Scientists apply principles of math and physics to unravel the mystery of how the endoplasmic reticulum, an organelle vital to cellular life, constantly reshapes and reorganizes itself. As a second-year Ph.D. student and physicist, Zuben Scott hadn’t thought much about the endoplasmic reticulum s
Scientists in Korea achieved the first experimental realization of bound states in the continuum in a single resonator, opening doors to ultra-efficient wave control for future tech. A research team from POSTECH (Pohang University of Science and Technology) and Jeonbuk National University has ach
Earth rotates, the Sun rotates, the Milky Way rotates – and a new model suggests the entire Universe could be rotating. If confirmed, it could ease a significant tension in cosmology.
The Universe is expanding, but exactly how fast is a contentious question. Two different methods of measurement return two very different speeds – and as the measurements become more precise, each becomes more certain. This discrepancy is known as the Hubble tension, and it’s reaching crisis levels in physics.
So for a new study, physicists in Hungary and the US added a small rotation to a model of the Universe – and this mathematical massage seemed to quickly ease the tension.
A paper published in 2024 theorizes that time may have existed before the Big Bang, but we’re still not entirely sure.
Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window into the universe. To observe them, ultra-precise detectors are required, but designing them remains a major scientific challenge for humans.
Researchers at the Max Planck Institute for the Science of Light (MPL) have been working on how an artificial intelligence system could explore an unimaginably vast space of possible designs to find entirely new solutions. The results were recently published in the journal Physical Review X.
More than a century ago, Einstein theoretically predicted gravitational waves. They could only be directly detected in 2016 because the development of the necessary detectors was extremely complex.

If this scenario plays out, “the world as we know it would collapse like a house of cards,” says one theoretical physicist.
A team of chemical and biomolecular engineers, physicists and battery specialists affiliated with several institutions in the U.S. has developed a water-based battery that offers 2,000-cycle stability. In their paper published in the journal Nature Nanotechnology, the group outlines why they believe it could help bridge the gap between aqueous batteries and non-aqueous lithium-ion batteries.
The main advantage of using aqueous batteries is their safety compared to nonaqueous, lithium-ion batteries. They cannot ignite unexpectedly, minimizing fire hazard. The reason that they are not common is their reduction potential limit of aqueous electrolytes, which has restricted their energy density. Also, the current types of electrolytes they use tend to have problems with water shuttling the interface and high impedance.
In this new study, the research team has taken a step toward resolving these problems by improving ion transport and the stability of biphasic electrolytes via lithium ionophores.
Here in this video today we will explore something that has been demanded by viewers of the channel for quite sometime, the Xeelee rings, one of the largest megastructures in fiction. We first have to take a look at the universe we are discussing about. So, The Xeelee Sequence is a series of science fiction novels and short stories by British author Stephen Baxter, exploring the grand scale of the universe from the Big Bang to its ultimate end. The series follows humanity’s evolution over billions of years, its conflicts with alien species, and the mysterious, hyper-advanced Xeelee, who are engaged in a cosmic war against the enigmatic dark matter entities known as the Photino Birds. The books blend hard science fiction with cosmic wonder, delving into themes of time travel, black hole physics, alternate universes, and the limits of human potential. Major works in the series include \.
