Tiny nanoparticles improve charge transport

Three-dimensional topological insulators are materials that can conduct electric current without resistance—but only on their surface. However, this effect is difficult to measure. This is because these materials usually ...

Vampire fish could be hitching rides from larger hosts

A team of researchers with Universidade Federal do Amazonas, Universidade Federal do Rio Grande and Washington and Lee University has found evidence of candiru (aka vampire fish) attaching themselves to hosts but not feeding ...

Provoking climate engagement

Most of us have become accustomed to hearing that global warming is one of the biggest challenges facing the world. At the same time, the topic can make us feel powerless, and it is easy to think that we can't do much about ...

Could low-altitude reconnection power Jupiter's polar aurorae?

Like Earth, Jupiter's magnetic field channels electrically charged particles into its atmosphere, resulting in the formation of brilliant aurorae near its poles. However, the brightness and variety of Jupiter's auroral emissions ...

Rising pension age will cut volunteering

Every year about 6 million Australian volunteers chip in more than 500 million hours of unpaid labor but raising the retirement age will reduce people's ability to contribute their free time and efforts, a Flinders University ...

Novel assay finds new mechanism underlying red blood cell aging

Red blood cells are the most abundant cell type in blood, carrying oxygen throughout the human body. In blood circulation, they repetitively encounter various levels of oxygen tension. Hypoxia, a low oxygen tension condition, ...

Earthly lava tubes may offer insights into extraterrestrial life

Since 1997, NASA has successfully landed five rovers on Mars. The rovers have beamed back data that indicate life cannot survive on the Martian surface; we do not know whether life persists below the ground, however. For ...
