Moon's molten, churning core likely once generated a dynamo
When the Apollo astronauts returned to Earth, they brought with them some souvenirs: rocks, pebbles, and dust from the moon's surface. These lunar samples have since been analyzed for clues to the moon's ...
Fermi satellite finds hints of starquakes in magnetar 'storm'
(Phys.org) —NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing ...
NuSTAR sees rare blurring of black hole light
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the ...
Material generates steam under solar illumination
A new material structure developed at MIT generates steam by soaking up the sun.
Tropical cyclone intensity shifting poleward, study shows
Powerful, destructive tropical cyclones are now reaching their peak intensity farther from the equator and closer to the poles, according to a new study co-authored by an MIT scientist.
Photonic crystal nanolaser biosensor simplifies DNA detection
A simple method to sense DNA, as well as potential biomarker proteins of cancer or other diseases such as Alzheimer's, may soon be within reach - thanks to the work of a team of Yokohama National University ...
Humans erode soil 100 times faster than nature
A new study shows that removing native forest and starting intensive agriculture can accelerate erosion so dramatically that in a few decades as much soil is lost as would naturally occur over thousands of ...
Switching on a dime: How plants function in shade and light
Photosynthesis is the process by which plants convert energy from the sunlight into chemical energy in the form of sugars. These sugars are used by plants to grow and function, as well as food for animals ...
Engineers find a way to win in laser performance by losing
Energy loss in optical systems, such as lasers, is a chief hindrance to their performance and efficiency, and it occurs on an ongoing, frustrating basis.
Studies fault warming in much of 2013 wild weather (Update 2)
Scientists looking at 16 cases of wild weather around the world last year see the fingerprints of man-made global warming on more than half of them.
No excess baggage: Antarctic insect's genome, newly sequenced, is smallest to date
Scientists who sequenced the genome of the Antarctic midge suspect the genome's small size – the smallest in insects described to date – can probably be explained by the midge's adaptation to its extreme ...
Researcher part of team studying ways to better predict intensity of hurricanes
They are something we take very seriously in Florida – hurricanes. The names roll off the tongue like a list of villains – Andrew, Charlie, Frances and Wilma.
Arctic study sheds light on tree-ring divergence problem
Changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees' growth, according to a new study by San Francisco State University researcher Alexander Stine.
Swimming ants don shades to save their eyesight
Australia's unusual swimming ants take their own 'sunglasses' when they go to the beach – to shield their sensitive eyes from bright sunlight.
