Phys.org / Fighting poverty may require cultural wisdom, not just cash
Most poverty-fighting efforts focus on meeting basic material needs, such as food and shelter. But this overlooks the psychological and cultural factors that shape how people take action in their lives.
Phys.org / Adaptive tracking theory of molecular evolution challenges mutation neutrality
For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary enough to slip through the ...
Phys.org / Even moderate heat waves can depress sea urchin reproduction along the Pacific coast
Biologists thought that marine heat waves lowered urchin reproduction only at lethal temperatures. A new study shows reproductive shutdown even earlier.
Phys.org / HD⁺ ions cooled to 18 mK yield most precise vibrational-rotational spectra to date
A research team from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of Sciences has made significant progress in precisely measuring the vibrational-rotational spectra ...
Medical Xpress / Inflammasome found to drive male-specific bone loss in gum disease
A study out of the University of North Carolina at Chapel Hill has unveiled new insights into the inflammatory processes behind periodontitis, a common and debilitating gum disease. Research conducted by UNC Adams School ...
Tech Xplore / Porous separators boost efficiency of electrolyzers for carbon monoxide reduction
Electrolyzers, devices that use electricity to drive desired chemical reactions, could enable the production of clean hydrogen (H2) gas from water (H2O) and the conversion of carbon dioxide (CO2) into useful fuels or industrial ...
Phys.org / ALMA resolves close companion orbiting giant red star
Close companions can influence stellar evolution in many ways. While some companions can be detected around young stellar objects, direct observational evidence of companions around asymptotic giant branch (AGB) stars or ...
Phys.org / Fragments of Stone of Scone tracked down to reveal a hidden history
The Stone of Scone, also known as the Stone of Destiny, is a treasured relic of history in Great Britain, used for centuries as an accompaniment to the coronation of kings. This 152 kg (335 lb) sandstone block has suffered ...
