Once cotton gets wet, it pulls heat from your body. This is helpful when you're exercising or outside on a hot day, but dangerous in the bitter cold. Now, researchers reporting in ACS Energy Letters have created an ultralight ...

Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...

Life on Earth has evolved under an uninterrupted rhythm of day and night. While light provides the energy that powers countless molecular processes, periods of darkness often allow biological systems to reorganize, recover ...

When living cells grow, divide or respond to drugs, they give off tiny amounts of heat that offer information about what the cells are doing. But because these heat signals are so vanishingly small, they have traditionally ...

Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously ...

AI data centers are power-hungry. Not only do artificial intelligence computations consume enormous amounts of electricity, but a significant amount of energy is also required to cool the semiconductor chips that heat up ...

What would it take to instantly transform a material from an electrical insulator into a conductive state without ever touching it? Using ultrafast laser pulses and powerful X-rays, scientists at the National Synchrotron ...

The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all modern electronic devices. This control is typically attained using a gate, an electrode via which ...

Pack enough string-like objects together, and they will begin to align with one another. But replace the strings with worms or bacteria living in your gut, and this self-organization becomes much more difficult. A team of ...

Quantum materials, materials with properties that are governed by the laws of quantum mechanics, have proved to be highly promising for the development of ultra-efficient electronic devices, quantum processors, highly precise ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside cells that had previously ...

Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and wave-like behaviors, ...
