Phys.org / 8.2 ka event triggered social transformation, not destruction, at China's Jiahu site
In a recent study, Dr. Yunchen Tan and colleagues examined the response of the North China Plain settlement of Jiahu to the abrupt climatic 8.2 ka event. They found that Jiahu not only survived but also demonstrated remarkable ...
Phys.org / Dark matter hiding in stars may cause observable oscillations
(Phys.org)—Dark matter has never been seen directly, but scientists know that something massive is out there due to its gravitational effects on visible matter. One explanation for how such a large amount of mass appears ...
Medical Xpress / The price of persuasion: Why vaccine messaging may deepen social divides
Encouraging people to get vaccinated is often seen as a public health success story. However, understanding how persuading people to roll up their sleeves to receive vaccines creates social division is crucial—particularly ...
Phys.org / Death by Design? Spatial models show that natural selection favors genetically-limited lifespan as a lineal benefit
(Phys.org)—Standard evolutionary theories of aging and mortality, being based on mean-field assumptions – which analyze the behavior of large and complex stochastic models by studying a simpler model – conclude that ...
Medical Xpress / Biophobia: Why some people hate nature—and what you can do about it
We're constantly told that spending time in nature is good for the body and the mind alike. A large body of research shows multiple health benefits from contact with nature, ranging from stress reduction to an improved immune ...
Medical Xpress / What to do if you fail at your New Year's resolution
Every year, many of us bravely announce our resolutions for the new year. A glass of champagne on New Year's Eve might add to our confidence in our ability to do better in the coming year and save more, spend less, eat better, ...
Phys.org / High-energy photons drive conversion of greenhouse gases into high-value chemicals, no catalyst needed
Scientists have found a way to turn carbon dioxide and methane, the two most notorious greenhouse gases, into useful chemicals without any expensive catalysts, using only light.
Medical Xpress / Pediatrician explains why bullying hurts all children and what parents can do about it
Every day, thousands of kids suffer the fear, shame and frustration of being bullied. More than 19% of children aged 12 to 18 say they have been targeted by peers, with a frightening number of cases happening online. A pediatrician ...
Phys.org / Alloy engineering addresses long-standing problem of semiconductor defects
(Phys.org)—The performance of all of today's electronic devices depends on the quality of the semiconductor materials they're made of. Two of the most important factors that affect a semiconductor's properties are its band ...
Phys.org / Scientists propose 3D graphene-like 'hyper-honeycomb' structures
(Phys.org)—Scientists have proposed a new family of structures that are three-dimensional (3D) variations of graphene, the simplest example of which is called a "hyper-honeycomb." If the proposed structures can be experimentally ...
Phys.org / Cypriot fishermen battle invasive lionfish and turn them into a tavern delicacy
Photis Gaitanos' rough fingers adroitly untangle the venomous spikes of a lionfish from a net, throwing the exotic-looking creature into an ice-filled rubber bin along with other fish from the day's catch.
Phys.org / Proposed diamond maser could operate at room temperature
(Phys.org)—Before there were lasers, there were masers—devices that operate in the microwave regime and other wavelengths that are longer than those of visible light. But while the first masers were built back in the ...
