Kīlauea volcano, on the Big Island of Hawai'i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island.

A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring, according to a new paper published in Proceedings of the Royal Society B.
Climate change is set to affect the quality of the wines of the Tempranillo grape variety, according to the conclusions of a piece of research conducted by the Basque Institute for Agricultural Research and Development Neiker-Tecnalia, in collaboration with the University of Navarre and the Aula Dei (EEAD) Experimental Station of the National Council for Scientific Research (CSIC). Scientists from these bodies have studied the behaviour of the vines in conditions of climate change; in other words, higher temperature, increased presence of CO2 and greater environmental aridity.
SAN FRANCISCO -- The oldest sections of transform faults, such as the North Anatolian Fault Zone (NAFZ) and the San Andreas Fault, produce the largest earthquakes, putting important limits on the potential seismic hazard for less mature parts of fault zones, according to a new study to be presented today at the Seismological Society of America (SSA) 2014 Annual Meeting in Anchorage, Alaska. The finding suggests that maximum earthquake magnitude scales with the maturity of the fault.
Carbon-based nanostructures such as nanotubes, graphene sheets, and nanoribbons are unique building blocks showing versatile nanomechanical and nanoelectronic properties. These materials which are ordered in the nanoscale, that is, in the dimension of a millionth of millimetre, are promising candidates to envision applications in nanoscale devices, ranging from energy conversion to nano-electronic transistors.
The weather system that dropped tornadoes in seven central and southern U.S. states on April 27-28, moved east and generated more tornadoes on April 29. NASA's Aqua satellite gathered temperature data on the thunderstorm cloud tops in the system and found them to be higher in the atmosphere and colder. The tornado outbreak over the evening and overnight hours of April 28-29 is thought to have generated more tornadoes in northern Mississippi and Alabama.
WASHINGTON, April 28, 2014 — Game of Thrones gave us a shock with the Purple Wedding and now everyone is asking: "Who poisoned King Joffrey?" While the search for the killer continues, the American Chemical Society's latest Reactions video focuses on what killed the hated king. The video is available at http://youtu.be/6UNEpRXcxM4
WASHINGTON D.C., April 29, 2014 -- Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics with the first rigorous formulation supporting the uncertainty principle as Heisenberg envisioned it.
A new physics discovery made by a University of Virginia-led team may lead to more efficient refrigerators, heat pumps and airport scanners, among many possible uses –perhaps within a decade.
The team of physicists and materials scientists have discovered a universal law governing the magnetic properties of metamagnets – metal alloys that can undergo dramatic increases in magnetization when a small external magnetic field is applied, such as from a permanent magnet or an electromagnet.
There is no disputing graphene is strong. But new research by Rice University and the Georgia Institute of Technology should prompt manufacturers to look a little deeper as they consider the miracle material for applications.
FORT LAUDERDALE-DAVIE, Fla. – It seems that coral reefs are experiencing something their human counterparts have been for years – a shrinking "empty nest" syndrome.
That's right – researchers have found that increasing ocean temperatures due to climate change will soon see reefs retaining and nurturing more of their own coral larvae, leaving large reef systems less interconnected.
Researchers have found that increasing ocean temperatures due to climate change will soon see reefs retaining and nurturing more of their own coral larvae, leaving large reef systems less interconnected and potentially more vulnerable.
"We found that at higher temperatures more coral larvae will tend to stay on their birth reef," says the lead author of the study published today, Dr Joana Figueiredo from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University.

NOAA's GOES-East satellite sits in a fixed orbit in space capturing visible and infrared imagery of weather over the eastern U.S. and Atlantic Ocean. The GOES-East satellite is operated by the National Oceanic and Atmospheric Administration. NASA/NOAA's GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md. created the animation of GOES-East satellite data that covered the period during the tornado outbreak.
