(Phys.org) —Russian physicists Alex Gurevich and Anatoly Karashtin claim, in a paper published in the journal Physical Review Letters, they have found more evidence to support their idea that lightning is caused by cosmic ...
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don't look much like those perfect-but-rare snowflakes often seen ...

(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...
One might expect water to evaporate much faster than ice. Surprisingly, researchers from the University of Amsterdam have now shown that for small droplets of ice, this is not the case: ice and water droplets disappear equally ...
