Recent international studies of math and science education suggest that students in the United States are falling further behind their foreign counterparts.
The American Institute of Physics (AIP) announced the three winning entries in the 2009 Science Communication Awards today.
Funding will ensure that scientists continue transformational research, leading to technologies that spur innovation and generate clean energy jobs to keep the nation competitive in a global economy.
Military agencies wanted a death ray, and they were willing to pay for it. That was one of the forces spurring scientists in a race that ended with the invention of the laser in 1960, fifty years ago this May. A new exhibit on the award-winning Web site of the Center for History of Physics, American Institute of Physics (AIP) tells the remarkable story of the laser's invention using the voices of the scientists themselves.
The American Association of Physicists in Medicine (AAPM) has issued a statement today in the wake of several recent articles in the New York Times yesterday and earlier in the week that discuss a number of rare but tragic events in the last decade involving people undergoing radiation therapy.
Secret military projects, powerful collisions at the LHC, future international physics projects, and lots of new data from around the universe will be featured in talks at this year's spring meeting of The American Physical Society (APS), the largest professional society of physicists in the world.

An expert panel of librarians, library scientists, publishers, and university academic leaders today called on federal agencies that fund research to develop and implement policies that ensure free public access to the results of the research they fund “as soon as possible after those results have been published in a peer-reviewed journal.”
Statement seeks to put fears of CT radiation dose and dose-related effects into perspective and to correct potential misunderstandings
Science journalists should mark their calendars for the two most important physics meetings of the year. The American Physical Society (APS) is hosting its two annual meetings in Washington, D.C. (February 13-16) and in Portland, OR (March 15-19).
Paul S. Otellini, President and Chief Executive Officer of Intel Corporation, has accepted the invitation of the Task Force on American Innovation to serve as its new chair.
A team of researchers at the University of California, San Diego and Stanford University has developed a way to simulate blood flow on the computer to optimize surgical designs. It is the basis of a new tool that may help surgeons plan for a life-saving operation called the "Fontan" surgery, which is performed on babies born with severe congenital heart defects.
Last year, the United States overtook Germany to become the largest producer of wind energy in the world. This capped a five year expansion of U.S. wind power during which capacity increased by about a third every year.
When people speak, sing, or shout, they produce sound by pushing air over their vocal folds -- bits of muscle and tissue that manipulate the air flow and vibrate within it. When someone has polyps or some other problem with their vocal folds, the airflow can be altered, affecting the sound production.
A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs.
When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells. Inside the blood cells, the parasites replicate and also begin to expose adhesive proteins on the cell surface that change the physical nature of the cells in the bloodstream.
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.
A butterfly’s proboscis looks like a straw -- long, slender, and used for sipping -- but it works more like a paper towel, according to Konstantin Kornev of Clemson University. He hopes to borrow the tricks of this piece of insect anatomy to make small probes that can sample the fluid inside of cells.
To design a lightweight anchor that can dig itself in to hold small underwater submersibles, Anette (Peko) Hosoi of MIT borrowed techniques from one of nature’s best diggers -- the razor clam.
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity. They will present their concept later this month at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneapolis Convention Center.
If a nuclear weapon were detonated in a metropolitan area, how large would the affected area be? Where should first responders first go? According to physicist Fernando Grinstein, we have some initial understanding to address these questions, but fundamental issues remain unresolved.
The virtual Press Room for next week's 62st Annual Meeting of the American Physical Society (APS) Division of Fluid Dynamics in Minneapolis is now open. See http://www.aps.org/units/dfd/pressroom/.
The Council of the American Physical Society has overwhelmingly rejected a proposal to replace the Society’s 2007 Statement on Climate Change with a version that raised doubts about global warming.
The practice of sterilizing medical tools and devices helped revolutionize health care in the 19th century because it dramatically reduced infections associated with surgery. Through the years, numerous ways of sterilization techniques have been developed, but the old mainstay remains a 130-year-old device called an autoclave, which is something like a pressure steamer. The advantage of the autoclave is that the unsterile tools can be packed into sealed containers and then processed, staying sealed and sterile after they are removed.
Tooth enamel is hardest material in the human body because it's made almost entirely of minerals. As tough as it may be, however, enamel can be broken down by bacteria, forming cavities and eventually destroying the tooth. That's why dentists repair cavities by filling them with a material to replace the lost enamel. The most common such restorative is a material invented in the 19th-century known as amalgam -- the classic silver-black fillings many people have.
Of the many characteristic traits a drug can have, one of the most desirable is the ability for a drug to be swallowed and absorbed into the bloodstream through the gut. Some drugs, like over-the-counter aspirin, lend themselves to this mode of delivery and are trivial to take. They can be pressed into a pill and swallowed. Other drugs cannot be swallowed and must be administered instead through more complicated routes. Insulin, for instance, must be injected.
