Arctic river ice deposits rapidly disappearing

Ecology
WASHINGTON, DC — Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds. River icings form when Arctic groundwater reaches the surface and solidifies on top of frozen rivers. They grow throughout ...

Air pollution may directly cause those year-round runny noses, according ...

Medicine
Although human population studies have linked air pollution to chronic inflammation of nasal and sinus tissues, direct biological and molecular evidence for cause and effect has been scant. Now, Johns Hopkins researchers report that experiments in mice continually exposed to dirty air have revealed that direct biological effect. Researchers have ...

Creating time crystals

Physics
Harvard physicists have created a new form of matter – dubbed a time crystal – which could offer important insights into the mysterious behavior of quantum systems. Traditionally speaking, crystals – like salt, sugar or even diamonds – are simply periodic arrangements of atoms in a three-dimensional lattice. Time crystals, ...

The world’s most spoken language is…’Terpene’

Biology
If you’re small, smells are a good way to stand out. A team of researchers led by the Netherlands Institute of Ecology (NIOO-KNAW) has demonstrated for the first time that two different types of micro-organisms — bacteria and fungi — use fragrances, known as terpenes, to hold conversations. And that’s ...

Hubble spots auroras on Uranus

AstronomyMore Science
Ever since Voyager 2 beamed home spectacular images of the planets in the 1980s, planet-lovers have been hooked on auroras on other planets. Auroras are caused by streams of charged particles like electrons that come from various origins such as solar winds, the planetary ionosphere, and moon volcanism. They become ...
