Astronomers have put NASA’s Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient “relic galaxy” in our own cosmic backyard. The very rare and odd assemblage of stars has remained essentially unchanged for the past 10 billion years. This wayward stellar island provides valuable new insights into the origin and evolution of galaxies billions of years ago...

A precession driven flow is supposed to power magnetic field self-excitation in a planned liquid metal dynamo experiment at HZDR. Credit: HZDR

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...
