Astrobiologists, who search for evidence of life on other planets, may find a proposed Neutron/Gamma ray Geologic Tomography (NUGGET) instrument to be one of the most useful tools in their toolbelt.
As conceived by scientists at the Goddard Space Flight Center (GSFC) in Greenbelt, Md., NUGGET would be able to generate three-dimensional images of fossils embedded in an outcrop of rock or beneath the soil of Mars or another planet. Tomography uses radiation or sound waves to look inside objects. NUGGET could help determine if primitive forms of life took root on Mars when the planet was awash in water eons ago.
Similar to seismic tomography used by the oil industry to locate oil reserves beneath Earth’s surface, NUGGET would look instead for evidence of primitive algae and bacteria that fossilized along the edges of extinct rivers or oceans. As on Earth, these remains could lie just a few centimeters beneath the surface, compressed between layers of silt. If a mechanical rover that explores planet surfaces were equipped with an instrument like NUGGET — capable of peering beneath the surface — then it might be able to reveal evidence of life beyond Earth.

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...
