Antarctica's retreating ice may re-shape Earth
(AP)—From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can't be seen is the battle raging underfoot to re-shape Earth.
Monster black hole discovered at cosmic dawn
Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time. The international team led by astronomers from Peking University in China ...
Physicists offer a solution to the puzzle of the origin of matter in the universe
Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very small degree, ...
Life 'not as we know it' possible on Saturn's moon Titan
A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled by a team of Cornell University researchers.
Interaction of Atlantic and Pacific oscillations caused 'false pause' in warming
The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate ...
Study seeks to understand variations in the rate of global warming
A team of climate scientists, including Professor Mat Collins from the University of Exeter, have investigated the role of internal variability in the Earth's climate system in these periods of slow warming.
Distant quasar spectrum reveals no sign of changes in mass ratio of proton and electron over 12 billion years
Sea level spiked for 2 years along northeastern North America
Sea levels from New York to Newfoundland jumped up about four inches in 2009 and 2010 because ocean circulation changed, a University of Arizona-led team reports in an upcoming issue of Nature Communications.
Could there be another planet behind the sun?
If you've read your share of sci-fi, and I know you have, you've read stories about another Earth-sized planet orbiting on the other side of the Solar System, blocked by the Sun. Could it really be there?
Earth's other 'moon' and its crazy orbit could reveal mysteries of the solar system
We all know and love the moon. We're so assured that we only have one that we don't even give it a specific name. It is the brightest object in the night sky, and amateur astronomers take great delight in ...
Electric-car driving range and emissions depend on where you live
Many car buyers weighing whether they should go all electric to help the planet have at least one new factor to consider before making the switch: geography. Based on a study of a commercially available electric ...
Several "new" craters found in Siberia
The Curiosity robot confirms methane in Mars' atmosphere which may hint that existed life
The tunable laser spectrometer in the SAM (Sample Analysis at Mars) instrument of the Curiosity robot has unequivocally detected an episodic increase in the concentration of methane in Mars' atmosphere after ...
Behaviour study shows rats know how to repay kindness
If I scratch your back and you scratch mine, then we're both better off as a result – so goes the principle of reciprocity, one of the most popular explanations for how co-operative behaviour has evolved. ...
