Why are some mammals monogamous? Two definitive studies not so definitive.One says some mammals are monogamous to prevent infanticide. The other says they are monogamous because females are spread too widely for males to have multiple mates.
- Giant mushroom found in China
Giant mushroom: This fungus has not yet been identified. But it's not big enough to dislodge Oregon's giant honey mushroom as the largest in the world.
Why the return of the wolf is good news for the bearNew research shows that the reintroduction of wolves to Yellowstone National Park has brought a berry boon to bears, a find that suggests the far-flung, often unexpected impacts a top predator can have on its ecosystem.
NASA asks for help lassoing an asteroid, gets flooded with repliesNASA is reviewing public proposals for how to handle a hypothetical asteroid bound for impact with Earth.
Earthquakes: Another source of global-warming gas, scientists sayA team of scientists has linked a major earthquake in southwest Asia in 1945 to the ongoing release of methane gas from the Arabian seafloor.
Perseid meteor shower: Coming soon to a sky near youPerseid meteor shower: Beloved by skywatchers, 2013 will be an excellent one for the Perseid meteor shower. The moon will set before midnight on the peak Perseids nights.
New lake at North Pole? More of a pond, reallyIs the buzz warranted over a new "lake" at the North Pole thanks to global warming? Mostly no. But the Arctic ice is melting.
- Mysterious hum: The hunt for a source
Mysterious hum: Since the 1950s, people from various towns around the world have heard a mysterious, annoying, low-frequency humming. Research is underway to find the cause (or causes) of "the Hum."
Scientists implant false memories in miceResearchers at the Massachusetts Institute of Technology have found a way to fool mice into remembering an electric shock where none actually existed.
What is a space 'Centaur'? Scientists now know the answerScientists have found the answer to a long-vexing question: what are those strange orbiting objects out past Jupiter?
New IRIS telescope sends stunning images of sun to befuddled scientistsThe IRIS solar observatory, launched last month, has sent back new pictures that show a key part of the sun's atmosphere in unprecedented detail. Some of the data are surprising.

Scientists credited the feat to good visibility. Longer trips like this may become more common when the vehicle switches to automatic navigation in a couple weeks.
Arctic ice melt could cost an extra $60 trillion, say researchersMethane gas released from the melting Arctic ice could accelerate global warming and tack on an extra $60 trillion to the cost the world is expected to incur from climate change.
When Mars was wet: How snow melt might have carved valleysResearchers say that 3.7 billion years ago on Mars, mountain precipitation could have carved networks of wide, shallow valleys that drop from ridges, peaks, and crater rims.
