Owl Wing Design With Serrated Edges Reduces Aircraft, Wind Turbine Noise Pollution

Owl Wing Design With Serrated Edges Reduces Aircraft, Wind Turbine Noise Pollution

Good News Notes: “Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise pollution is a major environmental goal for some urban areas. In Physics of Fluids, by AIP Publishing, researchers from Xi’an Jiaotong University used the characteristics of owl wings to inform airfoil design and…

Using Sound Waves to Remotely Target Drugs to Tumors

Using Sound Waves to Remotely Target Drugs to Tumors

The lack of a clinically viable method to track and direct cancer drugs to tumors is a big problem for targeted therapeutics.

But a new ultrasonic method proposed by biomedical engineers from Qifa Zhou’s team at the University of Southern California in Los Angeles could enable acoustic control and real-time tracking of drug release within the body. The researchers report on their manipulation…

Structured Light Promises Path to Faster, More Secure Communications

Structured Light Promises Path to Faster, More Secure Communications

Structured light is a fancy way to describe patterns or pictures of light, but deservedly so as it promises future communications that will be both faster and more secure.

Quantum mechanics has come a long way during the past 100 years but still has a long way to go. In AVS Quantum Science, from AIP Publishing, researchers from the University of Witwatersrand in South Africa review the…

3D Printing, Bioinks Create Implantable Blood Vessels

3D Printing, Bioinks Create Implantable Blood Vessels

A biomimetic blood vessel was fabricated using a modified 3D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result is a fully functional blood vessel with a dual-layer architecture that outperforms existing engineered tissue and brings 3D-printed blood vessels several fundamental steps closer…

Squid-Inspired Robots Might Have Environmental, Propulsion Applications

Squid-Inspired Robots Might Have Environmental, Propulsion Applications

Inspired by the unique and efficient swimming strategy of cephalopods, scientists developed an aquatic robot that mimics their form of propulsion.

These high-speed, squidlike robots are made of smart materials, which make them hard to detect — an advantage that has potential military reconnaissance and scientific applications — while maintaining a low environmental footprint.

Physicists…

Simulations Characterize Turbulence Caused by Common Connection for Dialysis

Simulations Characterize Turbulence Caused by Common Connection for Dialysis

Patients with kidney failure often require arteriovenous grafts to be connected to dialysis machines for their lifesaving treatment. However, one common problem with the artificial tubes is they can induce dangerous blood clotting.

The complex interplay among the AVGs, the vessels they connect, and the blood they transport has been difficult to simulate with computers. One new method provides…

Using High Energy Density Material in Electrode Design Enhances Lithium Sulfur Batteries

Using High Energy Density Material in Electrode Design Enhances Lithium Sulfur Batteries

Lithium ion batteries aren’t keeping up with energy demands from higher power electronic devices, electric vehicles and smart electric grids. To develop higher capacity batteries, researchers have looked to lithium sulfur batteries because of sulfur’s high theoretical capacity and energy density.

But there are still several problems to solve before lithium sulfur batteries can be put into…

Predicting Epileptic Seizures Might Be More Difficult Than Previously Thought

Predicting Epileptic Seizures Might Be More Difficult Than Previously Thought

By studying the brain dynamics of 28 subjects with epilepsy, scientists demonstrated there is no evidence for a previously suspected warning sign for seizures known as “critical slowing down.”

In 2013, some of the first seizure-prediction devices were developed and successfully tested. Although extensive research efforts have successfully identified predictors of imminent seizures, the concept…
