  • Pitch of blue whale songs is declining around the world, scientists discover
    The sound level of songs blue whales sing across the vast expanses of the ocean to attract potential mates has been steadily creeping downward for the past few decades, and scientists believe the trend may be good news for the population of the endangered marine mammal.
  • Worms unlock secrets to new epilepsy treatments
    Scientists have used worms to reel in information they hope will lead to a greater understanding of cellular mechanisms that may be exploited to treat epilepsy. In a new study, the researchers explain how the transparent roundworm, C. elegans, helped them identify key "molecular switches" that control the transport of a molecule (gamma-aminobutyric […]
  • World-Record Energy Collisions Achieved at Large Hadron Collider
    On December 8th, thousands of physicists around the world cheered as CERN's Large Hadron Collider (LHC) smashed together subatomic particles at the highest energies ever reached by a human-made accelerator and the giant ATLAS detector observed the products of the record-breaking reactions whizzing through its sophisticated tracking devices.
  • Stem cell derived neurons for research relevant to Alzheimer's and Niemann-Pick type C diseases
    Stem cell derived neurons may allow scientists to determine whether breakdowns in the transport of proteins, lipids and other materials within cells trigger the neuronal death and neurodegeneration that characterize Alzheimer's disease and the rarer but always fatal neurological disorder, Niemann-Pick Type C, according to a recent presentation. Early de […]
  • Energy efficiency technologies offer major savings, report finds
    Energy efficiency technologies that exist today or that are likely to be developed in the near future could save considerable money as well as energy, says a new report from the National Research Council. Fully adopting these technologies could lower projected US energy use 17 percent to 20 percent by 2020, and 25-31 percent by 2030.
  • Money changes what we think is fair, research finds
    Thinking of rewarding your sales department for a job well done? You might not want to make cash part of the payoff.
  • Why King Kong failed to impress: Humans, apes use odor-detecting receptors differently
    Humans have the same receptors for detecting odors related to sex as do other primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to researchers.
  • Delivering medicine directly into a tumor
    Researchers have identified a peptide (a chain of amino acids) that specifically recognizes and penetrates cancerous tumors but not normal tissues. The peptide was also shown to deliver diagnostic particles and medicines into the tumor.
  • Fine-tuned laser: Step toward airport scanners that can identify explosives
    Engineers have developed the first practical method for tuning terahertz quantum cascade lasers. What's more, the method is a fundamentally new approach to laser tuning that could have implications for other emerging technologies.
  • H1N1 influenza adopted novel strategy to move from birds to humans
    The 2009 H1N1 virus, which ignited a worldwide "swine flu" panic earlier this year, used a novel strategy to cross from birds into people, scientists have found. The finding could help those surveilling the world for new flu variants and those developing antiviral drugs.
