Phys.org / Microrobots in swarms for medical embolization
Microrobotic agents can form swarms of targeted drug delivery for improved imaging analyses. In a new report now published in Science Advances, Junhui Law and a team of researchers in mechanical and industrial engineering, ...
Phys.org / The central core clock machinery drives the majority of metabolic rhythms
Life on earth is based on recurring 24-hour environmental cycles that are genetically encoded as molecular clocks active in all mammalian organs. Communication between these clocks can control circadian homeostasis. Temporal ...
Phys.org / A unique stone-skipping-like trajectory of asteroid Aletai
During their entry to Earth, meteoroids and asteroids can deposit energy, causing great concerns to astrophysicists. Recent discoveries of the massive Aletai irons in Northwest China constitute the longest-known strewn field, ...
Tech Xplore / Providing embedded artificial intelligence with a capacity for palimpsest memory storage
Biological synapses are known to store multiple memories on top of each other at different time scales, much like representations of the early techniques of manuscript writing known as "palimpsest," where annotations can ...
Phys.org / Universal optothermal micro/nanoscale rotors
The fundamental rotation of micro and nano-objects is crucial for the functionality of micro and nanorobotics, as well as three-dimensional imaging and lab-on-a-chip systems. These optical rotation methods can function fuel-free ...
Phys.org / Microporous polymer membranes for light-gated ion transport
In a new report now published in Science Advances, Zongyao Zhou and a team of scientists in chemical engineering and physical science and engineering at the King Abdullah University of Science and Technology in Saudi Arabia ...
Medical Xpress / A reference tissue atlas for the human kidney
A team of researchers including Jens Hansen, Rachel Sealfon, Rajastree Menon, and colleagues of the Kidney Precision Medicine Project, built on an existing specific human kidney tissue atlas relevant to health care at single-cell ...
Phys.org / Upcycling plastics through dynamic cross-linking
If bioengineers can upcycle commodity plastics into higher-performance materials, they can establish sustained closed-loop manufacturing with broader industrial and environmental benefits. For example, upcycled plastics can ...
Phys.org / Expanding RNA interference (RNAi) therapeutics from the lab to the clinic
It is now possible to deliver therapeutics based on short interfering RNAs to hepatocytes; however, new delivery solutions are necessary to target additional organs. In a new report now published in Nature Biotechnology, ...
Tech Xplore / Geometrically engineered rigid island array for stretchable electronics
Stretchable electronics can be developed by integrating rigid components in a soft polymer matrix. However, it is challenging to eliminate cracks at the interface between soft and rigid materials. In a new report now published ...
Phys.org / The physicochemical nature of colloidal motion waves among silver colloids
Traveling waves are commonly observed in biological and synthetic systems, and recent discoveries have shown how silver colloids form traveling motion waves in hydrogen peroxide under UV light. In a new report now published ...
Medical Xpress / A soft wearable stethoscope designed for automated remote disease diagnosis
Digital stethoscopes provide better results compared to conventional methods to record and visualize modern auscultation. Current stethoscopes are bulky, non-conformal, and not suited for remote use, while motion artifacts ...
Phys.org / Topologically tuned terahertz on a nonlinear photonic chip
Compact terahertz functional devices are highly useful for high-speed wireless communication, biochemical sensing and non-destructive inspection. However, controlled terahertz generation, alongside transport and detection ...
Phys.org / Microfluidics-assisted synthesis of stimuli-responsive chitosan microgels for drug delivery applications
Droplet microfluidics provide a robust platform to synthesize and functionalize micro- and nanoparticles in a range of applications, including drug delivery, screening, lab-on-a-chip and organ-on-a-chip applications, across ...
Phys.org / Coherent oscillation between phonons and magnons
Two different waves with the same frequency and wavelengths can be coupled, so that the amplitude alternates periodically between the two to form a phenomenon known as a coherent beating oscillation. The process can be observed ...
