Phys.org / Disentangling the many factors at play within exposure science
Take a brief walk outside and you're likely to encounter a wide range of things that could influence your health—the sunlight beaming on your face, a plume of exhaust, or even noise from a car driving by. Each exposure carries ...
Science X / Snowball Earth may hide a far stranger climate cycle than anyone expected
During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In Snowball Earth models, the ...
Phys.org / A physics explanation shows why US elections keep ending 50:50—and why more spending won't change that
A physics-inspired model calibrated on 40 years of US congressional data pinpoints a spending threshold of roughly 1.8 million USD at which campaigns stop influencing who wins and start fueling polarization instead.
Phys.org / Sudden quantum jolts may not break adiabatic behavior after all
In thermodynamics, an "adiabatic process" is a system change that transfers no heat in or out of the system. Any and all energy change in that system are therefore accomplished by doing work on the system, work being action ...
Phys.org / Physicists reveal universal speed limit on quantum information scrambling
Theoretical physicists in the US have discovered a "speed limit" on the time taken for quantum information to spread through larger systems. Publishing their results in Physical Review Letters, Amit Vikram and colleagues ...
Science X / Your hand betrays your sense of fairness, and it does so before you even realize it
It turns out that your body is much more truthful about what is and isn't fair than you might imagine. The rate at which we make physical movements is able to reveal whether our motives are self-interested or retaliatory.
Medical Xpress / Diabetes flips immune cells from repair to inflammation in peripheral artery disease, study finds
Type 2 diabetes can turn immune cells that help with tissue repair and anti-inflammatory responses into triggers of chronic inflammation. A recent study investigated why people with type 2 diabetes are at a higher risk of ...
Phys.org / An interplanetary shortcut can speed up trips to Mars
Whether it's robotic rovers heading to Mars or, one day, a crew of astronauts, a round-trip journey is an incredibly long one. But there may be a way to find a shortcut. A new study published in the journal Acta Astronautica ...
Phys.org / Canada proposes POET mission to hunt Earth-sized planets
Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets being designated as ...
Phys.org / How temperature swings impact the growth of young songbirds
Climate change threatens to cause increasingly extreme and variable temperature swings, affecting everything from urban infrastructure to global food supplies. In the animal kingdom, the hardest hit may be the youngest and ...
Phys.org / Levitated nano-ferromagnet confirms a 160-year-old physical prediction
Ferromagnets, such as iron, cobalt, and nickel, are materials with a strong, spontaneous, and permanent magnetic field. Over 150 years ago, the physicist and mathematician James Clerk Maxwell speculated that under specific ...
Phys.org / Room-temperature multiferroic could pave way to low-energy computing
A team of researchers at Rice University has engineered a new version of a well-known multiferroic that exhibits orders of magnitude higher performance at room temperature than its parent material. The study, published in ...
