The Universe’s first magnetic fields were shockingly weak, but changed everything

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the cosmic web, then validated the results with observations. Their study sets a stricter upper limit on the fields’ strength, aligning with other data and suggesting important consequences for early star and galaxy formation.

Harvard’s salt trick could turn billions of tons of hair into eco-friendly materials

Scientists at Harvard have discovered how salts like lithium bromide break down tough proteins such as keratin—not by attacking the proteins directly, but by altering the surrounding water structure. This breakthrough opens the door to a cleaner, more sustainable way to recycle wool, feathers, and hair into valuable materials, potentially replacing plastics and fueling new industries.

Computer models show clear advantages in new types of wind turbines

Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction.

Dual approach needed to save sinking cities and bleaching corals

Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them time in their fight against sea-level rise, ocean acidification and warming temperatures, a study by scientists suggests. In all but extreme situations, these interventions significantly buffer the impacts of climate change and can buy sinking cities and bleaching corals time to adapt until the beneficial impacts of global emissions reductions kick in.

Costs of natural disasters are increasing at the high end

While the economic cost of natural disasters has not increased much on average, averages can be deceptive. The costs of major disasters like hurricanes Katrina, Maria and Dorian or the massive tornado swarms in the Midwest have increased to a disproportionately larger extent than those of lesser events, and these major disasters have become far more expensive, according to an international team of researchers.
