Traditional methods of vacuum suction and previous vacuum suction devices cannot maintain suction on rough surfaces due to vacuum leakage, which leads to suction failure. Researchers have developed a zero-pressure difference method to enhance the development of vacuum suction units. Their method ove...

In 2017, a massive new region of magnetic field erupted on the sun's surface next to an existing sunspot. The powerful collision of magnetic energy produced a series of solar flares, causing turbulent space weather conditions at Earth. Scientists have now pinpointed for the first time exactly when a...

Using DNA, smallest silica particles, and carbon nanotubes, researchers developed novel programmable materials. These nanocomposites can be tailored to various applications and programmed to degrade quickly and gently. For medical applications, they can create environments in which human stem cells ...

The most distant dying galaxy discovered so far, more massive than our Milky Way -- with more than a trillion stars -- has revealed that the 'cores' of these systems had formed already 1.5 billion years after the Big Bang, about 1 billion years earlier than previous measurements revealed. The discov...

These microbes can have considerable impact on (animal) fertility and reproduction. They may even lead to ne...
