Breakthrough in nanoscale force measurement opens doors to unprecedented biological insights

Posted by in categories: biotech/medical, nanotechnology

Groundbreaking research has revealed a new way to measure incredibly minute forces at the nanoscale in water, pushing the boundaries of what scientists know about the microscopic world.

The significant nanotechnology advance was achieved by researchers from Beihang University in China with RMIT University and other leading institutions including the Australian National University and University of Technology Sydney (Nature Photonics, “Sub-femtonewton force sensing in solution by super-resolved photonic force microscopy”).

The new technique, involving a super-resolved photonic force microscope (SRPFM), is capable of detecting forces in water as small as 108.2 attonewtons – a scale so minute that it compares to measuring the weight of a virus.

Scientists discover new behavior of membranes that could lead to unprecedented separations

Posted by in categories: biotech/medical, chemistry, food

Imagine a close basketball game that comes down to the final shot. The probability of the ball going through the hoop might be fairly low, but it would dramatically increase if the player were afforded the opportunity to shoot it over and over.

A similar idea is at play in the scientific field of membrane separations, a key process central to industries that include everything from biotechnology to petrochemicals to water treatment to food and beverage.

“Separations lie at the heart of so many of the products we use in our everyday lives,” said Seth Darling, head of the Advanced Materials for Energy Water Systems (AMEWS) Center at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. “Membranes are the key to achieving efficient separations.”

Diving Into 3 Key DARPA AI Programs

Posted by in categories: military, robotics/AI

As one of the Department of Defense’s 14 critical technology areas, artificial intelligence has taken center stage in the organization’s research and development endeavors.

According to Matt Turek, deputy director of the Defense Advanced Research Projects Agency’s Information Innovation Office, approximately 70 percent of the agency’s programs now use AI and machine learning. Its priorities are not just to develop systems for U.S. warfighters, but to prevent “strategic surprise” from adversary AI systems.

Quantum computing breakthrough solves key obstacle for revolutionary tech

Posted by in categories: computing, quantum physics

In the race to develop practical quantum computers, a team of researchers has achieved a significant milestone by demonstrating a new method for manipulating quantum information. This breakthrough, published in the journal Nature Communications, could lead to faster and more efficient quantum computing by harnessing the power of customizable “nonlinearities” in superconducting circuits.

Quantum computers promise to revolutionize computing by leveraging the principles of quantum mechanics to perform complex calculations that are impossible for classical computers. However, one of the main challenges in building quantum computers is the difficulty in manipulating and controlling quantum information, known as qubits.

The researchers, led by Axel M. Eriksson and Simone Gasparinetti from Chalmers University of Technology in Sweden, have developed a novel approach that allows for greater control over qubits by using a special type of superconducting circuit called a SNAIL (Superconducting Nonlinear Asymmetric Inductive eLement) resonator.

Hard Yet Stretchable: Scientists Create “Unbreakable” New Material

Posted by in categories: biotech/medical, materials

Researchers have created a new class of materials called “glassy gels” that are as hard as glassy polymers, but – if you apply enough force – can stretch up to five times their original length, rather than breaking. A key thing that distinguishes glassy gels is that they are more than 50% liquid, which makes them more efficient conductors of electricity than common plastics that have comparable physical characteristics.

Researchers have developed a new class of materials known as glassy gels, which combine the hardness of glassy polymers with the stretchability of gels.

Post-silicon nano-electronic device and its application in brain-inspired chips

Posted by in categories: information science, nanotechnology, robotics/AI

As information technology is moving toward the era of big data, the traditional Von-Neumann architecture shows limitations in performance. The field of computing has already struggled with the latency and bandwidth required to access memory (“the memory wall”) and energy dissipation (“the power wall”). These challenging issues, such as “the memory bottleneck,” call for significant research investments to develop a new architecture for the next generation of computing systems. Brain-inspired computing is a new computing architecture providing a method of high energy efficiency and high real-time performance for artificial intelligence computing. Brain-inspired neural network system is based on neuron and synapse. The memristive device has been proposed as an artificial synapse for creating neuromorphic computer applications. In this study, post-silicon nano-electronic device and its application in brain-inspired chips are surveyed. First, we introduce the development of neural networks and review the current typical brain-inspired chips, including brain-inspired chips dominated by analog circuit and brain-inspired chips of the full-digital circuit, leading to the design of brain-inspired chips based on post-silicon nano-electronic device. Then, through the analysis of N kinds of post-silicon nano-electronic devices, the research progress of constructing brain-inspired chips using post-silicon nano-electronic device is expounded. Lastly, the future of building brain-inspired chips based on post-silicon nano-electronic device has been prospected.

Keywords: brain-inspired chips; neuron; phase change memory; post-silicon nano-electronic device; resistive memory; synapse.

Technological Singularity: AI and Post-Human Era

Posted by in categories: Ray Kurzweil, robotics/AI, singularity

Technological singularity: a hypothetical event where artificial intelligence (AI) surpasses human capabilities and leads to a transformative cascade of change.

Technological singularity: a hypothetical event where artificial intelligence (AI), pushed by exponential growth in computational power and intelligence, surpasses human capabilities and leads to a transformative cascade of change.

Coined by mathematician John von Neumann and popularized by futurist Ray Kurzweil, the singularity signifies a critical moment in human history—one where the trajectory of civilization takes an unpredictable turn and the boundaries between humans and machines blur. Kurzweil argued that technological progress follows an exponential trajectory and predicted that the singularity would occur around the year 2045, leading to a merging of human and machine intelligence and unprecedented levels of innovation.

Warp drives could generate gravitational waves

Will future humans use warp drives to explore the cosmos? We’re in no position to eliminate the possibility. But if our distant descendants ever do, it won’t involve dilithium crystals, and Scottish accents will have evaporated into history by then.
