Scientists to Io: Your volcanoes are in the wrong place
(Phys.org) —Jupiter's moon Io is the most volcanically active world in the Solar System, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high. However, concentrations of volcanic ...
Mercury may have harbored an ancient magma ocean, paper reveals
By analyzing Mercury's rocky surface, scientists have been able to partially reconstruct the planet's history over billions of years. Now, drawing upon the chemical composition of rock features on the planet's ...
Clear link between solar activity and winter weather revealed
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
Suddenly, the sun is eerily quiet: Where did the sunspots go?
The sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum-the time in the sun's 11-year cycle when ...
Missing sunspots: Solar mystery solved
The Sun has been in the news a lot lately because it's beginning to send out more flares and solar storms. Its recent turmoil is particularly newsworthy because the Sun was very quiet for an unusually long ...

New path to flex and stretch electronics: Researchers develop solution-based fabrication technique
(PhysOrg.com) -- Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make "smart devices" nearly ubiquitous. Among the ...
A Puzzling Collapse of Earth's Upper Atmosphere
NASA-funded researchers are monitoring a big event in our planet's atmosphere. High above Earth's surface where the atmosphere meets space, a rarefied layer of gas called "the thermosphere" recently collapsed ...

Dire outlook despite global warming 'pause': study
A global warming "pause" over the past decade may invalidate the harshest climate change predictions for the next 50 to 100 years, a study said Sunday—though levels remain in the danger zone.
Jupiter has lost one of its cloud stripes
Solar activity playing a minimal role in global warming, research suggests
Changes in solar activity have contributed no more than 10 per cent to global warming in the twentieth century, a new study has found.
