Researchers tracked galaxy clusters to test gravity's strength, finding it weakens with distance as predicted by Newton and Einstein. The study confirms the existence of invisible dark matter, closing the door on alternative theories like Modified Newtonian Dynamics.
University of Missouri researchers are helping farmers prevent disease outbreaks by teaching biosecurity practices, such as hand sanitizing and wearing farm-dedicated shoes. They also provide guidance on safe composting methods to dispose of dead livestock, reducing the risk of disease spread.
Researchers at WVU are enhancing the calibration of radio telescopes to measure dark energy by analyzing the '21-centimeter signal' from neutral hydrogen atoms. This technique aims to improve the ability of radio telescopes to detect large-scale structures in the universe, such as galaxy clusters and voids.
The Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe’s infancy. These new images show subtle variations in density and velocity of gases in the young universe, helping scientists answer longstanding questions about the universe’s origins.
A team of scientists has identified key sources of radiation that can interfere with superconducting qubits, leading to errors in quantum computing. By developing effective shielding measures, they aim to improve coherence times and pave the way for practical quantum computing.
A new study has sorted through models attempting to solve the cosmological tension, a discrepancy between two ways of calculating the universe's expansion. Three models that were previously viable solutions were excluded by the new data, while others reduced the tension but not solved it.
The new CLASS maps provide further insight into linear polarization, helping scientists study the Milky Way but also studying the early universe. The results significantly improve observations, allowing for a better understanding of the cosmic microwave background and its implications on the universe's origins.
Scientists will use the Simons Observatory to uncover secrets hidden in the cosmic tapestry, revealing mysteries of the universe with unparalleled precision. The observatory's completion marks a major milestone in understanding the cosmos.
Researchers from Queen's University have identified two potential polar ring galaxies using data from the CSIRO's ASKAP radio telescope.

Researchers from the US and Germany report a realistic contender to measure the elusive neutrino mass using Cyclotron Radiation Emission Spectroscopy. The project tracks electrons generated by beta decay to reveal the neutrino mass, aiming for scalability beyond existing technology.
Researchers propose using lensed gravitational waves from binary black holes to measure cosmic expansion. The method uses the delays between repeat appearances of these signals to encode the universe's expansion rate. This approach does not rely on knowing the exact locations or distances of binary black holes, making it a promising to...
A team of researchers from the University of Minnesota has successfully measured the expansion rate of the Universe using data from a magnified supernova. Their findings provide new insight into the problem and bring scientists closer to obtaining the most accurate measurement of the Universe's age.
A study published in the Astrophysical Journal reveals a strong correlation between cosmic ray counts and the solar cycle at Mars and Venus. The research found that cosmic rays are suppressed during peak solar activity, highlighting the importance of understanding these interactions for future robotic missions and human exploration.
A new Northwestern Medicine study identifies common and rare gene mutations that impact radiation resistance and sensitivity. This information will allow clinicians to better calibrate radiation doses based on genetic mutations, improving treatment efficacy while reducing toxicity.
Researchers used microwaves from the cosmic microwave background to measure dark matter distribution around distant galaxies. The findings suggest a different clumpiness measurement than predicted by the Lambda-CDM model, hinting at a possible flaw in the current cosmology theories.
Physicists Lawrence Krauss and Frank Wilczek suggest measuring minute changes in the cosmic background radiation could detect telltale effects of gravitons. They propose that gravitons exist as 'quantum fluctuations' during inflation, generating gravitational waves that affect CMB polarization.
Scientists at Penn State University developed a new paradigm for understanding the earliest eras of the universe, extending analyses to the Big Bang using loop quantum cosmology. The research reveals that fundamental fluctuations in space-time evolved into large-scale structures, challenging classical physics and inflationary theories.
New data reveals galaxies formed and fully illuminated the universe by 750 million years old, ending sooner than expected. The epoch of reionization lasted less than 500 million years and was triggered by monster galaxies with over a billion stars.
A team of Rutgers and Chilean astrophysicists has discovered 10 new massive galaxy clusters, shedding light on the universe's birth and evolution. The breakthrough technique uses 'cosmic shadows' to reveal these previously unseen clusters.
The Lunar Array for Radio Cosmology (LARC) project aims to explore the 'Dark Ages' of the universe when stars and galaxies first formed. The new telescopes will study cosmic background radiation and test current theories about the universe's formation.
Marc Kamionkowski has been awarded the Helen B. Warner Prize for his significant contributions to cosmology, astrophysics, and particle physics. His research focuses on the cosmic microwave background radiation and its potential to clarify the origins of the universe.
