      High-Energy Physics:

      Deep Potholes Block the Road to Discovery for U.S. Science

      Adrian Cho

      When the Department of Energy (DOE) decided last week to shut down the atomsmasher at the last dedicated U.S. particle physics lab this fall, some scientists breathed a sigh of relief because the move opens the way to pursue a variety of new projects. But U.S. particle physicists still face abumpy ride along an uncertain road. It wasn't long ago that U.S. particle physicists formulated a broad, coherent, and realistic road map to carry the field through the next decade. But that program has now been hit with bureaucratic snags, delays, and unexpected expenses. Some observers even wonder whether DOE, which embraced the plan for its $810-million-a-year high-energy physics program, is capable of implementing it.

      Food Safety:

      Food Safety Law Will Likely Strain FDA Science

      Erik Stokstad

      Contaminated food kills more than 3000 people each year in the United States and sickens more than 48 million, and recalls can cost the food industry many millions of dollars. A major food safety bill signed into lawthis month gives the U.S. Food and Drug Administration new powers and aims to shift the focus from response to prevention of food-borne illness.

      From Science's Online Daily News Site

      ScienceNOW reported recently that pandas prefer old-growth forests, the European Planck satellite has released a catalog of stellar hatcheries,flipper bands harm penguins, and the black hole in the core of galaxy M87 is the most massive black hole for which a precise mass has ever been measured, among other stories.

      ESP Paper Rekindles Discussion About Statistics

      Greg Miller

      A paper in press at a top psychology journal argues that the results of nine experiments conducted with more than 1000 college students provide statistically significant evidence of an ability to predict future events. Not surprisingly, the news has provoked outrage from pseudoscience debunkers and counteraccusations of closed-mindedness from those willing toconsider the possibility of psychic powers. It has also rekindled a long-running debate about whether the statistical tools commonly used in psychology—and most other areas of science—too often lead researchers astray.

      Scientific Publishing:

      Open Access Gains Support; Fees and Journal Quality Deter Submissions

      Gretchen Vogel

      Scientists love open-access papers as readers, but they are less enthusiastic about submitting their papers to open-access journals, according to a new study. The European Union–sponsored Study of Open Access Publishing surveyed 50,000 researchers last year for their opinions on open-access journals, which make all their papers freely available online and usually charge authors a fee for each published paper. The studyfound overwhelming support for the concept, but overall only about 10% of papers are published in open-access journals.

      From the Science Policy Blog

      ScienceInsider reported this week that former E.U. research chief Achilleas Mitsos has resigned as head of research and technology within theGreek education ministry, among other stories.

      Marine Biology:

      Killer Whales Earn Their Name

      Virginia Morell

      Scientists are rethinking the role and effect of killer whales in marine communities, including the possible threat they pose to some of their endangered cetacean cousins. Researchers are now recording killer whale attacks on several species of great whales, as well as seals, narwhals, sealions, walruses, and even penguins. From Russia's Chukotka Peninsula to South Africa's coastal waters to the icy seas of Antarctica—even in Canada's Hudson's Bay, where they had rarely been seen before—scientists are finding mammal-eating killer whales on the prowl.

      Scrambling to Close the Isotope Gap

      Robert F. Service

      Two reactors, one in the Netherlands and the other in Canada, produce 60% of the world's radioactive molybdenum-99, which decays into technetium-99, a radioisotope used in more than 30 million procedures a year worldwide forimaging everything from blood flow through the heart to bone cancer—and both reactors are decades beyond their intended life expectancy. The situation isn't just a problem for doctors and patients. Governments around the world are working to phase out civilian uses of the technology to produce nearly all Mo-99 today because of concerns that the highly radioactive material used in the process could be diverted to make nuclear weapons. And finding replacement technologies to produce the Mo-99,and companies willing to take the financial risk of generating it, is proving challenging.

      Nuclear Medicine:

      A Field Back in Vogue

      Robert F. Service

      In the wake of the nuclear accidents at Three Mile Island in Pennsylvania in 1979 and Chornobyl in 1986, students shunned nuclear sciences, and the United States has struggled ever since to train enough nuclear engineers, radiochemists, and medical physicists to keep the field healthy. To combat the downward trend, beginning in 1998, the Department of Energy and the Nuclear Regulatory Commission launched a series of programs to support training and education in the field. Enrollments have nearly doubled since 2004, but experts say that's only enough to catch up with the demand of thelast decade.

      Soccer and the Art of Deception

      Elizabeth Pennisi

      It's common to see a soccer player fake a collision with an opponent and writhe on the ground in hopes of getting a free kick; goals have been scored and games won on wrongly awarded free kicks. To one group of researchers, the deceptive practice provided a unique research opportunity.They reported at the meeting that they have found empirical support in the antics of footballers for game-theory predictions about dishonest signals. And they have come up with ways the game might be improved.

      Getting to the Guts of Tadpole Carnivory

      Elizabeth Pennisi

      Unlike most other frogs, Budgett's frog is a carnivore even as a tadpole, and its gut reflects this voracious lifestyle: It has a very large, well-defined stomach and a short intestine, quite the contrast from the long, winding tube of most tadpoles. A developmental biologist reported at the meeting that the inhibition of a single developmental signal—retinoic acid—can yield the carnivorelike gut morphologyin a tadpole species that's normally mostly vegetarian. That suggests that it didn't take much for the Budgett's frog tadpole to evolve its unusual eating habits.

      Turtles Are Not Just Drifters

      Elizabeth Pennisi

      Biologists have long assumed that Florida sea turtles simply catch a ride in the circulating currents of the North Atlantic Ocean, which takes them north, east, down along northern Africa, and finally back around to Floridaagain. Now seven turtles with solar-powered satellite transmitters attachedto their backs have demonstrated that they do more than simply follow the currents, researchers reported at the meeting.
