Deaf moths evolved noise-cancelling scales to evade prey

Some species of deaf moths can absorb as much as 85 per cent of the incoming sound energy from predatory bats—who use echolocation to detect them. The findings, published in the Journal of the Royal Society Interface today, reveal the moths, who are unable to hear the ultrasonic calls of bats, have evolved this clever defensive strategy to help it survive.

These parasitic flatworms invade the snail's body and use its systems to support their colony, sometimes for over a decade, "driving them around like cars," according to senior author Ryan Hechinger, professor of marine sciences at Scripps Institution of Oceanography at the University of California San...

MicroRNA regulates process vital to placenta growth in early pregnancy

Researchers have discovered how a very large human non-protein coding gene regulates epithelial-to-mesenchymal transition (EMT) -- a process that contributes to placental implantation during early pregnancy, as well as cancer progression and spread. EMT plays a key role in proper placenta growth, critical to the health of the mother and her growing fetus. The USF Health team showed that robustly...

Instrument may enable mail-in testing to detect heavy metals in water

Researchers have developed an approach called SEPSTAT, for solid-phase extraction, preservation, storage, transportation, and analysis of trace contaminants. The method is based on a small, user-friendly device the team developed, which absorbs trace contaminants in water and preserves them in a dry state so the samples can be easily dropped in the mail and shipped to a laboratory for further...
