ALMA Views Early Universe Star Factories

ALMA Exposes Hidden Star Factories

Using the Atacama Large Millimeter/submillimeter Array (ALMA) and gravitational lensing, scientists have obtained new measurements of some of the oldest galaxies in the universe, revealing that some of the most vigorous bursts of star birth in the cosmos took place much earlier than previously thought. Observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that […]

Atomic Collapse State Observed on Graphene

Atomic Collapse State Observed in Graphene

Using an artificial atomic nuclei fabricated on graphene, a team of researchers imaged the “atomic collapse” states theorized to occur around super-large atomic nuclei. The first experimental observation of a quantum mechanical phenomenon that was predicted nearly 70 years ago holds important implications for the future of graphene-based electronic devices. Working with microscopic artificial atomic […]

Finding the Asteroids That Threaten Earth

The Sentinel Mission to Track Asteroids That Threaten Earth

By building an asteroid-hunting space telescope called Sentinel, the B612 Foundation aims to track down the thousands of unknown asteroids that could pose a threat to Earth. On Saturday, an asteroid the size of one and a half football fields flew within 240,000 miles of Earth. If the space rock had hit land, it would […]

Number of Potentially Habitable Planets is Greater Than Previously Thought

Number of Potentially Habitable Planets is Greater Than Previously Thought

New research from Penn State suggests that the number of Earth-sized planets in the habitable zones of low-mass stars is more common than previously thought. University Park, Pennsylvania — The number of potentially habitable planets is greater than previously thought, according to a new analysis by a Penn State researcher, and some of those planets […]

Yale Researchers Engineer a System to Deliver a Safer Vaccine

Scientists Trick Bacteria to Deliver a Safer Vaccine

In a newly published study, Yale University researchers detail how they engineered a system that tricks bacteria to deliver a safer vaccine, which could be used to combat cancer as well as a wide variety of infectious diseases. Vaccines that employ weakened but live pathogens to trigger immune responses have inherent safety issues but Yale […]

Lunar Impact Created a Sea of Molten Rock Six Miles Deep

Lunar Impacts Created an Ocean of Molten Rock

An analysis of the data from NASA’s Lunar Orbiter Laser Altimeter reveals that molten rock covered the Moon’s surface on more than one occasion, showing that an impact event produced a sea of melted rock 220 miles across and at least six miles deep with similar seas probably present at various times. Providence, Rhode Island […]

Curiosity Reveals that Mars Could Have Supported Life

Conditions on Mars Once Suited for Life

Researchers have identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon in the powder rock sample obtained by NASA’s Curiosity rover, suggesting that Mars could have supported life. Pasadena, California — An analysis of a rock sample collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes. Scientists identified sulfur, nitrogen, hydrogen, oxygen, […]

CT Scans of Mummies Reveal Clogged Arteries

Ancient Hunter Gatherers Suffered from Clogged Arteries

Using CT scans on mummies from four different geographical locations, researchers report that atherosclerosis may have been more common among ancient populations than previously thought, finding that over a third of the mummies had probable or definite atherosclerosis. Like nearly 4.6 million Americans, ancient hunter-gatherers also suffered from clogged arteries, revealing that the plaque build-up […]

Cassini Captures New Images of Saturn’s Moon Rhea

Cassini Images of Rhea

NASA’s Cassini spacecraft captured several new photos of Saturn’s moon Rhea as it flew by Rhea at an altitude of 620 miles (997 kilometers) on March 9, 2013. Following its last close flyby of Saturn’s moon Rhea, NASA’s Cassini spacecraft captured these raw, unprocessed images of the battered icy moon. They show an ancient, cratered […]
