Precession sufficient to generate a magnetic field. Flows of molten metal can generate magnetic fields. This dynamo effect creates cosmic magnetic fields, like those found on planets, moons and even asteroids. Over the coming years, a globally unique experiment, in which a steel drum containing several tons of liquid sodium rotates around two axes, is intended to demonstrate this effect. It will be carried out in the new DRESDYN facility at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an independent German research laboratory.

Similarly to how a bicycle dynamo converts motion into electricity, moving conductive fluids can generate magnetic field...

Hollow pumpkin-shaped molecules with allyloxy tails self-assemble into vesicles which can carry drugs into cancer cells. Then a laser breaks the vesicles which facilitates the release of the drug in a timely and location-specific manner. Credit: IBS

Light-responsive vesicles carry and release drugs to cancer cells at specific time and position. With the goal of minimizing the side effects of chemotherapy on healthy tissues, scientists have developed novel nanocontainers able to deliver anticancer drugs at precise timing and location. They combines uniquely designed molecules and light-dependent drug release, which may provide a new platform to enhance the effect of anticancer therapeutics.

Thanks to a serendipitous observation, IBS researchers at POSTECH found out that tailed pumpkin-shape...

New kinds of ‘superlattices’ could lead to improvements in electronics, from transistors to LEDs. A research team led by UCLA scientists and engineers has developed a method to make new kinds of artificial “superlattices” – materials composed of alternating layers of ultra-thin “2D” sheets, which are only one or a few atoms thick...

Using data from three different satellites, scientists have developed new models that recreate, in 3-D, CMEs and shocks, separately. Credit: Image courtesy of NASA/Goddard Space Flight Center

Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the Sun – an effort made possible only by combining data from three NASA satellites to produce a much more robust mapping of a CME than any one could do alone. CMEs set off interplanetary shocks when they erupt from the Sun at extreme speeds, propelling a wave of high-energy particles. These particles can spark space weather events around Earth, endangering spacecraft and astronauts...
