Dialog / Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?
Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy. Paradoxically, however, the nature of these dark ...
Phys.org / Classical physics can explain quantum weirdness, study shows
When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that same ball down to the size ...
Phys.org / US climate sees decline in both hot and cold extreme temperatures since 1899, researchers claim
A comprehensive new study extending the U.S. Historical Climatology Network (USHCN) record back to 1899 finds that both hot and cold temperature extremes across the contiguous United States have declined over the past 127 ...
Phys.org / Scraped from ancient Roman toilets, these crusted remains expose a pathogen found far earlier than expected
Modern analytical tools are no less than a time machine. From their 21st-century labs, researchers can peer into the everyday lives, hygiene, and even the parasites that plagued the people who lived centuries ago. In one ...
Phys.org / Why does life prefer one 'hand' over the other? New study points to electron spin
A team of scientists has identified a new physical mechanism that could help explain one of the most persistent mysteries in science: why life consistently uses one "handed" version of its molecules and not the other. In ...
Phys.org / DESI completes planned 3D map of the universe and continues exploring
The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone ...
Tech Xplore / Fusion power may never be cost-competitive with renewables, study warns
Fusion power plants are sites at which electricity could be generated via a process known as nuclear fusion, which entails the merging of two atomic nuclei into a single heavier nucleus. This process is known to generate ...
Phys.org / Clearing crowded supermarket aisles lifts sales by 11.5% in field tests
Additional product displays in supermarket aisles—so-called secondary placements—are intended to encourage impulse purchases. However, a new study by Mathias C. Streicher of the University of Innsbruck shows that excessive ...
Medical Xpress / CDC report on COVID vaccine blocked from publication
A federal report pointing out the benefits of COVID-19 vaccines may never be released, according to multiple people familiar with the decision.
Phys.org / People with dark personality traits are naturally inclined towards leadership roles, finds new study
Can you tell if you're working with a narcissist or a psychopath? A new study suggests that people's job choices may offer some clues, especially in fields built on leadership and persuasion such as business, politics, and ...
Phys.org / Physicists revive 1990s laser concept to propose a next-generation atomic clock
Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized laser, where atoms work in concert rather than independently. Publishing their results in Physical ...
Phys.org / These eight coastal cities sit on America's flood front line, and AI shows why
New York, New Orleans and Miami are among the eight cities along the US Gulf and Atlantic coasts facing the highest flood risk, according to a new study published in Science Advances. Scientists developed a new AI-driven ...
