Length of Telomeres Predicts Susceptibility to the Common Cold

Researchers Identify Biological Marker That Predicts Susceptibility to the Common Cold

Researchers have identified a biological marker that predicts susceptibility to the common cold, finding that participants with shorter telomeres were more likely to become infected by the cold virus. PITTSBURGH – Researchers at Carnegie Mellon University have identified a biological marker in the immune system that – beginning at about age 22 – predicts our […]

Cassini Detects Particles Being Accelerated to Ultra-High Energies

Cassini Sheds Light on Cosmic Particle Accelerators

Similar to the particle acceleration that takes place around supernovas, observations from NASA’s Cassini spacecraft have detected particles being accelerated to ultra-high energies by an unusually strong solar system shock wave. During a chance encounter with what appears to be an unusually strong blast of solar wind at Saturn, NASA’s Cassini spacecraft detected particles being […]

NASA’s THEMIS Mission Tracks Space Weather & the Magnetosphere

THEMIS Understanding the Magnetosphere

Launched in 2007, the THEMIS mission has helped highlight a number of crucial details about what causes space weather events and has dramatically improved our understanding of the magnetosphere. On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the […]

New X-ray Tool Better Pinpoints the Arrival Time of X-ray and Other Laser Pulses

Pump Probe Technique

In a newly published study, scientists from the SLAC National Accelerator Laboratory detail a new set of tools that better pinpoint the arrival time of X-ray and other laser pulses to within a few femtoseconds of accuracy. With SLAC’s Linac Coherent Light Source X-ray laser, timing is everything. Its pulses are designed to explore atomic-scale […]

The Search for Exoplanets Intensifies

Kepler 11 Which Has Six Stars in Tight Orbit Around It

Aided by technology, astronomers at the University of Chicago search for far-off planets like Earth. When astronomers discovered planet GJ 1214b circling a star more than 47 light-years from Earth in 2009, their data presented two possibilities: Either it was a mini-Neptune shrouded in a thick atmosphere of hydrogen and helium, or it was a […]

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 […]

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 […]
