Study Links Levels of Air Pollution and Ozone to Cardiac Arrest

Link Between Ozone Levels and Cardiac Arrest

Based on a massive data set unique to Houston, a newly published study from scientists at Rice University has found a direct correlation between out-of-hospital heart attacks and levels of air pollution and ozone. Researchers at Rice University in Houston have found a direct correlation between out-of-hospital cardiac arrests and levels of air pollution and […]

Neuroassessment Device Quantitatively Measures Neuromuscular Performance

NeuroAssess

Researchers at the Wyss Institute have completed the first clinical study of a new rapid neuroassessment device they developed to quantitatively measure neuromuscular performance and are currently conducting a study with athletes in the Boston area to determine the sensitivity of the technology in diagnosing concussions. Doctors routinely track their patients’ hand-eye coordination to monitor […]

Presence of Water in the Primary Crust Indicates that the Early Moon was Wet

Traces of Water Found in Genesis Rock

New findings from the University of Michigan indicate that the early moon was wet and that water there was not substantially lost during the moon’s formation, contradicting the predominant lunar formation theory. Ann Arbor— Traces of water have been detected within the crystalline structure of mineral samples from the lunar highland upper crust obtained during […]

Fossilized Crinoids Yield the Oldest Biomolecules Found Inside a Fossil

Fossilized Sea Creatures Yield Oldest Biomolecules

Researchers from Ohio State University have discovered the oldest example of biomarkers found inside a particular complete fossil. Columbus, Ohio—Though scientists have long believed that complex organic molecules couldn’t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption. The spindly animals with feathery arms—called crinoids, […]

Scientists Develop Silicon-Based Light-Emitting Diodes (SiLEDs)

Multicolor LEDs Without Heavy Metals

Researchers have developed silicon-based light-emitting diodes (SiLEDs) that have the ability to change color from the deep red down to the yellow-orange spectral region by using nanoparticles. Silicon nanocrystals have a size of a few nanometers and possess a high luminous potential. Scientists of KIT and the University of Toronto/Canada have now succeeded in manufacturing […]

Astrophysicists Confirm Cosmic Rays Come from Exploding Stars

Cosmic Rays Come From Exploding Stars

Using data from NASA’s Fermi Gamma-ray Space Telescope, researchers confirmed that cosmic rays do indeed come from exploding supernovas. A new study confirms what scientists have long suspected: Cosmic rays – energetic particles that pelt Earth from all directions – are born in the violent aftermath of supernovas, exploding stars throughout the galaxy. A research […]

Yale Study Shows No Link between Hospital Readmissions and Death Rates

No Link Between Hospital Readmissions and Death Rates

New research from Yale University shows that many health institutions do well on mortality and readmission and that performance on one does not dictate performance on the other. Hospital performance on two Medicare quality measures are not strongly related, and are likely to reflect very different aspects of their clinical care, according to results published […]

Nano-Machines Recreate Principal Activities of Proteins

Nano Machines for Bionic Proteins

Using a high performance computing infrastructure, a team of researchers developed the first versatile and modular example of a fully artificial protein-mimetic model system that recreates principal activities of proteins. Physicists of the University of Vienna together with researchers from the University of Natural Resources and Life Sciences Vienna developed nano-machines which recreate principal activities […]

Calcified Bacteria Sheds Light on the Health Consequences of the Evolving Diet

Ancient Teeth Bacteria Record Disease Evolution

A newly published study from the University of Adelaide shows that calcified dental plaque (dental calculus) found on ancient teeth from 34 early European skeletons indicates that the transition from hunter-gatherer to farming shifted the oral microbial community to a disease-associated configuration. DNA preserved in calcified bacteria on the teeth of ancient human skeletons has […]

Hubble Views a Pair of Interacting Galaxies Known as IC 2184

A Pair of Interacting Galaxies Known as IC 2184

Composed of visible and infrared observations from Hubble’s Wide Field and Planetary Camera 2, this Hubble image shows a pair of interacting galaxies known as IC 2184. This large “flying V” is actually two distinct objects — a pair of interacting galaxies known as IC 2184. Both the galaxies are seen almost edge-on in the […]
