Medical Xpress / Subsidizing insurance just props up dysfunction: Empower consumers instead
Congress ended its impasse to reopen the government, but the Democrats' reason for the shutdown remains unresolved: the renewal of expiring subsidies for insurance premiums under the Affordable Care Act.
Medical Xpress / Air pollution may reduce health benefits of exercise
Long-term exposure to toxic air can substantially weaken the health benefits of regular exercise, suggests a new study by an international team including UCL (University College London) researchers.
Phys.org / After nearly 100 years, scientists may have detected dark matter
In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies ...
Phys.org / Yes, the universe can expand faster than light
An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel from them over to here, ...
Phys.org / Is the universe Infinite?
The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond our observable horizon.
Phys.org / Consciousness as the foundation: New theory addresses nature of reality
Consciousness is fundamental; only thereafter do time, space and matter arise. This is the starting point for a new theoretical model of the nature of reality, presented by Maria Strømme, Professor of Materials Science at ...
Phys.org / Examining why some species developed consciousness while others remained non-conscious
What is the evolutionary advantage of our consciousness? And what can we learn about this from observing birds? Researchers at Ruhr University Bochum published two articles on this topic.
Phys.org / Ambitious plan to store CO₂ beneath the North Sea set to start operations
Appearing first as a dot on the horizon, the remote Nini oil field on Europe's rugged North Sea slowly comes into view from a helicopter.
Phys.org / Scientists warn mountain climate change is accelerating faster than predicted, putting billions of people at risk
Mountains worldwide are experiencing climate change more intensely than lowland areas, with potentially devastating consequences for billions of people who live in and/or depend on these regions, according to a major global ...
Phys.org / Electric vehicle owners face new pay-per-mile tax. What could be the environmental costs?
Modern electric vehicles are transforming the roads with low noise, rapid acceleration and zero exhaust emissions. However, drivers of electric vehicles in the UK will now face a new 3p per mile charge and drivers of hybrid ...
Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Phys.org / Physicist delineates limits on the precision of quantum thermal machines
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...
