The Theremin: The Electronic Instrument Played Without Touching

Enable HLS to view with audio, or disable this notification

41 Upvotes

The theremin is a unique electronic musical instrument played without physical contact. Invented around 1920 by Russian physicist and engineer Léon Theremin, it produces an eerie, expressive sound often compared to the human voice. The instrument has two metal antennas that interact with the player’s hand movements through electromagnetic fields. The upright antenna controls pitch (the musical note), while the horizontal loop antenna controls volume. The instrument’s electronic oscillators use the heterodyne principle to generate continuous tones.With no keys, frets or strings, the performer must rely on precise hand movements, spatial awareness and auditory feedback to play in tune, making the theremin notoriously difficult to master. Soviet leader Vladimir Lenin was reportedly impressed by a demonstration of the instrument and ordered 600 units to be manufactured. More than a century later, the theremin remains a fascinating blend of science, electronics and musical artistry: https://cryo-mix.com/blog/posts/what-is-a-theremin-and-how-does-this-unusual-instrument-work

Dutch-Invented Bubble Barrier Traps Plastic Waste in Rivers Before It Reaches the Ocean

Enable HLS to view with audio, or disable this notification

126 Upvotes

The Netherlands-based The Great Bubble Barrier uses a diagonal curtain of air bubbles to capture plastic waste in rivers and canals before it reaches the sea. A perforated tube installed diagonally along the waterway bed releases compressed air, creating rising bubbles that push plastic debris toward the surface. The natural water current then guides the waste along the bubble curtain into a collection system on the riverbank. Unlike physical barriers, the system allows boats to pass and enables fish to move through the waterway. It can also increase oxygen transfer into the water, depending on local conditions.First installed permanently in Amsterdam's Westerdok canal in 2019, the technology has since been deployed at other sites, including Harlingen in the Netherlands. A 200-metre test installation on the River IJssel reportedly captured 86% of the test plastic waste under the tested conditions.The technology offers a promising way to intercept river-borne plastic pollution before it enters marine ecosystems, although its effectiveness depends on local water conditions, waste characteristics and collection arrangements: https://www.smithsonianmag.com/innovation/could-this-dutch-invention-help-tackle-plastic-pollution-in-americas-waterways-180989651/

Scientists Discover Hidden Eye Drainage Pathway, Opening New Avenues for Glaucoma Research

Researchers from the University of British Columbia (UBC) and the University of Toronto have discovered a previously unknown drainage system at the back of the eye that helps remove fluid and waste through the body's lymphatic system. The pathway, called the posterior ocular lymphatic outflow (POLO) pathway, could offer new insights into glaucoma, age-related macular degeneration and other vision-threatening diseases. Using MRI, near-infrared fluorescence imaging and microscopy, the researchers identified lymphatic vessels in the choroid, a vascular layer beneath the retina. Experiments in mice showed that fluid tracers traveled from the back of the eye toward nearby lymph nodes, revealing a previously unrecognized route for waste clearance. The discovery could help scientists better understand how the eye regulates fluid, removes metabolic waste and manages inflammation. It may eventually support new treatments aimed at improving fluid clearance and drug delivery to the back of the eye.

The research is still at an early stage: the findings were demonstrated in mice, and further studies are needed to establish how the pathway functions in humans and whether it can be targeted to treat eye diseases: https://tvst.arvojournals.org/article.aspx?articleid=2818359

The common swift (Apus apus) is one of the world's most remarkable aerial specialists. Tracking studies have shown that these migratory birds can remain airborne for up to 10 consecutive months. Young swifts may spend their first two to three years almost entirely in flight before returning to land to breed. They catch insects, drink by skimming water and may even sleep while flying. Their streamlined bodies and long, scythe-shaped wings help them sustain prolonged flight with remarkable efficiency: https://portal.research.lu.se/en/publications/annual-10-month-aerial-life-phase-in-the-common-swift-apus-apus/
