What happens when a large meteor crashes into the Earth? The impact of a large meteorite releases an enormous amount of energy that evaporates, melts and fractures areas surrounding the impact over distances that can range over hundreds of kilometers. Although the subject of abundant recent interest, little is directly known about the propagation of damage during these events.
Three researchers from the Hebrew University of Jerusalem have come up with a new picture of damage propagation, which explains the distinctive rock deformations generated by the high-energy shockwaves produced in these extreme conditions. These results provide new insight into meteor impact dynamics as well as dissipative mechanisms in materials subjected to sudden, extremely intense fluxes of energy. Using these results, analysis of deformed rock structures surrounding the site of an intense explosion or impact can provide a quantitative measure of its strength – even if the event occurred a billion years ago.
These findings will be published in the prestigious scientific journal Nature on Thursday, July 18, in the article, “Dynamic Fracture by Large Extraterrestrial Impacts as the Origin of Shatter Cones,” by Ph.D. candidate Amir Sagy, Physics Prof. Jay Fineberg and Geology Prof. Ze’ev Reches.

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...
