(Phys.org)—Researchers have created a self-powered electronic watch that harvests energy from the wearer's wrist movements for continuous operation. By combining two different energy conversion mechanisms (electromagnetic ...

(Phys.org)—The fundamental constants of nature—such as the speed of light, Planck's constant, and Newton's gravitational constant—are thought to be constant in time, as their name suggests. But scientists have questioned ...

(Phys.org)—Researchers have designed a nanoscale device that, under ideal conditions, can confine a "bit" of light (that is, light with a single precise energy value) for an infinite amount of time. Although a physically ...

(Phys.org)—Dissipation and decoherence are typically considered harmful to solar cell efficiency, but in a new paper scientists have shown that these effects paradoxically make the exciton lifetime in semiconducting carbon ...

(Phys.org)—High-energy protons, nuclei, and other particles are constantly showering down on Earth's atmosphere from space, but the origins of these cosmic rays is unknown. One possibility is that the cosmic rays come from ...

(Phys.org)—Flash memory—the data storage method often used in phones, computers, and other devices—is continually being miniaturized in order to improve device performance. In an attempt to reduce the short-circuiting that ...

(Phys.org)—In a quantum superposition, a quantum object can be in two incompatible states at the same time, which is famously illustrated by Schrödinger's dead-and-alive cat. Recent research has shown that it's possible to ...

(Phys.org)—Calling it an "Ode to Bubbles," MIT researchers have produced bubbling in sync with Beethoven's Symphony No. 9: Ode to Joy on a surface resembling a piano keyboard. The performance demonstrates the researchers' ...

(Phys.org)—When a kitchen sponge adsorbs water into its pores, it softens and expands. Now in a new study published in The Journal of Physical Chemistry Letters, scientists have discovered that, when microporous materials ...

(Phys.org)—When it comes to fabricating complex quantum devices, one limitation is the number of wires available on the measurement systems that the quantum devices are built on. Typically, controlling just three or four ...

(Phys.org)—In 1924, the mathematician David Hilbert described a hotel with an infinite number of rooms that are all occupied. Demonstrating the counterintuitive nature of infinity, he showed that the hotel could still accommodate ...

(Phys.org)—In 1876, the Austrian physicist Ludwig Boltzmann noticed something surprising about his equations that describe the flow of heat in a gas. Usually, the colliding gas particles eventually reach a state of thermal ...

(Phys.org)—Scientists have built a battery containing a magnetic fluid that can be moved in any direction by applying a magnetic field. The magnetically controlled battery concept could be especially useful for flow batteries, ...

(Phys.org)—A lot of attention has been given to the differences between the quantum and classical worlds. For example, quantum entanglement, superposition, and teleportation are purely quantum phenomena with no classical ...

Last August, the seasonal harmful algal blooms (HABs) in Lake Erie grew so extreme that they poisoned the water system in Toledo, Ohio, leaving nearly half a million residents without drinking water. But a few researchers ...
