When a spent rocket booster slammed into the frigid, inky shadow of a lunar crater last month, it sent up a slightly damp plume of dust, scientists with NASA's Lunar Crater Observation and Sensing Satellite mission reported last week.
Attempting to rein in Japan's yawning budget deficit, a government task force last week recommended tens of millions of dollars in cuts in science spending in the fiscal year beginning next April that would hit everything from research grants to big-ticket items such as a next-generation supercomputer.
Two new astronomical results—one in this week's issue of Science and the other published online this month in Nature—suggest that cosmic rays acquire their tremendous velocities from exploding stars.
World production of conventional oil is likely to peak before 2030 and could reach its limits before 2020, a major report from a new voice in the debate over oil depletion warns. In view of the daunting task of weaning the world's transportation off oil, the risk of a peak before 2030 "needs to be given serious consideration," the report says.
Within a couple of years, a scientific team hopes to start clinical trials using cells from the first swine herd in the country specially bred to supply insulin-secreting pancreatic islets for people with diabetes. But they face immunological and regulatory challenges, as well as the challenge of overcoming public aversion to the idea.
ScienceNOW this week reported that meditation halves the risk of heart disease, empathy is in our genes, holes can block light, and new neurons make room for new memories, among other stories.
In an interview with Science, Zhu Qingshi, the newly appointed president of China's planned South University of Science and Technology, explained how he intends to shake up China's university system—whether the education ministry likes it or not.
More than a half-dozen major U.S. universities and institutes pledged last week to lean on biotech companies when licensing intellectual property to secure more favorable terms for countries in the developing world.
ScienceInsider reported this week that the American Physical Society's governing council has rejected a petition to revise a 2007 statement on global warming and Brazil has announced a plan to cut carbon emissions between 36% and 39% by 2020, among other stories.
The oil of the future—vast and largely untapped reserves of petroleum in the form of tarry deposits a few tens of meters beneath the surface—has serious reclamation challenges right now.
Researchers have long debated whether the highly carnivorous Neandertals sometimes ate each other. In recent years, new evidence for this macabre hypothesis has emerged.
Chloroplasts seem to rely on the polymerization of protein filaments to make their way across a cell, researchers reported at the 9th International Plant Molecular Biology Congress, and they can move quickly—or slowly—depending on the circumstances.
At the 9th International Plant Molecular Biology Congress, researchers described progress in manipulating the beta-glucan content of grains and other plant tissues, which could boost the fiber content of foods and enhance the value of the currently unusable parts of corn and wheat for biofuels.
Researchers have proposed that genes that code for proteins that are part of complexes are most likely to survive the purging that follows whole-genome duplications. Increasing evidence from the 9th International Plant Molecular Biology Congress and other meetings suggests that this so-called gene balance hypothesis may be correct.
Surveying and evaluating the scientific literature gender disparities in mathematics, science, and engineering disciplines, Ceci and Williams argue that the underrepresentation of women in these fields is due to "certain choices that women (but not men) are compelled to make in our society."
Declines in North American megafauna populations began before the Clovis period and were the cause, not the result, of vegetation changes and increased fires.
Genes involved in metal tolerance likely played a role in maize domestication.
