Checking China’s pollution by satellite
Air pollution has smothered China's cities in recent decades. In response, the Chinese government has implemented measures to clean up its skies. But are those policies effective? Now an innovative study co-authored by an MIT scholar shows that one of China's key antipollution laws is indeed working - but unevenly, with one particular set of polluters most readily adapting to it.

Why ’Find your passion!’ may be bad advice
The belief that interests arrive fully formed and must simply be "found" can lead people to limit their pursuit of new fields and give up when they encounter challenges, according to a new Stanford study. A new study by Stanford psychologists examines the hidden implications of the advice to " find your passion.

The True Power of the Solar Wind
The True Power of the Solar Wind
Electrically charged particles from the sun strike moons and planets with great force. The consequences of these impacts can now be explained by scientists from TU Wien. The planets and moons of our solar system are continuously being bombarded by particles hurled away from the sun. On Earth this has hardly any effect, apart from the fascinating northern lights, because the dense atmosphere and the magnetic field of the Earth protect us from these solar wind particles.

Discovery in the sky with nanodiamonds
A faint and mysterious stream of microwaves emanating from star systems far out in the Milky Way could be caused by tiny diamonds, new research has suggested. For decades scientists have been able to measure this ‘glow' of microwave light, dubbed the anomalous microwave emission (AME), coming from a number of regions in the night sky, but have yet to identify its exact source.

From Moon Rocks to Space Dust: Berkeley Lab's Extraterrestrial Research
From Moon Rocks to Space Dust: Berkeley Lab’s Extraterrestrial Research
From moon rocks to meteorites, and from space dust to a dinosaur-destroying impact, the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has a well-storied expertise in exploring samples of extraterrestrial origin. This research - which has helped us to understand the makeup and origins of objects within and beyond our solar system - stems from the Lab's long-standing core capabilities and credentials in structural and chemical analyses and measurement at the microscale and nanoscale.

3 Questions: Roger Summons on finding organic matter on Mars
3 Questions: Roger Summons on finding organic matter on Mars
NASA's Curiosity rover has found evidence of complex organic matter preserved in the topmost layers of the Martian surface, scientists report today in the journal Science . While the new results are far from a confirmation of life on Mars, scientists believe they support earlier hypotheses that the Red Planet was once clement and habitable for microbial life.

Changes in Earth’s orbit could explain rise and fall of ancient species
Using fossils, researchers found evidence that changes in Earth's orbit and axis of rotation caused changes in evolution, extinction rates of of ancient plankton. New research published in Proceedings of the National Academy of Sciences looks back 450 million years to reveal an important link between changes in our planet's motion through space, and the extinction and evolution of life on Earth.

Collisions of Dead Stars Spray Heavy Elements Throughout Small Galaxies
Collisions of Dead Stars Spray Heavy Elements Throughout Small Galaxies
Caltech scientists have found, for the first time, that merging pairs of neutron stars-the burnt-out cores of stars that have exploded-create the majority of heavy elements in small "dwarf" galaxies. Heavy elements, such as silver and gold, are key for planet formation and even life itself. By studying these dwarf galaxies, the researchers hope to learn more about the primary sources of heavy elements for the whole universe.  The origin of the majority of the heaviest elements of the periodic table, including 95 percent of all gold on Earth, has been debated for decades.

Magnetic field collisions around Saturn reveal planetary differences
Magnetic field collisions around Saturn reveal planetary differences
Magnetic reconnection - the explosive reconfiguration of two magnetic fields - occurs differently around Saturn than around Earth, according to new findings from the international Cassini mission involving UCL researchers. On Earth, the collisions which create aurora are only seen on the boundary between Earth's magnetic field and the magnetic field in interplanetary space.

Does Some Dark Matter Carry an Electric Charge?
Does Some Dark Matter Carry an Electric Charge?
Astronomers have proposed a new model for the invisible material that makes up most of the matter in the Universe. They have studied whether a fraction of dark matter particles may have a tiny electrical charge. "You've heard of electric cars and e-books, but now we are talking about electric dark matter," said Julian Munoz of Harvard University in Cambridge, Mass., who led the study that has been published in the journal Nature .
