NASA’s AIM Spacecraft Observes Noctilucent Clouds

AIM Spacecraft Observes Noctilucent Clouds

This composite image shows noctilucent clouds over the Arctic captured by NASA’s Aeronomy of Ice in the Mesosphere Spacecraft. In the late spring and summer, unusual clouds form high in the atmosphere above the polar regions of the world. As the lower atmosphere warms, the upper atmosphere gets coooler, and ice crystals form on meteor […]

Cassini Reveals Titan’s Atmosphere Even More Earth-like Than Previously Thought

PIA18309: Frozen Paradise

New research reveals that Titan’s atmosphere is even more Earth-like than previously thought and provides evidence for why Titan’s atmosphere is losing about seven tonnes of hydrocarbons and nitriles every day. Scientists at UCL have observed how a widespread polar wind is driving gas from the atmosphere of Saturn’s moon Titan. The team analyzed data […]

Artificially Reactivating Positive Memories Can Reverse Depression

Recalling Happier Memories to Reverse Depression

By artificially reactivating happy memories that were formed before the onset of depression, MIT neuroscientists have shown that they can cure the symptoms of depression in mice. The findings, described in the June 18 issue of Nature, offer a possible explanation for the success of psychotherapies in which depression patients are encouraged to recall pleasant […]

Kepler-138b: First Exoplanet Smaller Than Earth to Have Its Mass and Size Measured

 (Click for full image) The artistic concept shows the planetary system harboring Kepler-138b, the first exoplanet smaller than Earth with both a mass and size measurement. The sizes of the planets relative to the star have been exaggerated.

A team of astronomers have measured the mass and size of the smallest exoplanet yet, a Mars-sized planet named Kepler-138b orbiting a red dwarf star about 200 light years from Earth. Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science […]

New Research Shows Moon Engulfed in Permanent, Lopsided, Dust Cloud

LADEE Reveals Moon Engulfed in Permanent Dust Cloud

Using data from NASA’s Lunar Atmosphere and Dust Environment Explorer, a new study led by University of Colorado Boulder reveals that the moon is engulfed in a permanent, but lopsided, dust cloud that increases in density when annual events like the Geminids meteor shower spew shooting stars. “Knowledge about the dusty environments in space has […]

Deriving Power Directly from Evaporation

Researchers Produce Renewable Energy from Evaporating Water

In a newly published study, researchers from Columbia University detail the development of two novel devices that derive power directly from evaporation – a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car. Eva, the first evaporation-powered car, rolls along, thanks to a moisture […]

Dissolution is a Major Cause of Landscape Evolution on Titan, Possible Origin of Its Lakes

Close-up Image of Ligeia Mare

New research reveals that Titan’s surface dissolves in a similar process that creates sinkholes on Earth, finding that the dissolution process occurs on Titan some 30 times slower than on Earth due to the longer length of Titan’s year and the fact it only rains during Titan summer. Saturn’s moon Titan is home to seas […]

VLT Discovers the Brightest Distant Galaxy to Date and Signs of Population III Stars

VLT Discovers the Brightest Distant Galaxy to Date

Using ESO’s Very Large Telescope with help from the W. M. Keck Observatory, the Subaru Telescope and the NASA/ESA Hubble Space Telescope, a team of astronomers has discovered the brightest galaxy to date in the early Universe and discovered strong evidence that examples of the first generation of stars lurk within it. The newly found […]

Researchers Increase Energy-Burning Brown Fat Cells

New Discovery Could Help Researchers Increase Good Fat in Patients

A team of researchers has discovered a way to increase energy-burning human brown fat cells and to make them more active, a discovery that could have therapeutic potential for diabetes, obesity, and other metabolic diseases. Harvard Stem Cell Institute (HSCI) scientists have found a way to both make more energy-burning human brown fat cells and […]

GRACE Reveals That a Third of Big Groundwater Basins Are in Distress

Study Shows a Third of Big Groundwater Basins in Distress

Using data from NASA’s Gravity Recovery and Climate Experiment satellites, two new studies reveal that about one third of Earth’s largest groundwater basins are being rapidly depleted by human consumption. This means that significant segments of Earth’s population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings are […]

Study Reveals Ancient Climate of Mars Was Cold and Icy

Early Climate of Mars Was Cold and Icy

Using a three-dimensional atmospheric circulation model to compare a water cycle on Mars under different scenarios 3 to 4 billion years ago, researchers at Harvard believe Mars was cold and icy billions of years ago – not warm, wet and Earth-like. Cambridge, Massachusetts – June 16, 2015 – The high seas of Mars may never […]

Scientists Propose Possible Mechanism for Saturn’s Polar Cyclones

Model Predicts Cyclone Activity on Other Planets

Atmospheric scientists from MIT have developed a simple model that may predict cyclone activity on other planets. For the last decade, astronomers have observed curious “hotspots” on Saturn’s poles. In 2008, NASA’s Cassini spacecraft beamed back close-up images of these hotspots, revealing them to be immense cyclones, each as wide as the Earth. Scientists estimate […]

Researchers Show How Mechanical Forces Affect Cell Function

Researchers Show Mechanical Forces Role in Cell Function

New research from Yale University reveals how mechanical forces play an integral part in cell function. Nuclear membranes protect genes — life’s most precious cargo — but little is known about why they function in different tissue types. For instance, nuclei in brain cells tend to be soft and pliable while those in bone cells […]

Scientists Discover Evidence of Methane in Martian Meteorites

Scientists Discover Methane in Mars Meteorites

A newly published study details the discovery of methane in Martian meteorites, a possible clue in the search for life on the Red Planet. The researchers examined samples from six meteorites of volcanic rock that originated on Mars. The meteorites contain gases in the same proportion and with the same isotopic composition as the Martian […]

New Evolution Study Reveals Massive Genome Shift

New Evolution Study Finds Massive Genome Shift in One Generation

By applying the latest tools of genome sequencing and analysis to preserved evidence from experiments carried out at Notre Dame in the 1990s, a new evolution study finds a massive genome shift in one generation. A team of biologists from Rice University, the University of Notre Dame and three other schools has discovered that an […]

New Model Helps Explain the Softness in Earth’s Lithosphere

Understanding the Softness in Earth’s Lithosphere

A new model from researchers at Yale University helps explain the drop in elastic stiffness in the middle of the Earth’s continental lithosphere. Lithosphere is the stiff layer of rock that lies atop the slow-motion convection of Earth’s solid, yet ductile, interior. It is the “plate” of plate tectonics, the system of interlocking fragments that […]

Pupil Diameter Linked to Task Performance

Pupil Diameter Predicts Task Performance

Researchers from the Yale School of Medicine reveal how changes in the activity of individual neurons during performance of a task correspond exactly to the diameter of the pupil, showing signatures of high arousal for a wide diameter and low arousal for a small diameter. If you want to know who is ready to perform […]
