New Ultrasound Method could lead to Easier Disease Diagnosis

University of Sheffield researchers have developed a new ultrasound method that could help to more easily diagnose abnormal tissue, scarring and cancer. A new ultrasound method that can measure the level of tension in human tissue for the first time – a key indicator of disease – has been developed by researchers from the University of Sheffield.

The breakthrough, made by Dr Artur Gower from the University’s Department of Mechanical Engineering, together with researchers from Harvard, Tsinghua University, and the University of Galway, could be used to build new ultrasound machines that are able to better diagnose abnormal tissue, scarring, and cancer.

Ultrasounds use sound waves to create images of organs inside the human body...

Scientists Transform Algae into Unique Functional Perovskites with Tunable Properties

Calcitic shells of the dinoflagellate L. granifera. A) The calcitic shells of L. granifera exhibiting a porous ultrastructure. B) A single shell of L. granifera. C) Raman spectrum from a single shell confirming its calcitic nature. D) Electron back-scattering diffraction (EBSD) map and E) a corresponding (0001) pole figure of a single polished shell demonstrating that it consists of single crystalline domains where the c-axis of calcite is pointing radially from the center of the shell outwards. The colors in (E) correlate with similarly colored areas in (D). Scale bars: (A) 50 Âµm, (B) 5 Âµm and (D) is 5 Âµm.

Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties...

What are the hydrocarbon seas on Titan really like? While the upcoming Dragonfly helicopter mission to Saturn’s hazy and frigid moon should arrive by 2034 to explore Titan’s atmosphere, the need remains for a mission that could study the moon’s mysterious seas and lakes, filled with liquid hydrocarbons.

But how about an aircraft that could study both the seas and skies of Titan?

A new mission concept that received funding from NASA’s Innovative Advanced Concepts (NIAC) Program is called “TitanAir,” and features a flying boat, known as a laker...

Healthy Gut Bacteria can help Fight Cancer in other parts of the body, researchers find

Healthy gut bacteria can help fight cancer in other parts of the body, researchers find
Immune checkpoint therapy (ICT) helps gut microbiota travel from the gut to the lymph nodes where they activate immune cells (dendritic cells and T cells). Ultimately, both gut microbiota and activated immune cells then enter the tumor. When specific bacteria cannot travel to the lymph node and tumor and activate immune cells, immune checkpoint therapy is not effective. Credit: Science Immunology (2023).

Researchers at UT Southwestern Medical Center have discovered how healthy bacteria can escape the intestine, travel to lymph nodes and cancerous tumors elsewhere in the body, and boost the effectiveness of certain immunotherapy drugs...
