Mutant clownfish reveals how nature draws boundaries

A plant uses a rare scent to guide its pollinator to male flowers first and to female flowers later, finds a study led by Kobe University. The work, appearing in Current Biology, uncovers a precise chemical system that not only keeps this partnership specific but also helps ensure it remains beneficial to both parties.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new "hot Jupiter" exoplanet. The newfound alien world, designated TOI-7169 b, orbits a metal-poor star, which is rare among exoplanets. The finding was detailed in a paper published March 26 on the arXiv pre-print server.

When people are talking, they can start to unconsciously mirror each other, for instance, in the words they use, their sentence structures and even hand gestures. This tendency to mirror others can lead to smoother conversations, while also fostering empathy and collaboration.

The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make up our power grid, and up and down to light up every floor of every building. But the electrons in newly discovered "moiré crystals" move in much stranger ways. They can move left and right, back and forth, or up and down in our three-dimensional world, but these electrons also act as if they can teleport in and out of a mysterious fourth dimens
