Dark energy makes up roughly 70% of the universe, yet we know nothing about it.
Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and touch—matter made up of atoms.
Dark energy is the placeholder name scientists have given to the unknown force causing the universe to expand faster and faster over time.
When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His gravitational model showed how Newtonian gravity, which had dominated astronomy and physics for more than three centuries, was merely an approximation of a more subtle and elegant model.
Einstein showed us that gravity is not a mere force but is rather the foundation of cosmic structure. Gravity, Einstein said, defined the structure of space and time itself.
But in the past century, we have learned far more about the cosmos than even Einstein could have imagined. Some of our observations, such as gravitational lensing clearly confirm general relativity, but others seem to poke holes in the model. The rotational motion of galaxies doesn’t match the predictions of gravity alone, leading astronomers to introduce dark matter.

Despite testing negative for rheumatoid arthritis, doctors diagnosed her with the condition after four months of visits.
However, the 40-year-old, who owns a marketing company, soon experienced excruciating stomach pains and a dramatic 14-pound weight loss within a month, with doctors attributing it to acid reflux.
Unsatisfied and desperate for answers, Bannon turned to the AI chatbot developed by OpenAI for a potential diagnosis, which she had been using for work.
Scientists in Germany have crafted “skyrmion bags” of light—complex vortex-like structures—on the surface of gold by cleverly manipulating how laser beams interact with nano-etched patterns.
This unusual feat not only adds a surprising twist to the physics of light but also hints at future technologies that could break the limits of current microscopes.
Skyrmion light bags: a new breakthrough
But now, a bold new idea is challenging this tidy system. Scientists at Rice University in Texas believe there may be a third kind of particle—one that doesn’t follow the rules of fermions or bosons. They’ve developed a mathematical model showing how these unusual entities, called paraparticles, could exist in real materials without breaking the laws of physics.
“We determined that new types of particles we never knew of before are possible,” says Kaden Hazzard, one of the researchers behind the study. Along with co-author Zhiyuan Wang, Hazzard used advanced math to explore this idea.
Their work, published in Nature, suggests that paraparticles might arise in special systems and act differently than anything scientists have seen before.
Sam Parnia, associate professor at New York University, suggests that death can be reversed and our brains may remain salvageable for hours or days after death. He emphasizes that death can be viewed as an injury process, with the potential for revival through ECMO machines and specific drugs used in CPR cocktails to aid recovery.
The global proliferation of antibiotic resistance genes (ARGs) poses a significant threat to the efficacy of antibiotic-based treatments for diseases. Effective monitoring of ARGs across both spatial and temporal dimensions is essential to understanding their transmission and implementing preventive measures.
A research team has developed a computational tool, Argo, designed to accurately track ARGs in environmental samples, providing insights into their dissemination and associated risks.
“Short-read sequencing method is currently used as a high-throughput DNA sequencing technique that generates large volumes of short DNA fragments, typically 150 base pairs. However, it often fails to provide information on the hosts of ARGs,” explained the senior author. “Without detailed host information, it becomes challenging to accurately assessing the risks of ARGs and tracing their transmission, hindering our understanding of their impact on human health and the environment.”
