Researchers from Mass General Brigham and collaborating institutions have developed a non-invasive approach to manipulate cardiac tissue activity by using light to stimulate an innovative ink incorporated into bioprinted tissue...

Researchers at the Technical University of Darmstadt and the Helmholtz Center Dresden-Rossendorf have developed flexible robot wings that are moved by magnetic fields. Inspired by the efficiency and adaptability of the wings of the monarch butterfly, they enable precise movements without electronics or batteries.

This bio-inspired development could fundamentally change environmental monitoring, rescue operations and biomedical applications.

Monarch butterflies are known for their outstanding endurance and adaptability. Every year, they cover thousands of kilometers on their migrations between Canada and Mexico. The key to this feat lies in their unique wings, which allow the insects to fly energy-efficiently through a combination of active movement and passive bending.

These ...

The low levels of gravity (microgravity) in space cause significant changes in astronauts’ eyes and vision after six to 12 months aboard the International Space Station (ISS), according to a study published in the IEEE Open Journal of Engineering in Medicine and Biology.

Université de Montréal ophthalmologist Santiago Costantino found that at least 70% of astronauts on the ISS have been affected by spaceflight-associated neuro-ocular syndrome, or SANS.

In the biophotonics research unit he runs at the UdeM-affiliated Maisonneuve-Rosemont Hospital, Costantino assembled a group of researchers to identify the biomechanical changes responsible for this disorder.

They analyzed data collected by the Canadian team at NASA on 13 astronauts who spent between 157 and 186 days on the I...

Past research suggests that meditation and exposure to art or nature can positively impact people’s well-being and brain health, in some cases even reducing stress and supporting the processing of emotions. Yet most past studies focused on each of these experiences individually, rather than comparing their effects on brain activity.

Researchers at University of California Los Angeles set out to examine the brain activation patterns associated with a visualization-based transcendental meditation of connecting to the cosmic soul and compare them to those from people watching evocative digital art or nature videos.

Their findings, published in Frontiers in Human Neuroscience, suggest that these different types of transcending experiences prompt different brain activation patterns.
