Not your grandfather's house, but maybe it should be

Experts are looking into alternative materials that can be used in building houses, focusing on local sources such as bamboo and straw bales, while also considering economic and environmental factors. Khanjan Mehta emphasizes the importance of scalability and finding suitable alternatives for cement, which is often scarce and expensive.

Doping powers new thermoelectric material

Researchers at Northwestern University have developed a new thermoelectric material that converts waste heat to electricity more efficiently than previous materials. By doping tin selenide with sodium, they increased the material's performance, enabling it to produce significantly more electricity from the same amount of heat input.

Two case reports of rare stiff person syndrome

Two women with rare stiff person syndrome (SPS) have been successfully treated, one through auto-HSCT and the other through work and activity resumption. Both patients experienced significant symptom improvement, with the first patient no longer experiencing SPS symptoms after a year and the second able to return to work.

Probing dopant distribution

Researchers have demonstrated that the distribution of dopants in semiconductor nanocrystals is crucial for controlling optical properties. By probing electron distribution using x-ray photoelectron spectroscopy, they found that surface-doped samples exhibit reduced activation of dopants and symmetric plasmon resonances.
