Martian carbon dioxide clouds tied to atmospheric gravity waves
On 4 March 1997 the Mars Pathfinder lander fell through the thin Martian atmosphere. During its descent, instrumentation aboard the lander recorded the changing atmospheric temperature, pressure, and density.
Heart Lake holds water for Yellowstone's hydrothermal diversity theory
Within Yellowstone National Park, the water emanating from the park's famous hot springs and geysers seems to belong to either one of two distinct types. In some areas, subterranean waters rich in chlorine and dissolved silicates ...
Dogs succeed while chimps fail at following finger pointing
Dogs are better than chimps at interpreting pointing gestures, according to a study published in the online journal PLoS ONE.
Study proves plausibility of new pathway to life's chemical building blocks
For decades, chemists considered a chemical pathway known as the formose reaction the only route for producing sugars essential for life to begin, but more recent research has called into question the plausibility of such ...
New climate-cooling molecule found
Scientists have succeeded in detecting and analyzing a new atmospheric molecule whose existence has long been suspected but never proved.
Of orbits and ice ages: Researcher confirms that axis shifts help to propel temperature changes
Though it was first suggested well over a century ago, the hypothesis that changes in Earths orientation relative to its orbit influence the growth and decline of ice sheets was only recently tested.
Four reasons why the quantum vacuum may explain dark matter
Evolutionary biologist Lynn Margulis dies in Mass.
Evolutionary biologist, author and National Medal of Science winner Lynn Margulis (MAR'-guh-liss) has died.
Ingredients involved in splashing revealed
"Splashing" plays a central role in the transport of pollutants and the spread of diseases, but while the sight of a droplet striking and splashing off of a solid surface is a common experience, the actual physical ingredients ...
Finnish researchers discover regulator of human cell activity
The research teams headed by Prof. Johanna Ivaska (University of Turku and VTT Technical Research Centre of Finland) and Prof. Marko Salmi (University of Turku and the National Institute for Health and Welfare) have discovered ...
Pumice proposed as home to the first life forms: A new hypothesis in Astrobiology journal
The glassy, porous, and once gas-rich rock called pumice may have given rise to early life forms, according to a provocative new hypothesis on the origin of life published in Astrobiology, a peer-reviewed journa ...
New hypothesis on crater debris
A team of researchers partnered with the NASA Lunar Science Institute (NLSI) has developed a new hypothesis for the origin of crater ejectadebris that is launched out of a crater during meteorite impacts.
Pressure for positive results puts science under threat, study shows
Scientific research may be in decline across the globe because of growing pressures to report only positive results, new analysis suggests.
