The large, big-beaked "terror birds" (Phorusrhacidae) didn't need flight to snag a Miocene meal. Some of these extinct, flightless fowl likely used their massive rigid skulls and hooked beaks to chomp into prey with strong, successive pulls, concluded a research team after performing a biomechanical analysis of fossilized skulls...
Nearly a decade after the U.S. launched its National Nanotechnology Initiative (NNI), the program's $12 billion in funding has helped place the country at the head of the pack regarding the development of science and technology measured in billionths of meters...
Infectious tropical diseases such as river blindness and trachoma can be compelling targets around which to rally government and community campaigns to combat these scourges.
As speculation swirls around the status of possible investigations into research by the prolific Harvard psychologist Marc Hauser, a new study drills down to figure out the true cost of scientific misconduct...
A child that is easily distracted, fidgety and interruptive in school might not have a clinical case of attention-deficit hyperactivity disorder (ADHD), but might rather just be acting his or her age, posit researchers behind two new studies of diagnosis trends...
Medical science has known for some time that the direction of a bone fracture depends on how quickly the bone is compressed. If the bone is squeezed slowly, the break proceeds cross-wise...
A new analysis of surgeries completed in developing countries revealed a surgical mortality rate of just 0.2 percent, suggesting that when well-trained and outfitted staff are available, surgery can be quite safe in areas of violent conflict, such as Southern Sudan...
Scientists are still assessing the ecological damage wrought by the Deepwater Horizon oil spill in the Gulf of Mexico earlier this year. Other researchers, however, are looking at subtler signs of the disaster's potential impacts on human health...
The heart's electrical pulse has made possible the modern-day pacemaker, a device that has helped keep millions of human hearts beating. Such invasive devices, however, have proved difficult to use on small, delicate embryonic animal hearts, which some researchers study to learn more about the early stages of heart development, as well as to develop new treatments for disorders...
A blue-ribbon National Academy of Sciences committee released its decadal survey of astronomy and astrophysics projects August 13, revealing its recommendations for 2012 to 2021.
