News of the Week
In science news around the world this week, the first of the Giant Magellan Telescope's seven mirrors has been cast, Australian scientists are once again being awarded grants, the United Kingdom is fighting a fungal disease that threatens its ash woodlands, European researchers are petitioning their heads of state in an effort to prevent budget cuts, and a new report says the U.S. Department of Defense should consider hiring foreign-born scientists.
A coalition of science groups received answers from nine lawmakers on science and science policy questions that it sent to Republican and Democratic congressional leaders. Researchers also created what may be the first image of the blood-brain barrier in a live animal. They gave a zebrafish embryo a gene for a protein that glows red in the barrier's endothelial cells and color-coded the blood vessels. In other news, dozens of apps and gadgets that claim to repel mosquitoes with high-frequency sounds are endangering the public, and some scientists are fed up.
This week's Newsmakers are Chi-Chang Kao, an x-ray physicist at SLAC National Accelerator Laboratory who is SLAC's new director, and Mark Ferguson, the head of Science Foundation Ireland who is now also Ireland's chief scientific adviser.
News & Analysis
Italy's government lacks experts to advise it on natural hazards following the conviction last week of six scientists and a government official for advice they gave ahead of the deadly earthquake in L'Aquila in 2009.
A cell's defensive reaction to viruses seems to make it more open to expressing genes that are usually shut down—whether they are those that trigger inflammation or those that are active in stem cells.
At a meeting of vertebrate paleontologists last month, researchers pondered fresh clues about the origins of flight from studies of feathered dinosaurs and baby birds.
Indonesian children lag far behind their peers on global measures of science aptitude. But rather than use that poor performance as a call to arms, the Indonesian government wants to eliminate science as a subject in the nation's elementary schools.
Researchers argue that most work on Myc, a gene linked to aggressive cancers, needs to be reevaluated. They say that Myc's cancerous effects are actually much broader, and that a flawed experimental method may have thrown off previous research.
An investigation and a congressional hearing earlier this year prompted the Office of Management and Budget to impose government-wide restrictions on conference travel—and now some scientific meetings are paying the price.

Mesostructured alumina acts as an insulating scaffold for the assembly of very thin films of n- and p-type semiconductors.
Isotopic dating implies that, contrary to previous results, two types of primitive solar system solids formed coevally.
