Advanced Light Source evidence confirms combustion theory

soot formation

Researchers at UH Mānoa have published the first direct experimental evidence for the validity of a fundamental reaction mechanism thought to play a key role in the astrochemical evolution.  The so-called HACA mechanism–the hydrogen abstraction-acetylene addition mechanism–had so far only been speculated theoretically.  A news highlight from the Advanced Light Source user facility at the Lawrence Berkeley National Laboratory describes the research ...

U.N. task force says new ocean telecom cables should be ‘green’

global undersea communications cable infrastructure

The global system of submarine telecommunications cables that supports our connected world is deaf, dumb and blind to the external ocean environment – and represents a major missed opportunity for tsunami warning and global climate monitoring, according to UH scientists and a United Nations task force. “For an additional 5-10 percent of the total cost of any new cable system ...

Massive debris pile reveals risk of huge tsunamis in Hawaii

1946 Hawaii tsunami

A mass of marine debris discovered in a giant sinkhole provides evidence that at least one mammoth tsunami, larger than any in Hawaiʻi’s recorded history, has struck the islands, and that a similar disaster could happen again, new research finds.  Scientists, led by Rhett Butler, Director of the Hawai‘i Institute of Geophysics and Planetology (HIGP) at UH Mānoa, are reporting ...

BOFFFFs [Big, Old, Fat, Fertile, Female Fish] sustain fisheries

Big Fish

Recreational fishermen prize large trophy fish.  Commercial fishing gear targets big fish.  After all, larger fish feed people’s egos as well as their bellies. A new compilation of research from around the world now shows that big, old, fat, fertile, female fish – known as BOFFFFs to scientists – are essential for ensuring that fishery stocks remain sustainable. “Information on ...

Hunting monsters…with sound

Infrasound data

UH Mānoa’s Milton Garces has contributed a new essay to the Sounding Out blog’s “Hearing the Unheard” series.  The story highlights Garces’ research work in infrasound, low-frequency sounds in the atmosphere that are inaudible to the human ear, but can carry for thousands of kilometers.  Infrasound has a variety of important and practical applications including its use in detecting secret missile ...

New study shows the importance of jellyfish to deep-sea ecosystem

Jellyfish baits in the deep sea

This week, researchers from University of Hawai‘i, Norway, and the UK have shown with innovative experiments that a rise in jellyfish blooms near the ocean’s surface may lead to jellyfish falls that are rapidly consumed by voracious deep-sea scavengers.Previous anecdotal studies suggested that deep-sea animals might avoid dead jellyfish, causing dead jellyfish from blooms to accumulate and undergo slow degradation ...
