Researchers discovered diamond formation from ankerite through spontaneous iron reduction, suggesting a possible mechanism for abundant diamond creation in Earth's lower mantle. The process occurs without melting at high pressures and temperatures, similar to those found in meteoritic impact zones.
