  • When continents collide: A new twist to a 50 million-year-old tale

    Updated: 2012-02-29 18:31:44
    ANN ARBOR, Mich. --- Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau. India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end and why. She conducted a study that led to surprising findings that could add a new wrinkle to the well-established theory of plate tectonics – the dominant, unifying theory of geology.read more

  • MU scientists study how to improve pesticide efficiency

    Updated: 2012-02-29 17:00:35
    COLUMBIA, Mo. – In 2007, a controversial pesticide was approved by the Food and Drug Administration for use on fruit and vegetable crops, mainly in California and Florida. Farm workers and scientists protested the approval of the pesticide because its active ingredient, methyl iodide, is a known carcinogen. Now, MU researchers are studying the molecular structure of the pesticide to determine if the product could be made more efficient and safer for those living near, and working in, treated fields. read more

  • Exotic material boosts electromagnetism safely

    Updated: 2012-02-29 15:30:58
    DURHAM, N.C. -- Using exotic man-made materials, scientists from Duke University and Boston College believe they can greatly enhance the forces of electromagnetism (EM), one of the four fundamental forces of nature, without harming living beings or damaging electrical equipment. This theoretical finding could have broad implications for such applications as magnetic levitation trains, which ride inches above the tracks without touching and are propelled by electro-magnets.read more

  • New method to separate much-needed medical isotopes

    Updated: 2012-02-29 00:31:44
    Individual atoms of a certain chemical element can be very stubborn when it comes to separation, mainly because techniques rely on a difference in chemical and physical properties — atoms are almost identical in both regards. However, if you peer closely enough into the atoms, there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of medicine and nuclear energy and now researchers have proposed a novel way of isolating them.read more

  • Sea level rise to alter economics of California beaches

    Updated: 2012-02-28 16:01:26
    DURHAM, N.C. -- Rising sea levels are likely to change Southern California beaches in the coming century, but not in ways you might expect. While some beaches may shrink or possibly disappear, others are poised to remain relatively large -- leaving an uneven distribution of economic gains and losses for coastal beach towns, according to a study by researchers at Duke University and five other institutions.read more

  • Direct measurement of the formation length of photons

    Updated: 2012-02-28 15:02:26
    How long does it take an electron to form a photon? The answer would normally be: so short a time that it cannot be measured. However, the international CERN team responsible for experiment NA63 -- mainly staffed by physicists from Aarhus University -- has now succeeded in dragging out the process, thereby making it measurable. They achieved this by utilising the phenomena of objects moving slower and shortening in length from Einstein's theory of relativity, along with two pieces of gold foil and a micrometre screw.read more

  • Modified bone drug kills malaria parasite in mice

    Updated: 2012-02-27 22:00:35
    CHAMPAIGN, Ill. — A chemically altered osteoporosis drug may be useful in fighting malaria, researchers report in a new study. Unlike similar compounds tested against other parasitic protozoa, the drug readily crosses into the red blood cells of malaria-infected mice and kills the malaria parasite. The drug works at very low concentrations with no observed toxicity to the mouse. The study appears in the Proceedings of the National Academy of Sciences.read more

  • Call for tough new targets on European Union energy reduction

    Updated: 2012-02-27 00:30:18
    Energy efficiency experts at the University of East Anglia (UEA) are calling for ambitious new targets to reduce energy demand across the European Union. In a report published today by the Build with CaRe consortium, the researchers propose a new EU target of a 40 per cent reduction in primary energy demand by 2050. The existing target is a 20 per cent improvement in energy efficiency by 2020, but the EU is currently on track to achieve only half of this. read more

  • How heavy and light isotopes separate in magma

    Updated: 2012-02-24 16:30:09
    <pIn the crash-car derby between heavy and light isotopes vying for the coolest spots as magma turns to solid rock, weightier isotopes have an edge, research led by Case Western Reserve University shows. This tiny detail may offer clues to how igneous rocks form. As molten rock cools along a gradient, atoms want to move towards the cool end. This happens because hotter atoms move faster than cooler atoms and, therefore, hotter atoms move to the cool region faster than the cooler atoms move to the hot region.read more

  • Evolution of earliest horses driven by climate change

    Updated: 2012-02-24 16:00:05
    When Sifrhippus sandae, the earliest known horse, first appeared in the forests of North America more than 50 million years ago, it would not have been mistaken for a Clydesdale. It weighed in at around 12 pounds--and it was destined to get much smaller over the ensuing millennia. Sifrhippus lived during the Paleocene-Eocene Thermal Maximum (PETM), a 175,000-year interval of time some 56 million years ago in which average global temperatures rose by about 10 degrees Fahrenheit.read more
