Researchers have demonstrated that cold plasma can penetrate deep into tissue to effectively target and destroy tumor cells, even in deeper layers, by using new tissue models to understand the role of reactive molecules, potentially improving cancer treatments.
Researchers have discovered the mechanism that activates tardigrades' survival mode, known as the "tun state," when they encounter extreme conditions, which involves the oxidation of cysteines in response to reactive oxygen species. This finding could have implications for developing materials that can withstand harsh environments, as well as potential applications in cancer therapies. The research sheds light on how these microscopic creatures can survive in extreme environments, and the discovery may lead to innovations in various fields, from space exploration to medical treatments.
Scientists at Gladstone Institutes used CRISPR to identify molecules responsible for energy production and reactive oxygen species (ROS) in mitochondria, aiming to decouple energy from ROS production to develop therapies for neurodegenerative diseases. Their findings could lead to new treatment approaches for conditions like heart disease, diabetes, and cancer, as well as implications for healthy aging. The team plans to further research the impact of altered ROS levels on cellular health and validate their results in other cell types.
A recent study using a deep-sea chemiluminescent sensor called SOLARIS has revealed that deep-sea corals and sponges produce reactive oxygen species (ROS), specifically superoxide. This discovery suggests that these chemicals have previously unknown effects on ocean life and chemistry in the deep sea. The study also found that the production of superoxide is not solely a stress response but a fundamental part of the corals' regular life functions. The findings have implications for understanding coral health and activity, as well as how coral ecosystems may respond to climate change.
