Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33,000 km/h, the winds make up the fastest jet-stream of its kind ever measured on a planet. The discovery provides unique insights into the weather patterns of a distant world.

If you've ever tossed a generous pinch of salt into your pasta pan's water for flavor or as an attempt to make it boil faster, you've likely ended up with a whitish ring of deposits inside the pan. A group of scientists, inspired by this observation during an evening of board games and pasta dinner, wondered what it would take to create the most beautiful salt ring inside the pasta pan they report their findings about what causes these peculiar salt particle cloud deposits to form.

Astronomers previously thought all FRBs were generated by magnetars formed through the explosions of very young, massive stars. But new FRB is pinpointed to the outskirts of 11.3-billion-year-old galaxy without young, active stars -- calling those assumptions into question. 'Just when you think you understand an astrophysical phenomenon, the universe turns around and surprises us,' researcher says.

Instead of relying on energy-hungry reactors to generate high temperatures and pressure, researchers are looking underground at Earth's natural heat and forces to cook up ammonia for fertilizer. In a proof-of-concept study, researchers generated ammonia by mixing nitrogen-laced water with iron-rich rocks -- without any energy input or CO2 emission. This new recipe may lead to a more sustainable alternative to current methods, theoretically churning out enough ammonia for 2.42 million years.

Researchers present paper-based temperature and humidity sensors that are accurate, reliable, and eco-friendly. The team created the sensors by printing silver lines on commercially available paper through dry additive nanomanufacturing. As the paper absorbs water vapor, its capacitance change is measured to reflect the relative humidity of the environment, and as the temperature increases, the metallic conductor experiences an increase in resistivity. They successfully detected changes in relative humidity levels from 20% to 90% and temperature variations from 25 C to 50 C.

The megaflood that refilled the Mediterranean Sea 5 million years ago was so huge and fast that it shaped the landscape of what is now Sicily

From carefully timing meals and bedtime to turning down the lights and banning screens in bed, here's what the scientists who study sleep do to optimise their slumber
