A research team at the University of Boston’s Photonics Center developed an imaging tool that could replace the traditional form of MRI scan and ensure more accurate results and less anxiety.

Usually, patients undergoing such a medical procedure could experience stress and discomfort, however, the new helmet-like tool, which marks a revolution in the field of medical imaging, is characterized with a funny look that alleviates stress. During the study published Feb. 12 in the scientific journal Advanced Material, the researchers reported the metamaterial used in the design, packing in a ton of physics, engineering, and mathematical know-how. The design was overseen by Xin Zhang, professor of mechanical engineering at BU's Photonics Center.

“The metamaterials used in the helmet is a type of engineered structure created from small unit cells that might be unspectacular alone, but when grouped together in a precise way, get new superpowers not found in nature. Metamaterials, for instance, can bend, absorb, or manipulate waves -- such as electromagnetic waves, sound waves, or radio waves. Each unit cell is typically arranged in a repeating pattern in rows and columns; they can be designed in different sizes and shapes, and placed at different orientations, depending on which waves they're designed to influence,” explained Zhang.

The materials used in the helmet include a component that blocks sound without stopping airflow (imagine quieter jet engines and air conditioners) and a magnetic metamaterial that can improve the quality of magnetic resonance imaging (MRI) machines used for medical diagnosis. These materials were deployed in a helmet-like device, which fits over a person's head and can be worn during a brain scan, boosts MRI performance, creating crisper images that can be captured at twice the normal speed. According to Zhang, the helmet makes MRIs less costly and more time efficient for doctors, radiologists, and patients -- all while improving image quality, which will help make the technology more widely available, particularly in the developing countries.

SHAMS Engages Community with New Coral Initiative for Red Sea Protection

The General Organization for the Conservation of Coral Reefs and Turtles in the Red Sea (SHAMS) is set to launch a new environmental initiative titled “Adopt a Coral” this Saturday. The initiative aims to involve community members in the restoration of coral reefs and raise awareness of the importance of their sustainability as part of national efforts to protect the Kingdom’s marine environment.

This initiative aligns with SHAMS’ goals of enhancing community partnership and increasing public involvement in marine conservation. It also supports Saudi Vision 2030’s sustainability objectives and complements national programs such as the Saudi Green Initiative, which aims to reduce ecosystem degradation and preserve biodiversity, SPA reported.

SHAMS emphasized that the initiative is the result of years of field experience in coral reef restoration. The organization has demonstrated its capabilities in accurately identifying degraded reef areas using scientific indicators, developing innovative restoration techniques, and implementing long-term monitoring programs to assess ecological recovery.

The “Adopt a Coral” initiative offers various opportunities for public participation, including hands-on involvement in coral planting following specialized field training, attending awareness workshops and events that highlight threats to coral reefs such as climate change and marine pollution.

These opportunities empower the diving community to engage in reef monitoring and environmental advocacy, and foster a shared sense of responsibility by enabling individuals and groups to “adopt” coral as a symbol of ongoing environmental commitment.

The first phase of the initiative will be carried out at a designated coral reef site along the Red Sea coast, with participation from volunteers, divers, and environmental enthusiasts. SHAMS plans to expand the initiative in future phases to ensure long-term ecological impact and sustainable community engagement.

Coral reefs in the Red Sea are a vital artery for marine ecosystems, a rich source of biodiversity, and a key driver of economic and eco-tourism activity. In response to growing environmental challenges, the initiative emerges as a forward-thinking model of community engagement in the restoration of sensitive ecosystems. Through this program, SHAMS seeks to redefine environmental protection by directly connecting the public with the stewardship of this valuable natural resource.
