TEHRAN, Mar 06 -Scientists have for the first time precisely calculated the extent of the "human footprint" on Antarctica, the portion of the southernmost continent marked by human activity.
TEHRAN, Mar 06 -"It is only a matter of time before these questions go from being academic to defining our response to a major threat," said researcher K.T. Ramesh.
TEHRAN, Mar 03 -"We found microbes adapted to high salt levels, similar to what may be expected in the Martian subsurface," researcher Stephen Pointing said.
TEHRAN, Feb 25 - Pacemakers are electronic devices implanted to regulate your heartbeat -- usually because of a condition that slows your heart's normal rate. Traditional pacemakers have two parts: a battery-powered pulse generator implanted under the collarbone, and insulated wires that connect it to your heart.
TEHRAN, Feb 25 - "Being able to fully describe the molecular changes that are going on in memory is enormously appealing," researcher Daniel Merritt said.
TEHRAN, Feb 12 -"The new images are creating scientific puzzles about how such an object could even be formed," scientists Alan Stern said. "We've never seen something like this orbiting the sun."
TEHRAN, Feb 03 -"We were also able to identify exactly what aspects of the shape were most responsible for the strong performance of the fastest wings," researcher Leif Ristroph said.
TEHRAN, Jan 26 -"With further development we think it will be possible to make animal models of complex human genetic diseases, like arthritis and cancer, that are not currently possible," said researcher Kimberly Cooper.
TEHRAN, Jan 17-Scientists say they have developed what they call the “Planetary Health” diet, an ideal dietary regimen mostly based on vegetables and fruits, which, if adopted, can “prevent” more than 11 million premature deaths around the world each year.
TEHRAN, Jan 16 - When sending spaceships out to explore the solar system, scientists are limited by how far the ship’s fuel can take them.One novel solution being explored is a steam-powered craft that mines water on planets, comets or asteroids as it goes, which advocates say can theoretically explore space “forever.”
TEHRAN, December 30-As populations in arid and semi-arid regions grow, additional pressure is placed on already stressed water resources. In hopes of easing the pressure, some scientists are looking to nature for new and sustainable water-collecting strategies.
TEHRAN, December 02 -Scientists can improve the mood of people with depression by delivering electrical currents directly to affected regions of the brain, a new study says.
TEHRAN, November 29 -"If we think of sci-fi scenarios in which glowing plants replace street lights -- this is it. This is the breakthrough that can lead to this," researcher Fyodor Kondrashov said.
TEHRAN, November 10 -Under the right conditions, a dinosaur's soft tissue can be transformed and preserved, enabling fossilization. The process features chemical transformations similar to those that characterize browned or burnt toast.
