    Changing Priorities: Bush initiative shifts science-budget funds

    President Bush's proposed fiscal year 2007 budget would keep overall research-and-development (R&D) spending at current levels and shift funds to the three agencies critical to a White House initiative to maintain U.S. leadership in science and technology.

    The $2.77 trillion spending plan includes $137 billion for R&D in 2007. While this number is up more than $3...

    Found: A missing hot halo

    X-ray observations of the massive spiral galaxy NGC 5746 reveal a spherical halo of hot gas (blue) extending 60,000 light-years on either side of the galaxy's visible disk (seen edge on as a large white streak).

    Because NGC 5746, which is 100 million light-years from Earth, doesn't form stars prodigiously or have an energetic core, it's not likely that the halo is gas...

    Low-Fat Diet Falls Short: It's not enough to stop cancers, heart disease

    Reducing fat consumption after menopause offers most women little if any protection against breast cancer or several other diseases, according to three reports from a massive prevention trial. No significant differences in rates of colorectal cancer, heart disease, or stroke emerged during the trial.

    But "little snippets of information" from the Women's Health Initiative (WHI) trial...

    Males as Nannies? First test for wasps' hidden baby-care skills

    If scientists kidnap all adult females from a wasp nest, the young males—which normally just hang around without working—will pitch in and feed at least some of the larvae, researchers find. This shows that male wasps have the wherewithal to do a job.

    The scientists removed female workers from the nests of the southern Indian wasp Ropalidia marginata. The study is the first...

    Combat Trauma from the Past: Data portray Civil War's mental, physical fallout

    Thanks to extensive military and medical records for Union Army veterans of the U.S. Civil War, a research team has determined that soldiers who saw many of their comrades killed or who were prisoners of war experienced a greater incidence of serious physical and mental ailments later in life and died at younger ages than other veterans did.

    The link between harrowing combat...

    Beyond Bar Codes: Tuning up plastic radio labels

    Electronic labels made from plastic semiconductors can now pick up and respond to radio signals at a frequency suitable for use on products. At an electronics conference in San Francisco this week, two European industrial-research teams described plastic radiofrequency-identification (RFID) prototypes with those advanced capabilities.

    Although silicon-based RFID tags are already in wide...

    Ancestor of Kings: Early progenitor of T. rex had a crest

    Paleontologists have unearthed remains of the oldest known dinosaur of the tyrannosaur clan. About 160 million years ago, the agile, 3-meter-long predator roamed what is now northwestern China. Its fossils bolster a recent theory about the evolutionary origins of the fearsome meat eaters that appeared later.

    Dubbed Guanlong wucaii, which in Mandarin means "crowned dragon...

    Chimps creep closer yet

    Chimpanzees may be more closely related to humans than to any other primate, new genetic evidence suggests.

    "We all know that humans and chimps are extremely close genetically," says study coauthor Soojin Yi, an evolutionary biologist at the Georgia Institute of Technology in Atlanta. The two species diverged from a common ancestor from 5 million to 7 million years ago and have 95 to 98...

    Mouth cancer data faked, journal says

    A study claiming to find that anti-inflammatory drugs including ibuprofen reduce the risk of mouth cancer in smokers was based on falsified data, according to the medical journal that published the research.

    Jon Sudbø of the Norwegian Radium Hospital and the University of Oslo presented the findings last year at a cancer-research meeting in Anaheim, Calif. (SN: 5/7/05, p. 302: Available...

    Finding a face place in monkeys' brains

    Monkeys recognize a wide variety of faces thanks to a brain area that specializes in face perception, according to a new study.

    A team led by Doris Y. Tsao of Harvard Medical School in Boston used functional magnetic resonance imaging (fMRI) to identify three particularly face-responsive patches of brain tissue in each of two macaque monkeys. The researchers then implanted electrodes in...
