Treat jellyfish stings with heat, not cold
When confronted with a jellyfish sting, people often reach for an ice pack for relief. But a new study out of the University of Hawaii has found that the opposite approach is more effective.
A recent study by researchers at UH MÄnoa, published this month in the journal Toxins, may finally put to rest the ongoing debate about whether to use cold or heat to treat jellyfish stings. Their systematic and critical review provides overwhelming evidence that clinical outcomes from all kinds of jellyfish stings are improved following treatment with hot packs or hot-water immersion.
Jellyfish stings are a growing public health concern worldwide and are responsible for more deaths than shark attacks each year.

April is Tsunami Awareness Month in Hawaii
Hawaii Emergency Management Agency (HI-EMA) is encouraging the public to take tsunami preparedness into their own hands this April during Tsunami Awareness Month. Seventy years ago, on April 1, 1946, one of the deadliest tsunamis to ever hit Hawaii caused widespread devastation on all islands. Generated by an earthquake in the Aleutian Islands, the massive tsunami took 159 lives and caused more than $26 million in damage. April was chosen as the month to honor and remember the lives lost in all tsunamis to hit the state.
Due to Hawaii’s location in the middle of the Pacific Ocean, we are extremely vulnerable to the threat of tsunamis. Distantly generated tsunamis can reach Hawaii within several hours and are triggered by earthquakes that take place along the Ring of Fire, which circles the Pacific Rim. Locally generated tsunamis are caused by earthquakes or volcanic activity that occur in or near the Hawaiian Islands, and can make landfall in a matter of minutes.

Solar Impulse Extends Hawaii Stay through April 2016
The solar powered airplane of Bertrand Piccard and André Borschberg will stay in Hawaii until early spring 2016, despite early efforts to repair the batteries which overheated in the record breaking oceanic flight from Nagoya to Hawaii.
Following the longest and most difficult leg of the round-the-world journey — which lasted five days and five nights (117 hours and 52 minutes) — Solar Impulse will undergo maintenance repairs on the batteries due to damages brought about by overheating.
“After checking what happened, we came to the conclusion that we preferred to change these batteries before going further in the flight around the world,” said Borschberg in a special interview with Bytemarks Cafe on Hawaii Public Radio that will air later today. “And it’s not so simple, it’s not like changing the batteries of a car, it’s a bit more complex, so it will take more time.”

Astronomers Discover Three Earth-Like Planets
Extrasolar planets are being discovered by the hundreds, but are any of these newfound worlds really like Earth? A planetary system recently discovered by the Kepler spacecraft will help resolve this question.
The system of three planets, each just larger than Earth, orbits a nearby star called EPIC 201367065. The three planets are 1.5-2 times the size of Earth, and the outermost planet orbits on the edge of the so-called “habitable zone,†where the temperature may be just right for liquid water, believed necessary to support life, on the planet’s surface.
“We’ve learned in the past year that planets the size and temperature of Earth are common in our Milky Way galaxy,†explains University of Hawaii astronomer Andrew Howard. “We also discovered some Earth-size planets that appear to be made of the same materials as our Earth, mostly rock and iron.â€

Latest crew set for 8-month simulated Mars mission
The six astronaut-like crew members of the next Hawai‘i Space Exploration Analog and Simulation (HI-SEAS) mission starting October 15 will be isolated in their dome habitat for eight months. This mission is twice as long as any previously completed at the Hawaiʻi site, and second only to Russia’s Mars500 experiment in total duration.
Also, for the first time, HI-SEAS will have a female commander. In NASA history, only two women have ever commanded the spaceship: astronauts Eileen Collins in July 1999, and Pamela Melroy in November 2007.
For true space flight, the commander role requires previous astronaut experience as well as at least 1,000 hours experience piloting a jet aircraft. For HI-SEAS, Commander Martha Lenio was selected based on feedback from fellow crew members and from instructors of the National Outdoor Leadership Skills course that both NASA and HI-SEAS require of their teams in training.

Microbes touted as key to future agriculture
A local technology commercialization company is working with two mainland biotechnology firms to encourage the adoption of microbial treatments to boost agricultural productivity while reducing water consumption as well as cutting the use of fertilizers and pesticides.
“Everything we’ve been taught about farming is incorrect,†declares Vincent Kimura, president of Inovi Green. “Historical and current agricultural processes of crop fertilization and soil tilling are falling out of favor, damaging ecosystems and producing diminishing returns. Environmentally-friendly microbial treatments have evolved to do this work far more effectively.â€

How do volcanoes affect the weather and climate?
Topography indisputably influences the weather—that’s why precipitation is so much greater on the windward side of the island. But how much did Hawai‘i’s topography influence Iselle? Hurricane Iselle weakened to a tropical storm just as it reached the island, but still managed to make landfall. As it did, the bulk of the storm stalled on the east flank of Mauna Loa, but its weakened upper parts continued moving westward.

Third historic volcano found off O‘ahu
University of Hawaii researchers, working with colleagues in California and France, have discovered evidence of a third major shield volcano making up the island of O‘ahu.
Previously, geologists believed the island’s current profile is the remnants of two volcanoes, Wai‘anae and Ko‘olau. But extending almost 100 km WNW from Ka‘ena Point, the western tip of the island of O‘ahu, is a large region of shallow bathymetry, called the submarine Ka‘ena Ridge. It is that region that has now been recognized to represent a precursor volcano to the island of O‘ahu, and on whose flanks the Wai‘anae and Ko‘olau Volcanoes later formed.
The team included scientists from the University of Hawai‘i–MÄnoa, Laboratoire des Sciences du Climat et de L’Environment in France, and Monterey Bay Aquarium Research Institute.

Deep origins to the behavior of our volcanoes
KÄ«lauea volcano, on the Big Island of Hawaii, typically has effusive eruptions, where magma flows to create ropy pÄhoehoe lava. But KÄ«lauea sometimes erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in KÄ«lauea’s eruption styles, a research team analyzed 25 eruptions that have taken place over the past 600 years.
Their research shows that the ultimate fate of a magma at Kīlauea — that is if the eruption will be effusive or explosive — is strongly influenced by the variability in composition of the deep magma. In short, more gas-rich magmas produces more explosive eruptions.
“Gas-rich magmas are ‘predisposed’ to rise quickly through the Earth’s mantle and crust and erupt powerfully,†Houghton explained.

Hawaii lab finds dramatic shift in Pacific ecosystem
The Hawaii Undersea Research Laboratory (HURL) has enabled scientists to determine that a long-term shift in nitrogen content in the Pacific Ocean has occurred as a result of climate change. Researchers observed overall nitrogen fixation in the North Pacific Ocean has increased by about 20 percent since the mid 1800s and this long-term change appears to be continuing today, according to a study published recently in the journal, Nature.
Using chemical information locked in organic skeletal layers, the team used these ancient deep corals as detailed recorders of changes at the base of the open Pacific food web over the last 1,000 years. This represents the first detailed biogeochemical records for the planet’s largest contiguous ecosystem. This type of sample is only available using deep-diving submersibles, such as those operated by HURL.
