Published DNA origami folded into tiny motor
(via sciencedaily.com) Original source Scientists have created a working nanoscale electomotor. The science team designed a turbine engineered from DNA that is powered by hydrodynamic flow inside a nanopore, a nanometer-sized hole in a membrane of solid-state silicon nitride. The tiny motor could help spark research into future applications such as building molecular factories or even medical probes of molecules inside the bloodstream.
Published Self-powered sensor automatically harvests magnetic energy
(via sciencedaily.com) Original source Researchers have designed a self-powering, battery-free, energy-harvesting sensor. Using the framework they developed, they produced a temperature sensor that can harvest and store the energy from the magnetic field that exists in the open air around a wire.
Published Study identifies new findings on implant positioning and stability during robotic-assisted knee revision surgery
(via sciencedaily.com) Original source An innovative study explores the use of robotic-assisted joint replacement in revision knee scenarios, comparing the pre- and post-revision implant positions in a series of revision total knee arthroplasties (TKA) using a state-of-the-art robotic arm system.
Published Higher measurement accuracy opens new window to the quantum world
(via sciencedaily.com) Original source A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).

(via sciencedaily.com) Original source A discovery from an experiment with magnetic materials and ultrafast lasers could be a boon to energy-efficient data storage.
Published New deepfake detector designed to be less biased
(via sciencedaily.com) Original source New algorithms close the gap in deepfake detectors' accuracy across races and genders.
Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
Published Advancement in thermoelectricity could light up the Internet of Things
(via sciencedaily.com) Original source Researchers have improved the efficiency of heat-to-electricity conversion in gallium arsenide semiconductor microstructures. By judicious spatial alignment of electrons within a two-dimensional electron gas system with multiple subbands, one can substantially enhance the power factor compared with previous iterations of analogous systems. This work is an important advance in modern thermoelectric technology and will benefit the global integration of the Internet of Things.
Published Physicists identify overlooked uncertainty in real-world experiments
(via sciencedaily.com) Original source The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, researchers argue that uncertainty in the thermodynamic parameters themselves -- built into equations that govern the energetic behavior of the system -- may also influence the outcome of an experiment.
