New research has found that two types of weevils, common yet invasive beetles in many parts of the world, have been using epigenetic changes to adapt and respond to different toxins in the plants they eat. The findings have implications for how we consider asexual invaders and how successful they can be because of gene regulation.
Astronomers have developed a new way to capture all the exquisite 'layer-cake' details of a brown dwarf's cloud structure. Because brown dwarfs are similar to super-Jupiters, this innovative technique can help deepen scientists' understanding of the atmospheres of giant alien worlds that are more massive than Jupiter.
Areas with climatic conditions suitable for sustaining permafrost in the Daisetsu Mountains are projected. The size of the area in the Daisetsu Mountains where climatic conditions were suitable for permafrost were estimated to be approximately 150 km2 in 2010. Under the business-as-usual scenario, this area is projected to disappear by around 2070. Under the low-carbon scenario consistent with Paris target scenario, the area is projected to decrease to approximately 13% of 2010 by 2100.
Researchers have shown that a targeted therapy using non-thermal radio waves is safe to use in the treatment of hepatocellular carcinoma (HCC), the most common type of liver cancer, according to a new study. The therapy also showed a benefit in overall survival.
In the biomaterials industry, electrospinning is a ubiquitous fabrication method used to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture. Alas, the process has traditionally used solvents that not only are environmentally hazardous but also a significant barrier to industrial scale-up, clinical translation, and widespread use. But now, researchers report that they have developed a 'green electrospinning' process that addresses those challenges, from managing environmental risks of volatile solvent storage and disposal at large volumes to meeting health and safety standards during both fabrication and implementation.
