Telomere Extension Turns Back Aging Clock in Cultured Human Cells

Biologists from the Stanford University School of Medicine used a modified type of RNA to demonstrate a way to lengthen human telomeres by as much as 1,000 nucleotides, turning back the internal clock in these cells by the equivalent of many years of human life. A new procedure can quickly and efficiently increase the length […]

CID-42 A Recoiling Black Hole

New research from the Harvard-Smithsonian Center for Astrophysics provides new insights from deep VLA data on the potentially recoiling black hole CID-42 in the COSMOS field. When galaxies collide, the central supermassive black holes that reside at their cores will end up orbiting one another in a binary pair, at least according to current simulations. […]

Gullies Suggest Past Water on Vesta

A newly published study shows evidence that transient water flowed on the surface of Vesta, in a debris-flow-like process, and left distinctive geomorphologic features. Protoplanet Vesta, visited by NASA’s Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its […]

Milky Way Could Be a Giant Wormhole

A newly published theory reveals that the Milky Way could contain a space-time tunnel, and that the tunnel could even be the size of the galaxy itself. Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel, have you seen “Interstellar?”) and, if that were true, it would […]

LBTI Views a Dusty Star

The Large Binocular Telescope Interferometer has completed its first study of dust in the “habitable zone” around a star, opening a new door to finding planets like Earth. The findings will help in the design of future space missions that have the goal of taking pictures of planets similar to Earth, called exo-Earths. “Kepler told […]

Astronomers Observe Polarized Dust Emission of Two Dark Clouds

A new study shows for the first time that high magnetization sets the stage for the formation of massive stars with 8 solar masses or more. Magnetic fields in massive dark clouds are strong enough to support the regions against collapse due to their own gravity. A study lead by researchers at the Max Planck […]

Study Links Increased Impulsivity and Hostility With Recreational Marijuana Use

A newly published study from Yale University found that recreational marijuana use was associated with increased impulsivity and greater hostile perceptions and behaviors. While the negative effects of chronic marijuana use are being documented in a growing body of research, it has been unclear whether recreational use of the substance produces problematic effects in everyday […]

New Research Suggests That There Are More Planets in Our Solar System

Numerical calculations made by researchers at the Complutense University of Madrid and the University of Cambridge reveal that there could be at least two unknown planets hidden well beyond Pluto. If confirmed, this hypothesis would revolutionize solar system models. Astronomers have spent decades debating whether some dark trans-Plutonian planet remains to be discovered within the […]

New Exoplanet-Hunting Telescopes

The Next-Generation Transit Survey has achieved first light and will focus on discovering Neptune-sized and smaller planets, with diameters between two and eight times that of Earth. The Next-Generation Transit Survey (NGTS) is a wide-field observing system made up of an array of twelve telescopes, each with an aperture of 20 centimeters [1]. This new […]

Rivers of Glacial Meltwater Are Draining Greenland Quickly

Using satellite and field work after an extreme melt event in Greenland, new research shows that melt-prone areas on the ice sheet develop a remarkably efficient drainage system of streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. As the largest single chunk of melting snow and ice in the world, […]

Researchers Pinpoint the Position of Saturn

Using a giant array of radio-telescope antennas and data from NASA’s Cassini spacecraft, astronomers have made the most accurate determinations yet of the position of the center of mass, or barycenter, of Saturn and its numerous moons. Scientists have paired NASA’s Cassini spacecraft with the National Science Foundation’s Very Long Baseline Array (VLBA) radio-telescope system […]

Some Fossil Fuels Must Remain in the Ground to Limit Global Warming

New research led by the University College London shows that a third of oil reserves, half of gas reserves and over 80% of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target agreed by policy makers. The study funded […]

Mars Express Image of Chasms and Cliffs on Mars

This Mars Express image shows a region of Mars filled with cliffs, trenches, faults, giant plateaus and volcanoes. Although Mars is a very alien planet, some aspects of its geology are surprisingly familiar. The flowing cracks and fault-like lines in this image form part of the Claritas Rupes escarpment, a 950 km-long network of steep […]

A newly published study from Harvard Medical School reveals that using light-emitting electronic devices before bedtime can adversely impact overall health. Use of a light-emitting electronic book (LE-eBook) in the hours before bedtime can adversely impact overall health, alertness and the circadian clock, which synchronizes the daily rhythm of sleep to external environmental time cues, […]

Study Shows Tropical Forests Absorbing More Carbon Dioxide

A newly published study from NASA scientists shows that tropical forests, like the one pictured above, absorb more atmospheric carbon dioxide than boreal forests. A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study […]
