  • Disease-carrying fleas abound on New York City's rats
    In the first study of its kind since the 1920s, rats in New York City were found to carry a flea species capable of transmitting plague pathogens. Among them: 500-plus Oriental rat fleas, notorious for their role in transmitting the bubonic plague, also known as the Black Death.
  • BPA exposure linked to autism spectrum disorder, study reports
    A newly published study is the first to report an association between bisphenol-A (BPA), a common plasticizer used in a variety of consumer food and beverage containers, with autism spectrum disorder (ASD) in children.
  • Perfect NCAA bracket? Near impossible: Mathematician says
    The odds of picking a perfect bracket for the NCAA men's basketball March Madness championship tournament are a staggering less than one in 9.2 quintillion (that's 9,223,372,036,854,775,808), according to a mathematics professor.
  • New research aims to refine increasingly popular plastic surgery procedures: ...
    Two of the fastest-growing plastic surgery procedures are gluteoplasty or "butt augmentation," to improve the appearance of the buttocks; and labiaplasty to address cosmetic and functional concerns with the vagina. New insights into the use and outcomes of these procedures are presented in a new art...
  • Is 'the dress' white and gold or blue and black? Visual perception expert wei...
    On Feb. 26, a picture of a cocktail dress originally uploaded to the blog Tumblr swept the Internet and managed to divide the population over a simple question: What color is the dress? Some viewers saw gold and white while others insisted the dress is blue and black. Some people claimed they could ...
  • Colon + septic tank = unique, at times stinky, study
    What do a human colon, septic tank, copper nanoparticles and zebrafish have in common? They were the key components used by researchers to study the impact copper nanoparticles, which are found in everything from paint to cosmetics, have on organisms inadvertently exposed to them.
  • New assessment tool can predict successful teachers
    A new video assessment tool that can inform teacher selection and hiring has implications for education reform, a new study concludes. The researchers say there is a growing focus as part of education reform and accountability efforts to improve mechanisms for selecting individuals into teacher prep...
  • Pens filled with high-tech inks for do-it-yourself sensors
    A new simple tool developed by nanoengineers is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field. Scientists have developed high-tech inks that react with several chemicals, including ...
  • Reducing animal testing for skin allergies
    The JRC has validated and recommended a new method which is not based on animal testing, to identify chemicals that can trigger skin allergies, estimated to affect already 20% of the population in Europe.
  • Forbidden atomic transitions: Controlling matter 1,000 times more precisely u...
    A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible. Physicists have demonstrated "ponderomotive spectroscopy," which allows researchers to peer more deeply into the structure of atoms and direct t...
  • Genetically speaking, mammals are more like their fathers
    You might resemble or act more like your mother, but a novel research study reveals that mammals are genetically more like their dads. Specifically, the research shows that although we inherit equal amounts of genetic mutations from our parents -- the mutations that make us who we are and not some o...
  • Scientists override body's inflammatory response
    Scientists who have discovered the mechanism of a protein that suppresses inflammation in the body, say the information could potentially be used to develop new drugs to control inflammation. The study is universally applicable to all types of inflammation in patients of all ages, in conditions rang...
  • Low sugar uptake in brain appears to exacerbate Alzheimer's disease
    A deficiency in the protein responsible for moving glucose across the brain's protective blood-brain barrier appears to intensify the neurodegenerative effects of Alzheimer's disease, according to a new mouse study. The research suggests that targeting the protein called GLUT1 could help prevent or ...
  • Core work: Iron vapor gives clues to formation of Earth and moon
    One of the world's most powerful radiation sources provides scientists clues about Earth's formation and how iron vaporizes.
  • Scientists crack piece of neural code for learning, memory
    Researchers describe how postmortem brain slices can be 'read' to determine how a rat was trained to behave in response to specific sounds, a new article suggests. The work provides one of the first examples of how specific changes in the activity of individual neurons encode particular acts of lear...
  • Minors easily able to purchase electronic cigarettes online
    Teenagers in North Carolina were easily able to buy electronic cigarettes online because both Internet vendors and shipping companies failed to verifying ages in a study that assessed compliance with North Carolina's 2013 e-cigarette age-verification law, according to an article.
  • Survey of teen dating violence among US high school students
    A survey of US high school students suggests that 1 in 5 female students and 1 in 10 male students who date have experienced some form of teen dating violence (TDV) during the past 12 months. "These results present broader implications for TDV prevention efforts. Although female students have a high...
  • Cerebral blood flow as a possible marker for concussion outcomes
    Cerebral blood flow recovery in the brain could be a biomarker of outcomes in patients following concussion, a new imaging study suggests. Most of the 3.8 million sports-related traumatic brain injuries (TBIs) that occur annually are concussions. Developing methods to diagnose the presence and sever...
  • OSIRIS-REx mission successfully completes system integration review
    This week marked the completion of an important step on the path to spacecraft assembly, test, and launch operations for the Origins Spectral Interpretation Resource Identification Security Regolith Explorer or OSIRIS-REx mission.
  • Freeze! Watching alloys change from liquid to solid could lead to better metals
    If you put a camera in the ice machine and watched water turn into ice, the process would look simple. But the mechanism behind liquids turning to solids is actually quite complex, and understanding it better could improve design and production of metals. A recent investigation aboard the Internatio...
