Buckling on Command

Posted by in categories: computing, nanotechnology

An electromechanical device allows researchers to control and study how a nanoscale beam buckles when compressed.

The buckling of a column or other structural element is typically something that engineers want to avoid, but a new device offers a way to control this type of deformation on microscopic scales. The design combines small actuators and circuits that generate mechanical and electrostatic forces on a nanoscale beam, causing it to buckle to the left or to the right. By manipulating the beam’s deformation, researchers may be able to harness buckling for sensitive detectors or for testing the relationship between thermodynamics and computing.

Facing a Downpour of Data, Scientists Look to the Cloud

Posted by in categories: computing, physics

To improve access to large data sets, scientists are looking to cloud-based solutions for data management.

In the coming decade, big projects like the Large Hadron Collider (LHC) and the Square Kilometre Array (SKA) are each expected to produce an exabyte of data yearly, which is about 20 times the digital content of all the written works throughout human history. This information overload requires new thinking about data management, which is why scientists have begun to look to the “cloud.” In such a scenario, data would be stored and analyzed remotely, with the advantage that information would become more accessible to a wider scientific community. Efforts are underway to create “science clouds,” but disagreements remain over their structure and implementation. To discuss these details, around 60 scientists came together for The Science Cloud meeting in Bad Honnef, Germany. The attendees shared lessons from past and ongoing projects in the hope of building the groundwork for a future scientific computing infrastructure.

How to Escape the Confines of Time and Space According to the CIA

Posted by in categories: computing, neuroscience

In the ’80s, the spy agency investigated the “Gateway Experience” technique to alter consciousness and ultimately escape spacetime. Here is everything you need to know.


She turned to me the other morning and said, “You heard of The Gateway?” It didn’t register in the moment. She continued, “It’s blowing up on TikTok.” Later on, she elaborated: It was not in fact the ill-fated ’90s computer hardware company folks were freaking out about. No, they’ve gone further back in time, to find a true treasure of functional media.

The intrigue revolves around a classified 1983 CIA report on a technique called the Gateway Experience, which is a training system designed to focus brainwave output to alter consciousness and ultimately escape the restrictions of time and space. The CIA was interested in all sorts of psychic research at the time, including the theory and applications of remote viewing, which is when someone views real events with only the power of their mind. The documents have since been declassified and are available to view.

Scientists Finally Solve the 40-Year-Old Mystery of Strange Metals

Posted by in categories: computing, quantum physics

For nearly 40 years, materials called ‘strange metals’ have flummoxed quantum physicists, defying explanation by operating outside the normal rules of electricity.

Now research led by Aavishkar Patel of the Flatiron Institute’s Center for Computational Quantum Physics (CCQ) in New York City has identified, at long last, a mechanism that explains the characteristic properties of strange metals.

In the August 18 issue of Science, Patel and his colleagues present their universal theory of why strange metals are so weird—a solution to one of the greatest unsolved problems in condensed matter physics.

Quantum computing is the next revolution

Posted by in categories: computing, quantum physics

Dr. Michio Kaku, the renowned theoretical physicist, walks us through the evolutionary journey of computing, from analog to digital to the quantum era.

Quantum computers hold immense promise because of their ability to tap into the weirdness of quantum mechanics. If nature allows us full access to its secrets, we could boost computing power exponentially, which in turn would allow us to solve all types of complex problems.

10-fold Speed up For The Reconstruction of Neuronal Networks

Posted by in categories: computing, mapping, neuroscience

Scientists working in connectomics, a research field occupied with the reconstruction of neuronal networks in the brain, are aiming at completely mapping of the millions or billions of neurons found in mammalian brains. In spite of impressive advances in electron microscopy, the key bottleneck for connectomics is the amount of human labor required for the data analysis. Researchers at the Max Planck Institute for Brain Research in Frankfurt, Germany, have now developed reconstruction software that allows researchers to fly through the brain tissue at unprecedented speed. Together with the startup company scalable minds they created webKnossos, which turns researchers into brain pilots, gaining an about 10-fold speedup for data analysis in connectomics.

Billions of nerve cells are working in parallel inside our brains in order to achieve behaviours as impressive as hypothesizing, predicting, detecting, thinking. These neurons form a highly complex network, in which each nerve cell communicates with about one thousand others. Signals are sent along ultrathin cables, called axons, which are sent from each neuron to its about one thousand “followers.”

Bigger and better quantum computers possible with new ion trap, dubbed the Enchilada

Posted by in categories: computing, economics, engineering, nuclear energy, quantum physics, security

Another concern was the dissipation of electrical power on the Enchilada Trap, which could generate significant heat, leading to increased outgassing from surfaces, a higher risk of electrical breakdown and elevated levels of electrical field noise. To address this issue, production specialists designed new microscopic features to reduce the capacitance of certain electrodes.

“Our team is always looking ahead,” said Sandia’s Zach Meinelt, the lead integrator on the project. “We collaborate with scientists and engineers to learn about the kind of technology, features and performance improvements they will need in the coming years. We then design and fabricate traps to meet those requirements and constantly seek ways to further improve.”

Sandia National Laboratories is a multimission laboratory operated by National Technology and Engineering Solutions of Sandia LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration. Sandia Labs has major research and development responsibilities in nuclear deterrence, global security, defense, energy technologies and economic competitiveness, with main facilities in Albuquerque, New Mexico, and Livermore, California.
