A team of physicists has made groundbreaking observations in a semiconductor-based time crystal by periodically driving it with light. As the frequency was altered, the system transitioned from perfect synchronization to complex chaos, forming structures known as the Farey tree and the devil’s st
UNSW researchers interrogated the ‘sounds’ of a cluster of stars within the Milky Way, uncovering a new technique for astrophysicists to probe the universe and learn more about its evolution.
Astronomers at the University of Warwick have made an exciting discovery—a rare, high-mass compact binary star system located just 150 light-years away in the Milky Way. This marks the first time such a system has been observed, offering valuable insights into the origins of type 1a supernovae.
Astronomers have confirmed a pair of white dwarfs on a collision course to become a type 1a supernova—the brightest cosmic explosion. This system, the heaviest of its kind ever identified, has a combined mass of 1.56 times that of the sun.
Separated by only 1/60th of the Earth-sun distance, the stars currently orbit each other in just over 14 hours. However, gravitational wave radiation will gradually draw them closer over billions of years. On the verge of their explosive end, the stars will orbit so rapidly that a single orbit will take only 30–40 seconds.
Monash University researchers have extended Descartes’ Circle Theorem by finding a general equation for any number of tangent circles, using advanced mathematical tools inspired by physics. A centuries-old geometric puzzle dating back to the 17th century has finally been solved by mathematicians
Whether extra dimensions prove to be physical realities or useful mathematical constructs, they have already transformed our understanding of the universe. They have forced us to reconsider fundamental assumptions about space, time, and the nature of physical law. And they remind us that reality may be far richer and more complex than our everyday experience suggests — that beyond the familiar dimensions of length, width, height, and time, there may exist entire realms waiting to be discovered and, perhaps one day, explored.
The theoretical physicist John Wheeler once remarked that “we live on an island of knowledge surrounded by an ocean of ignorance.” Our exploration of extra dimensions extends the shoreline of that island, pushing into uncharted waters with the tools of mathematics, experiment, and imagination. Though we may never set foot in the fifth dimension or beyond, the very act of reaching toward these hidden aspects of reality expands our perspective and deepens our understanding of the cosmos we call home.
As we continue this grand scientific adventure, we carry forward the legacy of those who first dared to imagine worlds beyond our immediate perception — from the mathematicians who developed the language of higher-dimensional geometry to the physicists who incorporated these concepts into our most fundamental theories. Their vision, coupled with rigorous analysis and experimental testing, illuminates a path toward an ever more complete understanding of the universe in all its dimensions.
The world of robotics is undergoing a significant transformation, driven by rapid advancements in physical AI. This evolution is accelerating the time to market for new robotic solutions, enhancing confidence in their safety capabilities, and contributing to the powering of physical AI in factories and warehouses.

Physicists at TU Dortmund University have periodically driven a time crystal and discovered a remarkable variety of nonlinear dynamic phenomena, ranging from perfect synchronization to chaotic behavior within a single semiconductor structure. The team has now published its latest findings in the journal Nature Communications.
For their current research, Dr. Alex Greilich’s team from the Department of Physics utilized a highly robust time crystal, previously introduced in Nature Physics last year. The crystal, made of indium gallium arsenide, was continuously illuminated with a laser during the initial experiment. This interaction caused a nuclear spin polarization, which in turn spontaneously generated oscillations, embodying the essence of a time crystal through periodic behavior under constant excitation.
In the newly published follow-up study, the team explored the dynamic phases of the time crystal. They illuminated the semiconductor periodically instead of continuously, while also varying the frequency of the periodic drive. The observed behavior of the time crystal, its frequency response, ranged from perfect synchronization to chaotic dynamics.
A new paper explains how signals oscillating at complex-valued frequencies could transform sensing, imaging, and communication technologies. Researchers from the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) and Florida International University have published new findin
Heaviside was born in Camden Town, London, at 55 Kings Street [ 3 ] : 13 (now Plender Street), the youngest of three children of Thomas, a draughtsman and wood engraver, and Rachel Elizabeth (née West). He was a short and red-headed child, and suffered from scarlet fever when young, which left him with a hearing impairment. A small legacy enabled the family to move to a better part of Camden when he was thirteen and he was sent to Camden House Grammar School. He was a good student, placing fifth out of five hundred students in 1865, but his parents could not keep him at school after he was 16, so he continued studying for a year by himself and had no further formal education. [ 4 ] : 51
Heaviside’s uncle by marriage was Sir Charles Wheatstone (1802–1875), an internationally celebrated expert in telegraphy and electromagnetism, and the original co-inventor of the first commercially successful telegraph in the mid-1830s. Wheatstone took a strong interest in his nephew’s education [ 5 ] and in 1867 sent him north to work with his older brother Arthur Wheatstone, who was managing one of Charles’ telegraph companies in Newcastle-upon-Tyne. [ 4 ] : 53
Two years later he took a job as a telegraph operator with the Danish Great Northern Telegraph Company laying a cable from Newcastle to Denmark using British contractors. He soon became an electrician. Heaviside continued to study while working, and by the age of 22 he published an article in the prestigious Philosophical Magazine on ‘The Best Arrangement of Wheatstone’s Bridge for measuring a Given Resistance with a Given Galvanometer and Battery’ [ 6 ] which received positive comments from physicists who had unsuccessfully tried to solve this algebraic problem, including Sir William Thomson, to whom he gave a copy of the paper, and James Clerk Maxwell. When he published an article on the duplex method of using a telegraph cable, [ 7 ] he poked fun at R. S. Culley, the engineer in chief of the Post Office telegraph system, who had been dismissing duplex as impractical.
