Two black holes merged into the new one, and got a high speed ‘kick’

High-Speed Cosmic Kick: A New Black Hole Discovery

A newly formed black hole recently received a high-speed “kick,” thanks to gravitational waves, which propelled it at about 5 million kilometers per hour—roughly 200 times the speed of light. This surprising discovery was made through data collected by gravitational wave observatories LIGO and Virgo. These observatories detected spacetime ripples produced by the coalescence of two black holes on January 29, 2020, revealing the large recoil effect.

Quasar ‘clocks’ show the universe ran five times slower right after the Big Bang

For the first time, scientists have measured the early universe running in extreme slow motion, showing that time was five times slower just a billion years after the Big Bang. By studying nearly 200 quasars – hyperactive supermassive black holes at the centers of ancient galaxies – researchers have provided new evidence for Einstein’s theory of general relativity regarding an expanding universe.

The Mystery of Early Universe Time Dilation

Einstein’s general theory of relativity predicts that, as the universe expands, distant objects (and therefore the early universe) should appear to experience slower time. However, directly observing this has been challenging due to the vast distances and the faint signals coming from early cosmic phenomena. Previous research had established this dilation back to half the age of the universe using supernovae, but quasars have now pushed this further back to just a tenth of the universe’s age.

A simple model for an intricate, ever-evolving structure

Scientists use math and physics to address the mystery of just how the endoplasmic reticulum, an organelle essential to life at the cellular level, continually re-arranges itself.

Nanoislands on silicon enable switchable topological textures for new electronic applications

Ferroelectrics at the nanoscale exhibit a wealth of polar and sometimes swirling (chiral) electromagnetic textures that not only represent fascinating physics, but also promise applications in future nanoelectronics. For example, ultra-high-density data storage or extremely energy-efficient field-effect transistors. However, a sticking point has been the stability of these topological textures and how they can be controlled and steered by an external electrical or optical stimulus.

A team led by Prof. Catherine Dubourdieu (HZB and FU Berlin) has now published a paper in Nature Communications that opens up new perspectives. Together with partners from the CEMES-CNRS in Toulouse, the University of Picardie in Amiens and the Jozef Stefan Institute in Ljubljana, they have thoroughly investigated a particularly interesting class of nanoislands on silicon and explored their suitability for electrical manipulation.

“We have produced BaTiO3 nanostructures that form tiny islands on a silicon substrate,” explains Dubourdieu. The nano-islands are trapezoidal in shape, with dimensions of 30–60 nm (on top), and have stable polarization domains.

SMART: One step closer to nuclear fusion with its first plasma

In a pioneering approach to achieve fusion energy, the SMART device has successfully generated its first tokamak plasma. This step brings the international fusion community closer to achieving sustainable, clean, and virtually limitless energy through controlled fusion reactions.

The work is published in the journal Nuclear Fusion.

The SMART tokamak, a state-of-the-art experimental fusion device designed, constructed and operated by the Plasma Science and Fusion Technology Laboratory of the University of Seville, is a unique spherical tokamak due to its flexible shaping capabilities. SMART has been designed to demonstrate the unique physics and engineering properties of Negative Triangularity shaped plasmas towards compact fusion power plants based on Spherical Tokamaks.

Chinese ‘artificial sun’ sets a record towards fusion power generation

The Experimental Advanced Superconducting Tokamak (EAST), commonly known as China’s “artificial sun,” has achieved a remarkable scientific milestone by maintaining steady-state high-confinement plasma operation for an impressive 1,066 seconds. This accomplishment, reached on Monday, sets a new world record and marks a significant breakthrough in the pursuit of fusion power generation.

The duration of 1,066 seconds is a critical advancement in fusion research. This milestone, achieved by the Institute of Plasma Physics (ASIPP) at Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences, far surpasses the previous world record of 403 seconds, also set by EAST in 2023.

The ultimate goal of developing an artificial sun is to replicate the nuclear fusion processes that occur in the sun, providing humanity with a limitless and clean energy source, and enabling exploration beyond our solar system.

Spin has transformed modern-day tennis—here’s the physics behind it

Watch any match at this year’s Australian Open and you’ll see balls curving in the air or bouncing higher or lower than expected. Players such as Novak Djokovic, Iga Swiatek and Coco Gauff are particularly masterful at the art.

The secret? It’s all about spin.

The ability to control a tennis ’s spin has transformed the modern game, making it faster and more spectacular than ever. But how exactly do players make the ball move through the air or bounce off the court like that?
