Bronze warship ram reveals secrets
(Phys.org) —Analysis of a bronze battering ram from a 2000 year-old warship sheds light on how such an object would have been made in ancient times.
Researchers measure cavitation noise in trees
Air bubbles could be the secret to artificial skin
(Phys.org) —Using foam substrates, EPFL scientists were able to make a flexible electronic circuit board. This discovery could lead to the creation of deformable and stretchable circuits.
I'm forever imploding bubbles
The National Physical Laboratory (NPL) has developed the first sensor capable of measuring localized ultrasonic cavitation - the implosion of bubbles in a liquid when a high frequency sound wave is applied. The sensor will ...
Cassini completes Rhea flyby
(PhysOrg.com) -- NASA's Cassini spacecraft has successfully completed its closest flyby of Saturn's moon Rhea, returning raw images of the icy moon's surface.
Findings indicate the edge of the solar system is filled with a turbulent sea of magnetic bubbles
Boston University astronomer Merav Opher will feature prominently in a NASA teleconference this week to discuss the latest findings about the nature of the solar system.
Sediment trapped behind dams makes them 'hot spots' for greenhouse gas emissions
With the "green" reputation of large hydroelectric dams already in question, scientists are reporting that millions of smaller dams on rivers around the world make an important contribution to the greenhouse ...
Clot-dissolving bubbles to treat strokes?
(Medical Xpress)—Researchers are using computer simulations to investigate how ultrasound and tiny bubbles injected into the bloodstream might break up blood clots, limiting the damage caused by a stroke ...
Getting to know the sun advances fusion research
Researchers at the Princeton Plasma Physics Laboratory have successfully used Coaxial Helicity Injection (CHI) to generate plasma current and couple it to a conventional current generation method at the National Spherical ...
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'.
Measuring the Speed of Noble 'Bubbles'
(PhysOrg.com) -- Using a layer of noble gas "bubbles," scientists at Pacific Northwest National Laboratory devised a straightforward way to measure how fast molecules diffuse in supercooled liquids. Working ...
Zoning restrictions also a key factor in foreclosure crisis, scholar says
The causes of the foreclosure crisis seem obvious: Buyers purchased homes they couldn't afford, lured in part by lenders pushing subprime mortgages. Real estate values escalated, and when the bubble burst, ...
Underwater gas may hold clues on Turkey quake risk
Natural gas that lies under Turkey's Marmara Sea close to Istanbul could provide advance warning of an earthquake experts believe will hit the country's largest city, scientists said on Tuesday.
