UMass Amherst nanoparticle vaccine prevents cancers in mice
Researchers at the University of Massachusetts Amherst have developed a nanoparticle-based cancer vaccine that prevented melanoma, pancreatic, and triple-negative breast cancers in mice. Up to 88% of vaccinated mice remained tumor-free, with the vaccine also stopping metastasis. The approach uses a 'super adjuvant' to trigger strong immune responses.
Researchers develop electricity-generating device from air humidity
Iniulat ng AI
Scientists at the University of Massachusetts Amherst have created a small device that produces electricity by drawing on moisture in the air. This innovation, known as the Air-gen, operates continuously without sunlight or wind. The breakthrough could pave the way for sustainable power sources in various environments.
Scientists develop LED therapy to kill cancer cells safely
Researchers from the University of Texas at Austin and the University of Porto have created a cancer treatment using LED light and tin nanoflakes that destroys up to 92% of skin cancer cells without harming healthy tissue. This affordable alternative to traditional therapies relies on near-infrared photothermal principles. The breakthrough, published in ACS Nano, aims to make targeted cancer care more accessible worldwide.
Scientists make germanium superconducting for the first time
Researchers have achieved superconductivity in germanium, a common semiconductor, by precisely doping it with gallium atoms. This breakthrough, detailed in a new study, could enable more efficient quantum devices and cryogenic electronics. The material conducts electricity with zero resistance at 3.5 Kelvin.
MIT uncovers hidden atomic patterns in metals
