Study Pinpoints Arctic Shorebird Decline

Red-neckedphalarope_ZakPohlen.jpg

A new study co-authored by WCS (Wildlife Conservation Society) addresses concerns over the many Arctic shorebird populations in precipitous decline. Evident from the study is that monitoring and protection of habitat where the birds breed, winter, and stopover is critical to their survival and to that of a global migration spectacle.

Underwater Sniffing of Star-Nosed Moles Is Mimicked for Chemical-Detecting ‘Electronic Nose’

Lee1.jpg

The star-nosed mole has several unusual abilities. One of them is “sniffing” underwater by blowing bubbles and quickly re-inhaling them, detecting odors of its prey through the water. The moles’ “star” nose features a ring of tiny, pink tentacles and is the most sensitive known touch organ of any mammal. Researchers will present their work exploring the star-nosed moles’ unusual underwater sniffing ability during the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

Stinging Cells Pack a Powerful Pressure

The stinging cells of jellyfish, called nematocytes, have evolved to be one of the world’s most efficient predation tools. The nematocysts consist of a capsule and folded tubule, and use high pressure and acceleration for defense and locomotion and, more importantly, to capture prey. Inconsistencies in a previous conceptual explanation of the stinging cell mechanism were identified using a microfluidic system and mathematical models. Researchers will share their mathematical model of nemotocytes at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017. The model demonstrates how environmental modifications can reduce the impact of jellyfish stinging capacity.

When to Fish: Timing Matters for Fish That Migrate to Reproduce

ASP_Day3-1054.jpg

A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.

Research Predicts Coral Adaptation is Possible if Ocean Warming Rates are Reduced

A new study led by researchers from UC Davis, UCLA, Stanford University and California State University, Monterey Bay (CSUMB) predicts coral adaptation is possible if ocean warming rates are reduced.

X-Rays Reveal the Biting Truth About Parrotfish Teeth

A new study has revealed a chain mail-like woven microstructure that gives parrotfish teeth their remarkable ability to chomp on coral all day long – the structure could serve as a blueprint for designing ultra-durable synthetic materials.

Closing the Rural Health Gap: Media Update from RWJF and Partners on Rural Health Disparities

nrhd-logo2017.png

Rural counties continue to rank lowest among counties across the U.S., in terms of health outcomes. A group of national organizations including the Robert Wood Johnson Foundation and the National 4-H Council are leading the way to close the rural health gap.
