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 ...
Material generates steam under solar illumination
A new material structure developed at MIT generates steam by soaking up the sun.
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 ...
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.
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.
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 ...
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 ...
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.
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.
Comet ISON unfolds its wings
(Phys.org) —One or more fragments may have detached from comet ISON in the past days, as two wing-shaped features in the comet's atmosphere suggest. Scientists from the Max Planck Institute for Solar System ...
Hidden details revealed in nearby starburst galaxy
Using the new, high-frequency capabilities of the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT), astronomers have captured never-before-seen details of the nearby starburst galaxy ...
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.
