Scientists achieve collective quantum behavior in macroscopic oscillators

Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the quantum realm, macroscopic oscillators could enable ultra-sensitive sensors and components for quantum computing, opening new possibilities for innovation in various industries.

Controlling mechanical oscillators at the quantum level is essential for developing future technologies in and ultra-precise sensing. But controlling them collectively is challenging, as it requires near-perfect units, i.e., identical.

Most research in quantum optomechanics has centered on single oscillators, demonstrating like ground-state cooling and quantum squeezing. But this hasn’t been the case for collective quantum behavior, where many oscillators act as one. Although these collective dynamics are key to creating more powerful quantum systems, they demand exceptionally over multiple oscillators with nearly identical properties.

Charge your phone in your pocket with new wireless technology

A groundbreaking advancement in technology is paving the way for mobile phones and other electronic devices to recharge simply by being kept in a pocket. This innovative system enables wireless charging throughout three-dimensional (3D) spaces, encompassing walls, floors, and air.

On December 12, Professor Franklin Bien and his research team in the Department of Electrical Engineering at UNIST announced the creation of a revolutionary electric resonance-based (ERWPT) system, marking a significant milestone in the field. This modern technology allows devices to charge virtually anywhere within a 3D environment, addressing the longstanding challenges associated with traditional magnetic resonance wireless power transfer (MRWPT) and offering a robust solution that enables efficient power transmission without the constraints of precise device positioning.

The paper is published in the journal Advanced Science.

BadBox malware botnet infects 192,000 Android devices despite disruption

The BadBox Android malware botnet has grown to over 192,000 infected devices worldwide despite a recent sinkhole operation that attempted to disrupt the operation in Germany.

Researchers from BitSight warn that the malware appears to have expanded its targeting scope beyond no-name Chinese Android devices, now infecting more well-known and trusted brands like Yandex TVs and Hisense smartphones.

Innovative Device could Power Electronics using Body Movements

A new technology that can generate electricity from vibrations or even small body movements means you could charge your laptop by typing or power your smartphone’s battery on your morning run.

Researchers at the University of Waterloo have developed a tiny, wearable generator in response to the urgent need for sustainable, clean energy. It is also scalable for larger machines. Their paper, “Breaking Dielectric Dilemma: Polymer Functionalized Perovskite Piezocomposite with Large Current Density Output,” is published in the November edition of Nature Communications.

“This is a real game changer,” said Dr. Asif Khan, the project’s lead researcher and a postdoctoral fellow in the Department of Electrical and Computer Engineering at Waterloo. “We have made the first device of its kind that can power electronics at low cost and with unprecedented efficiency.”

Adobe announces development of SLM that can Run Locally on a Phone with No Cloud Connection

A small team of AI researchers at Adobe Inc., working with a colleague from Auburn University and another from Georgia Tech, has developed a small language model (SLM) that they claim can be run locally on a smart phone with no access to the cloud. The group has written a paper describing their new app, which they call SlimLM, and have posted it to the arXiv preprint server.

As LLM technology continues to mature, researchers across the globe continue to find new ways to improve it. In this new effort, the research team has found a way to cut the cord for a specific type of AI application—processing documents locally.

As LLMs such as ChatGPT become more popular, users have become more worried about privacy. And it is not just individuals—companies large and small have adopted AI applications that assist with a variety of business processes, some of which require a high degree of privacy.

Spain busts voice phishing ring for defrauding 10,000 bank customers

The Spanish police, working with colleagues in Peru, conducted a simultaneous crackdown on a large-scale voice phishing (vishing) scam ring in the two countries, arresting 83 individuals.

Thirty-five of the arrested people were located across Spain, including in Madrid, Barcelona, Mallorca, Salamanca, and Vigo, and another 48 were arrested in Peru.

The leader of the ring was also apprehended in Spain during the 29 simultaneous raids conducted by the cooperating police forces, which also seized cash, mobile phones, computers, and documents.

TidyBot++: An Open-Source Holonomic Mobile Manipulator for Robot Learning

Exploiting the promise of recent advances in imitation learning for mobile manipulation will require the collection of large numbers of human-guided demonstrations. This paper proposes an open-source design for an inexpensive, robust, and flexible mobile manipulator that can support arbitrary arms, enabling a wide range of real-world household mobile manipulation tasks. Crucially, our design uses powered casters to enable the mobile base to be fully holonomic, able to control all planar degrees of freedom independently and simultaneously. This feature makes the base more maneuverable and simplifies many mobile manipulation tasks, eliminating the kinematic constraints that create complex and time-consuming motions in nonholonomic bases. We equip our robot with an intuitive mobile phone teleoperation interface to enable easy data acquisition for imitation learning.

This Programmer Ran an Augmented Reality Game on a 2007 Nokia Phone

For those unaware, Whisk3D (original name Blendersito) is Dante’s Symbian-powered version of Blender, which he has been developing since late 2022. The app allows users to upload and model 3D characters on the phone, design game level assets, extrude vertices and edges, create planes, and even connect the phone to a monitor and keyboard for more convenient use.

In a true Blender fashion, Dante’s Whisk3D is open-source and can be accessed via the creator’s GitHub page. You can also support Dante here and check out more jaw-dropping experiments with Nokia-ran Blender over here.

Rethinking the brain pacemaker: How better nanocomposites can improve signals

Two years ago, a medical professional approached scientists at the University of Tabriz in Iran with an interesting problem: Patients were having headaches after pacemaker implants. Working together to investigate, they began to wonder if the underlying issue is the materials used in the pacemakers.

“Managing that affects patients is crucial,” author Baraa Chasib Mezher said. “For example, a person with a may experience interference from external electrical fields from phones or the sounds of cars, as well as various electromagnetic forces present in daily life. It is essential to develop novel biomaterials for the outlet gate of brain pacemakers that can effectively handle .”

In an article published this week in AIP Advances, Mezher, who is an Iraqi doctoral student studying in Iran, and her colleagues at the Nanostructured and Novel Materials Laboratory at the University of Tabriz created organic materials for brain and heart pacemakers, which rely on uninterrupted signal delivery to be effective.
