Phys.org / Why is almost everyone right-handed? The answer may lie in how we learned to walk
It is one of the strangest puzzles in human evolution. About 90% of people across every human culture favor their right hand—with no other primate species showing a population-level preference on this scale. Despite decades ...
Medical Xpress / Benefits of using a Bayesian statistical framework for replicating research
The "replication crisis" refers to a problem in the sciences where findings from previous experiments don't hold up when studies are repeated. It is a particular issue for those in the behavioral sciences and experimental ...
Phys.org / How a 4,000-year-old city defied history's 'rules' by becoming more equal as it became more successful
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control ...
Phys.org / Q&A: Is it time to expand our thinking about dark matter? A new study says yes
We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature of black holes and dark ...
Medical Xpress / Sleep disturbances during pregnancy associated with a risk of gestational diabetes
A study by Kuopio University Hospital and the University of Eastern Finland shows that sleep disturbances during pregnancy may be a significant risk factor for gestational diabetes mellitus (GDM).
Phys.org / String theory is uniquely derived from basic assumptions about the universe, physicists show
If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up. You might think you hit ...
Phys.org / Rare seals hide in underwater bubble caves to escape tourists
The uninhabited islet of Formicula in Greece's Inner Ionian archipelago is a popular tourist draw for its clear waters, swimming spots, and marine diversity. A major attraction is the Mediterranean monk seal, one of the world's ...
Medical Xpress / Written in the eye: How the retina's biological age could help predict osteoporosis risk
Eyes, the high-resolution biological devices that help us visualize the outside world, are now being used as a portal to assess our internal health. Scientists have found that a closer evaluation of how one's retina is aging ...
Phys.org / Webb discovers one of the universe's first galaxies
Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe's first stars and is one of the most chemically primitive galaxies observed ...
Phys.org / Less low cloud cover lets in more heat from the sun—and may lock in centuries of sea level rise
According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems around the world.
Phys.org / Consistency check casts doubt on evolving dark energy
Cosmologists have long struggled to determine whether the universe's accelerating expansion is being driven by a simple cosmological constant, or whether dark energy's influence is evolving over time. In a new analysis published ...
Tech Xplore / Scientists develop near-invisible solar cells that could turn windows into power generators
Imagine a car whose windows and sunroof can help top up its battery while parked under the sun, or a pair of smart glasses whose lenses can harvest light to power built-in electronics.
