Researchers discover surprising quantum effect in hard disk drive material

Posted by in categories: materials, quantum physics

Scientists find surprising way to affect information storage properties in metal alloy.

Sometimes scientific discoveries can be found along well-trodden paths. That proved the case for a cobalt-iron alloy material commonly found in .

As reported in a recent issue of Physical Review Letters, researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory, along with Oakland University in Michigan and Fudan University in China, have found a surprising quantum effect in this alloy.

Fast, efficient and durable artificial synapse developed

Posted by in category: robotics/AI

The brain’s capacity for simultaneously learning and memorizing large amounts of information while requiring little energy has inspired an entire field to pursue brain-like – or neuromorphic – computers. Researchers at Stanford University and Sandia National Laboratories previously developed one portion of such a computer: a device that acts as an artificial synapse, mimicking the way neurons communicate in the brain.

In a paper published online by the journal Science on April 25, the team reports that a prototype array of nine of these devices performed even better than expected in processing speed, , reproducibility and durability.

Looking forward, the want to combine their artificial synapse with traditional electronics, which they hope could be a step toward supporting artificially intelligent learning on small devices.

Northrop Grumman highlights benefits of Orbital ATK acquisition

Posted by in categories: business, innovation

WASHINGTON — Nearly a year after Northrop Grumman’s acquisition of Orbital ATK closed, company executives say they’re getting the benefits they expected from the deal in terms of cost savings and new business.

In a quarterly earnings report issued April 24, Northrop reported total sales of $8.19 billion and net earnings of $863 million for the first quarter of 2019. The company had total sales of $6.74 billion and net earnings of $840 million for the same quarter of 2018.

The increase in sales was due almost entirely to the addition of the Innovation Systems business unit, the former Orbital ATK. That unit generated $1.44 billion in sales for the quarter. In the first quarter of 2018, the last full quarter Orbital ATK was still an independent company, it reported sales of $1.31 billion.

Dark-matter detector observes exotic nuclear decay

Posted by in categories: cosmology, particle physics

From the point of view of nuclear theory, the decay rates of both two-neutrino and neutrinoless double electron capture can be connected to quantities called nuclear matrix elements. Such quantities contain information about nuclear structure that is extracted from nuclear models and can be applied by researchers in the field of nuclear-structure theory.


For half a century, our view of the world has been based on the standard model of particle physics. However, this view has been challenged by theories that can overcome some of the limitations of the standard model. These theories allow neutrinos to be Majorana particles (that is, they are indistinguishable from their own antiparticles) and predict the existence of weakly interacting massive particles (WIMPs) as the constituents of invisible ‘dark matter’ in the Universe. Majorana neutrinos mediate a type of nuclear decay called neutrinoless double-β decay, an example of which is neutrinoless double electron capture. A crucial step towards observing this decay is to detect its standard-model equivalent: two-neutrino double electron capture. In a paper in Nature, the XENON Collaboration reports the first direct observation of this process in xenon-124 nuclei, using a detector that was built to detect WIMPs.

World’s largest medical drone delivery network takes flight in Ghana

Posted by in categories: biotech/medical, drones

The largest drone delivery network in the world has been launched in Ghana, which experts say will save lives and transform the developing nation’s healthcare sector.

The drone network is set to deliver blood, essential medicines and vaccinations across the middle-income, West African country.

Speaking about the official launch of the service on April 24, Ghana’s President Nana Addo Dankwa Akufo-Addo said it was part of a drive to ensure universal access to lifesaving medicine in Ghana.
