Science is the academic journal of the American Association for the Advancement of Science and is one of the world's top scientific journals. The peer-reviewed journal, first published in 1880, is circulated weekly and has a print subscriber base of around 130,000. Because institutional subscriptions and online access serve a larger audience, its estimated readership is one million people. The major focus of the journal is publishing important original scientific research and research reviews, but Science also publishes science-related news, opinions on science policy and other matters of interest to scientists and others who are concerned with the wide implications of science and technology. Unlike most scientific journals, which focus on a specific field, Science and its rival Nature cover the full range of scientific disciplines. Science's impact factor for 2010 was 31.364 (as measured by the Institute for Scientific Information).
Wet paleoclimate of Mars revealed by ancient lakes at Gale Crater
We have heard the Mars exploration mantra for more than a decade: follow the water. In a new paper published October 9, 2015, in the journal Science, the Mars Science Laboratory (MSL) team presents recent results of its quest ...
Scientists find formula for rate of glacial erosion
It's a truism that mathematical relationships are present nearly everywhere in nature, probably more than we realise. The latest place they have turned up is on the underside of glaciers.
Ancient genome from Africa sequenced for the first time
The first ancient human genome from Africa to be sequenced has revealed that a wave of migration back into Africa from Western Eurasia around 3,000 years ago was up to twice as significant as previously thought, and affected ...
From a very old skeleton, new insights on ancient migrations
Three years ago, a group of researchers found a cave in Ethiopia with a secret: it held the 4,500-year-old remains of a man, with his head resting on a rock pillow, his hands folded under his face, and stone flake tools surrounding ...
New method facilitates research on fuel cell catalysts
While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Therefore, catalyst ...
Plant biosensor could help African farmers fight parasitic 'witchweed'
Engineering and biology professors at the University of Toronto have developed a new strategy for helping African farmers fight a parasitic plant that devastates crops.
Math story time at home bolsters achievement in school
Adding math talk to story time at home is a winning equation for children's math achievement, according to new research from the University of Chicago.
Researchers create inside-out plants to watch how cellulose forms
Researchers have been able to watch the interior cells of a plant synthesize cellulose for the first time by tricking the cells into growing on the plant's surface.
Scientists discover essential amino acid sensor in key growth-regulating metabolic pathway
Whitehead Institute scientists have at last answered the long-standing question of how the growth-regulating pathway known as mechanistic target of rapamycin complex 1 (mTORC1) detects the presence of the amino acid leucine—itself ...
New polymer creates safer fuels
Before embarking on a transcontinental journey, jet airplanes fill up with tens of thousands of gallons of fuel. In the event of a crash, such large quantities of fuel increase the severity of an explosion upon impact. Researchers ...