Eric Shaqfeh studies blood at Stanford University, using computer models that simulate how the fluid and the cells it contains move around. On November 11 at a meeting of the scientific society AVS, he will present his latest unpublished findings from two studies. One shows how components in blood line up to prepare for healing; the other demonstrates the best shape to use for man-made nanoparticles that target cancers -- a surfboard.
Dana Filoti of the University of New Hampshire will present thin films of silver and copper she has developed that can kill bacteria and may one day help to cut down on hospital infections. The antimicrobial properties of silver and copper have been known for centuries -- last year, the U.S. Environmental Protection Agency officially registered copper alloys, allowing them to be marketed with the label "kills 99.9% of bacteria within two hours." Copper ions are known to penetrate bacteria and disrupt molecular pathways important for their survival.
The American Institute of Physics (AIP) is awarding the 2010 Prize for Industrial Applications of Physics next month to Robert Street of the Palo Alto Research Center (PARC) in California. The prize is supported by General Motors.
The AVS 56th International Symposium & Exhibition next month in San Jose, CA will showcase advances in alternative energy, materials research, nanotechnology, and medicine. Highlights of papers from among the 1,250 talks and posters at the meeting are described below.
The Task Force on American Innovation today unveiled a new website, www.innovationtaskforce.org, which offers fresh and comprehensive information on federal policies and appropriations for key agencies that fund research in the physical sciences, engineering, and mathematics.
Many of nature's most fascinating phenomena involve forms of fluid flow -- the motions of liquids and gases -- from the flight of golf and tennis balls to the slip of a red blood cell, the flap of an elephant ear, the line of a wildfire, the spin of a storm, or the formation of a crater on the Moon.
Monitoring the daily ship traffic of a busy waterway like the Hudson River isn't an easy task for the Department of Homeland Security. The biggest ships are required to carry an Automatic Identification System that broadcasts information about their identity and location, but boats weighing less than 300 tons are often an invisible security risk.
The question of how hormones affect a woman's voice is relevant to professional singers because hormonal fluctuations may place them at risk of injury. Knowing when the risks are greatest would help singers avoid performing at those times -- in the same way that a track star with a bad knee will sit out a competition.
Try to pronounce the words "caught" and "cot." If you're a New Yorker by birth, the two words will sound as different as their spellings. But if you grew up in California, you probably pronounce them identically.
How does the voice of a woman differ from the voice of man? You might think that pitch is the big difference, but according to speech pathologist James Dembowski, you would be wrong. And he should know -- for the last year, he has been working with a middle-aged transgendered woman born as a boy, teaching "Ms. J" to use her male vocal anatomy to speak in a womanly way.
Teachers tend to spend more time speaking than most professionals, putting them at a greater risk for hurting their voices -- they're 32 times more likely to experience voice problems, according to one study. And unlike singers or actors, teachers can't take a day off when their voices hurt.
What do a West African drummer and a sperm whale have in common? According to some reports, they can both spot rhythms in the chatter of an ocean crowded with the calls of marine mammals -- a feat impossible for the untrained human ear.
Everyone listens to music at least now and then. For many of us, music is a casual experience, a moment's entertainment. But for those who practiced in a school orchestra or who play a musical instrument professionally, the musical experience can be something more.
"Darwin's Golden Retriever" Dr. Eugenie Scott has received the California Academy of Sciences' highest honor: the Fellows Medal.
Next month in San Jose, CA, the AVS 56th International Symposium & Exhibition will showcase a spectrum of science and engineering research that is leading to breakthroughs in nanotechnology, alternative energy, materials research, and medicine -- from fuel cells and batteries of the future to programmable materials and innovative approaches to drug design.
How does a woman's voice differ from a man's? Can being a good listener help a whale survive? Do babies who briefly hear a foreign language start to babble in that language?
How does video game sound trigger panic attacks? Can beams of ultrasound energy prevent kidney stones? What is science telling us about the voices of teachers, the sound of bats, and the noises of a high school gymnasium?
A physicist created the World Wide Web in 1989 as a tool for helping far-flung scientific collaborators share data, and in the two decades since its invention, the Web has changed the world. Now a new Web-based tool for the physics community, called AIP UniPHY, promises to help physicists change the world again.
A group of researchers at Johns Hopkins University has designed nanoparticles that can carry cancer-treating radioisotopes through the body and deliver them selectively to tumors. Today in Anaheim, CA, they will report the latest results of their research, including studies in animal models, at the 51st meeting of the American Association of Physicists in Medicine (AAPM).
When doctors are managing care for women with breast cancer, the information available to them profoundly influences the type of care they recommend. Knowing whether a woman's cancer has metastasized, for instance, directly affects how her doctors will approach treatment -- which may in turn influence the outcome of that treatment.
