A persistent obstacle to a more complete understanding of Earth's auroral activity is characterizing the structure of auroral arcs in 3D. In situ observations, such as spacecraft transits, can directly observe only a narrow ...

The tiny male golden orb-weaving spider faces a considerable challenge when searching for a mate. He is a fraction of the size of the massive female, but must carefully enter her web and approach her without being noticed, ...

Threads or earphone cables placed in tight spaces get easily tangled. On the contrary, our body's long and loose DNA packs into rod-shaped chromosomes one-millionth its size when the cell divides. If cell division occurs ...

The mid-ocean "twilight zone" holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult. Many inhabitants ...

The Standard Model of particle physics has been extremely successful in describing how the universe works. However, there are some things that it cannot explain. Physicists have, therefore, been looking for new physics in ...

One of the best chances for proving beyond-the-standard-model physics relies on something called the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The standard model insists that the CKM matrix, which describes the mixing of quarks, ...

Experiments have spotted anomalies hinting at a new type of neutrino, one that would go beyond the standard model of particle physics and perhaps open a portal to the dark sector. But no one has ever directly observed this ...

Visible matter, or the stuff that composes the things we see, is made of particles that can be thought of much like building blocks made of more building blocks, ever decreasing in size, down to the sub-atomic level. Atoms ...
