A new attempt to explain the accelerated expansion of the universe

Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern physics. Because it cannot be fully answered using our current physical worldview, researchers assume the existence of a mysterious “dark energy.” However, its origin remains unclear to this day.

Team uncovers intrinsic binary fraction of blue horizontal-branch stars

A research team from the Yunnan Observatories of the Chinese Academy of Sciences has conducted a study on the binary fraction of blue horizontal-branch (BHB) stars. Their findings, recently published in Astronomy & Astrophysics, provide the intrinsic binary fraction and reveal its relationship with metallicity, kinematics, and effective temperature.

Are there living microbes on Mars? Check the ice, researchers say

Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the red planet. By recreating Mars-like conditions in the lab, a team of researchers from NASA Goddard Space Flight Center and Penn State demonstrated that fragments of the molecules that make up proteins in E. coli […]

Researchers pioneer fluid-based laser scanning for brain imaging

When Darwin Quiroz first started working with optics as an undergraduate, he was developing atomic magnetometers. That experience sparked a growing curiosity about how light interacts with matter, an interest that has now led him to a new technique in optical imaging.

Amplifying collective light emission with atomic interactions

A team of physicists from the Faculty of Physics at the University of Warsaw, the Center for New Technologies at the University of Warsaw and Emory University (Atlanta, U.S.) analyzed how atoms’ mutual interactions change the way they collectively interact with light.

Our team of physicists inadvertently generated the shortest X-ray pulses ever observed

X-ray beams aren’t used just by doctors to see inside your body and tell whether you have a broken bone. More powerful beams made up of very short flashes of X-rays can help scientists peer into the structure of individual atoms and molecules and differentiate types of elements.

Gaia provides a deep look into the galactic open cluster NGC 2506

Using ESA’s Gaia satellite and NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers from the Ege University in Turkey and elsewhere have observed a galactic open cluster known as NGC 2506. Results of the observational campaign, published October 7 on the arXiv pre-print server, put more constraints on the properties of this cluster.

Physicists probe quark‑gluon plasma temperatures, helping paint more detailed picture of Big Bang

A research team led by Rice University physicist Frank Geurts has successfully measured the temperature of quark-gluon plasma (QGP) at various stages of its evolution, providing critical insights into a state of matter believed to have existed just microseconds after the Big Bang, a scientific theory describing the origin and evolution of the universe.

Here Is A List Of The Largest Monoliths Ever Created By Ancient Civilizations

Massive monoliths quarried by man can be found all over the planet.

The most straightforward definition of a monolith? A monolith can be a large piece of rock that is intended or was used to build a structure or a monument, alone or together with other stones.

Ancient mankind has had the ability to […]

Why some quantum materials stall while others scale

People tend to think of quantum materials—whose properties arise from quantum mechanical effects—as exotic curiosities. But some quantum materials have become a ubiquitous part of our computer hard drives, TV screens, and medical devices. Still, the vast majority of quantum materials never accomplish much outside of the lab.

Changing-look active galactic nucleus investigated by researchers

By analyzing the available data from various space observatories and ground-based telescopes, Indian astronomers have conducted a long-term multiwavelength study of a changing-look active galactic nucleus (AGN) known as NGC 3822. Results of the new study, published October 7 on the arXiv pre-print server, provide more insights into the behavior of this AGN.

Record-breaking gamma ray burst seems to be caused by a black hole engulfed by a bloated star

On July 2, 2025, NASA’s Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours’ worth of signals that appeared to come from the same source. When scientists compiled this data with signals picked up by multiple other instruments, like the Einstein Probe (EP) Wide-field X-ray Telescope and the Russian gamma-ray spectrometer, Konus-Wind, they found that […]
