Curiosity Reveals Clues to How Water Helped Shape the Landscape of Mars

How-Water-Helped-Shape-Martian-Landscape

New data from NASA’s Curiosity Rover indicate that Mount Sharp on Mars was built by sediments deposited in a large lake bed over tens of millions of years, suggesting ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet. “If our hypothesis for Mount Sharp holds up, […]

World Record in Solar Efficiency, Over 40% of Sunlight Converted into Electricity

New World Record in Solar Energy Efficiency

Researchers from the University of New South Wales have set world record in solar energy efficiency, converting over 40% of the sunlight hitting a solar system into electricity. The world-beating efficiency was achieved in outdoor tests in Sydney, before being independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in […]

Climate Models Help Reconstruct the African Humid Period

Researchers Reconstruct the African Humid Period

Using complex modeling systems, researchers have figured out the forces that drove the dramatic increase in rainfall at the end of the last ice age and marked the beginning of the African Humid Period. Providence, Rhode Island (Brown University) — During the end of the last ice age, there were dramatic changes in rainfall across […]

New Research Details Why Typhoid Toxin Targets Only Humans

Study Reveals Why Typhoid Toxin Targets Only Humans

Scientists at Yale and UC San Diego have discovered why typhoid toxin targets only humans, revealing a single oxygen atom is the cause. The bacterium Salmonella Typhi causes typhoid fever in humans, but leaves other mammals unaffected. Researchers at University of California, San Diego and Yale University Schools of Medicine now offer one explanation — […]

Astronomers Reveal a New Feature in the Evolution of Galaxies

Astronomers Find a New Feature in the Evolution of Galaxies

Using data from ESA’s Herschel space observatory and NASA’s Spitzer and Hubble space telescopes, astronomers have uncovered a new feature in the evolution of galaxies. Some like it hot, but for creating new stars, a cool cosmic environment is ideal. As a new study suggests, a surge of warm gas into a nearby galaxy — […]

New Horizons Spacecraft Awakens for Encounter with Pluto System

New Horizons Spacecraft Awakens for Encounter with Pluto

After nearly nine years and three billion miles, NASA’s New Horizons spacecraft has come out of hibernation for its long-awaited 2015 encounter with the Pluto system. Operators at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, confirmed at 9:53 p.m. (EST) that New Horizons, operating on pre-programmed computer commands, had switched from hibernation […]

Planets in Habitable Zones of M Dwarfs May Have Burned Away Chances for Life

Exoplanets May Have Burned Away Chances for Life

New research reveals that planets in the habitable zone of low-mass stars may have long since lost their chance at hosting life because of intense heat during their formative years. Planets orbiting close to low-mass stars — easily the most common stars in the universe — are prime targets in the search for extraterrestrial life. […]

Research Reveals New Strategy to Control Cellular Identity and Fate

A New Strategy to Control Cellular Identity and Fate

Newly published research suggests a new strategy to control cellular identity and fate, revealing that depleting or knocking out a chemical tag on RNA keeps embryonic stem cells in suspended animation. A team of scientists that included researchers from UCLA has discovered a novel mechanism of RNA regulation in embryonic stem cells. The findings are […]

MIT Startup LiquidPiston Develops a More Efficient Rotary Engine

Rotary Engine More Efficient than Counterparts

A new rotary engine from MIT startup LiquidPiston is lighter, quieter, and more efficient than its counterparts. Noise, excessive vibration, and relative inefficiency are drawbacks of the piston-based internal combustion engines (ICE) that power today’s lawn and garden equipment, such as leaf blowers and lawn trimmers. But now MIT startup LiquidPiston has developed a rotary […]

New Observations Confirm Variability of Young Stellar Objects

Rho Ophiuchi

Using the Spitzer Space Telescope to monitor the variability of light from 882 previously identified young stellar objects, astronomers confirm that probably all YSOs are variable at infrared wavelengths to some degree, and moreover that the younger, more deeply embedded stars often have longer and larger intensity variations, consistent with the current disk evolution picture. […]

Dawn Captures New Image of Dwarf Planet Ceres

Dawn Snaps Its Best-Yet Image of Ceres

This new image from the Dawn spacecraft was acquired as part of a final calibration of the science camera before Dawn’s arrival at Ceres. The image was taken at a distance of roughly 740,000 miles (1.2 million kilometers) from Ceres. The Dawn spacecraft has delivered a glimpse of Ceres, the largest body in the main […]

Researchers Demonstrate Superconductivity without Cooling

Superconductivity without Cooling

New research details how scientists used an infrared laser pulse to briefly modify the structure of a high-temperature superconductor, removing its electrical resistance at room temperature. Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It is already in use in some niche areas, for […]
