Study reveals that the speed of cognitive information processing stays exceptionally stable over decades Mental speed– the speed at which we can manage problems needing quick decision-making– does not change significantly over the years. Psychologists at Heidelberg University came to this conclusion under the leadership of Dr. Mischa von Krause and Dr. Stefan Radev. They […]

An autonomously swimming biohybrid fish, designed to emphasize two crucial regulatory functions of the human heart, has shown the relevance of feedback mechanisms in muscle pumps (such as the heart). The discoveries can one day help inform the development of an artificial heart developed from living muscle cells. Autonomously swimming biohybrid fish Biohybrid systems– devices
On February 9, the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) published the Clinical Practice Guideline: Tympanostomy Tubes in Children (Update) in Otolaryngology-Head and Neck Surgery. Tympanostomy tubes, also called ear tubes, effectively lower or eliminate middle ear infections and eliminate persistent middle ear fluid and hearing loss related to middle ear fluid.

Could a laser send a spacecraft to Mars? That is a proposed mission from a group at McGill University, made to fulfill a solicitation from NASA. The laser, a 10-meter vast array in the world, would certainly heat up hydrogen plasma in a chamber behind the spacecraft, creating thrust from hydrogen gas and sending it

Ferromagnetic materials possess a self-generating magnetic field; ferroelectric materials create their own electrical field. Electric and magnetic fields are important. Physics tells us that they are entirely different classes of material. Now the finding by University of Warwick-led scientists of a complex electrical ‘vortex-like’ pattern that mirrors its magnetic equivalent indicates that they could actually

We are in for an information revolution. Engineers in Japan demolished the world record for the fastest internet speed, reaching a data transmission rate of 319 Terabits per second (Tb/s), according to a paper presented at the International Conference on Optical Fiber Communications in June. This new record was made on a line of fibers

As chemists struggle to discover methods to reclaim important metals from industrial waste and disposed electronics, one group has discovered an answer that seems a little like magic: Zap the trash with flashes of electric heat. Rare earth elements (REEs) introduce an environmental paradox. On the one hand, these dozen or so metals, such as

If you or somebody you know experiences feelings of anxiety, mood swings, mild depression, panic attacks, or obsessive thoughts, this article could be what you have been searching for. Any dysfunctional mental state often results from a brain trapped in the beta state of brainwave activity. We associate this state with overthinking, rumination, negativity bias,
The global supply chain is presently experiencing all kinds of glitches, from material scarcities to labor scarcities and beyond. Moving goods from one point to another has become much more expensive, and there is no quick fix in sight. However, a San Diego-based start-up plans to meet some of the demand for air cargo with
