Researchers John S. Wettlaufer and J. G. Dash propose an alternative explanation for the behavior of a solid isotope of helium at low temperatures. They suggest that a thin, lubricating superfluid film forms between the solid and its container due to melting at the boundary, which occurs in all solids.
Plant cells use programmed cell death to protect against viruses, but this process must be controlled to avoid killing the plant. Researchers found that silencing a specific gene, BECLIN-1, helps regulate PCD and prevent infection from spreading.

High concentrations of BPA have been reported in pregnant women's blood, potentially impacting human hippocampal development and long-term effects on children's learning ability.
Researchers discovered that low levels of protein Z and S early in pregnancy can increase the risk of pregnancy complications. The study included 103 women with normal pregnancies, 106 with pregnancy complications, and 20 with inherited clotting conditions. Women with prior complications may be at higher risk for future issues.
