Most people are familiar with the fact that sensitive instruments known as seismographs can detect earthquakes taking place many hundreds or thousands of miles away. By studying the waves from these tremors, scientists can find out about the conditions deep inside our rocky planet.
In the same way, astronomers are now able to measure millions of sound waves that propagate throughout the Sun, causing it to vibrate or ring like a bell. This technique, known as helioseismology, is the solar equivalent of terrestrial seismology.
On Monday 7 April, Dr. John Leibacher (U.S. National Solar Observatory) will highlight recent results from helioseismology studies during a presentation to the UK/Ireland Solar Physics Meeting in Dublin. These will include new views of the rapidly changing “sub-surface solar weather” and the far side of the Sun, as well as prospects for seeing finer and deeper details within the Sun and other stars.
“Unimaginable 25 years ago, helioseismology today allows us to ‘see’ into the otherwise invisible interior of the Sun,” said Dr. Leibacher. “This has enabled us to overthrow some theories, corroborate others, and pose many more new questions as we finally get a glimpse of how things work.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
