Mountains!
Life on Earth is amazingly diverse, and exhibits striking geographical global patterns in biodiversity. A pair of companion papers reveal that mountain regions -- especially those in the tropics -- are hotspots of extraordinary and baffling richness. Although mountain regions cover only 25% of Earth's land area, they are home to more than 85% of…

Self-reference. Beauty.
When something pleases us visually - whether it's a fine piece of artwork, a beautiful feat of architecture, or an untouched natural landscape - new research demonstrates there is a pattern of activity in what's known as the default mode network (DMN). The DMN is a large-scale system of interacting regions in the brain that…

Organoids. Brain waves. Death…
Some years ago, two hundred and fifty miles over Alysson Muotri’s head, a thousand tiny spheres of brain cells were sailing through space. The clusters, called brain organoids, had been grown a few weeks earlier in the biologist’s lab here at the University of California, San Diego. He and his colleagues altered human skin cells…

Touching the untouched.
Jellyfish are about 95% water, which makes them very difficult to study because most of the underwater tools available to marine biologists are clunky, heavy, and often shred jellyfish and other delicate creatures to pieces. A new ultra-soft gripper uses fettuccini-like 'fingers' inflated with water to gently grasp jellyfish and release them without harm, allowing…

Quantum… time? Quantum… cosmos?!
An international group of physicists led by Stevens Institute of Technology, University of Vienna and University of Queensland reveal the quantum properties of time, whereby the flow of time doesn't observe a straight arrow forward, but one where cause and effect can co-exist both in the forward and backward direction. To show this scenario, researchers…
