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, […]

Astronomers Discover a Rare Triple Quasar

A Rare Triple Quasar Discovered

By combining telescope observations with advanced modeling, astronomers have found a rare triple quasar, called QQQ J1519+062. For only the second time in history, a team of scientists including Michele Fumagalli from the Carnegie Institution for Science in the United States have discovered an extremely rare triple quasar system. Their work is published in the […]

The First Remote Reconnaissance of Another Solar System

Astronomers Conduct First Remote Reconnaissance of Another Planetary System

A team of astronomers have conducted the first remote reconnaissance of another solar system, collecting the first chemical fingerprints of this system’s four red exoplanets, which orbit a star 128 light years away from Earth. Researchers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through […]

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 […]

A Close Star System Discovered, Only 6.5 Light Years Away

Close Binary System Discovered

In a new research paper, Penn State researcher Kevin Luhman describes the discovery the third-closest star system to the Sun, WISE J104915.57-531906. Both stars in this newly discovered binary system are “brown dwarfs” and are located about 6.5 light years away. A pair of newly discovered stars is the third-closest star system to the Sun, […]

Scientists Discover an Outflow from a Young Protostar

A New Telescope Probes a Young Protostar IRAS 16293 2922B

Using the Atacama Large Millimeter/submillimeter Array, scientists discovered an outflow from a young protostar, marking a dramatic step towards understanding the earliest stages of a star’s life. IRAS 16293-2922B is a very young star – a protostar – perhaps only about ten thousand years old. Slightly smaller in mass than our Sun, it is still […]

Scientists Create a 3D View of the Ancient Water Channels of Mars

Visualization of Buried Marte Vallis Channels

Using data from NASA’s Mars Reconnaissance Orbiter, scientists create a 3D reconstruction of ancient water channels below the Martian surface. Pasadena, California — NASA’s Mars Reconnaissance Orbiter took numerous images during the past few years that showed channels attributed to catastrophic flooding in the last 500 million years. During this period, Mars had been otherwise […]

Telomere Length Predicts the Life Expectancy of Patients with Heart Disease

Length of DNA Strands in Patients With Heart Disease Can Predict Life Expectancy

In a new study, scientists were able to predict survival rates among patients with heart disease based on the length of strands of DNA found on the ends of chromosomes known as telomeres. San Francisco, California – Can the length of strands of DNA in patients with heart disease predict their life expectancy? Researchers from […]
