Simulations show Eurasia more than twice as likely to have harsh winters due to sea ice melting
Marks on Martian dunes may be tracks of dry-ice sleds
(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
Fossil palm beetles 'hindcast' 50-million-year-old winters

Light switches brain signaling: Longer days bring 'winter blues' for rats
Most of us are familiar with the "winter blues," the depression-like symptoms known as "seasonal affective disorder," or SAD, that occurs when the shorter days of winter limit our exposure to natural light ...
Chasing the black holes of the ocean
According to researchers from ETH Zurich and the University of Miami, some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly ...
Physics professor finds old Roman fort in England aligned with the sun
Study of electrons in space could help weather forecasting
Researchers have discovered a formerly undetected impact of space weather on the polar atmosphere, which may explain some previously unexplained variations in winter weather patterns. Their results, published today (Tuesday ...
Winters in Siberian permafrost regions have warmed since millenia
For the first time, researchers at the Alfred Wegener Institute have successfully decoded climate data from old permafrost ground ice and reconstructed the development of winter temperatures in Russia's Lena ...
Opportunity rover rolling again after fifth Mars winter

Bright eyes: Study finds reindeers' eyes change colour with Arctic seasons
Researchers have discovered the eyes of Arctic reindeer change colour through the seasons from gold to blue, adapting to extreme changes of light levels in their environment and helping detect predators.
Link found between cold European winters and solar activity
Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Yet records of average, seasonal temperatures do not date back far enough to confirm any patterns. ...
