9 D Universe

Astronomers have surveyed massive, dense star factories, unlike any found in the Milky Way, in a large number of galaxies across the local universe. The findings provide a rare glimpse into processes shaping galaxies in the very early universe and possibly the Milky Way a few billion years from now. [...]

The Heisenberg uncertainty principle holds things together. Articulated by the German physicist Werner Heisenberg almost a century ago, it remains the foundation of the physical world. Its name suggests the rule of the vague and temporary. But the principle is quantitative. A high uncertainty about the position of, say, an [...]

Thanks to a new sound-based control system, a microfluidic processor can precisely manipulate droplets with an exceptionally broad range of volumes. The minimalist device is compatible with many substrates, including metals, polymers and glass. It is also biocompatible, and its developers at the Hong Kong Polytechnic University say it could [...]

For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the Big Bang. [...]

The first session at the Helgoland 2025 meeting marking the centenary of quantum mechanics began with the four Nobel-prize-winning physicsts in attendance being invited on stage to sign the island’s memorial “gold book” and add a short statement to it. Anton Zeilinger and Alain Aspect, who shared the 2022 Nobel prize [...]

Astronomers have discovered the largest known cloud of energetic particles surrounding a galaxy cluster—spanning nearly 20 million light-years. The finding challenges long-standing theories about how particles stay energized over time. Instead of being powered by nearby galaxies, this vast region seems to be energized by giant shockwaves and turbulence moving [...]

New research led by Dr. James De Buizer at the SETI Institute and Dr. Wanggi Lim at IPAC at Caltech revealed surprising results about the rate at which high-mass stars form in the galactic center of the Milky Way. The researchers based their study primarily on observations from NASA's now-retired [...]

Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has co-authored a paper that uses young stars to develop a more accurate map of the outer gas disk of the Milky Way galaxy. [...]

“This is a birthday party! Happy 100th birthday quantum mechanics,” said Jack Harris from Yale University in the US to whoops and cheers in the banqueting suite of the Hotel Atlantic in Hamburg, Germany. Harris was addressing the 300 or so physicists attending the Helgoland 2025 conference, which is taking place from [...]

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA's Chandra X-ray Observatory. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the Big Bang itself. [...]

Year 12 students (aged 16 or 17) often do work experience while studying for their A-levels. It can provide valuable insights into what the working world is like and showcase what potential career routes are available. And that’s exactly why I requested to do my week of work experience at the Institute [...]

Artificial intelligence (AI) holds great potential for a range of data-intensive healthcare tasks: detecting cancer in diagnostic images, segmenting images for adaptive radiotherapy and perhaps one day even fully automating the radiation therapy workflow. Now, for the first time, a team at Northwestern Medicine in Illinois has integrated a generative AI [...]

New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from? [...]

Just over a week ago, US President Donald Trump released a budget proposal that would, if enacted, eviscerate science research across the country. Among other cuts, it proposes a 57% drop (relative to 2024) in funding for the National Science Foundation (NSF), which provides the lion’s share of government support [...]

MIT Plasma Science and Fusion Center to establish the Schmidt Laboratory for Materials in Nuclear Technologies. Fusion energy has the potential to enable the energy transition from fossil fuels, enhance domestic energy security, and power artificial intelligence. Private companies have already invested more than $8 billion to develop commercial fusion and seize [...]
