Researchers at TU Delft have discovered that E. coli bacteria can synchronize their movements, creating order in seemingly random biological systems. By trapping individual bacteria in micro-engineered circular cavities and coupling these cavities through narrow channels, the team observed coordinated bacterial motion. Their findings, which have potential applications in engineering controllable biological oscillator networks, were recently published in Small. https://phys.org/news/2024-12-tiny-dancers-scientists-synchronize-bacterial.html Bio & Medicine Tue, 03 Dec 2024 16:41:18 EST news652466465 Though Saturn's unusual-looking "cup handle" features were first noted by Galileo in 1610, it would be another 45 years before they were described by Christiaan Huygens as a disk surrounding Saturn. Subsequently, ground-based telescopes could only distinguish four unique concentric rings, labeled A, B, C, and D. https://phys.org/news/2023-12-nasa-hubble-spoke-season-saturn.html Astronomy Thu, 21 Dec 2023 11:52:07 EST news622381922 Since the 17th century, when Isaac Newton and Christiaan Huygens first debated the nature of light, scientists have been puzzling over whether light is best viewed as a wave or a particle—or perhaps, at the quantum level, even both at once. Now, researchers at Stevens Institute of Technology have revealed a new connection between the two perspectives, using a 350-year-old mechanical theorem—ordinarily used to describe the movement of large, physical objects like pendulums and planets—to explain some of the most complex behaviors of light waves. https://phys.org/news/2023-08-physicists-year-old-theorem-reveal-properties.html Optics & Photonics Mon, 21 Aug 2023 17:14:03 EDT news611856841 In a paper published today in Nature Communications, researchers from the Paul Drude Institute in Berlin, Germany, and the Instituto Balseiro, Bariloche, Argentina, demonstrated that light emitters with different resonance frequencies can asynchronously self-lock their relative energies by exchanging mechanical energy. This finding paves the way for increased control of light sources and GHz-to-THz interconversion relevant to quantum technology. https://phys.org/news/2023-06-self-locking-sources-opportunities-quantum-technologies.html Condensed Matter Mon, 19 Jun 2023 09:56:04 EDT news606387362 Christiaan Huygens built excellent lenses in the 17th century, but his telescopes lacked sharpness in comparison with what was possible at that time. In a recent study, Dr. Alex Pietrow, researcher at the Leibniz Institute for Astrophysics Potsdam (AIP), investigated Huygens' calculations and has concluded that the Dutch astronomer and mathematician was probably near-sighted and would have needed eyeglasses to improve his telescopes. https://phys.org/news/2023-03-eyeglasses-prescription-christiaan-huygens-years.html Astronomy Thu, 02 Mar 2023 10:41:51 EST news596976106 In 1665 Christiaan Huygens discovered that two pendulum clocks, hung from the same wooden structure, will always oscillate in synchronicity. Today, some 350 years on, Eindhoven and Mexican researchers present the most accurate and detailed description of this 'Huygens synchronization' to date in the journal Scientific Reports. It is evident that Huygens had come up with the right explanation insofar as this was possible back then. Moreover, these insights help us to understand synchronization in all kinds of oscillating systems, such as the biological rhythms of the human body. https://phys.org/news/2016-03-huygens-pendulum-synchronization.html General Physics Tue, 29 Mar 2016 09:07:27 EDT news378461238 Almost 350 years ago, Dutch inventor and scientist Christiaan Huygens observed that two pendulum clocks hanging from a wall would synchronise their swing over time. https://phys.org/news/2015-07-tic-toc-pendulums-harmony.html General Physics Thu, 23 Jul 2015 14:30:01 EDT news356878821 (Phys.org) —This colourful cosmic rainbow portrays a section of Saturn's beautiful rings, four centuries after they were discovered by Galileo Galilei. https://phys.org/news/2014-05-nasa-image-saturn-rainbow.html Space Exploration Tue, 06 May 2014 06:59:48 EDT news318578379 (Phys.org) —A 350-year-old mathematical mystery could lead toward a better understanding of medical conditions like epilepsy or even the behavior of predator-prey systems in the wild, University of Pittsburgh researchers report. https://phys.org/news/2013-06-pendulum-year-old-mathematical-mystery.html Mathematics Mon, 10 Jun 2013 12:03:54 EDT news290084623 Phase synchronization is a phenomenon in which separate oscillatory systems develop joint coherent behavior by some nonlinear mechanism. First described in 1673 by Dutch scientist Christiaan Huygens, this phenomenon occurs for instance when an applauding audience suddenly starts to clap in unison or when human breathing patterns lock to multiples of the heart beat. https://phys.org/news/2011-09-el-nino-tropical-eastern-pacific.html Earth Sciences Thu, 22 Sep 2011 10:10:13 EDT news235904967 (PhysOrg.com) -- A team of structural engineers from the University of Sheffield in the UK say the assumptions originating with 17th century Dutch engineer Christiaan Huygens may need to be re-examined. Huygens assumed the best design for a suspension bridge was based on towers and simple cables hanging between them to support the weight, but the Sheffield group say a more complex design using less material would be more efficient. https://phys.org/news/2010-01-suspension-bridge.html Engineering Fri, 15 Jan 2010 11:48:13 EST news182778453
