Phys.org / Opinion: Is world peace even possible? I study war and peace, and here's where I'd start
By any measure, 2025 was not a good year for world peace.
Medical Xpress / Australia's red and yellow beach flags can be dangerously confusing. Is it time to change them?
Every summer in Australia, millions of people head to the beach, and every year, thousands are rescued by lifeguards or Surf Life Savers and even surfers or other bystanders. Tragically, many people lose their lives on our ...
Phys.org / Real-life experiment shows Niels Bohr was right in a theoretical debate with Einstein
Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by Niels Bohr and his school ...
Phys.org / Finding runaway stars to help map dark matter in the Milky Way
Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the Milky Way galaxy, such as its gravitational potential and the distribution of matter. Now astronomers ...
Phys.org / Climate policies can backfire by eroding 'green' values, study finds
A popular vision of life after climate action looks like vegetarians riding bikes, city centers without cars, and people foregoing air travel. But a new paper published in Nature Sustainability finds that climate policies ...
Phys.org / Searching for light dark matter by tracking its direction with quantum sensors
Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using conventional technologies used by ...
Phys.org / Can Australian sport ever be environmentally sustainable?
Sport is one of the most climate-sensitive aspects of Australian life, yet still sits largely outside the national conversation on climate exposure.
Phys.org / Hunting for dark matter axions with a quantum-powered haloscope
Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some nuclear interactions don't violate time symmetry and are also promising dark matter candidates. Dark ...
Phys.org / Most sensitive radio observations to date find no evidence of technosignature from 3I/ATLAS
Since the interstellar object (ISO) 3I/ATLAS was first discovered on July 1, 2025, it has garnered much attention, including speculation, hopes and fears that it may somehow contain evidence of technologically advanced civilizations ...
Phys.org / The Star of Bethlehem might have actually been a comet described in an ancient Chinese text
Many researchers have spent decades attempting to decode biblical descriptions and link them to verifiable historical events. One such description is that of the Star of Bethlehem—a bright astronomical body that was said ...
Phys.org / Image: JWST captures colliding spiral galaxies
Mid-infrared observations from NASA's James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA's Chandra X-ray Observatory, highlighted in blue. Together, these different wavelengths ...
Phys.org / Are we the Martians? The intriguing idea that life on Earth began on the red planet
How did life begin on Earth? While scientists have theories, they don't yet fully understand the precise chemical steps that led to biology, or when the first primitive life forms appeared.
