According to researchers

, they've found that exposure to short wavelength, or blue light, during the day can improve alertness and overall performance.

previous research has shown that blue light is able to improve alertness during the night, but our new data demonstrates that these effects also extend to daytime

A recent study suggests that Tetris could actually help dieters reduce cravings

examine how the game can affect people's carvings

researchers created two study groups: One that played Tetris for three minutes while the other group was told that the game was loading but they never received the chance to play

The publishers Springer and IEEE are removing more than 120 papers from their subscription services after a French researcher discovered that the works were computer-generated nonsense.

Small satellite-tracking devices attached to sea turtles swimming off Florida's coast have delivered first-of-its-kind data that could help unlock they mystery of what endangered turtles do during the "lost years."

"lost years" refers to the time after turtles hatch and head to sea where they remain for many years before returning to near-shore waters as large juveniles

The time period is often referred to as the "lost years" because not much has been known about where the young turtles go and how they interact with their oceanic environment

Hoyle coined “Big Bang”

In 1949, Fred Hoyle unintentionally coined the term “Big Bang” as a household name, in a scripted radio broadcast on the BBC Third Programme. His talk was printed in the The Listener (7 Apr 1949). He compared his own belief in a “steady state” universe, saying, “earlier theories … were based on the hypothesis that all the matter in the universe was created in one big bang at a particular time in the remote past.” He repeated its use in a 1950 broadcast published in The Listener (9 Mar 1950): “One [idea] was that the Universe started its life a finite time ago in a single huge explosion… This big bang idea seemed to me to be unsatisfactory.” His critics found the “big bang” term pejorative, yet Hoyle has said his intention was to make a vivid description for the radio audience. The term stuck

NASA’s Mars Curiosity rover can’t find any sign of methane on the red planet, but the agency emphasized that methane would be only one indicator of possible life

this addresses only one type of microbial metabolism

Marie Byrd Land is a desolate region of Antarctica buried deep beneath the West Antarctic Ice Sheet

Historic eruptions have punctured the ice sheet, creating a chain of volcanoes amid the ice

researchers have shown that molten rock still stirs deep underground

Astronomers using data from NASA's Kepler and Spitzer space telescopes have created the first cloud map of a planet

known as Kepler-7b

Previous studies from Spitzer have resulted in temperature maps of planets orbiting other stars

NASA-funded researchers have spotted the first signs of an "exomoon," and though they say it's impossible to confirm its presence

The discovery was made by watching a chance encounter of objects in our galaxy, which can be witnessed only once

won't have a chance to observe the exomoon candidate again

The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed by observations with both the W. M. Keck Observatory and the Gemini Observatory

The initial discovery, made by NASA's Kepler Space Telescope, is one of a handful of smaller planets found by Kepler and verified using large ground-based telescopes

his Earth-sized planet, one of five orbiting this star, which is cooler than the Sun, resides in a temperate region where water could exist in liquid form

This is the first transit of the sun by a planet observed from any planet other than Earth, and also the first imaging of Mercury from Mars

Mercury fills only about one-sixth of one pixel as seen from such great distance, so the darkening does not have a distinct shape, but its position follows Mercury's expected path based on orbital calculations.

The observations were made on June 3, 2014,

This October, a comet will brush

NASA’s Curiosity rover has just pulled into

terrain chock full of curvy rock outcrops at Kimberly that’s suitable for contact science and drilling action

The robot’s arm has been deployed to investigate the most scientifically productive spots

Original mission: International Sun/Earth Explorer 3 (ISEE-3)

to investigate solar-terrestrial relationships at the outermost boundaries of the Earth's magnetosphere

to examine in detail the structure of the solar wind near the Earth and the shock wave that forms the interface between the solar wind and Earth's magnetosphere

In the days leading up to some recent moderate-sized earthquakes, instruments nearby have picked up brief low-frequency pulses in Earth’s magnetic field

A few scientists have proposed that such pulses, which seemed to become stronger and more frequent just before the earthquakes occurred, could serve as an early warning sign for impending seismic activity

Now, a team has come up with a model for how these magnetic pulses might be generated, though some critics say they may have a humanmade origin.
