Some volcanoes 'scream' at ever-higher pitches until they blow their tops
It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made ...
Champion nano-rust for producing solar hydrogen
EPFL and Technion researchers have figured out the "champion" nanostructures able to produce hydrogen in the most environmentally friendly and cheap manner, by simply using daylight.
Microbes found in natural asphalt lake
Babbling brooks adding to climate change?
(Phys.org) —Studying stream bubbles isn't exactly a walk in the park. What, with the mud and ticks, the long days hiking and swimming through mucky streams, the sun exposure and scratching brush.
Clues to foam formation could help find oil
Blowing bubbles in the backyard is one thing and quite another when searching for oil. That distinction is at the root of new research by Rice University scientists who describe in greater detail than ever ...
Voyager 1 magnetic data surprise intrigues researchers
(Phys.org) —A University of Alabama in Huntsville graduate student and a recent UAH doctoral graduate are exploring surprising data from Voyager 1's crossing of the heliopause into the interstellar medium ...
Bubble mattress reduces drag in fluidic chip
Researchers at the University of Twente's MESA+ research institute have given the first demonstration of how the drag exerted on liquids flowing through tiny "fluidic chips" is affected by the introduction of diminutive gas ...
In prehistory, CO2 and warming went in lock-step
Levels of carbon dioxide rose hand-in-hand with warming at the end of the last Ice Age, according to a study Thursday that deals a blow to climate skeptics.
The birth of a very-high-field superconductor
The strong magnetic fields of an MRI scanner or a particle accelerator are generated efficiently by electromagnets that have superconducting wire in their coils. A group of scientists has discovered how to ...
Illuminating the no-man's land of waters' surface
Sylvie Roke, scientist in EPFL's Bioengineering Institute, is refuting previously held theories and offering a new explanation of electrochemical phenomena occurring at the interface between water and a hydrophobic ...
Nano insights could lead to improved nuclear reactors: Researchers examine self-healing abilities of some materials
(Phys.org)—In order to build the next generation of nuclear reactors, materials scientists are trying to unlock the secrets of certain materials that are radiation-damage tolerant. Now researchers at the ...
Russia 'drills into' Antarctic subglacial lake
A Russian team has succeeded in drilling through four kilometres (2.5 miles) of ice to the surface of a mythical subglacial Antarctic lake which could hold as yet unknown life forms, reports said Monday.
Stranded dolphins exhibit bubbles, and ability to recover
Scientists know that the blood and tissues of some deceased beaked whales stranded near naval sonar exercises are riddled with bubbles. It is also well know that human divers can suffer from bubbles-induced ...
Scientists move closer to predicting volcano hazard
UK and Russian scientists say they are a step closer to predicting how dangerous a volcano is after developing a method that lets them figure out how individual volcanoes are 'plumbed'.
