Hawaiʻi physicists help advance research into Earth’s radioactivity and nonproliferation

Antineutrino Global Map 2015

A team of researchers led by scientists at the National Geospatial-Intelligence Agency (NGA) published a new map on September 1 that characterizes the Earth’s radioactivity. The Antineutrino Global Map 2015 (AGM2015) can inform the strategic placement of detectors that aid in identifying undeclared nuclear reactors. The neutrino and its antimatter cousin, the antineutrino, are subatomic particles that are produced by ...

Hawaiʻi has been called the “extinction capital of the world.” But, with the exception of the islands’ birds, there has until now been no accurate assessment of the true level of this catastrophic loss. Invertebrates (insects, snails, spiders, etc.) constitute the vast majority of the species that make up Hawaiʻi’s formerly spectacularly diverse and unique biota. A team of researchers, ...

Bacteria affects sand more than seawater


Sewage-contaminated coastal waters can lead to stomach aches, diarrhea and rashes for those who accidentally swallow harmful microbes or come into contact with them. New research recently published in the American Chemical Society (ACS) journal Environmental Science and Technology sheds light on why fecal contamination affects sand more than water. University of Hawaiʻi at Mānoa Associate Professor of Civil and ...

Deep sea sharks are buoyant

Shark with tag

Scientists from the University of Hawaiʻi at Mānoa and University of Tokyo revealed that two species of deep-sea sharks, sixgill and prickly sharks, are positively buoyant—they have to work harder to swim downward than up and they can glide uphill for minutes at a time without using their tails. Their results were published in a recent study,“Unexpected Positive Buoyancy in ...
