Washington, DC--A team of experimental and computational scientists led by Carnegie's Tim Strobel and Venkata Bhadram have synthesized a long sought-after form of titanium nitride, Ti3N4, which has promising mechanical and optoelectronic properties.
Every winter, doctors' offices and hospital emergency rooms fill with children who have bronchiolitis, an inflammation of the small airways in the lung. It's responsible for about 130,000 admissions each year. Sometimes these young patients have symptoms reminiscent of a bad cold with a fever, cough and runny nose. Other times, bronchiolitis causes breathing troubles so severe that these children end up in the intensive care unit.
The warming climate is expected to affect coastal regions worldwide as glaciers and ice sheets melt, raising sea level globally. For the first time, an international team has found evidence of how sea-level rise already is affecting high and low tides in both the Chesapeake and Delaware bays, two large estuaries of the eastern United States.
The team combined a computer model with 100 years of observations to tease out the fact that global sea-level rise is increasing the tidal range, or the distance between the high and low tides, in many areas throughout each bay.
Scientists at the University of Southampton have discovered a way of enhancing the capabilities of an emerging nanotechnology that could open the door to a new generation of electronics.
In a study published in the journal Scientific Reports, researchers show how they have pushed the memristor - a simpler and smaller alternative to the transistor, with the capability of altering its resistance and storing multiple memory states - to a new level of performance after experimenting with its component materials.
CAMBRIDGE, Mass. -- A type of virus that dominates water samples taken from the world's oceans has long escaped analysis because it has characteristics that standard tests can't detect. However, researchers at MIT and the Albert Einstein College of Medicine have now managed to isolate and study representatives of these elusive viruses, which provide a key missing link in virus evolution and play an important role in regulating bacterial populations, as a new study reports.
Washington, DC-- Plumes of hot rock surging upward from the Earth's mantle at volcanic hotspots contain evidence that the Earth's formative years may have been even more chaotic than previously thought, according to new work from a team of Carnegie and Smithsonian scientists published in Nature.
It is well understood that Earth formed from the accretion of matter surrounding the young Sun. Eventually the planet grew to such a size that denser iron metal sank inward, to form the beginnings of the Earth's core, leaving the silicate-rich mantle floating above.
Accurately measuring electric fields is important in a variety of applications, such as weather forecasting, process control on industrial machinery, or ensuring the safety of people working on high-voltage power lines. Yet from a technological perspective, this is no easy task.
CORVALLIS, Ore. - Exposure to a compound used to treat migraines and seizures causes characteristics associated with autism, groundbreaking research with zebrafish has demonstrated.
The study conducted by Oregon State University and Wenzhou Medical University showed valproic acid exposure resulted in phenotypes and behaviors consistent with autism spectrum disorder, or ASD, and validated zebrafish as a model for studying ASD and its causes.
Leprosy is an infectious disease with gruesome symptoms. It damages the skin, peripheral nerves, the upper respiratory tract, and the eyes. Despite being curable with multidrug therapy, leprosy still persists in many developing countries, with more than 200,000 new cases every year and increasing drug-resistant strains of the leprosy bacterium, Mycobacterium leprae, emerging.
Forensic researchers at North Carolina State University have found a more accurate way to assess an individual's age at death, based on the bone mineral density of the femur. The technique could be used to help identify human remains.
